[honest python]

Yeah, that fixed it after all. Dunno what I was doing before. Thanks. ^^

[waxen sandal]

Maybe fieldWidth? I always confuse them ;P

[honest python]

It seems to still stretch to fit though.

Oh, that might be it. 😄

[waxen sandal]

wdym stretch?

[honest python]

Well I set it to 50 and thankfully it stretched to split the horizontal area in 3 parts. Since I've got a sort of a table below it, I was hoping to keep the dimensions, so it does that as expected.

Needs some fiddling but it's all aligned

[waxen sandal]

Oh, then GUILayout might not be the best solution

Manually calculating layout is a better idea in that case

EditorGUI.LabelFIeld instead of EditorGUILayout

[honest python]

Yea I see what you mean

[visual stag]

Using GUI.Label instead of a label field night be advisable

[vapid prism]

How can I change the behaviour of Right Click -> Copy/Pase on a field of my custom type? Atm it's copying some seemingly random int32 but my type is more complex than that

[maiden vale]

in this old thread https://answers.unity.com/questions/542890/scene-color-object-marking.html
they are getting the texture of that "Colored Pill" with labelIcons = GetTextures( "sv_label_", string.Empty, 0, 8 );
What would be the current way of getting this texture?

[cold veldt]

I want to make an extension so that I can "on demand remap" all of my assets in a folder at once to use ones that already exist instead of their own sub-asset materials, but frankly I have barely any clue where to start with accessing any of that data

[glad pivot]

is it possible to make custom editors for structs?

or does it need to be a class? i also tried making an editor for just a basic default c# class and the target didnt want to cast to the class because it was not derived from UnityEngine.Object

[waxen sandal]

Editors are only for Unity Objects (most commonly monobehaviours)

PropertyDrawers work for normal classes

[glad pivot]

ok, so i just want to have a popup field within a regular c# class or struct, how would i do that with a property drawer? im reading the documentation and trying stuff out rn

ok i think i have something that may work but im not sure how to apply the property drawer

how do i change the serializedproperty i get from property.FindPropertyRelative("Index"); ?

it seems like the problem is EditorGUILayout.popup

i figured it out no need to reply 👍

[snow summit]

Is it possible to feed script variables directly to a shader?
I'm trying to make a custom debug overlays in the scene view that changes the color of the overlay depending on the number of material elements on the mesh renderer.

The two ways I've tried:
-Write the data in the meshes. Unfortunately I cant edit the meshes.
-Using materials and feeding the variables by script. camera.RenderWithShader dosent accept materials of course

What are my options?

[glad pivot]

this is probably a question for #archived-shaders

but yes you should be able to pass variables to shaders. you can do Material.setFloat() and other things like color and so on

[snow summit]

Yeah thats the way I would do it but I can render the scene using a material. I need to use a shader to assign it to the camera

[twilit kernel]

Hey guys, I created a game object that has no image component on it, and it has two children that do have an image on them.

My question is, how do I make the parent have an image when looking in the assets folder. Mainly so i can tell apart the prefabs by image and not just by name

[glad pivot]

you probably need to elaborate more on what you mean, idk if you mean you have three prefabs and two of them are variants or if these are scripts that derive from a monobehaviour

[twilit kernel]

there is only 1 prefab that consists of a parent gameobject with 2 children

this is what i see in the assets folder

and this is when the prefab opened

the only thing "Item01" has is a transform and sorting group

Top/Bottom have a transform, sprite renderer, sorting group

I want the Item01 prefab to show me the image of one of the children instead of this gray box

[rigid plover]

I'm trying to make sliders in a list of structs not go over a certain total number, however I don't know how to make it check which value has changed without making custom sliders.
What would be a good solution?

[gloomy chasm]

There is two ways to do it. Either you handle the list drawing yourself, and use a Begin/EndChangeCheck around each item when you draw it. Or before drawing you cache all of the current values and then compare them to the values after drawing to know which changed.

[coral plover]

are there any plugins recommended for writing custom inspectors? I have Odin from a bundle but that seems to be focused more around reworking existing inspectors.

[barren moat]

I hack I've used is to check if it's over some length in OnValidate and delete the excess members

But obviously you could do better with a custom drawer if you wanted to

[rigid plover]

True, though it would be a pain with a custom one if I ever wanted to add/change the members of the struct

[rigid plover]

Went with the caching solution, works very well, thank you!

[patent venture]

how can i access builtin unity overlays through code: specifically the orientation one here?

[honest python]

Hey guys, is there any way I can get to size of this gutter/margin/padding/offset...?

I've tried looking it up but I haven't found anything.
My ultimate goal here is to be able to add the same spacing on the right side.
My current code

EditorGUILayout.Space(mapTex.height);
var spaceRect = GUILayoutUtility.GetLastRect();
EditorGUI.DrawPreviewTexture(texRect, mapTex);

Draws the tex all the way up to the right border, which is ugly. 😦

[waxen sandal]

It's uhh 16 px

Or did they increase it to 18? 🤔

It's the indent size iirc but that's not publicly available for some reason

[atomic flower]

Sorry, I know that's confusing and probably not enough info. Still figuring my way around extending the editor

[granite tartan]

Hi there! How would I go about changing the scripts icon to a custom one?

[loud vortex]

Why does my ScriptableObject doesnt serialize it's values when i set them through a inspector script, but does serialize when i set them through the inspector on the scriptable object itself

[gloomy chasm]

You set the icon on the .cs file in the inspector (top left). If you need more info there is a lot of results on google for doing exactly this.

[gloomy chasm]

You are not dirtying it after changing the values.

[short juniper]

Don't know where else to ask,
Using github copilot with VSC for unity, I find I'm able to write a comment i.e //draw debug of overlapcircleall then on the next line copilot suggests me some code, which is fantastic
Though this is hit and miss, sometimes when I write comments copilot just doesnt engage with it. Anyone know why? Any methods to get copilot to be more verbose? An example of a line copilot doesnt engage with is //find which collider is closest to the mouse

[granite tartan]

Thanks for your response. However, I don't want to set the icon of the GameObject rather the "script icon" that you see in the screenshot I posted.:)

[gloomy chasm]

I know, you select the .cs file in project browser and then set the icon via the top left of the inspector.

[granite tartan]

Thank you! That was a lot easier than I thought.

[wheat dagger]

Any way to fail the build when custom validation fails?
I have a static method with [DidReloadScripts] which validates some important things using Unity's TypeCache. Play mode should be blocked until those issues are resolved, just like compiler errors. I have found the BuildFailedException, but throwing that in that method doesn't fail the compilation.

using CompilationPipeline.compilationFinished, when I throw a BuildFailedException, it just... prints the message as a regular log. Not even as an error.

[earnest trench]

Hello guys, I need to know if there is a proper way to evaluate energy cost inside unity, like on profiler or an external tool or plugin? If so how do i do it?

[smoky wave]

With OdinInspector, this is possible, see e. g. https://odininspector.com/attributes/foldout-group-attribute , but I guess there is nothing out of the box. What @torpid elm suggested could be used, but this will require editor scripting which then either draws the inspector content exactly as you want it (which requires more work to keep it up to date), which could be used to rebuild what OdinInspector offers here.

[gloomy chasm]

What do you mean "energy cost"?

[shadow minnow]

I'm writing an editor script that generates a palette and an indexed image from a source image, and i need the script to save the texture2Ds i'm building as PNG files

texture2D.EncodeToPng(); gives me a byte[] that i can write to a file, but to do that i need to use System.IO to write that data to a file

but the file system is different between System.IO and unity's AssetDataBase class

is there a clean way to save a PNG as a unity asset using AssetDataBase? I can do CreateAsset(path, texture) to save the generated Texture2D, but this isn't a PNG

Like is there a way i could literally just create an asset from a byte[]

[abstract olive]

for some reason, my custom editor window isn't registering any events except for Layout and Repaint in the onGUI() function, does anyone know any common causes of why this might be? I used the UI Builder to create the editor, and then added some code to do some other things for the UI but for some reason I can't get events like MouseDown or MouesDrag anymore (was working before I started using UI Builder)

keyUp and keyDown are working but nothing mouse-related seems to

[short tiger]

No, Unity depends on the file extension to recognize which importer to use. The options you've mentioned are the only ones you have, either you save the Texture2D directly with CreateAsset or create a file with System.IO.

You can get the path to the Assets folder with Application.dataPath

im writing a property drawer for a basic c# class which is going to be used within a list. but im having a problem where the list GUI is not in capsuling the class's GUI. where do i change the size of the list GUI?

This code loads manager scene before I enter play mode. But it does not wait for managers scene to load, how can make it so it waits?

[stuck agate]

how do i make the space inbetween these smaller

like this

[stuck agate]

I'm a bit closer but I have lost my indent for some reason

[glad pivot]

in a list like with a custom propertyDrawer like this, how can i get the element index?

this number right here

[gloomy chasm]

LabelWidth, or just use a Vector2 field.
https://docs.unity3d.com/ScriptReference/EditorGUIUtility-labelWidth.html

[gloomy chasm]

You have to read the propertyPath. If it is a element in an array it will end with [n]. n being the index number.

[stuck agate]

and why does the indent go away when I use EditorGUILayout.BeginHorizontal();

its doing the indent

but like horizontally

thats weird

[gloomy chasm]

Because iirc it only indents fields, not all layouts. But I could be misremembering

[stuck agate]

o

[glad pivot]

thanks

[stuck agate]

how would I change the Y label to a Z

I want X and Z

not X and Y

[gloomy chasm]

Ahh, would need to use reflection to get the internal multi field.

[stuck agate]

reflection?

[gloomy chasm]

Its complicated. Basically a way to access members (fields, methods, properties) from other classes, even if they are private. But again, it is complicated and error prone.

[stuck agate]

like this looks really good apart from the fact that it says Y

[plucky coral]

Hello, this is my class (picture 1). I only want to make prizeAmount appear in the inspector if my dailyRewardType is set to DailyRewardTypes.Item, is this possible and if so then how?

[gloomy chasm]

You can use the PreviewRenderUtility to do it. You can also do it manually by creating a preview scene and rendering it with a camera.

[gloomy chasm]

You just inherit from ScriptableObject. Other option is to handle the serialization/data yourself with a custom file extension and make a custom importer for it.

[whole steppe]

and when I do this

update!!!:

1. I didn't get banned, so there's that!
2. the new snippet did what I needed-ish! so cheers! ig...

using UnityEditor; internal sealed class SceneViewFocus : EditorWindow {
    [InitializeOnEnterPlayMode] private static void _() =>
        EditorApplication.delayCall += () => FocusWindowIfItsOpen<SceneView>();
}```
it's like, yea... entering play-mode then switching to the scene-view for a fraction of a second and then immediately goes back to the game-view...
I'm trying to keep the focus on the scene-view even when entering play-mode, this Unity version I'm using doesn't support it by default unlike newer versions I've used before!

any idea how that would be done?

and by keeping focus, I don't mean keyboard focus, but like the actual view!

[whole steppe]

I'm probably gonna get banned, just so you know, I love y'all! 💖

[south beacon]

Hii, I'm trying to build a simple custom PropertyDrawer for my serializable class. If I try to draw a list of these classes in the inspector it will pad the list correctly but place the actual fields just below it, instead of inside it. I suspect that EditorGUILayout is not intendet for PropertyDrawers. Is this correct, or is there a simple thing that I'm missing?

public class ConKnockbackHandlerDataDrawer : PropertyDrawer
{
    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        EditorGUI.BeginProperty(position, label, property);

        void CreateRect(string field)
        {
            SerializedProperty child = property.FindPropertyRelative(field);

            EditorGUILayout.BeginHorizontal();
            EditorGUILayout.PrefixLabel(field);
            EditorGUILayout.PropertyField(child, GUIContent.none);
            EditorGUILayout.EndHorizontal();
        }

        EditorGUILayout.BeginVertical();
        CreateRect("handlerType");
        CreateRect("applyType");
        CreateRect("curve");
        CreateRect("fixedImpulse");
        CreateRect("directionalImpulse");
        EditorGUILayout.EndVertical();

        EditorGUI.EndProperty();
    }

    public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
    {
        return EditorGUI.GetPropertyHeight(property, includeChildren: true);
    }
}```

Thanks!

[atomic flower]

I'm creating a property drawer for a custom class - it's a POCO that doesn't subclass anything, but I marked it with the serializable attribute. I'm able to draw it just fine, but when I try to cast the serialized property's target field so I can access a public field on the class, I get an error. Is there a way to cast the target without making the object inherit from a Unity object?

[gloomy chasm]

Only with lots of reflection and complicated code. But 99.5% of the time you should not be accessing it. Instead, use the SerializedProperties.

[atomic flower]

Cool, thanks

[whole steppe]

Hello- does anyone know how to set a material here? I'm using the modelImporter to set everything else but can't access this field https://i.imgur.com/Ho7JIJq.png

[short tiger]

This is possible in Unity 2022, with the SerializedProperty.boxedValue property, though I'm not sure if you get a copy or the actual instance (when dealing with serialized classes, that is)

[tight pine]

Hey ppl! Been looking for a hook (event) for when an element is added to an Array or a List on the default drawer (by clicking the + icon or changing the List size on the text box). Any of you done that before?

This is on an editor window, not the inspector (if it makes any difference)

[gloomy chasm]

Unless I am mistaken, you can only get the 'base' types (float, int, string, Vector3 etc.). And not just any old POCO. And even if you could, you still shouldn't.
Edit: Nope, looks like I am mistaken and you can. But still should not in most cases.

[gloomy chasm]

You will need to handle the drawing of the list yourself with ReorderableList(IMGUI), or ListView(UIToolkit)

[tight pine]

Ho dang 🤦🏻 whyyyyy 😭

[gloomy chasm]

There are other ways maybe depending on what you are doing exactly.

[tight pine]

Just need to do some edits to the objects when they are added to the list. When the user presses the + button it copies the last element on the list and I need to make sure the edits are done on that element as well.

[gloomy chasm]

A workaround would be to get the array size before drawing and then again after drawing and compare to two.

[tight pine]

hoooooo..... That's a nice one!

I'll try it out 🙂

[short tiger]

The example given in the documentation shows it being used to access a serializable struct. I don't agree that it should be avoided. You could argue you shouldn't access vector3Value for the same reason, because you can access xyz through FindPropertyRelative instead.

[gloomy chasm]

Yeah I noticed that.
I should also amend my statement about it being used. The reason I say that is that a lot of the time, SerializedProperty should actually be used, instead. And I fear that for people who are newer to editor scripting will not understand when it should or should not be used and lead to poor use and confusion. SerializedProperty is already confusion enough for people.

A lot of the time people would also use it as a crutch to avoid actually understanding SerializedProperties. That is why I would avoid recommending it.

[short tiger]

Okay, I can agree with that. It can be used irresponsibly. So in the future, I will be asking for more clarification on the use case before recommending either boxedValue or FindPropertyRelative.

[gloomy chasm]

Sounds good. And to be clear, I do find it to be very cool and helpful! Just a bit 'dangerous' too haha

[atomic flower]

If I want to change a value in a class that’s being drawn by my property drawer, can I somehow use an instance method on the serialized object (eg, AddItemToArray(Item addMe) to mutate an array), or do I need to deserialize/serialize the field I want to modify?

