then you'll probably need to use an EditorWindow instead of an Editor script

[unkempt sparrow]

ok

like so?

[MenuItem("Window/VRtex Studios")]
        public static void ShowWindow()
        {
            varLoaderEditor window = GetWindow<varLoaderEditor>("VRtex Studios");
            window.Show();
        }

[patent pebble]

yes check the documentation for EditorWindow

[unkempt sparrow]

ok

will do

[patent pebble]

but the data won't get serialized (saved) like it does with an Editor script
if you close and open the EditorWindow the data will reset to the default values

that's probably fine for some situations, it depends on what you're doing exactly

[unkempt sparrow]

ahhh i see yeah it will be open the entire time of use unless someone accidentally closes it

there is a save mid way though aswell but this was really annoying me haha

thank you very much

[unkempt sparrow]

why do all my sliders slide together?

[patent pebble]

probably because they are all using the same field

[tardy pecan]

Hey does anyone know why some scriptable objects are changing InstanceID? Like I'm trying to save UIElement.ObjectFields referencing a scriptable object as Json, but when I reload the project after a restart or something, their instance IDs have changed and loading them via the old value in the JSON leads to wrong objects being loaded

[waxen sandal]

InstanceIds aren't persistent and are reliant on what order assets are loaded in

You can use GUIDs instead perhaps

[tardy pecan]

yeah so I guess my system can't work this way, I took another approach and I now save my stuff in nested scriptable objects (that have correct references)

thanks for the help tho

[unkempt sparrow]

i had the script working just fine and turned on my pc today and now am getting this error

using System;
using UnityEngine;

namespace VRtexStudios
{
    public class VarLoader : MonoBehaviour
    {
        public GameObject avatar;
        public int BlendShapes()
        {
            SkinnedMeshRenderer mesh = avatar.GetComponent<SkinnedMeshRenderer>();
            Mesh currentMesh = mesh.sharedMesh;
            return currentMesh.blendShapeCount;
        }
        public Array getBlendShapeNames ()
        {
            SkinnedMeshRenderer mesh = avatar.GetComponent<SkinnedMeshRenderer>();
            Mesh m = mesh.sharedMesh;
            String[] arr = new string[]{};
            for (int i= 0; i < m.blendShapeCount; i++)
            {
                arr[i] = m.GetBlendShapeName(i);
            }
            return arr;
        }
    }
}

thats the current main script and i have no clue why its not assigning avatar. any ideas?

[waxen sandal]

#💻┃code-beginner

[unkempt sparrow]

ok

[unkempt sparrow]

i make a slider for each blendshape and need them on seprate fields how do i do that?

i have them as all separately generated names but none move independently

for(int i = 1; i < totalShapes; i++)
            {
                scale = EditorGUILayout.Slider(Blendshapenames[i],scale, 0, 1);
            }

that is how i generate them

what is moves like

[gloomy chasm]

That is because they are all setting the variable scale's value

[unkempt sparrow]

so make a array of floats and assign it to them?

[gloomy chasm]

It depends on what you want

[unkempt sparrow]

each of them need to be customizable and i need to be able to save a current state of them all

[gloomy chasm]

Since you have a collection of blend shape names, I assume you are wanting to set the value of the blend shapes

[unkempt sparrow]

yes

[gloomy chasm]

So set the value of the blend shape then... no? If you want to just store the values, then yeah you will need a array/list of floats

[unkempt sparrow]

ok awesome thank you 🙂

@gloomy chasm you still here?

[gloomy chasm]

my man...

[unkempt sparrow]

sorry for the @

[gloomy chasm]

If ya have a question, ask and someone will answer. If it is about a previous conversation you can either at me or reply to my previous message. But please include the question in the message

[unkempt sparrow]

i have set up the array and i get no errors whether it be syntax or in unity but i am now unable to slide any of the sliders.

yeah thats why i @ you cause its about the same problem

my bad for not having the question in there

sorry

[gloomy chasm]

All good, now you know for the future 🙂

[unkempt sparrow]

thank you 🙂

[gloomy chasm]

Are you defining the array in the class or the method?

[unkempt sparrow]

class definition method assignment

            window.Show();
        }

        public override void OnInspectorGUI()
        {
            varLoader mainWindow = (varLoader)target;
            if (GUILayout.Button("Collect Blendshapes"))
            {
                totalShapes = mainWindow.BlendShapes();
                blendShapeNames = mainWindow.getBlendShapeNames();
            }
            EditorGUILayout.IntField("Blendshapes", totalShapes); 
            blendShapeVal = new float[totalShapes]; //asignment
            for(int i = 1; i < totalShapes; i++)
            {
                blendShapeVal[i] = EditorGUILayout.Slider(blendShapeNames[i],scale, 0, 1);
            }
        }
    }
}

[gloomy chasm]

You are reassigning it each update, that has the same effect as if you defined it in the method

[unkempt sparrow]

ooo

that makes sense

[gloomy chasm]

Also note that since you are defining it in the Editor class, the values will not be saved to the component so when you select a different GameObject the values will be lost

[unkempt sparrow]

hmmmm

so if i define it in the script then use it in the editor would i be able to save the values?