[tight pine]

I've made an EditorWindow that manages some ScriptableObject. When I make a change and then hit undo, the change is undone on the scriptable object but not reflected on the window. If I close the window and open it again then it shows the right value with the "undone" change... That's weird no? Or do I have to do something specific to "refresh" the window when an action is undone?

[gloomy chasm]

Assuming you are using SerializedObject, in OnGUI, just serializedObject.Update()

[gloomy chasm]

I don't think I quite understand what you mean.

[tight pine]

ha so I should update it on each OnGUI pass?

[gloomy chasm]

Yup, at the top before drawing any fields for it or mutating it

[tight pine]

hoooooooooooo..... 🤦🏻‍♂️

[gloomy chasm]

Basically a SerializedObject is a copy of the 'source' data. That is why you need to do ApplyModifiedProperties. So you need to Update to update the SerializedObject instance to match the source data if it was changed by something else.

[atomic flower]

Basically, I have a private, serialized list that I want to add to/remove from. I would like to do some other things as well (validation, for instance), so using a method on my class would make sense, but I don’t know if it’s possible with a SerializedObject.

[tight pine]

Thanks a lot man, I have to take a moment and appreciate you, you're incredible! I do not come here very often, but anytime I have a weird problem (or I think I do 😃) and ask here you are always around and come up with a super insightful response on the spot. Are you sure you are not some super advanced AI that doesn't sleep and knows everything?

[gloomy chasm]

Got it, ask MentallyStable mentioned if you are using a newer version of Unity you can just get it via boxedValue.
The other way (and what I would probably use) is to get the array via SerializedProperty, var arrayProperty = serializedProperty.FindRelativeProperty("m_MyArrayOrListField");

You can add to it via arrayProperty.arraySize++. And there are a number of methods that can only be used on serialized properties for arrays. Like .GetArrayElementAtIndex(..)

[gloomy chasm]

Aw, well thank you! I am glad I could help, I love editor scripting, so I enjoy helping others here. 😄
There is a non 0 chance that I might be an AI. Just don't tell ChatGPT, I wouldn't want it to get jealous 😛

[atomic flower]

Thanks a ton! Not the first time you’ve helped me out, so to echo @tight pine , thanks for lending your knowledge and patience here!

[surreal torrent]

Is there a way for me to disable variable fields from a class variable?

Essentially, I have a class object with multiple variables in it. I can disable/hide/grey out properties from the main script the editor controls but not individual variables within the class object variable on that script.

The gun property field is the class object.

[surreal torrent]

I can get the property fields using the following code, but not sure if I can disable those fields using this method?

WeaponManager t = (WeaponManager)target;
        foreach (var property in t.guns.GetType().GetFields())
        {
            if (property.Name == "test")
            {
            }
            else
            {
                GUI.enabled = true;
            }
        }

[tawdry granite]

Hello, anyone made an editor extension to fast apply colors to images?

[gloomy chasm]

You would draw each field using Property field, so you would get the 'sub properties' of the one containing the one you want to disable.

[alpine bolt]

I have these ScriptableObject types MyCustomTypeSO : IMyCustomInterface, ScriptableObject. What should be the most performative way of storing this IMyCustomInterface object and getting the object reference and not a "copy" on Unity rebuild? I'm thinking of saving a GUID and then having a [NonSerialized] object checked. If null, I Resources.LoadAll(savedPathString).FirstOrDefault(x => x.GUID == myGUID)

[smoky plover]

what is the difference from [ExecuteAlways] and [ExecuteInEditMode]?

the normal OnValidate method is called less times than ExecuteAlways Update method?

[alpine bolt]

https://docs.unity3d.com/ScriptReference/ExecuteAlways.html have you read this?

[smoky plover]

yes

[gloomy chasm]

not needed, it works as is

[gloomy chasm]

Reading the docs. Looks like ExecuteInEditMode does the same thing but is being deprecated. So use ExecuteAlways

[smoky plover]

it isn't deprecated

[gloomy chasm]

being deprecated, going to be

[smoky plover]

Ok, didn't notice that

[alpine bolt]

The [ExecuteInEditMode] docs say: To indicate that a MonoBehaviour correctly takes Prefab Mode into account and is safe to have open in Prefab Mode while in Play Mode, the attribute ExecuteAlways can be used instead of the attribute here.. Tbh I just tested a prefab and ExecuteInEditMode worked the same as ExecuteAlways

[smoky plover]

anyway my code with OnValidate doesn't get executed, while the same code trasmigred to [ExecuteAlways] Update works

Is it correct or i'm missing something?

[short tiger]

OnValidate is only called when the script is first loaded or when a value changes in the inspector.

[fierce cave]

I've been adding a tile properties via inhertiting Tile. I've noticed that the preview is no longer there. Is there any way i can add the tile preview back (and hide all the debug properties of the tile)

[timber stump]

I wrote a custom gridBrushBase script that keeps references to prefabs, and it finds all tilemaps parented to the prefab and places them to tilemaps in the scene with the corresponding order in layer.

There is an editor script that makes a preview for that too, including any sprite renderers parented to the prefab.

It was working fine, but now it's very slow. I didn't change anything.

And I'm not sure what the issue is.

Would anyone be willing to see if they can pinpoint an issue with these scripts that might be causing that?

[gloomy chasm]

The profiler is great for this sort of thing 🙂

[timber stump]

Well yes, but that isn't really helpful to me. I did give the profiler a go.

Maybe I can share a screenshot?

I'm not entirely sure how to decipher the issue

The profiler info I mean

[gloomy chasm]

There some great docs on it with a lot of screenshots! 😄 https://docs.unity3d.com/Manual/ProfilerCPU.html

You will probably want the "Hierarchy" view

[timber stump]

Yeah, so it seems to be mostly SceneView.OnGUI.Layout and SceneView.OnGUI.MouseLeaveWindow

[gloomy chasm]

I would switch to Deep Profile mode and try again in that case

[timber stump]

Okay so I tried some things and it was the refreshing of all of the tiles in the scene

If the scene is too large, that will basically crash the editor

I plan on breaking things up into subscenes using anyway, so I'll just keep that in mind

The script does work fine.

Any idea how to prevent a total scene refresh?

[earnest talon]

Is there a way to use C# calls directly to add things to menus instead of with Attributes? (e.g. replace MenuItemAttribute with a call directly to UnityEditor's topbar menu?)

[simple cove]

I don't think that's supported. Afaik C# is sandboxed in the editor, so it'd have to recompile.

What I'd do is create a 'Open MyEditor' menu item that opens an EditorWindow, which I'd be able to update real-time.

[earnest talon]

I'm not making an editor window. I'm trying to sandbox the editor window creation process into one namespace, kind of like a redirect of sorts.

Reason being is I want to make Editor Windows easier for others in my university to create though is still fully compatible with Unity's UIElements namespaces, which is why I spend time adding (and extensively documenting) all the changes and additions I do.

[simple cove]

the related code is hardcoded to work with attributes https://github.com/Unity-Technologies/UnityCsReference/blob/master/Editor/Mono/EditorMode/MenuService.cs#L192

[earnest talon]

A bit annoying but maybe there's a means to reroute the MenuItem attribute instead, bypassing the sole reason for requiring UnityEditor namespace at all.

[simple cove]

well.. not really

[earnest talon]

So it is just one of those really annoying things where you either

A) have to crack open the code directly (somehow, and probably breaking TOS in the process)

[simple cove]

you could do something like this if the whole goal is to have an external dll extend unity editor, but you'll still need to add a reference to UnityEditor when including the .dll to your project

#if UNITY_EDITOR
using MenuItem = UnityEditor...MenuItemAttribute
#else
using MenuItem = MyLib.MenuItemAttribute;
#endif

#if !UNITY_EDITOR
public class MenuItemAttribute : Attribute { }
#endif

[earnest talon]

ah

what I'm trying to do is implement a custom attribute

that acts as a reroute to MenuItem

so that it's contained in one namespace without DLLs

It's one framework folder inside Assets > Editor (for now) full of Mono-C# scripts that just make the process abstracted and simpler to pick up

[simple cove]

what's B in this case? I don't see another way 😛

[earnest talon]

B) require UnityEditor's namespace all the time

It's pretty much just nit picking but despite that

I don't know if there's any security concerns with exposing UnityEditor.MenuService

or even an MainMenu.AddItem(pathString).

[simple cove]

yeah the code in the link I posted doesn't look like quality code. might be super old or something.. probably passed as 'good enough'

[earnest talon]

speaking of, I'd like your input on using the dynamic keyword

[simple cove]

mind that you're probably the first that wants to extend the menu without referencing UnityEditor assembly lol

[earnest talon]

probably, which sucks for me

[simple cove]

dynamic? no.. why?

[earnest talon]

abstracted get-set for SerializedProperty.typeValue

I've done it, it works but it requires specific values

and I'm working on safer GetValue(out valType) and already got a safer SetValue(object value) working

[simple cove]

meh if you make everything else robust then I wouldn't mind

I'm doing my absolute best to restrict it to only what SerializedProperty can take

at first I thought it didn't work but no that was my fault at the time - specifically because I tried to set a bool value to a string serializedproperty value.

[simple cove]

but I think manually branching it to a per-type logic would be better.. there are only a couple you need to handle probably

[earnest talon]

it works, it's just very picky on what it wants to do.

There's 20, technically 26 but 6 I don't handle from SerializedPropertyType because it's too vague for those ones (specifically, what are they setting as they don't exactly have typeValues connected explicitly to a SerializedProperty object)

SetValue right now doesn't check for type compatibility between object value and the serializedProperty.typeValue, which I'm rectifying now

all in all, I just want to make creating editors and filling their contents a lot easier and less longer than the gargantuan lines that can be. Especially with enums - shudder

I'm completely fine with doing the gargantuan lines personally but I know a lot of people at my university do not even want to touch them, one reason being the really long, almost-god-line structure that can be just setting property children.

All I can do is try abstract it, create a owner>parentproperty>childproperty like hierarchical navigation method

and so on, so forth

[simple cove]

why not object instead of dynamic?

[earnest talon]

works for set but won't for get.

[simple cove]

I don't think you should ever be needing 'value' like that (?) I've dealt with editor stuff a lot but never had this need. Are you certain it's necessary?

[earnest talon]

I can do object technically, with an asterisk but it's got it's own concerns too

sometimes object would error where dynamic wouldn't.

not IL2CPP compatible, which would be a concern if it wasn't an Editor window.

[simple cove]

reason is that you usually know the type of the field you're working with, and I can't think of any reasons to want to obtain the value when you don't know the field's type

ah, maybe if creating a custom .meta thing or something 😄

[earnest talon]

it's definitely weird

object works (again asterisks, I've found use-cases where this is kinda not the case)

dynamic is just object, resolved at runtime (bypassing the compiler)

[simple cove]

yeah usually dynamic is there to replace unknown types.. and sometimes MAYBE complex generic ones

[earnest talon]

the part about value and why I include it is

It's meant to be a quicker method if you're absolutely sure on what you're doing

e.g. you know your scripts' types and their data types inside and out, you know what you're expecting to get and what it expects back.

otherwise, there's shorthands if you want to be extra safe

(boolValue > Bool)

even without dynamic I'll still need to keep the warnings (thank god these kinds of changes are one word)

I'm also going to be adding safer methods like I said

object will at least remove some of the overhead caused by using JIT-exclusive functionality.

[peak bloom]

dynamic uses Reflection.emit it won't work in Unity

[jovial forge]

Unable to find player assembly: \StagingArea\Data\Managed\UnityEngine.TestRunner.dll
How do I get this Test Runnen in Unity 2021?

[simple cove]

why wouldn't it? System.Reflection is referenced in unity's assemblies

[simple cove]

yeah in that case I think object should suffice. Some boxing when wrapping value types won't hurt the inspector's performance anyway :p

[waxen sandal]

Probably because of il2cpp

[simple cove]

mind elaborating? 😛

[gloomy chasm]

Reflection.emit doesn't work in IL2CPP builds, but should work fine in editor iirc

[simple cove]

ah, alright, thanks. Yeah it's fine in editor & non-il2cpp builds, so was wondering what was that about

[earnest talon]

Dynamic does work. It did work with all types when I had .value as dynamic. Because UnityEditor is Mono-based, not IL2CPP, it's able to make use of dynamic values. Though performance is eh.

It's a JIT-Exclusive benefit.

IL2CPP being AOT only.

[glad pivot]

so ive been trying to figure out why my editor window does not want to open when i load any layouts or reopen the project. The log that appears when it fails to load is this

UnityEditor.WindowLayout:LoadDefaultWindowPreferences ()

I had some help by someone and we figured out that the issue is most likely somewhere with my use of #if UNITY_EDITOR as we tried to compile the c# code outside of unity and it failed, and only successfully reopened the window until we removed enough of the #if UNITY_EDITOR instances and code but now that im trying to pinpoint which part of my code is causing the issue i am unable to do it. I have commented out essentially everything related to the editor window and unity still dont want to load the window. if anyone could check out the code to try and figure it out id be really grateful. (there are definetively stuff in the code that is not good practice so dont worry about that im working on it as this post may show)
https://github.com/HenrysHouses/MultiSceneTools

[astral crown]

alright, so I'm trying to make a small change in my script. I'm trying to have two column in a single row of gameobject and strings. GameObject works, but strings always resets and I understand that it's because I need to use serializedObject, but I don't get how to use it in my project for exemple. Could someone help understand it? It would be really appreciated! I tried some random things in the comments section of the code below:

public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        EditorGUI.BeginProperty(position, label, property);

        position = EditorGUI.PrefixLabel(position, new GUIContent("Piece"));

        int indent = EditorGUI.indentLevel;
        EditorGUI.indentLevel = 0;

        Rect gameObjectRect = new Rect(position.x, position.y, position.width / 2 - 10, position.height);
        Rect stringValueRect = new Rect(position.x + position.width / 2, position.y, position.width / 2 - 5, position.height);

        SerializedProperty gameObjectProperty = property.FindPropertyRelative("gameObject");
        SerializedProperty stringValueProperty = property.FindPropertyRelative("stringValue");

        // SerializedObject serializedObject = new SerializedObject(stringValueProperty.exposedReferenceValue);
        // serializedObject.Update();
        // serializedObject.ApplyModifiedProperties();

        EditorGUI.ObjectField(gameObjectRect, gameObjectProperty, new GUIContent());
        EditorGUI.TextField(stringValueRect, stringValueProperty.stringValue, new GUIContent("").ToString());
        
        
        EditorGUI.indentLevel = indent;

        EditorGUI.EndProperty();
    }

Here is the result:

Right now, the word "Element n" is being replaced by Piece if some of you were wondering (because I didn't like it XD)

[gloomy chasm]

You need to just pass the stringValueProperty instead of the .stringValue of it. Or, you need to set the .stringValue from the TextField (TextField returns a string of the changed/new value)

[astral crown]

Well I know that if I only use stringValueProperty it says: [Argument 1: cannot convert from 'UnityEditor.SerializedProperty' to 'UnityEngine.Object' [Assembly-CSharp]] and I can't cast it or anything like that

well In the serializedObject

[gloomy chasm]

From:

EditorGUI.TextField(stringValueRect, stringValueProperty.stringValue, new GUIContent("").ToString());

To:

EditorGUI.TextField(stringValueRect, stringValueProperty, new GUIContent("").ToString());

Or to:

stringValueProperty.stringValue = EditorGUI.TextField(stringValueRect, stringValueProperty.stringValue, new GUIContent("").ToString());

[peak bloom]

dynamic requires JIT compilation, which is not possible on AOT, in this case, IL2cpp

[astral crown]

for your first recommendation : EditorGUI.TextField(stringValueRect, stringValueProperty, new GUIContent("").ToString()); it says Argument 2: cannot convert from 'UnityEditor.SerializedProperty' to 'string'
And your second approach didnt do any errors but it's still resets what im writing in my inspector

[gloomy chasm]

Ah yeah, some fields accept SerializedProperty and some don't I forget which ones are which, sorry.

Lol, the reason the second one isn't working is because you need to reverse the value and the GUIContent

It is position, label, value, style

You can also just not use a label

[astral crown]

Oh don't worry. I'm reeeeaally new to that and honestly I'm not sure of what Im doing myself XD... Thanks for looking into it tho

[astral crown]

I'm not too sure if i follow here

[gloomy chasm]

stringValueProperty.stringValue = EditorGUI.TextField(stringValueRect, new GUIContent("").ToString(), stringValueProperty.stringValue);

[astral crown]

AAAAH

[gloomy chasm]

Or

 stringValueProperty.stringValue = EditorGUI.TextField(stringValueRect, stringValueProperty.stringValue);

[astral crown]

Wow!!!!! Thanks! I learnt from that!

[whole steppe]

How can we access Tool Settings from our editor tools?

[waxen sandal]

Reflection

I think you can find some stuff in the SceneView class using reflection

But check the reference source

[whole steppe]

They should have a simple way to access this kind of stuff atleast 😫

[gloomy chasm]

Do you mean the pivot and local values?

Hey guys. I have the following code to create an eazy to edit piece placement for a chess game I'm building. But for now I can't edit the content of the field. Am I missing something ?

[CustomEditor(typeof(PiecePlacementSO))]
public class PiecePlacementSOEditor : Editor
{

    int gridSize = 8;
    int spacing = 5;
    int labelOffset = -50;
    Vector2 cellDims = new Vector2(45, 40);
    Vector2 labelDims = new Vector2(45, 40);
    ChesspieceSO[,] tiles;

    private PiecePlacementSO piecePlacementFile;

    private void OnEnable()
    {
        tiles = new ChesspieceSO[gridSize, gridSize];
        piecePlacementFile = (PiecePlacementSO)target;
    }

    public override void OnInspectorGUI()
    {
        base.OnInspectorGUI();
        EditorGUILayout.BeginVertical();
        EditorGUILayout.Space(10);
        EditorGUILayout.LabelField("PiecePlacement", EditorStyles.boldLabel);

        for (int i = 0; i < gridSize; i++)
        {
            EditorGUILayout.BeginHorizontal();

            for (int j = 0; j < gridSize; j++)
            {
                string tileName = (char)('A' + j) + (gridSize - i).ToString();
                Rect labelField = GUILayoutUtility.GetRect(labelDims.x, labelDims.x, labelDims.y, labelDims.y, GUILayout.ExpandWidth(false));
                EditorGUI.LabelField(labelField, tileName);
                EditorGUILayout.Space(labelOffset);

                Rect boxRect = GUILayoutUtility.GetRect(cellDims.x, cellDims.x, cellDims.y, cellDims.y, GUILayout.ExpandWidth(false));
                tiles[i, j] = (ChesspieceSO)EditorGUI.ObjectField(boxRect, "", tiles[i, j], typeof(ChesspieceSO), false);
                EditorGUILayout.Space(spacing);


            }

            EditorGUILayout.EndHorizontal();
            EditorGUILayout.Space(spacing);

        }
        EditorGUILayout.BeginHorizontal();
        EditorUtility.SetDirty(piecePlacementFile);

    }
}
#endif```

[short tiger]

Are you aware that piecePlacementFile is never modified, meaning the tiles array will be lost as soon as you select another object in the editor?

[worldly echo]

I know that yeah ^^ the problem is I can’t even put something in the objectfield :/

Also if you see some nonsense please do let me know, i only started working with custom editor today x)

[short tiger]

Does it let you pick an object, but then it doesn't get assigned when you select one?

You have EditorGUILayout.BeginHorizontal(); at the end, which should be EditorGUILayout.EndVertical();

[worldly echo]

It does not :/

[short tiger]

So you can't open the object selection menu by clicking the circle?

[worldly echo]

Nope :/

[short tiger]

Ok, then it's likely an issue with the Rects

Something is wrong that is messing with the cursor interaction

Maybe negative scale or overlapping rects.

[errant shale]

• Experimenting with my first custom editor window and i struggle to find a list of all built-in visual elements. Is there any?

[peak bloom]

https://docs.unity3d.com/ScriptReference/UnityEditor.html

on the left navigation tab, choose UnityEditor.UIElements -> Classes

enjoy 🙂

[gloomy chasm]

Also there is this
https://www.foundations.unity.com/components

[worldly echo]

It was indeed, i didn’t thought about that ! Thanks a lot 🙂

[errant shale]

• This might be dumb but i struggle to add a horizontal line like those in default inspectors in creategui method, i.e. add it to a visual element. Whatever i google it involves different methods than creategui, and i'm not ready for different ways yet. I discovered this topic literally four hours ago

[gloomy chasm]

Just style the visual element
For example

element.style.height = 2;
element.style.backgroundColor = Color.black;
element.style.flexGrow = 1;

(You can also use a uss file to style it of course)

[errant shale]

• I saw uss mentions twice or so. Is it related to ui builder?

[gloomy chasm]

Or if you have a element that is containing controls that you want it below

containerElement.style.borderBottomWidth = 2;
containerElement.style.borderBottomColor = Color.black;

[gloomy chasm]

Uss is also called a stylesheet. You can use it to style elements (color, alignment, layout direction, padding, margin, border, text size, etc.) based on rules.

[errant shale]

• Cool. Now i have a custom window to see all scripts in my project as a list and their content to the right. A slightly changed script from the manual, but first steps are always tiny. I'm very excited to see what opportunities do these editors open, expect me to come here frequently 😄

[unborn wagon]

I have a problem with my custom editor. In the UI Builder all looks fine. I have a SplitView that has shrink = 1 & grow = 1. However when opening the editor outside of the UI Builder the SplitView is not expanding vertically. I checked the debugger and it shows me a TemplateContainer whichs height is set to 21 while the parent VisualElement has a height of 594. I never added that TemplateContainer. How can I get rid of it or at least force it's height to match the parent VisualElement?

[gloomy chasm]

When you create a VisualElement tree from a UXML it puts them all in to a TemplateContainer element unless you specify a parent VisualElement

[unborn wagon]

Ok so the solution is to pack everything into a VisualElement?

[unborn wagon]

I did add a VisualElement but it isn't helping. It seems that Toolbar and SplitView only work with fixed height values instead of auto.

OK I fixed it by adding VisualElement.StretchToParentSize. It seems that in the UI Builder this is done implicitly but not outside of it.

        // Import UXML
        var visualTree = AssetDatabase.LoadAssetAtPath<VisualTreeAsset>("Assets/Editor/CraftingHierarchyEditor.uxml");
        VisualElement editor = visualTree.Instantiate();
        editor.StretchToParentSize();
        root.Add(editor);

[whole steppe]

Sorry to ping you, but is there a way to make our transform handles use the pivot rotation properly

I tried this but the problem I run into is that the rot variable is returning the full rotation each time so the object keeps on turning when I move the mouse

Just to clarify, if I have the rotation handle turned to 45 deg last frame then according to my I have already rotated the object by 45 deg but I move the handle to 44 deg next frame then instead of rotating -1 deg it will multiply the rotation by 44 deg again

There is no way to have a delayed handle like we delayed fields in the inspector afaik

[peak bloom]

you can

visualElement.style.width = new StyleLength(new Length(value, LengthUnit.Percent));

[worldly echo]

Hey guys. I have the following code to create an eazy to edit piece placement for a chess game I'm building. But my tiles and my dictionnary are getting cleared everytime I enter playmode 😦 Did I do something wrong ? (code in thread)

[unborn wagon]

Short Question: https://github.com/alelievr/NodeGraphProcessor
Is this still "cool" ? I am quite new to Unity and all the fancy things I discover often are outdated. Just want to be sure to jump on the right train here.

[short tiger]

It was cool, back when it was maintained and GraphView was actively being developed by Unity. Now Unity it working to replace GraphView with GraphTools Foundation (GTF), but it's still probably at least a year until they release a public API. The developer of this package (who also works at Unity, btw) has said they want to migrate over to GTF when it's released, so maybe we'll see that.
https://github.com/alelievr/NodeGraphProcessor/issues/188

[unborn wagon]

Ok about GTF - is this already usable as preview/experimental? Cause I kinda am struggling with thee current Experimental.GraphView API 🫠

[tepid roost]

yeah i am just carrying on using graphview for now

[short tiger]

I think there's an old preview package somewhere, but it's out of date. All development for GTF is now internal, AFAIK.

[tepid roost]

no point using something more unstable and missing parts because it might be the future

[unborn wagon]

also true

[tepid roost]

if i have to make a new editor that needs something like this in the future will evaluate the options then, but its not like GraphView will disappear all of a sudden

[peak bloom]

GraphView deprecation won't happen soon, like tons of Unity's editor tools rely on that... GraphView is much better than GTF currently...

I tried both, GTF apis are a giant mess (based on their released package)

[lone halo]

Q: Does OnPostprocessModel in AssetPostprocessor not work on update? It doesn't trigger when I import FBX files the first time, but then when I overwrite them it runs.

[slender meteor]

Is there a way to make Unity install a custom package (as in menubar Assets->ImportPackage->CustomPackage) or add a package from git url (via Package Manager) from an externall app, lets say a bat file.
We can assume UnityEditor is running and platform is Windows

[waxen sandal]

IIRC there's a commandline option to import them but don't think you can do it while running without setting up your own cross process communication

[glacial notch]

not sure if this is the place, but is there a way to configure lists in the inspector to assign children of an object that has a specific component or script attatched to them?
I have this tile based system with walls, and its such a pain to extend every object and drag in the ceiling lights I want to assign to a list lol

[surreal torrent]

Is it possible to hide variables within a class object using a custom editor? Hide in terms of either not showing or at least grey it out so its not editable.

Because it is a variable inside a class object variable, I can't just not draw it if a variable is false. I think so anyways.

[slender meteor]

https://docs.unity3d.com/ScriptReference/HideInInspector.html

[whole steppe]

Anyone?

[surreal torrent]

Through custom editor on a conditional basis.

I can't change attributes after initialization and I can't not draw it due to it being in a nested class and I draw the whole top level class at once.

[waxen sandal]

So you're doing DrawEditor and then want to hide things?

Your only options are to draw the fields yourself or add properties on the Editor instance that you can manipulate to show/hide fields

[tight pine]

Hey good ppl!! 🙂 Is there a nice way to run some code on the editor every x seconds without having to depend on the EditorCoroutines package? (like for an auto-save function)

[waxen sandal]

Editor update?

[tight pine]

ho.... of course 🤦🏻‍♂️

🙂

thanks a lot

[tight pine]

That worked perfect of course 🙂

[unborn wagon]

Hey people!
I have a problem when loading assets via AssetDatabase. See on the left side there is an asset called Foo under Assets/Crafting/Recipes. So it does exist.

When debugging the code and breakpointing @ line 38 I check the result of recipes which is 0 and therefore empty. However when I also evaluate manually in my IDE (Rider) I can see that the logic actually works and yields a value?

What am I missing here? Do I need to refresh anything? It seems the editor does not know about the assets when launching.

[unborn wagon]

ah f*** nevermind I had an additional $ in the filter string of FindAssets 🫠

[whole steppe]

Could use the [ContextMenu("")] Attribute that is over a function thet just sets the list to be the result of GetComponentsInChildren

makes a button show when you right click on the component

[glacial notch]

right, but its not possible doing it automatically like unity does for you?

[surreal torrent]

I am setting a propertyfield OnInspectorGUI().

But that initializes the entire set of nested classes within including my weapon stats.

[unborn wagon]

I am really going nuts with GraphView Nodes. I simply want to have a listener when another node creates and edge to my target node. I tried this:

            input.AddManipulator(new EdgeConnector<Edge>(new EdgeListener()
            {
                OnConnectedEvent = (_, _) => { Debug.Log("Connected"); }
            }));

However it only works if my target node creates an edge towards another node. But I'd also like to listen if another node connects to my target node. Any idea for that? Just can't find anything browsing through the library

[gloomy chasm]

When you mean when a node connects to it vs it connect to a node. Do you mean input/output port. Or do you mean from where the connection action starts in the editor?

[dark roost]

Hello all! This is related to UI Toolkit, but I think the main issue is a bit more fundamental. I have commented what I am trying to do in the Inspect method (near the bottom) of the following code... I'm missing something super simple and can't find the search terms to figure it out:

{
    public new class UxmlFactory : UxmlFactory<MapEditorBlackboardVisualElement, UxmlTraits> { }

    public new class UxmlTraits : VisualElement.UxmlTraits
    {
        public override IEnumerable<UxmlChildElementDescription> uxmlChildElementsDescription
        {
            get { yield break; }
        }

        public override void Init(VisualElement ve, IUxmlAttributes bag, CreationContext cc)
        {
            base.Init(ve, bag, cc);
            var ate = ve as MapEditorBlackboardVisualElement;

            VisualTreeAsset vt = Resources.Load<VisualTreeAsset>("UXML/MapEditorBlackboard");
            ve.Add(vt.CloneTree().Children().First());

            MapEditorBlackboardVisualElement blackboardVE = ve as MapEditorBlackboardVisualElement;
            if (blackboardVE != null)
            {
                blackboardVE._selectionScrollView = ve.Q<ScrollView>("SelectionScrollView");
            }
        }
    }

    ScrollView _selectionScrollView;
    IMapEditorClickInspector _inspectorTarget;

    public void Inspect(IMapEditorClickInspector inspectableVE)
    {
        _inspectorTarget = inspectableVE;

        VisualElement target = _inspectorTarget.GetVisualElement();
        
        MapTileVisualElement mapTileVE = target as MapTileVisualElement;
        if (mapTileVE != null)
        {
            Debug.Log($"Inspecting {mapTileVE.tileNode.locationName}");
            _selectionScrollView.Add(); // Trying to populate with the default editor for mapTileVE.tileNode here
        }
    }
}```

Edit: For context, this is an inspector inside a custom EditorWindow.  I'm trying to fill its ScrollView with the default custom editor for a known class.

[dark roost]

Everything here is boilerplate for building custom VisualElements for UI Toolkit and all code works as intended. It's just the last line where I'm trying to supply _selectionScrollView.Add() with a parameter, but I'm not sure what the correct way to pull in the default inspector is.

The Debug.Log immediately before it is getting reached exactly when it is supposed to be.

[gloomy chasm]

IIRC https://docs.unity3d.com/ScriptReference/UIElements.InspectorElement.html

[dark roost]

Oh interesting. I had no idea that UI Toolkit had a tool for that. Thanks for sending this!

[dark roost]

Thanks for the help so far here. Next up, I'm not really sure how I should be handling how the InspectorElement draws. You can see from the following screenshots that I have some things set up properly, but I'm not sure yet how to make the element useable.