[gloomy chasm]

Yes

[unkempt sparrow]

thank you 🙂

[unkempt sparrow]

so i have refactored it and all variables so there is no reassigning every update. However it still isnt working

namespace VRtexStudios
{
    [CustomEditor(typeof(varLoader))]
    public class varLoaderEditor : Editor
    
    {
        private static float scale;

 public override void OnInspectorGUI()
        {
            varLoader mainWindow = (varLoader)target;
            if (GUILayout.Button("Collect Blendshapes"))
            {
                mainWindow.Load();
            }
            EditorGUILayout.IntField("Blendshapes", mainWindow.totalShapes);
            for(int i = 1; i < mainWindow.totalShapes; i++)
            {
                mainWindow.blendShapeVal[i] = EditorGUILayout.Slider(mainWindow.blendShapeNames[i],scale, 0, 1);
            }
        }
    }
}

[patent pebble]

@unkempt sparrow you are reading the scale value on every the loop

of course it's never gonna change

your scale value is never changing because you are never assigning anything to it

but why are you still using a single float value to represent EVERY value of an array?

change scale for blendShapeVal[i]

[unkempt sparrow]

interesting i mis understood the documentation

i thought where i had scale was the type of value used on the slider not the value itself

works fine now 🙂

[patent pebble]

this is the example in the Slider method documentation

scale = EditorGUILayout.Slider(scale, 1, 100);

you need to pay more attention to the docus examples

[unkempt sparrow]

yeah i looked at that specifically

i guess i do it also was 330 am when i was doing it haha

so makes sense

i need to sleep more running on like 3 hours today...... buuut first prototype it done!

[idle tree]

Im running this code to build a library of all the rooms in my game.
I was able to build and run this no problem before, but now im getting errors that AssetDatabase is only do-able in editor.

I dont know why it was building and working before or what changed to make it not, but how do I remove editor namespace dependancy on this code?

How do I build a dictionary of all the rooms in my project if I am not allowed to reference the project?

[unkempt sparrow]

whats the stack trace?

[idle tree]

I am not experienced enough to know what a stack trace is, how can I get you that info?

[unkempt sparrow]

are you running it in unity?

[idle tree]

Yes

Do you mean the errors in console?

[unkempt sparrow]

yes click on one

[unkempt sparrow]

and then copy paste the code underneath

[idle tree]

The build fails because I am trying to reference UnityEditor namespace in a build

which you can't do

but I don't know how to build my dictionary without it

[unkempt sparrow]

why do you need unityeditor namespeace?

[idle tree]

#↕️┃editor-extensions message
see the highlighted references to AssetDatabase, those

I need a way to do that same functionality, without using AssetDatabase

[unkempt sparrow]

lemme look at something real quick

[idle tree]

Okay

the dictionary is <string, GameObject> for reference

[unkempt sparrow]

thank you

[idle tree]

You can't serialize a Dictionary so I can't save it, I have to build it at runtime (to the best of my knowledge)

[unkempt sparrow]

do you have to use assetdatabase?

[unkempt sparrow]

or could you make your own dictonary and populate it with the information you need?

nvm

assetdata base is thing you should use for this. i think

aight yeah if you make the script in the "Editor" folder and then use assetdatabase you should be fine just have it edit the script it should relate to.

this script must be in a folder called "Editor"

[idle tree]

You arent understanding

I need this dictionary at runtime, in my game, for my game to work

Dictionaries cannot be serialized

its fine though I thought about it, I can separate the code to build the list and the dictionary and pre-build only the list during Build I think

[unkempt sparrow]

you can declare the dictionary in the main script and then use them in the editor which will allow you to save them and have them at runtime

[patent pebble]

@idle tree for a simple approach most people just store two lists in a ScriptableObject and then at runtime they make a dictionary from the lists

you could also just implement your own serializable dictionary

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

[unkempt sparrow]

was i close?

[patent pebble]

nope, bunp's problem was because they are trying to read data from an asset at runtime in the build

they need to predefine the data somewhere (ie: in s ScriptableObject in the Resources folder) to be able to load it at runtime

this whole conversation should have been in other channels like #archived-code-general
this channel is for editor extensions and such

[unkempt sparrow]

ok would they be able to do that if they defined it in there script first and then used a editor to allow for the assetdatabase?

check me on this but is this channel for questions regarding custom editors and extensions?

[patent pebble]

yes, any topic related to making editor tools and extending Unity's functionality

[unkempt sparrow]

ok cool just making sure

[patent pebble]

when in doubt, check #🔎┃find-a-channel for a list of all the channels

it's important to keep questions and conversations on the topic of the channel

[unkempt sparrow]

will do

yeah i feel like i have done a alright job with that so far or would you say i need to improve a significant amount?

[patent pebble]

yes, you need to make sure to share appropriate context when asking for help. Like when asking about a console error, if you don't provide any code people can't try to help you
put the effort in your questions so other people can help you better 🙂

[unkempt sparrow]

very true

ill do better this is a very big project and i have a decent amount left to do so i will for sure be asking many more questions and hopefully answering questions better aswell.

[patent pebble]

and it's ok to ask in #💻┃code-beginner and #archived-code-general if you are having problems with basic code stuff, even if they are in an Editor script 👍

[unkempt sparrow]

yup i have many times 🙂

thank you 🙂

[remote yarrow]

Dictionaries have been serializable for at least 5 years, but you have to use a special callback to do it EDIT: as MedLed linked to - but most of us have by now made this into re-usable code so we don't have to think about it any more) (and there's a wider automated solution Coming Real Soon (tm))

[tepid shell]

Hey there, maybe someone can point me in the right direction.

I have custom timeline track and clips that allow me to loop within a defined section of a timeline while a script is running. I've made it so it's possible to set the start time of the loop with an offset relative to the clip's start time (checkout the screenshot), and everything works quite well.
However at the present time there is no visual information that indicate when the loop will start on the timeline itself, the only information you have is the time offset, in seconds, that you can change manually in the clip's inspector.
Is it possible to add an icon, like an open square bracket for instance, on top of the custom clip's rectangle, in order to indicate when the loop begins? I know I can change the looks of the inspector, but I don't know if I can mess around with the looks of the timeline.

[tough stream]

Hi!
I'm searching for some kind of addon to make my nodal custom window. In the past, i tried making my own nodes, but... It didn't really work out 💀
I'd like to know if you guys know any extensions or package that allow me to create new nodes easily, i've got "XNodes" but idrk what it's worth

[waxen sandal]

[tepid shell]

Never mind that, I just learned of the existence of ClipEditor which should be able to do what I'm looking for.