Code that draws the InspectorElement:

    {
        _inspectorTarget = inspectableVE;

        VisualElement target = _inspectorTarget.GetVisualElement();
        
        MapTileVisualElement mapTileVE = target as MapTileVisualElement;
        if (mapTileVE != null)
        {
            Debug.Log($"Inspecting {mapTileVE.tileNode.locationName}");

            InspectorElement inspectorElement = new InspectorElement(new SerializedObject(mapTileVE.tileNode));

            inspectorElement.style.flexGrow = 1;
            inspectorElement.style.flexShrink = 1;
            inspectorElement.style.alignSelf = new StyleEnum<Align>(Align.Stretch);
            inspectorElement.style.display = new StyleEnum<DisplayStyle>(DisplayStyle.Flex);

            _selectionScrollView.Clear();
            _selectionScrollView.Add(inspectorElement); // Trying to populate with the default editor for mapTileVE.tileNode here
        }
    }```

[peak bloom]

There's another way to detect edges one frame before they are created

     SubScribe() {graphViewChanged = OnGraphChange;     }
 
     private GraphViewChange OnGraphChange(GraphViewChange change)
     {
         if (change.edgesToCreate != null) 
          {
             foreach (Edge edge in change.edgesToCreate)
             {
                 //Your code here to process the edge
             }
         }
          //Do the same with nodes here
      }

you can do the same with nodes etc... basically all graphviewElement

this way you can check/validate which edges will be connected to which port pretty easily

it's less messy than adding custom callbacks to individual port imho

[unborn wagon]

Ok thanks I will try that out!

[unborn wagon]

@peak bloom
Hey I have an issue figuring out where I can add a handler to the GraphViewChanged event. I am in my custom GraphView class. Looking through overrides and such but can't find anything called GraphViewChanged etc.

[unborn wagon]

nevermind I just found it...

[dark roost]

Shameless plug. 😦

[peak bloom]

The docs for this is pretty much non-existent -> https://docs.unity3d.com/ScriptReference/Experimental.GraphView.GraphViewToolWindow.OnGraphViewChanged.html

just use code completion to see what the api can do

so basically you can just get the nodes without getting those edges and check which out-port match with the in-port of the node during while the edge being created the next frame

[unborn wagon]

Yeah I did that now and it works - for connections so to say. But if an edge is removed I couldn't figure a way out to hook onto that.
Because when I check change.elementsToRemove I receive the Edge that has been removed but since it has been removed it has no input or output. However I have to keep track of nodes connecting and disconnected to my target node so I can update a state according to these changes.

So I managed now to update the state when a new edge connection appears thanks to change.edgesToCreate. @peak bloom thanks for that so far.
However now I need to check if an edge has been disconnected but also from what output the edge became disconnected from - so I can remove that output's node data from my state.

The most annoying this is this:

    internal Action<Port> OnConnect;
    internal Action<Port> OnDisconnect;

These are callbacks I can register on Port. However they are internal cmon guys listening to a port connection is quite a use-case for a node-graph imho.

Well I will continue crawling through the API to find a way 😄

[peak bloom]

then you can make custom Port class derives from Port then override these two @unborn wagon

              //I sorta forget if this is correct, you should check
              public void OnDropOutsidePort(Edge edge, Vector2 position)
              {
              }
       
              //This one pretty sure it's the correct one :)
              public void OnDrop(GraphView graphView, Edge edge)
              {
              }

And cache the connected nodes somewhere or to scriptable asset...
I forget if this was documented at all... at least something along those lines

for Connect and Disconnect you can do this for Ports as well, no need to do it via edges/nodes and they both are public there

...

All and all, just do it you logic in the Port ..you can handle both edges & nodes there pretty easily

[gloomy chasm]

Ehh, I think there is a bug in the version of Unity you are on. Try checking it in the debugger, I think you will see the actual fields on the far right side.

[plush mulch]

Hi, I'm wondering if there's a way to get custom input fields? I need to access my animations in a custom window.

[waxen sandal]

What?

[plush mulch]

I have to make myself a tool that edits animations in a way. However I need an input field method to allow me to even select a different data type

[grand robin]

Hello people, does anyone knows a easy way to make the interface in this function a popup like in the image?

public static void ValueChangerMaker(SerializableDictionary<string, float> objArray, string name,
out SerializableDictionary<string, float> newObjArray)
{
newObjArray = new SerializableDictionary<string, float>();
KeyValuePair<string, float>[] objArraySolver = objArray.ToArray();
KeyValuePair<string, float>[] newObjArrayReturner = new KeyValuePair<string, float>[EditorGUILayout.IntField(name + " length", objArraySolver.Length)];

    for (int x = 0; x < newObjArrayReturner.Length; x++)
    {
        EditorGUILayout.BeginHorizontal();
        if (x < objArraySolver.Length)
        {
            string[] split = objArraySolver[x].Key.Split('_');
            EditorLists_Script.affectableValues keyValueAffected = EditorLists_Script.GetAffectableValue(split[0]);
            EditorLists_Script.affectableValues keyValueBasedOn = EditorLists_Script.GetAffectableValue(split[1]);
            newObjArrayReturner[x] = new KeyValuePair<string, float>(EditorGUILayout.EnumPopup("Affected " + x, keyValueAffected).ToString() + "_" 
                + EditorGUILayout.EnumPopup("BasedOn " + x, keyValueBasedOn).ToString(), EditorGUILayout.FloatField("Value " + x, objArraySolver[x].Value));
        }
        else
        {
            EditorLists_Script.affectableValues keyValue = 0;
            newObjArrayReturner[x] = new KeyValuePair<string, float>(keyValue.ToString() + "_"
                + keyValue.ToString(), 0);
        };
        EditorGUILayout.EndHorizontal();
    }
    foreach(KeyValuePair<string, float> pair in newObjArrayReturner)
    {
        newObjArray.Add(pair.Key, pair.Value);
    }
}

[plush mulch]

Anyway with my issue, there's no field type that accepts custom fields

[unborn wagon]

format your code with ```cs

[unborn wagon]

I have a weird issue with created/saved assets.
When working in my custom editor I create and save assets this way:

AssetDatabase.CreateAsset(recipe, $"{_path}/{recipe.RecipeName}.asset");
AssetDatabase.SaveAssets();

When closing the Editor and reopening I load the assets this way:

        public static List<CraftingRecipe> Load()
        {
            var recipes = AssetDatabase
                .FindAssets($"t:{nameof(CraftingRecipe)}", new[] { _path })
                .Select(AssetDatabase.GUIDToAssetPath)
                .Select(AssetDatabase.LoadAssetAtPath<CraftingRecipe>)
                .ToList();
            return recipes;
        }

The weird part

• When I keep Unity open and close/reopen my custom editor it all works fine. The assets are loaded properly including their properties which are also ScriptableObjects.
• When I close Unity and reopen it and then open my custom editor the assets are only loaded shallow having null assignments for the mentioned properties this time.

So for some reason when I close Unity the assets aren't really saved. Does that mean that the asset properties are kept in Unity's memory as long as I have it open and are discarded as soon as I close Unity?

Do I save the assets in a wrong way? It seems that serialization is not applied to properties of type ScriptableObject ?

A bit more investigation. The Asset kinda changed from an instance to the base object. As you can see the ID changed from -2812 to 32704 and lost the Receipt Name property value

[grand robin]

what is " '''cs"

[grand robin]

I had a simillar problem and can be many things, first, Lists and Dictionaries do cannot be used to save values modified in inspector if they aren't serialized, and unlike structs you can't simply put [Serialize] to solve that, you need to create a custom script that serializes the thing for you

[unborn wagon]

CSharp code formatting for discord

[grand robin]

the second thing is that at the end of the code that is controlling the inspector you might need to put
EditorUtility.SetDirty(controller);
serializedObject.ApplyModifiedProperties();

[grand robin]

ohhh

[unborn wagon]

Ok good point! Well I just realised I don't need assets in that case anyway. Just was curious how the creation worked. I will go use native JSON serialization

[gloomy chasm]

Uhh, there is a lot to unpack here. The main thing would be, how are you setting the values before saving?

[gloomy chasm]

The instance ID of an object is based on the order that it is loaded in. negative numbers are for objects in memory and positive are for objects saved on disk.

[gloomy chasm]

You don't need to do SetDirty on the object if you are using SerializedObject. And you should not be setting values with both SerializedObject and directly. That is a big no, no as it is likely you would lose data and get unexpected values. Also it is just messy.

[unborn wagon]

Ahh ok interesting

[unborn wagon]

I guess I will make a small test case to fully understand how the saving works 😅

[plush mulch]

I'm still wondering if there's a way to make custom field entries.

[waxen sandal]

You can make custom controls to do whatever you want but what you want isn't easy to explain

[plush mulch]

That's why I'm asking in the first place?
I've been looking for over 6 hours last night for a single answer. Even for a generic use, I can't find a post or documentation that has any explanation.

We program solutions to our problems. This means even having to make complex code in order to make infinitely simpler workflow.
In my case: I'd be forced to make unusual functions both blindly and painstakingly by hand without the tool I'm trying to make.

[waxen sandal]

This blog series might have relevant info for you http://leahayes.co.uk/2015/08/25/custom-editor-controls-in-unity-part-2.html

[peak bloom]

(After reading that) should be much easier in uitk I think

[earnest talon]

It is possible, just the means of which to do so is... hazy sometimes

You'd have to account for every field type if it's using generic types

(e.g. Serialized Property value and you want a generic, reusable method)

or you'd have to make sure nothing that isn't your specific object type/class can't get through the method.

[vast isle]

    public class AbilityEditor : PropertyDrawer
    {
        public override VisualElement CreatePropertyGUI(SerializedProperty property)
        {
            
            return base.CreatePropertyGUI(property);
        }
        
    } ``` I am trying to show abstract class in scriptable object but I get this (No GUI Implemented ) any ideas?

[visual stag]

your drawer is doing absolutely nothing, so what's unexpected about that?

[vast isle]

the base class has public float it should show it in inspector?

[visual stag]

what is this AbilityEditor drawer doing? Your method does nothing

[vast isle]

return base.CreatePropertyGUI(property); should show default inspector right?

[visual stag]

No

[vast isle]

hmm then I am doing something wrong I will research property drawer more ty for info

[visual stag]

The default drawer is no drawer, so if you implement it and just call the base method, that method just draws No GUI Implemented, because it's the same as just writing:

[CustomPropertyDrawer(typeof(Ability),true)]
public class AbilityEditor : PropertyDrawer {}```
If you want to draw what the default GUI does, then that's just a PropertyField

[dreamy viper]

Hi,
By default, the packages downloaded from the Asset Store are saved in C:/Users/%USER%/AppData/Roaming/Unity/Asset Store-5.x
How can I retrieve this path by code?
(I want to use this path with AssetDatabase.ImportPackage)

[vast isle]

Ty its working now

hmm still showing No GUI Implemented Scriptable object don't know why

[visual stag]

Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), "Unity\\Asset Store-5.x")

[dreamy viper]

It works, thank you for your quick answer.

[vast isle]

I just create new scriptable object and its working now TY For taking time to help

[frail sage]

hey all, I tried to extend a button but the Normal Color on the button isn't working not sure what I did wrong here. Any Ideas?

[frail sage]

how do you remove a property from the inspector?

[atomic sable]

[HideInInspector] I believe

[astral crown]

idk what I should do, I'm having some problem and I'm limited in knowledge about this:

#if UNITY_EDITOR
[CustomPropertyDrawer(typeof(EnumPieceCoord))]
public class EnumPieceCoordDrawer : PropertyDrawer
{
        // private int selectedOptionIndex = 0;
    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        EditorGUI.BeginProperty(position, label, property);
        int index = int.Parse(property.propertyPath.Split('[', ']')[1]) + 1;
        position = EditorGUI.PrefixLabel(position, new GUIContent("Pièce " + index));

        int indent = EditorGUI.indentLevel;
        EditorGUI.indentLevel = 0;

        Rect enumRect = new Rect(position.x, position.y, position.width / 1.2f, position.height);
        Rect stringValueRect = new Rect(position.x + position.width / 1.2f, position.y, position.width / 5 - 5, position.height);

        SerializedProperty enumProperty = property.FindPropertyRelative("typePiece");
        SerializedProperty stringValueProperty = property.FindPropertyRelative("coordonner");

        string[] enumNames = Enum.GetNames(typeof(DonnéePièces.TypePièce));
        int selectedOptionIndex = Array.IndexOf(enumNames, enumNames[enumProperty.enumValueIndex]);

        enumProperty.enumValueIndex = EditorGUI.Popup(enumRect, selectedOptionIndex, enumNames);
        stringValueProperty.stringValue = EditorGUI.TextField(stringValueRect, stringValueProperty.stringValue);

        EditorGUI.indentLevel = indent;
        EditorGUI.EndProperty();
    }
}
#endif

My EnumPiece is a List inside a variable named Equipe and I made a array: Equipe[] field in my script. When it's not a array it's working as intended but when it's in array it makes my element called the same number (Piece 1,1,1,1 / Piece 2,2,2,2, etc)

Do I need to make a new Drawer from Equipe? or something?

[astral crown]

Rect sizeRect = new Rect(position.x, labelRect.yMax, position.width, EditorGUIUtility.singleLineHeight);
        EditorGUI.PropertyField(sizeRect, listProperty);

        // Show the elements of the list
        Rect elementRect = new Rect(position.x, sizeRect.yMax, position.width, EditorGUIUtility.singleLineHeight);
        for (int i = 0; i < listProperty.arraySize; i++)
        {
            SerializedProperty elementProperty = listProperty.GetArrayElementAtIndex(i);
            float elementHeight = EditorGUI.GetPropertyHeight(elementProperty);
            elementRect.height = elementHeight;
            EditorGUI.PropertyField(elementRect, elementProperty, true);
            elementRect.y += elementHeight + EditorGUIUtility.standardVerticalSpacing * 2;
        }

        EditorGUI.indentLevel = indent;
        EditorGUI.EndProperty();

I tried to make a property of a list but my elements are on top of each other. I decided to try from scratch on Equipe

Sadly I'm getting this

[visual stag]

https://help.vertx.xyz/programming/editor-issues/property-drawers/getpropertyheight

[dark roost]

Thanks for the reply! In the debugger, those fields appeared as a single IMGUI element, I believe. I'll take a look at it again tonight.

[astral crown]

Alright... I think Im getting close to understand the use of GetPropertyheight

Some errors are still there and are weird tho (like my button Rouge being clickable everywhere in the same column area lol)

[visual stag]

You must not have set the height of that control properly then

[atomic sable]

How in the world does a GUIStyle control the outline color while hovering? I'm convinced there must be some hidden behavior we can't see. Look at GUI.skin.textField as an example. When hovering over a box drawn with that style, the outline will be highlighted white. Yet I cannot figure out for the life of me what causes that. Is it GUIStyle.hover or GUIStyle.onHover? no. Those don't even have that many fields that could modify anything to cause that, except the image, which doesn't do that because the image is the same as the GUIStyle.normal and GUIStyle.onNormal one. So how does it do it?

[visual stag]

I imagine it's handled internally using something more global like the StylePainter class

None of which can be overridden

Luckily the advisable way to create editor UI is UIToolkit, where it's all just very clear stylesheets for the most part

[atomic sable]

hmm, well it's a bit too late to use the UIToolkit for me. Maybe next project.