[patent pebble]

this might be kind of a dumb question, but do I need to call SerializedObject.ApplyModifiedProperties if I'm using an EditorGUI.PropertyScope?

iirc there's no need for it, but asking just in case

can't find a concrete answer online

[waxen sandal]

Yeah you do

But most often you do it in a property drawer which handles it for you iirc

[waxen sandal]

(looking at the source)

[gloomy chasm]

You you do, all it is is

EditorGUI.BeingProperyty(..);
// your code...
EditorGUI.EndProperty();

(I mean that literally all it is)

[patent pebble]

ah right, that may be it

i'm making a sort of generic property drawer base class and neither it nor the derived classes call ApplyModifiedProperties

so I was kind of freaking out about the values retaining the data correctly

yeah just tested on an EditorWindow, you do indeed need to apply the modifications

[gloomy chasm]

That is how the PropertyDrawer works, you handle applying in whatever draws the properties in the end

[patent pebble]

Yeah it makes more sense now. I had only scratched the surface on PropertyDrawers/PropertyAttributes with the basic stuff

i'm trying to make more complete implementations now so I was going over everything to see how it worked

for example I was trying to do SerializedObject.Update() in my drawer which reset the values of all the previous fields to the default value

😅 silly me

[pure siren]

Is it possible to mark a serialized object properties as modified?

[shadow violet]

Just curios, is there a way to access the "Select Object" window that pops up when your assigning object fields by the inspector? Im wondering if its possible to make it show up on a button press or something that isnt specifically a ObjectField

[gloomy chasm]

Sure is. iirc it is something like EditorGUIUtly.ShowObjectPicker(..)

[gloomy chasm]

What do you mean?

[shadow violet]

Oh aawesome, thanks Mech

[pure siren]

I'm calling a method with an InspectorGUI button on a MonoBehaviour script. That method reads in some values from a file on and modifies some of the properties. The scene is not showing as modified even though the properties are updated.

And if I reload the scene the changes are gone

[gloomy chasm]

You should use SerializedProperty and SerializedObject to modify properties in the editor (more info in pinned messages in this channel)

[pure siren]

I'm not modifying the properties with SerializedProperty, because I wanted the method to work at runtime and in Editor, but I'm guessing that's not possible

[gloomy chasm]

What you would do is basically recreate the method in the editor script using SerializedProperty. That is the 'right' (and heavily recommended) way to do it. The other option is to use EditorUtility.SetDirty(obj).

However that will not support Undo or prefab overrides

[pure siren]

Thanks I figured that was the case. Thanks for the info!

[patent pebble]

hmmmm i'm struggling a little bit with PropertyDrawer heights

i'm getting different results depending on if the Inspector is docked or not

is there a way of getting the EditorWindow in which the current PropertyDrawer is being drawn?

i need to know in what window its being drawn to add an extra pixel to get the correct value

it's literally just a +1 when the Inspector window is floating not docked to anything

it's so annoying... UNITY WHY YOU DO THIS TO ME... 😓

[gloomy chasm]

Can you show?

[patent pebble]

sorry not at my computer right now, i can share all the code tomorrow and provide better gifs 😅
Basically i have a property drawer that draws a custom HelpBox that wraps the text.
At some point there's a discrepancy of 1 pixel between the actual WIDTH of the HelpBox and thw width of the inspector,
which makes the box wrap the text but the height gotten from the property drawer doesnt match
The weird bug is that it only happens when the inspector is docked, when it's floating the width and height match perfectly

https://media.discordapp.net/attachments/533353544846147585/936931971895001088/GIF.gif

I had shared that gif before

I dont know if this is caused by me using a custom GUIStyle with non standard padding values ( i've experienced situations where having odd padding values instead of even values would cause situations like this)
Or maybe it's a floating point inaccuracy issue

Or some other obscure internal bug with Unity

In that gif there was actual height errors caused by me setting incorrect values. But now i fixed everything, and it works correctly, except for that rogue pixel 😅

[elfin robin]

yo

does anyone know why when i parent an object to a bone it changes the anchor point of the bone?

[patent pebble]

@gloomy chasm here's the gif with the problem

as you can see, as soon as I undock the window, there's no issue

[visual stag]

welcome to the world of IMGUI

[patent pebble]

🙃

[visual stag]

where pain is pain and pain pain pain

[gloomy chasm]

Odd...

Just an idea, and could be wrong, but you could try rounding the x and width after getting them and before using them just incase something is happening there

[patent pebble]

done that already 😅

i was printing non-rounded float values, but rounding them didn't fix it

[gloomy chasm]

Can you share the code that calculates the property height?

[patent pebble]

yep, one sec

private static float Spacing => EditorGUIUtility.standardVerticalSpacing;
private static float InspectorWidth => EditorGUIUtility.currentViewWidth - EditorStyles.inspectorDefaultMargins.padding.horizontal;
//private static float InspectorWidth =>  EditorGUIUtility.currentViewWidth - EditorStyles.inspectorDefaultMargins.padding.horizontal - 1;

public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
{
    if (ValidTargetType == false)
    {
        Vector2 errorBoxSize = GetErrorBoxSize(_errorContent);
        return Mathf.Round(errorBoxSize.y) + Spacing;
    }
    return base.GetPropertyHeight(property, label);
}

public static Vector2 GetErrorBoxSize(GUIContent errorContent)
{
    float width = InspectorWidth - EditorGUIUtility.labelWidth - Spacing;
    float height = ErrorBoxStyle.CalcHeight(errorContent, width);
    return new Vector2(width, height);
}

private static void SetUpStyle()
{
    ErrorBoxStyle = new GUIStyle(EditorStyles.helpBox);
    ErrorBoxStyle.fontSize = 12;
    ErrorBoxStyle.padding = new RectOffset(24, 5, 1, 2);
}

here's all the relevant code

i'm also suspicious of EditorGUIUtility.currentViewWidth

When docked

• The point where the wrapping happens visually is at a EditorGUIUtility.currentViewWidth of 339
• The point where the wrapping actually triggers the correct value is at 337
  When not docked
  -Both happen at 337 in sync

[gloomy chasm]

Okay

So it is probably a less than ideal solution

but you could get the rect in OnGUI and use its width instead

[patent pebble]

@gloomy chasm that might work. I wanted to avoid having to workarounds like that

but seems undocking the window doesn't affect the position Rect

while it offsets the EditorGUIUtility.currentViewWidth by 2 pixels

i guess Unity just adds 1 extra pixel on each side of the EditorWindow when it's undocked for some god damn reason

[gloomy chasm]

Its the outline of the window

[patent pebble]

yah, that's my guess

i wonder who thought it was a good idea to do that 😅

[gloomy chasm]

Oooh

what are you doing in OnGUI

that is where the trouble would be (partly)

[patent pebble]

hmmm i do this

public static Rect DrawGenericError(Rect position, GUIContent labelContent, GUIContent errorContent, bool disableLabel = false)
{
    // Calculate rects
    Rect labelRect = CalculateErrorLabelRect(position);
    Rect errorBoxRect = CalculateErrorBoxRect(position, errorContent);
    Rect errorIconRect = CalculateErrorIconRect(position);

    // Draw label
    using (new EditorGUI.DisabledScope(disableLabel))
    {
        EditorGUI.LabelField(labelRect, labelContent);
    }

    // Draw error help box
    if (Event.current.type == EventType.Repaint)
    {
        ErrorBoxStyle.Draw(errorBoxRect, errorContent, false, false, false, false);
    }

    // Draw error icon
    GUI.DrawTexture(errorIconRect, PropertyDrawerGlobalCache.ErrorIcon);

    return errorBoxRect;
}

private static Rect CalculateErrorLabelRect(Rect position)
{
    Rect result = new Rect(position);
    result.x = position.x;
    result.width = EditorGUIUtility.labelWidth;
    result.height = EditorGUIUtility.singleLineHeight;
    return result;
}

private static Rect CalculateErrorBoxRect(Rect position, GUIContent errorContent)
{
    Rect result = new Rect(position);
    result.x = position.x + EditorGUIUtility.labelWidth + Spacing;
    result.width = position.width - result.x + EditorStyles.inspectorDefaultMargins.padding.left;
    result.height = PropertyDrawerErrors.ErrorBoxStyle.CalcHeight(errorContent, result.width);
    return result;
}

private static Rect CalculateErrorIconRect(Rect position)
{
    Rect result = new Rect(position);
    result.x = position.x + EditorGUIUtility.labelWidth + Spacing + PropertyDrawerErrors.ErrorIconLeftPadding;
    result.y += 2;
    result.width = PropertyDrawerErrors.ErrorIconSize;
    result.height = PropertyDrawerErrors.ErrorIconSize;
    return result;
}

so in the CalculateErrorBoxRect()
i get the width like:

result.width = position.width - result.x + EditorStyles.inspectorDefaultMargins.padding.left;

and in the method that gets the height for GetPropertyHeight() i do

float width = EditorGUIUtility.currentViewWidth - EditorStyles.inspectorDefaultMargins.padding.horizontal- EditorGUIUtility.labelWidth - Spacing;

i guess that's causing the discrepancy

[gloomy chasm]

Yeah you don't have the same logic in them

that would be doing it

[patent pebble]

yeah, i mean... one would guess using EditorGUIUtility.currentViewWidth for an editor window
would give a consistent, reliable value that I can use for all of my IMGUI needs!

HOW NAIVE OF ME 🙃

[gloomy chasm]

Well you shouldn't really be using that anyway

Because if the property is drawn in an editor window it could be very in consistent for what you actually want

[patent pebble]

hmmm yeah

what approach do you recommend for this sort of thing
just caching the Rect position from the OnGUI method and using it for the GetPropertyHeight method?

[gloomy chasm]

I think so

[patent pebble]

it seemed like a non-ideal approach since the drawer gets first the height and then draws the OnGUI

but eh, i guess it'll do

[gloomy chasm]

Yeah, it isn't ideal

My only concern really is that I don't remember how EditorGUI.GetPropertyHeight(..) works

Because if that calls the GetPropertyHeight method of the property drawer...

[patent pebble]

yes it does iirc

there's an internal method to get the height

i've used it a couple times

https://github.com/Unity-Technologies/UnityCsReference/blob/master/Editor/Mono/ScriptAttributeGUI/PropertyHandler.cs#L293 this one

i used it for a PropertyDrawer where I needed to have some custom logic on GetPropertyHeight but then I actually needed to get the "raw" height in the OnGUI method

object nullHandler = ScriptAttributeUtilityAccessor.SharedNullHandler;
PropertyHandlerAccessor accessor = new PropertyHandlerAccessor(nullHandler);
propertyHeight = accessor.GetHeight(property, GUIContent.none, true);

by using an "empty" PropertyHandler

[gloomy chasm]

Really what it comes down to is that the property drawer system wasn't made for this sort of thing

[patent pebble]

yeah i've seen a couple of implementation for this sort of complex PropertyDrawers and they just end up overriding the entire Editor so they can handle things more comfortable

NaughtyAttributes does that iirc

[gloomy chasm]

Yeah

it is the only choice for things like the Button attribute

I once helped a guy with some NaughtyAttribute stuff and that is when I learned that it was extremely inefficient

[patent pebble]

what's inefficient? overriding the Editor or doing it the "normal" way?