[barren plinth]

idk what happened but after re-enabling gizmos my editor started works bad

ok, i just pushed F and everything is solved

[hoary grove]

Anyone know how to create a Prefab Variant via a Menu Item?

[MenuItem("My Menu/Create Arena")]
    static void CreateArenaVariantPrefab() {
        Object source = Resources.Load("Assets/Prefabs/_Arenas/_Shared/Base_Arena.prefab");
        GameObject objSource = (GameObject)PrefabUtility.InstantiatePrefab(source);
        GameObject obj = PrefabUtility.SaveAsPrefabAsset(objSource, "Assets/Prefabs/_Arenas/_New/NewArena.prefab");
    }

Is my current setup, however, no luck.

Better yet, how would I also go about prompting the user for new name?

[dreamy yarrow]

Whats a good place to get started if i know NOTHING about editor extensions

[arctic jolt]

1. following a tutorial on youtube or somewhere
2. copying stuff from unity docs and learning from there
3. downloading some free assets in the asset store that have editor extensions in them, and analysing their code, ideally new and small ones

[simple cove]

imo just start making a simple editor extension and google every step you need to get there

[simple cove]

for the new name, you can create open a new editor window that has a single field and a button, and initialize its 'button' function, like so:

EditorWindow.GetWindow<StringFieldInputter>().Initialize(Title: "Enter name", fieldName: "New Name:", onConfirm: () => { PrefabUtility.SavePrefabAsset(...); });

public class StringFieldInputter : EditorWindow {
    System.Action onConfirm;
    string fieldName;

    public void Initialize(string Title, string fieldName, System.Action onConfirm) {
        this.Title = Title;
        this.fieldName = fieldName;
        this.onConfirm = onConfirm;
    }

    void OnGUI() {
        //..render field
        //..render button, have it invoke OnConfirm when pressed
    }
}

[placid rune]

not sure if this is where to go, (i have no idea how to do editor scripting) but how would i go across getting the value of an enum and changing the values you can change?

for example:

if you choose the weapon type "AR" it would only show up the customization for an AR
if you choose the weapon type "Sniper" it would only show up the customization for a Sniper
etc etc.

[atomic flower]

Enums render as dropdown selection by default

[placid rune]

i'm confused, i know that, but i was wondering if i can get what is chosen from the dropdown and use that to determine what values are shown in the script

[atomic flower]

It's difficult to tell you exactly what to do without knowing more about your architecture, but idea would be to have a script with a SerializedField of type YourWeaponEnum. Reference this in Update() or read it from another script.

[gloomy chasm]

IIRC it is literally just a different texture. Basically all IMGUI drawing is done via textures. So the text box with a highlighted border? Yup, that is literally a texture of a text field with the border pixels changed.

[gloomy chasm]

That should work as far as I know

[hoary grove]

Yeah I got it mostly working now with this:

[MenuItem("Kage Menu/Create Arena")]
    static void CreateArenaVariantPrefab() {
        Object originalPrefab = (GameObject)AssetDatabase.LoadAssetAtPath("Assets/Prefabs/_Arenas/_Shared/Base_Arena.prefab", typeof(GameObject));
        GameObject objSource = PrefabUtility.InstantiatePrefab(originalPrefab) as GameObject;

        var allNewLevels = Resources.LoadAll("Assets/Prefabs/_Arenas/_New/");
        float count = allNewLevels.Length;
        GameObject prefabVariant = PrefabUtility.SaveAsPrefabAsset(objSource, "Assets/Prefabs/_Arenas/_New/New_" + count + ".prefab");

        DestroyImmediate(objSource);
    }

However, my count isnt working properly.

[gloomy chasm]

AssetDatabase.GenerateUniqueAssetPath() 😉

[hoary grove]

Perfect.

[gloomy chasm]

Also it wasn't working because Resources.Load only works for things that are in a Resources folder, and the path is relative to it.

[hoary grove]

Thats what I figured. But also Google was telling me otherwise for some reason.

[atomic sable]

but I can't find that texture at all. I tried setting the normal texture to the hover texture, the onNormal texture to the onHover texture, the normal texture to the onHover texture, and the onNormal texture to the hover texture.... is there another texture it could be using?

[atomic flower]

I have a SerializeReference field with a serialized list that I'm trying to update in the editor. I call serializedProperty.serializedObject.ApplyModifiedProperties(), but it's not updating. Is there some different way to update a managed reference value to just a serialized property?

[unborn wagon]

How can I clear a Textfield - text property? I want to reset it after the value has been submitted in my editor. However text is readonly.

[rotund lava]

Hi all, question about vertical layout boxes - is there a way to make them look more like the ones used to display lists?
Alternatively, is there a way to replicate the default list graphic?

[gloomy chasm]

I assume you mean UIToolkit, textField.value

[gloomy chasm]

I assume you mean using IMGUI, in which case, yes, it is called ReorderableList

[rotund lava]

Ah cool, thank you!

[sharp rune]

Hey, is anyone familiar with the Hot Reload package?

I am using it on Unity 2019.3.5f1
In this older version of unity, the setting for auto refresh to turn off during play mode does not exist. Auto refresh only has a true or false state.

I find this annoying to manage with hot reload cause it means I constantly have to press Ctrl+R to get any asset folder or script changes made while not in play mode.

So I wrote a script that turns auto refresh off when I click the play button (before play mode is even set to true)

however, this seems to just break hot reload... it no longer catches any of my script changes in play mode, even if I ctrl+R while playing

Anyone know whats going on here or how I can fix this? I just want auto refresh automatically on during edit mode, but turned off for play mode so hotreload can function properly

[gloomy chasm]

I would contact support for the Hot Reload package, as it sounds like either a bug or a lack of documentation on their part. Generally people here don't really help with 3rd party specific things as it is best left up to those specific communities or support channels.

(unless there is a Unity created hot reload package which you are referring to that I am not familiar with)

[sharp rune]

no, its third party

I'm just not understand why this is breaking hot reload, it should be no different than me manually turning off auto refresh then clicking play, in which case hot reload works normally

unless there is some sort of timing issue here, and doing the auto refresh false on if (EditorApplication.isPlayingOrWillChangePlaymode && !EditorApplication.isPlaying) is not early enough to not mess with hot reload

[gloomy chasm]

Again, no idea. Would really recommend reaching out to support for the package since it is pretty specific to that package

[sharp rune]

actually I did a bit of debugging and realized its not a hot reload issue I'm having...

my script actually works when I change things in any script except for player script

something wonky is going on with ym player script.... but the error hot reload is spitting out has to do with cinemachine? I'm so confused.

[rotund lava]

Oops

meant to edit it

[gloomy chasm]

Lol, well to answer your question, assuming that you are the one showing the menu, it only has the check marks because you told it to

[rotund lava]

Yeah just found the issue as it is, thanks for taking the time lol
I'd used "true" when adding items to the menu, which obviously makes the item checkmarked :)

[gloomy chasm]

Yup

[frank garnet]

So i have an issue where i have 2 objects, i want them both to be on the same Order in layer, but i need to control which one is in front of the other. any ideas?

[grand robin]

How do I make the length between the Name and the EditableFields on the horizontalLayout a little smaller? I can't show the 3 values side by side without them getting out of the inspector view

WHYYYYYYYYYYYY?????

[visual stag]

Temporarily override EditorGUIUtility.labelWidth

[grand robin]

It worked, Thank you, kind sir

[dark roost]

Hello all - I have a very generic question as I'm looking for a starting point. I'm looking to take a whole lot of ScriptableObjects which live in my project folder and pack them into a smaller number of assets - namely a "map file". I've seen this before, but all searches seem to be pointing me to pages of search engine results on prefabs.

[latent tiger]

When you say 'pack', what do you mean by that?

[dark roost]

As I understand, there is a way to add a serialized object to an existing asset file?

[latent tiger]

Ah. Yes, there is.
https://docs.unity3d.com/ScriptReference/AssetDatabase.AddObjectToAsset.html

However, I believe that if the object in question already exists as an asset in your project (saved on disk), it cannot be added to the other object

[dark roost]

That interesting to know; and also tells me something new about how serialized objects are referenced. That's actually desirable in my case. Thanks for pointing to that method for me! @latent tiger

[latent tiger]

👍
If you need to 'reparent' your existing ScriptableObjects into a MapScriptable object, you can Instantiate a copy of the existing ScriptableObjects, and then use AddToAsset to the Map.
Of course, that won't shift the references to the new Instances, but at least it may save you the work of inputing whatever data you've already setup in your scriptable objects.

[dark roost]

I appreciate that. At this moment I don't have any data that I really need to save as my "map editor" isn't ready for designers anyway, but that's the way I think I would do it.

Wow, AssetDatabase is very useful in general.

[latent tiger]

Mhm. There's plenty of good stuff in there.
I'd also tell you to take a look at PrefabUtility, as well as EditorUtilities for some other useful things.

[dark roost]

So if I understand the anatomy of an asset file, there is always one main asset and then numerous sub-assets that are parented to it.

[latent tiger]

I've recently discovered an easy check to see if the object is persistent in EditorUtiltiies.IsPersistent, instead of checking the path using asset database 🛌

Yes.

AssetDatabase contains functions for IsMainAsset and IsSubAsset

[dark roost]

That's actually very useful as I have a sort of dynamic dictionary that holds onto design-time values used for other scripts and it would be useful to know what lives within the lifetime of the game and what persists on disk!

[dark roost]

    {
        _inspectorTarget = inspectableVE;

        VisualElement target = _inspectorTarget.GetVisualElement();

        MapTileVisualElement mapTileVE = target as MapTileVisualElement;
        if (mapTileVE != null)
        {
            Debug.Log($"Inspecting {mapTileVE.tileNode.locationName}");

            InspectorElement selectionInspector = new InspectorElement(new SerializedObject(mapTileVE.tileNode));
            
            selectionInspector.style.width = 100f; // Trying stuff here
            selectionInspector.style.fontSize = 9;

            _selectionScrollView.Clear();
            _selectionScrollView.Add(selectionInspector); // Trying to populate with the default editor for mapTileVE.tileNode here
        }
    }```
In this script, I am trying to modify the USS of `selectionInspector` to wrangle it's width.  The problem here is that it renders out as an IMGUIContainer of a fixed width and I'm not sure how to contain it to within the calculated width of it's parent ScrollView.  See the animation for an example.

Thanks to anybody who reads!

In the debugger, it is just an IMGUI so there is no deeper view of VisualElements within.

[astral crown]

yo this is cool!

[dark roost]

Thanks! But this veil of working on USS within a generated IMGUI is a bit of a struggle...

[astral crown]

I dont know any of those terms lol, XD I have so much to learn XD

Oh so USS is Style UI? Unity Style Sheet, I see

By the way I have a question if someone can answer me, I played a lot with override GUI. But is there a way to have a OnGUI parent not overriding it's OnGUI child? Like currently It felt way more easier to change the UI of my "Les Pieces Equipe" because trying to change "PiecesEquipes" used notion I don't understand yet. But I'm curious as how can I used the OnGUI Element inside a OnGUI?

[dark roost]

I hope I follow correctly... call public override OnGUI() { base.OnGUI(); }?

[astral crown]

Well I think so, I'll try that

[lyric oyster]

how do I design a custom VisualElement with INotifyValueChanged<T> interface that act like a Collection (with value get/set index)?

INotifyValueChanged<T> probably wouldn't be very nice for a collection as it's supposed to represent a singular modifiable field

probably would be better if I make an event myself, but I still want to hear others' opinion about this

[vast isle]

I am stuck on making Sub menu in UIElement PopupField if I do this "menu1/menu2/item" the Choice Name will be this "menu1/menu2/item" any idea ?

[tawdry kraken]

Hello. I have a script which generates another script with MenuItems and methods, based on text files in a specific folder.
I need to re-generate it whenever one of the text files are changed, or a new one is added, or any are renamed.
Is there a good reason to choose either AssetPre/PostProcessor or FileSystemWatcher?
Aiming for low performance impact.

[gloomy chasm]

You use the asset processor because the file on disk is not always the same as the in engine representation (the UnityEngine.Object) because the in engine object is not always saved after every changed made to it

[tawdry kraken]

That's a very good argument ✅

[gloomy chasm]

Also it is just the right way to do it. The Unity way. The intended way.

[tawdry kraken]

Indeed. If you feel like a dive, let me know if you have any other suggestions.

[gloomy chasm]

Firstly, what version of Unity are you on?
Secondly, you need to keep a reference to the SerializedObject you are creating because you need to call serializedObject.Dispose() on it to clean it up (I am surprised you are not getting any warnings in the console about this)

[tawdry kraken]

Some thread mentioned it disposes in the deconstructor.
I'm not an expert, but perhaps this means it's okay?
https://github.com/Unity-Technologies/UnityCsReference/blob/master/Editor/Mono/SerializedObject.bindings.cs

[gloomy chasm]

I was replying to someone else haha

[tawdry kraken]

I know, but still

I am curious, because I am not calling Dispose() on any SerializedObject* in any of my scripts 😆

Manual control is probably better anyways

[gloomy chasm]

The thing is that things are GCed at inconsistent times, so you may have them floating around in memory for a bit. So while they will at some point clean them selves up. It is much cleaner and safer to do it yourself. And just better practice.

Especially since SOs are connected to native objects.

[gloomy chasm]

Looks pretty fine. A few small notes. You can use Path.GetFileName(path) instead of doing the string stuff.
You can then do LastIndexOf('.') to see if it has a second extension.
Also, change the name of the method please to HasTwoExtensions Because if it has more you return false, so it is not "At least two" 😛

It is better to not do file creating and mess with assets in InitalizeOnLoad as those can be expensive and especially if you are generating C# files, it can get called recursively.

[unborn wagon]

I'd like to have a mesh/model preview here just like the Unity out of the box mesh preview works. Any idea how to do this? I found PreviewRenderUtility and some tutorial to this that are 5 years old. I wonder if there is a "new" way of achieving this?

[gloomy chasm]

PreviewRenderUtility is still the way.

[tawdry kraken]

Path.GetFileName - That's the one I was forgetting to use 😅
HasTwo vs HasAtLeastTwo - I'm not sure that's correct. It seems to work fine.
It returns false if there are not at least two extensions.
One of the items in the array items is the filename.

[gloomy chasm]

Oh I missed the not in the if statement. That is what I get for not paying enough attention, my bad!

[tawdry kraken]

It's barely readable. I some times write == false because of it 😆

[gloomy chasm]

ew

[tawdry kraken]

Don't hate me because I'm readable 😉

[unborn wagon]

Can anybody explain OnGUI to me? I am creating a custom editor for a while now. I stumbled across OnGUI now and the doc says Implement your own editor GUI here. I mean what does that mean? I am creating an editor GUI (graphical user interface) the whole time with the UI Toolkit am I not? I am quite confused

[shadow granite]

There's three ways to make editor GUI's

IMGUI, uGUI and UI Toolkit

OnGUI is for IMGUI (pretty sure you don't use it for UI Toolkit but i've never used UI Toolkit) (Looking briefly through the UI Toolkit docs it seems i'm right)

https://docs.unity3d.com/Manual/UIToolkits.html

[unborn wagon]

Yeah ok but what is OnGUI - it's clearly a lifecycle but when does it trigger? When the EditorWindow is launched?

[shadow granite]

i think it's a bit complicated

It can run multiple times in a frame

if you are using UI Toolkit, ignore OnGUI and follow the UI Toolkit docs

[unborn wagon]

I am checking out this Code example here: https://github.com/CyberFoxHax/Unity3D_PreviewRenderUtility_Documentation/wiki/PreviewRenderUtility

I see that CreateWindow is referenced to a MenuItem entry. It creates a window with the EditorWindow implementation. So I guess it's launched after that window is called with .Show()

[unborn wagon]

The problem is that all docs regarding PreviewRenderUtility are showing examples with OnGUI

However I need to render a 3D mesh in here

And I simply can't find any examples to that and it's quite hard to figure out

[shadow granite]

ah maybe UI toolkit can't do that yet so you have to make a hybrid system

[unborn wagon]

Well I used UI Toolkit only for layouting

I do the rest with Code

Ah wait a second. OnGUI seems to be some kind of Update. It's called frequently. Maybe I have to put drawing logic in there to properly render the thingie... 🫠

[shadow granite]

maybe

[unborn wagon]

Yeah it works now

Thanks for rubberducking 🦆

[shadow granite]

quack

[gloomy chasm]

Sure, unity has 2 ways of creating editor UI. 1 is the older way called Immediate Mode GUI (IMGUI). You use the OnGUI, and OnInspectorGUI methods for it. They are called 'every frame' (a bit more complicated than that, but that is okay).
To draw controls you use things like if (GUILayout.Button("My Button")). None of the controls have their own 'state', as in the don't store values. You can think of it sort of how the old input system works, where you would do if (Input.GetButtonDown("Attack")), and the frame the button is down, the code in the if statement runs. Same with IMGUI.

The other, new way is called UIToolkit, it is what is called a Retained Mode GUI. That means it is only created once, and the controls have their own states which they update.
You can use IMGUI inside of UITK by using a IMGUIContainer element.

UGUI is only for runtime GUI.

You can only use one of the methods as the main drawing method. Either IMGUI or UITK. Aka OnGUI or CreateGUI

[unborn wagon]

Ok I see - however for rendering that 3D Mesh I think I have to use OnGUI since it's the only way to have frequent calls it seems. CreateGUI is only called once.

[gloomy chasm]

Nope, like I just said, you can use a IMGUIContainer element to draw IMGUI inside of UIToolkit

[unborn wagon]

Ah ok right - will try that asap

[honest python]

Heyo, how would I go around making a custom inspector for class tagged with a specific attribute? I thought I could simply do something like

[WithCustomEditor]
public class SomeClass : MonoBehaviour {}

public class WithCustomEditorAttribute : Attribute {}

[CustomEditor(typeof(WithCustomEditorAttribute))]
public class WithCustomEditorAttributeEditor : Editor {
  public override OnInspectorGUI() {
    base.OnInspectorGUI();
    GUILayout.LabelField("Hello there");
  }
}

But this doesn't seems to work for me. I'm also unable to find any info about it on the web, or at least nothing that specifically focuses on how to start up custom editors using attributes.

[waxen sandal]

You can only create property drawer based on attributes

[honest python]

Oh. CustomPropertyDrawers can only target serialized object, right? Because I was hoping to make unity events triggerable basically, e.g., by adding a button to inspector. But unity events aren't serialized so I assume that won't work for them either.

[waxen sandal]

Unity events are serialized, otherwise they don't show up in the inspector

Iirc it's done using the UnityEventBase class

[whole steppe]

i install the 2d package but when i close unity its gone

[crude forge]

ah, I'll ask here. This code is causing a memory leak error, I have no idea why...

IsFoldoutComputerInfoLists[i] = EditorGUILayout.Foldout(IsFoldoutComputerInfoLists[i], "Computer " + myTarget.computerNetworkIdentityList[i].connectionId);

"A Native Collection has not been disposed, resulting in a memory leak."

[delicate path]

Anyone aware of a decently-low-effort way of adding a custom icon texture for an asset file type? I vaguely recall doing that ages ago, but can't for the life of me recall the approach. I have two scenarios to cover: One already has a custom importer and the other does not (so it just gets handled as DefaultAsset). If a solution turns out to involve setting up a custom importer, doing that for the type which currently has none works for me too.

[unborn wagon]

With my editor I want to create a very simple ScriptableObject:

    [CreateAssetMenu(fileName = "New Item", menuName = "Item Atlas/Item")]
    public class Item : ScriptableObject
    {
        public string Name { get; set; }
    }

I use this logic therefore

        public static void Create(Item item)
        {
            if (!System.IO.Directory.Exists(_path))
            {
                System.IO.Directory.CreateDirectory(_path);
            }

            var path = $"{_path}/{item.Name}.asset";
            AssetDatabase.CreateAsset(item, path);
            AssetDatabase.SaveAssets();
        }

It does save fine. The created asset has a negative instance ID that tells me (according to the documentation) that this asset is an instance. Which is right. It's an instance of Item.
However when I restart unity the asset's instance ID is positive. That does mean it's an origin object? I kinda feel that might become a problem later?

Same happens when I use the CreateAssetMenu to create the asset. At creation its ID is negative and after editor restart it's positive.

[shadow granite]

I guess it's a bit weird (assuming you checked after SaveAssets) but as long as it works fine then nothing to worry about?

[waxen sandal]

This might work https://forum.unity.com/threads/custom-asset-icons.118656/#post-2443602
Or maybe the last comment in that thread, been too long tbh since I've looked at it

[unborn wagon]

well for now it works fine. I wonder what happens when I want to load these assets and edit them again. Kinda have a feeling the changes might get lost...

[maiden vale]

you need to make sure you set the scr obj dirty after any changes done in code then everything should work out fine.

[tawdry kraken]

General question: Is it bad practice to use a folder named Editor for non-Editor folder purposes?
It's also inside a folder named Editor.

The entire thing is an editor tool. No runtime.

[amber valley]

Editor only put your code in an Editor-exclusive assembly. Good practice to put your editor tool related stuff there if you don't use custom asmdef

[latent tiger]

I have a rather beginner question related to serializedObjects and Property in a custom editor:
I have the following:

public class OpenDialogue:ScriptableObject
{
  public Dialogue dialogue;
}

public class Dialogue:ScriptableObject
{
  public int someValue;
}

[CustomEditor(typeof(OpenDialogue))]
public class OpenDialogueEditor:Editor
{
  SerializedProperty dialogueProperty;
  SerializedProperty dialogueSomeValueProperty;

  OnEnable()
  {
    dialogueProperty = serializedObject.FindProperty("dialogue");
    //How do I access "someValue" inside the dialogueProperty?
    //Do I have to create a new serialized object based on dialogueProperty.objectReferenceValue?
    dialogueSomeValueProperty = dialogueProperty.FindPropertyRelative("someValue"); //This returns null apparently
  }
}

[waxen sandal]

Since dialogue is a scriptableobject you have to create a new serialized object out of the objectreferencevalue

Then do find property on that

[latent tiger]

Ah. So any Object type reference does need a new serializedObject.
Thank you for the clarification

Worked like a charm, thank you Navi ❤️

[unborn wagon]

Ok so loading, changing, set to dirty and then SaveAssets() again?

That will make sure that the assets are properly updated

[maiden vale]

yes. this should even work if you work with instances of the scriptable object

[waxen sandal]

Yep exactly!

[delicate path]

Thanks 🙂 That is a bit rougher than what I was looking for. I dug up my old Behave project and tracked down how I did it originally with a png in /Assets/Gizmos. That only covers the case where I already have an importer though, so I guess I'm adding an importer for this other type as well.

[waxen sandal]

Ah yeah, I'm not a fan of that method since it requires specific paths

Glad you got it working though

[delicate path]

The alternative which doesn't involve editing meta files basically has the importer set a per-asset thumbnail reference which I'm also not really a fan of. At least the Gizmos approach is easily tweaked globally.

[delicate path]

This is expected behaviour.

[unborn wagon]

I used EditorUtility.SetDirty(myAsset) now as I changed the loaded asset properties. It immediatly synced the change to the original asset. Does that mean I do not have to use AssetDatabase.SaveAsset() ?

[delicate path]

SaveAssets is just a force-save-right-now instruction. It isn't required for changes to eventually be saved.

SetDirty is equivalent to Undo.RecordObject - it just notifies Unity that the object holds unsaved data. It is then up to Unity to write those changes to disk whenever it feels like. Like when something calls SaveAssets or you save your scene or enter playmode or build or a bunch of other scenarios.

But like all other changes in the editor the data definitely will get written to disk - so long as the editor does not crash before it gets a chance to do so.

[dreamy grotto]

is there a way to merge materials in play time?
like i have the path of material. i change the material at runtime then when i stop playing i want to get that material and merge the actual asset
you can do smth like this with prefabs. prefabutility.mergeprefabinstance smth like this works fine
but i couldnt make it for material
is there a way to do it?

this is the logic i guess but it does not work. any ideas?

[signal thicket]

i have a question
When devloping games do u all use JPG's for sprites or PNG's?

a 2D game specifically

oh wait this is editor extensions sorry

[stark flume]

trying to create a node-based state machine/behavior tree graph that will execute different scripts depending on different inputs. now im trying to create a field on each node that will let u assign a script (probably based on a BehaviourScript class or something). the closest ive been able to get to this is adding an ObjectField to the node, which accepts any type of object. is there any way i can have it only accept a certain type?

i can move this into a properties window or something if its not gonna work on a node, but even then ill have a similar question of how to get it working

[dark roost]

2022.2.4f1, and good to know about .Dispose();

[latent tiger]

https://docs.unity3d.com/ScriptReference/EditorGUILayout.ObjectField.html
Use the type parameter as a way of filtering out the kind of object you want.

[visual stag]

Set https://docs.unity3d.com/ScriptReference/UIElements.ObjectField-objectType.html

But you won't be able to just assign script files (well, you can, but it's not going to be useful), you'll only be able to assign prefab components

[dark roost]

@gloomy chasm My issue is solved by moving to 2023 beta ver.

[peak bloom]

Not necessarily, when you use setDirty you're also informing the editor

[peak bloom]

they're not the same, setDirty does not create undo entry

[dark roost]

https://pastebin.com/V39MuzC4
I have a custom VisualElement that I would like to be able to update after adding stuff to it using VE.Add(). Under some circumstances when loading up the Unity Editor it works immediately, but often while I know the VE has been updated in code, I don't see changes in any EditorWindow. Does anyone know what's up? See the last line (and comment).

[dreamy grotto]

i have material in a gameobject and its instance cause i reference it in the script somewhere. what i want to achieve is before i exit play mode i want to get that material props and overwrite the actual material asset. where i am mistaken

actually thats my mistake lol, i just figured it out. goMaterials[0] is my not instance material so it overwrite same properties. when i did rend.material instaned of gomaterials[0], it works now !

[dreamy grotto]

is there a way to do it via script?

[dreamy grotto]

this is happening after i did this

[unborn wagon]

Is there a way to have an asset open in a custom editor when double-clicking it? Much like when you click a .uxml file the UI Editor opens?

[delicate path]

... that would be pretty obvious, no?

[dark roost]

Yes! There is an attribute [OnOpenAsset()] in UnityEditor that can mark a default handler method for this.

[delicate path]

Yeh you can register a handler: https://docs.unity3d.com/2019.1/Documentation/ScriptReference/Callbacks.OnOpenAssetAttribute.html

[dark roost]

Example implementation:

    public static bool OpenEditor(int instanceId, int line)
    {
        Map map = EditorUtility.InstanceIDToObject(instanceId) as Map;
        if (map != null)
        {
            MapEditorWindow.Open(map);
            return true;
        }
}```

[unborn wagon]

This will however trigger for every asset that is opened right? Cause I have a ScriptableObject asset of type Item. I wonder if I can simply add a header in the class of that ScriptableObject to keep it "typesafe" and non-generic?

[delicate path]

It will indeed trigger for every asset - that's why the first order of business is to check if it is the right type and then bail if it isn't.

[dark roost]

No, this triggers for every object. If the handler doesn't handle the open case, it should return false.

[delicate path]

If you want an attribute related to the SO or a function within it, you would need to roll your own.

[dark roost]

Unity just checks in a round robin all the OnOpenAsset methods that are subscribed to it until something returns true, then it considers the matter settled and stops.

[unborn wagon]

ok I see - thanks entities of planet earth

[delicate path]

(This is all documented in the link above)

[unborn wagon]

var shader = Shader.Find("Standard");
There is this logic - however is there logic to find Material and Meshes the same way 😄 or just privileged shader stuff

[unborn wagon]

Well I am using AssetDatabase.FindAssets with a bunch of LINQ statements now :S

[daring temple]

Is it possible to add a ContextMenuItem to the Transform component in unity?

So like adding something here when i right-click on a Transform

[waxen sandal]

// Add a menu item called "Double Mass" to a Rigidbody's context menu.
[MenuItem("CONTEXT/Rigidbody/Double Mass")]

https://docs.unity3d.com/ScriptReference/MenuItem.html

[daring temple]

Ok thanks @waxen sandal, I'll give it a try

[daring temple]

Works perfectly, thank you

[vapid prism]

Is there a callback for when any GameObject is enable/disabled in my scene?

[earnest talon]

Apparently you can use Handles in [DrawGizmo()] calls. Is this going to cause unexpected behaviour(s) or is it intentional?

[waxen sandal]

Handles require unity editor so you need to ifdef

[earnest talon]

yeah I'm doing it in EditorWindows.

doing it so I can draw position gzimos and such

[waxen sandal]

Then it should be okay

[earnest talon]

all these gizmo/handles calls are done through editor windows only.

just confused by the fact you can do Handles in DrawGizmos

and thanks for the clarification too

Unity has tons of minutia and intricacies that just sometimes don't feel like they make sense

[dark roost]

    public class MapDoodadEditor : Editor
    {
        SerializedProperty spPosition;
        SerializedProperty spRotation;
        SerializedProperty spSprite;

        private void OnEnable()
        {
            spPosition = serializedObject.FindProperty("position");
            spRotation = serializedObject.FindProperty("rotation");
            spSprite = serializedObject.FindProperty("sprite");
        }

        public override void OnInspectorGUI()
        {
            serializedObject.Update();
            EditorGUILayout.PropertyField(spPosition);

            // EditorGUILayout.PropertyField(spRotation); // This line throws a NullReferenceException
            spRotation.floatValue = EditorGUILayout.FloatField(spRotation.floatValue); // This line works fine

            EditorGUILayout.PropertyField(spSprite);
            serializedObject.ApplyModifiedProperties();
        }
    }```
 I have a custom editor as seen here.  When I'm setting up OnInspectorGUI(), I can't seem to use EditorGUILayout.PropertyField() for floats.  Is this intentional?  Does PropertyField not accept primitive data by design? (Might be repost - Discord wasn't responding a moment earlier)

[waxen sandal]

Should work, probably something else going on

[dark roost]

I'm not sure how, but the exception is cleared now. I had moved on to building out the target mono and this editor class, so upon resetting things for a clean follow-up example I was unable to reproduce the issue. Thanks for your reply!

[dark roost]

https://docs.unity3d.com/ScriptReference/InitializeOnEnterPlayModeAttribute.html I think this does what you are looking for.

I am adding objects to an existing asset in my project folder, but I'm not sure how to set a name for sub-assets in the hierarchy either before adding or afterward. Does someone know the proper way to do this? I can see AssetDatabase.RenameAsset(), but I'm not sure if that can be used for a sub-asset.