[gloomy chasm]

I just mean NaughtyAttribute's code. For example it gets every class that inherits from x every single OnInspectorGUI instead of caching it

[patent pebble]

oh yeah

Naughtyattributes also likes to break your inspector under certain conditions

[gloomy chasm]

I think that case may be that they simply don't understand how IEnumerable works though (in the case of the reflection example)

[patent pebble]

yeh maybe

one time NaughtyAttributes locked my entire project because I had deleted a script and there was still fields of that type
so their Editor override was freaking out and not rendering anything

[gloomy chasm]

But overall I found the code kind of messy

[patent pebble]

there's also StackableDecorators, i digged around through their code and I think they do all of their stuff in actual PropertyDrawers and not overriding the Editor
and they do anything NaughtyAttributes can do

[onyx harness]

When you round a value, make sure you round position & size (not just the size)

[patent pebble]

ah, thanks for the reminder lol

[gloomy chasm]

That can't be true if they have the Button attribute afaik

[patent pebble]

i can't remember exactly, it's been a while since i've look at their code

well I was about to try implementing a PropertyAttribute for adding a button to a method

so I guess I'll find out the hard way lmao

[gloomy chasm]

Might be difficult

[patent pebble]

lol RIP

[gloomy chasm]

Actually, I wonder if you can inherit from it and use AttributeTargets.Method

[patent pebble]

only one way to find out

BRB

[gloomy chasm]

👍

[patent pebble]

nah it doesn't call the OnGUI method

[onyx harness]

You can always add the name of the method as an argument of the Decorator

But you will end up with static only

[patent pebble]

@onyx harness yeah but if you use a PropertyAttribute in a method the drawer doesn't call any of the methods

it just becomes useless

i wonder if there's some internal callback to hook up to Editor GUI updates

similar to EditorApplication.projectWindowItemOnGUI

[onyx harness]

You can't put a PropertyAttribute on a method O_o

[patent pebble]

i mean, unity lets you do it

it just doesn't do anything with it

[minor knoll]

Does anyone have an idea on how to automatically uncollapse the hierarchy when starting the game? I hate it that Unity automatically collapses the hierarchy upon entering play mode.

[patent pebble]

it doesn't happen for me

are you sure you don't have some tool or something that collapses your hierarchy

test if an empty project does the same thing

[minor knoll]

It's a multiplayer game with an extra scene for loading all the background stuff and I think once there is a dontdestroyonload in it, it automatically collapses everything

Hello. I have 2 monitors. In monitor 1 I keep my visual studio in other the Unity editor. I would like that any time I press save in Visual Studio the editor compiles the changed scripts. Unfortunately its only happening when I move my cursor over the editor and focus it. This is very ineffective and I wonder if it can be tuned as I describe?

[barren moat]

There is a discussion here. https://www.reddit.com/r/Unity3D/comments/e9qwe3/recompile_in_background_when_saving_script_in/

I believe it would be possible to write a an editor script that does this, but you'd probably need to set up a file watcher and force a reimport when any file changes.

There may be an option for this I'm not aware of.

[remote yarrow]

Not only is that method broken (has been broken for YEARS) but the latest bug I submitted (few monhts ago IIRC) on it got closed as 'FIXED', and when I asked for more info was told: 'we're changing the documentation in future releases to state that it doesn't work'. LMAO. TL;DR: Unity's trying to kill that API call, don't even try to use it.

[dull rune]

I restarted Unity (did not change anything) and now it works as I want.

Like it read my mind orsmth

[waxen sandal]

Use Rider instead, if it still doesn't work

[dull rune]

What is Rider?

Hi, is it possible to change docked editorwindow width from the script?

[gloomy chasm]

Do you mean undock/dock a window?

[warm valve]

actually I want to change it without undocking.. Right now if I set EditorWindow position it automatically undocks. I want to prevent it.

I need to set the exact width of the docked window, just as I do it in UI

[gloomy chasm]

Ah, you will need to use quite a bit of reflection to do that

[warm valve]

trying to hack that right now.. thought maybe somebody already done it 🙂

[gloomy chasm]

Why are you trying to set the width in the first place?

[warm valve]

well, I need to render my scene view pixel perfect: so that all texels would be perfect squares. I thought maybe snapping the editor window size would be the easiest way to do it 😄

its not a problem for gameview, I can easily control that with camera rect (by adding small line so that all pixels are squares). But in scene view I cant change the camera rect.

well, I can, but it gets overwritten somewhere I think.. has no effect unfortunatly

[dull rune]

How is it better?

Hmm, not free.. cancel

[obsidian skiff]

To be fair, it is a jetbrains* product

[teal timber]

is the preview window some kind of scene or "place" i can put arbitrary things for previewing assets, or like if i want a 3d thing there do i need to actually just render it using a camera onto a rendertexture or whatever

an example close to what i'd actually like to do is create a preview for a scriptableobject asset which would display a UI element based on the strings and textures contained/referenced in the scriptableobject

[waxen gate]

is plasticscm down because it takes 2 minutes for me to preview my game and it gives the error message "the host closed the socket"

i just straight up cant playtest my game because every frame its trying to run this

[iron wadi]

Hi guys. I took this screenshot from a 3rd party asset and I wonder how I can implement my own buttons like this.

I am experienced on developing editor extensions but I have no idea about how to do this.

Any idea how to start?

[gloomy chasm]

It depends, the top right buttons might be able to be done with reflection, otherwise you need to use Harmony. The button on the left could be done with UIToolkit, otherwise again the answer is Harmony. What is the asset?

[onyx harness]

void ShowButton(Rect r)

[patent pebble]

for a regular EditorWindow that you make, you can do this to add buttons to the top bar and generic menus to the three dots menu

public class EditorWindowTopBarButtons : EditorWindow, IHasCustomMenu
{
    private GUIStyle _lockButtonStyle => "IN LockButton";
    private bool _locked = false;

    [MenuItem("Test/Top Bar Buttons")]
    public static void MakeWindow()
    {
        EditorWindow.GetWindow<EditorWindowTopBarButtons>();
    }

    // Add generic menus to the three dots button
    void IHasCustomMenu.AddItemsToMenu(GenericMenu menu)
    {
        menu.AddItem(new GUIContent("Lock"), _locked, FlipLock);
        menu.AddItem(new GUIContent("Button"), false, DoButton);
    }

    // Magic method which Unity detects automatically.
    private void ShowButton(Rect position)
    {
        // Drawing a toggle
        _locked = GUI.Toggle(position, _locked, GUIContent.none, _lockButtonStyle);

        // Drawing a button
        position.x -= position.width;
        if (GUI.Button(position, ""))
        {
            DoButton();
        }
    }

    private void FlipLock()
    {
        _locked = !_locked;
    }

    private void DoButton()
    {
        Debug.Log("Button pressed");
    }
}

but the screenshot you shared is probably doing something different

[onyx harness]

It probably uses exactly ShowButton

[patent pebble]

but i don't think they are making their own project view from scratch, they are probably just injecting the buttons in some other way

or can you use ShowButton to add to the Unity default windows?