[tawdry kraken]

If you have tried renaming it, the change might not display until you collapse/expand the asset again.
I'm not sure about the solution for this.

[dark roost]

You cannot modify subassets in the inspector at all, but I need to name objects in the asset database anyway.

[tawdry kraken]

From what I've read, the subasset should have a .name property

[dark roost]

Hmm, right. I was actually just looking at that. Here's a demo of how the project view handles subassets:

[tawdry kraken]

Pardon, I presumed you were working with code.
If you have a reference to the main asset, you should be able to load all the subassets, and loop through them, setting a new name.
I'm a bit too busy at the moment to divert my main focus, but if you have some experience it should be fairly straight forward.

https://docs.unity3d.com/ScriptReference/AssetDatabase.LoadAllAssetRepresentationsAtPath.html
https://answers.unity.com/questions/997764/how-to-programmatically-change-name-of-sub-assets.html (last post, different method)

[dark roost]

Aha! So this ended up being easier than I expected. My partial solution ended up being serializedObject.targetObject.name = EditorGUILayout.TextField(serializedObject.targetObject.name); on a custom inspector. The project view seems to only show the updated names after reimporting the whole main asset, but it's a start! .name was a good hint and I realized how these assets are actually just UnityEngine.Object files at their core (at least as I've been using them).

[tawdry kraken]

Good stuff!
I'm sure this has been solved numerous times already, so if you're looking to improve upon it, perhaps google a bit and see if there's anything on github.

[hard pine]

Is the incremental compiler default in 2022.2b? I can't find the compiler section in Unity preferences, and the package isn't showing up for me in package manager.

[visual stag]

There is no package, you enable it in the player settings under Other Settings>Configuration

[hard pine]

Ah I see it. Just a check box.

[astral crown]

Hi again, I would like to know: Where can I learn how to use OnGUI or how to customize them? I tried youtube videos, but all of those I tried to understand doesn't show anything about enums, List, arrays or things similar to this. Or class within class serialized. How can i learn all of this stuff?

[tawdry kraken]

Personally, I find I learn the most when I spend time making small and very specific things.
Searching online for how to do one specific thing is usually easy enough.
One useful tip is to actually create the docs script examples, even if just by copy/paste. They are great demonstrations.

[dark roost]

Thanks everyone for your help so far! I am trying to build a type of custom Transform drawer that isn't a real property drawer for a transform but instead reads position, rotation and scale from separate SerializedProperties. I have a picture showing the result of this code. What I am trying to figure out is how to design the labels to allow the user to click and drag to increase or decrease their values in the same way that the default property drawers do. The labels currently point to the correct control Ids.

https://pastebin.com/fxNWz6LE

[frank salmon]

Hello everyone! I'm curious if anyone else has experience with this, but I'm making liberal use of AssetDatabase.AddObjectToAsset to make scriptable objects neatly parent to some dependent assets (think, an ItemDatabase scriptable object with Item instances parented under it) but I'm concerned about performance impacts once I start hitting potentially hundreds of child assets. I'm mostly curious if Unity loads all sub assets by default whenever its loading/referencing the parent asset or if this is more of a purely organizational thing Unity let's us do?

[dark roost]

As I understand, it only loads the main asset unless you use LoadAllAssetsAtPath.

[frank salmon]

Thank you! That was also my understanding but I've been surprised before

[daring temple]

So i was able to save out all the information of a transform by right clicking and selecting "Copy Transform Matrix" using MenuItem and then using ContextMenuItem on my TransformMatrix Fields i can call "TestFunction" the problem I'm having now though is I need to know which variable is being used in the ContextMenuItem so that I can change it's value. Anyone have any ideas of how to do this?

Hi,
I'm currently using Visual Studio 2019 v8.10.20 and I dunno why, but my inline hints look like that

Does someone know why ?

I already tried going to tools, c# and enable inline hints

[cerulean creek]

using UnityEditor;
using UnityEngine;

[CustomEditor(typeof(DescriptionData))]
public class DescriptionDataEditor : Editor
{
    private SerializedProperty descriptionType;
    private SerializedProperty descriptionText;
    private SerializedProperty enableOverrideColor;
    private SerializedProperty overrideColor;
    private SerializedProperty image;

    private void OnEnable()
    {
        descriptionType = serializedObject.FindProperty("DescriptionType");
        descriptionText = serializedObject.FindProperty("DescriptionText");
        enableOverrideColor = serializedObject.FindProperty("EnableOverrideColor");
        overrideColor = serializedObject.FindProperty("OverrideColor");
        image = serializedObject.FindProperty("Image");
    }

    public override void OnInspectorGUI()
    {
        serializedObject.Update();

        EditorGUILayout.PropertyField(descriptionType);

        if ((DescriptionData.DescriptionType)descriptionType.enumValueIndex == DescriptionData.DescriptionType.Text)
        {
            EditorGUILayout.PropertyField(descriptionText);
            EditorGUILayout.PropertyField(enableOverrideColor);
            if (enableOverrideColor.boolValue)
            {
                EditorGUILayout.PropertyField(overrideColor);
            }
        }
        else if ((DescriptionData.DescriptionType)descriptionType.enumValueIndex == DescriptionData.DescriptionType.Image)
        {
            EditorGUILayout.PropertyField(image);
        }

        serializedObject.ApplyModifiedProperties();
    }
}

I did something like this

[spiral onyx]

How do i make it not blank?

[daring temple]

So there's no way to pass paramters into ContextMenuItem or get a reference to the variable that has the ContextMenuItem attribute on it?

[waxen sandal]

https://github.com/MrBinaryCats/PropyCopy try looking in this Repo

[unborn wagon]

I have this ScriptableObject:

    public class CraftingRecipe : ScriptableObject
    {
        public List<Item> components; // Item is ScriptableObject
        public List<CraftingResource> Resources { get; set; } // CraftingResource is NOT ScriptableObject
    }

When checking the asset in the Inspector (normal mode) the Resources property is hidden.
When checking the asset in the Inspector (debug mode) I can see it.

I'd like to also show it in the "Normal" Inspector view. Any idea how to do this?

[daring temple]

Thanks, i'll have a look

[cerulean creek]

Help anyone pleaseee 😦

[amber valley]

Change it to a field, or a property with a baking field

[daring temple]

Yeah like Khan-amil said you can just make it a regular field by removing the get and set so it looks like this:
public List<CraftingResource> Resources;

[unborn wagon]

I have this ObjectField the recipe object there is assigned automatically (by another editor) so I set the field to enabled = false to make sure nobody will play around with the value.

However I'd still like to allow double clicks to open the Recipe Editor for this asset. What's a way to make this work?

[waxen sandal]

Not really, you can either check if someone clicks on that recto manually and select the object or just don't use the return value of objectfield

[tiny rover]

Is there any extension outside that adds the ability to have Folders in the Hierarchy without childing the object?

[waxen sandal]

Nope

[tiny rover]

I feel like i slowly understand more and more why people like unreal engine more

[waxen sandal]

I don't understand why parent child relations don't work for you

If they allowed grouping randomly then the ui would be quite cursed

E.g. You could have objects with different parents grouped together and you either lose context or it becomes bloated af

[tiny rover]

This is really incompetent and also needs code changes

Childing is not Folder structure management, since you are interacting with properties and Code

[waxen sandal]

Either way, I don't think a solution in the hierarchy can be friendly from a ux perspective. It is relatively trivial to make something similar in a separate editor window though

[unborn wagon]

It's of type ObjectField is there even a way to listen to a click event for this?

nevermind I put a button behind it - it's way more intuitive than a faded out object field that is clickable (if one would try)

[stark flume]

what's the best way to save and load graphs made with graph view? I've tried saving and loading from a list of edges and nodes from a scriptableobject but that doesn't seem to work very well

[humble herald]

This channel may be overkill, but I'm not sure where else to ask... When I create a prefab with a model, it automatically gives a render of the object with textures as the icon. How do I change that, either by rotating it so it's facing out better, or to something otherwise more representative?

[humble herald]

This channel may be overkill but I m not

A SerializedProperty holds a property of a SerializedObject, not an object. What is the type of m_LoadParams?

Yeah, it wants to bind on something more fundamental, like a field or property. Try m_LoadParams = m_SerializedObject.FindProperty("theNameOfTheProperty");

Is the object is something you want to target specifically, or are you after it's fields?

I think so... if you're looking to walk across the properties, this would be the way with GetIterator. SerializedProperty is a bridge to send and receive data from a SerializedObject's properties individually - useful if you are binding an object on a class.

The context is: a property is a member of the parent serializedobject. If you aren't trying to work with member data, then SerializedProperty isn't for you.

Specifically connect to and work with remotely from the owning object, I mean. @copper surge

[unborn wagon]

The "header" of a list element seems to be mapped to the first property of the element type's properties. Is there a way to overwrite this behaviour to for instance use a custom string instead?

[waxen sandal]

If you make a propertydrawe you can put anything you want in there

But otherwise not

[dreamy grotto]

hey heres i have very simple custom inspector

which shows object field when istest true but theres a problem

when i enter play mode

bool is set to false

I have a small problem with my project. Im using GetPropertyHeight to change it, I'm currently using the array.size to figure out the height. The problem is that array.size doesn't change even if I close the List, any recommandation?

[waxen sandal]

check if property.isExpanded is true

Assuming I understand correctly 😛

If you draw an expander then you should also write to that

[astral crown]

yes this is what I needed, but now for some reason the height is changed from the last one I clicked on
In this exemple it's either all of them multiplied by 8 or by 1

[waxen sandal]

You shouldn't store data outside of the functions in a propertydrawer

The instance of the property drawer is reused across different fields

(you can disable reusing but I've had some issues with it in the past, iirc it's another override)

[astral crown]

Alright thanks, I'll change my code and see if there is still problems

[unborn wagon]

excuse me a what? Never heard of that

[astral crown]

Noice it works now!

Well I still need my Color[] couleurs = new Color[2] {Color.black, Color.white*3};

It's for changing the color based on the indexValue of one of my enum

to change it's color (mostly for fun)

[waxen sandal]

If it's static/constant data then that's fine

[astral crown]

Nice!

[astral crown]

Can I use methods? Just in case

[waxen sandal]

Yeah

[astral crown]

I'm so glad it works, thanks! I don't know if it's legit, but it's honest work lol

[astral crown]

I don't understand why there's such a big difference between calling it from another script vs attaching it:

We can see the result is very different

There's a huge space for no reason on the first script (Serializing a field of type Equipe) vs below the class itself attached

[astral crown]

This is weird...

It feels like the height are saved for some reason

[waxen sandal]

Can't know without posting code

And I'm going to bed

[astral crown]

Oh well good night then, it's alright. I don't think it's my code yet

I think I had to reset the library, for now it works again

[dark roost]

Hello! I'm struggling with a simple problem: I'm trying to figure out the simplest way to display a list in a custom editor, similar to how Unity displays them by default. I wasn't able to identify a method in GUILayout, EditorGUILayout, etc. to take a (serializable) list and display it.

[visual stag]

If you're not modifying it, just use a PropertyField.
Unless you really need to change the layout of an editor completely, PropertyDrawers can handle most things. You should really be using PropertyField for as much as possible when making custom editors.
If you do need to display a list in an IMGUI inspector then ReorderableList is the class for that; you'll probably need to google for some tutorials as it's not straight forward. UIToolkit is easier in this regard imo; though still not completely straight forward.

[astral crown]

Yeah PropertyField is indeed the answer that's how I made my Lists
Tho my knowledge is indeed very limited, so correct me if I'm wrong XD

You might have to use override GetPropertyHeight as well to change the height if you get some problem (like ur elements are on top of each others), I think so

[spiral onyx]

How do i fix that?

[shadow violet]

Im trying to persist changes made to a ScriptableObject in the Editor (it only needs to work in the Editor and not for runtime or on any Mono scripts), that ScriptableObject just holds a list of strings representing GUIDs - what im trying to do is basically have Unity remember a list of specific assets for the next time I open the project, I assumed storing those GUID's in a ScriptableObject would help me do that, but it seems GUID's themselves get reset, so I tried a string list instead, and it seems that got reset too? Do I have to call a specific "SaveSOStatePlease" API before Unity exits or something? The SO list persists between recompiles and even re-opening my custom Editor window that reads the SO, but seems to reset if I re-launch the editor

[gloomy chasm]

You can google why SO changes are not saving, there will be lots of answers as this is a very common thing. Basically, you need to either use SerializedObject or to do EditorUtility.SetDirty(SO)

[shadow violet]

Ah, EditorUtility.SetDirty(SO) is what I was looking for, thank you - I had thought that Unity automatically serializes the SO, so changes to it would also automatically get saved/detected as changed when the Editor closes, as it does with non-editor SO's (like if I made a "player stats SO" for example, made a change and re-launched the project, that change would persist, I assumed the same logic applied here), good to know though, thank you again

[gloomy chasm]

SetDirty is telling it that something changed.

[chrome jacinth]

Does anybody know why I get this error:

im new to untiy and completely lost

[abstract olive]

For some reason line 44 gets _variants properly, but the next line where it tries to get the array element at the index tells me there isn't an array, even though there is one. It says the array element type properly and how many elements there are, but the next line doesn't execute properly and crashes if I hover over it in VS to check the values. Unity then gives me an error about an overflow in the memory allocator that has to do with the boxedValue property. This is in a custom editor for Room, which is a ScriptableObject. _variants is a list of RoomVariants which is a System.Serializable class. I can't figure out what's going on here

44.  SerializedProperty variants = serializedObject.FindProperty("_variants");
45.  SerializedProperty variant = variants.GetArrayElementAtIndex(_variantIndex);
46.  SerializedProperty allTileData = variant.FindPropertyRelative("_tileData");
47. 
48.  for (int i = 0; i < allTileData.arraySize; ++i)
49.  {
50.    SerializedProperty tileData = allTileData.GetArrayElementAtIndex(i);
51.    SerializedProperty names = tileData.FindPropertyRelative("_names");
52.    SerializedProperty types = tileData.FindPropertyRelative("_types");
53.
54.    for (int j = 0; j < tileData.arraySize; ++j)
55.    {
56.      EditorGUILayout.PropertyField(types.GetArrayElementAtIndex(j), new GUIContent(names.GetArrayElementAtIndex(i).stringValue));
57.    }
58.  }

[abstract olive]

the purpose of this code is to get the variants list, then get a variant at the correct index, then get tile data from that variant and do a bunch of other stuff that isn't relevant because it's crashing before that

to be specific, like 44 works fine but inspecting it shows a few sus values like boxedValue being all messed up (but the array-related ones seem right), but line 45 is where it throws and error and crashes if you attempt to view the values in VS

some relevant code

[abstract olive]

I figured it out nvm

[dreamy grotto]

thanks a lot

this works so well

is there a way to cast serializerproperty to a type?

like i have levelcontroller class. i want to cast to this. is that possible?