[onyx harness]

ShowButton is not clipped

that's the trick

[patent pebble]

what do you mean by that?

[onyx harness]

You can overdraw out of the given Rect

[patent pebble]

ah lol

[onyx harness]

Try it with a Button or a DrawRect

[patent pebble]

so you think they're creating a mock editorwindow and using the ShowButton from there?

to add it to the Project browser window?

[onyx harness]

Oh you are right, I forgot it was in Project window

Well probably injected I would say

[patent pebble]

yeh that was my guess

maybe you could just gett the total Rect of the Project browser window and draw the buttons on the top right

but i guess they are doing something else since they also inject the star button for the favorites thing on the top left

[onyx harness]

Oh I thought the star was from recent Unity

[patent pebble]

no idea, looks like a custom thing

but i don't know

[gloomy chasm]

So basically.. what I said to start with 😛

[iron wadi]

The asset seen in my screenshot is this one:
https://assetstore.unity.com/packages/tools/utilities/favorite-assets-198746

Thanks guys for detailed info. I checked what Harmony is. It looks like an interesting library but I won't go to that length (like injecting code to Unity editor) just to be able to add a button to project window. I'll see what I can do with UIToolkit.

@gloomy chasm I developed IMGUI extensions for Unity but I haven't experienced UIToolkit yet. Even if I implement my own window with UIToolkit, how am I supped to inject a button into an existing window? Like querying for the project window in a DOM like object structure?

[gloomy chasm]

var windows = Resources.FindAllOfType(projectBrowserType);
foreach(var win in windows)
{
var newButton = new Button(() => Debug.Log("Custom Button") {text = "New Button" };
  win.rootVisualElement.Add(newButton);
}

[iron wadi]

Thank you. I'll check that.

Also, I have this checkbox implemented before with the help of a library called UnityToolbarExtender.
https://github.com/marijnz/unity-toolbar-extender

Now I checked the source code of this library and saw that it's doing its job with reflection and by looking for a VisualElement in a Root object. This root object is in a scriptable object called "UnityEditor.Toolbar" and loaded by Resources.FindObjectsOfTypeAll method. Interesting stuff...

That's the same way you showed in your example. Thank you!

One last question. How would I know the value of projectBrowserType ?

[onyx harness]

By cleverly searching it

[iron wadi]

Ok

Thank you guys

[onyx harness]

Project is trickier than the rest

as its type name is not following the "normal convention"

UnityEditor.ProjectBrowser is what you want

[iron wadi]

Awesome. Thank you!

[onyx harness]

"ProjectBrowser" does not follow the common "Window" suffix

[waxen sandal]

Anyone knows where the gradle external tool settings are located in the source? I find references to IPreferenceWindowExtension and HasExternalApplications but no gradle implementation of that exists

Or what the editorpref is called that lets you use a non bundled gradle?

[waxen sandal]

Foudn it btw, GradleUseEmbedded

[gloomy chasm]

Anyone know how you get an object field to show the "Missing (..)" text?

[patent pebble]

i think there was an internal ObjectContent method that accepted an instance ID as a parameter

and if you passed a non-valid InstanceID it would show that

but can't remember

[gloomy chasm]

Turns out you can't. The only option is to just draw the style, oh well I guess that works

[patent pebble]

you can also pass a destroyed object of the type you want to get the missing text

private void OnEnable()
{
    _go = new GameObject();
    DestroyImmediate(_go);
}

private void OnGUI()
{
    string missingString2 = EditorGUIUtility.ObjectContent(_go, typeof(GameObject)).text;
    EditorGUILayout.LabelField($"missingString2: {missingString2}");
}

what's the name of the style to get the "Missing" thing? I'm curious

[gloomy chasm]

That seems so much dirty and less performant haha

[patent pebble]

haha yes indeed 🙃

[gloomy chasm]

This is what the Material variant parent field does in 2022

[patent pebble]

ah they just manually do it

[patent pebble]

@gloomy chasm ah digging around on my reflection examples found this one

public class EditorGUIUtilityAccessor
{
    private static MethodInfo MI_ObjectContent = typeof(EditorGUIUtility).Method("ObjectContent", new Type[] { typeof(Object), typeof(Type), typeof(int) });

    public static GUIContent ObjectContent(Object obj, Type type, int instanceID)
    {
        return (GUIContent)MI_ObjectContent.Invoke(null, new object[] { obj, type, instanceID });
    }
}

GUIContent missingString = EditorGUIUtilityAccessor.ObjectContent(null, typeof(Material), -1);
EditorGUILayout.LabelField(missingString);

GUIContent noneString = EditorGUIUtilityAccessor.ObjectContent(null, typeof(Material), 0);
EditorGUILayout.LabelField(noneString);

if you pass an instance ID of -1 it gives you the "Missing" content
and 0 for "None" content

[onyx harness]

Maybe you can create a fake missing Object

by assigning its InstanceID to -1

[patent pebble]

@onyx harness is there a way to change the instance ID of an object?

[onyx harness]

Reflection

Or serialization

[patent pebble]

ah, right

[onyx harness]

Dont do that on existing object though

probably not good idea

But if you want to fetch any object, you can create an empty Object, reassign its InstanceID and serialize it, you will have all its content fetched naturally

[gloomy chasm]

I mean, that all could work, but also just drawing the style seems like a much more stable and performant solution

[onyx harness]

I would prefer drawing the style too

But if you prefer to stay consistent in using an Object, creating a fake object does not cost anything

[patent pebble]

ah, note for the reflection approach
using the internal EditorGUIUtility.ObjectContent() causes problems because it caches the content in this field

private static readonly GUIContent s_ObjectContent;

so if you do this

• Call ObjectContent to get a "Missing" content
• Call ObjectContent to get a "None" content
  -Draw with EditorStyles.objectField.Draw using the missing content
  -Draw with EditorStyles.objectField.Draw using the none content

both of your draws will get the "None" appearance

you can instead just use this other internal method to get the "Missing" GUIContent

private static extern string GetTypeNameWithInfo(string typeName, int instanceID);

it's what they use internally

internal static GUIContent ObjectContent(UnityObject obj, Type type, int instanceID)
{
    if (obj)
    {
        s_ObjectContent.text = GetObjectNameWithInfo(obj);
        s_ObjectContent.image = AssetPreview.GetMiniThumbnail(obj);
    }
    else if (type != null)
    {
        s_ObjectContent.text = GetTypeNameWithInfo(type.Name, instanceID); <-------
        s_ObjectContent.image = AssetPreview.GetMiniTypeThumbnail(type);
    }
    else
    {
        s_ObjectContent.text = "<no type>";
        s_ObjectContent.image = null;
    }
    return s_ObjectContent;
}

pass instanceID of -1 to get "Missing" and instanceID of 0 to get "None"

I don't know if Unity ever uses the instanceIDs -1 and 0 for internal stuff tho
haven't seen it so far, but who knows 😅

[onyx harness]

0 is by default a none existing object

So pretty sure it is widely used in their codebase

[patent pebble]

i mean if they only use it for a non-existing object it should be fine

[onyx harness]

We use -1 for a natural non-used ID, but perhaps 1, 2, 3, etc. are also missing ones 🙂

[patent pebble]

seems safe enough then

if it ever makes my Unity explode i'll share the cautionary tale 🙃

[eternal surge]

Hi, I've made a little extension to add object arrays similar to the ones in blender. Not the first of its kind, but this is mine :)

[visual yacht]

Hello 🙂
I would like to understand how to implement undo in the editor
I want to replace GameObjects from the scene with prefabs

I have a editor script with this sequence within a method:

foreach ( GameObject sceneGameObject in selectedObjectsInScene){
  PrefabGameObject = GameObject.Instantiate(GameObjectReplacement) as GameObject;
  Undo.RegisterCreatedObjectUndo(PrefabGameObject, "created object");

  PrefabGameObject.transform.position   = sceneGameObject.transform.position;
  PrefabGameObject.transform.rotation   = sceneGameObject.transform.rotation;
  PrefabGameObject.transform.localScale = sceneGameObject.transform.localScale;
  PrefabGameObject.transform.parent = sceneGameObject.transform.parent;  

  Undo.DestroyObjectImmediate(sceneGameObject);
}

Everthying works as intended, but Unity crashes when hitting ctrl+z after running the script.
It seems the problem comes when calling Undo.RegisterCreatedObjectUndo(..) as when I comment it out, unity does not crash anymore

any ideas?
I am not sure the explanations on in the manual can help me ( https://docs.unity3d.com/ScriptReference/Undo.html)

[gloomy chasm]

I think it looks okay... Simply for a readability thing I would change PrefabGameObject to be defined where it is instatiated, so GameObject prefabInstance = (GameObject)GameObject.Instantiate(GameObjectReplacement);

You also want to combine all of the undo operations in to one so that when you perform an undo/redo all of the gameobjects will be destroyed and created in the same operations

int undoGroup = Undo.GetCurrentGroup();

// foreach loop here...

Undo.CollapseUndoOperations(undoGroup);

[patent pebble]

just a random guess, your Editor may be crashing because you are destroying an object that is part of the undo operation?

try to do the PrefabGameObject.transform.position, etc lines before the RegisterCreatedObjectUndo and see what happens

[visual yacht]

this is a nice idea. i will try and implement it

[visual yacht]

hey, this one did the trick!
now it works properly, thank you very much

[patent pebble]

i actually had no idea if that was the problem, just a random guess 😅

glad it's working

[gloomy chasm]

I am trying to find a way to not use harmony for this thing I am doing. And I almost have found a way....
Not for the first time I have wished I could inherit from an internal class 😢

[patent pebble]

what ya doing exactly?

[gloomy chasm]

I am working to finish my ScriptableObject Variants asset, and need to support VisualElements showing the override.

[patent pebble]

sounds like one of those things that seems simple enough but then Unity does a 360 on you

"pls unity stop being unity"

😢 ...

[onyx harness]

Harmony in an asset in the Asset Store is dangerous, hope you will go through

[gloomy chasm]

There is a VisualTreeUpdater that takes a list of IVisualTreeUpdater and does exactly what I want... if I could implement IVisualTreeUpdater in a class

[patent pebble]

is Harmony considered against terms of service? I know it's a tool modders use to hack code into games and stuff

[gloomy chasm]

Yeah, I think I can find a way to make it work without it. I would really prefer not to use Harmony in an asset, especially since it is not 'mission critical' for the asset to function

I know some assets use it. Like the Needle guys just released an asset that uses it I know

[remote yarrow]

1. There are magic methods you're supposed to use (that aren't mentioned in the main API docs - you have to know they exst before you can discover they exist ;)) instead of core methods if you want Undo to work correctly. There are replacements for (off the top of my head): .position, .rotation, .transform.parent, and AddComponent <-- the parent one is important and the addcomponent one is slightly important. You don't have to use them (apart from the parent one - not using that one causes actual problems) but they are worth using. Almost no-one knows about these, but then ... Undo doesn't work correctly for most assets so that's not a surprise 🙂
2. Unity wrote a one-class utility that makes Undo much easier to get right, and auto-compiles-itself-out of non-Editor builds. It's called "UndoBlock". It's here: https://docs.unity3d.com/Packages/com.unity.reflect@1.0/api/Unity.Labs.Utils.UndoBlock.html - you can get the source from their repo IIRC.
3. ...UndoBlock is missing some features/API calls required to fully implement Undo in Unity, so I use an extended version of that class (which I sent back to Unity, the changes might (?) have been incorporated), and now it's easy to make Undo work in new assets/projects.