LevelController levelController = (LevelController)levelPrefab; smth like this(levelPrefab is serializerproperty)

[vast isle]

I don't know why but I cant Redraw PropertyField I have To click away for changes any ideas ?``` FieldInfo[] fields = serializedObject.FindProperty("Ability").boxedValue.GetType().GetFields(BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.DeclaredOnly | BindingFlags.Public);
foreach (FieldInfo field in fields)
{

            if (field.IsPublic || field.GetCustomAttribute(typeof(SerializeField)) != null)
            {
                SerializedProperty so = serializedObject.FindProperty("Ability").FindPropertyRelative(field.Name);
                PropertyField propertyField = new PropertyField(so);
                container.Add(propertyField);
               
            }

        } ```

[gloomy chasm]

What are you doing, this looks so cursed...

You can literally use SerializedProperty to do this

[vast isle]

xD yes it cursed

Ability field is field for Abstract class I am changing the value with other ability they have deferent Fields I want to show them in the fly without the need to click away

[gloomy chasm]

First, you can just do and it will automatically add the property fields and everything for you.

SerializedProperty abilityProperty = serializedObject.FindProperty("Ability");
PropertyField propertyField = new PropertyField(abilityProperty );
container.Add(propertyField);

Or you can do

SerializedProperty abilityProperty = serializedObject.FindProperty("Ability");
foreach (SerializedProperty property in abilityProperty)
{
  PropertyField propertyField = new PropertyField(property );
  container.Add(propertyField);
}

Or you can do

SerializedProperty currentProperty = serializedObject.FindProperty("Ability");
SerializedProperty nextSiblingProperty = currentProperty.Copy();
nextSiblingProperty.Next(false);

if (currentProperty.Next(true))
{
  do
  {
    if (SerializedProperty.EqualContents(currentProperty, nextSiblingProperty))
      break;
 
    PropertyField propertyField = new PropertyField(currentProperty);
    container.Add(propertyField);
   }
   while (currentProperty.Next(false));
}

Basically, there are so many was to do it that are not cursed

[vast isle]

ahh that much cleaner ty for information

[gloomy chasm]

You're welcome haha

[vast isle]

I will just do this might fix every thing

ahh same thing still not updating after I change Ability Value not sure why

I just found a fix and its kinda weird if I do this to my root its worksroot.Bind(serializedObject);

[calm grail]

how do i make this editor script show the whole item script?

https://hastebin.com/share/imaqakader.csharp

cause i don't want to put all the variables manually

because there is a lot

i want it so that it shows the whole script in the inspector

and in the if statement i want to hide some variables

[real spindle]

You can call base.OnInspectorGUI() to draw the default inspector also

[calm grail]

alright now it shows the whole script

thanks

but how do i

in the else statements

if the enum is for example food the first one

to hide some variables

yeah how do you hide variables from the item script

[real spindle]

Set them private or [HideInInspector] so that theyre not drawn with the default inspector, then draw them in the if statements

Don't tell me your gun items have some food variables also?

[calm grail]

what do you mean

[calm grail]

they did

thats why im changing it

🤣

[calm grail]

i made it private

which means i cant access it

im gonna use the hide in inspector

[calm grail]

it works now but the variable shows all the way at the bottom

how can i make it show under the item type variable

https://hastebin.com/share/osuvacugur.csharp

[real spindle]

Reorder your code

[calm grail]

the Item code?

its good here

its under the item type

[vast isle]

what are you trying to achieve ?I might have solution

[real spindle]

If you want to draw it in a certain order, you have to draw it manually

base.OnInspectorGUI will draw everything that is normally visible

[calm grail]

how would you do this?

would you do it manually

or just keep it at the bottom

[real spindle]

I dont know, its not my game

[calm grail]

alright i'll draw them manually

how do i draw the headers though?

[real spindle]

Answer the other person whos suggesting a solution

[real spindle]

Probably just a label idk

[calm grail]

so im trying to show the whole script, instead of some of the variables, and then depending on what enum you pick, to show the specific variables which are only meant for that enum

the enum in this instance is the item type

so if i pick axe

i want to display leastDamage, maxDamage, criticalPercentage, and durability

[vast isle]

ok have you ever used interfaces ?

[calm grail]

and if the enum was lets say gun, to display ammo, leastDamage, maxDamage, and durability

[calm grail]

no i havent

[vast isle]

ok give me some times to get you simple example

[calm grail]

alright

[delicate path]

Anyone aware of a good way to test code generation in an editor test? I have an importer generate some code, but despite refreshing asset db and requesting script compilation, the script does not get compiled & loaded for the test to use when invoked via cli (by ci). The test just searches the app domain for the target type, so however Unity would slap the new assembly in, the test would find it. To be clear: When run manually everything is fine as Unity has plenty of time to spot, compile, and load the script.

[vast isle]

ok is this close to what you want?

[upbeat yarrow]

I have a piece of documentation that i remember seeing somewhere, but can't find anymore. It was a list of special editor characters like the play/pause lock/unlock text codes. Does anybody know this offhand?

[calm grail]

yes

i did it

https://hastebin.com/share/lolasegaqe.csharp

i did that

[vast isle]

ahh I see that is a way to approach it you can use switch instead of if statement

[delicate path]

Probably also want to combine that with some local booleans to avoid so much code duplication.

[burnt dove]

How can I check if the given Component is from a prefab? And if it is from one, how can I check if I'm currently editing that specific prefab (not one of its variants) in the Prefab editor and not in the Scene editor?

[gloomy chasm]

You will want this
https://docs.unity3d.com/ScriptReference/PrefabUtility.IsPartOfAnyPrefab.html

[burnt dove]

I saw that, but I'm not figuring out how to check if the component is from a prefab and I'm in the editor of the prefab that added that component.

[calm grail]

why is this lighting up in red

im trying to show the sprite variable from my script

[abstract solar]

My plan is to create an editor tool that lets me enter a mode where I can place a certain kind of object wherever I click. Would Editor or EditorTool be right for that job?

[vast isle]

yeah its seems like EditorWindow thing

[calm grail]

do you have any idea how to do this?

[calm grail]

.

show the sprite

variable

in inspector

[vast isle]

you properly typed something wrong in the screen shot it is saying m_sorce don't exist

[abstract solar]

Right, okay. How do I have it start or stop listening to events?
I have this method here:

void TrySpawnNode()
        {
            if (Event.current.type == EventType.MouseDown && Event.current.button == 0)
            {
                Ray ray = HandleUtility.GUIPointToWorldRay(Event.current.mousePosition); //Since it's from the camera, should probably be camera.current instead
                RaycastHit hit;
                if (Physics.Raycast(ray, out hit))
                {
                    GameObject node = new GameObject("Node", new System.Type[] { typeof(WorldNodePoint) });
                    node.transform.position = hit.point;
                    //TODO: Add to undo, connect nodes
                }
            }
        }

Where do I put this to have it receive mouse events?

[deft canyon]

Has anyone successfully made a SerializableHashSet in Unity? I found a few online but they all suffer from similar errors in the OnBeforeSerialization function:

System.Collections.Generic.HashSet`1[T].CopyFrom (System.Collections.Generic.HashSet`1[T] source) (at <1c318258bf0843289b0e2cbe692fee39>:0)
System.Collections.Generic.HashSet`1[T]..ctor (System.Collections.Generic.IEnumerable`1[T] collection, System.Collections.Generic.IEqualityComparer`1[T] comparer) (at <1c318258bf0843289b0e2cbe692fee39>:0)
System.Collections.Generic.HashSet`1[T]..ctor (System.Collections.Generic.IEnumerable`1[T] collection) (at <1c318258bf0843289b0e2cbe692fee39>:0)```
Stepping through, it looks like the HashSet gets corrupted somehow.  _buckets and _slots are commonly null.

[gloomy chasm]

Yeah I have, you can read a partial explanation for it here. Along with the implementation. It is MIT. https://github.com/MechWarrior99/Bewildered-Core/blob/main/Runtime/UHashSet.cs

[deft canyon]

Great, I'll take a look. Thanks!

    // we need to iterate over the items in the HashSet but for unknown

How can I make the NavMeshSurface bake if there are changes in the geometry of the prefab it contains it?
I mean, I have some prefabs with baked NavMeshSurfaces, and then I place those prefabs in the scene, inside other prefabs, or make variants of them.
If in any of those cases, the geometry inside the surface changes, the data baked in the original prefab is no longer valid... for those cases I would like to rebake. But in cases where no geometry is changed, I would prefer to use the original prefab's bake to reduce build/project size.

[lilac wave]

I am trying to make a custom window that lets me call functions from a separate script and also access various scriptable objects so I can edit the values in those objects from that editor window

I haven't really found anything that would let me incorporate more than one scriptable object per editor window

if it's possible any pointers as to where to look would be great

[tawdry kraken]

It would help to have a more solid idea of what you're trying to make.
Do you have the code for the one-ScriptableObject solution?

[lilac wave]

all I kind of found was something like this

https://forum.unity.com/threads/reference-scriptable-object-in-editor-script.255011/
https://forum.unity.com/threads/edit-a-scriptableobject-through-an-editorwindow.191355/

To ask more simply, how would I reference a specific scriptable object in an editor script to see and change it's values

like, I have a scriptable object that holds a float value, I'd want to display whatever that value is in an input field and if I edit it also apply the change to the scriptable object itself

This is basically all the scriptable object code is

[tawdry kraken]

I haven't touched SOs for a long time, but I believe you can expose those methods in the inspector, bypassing the need for an EditorWindow entirely.
ContextMenu or ContextMenuItem
I'm trying to find my example.

[lilac wave]

I mean I can directly edit the value from the scriptable object in the inspector that's not an issue

[tawdry kraken]

That was dawning on me right now. What's the need?

[lilac wave]

I'd just like to put a few of them into the same place alongside functions from a gamemanager so the most crucial values and functions are in the same place

not much need besides some convenience and wanting to gain understanding for editor scripting

I am pretty new to unity and everything

[blissful timber]

Is there an easy way to differentiate between None and Missing GameObjects?
I've found this post https://forum.unity.com/threads/how-to-check-if-a-property-is-missing-or-not-set-none.642919/ that implies that ReferenceEquals(gobj, null) should be true when gobj is None and false when it's Missing, but that doesn't seem to be true - it's false in both cases.

[tawdry kraken]

Alright. I think that approach could potentially waste a lot of time in the long run. I'm not sure if it's good practice.
However, I don't discourage exploration of quality of life. It's what I spend a lot of time on myself.
The type of practice I've heard about the most, is having one big/huge game manager with all the important stuff.

[lilac wave]

yeah that's what I am working on right now

but I use scriptable object architecture to decouple a lot of parts in my code

and the only way to edit the values of them by hand is to go and select each scriptable object separately

other than doing it by code during runtine

When I learned web dev I did a lot of time wasting possibly useless stuff in the beginning for experimentation and it was really useful for learning in the long run 😛

I just can't find any useful information online on this

I can make editor windows with sliders and buttons etc just fine, just no clue how to hook it up to functions from other scripts or scriptable objects

[tawdry kraken]

Are you aware of how to reference other scripts in general?

[lilac wave]

yeah

but trying to do something like

public FloatVariable variable;

and dragging the scriptable object in doesn't really work

maybe inspector references like that don't work and have to find reference differently

Also found solutions to having the window display information of selected objects but that doesn't really work for my usecase

[tawdry kraken]

If you're going to re-couple decoupled design, I assume you're intending to hardcode some references. I'm not sure how it could be done procedurally. So if that's not an issue, all you'd have to do is either keep a serialized reference (drag and drop) in a field, or identify them by File Path, using AssetDatabase.LoadAssetAtPath<MyScriptableObject>(path)

[lilac wave]

I don't want to recouple that's the thing

just want to reference specific scriptable objects from an editor window

oh wait

I did it

[tawdry kraken]

• in order to manage decoupled things. I'm not sure about terminology, but that was my understanding.
  You need to access objects scattered around the project.

Nice! How?

[lilac wave]

unity is giving me an error but it works

[tawdry kraken]

What's the error?

[lilac wave]

I can't read from it but I can change the value

[lilac wave]

this

[tawdry kraken]

That sounds weird. Can you share the code?

[lilac wave]

it's literally just this lol

public class GameManagerWindow : EditorWindow
{

    public float test;

    public FloatVariable variable;

    [MenuItem("Window/GameManager")]
    static void Init()
    {
        GameManagerWindow window = (GameManagerWindow)GetWindow(typeof(GameManagerWindow), false, "GameManager");
        window.Show();
    }

    private void OnGUI()
    {
        test = EditorGUILayout.Slider("slider", variable.Value, 0, 100);
        variable.SetValue(test);
    }
}

idk how to do code highlights for c#

cs

makes sense

[tawdry kraken]

better late than never :P

[lilac wave]

hm

closing and reopening the window seems to work

[tawdry kraken]

Are you certain the ScriptableObject is being changed via the EditorWindow?

[lilac wave]

yep

can't conveniently record my screen

but it seems to work

whenever I add a new object I have to relaunch the window though

[tawdry kraken]

In the code segment you shared, there is nothing connecting variable to anything

[lilac wave]

I dragged the reference in the inspector

[tawdry kraken]

Huh, I didn't know those could be used for EditorWindow. Nice

[lilac wave]

as far as I know you can see public or serialized values on any script

might be wrong though

but yeah this seems to work

do you by any chance know how to define steps for an editor window slider

[tawdry kraken]

Which Unity version are you on?

[lilac wave]

2021.3.19f

[tawdry kraken]

No idea.

[lilac wave]

all g

:D

the value even updates as I play the game and I can edit it on the fly as well

exactly what I wanted

now I have to figure out how to execute functions from button presses

[tawdry kraken]

I'm unable to reproduce this. What was the exact code?

[lilac wave]

also this

although I changed it from sider to IntField

might not work since I am using my custom FloatValue scriptable object

code to that is somewhere above too

now to bring fields and labels in the same line...

so exciting

it works

[tawdry kraken]

Solved. It wouldn't expose a normal float, but a Transform was fine.
Must be for references only.

[lilac wave]

interesting

any tips on how I can execute certain functions when pressing a button? I assume I would need references to the script which has the functions I want to call

[tawdry kraken]

For aligning: EditorGUIUtility.labelWidth

https://docs.unity3d.com/ScriptReference/GUILayout.Button.html

[lilac wave]

@tawdry kraken well thanks to you

I have figured everything out

[tawdry kraken]

Good stuff.

[lilac wave]

now I can do all of the dev tooling I want, resetting enemies, my health, score etc

[tawdry kraken]

Personal tip for when the file gets big: I use regions.
Makes it easy to move entire segments of code. Especially useful when it's all visual.

[lilac wave]

ah yeah, I saw regions in my friends code but have forgotten about them

[tawdry kraken]

Collapse the region, hold Alt + Arrow Up or Down

[lilac wave]

good reminder

and I am right to think that classes extending Editor extend what's seen in the inspector, right

[gloomy chasm]

Yes

[lilac wave]

kk

thx

[lilac wave]

you mean like so?

GUILayout.Label("Rows", GUILayout.Width(80));

or is there a way to set the width for all labels for this specific window

[tawdry kraken]

If you read the exact text to which you replied, there's the answer.

[lilac wave]

yeah just not sure where I'd put that line of code

in the options for the label like I did

or is yours just a general override for all labels in the given window

I tested it and it only reserves space

[tawdry kraken]

That's easily found by experimenting.
I place it at the top of OnGUI.
It can be changed anywhere down the line.
Just like GUI.enabled

[lilac wave]

it seems I have to pass the value to each individually

[tawdry kraken]

GUILayout.Width will override the default

[lilac wave]

yeah