I've been filing bugs on Unity's Undo implementation since approx 2014. I consider it an embarassment that it was never really tested or designed.

[gloomy chasm]

What magic methods do you mean...? As far as I know there are no 'undo alternatives' for setting the position or rotation.

Undo doesn't work correctly for most assets
What do you mean? Do you mean that most assets don't implement it properly, or that Undo doesn't allow functionality that would support most assets?

Man that Unity.Labs package has so many handy utilities! Too mad it is not on github 😦
The undo block is pretty basic right? Just a get and collapse the undo group, no?

[remote yarrow]

IME: Most assets don't implement Undo correctly. You can undo some actions but not all, or you can undo 'everything' or 'nothing' but not 'the actual steps I performed, in reverse order'. etc.

The undo block is circa 300 lines of code, so I guess basic yes?

[gloomy chasm]

Yeah, most assets don't. Which is funny because it is a requirement to be on the store...
I disagree, you can implement Undo just fine, you just register an undo before each change. That is exactly how it is designed to be used
(Whether that is a good design or not is very much so up for debate though haha)

[remote yarrow]

No, it's not how it's designed, sadly

That simply won't work a lot of the time

It's things like: do you remember to never do "transform.parent = X" and instead do "Undo.SetTransformParent( X )"?

Simple cases today mostly work (although one bug I filed a few years back was "create a cube, rotate it once, move it with the mouse, hit ctrl-z, and undo breaks" with core UnityEditor 😄 )

[gloomy chasm]

I am pretty sure that is the only exception to the rule

[gloomy chasm]

Uhh... they how is it designed?

Can you give an example of where undo won't work?

[remote yarrow]

If it were designed simply then we wouldn't need most of the API, we'd only need a couple of method calls, they would work in all situations, and there'd be no excuse for any asset to be missing full Undo support

In practice it's: do it simply, discover the MANY cases that break in-editor, play whack-a-mole trying different combinations of API calls to try and force the Editor to honour the API, play whack-a-mole some more re-writing your code in ways that should make no difference but do make the Editor Undo system work / stop working ... etc

(and, of course, every method call has to be #if UNITY_EDITOR because none of the API calls are allowed in runtime code)

TL;DR: it's a mess

[gloomy chasm]

What the heck are you doing...?!

If you are trying to use undo in runtime classes (like components) you are using undo and editor scripting wrong...

[remote yarrow]

Any change to any data that can be triggered from inside the editor needs to be wrapped in undo logic. If your editor menu does something that uses your runtime components/code/etc ... and you don't insert/wrap all the Undo cases ... it will screw up. The code will run fine in runtime and Editor, but Editor will fail to Undo (sometimes you get 'nothing happens', but about 1/3 the time you get 'Unity corrupts the scene' by making weird random changes to MonoBehaviour data)

(corruption that - of course - can't be undone using ctrl-z; it's 'git checkout --' time again)

[gloomy chasm]

When editor scripting you should almost never need to use #if UNITY_EDITOR

[remote yarrow]

TL;DR: if Undo is simple, and works as designed -- why did Unity staff feel the need to make a wrapper for it that makes it easier to use? 🙂

[remote yarrow]

Gizmos and Undo are the two places I keep having to do it, on project after project. Off the top of my head there aren't any others

[gloomy chasm]

It is literally basically just this.

public class UndoBlock : IDisposible
{
  private int undoGroup;
  public UndoBlock()
  {
    undoGroup = Undo.GetCurrentGroup():
  }

  public void Dispose()
  {
    Undo.CollapseUndoOperations(undoGroup)
  }
}

[gloomy chasm]

What, why?? What is the use-case for having Undo in runtime scripts?
(Gizmos are already in the UnityEngine namespace so you don't need them in #if UNITY_EDITOR right...?)

In general if you are changing properties of a runtime object, you should be using SerializedObject to do it not calling the APIs.

[remote yarrow]

Gizmos have no meaning at runtime. But Unity requires the (editor-only) code for gizmos to go inside runtime classes. If you constrain yourself to the crappy/ugly Unity-3.x era editor extensions then, sure, you'll be OK. But if you want to do anything particularly valuable/interactive it usually means interacting with Editor APIs sooner or later.

[gloomy chasm]

The Gizmos class should work in build unless I am wrong (not visible, but won't stop the build)
Most of the time, if you are doing something with a Editor API, then you should be doing it in an editor specific class. There are some cases where that is not the case, normally those have to do with the asset database in some way, but general editor code goes in editor class

[remote yarrow]

I tried that approach. It's insane. It will kill you. The amount of code duplication is incredible (I recently refactored an 8 year old editor extension that was built that way - So. Many. Bugs! due to code duplication).

Or: I have an extension that was originally editor-only, but users required it to be also available at runtime. That was painful to change.

[gloomy chasm]

It depends on what you are doing, but there should be that much duplication. Either way, that is the way that Unity designed it to work.
If you don't like doing it that way that is fine, but it isn't fair to say that something like Undo doesn't work well when you are not using it as intended.

Not saying the design is perfect, but it does function well and covers any use-case as long as you are using UnityEngine.Objects

Editor code should basically be treated like the view and controller in an MVC (assuming I remember the MVC properly)
Where the runtime stuff is the model

[onyx harness]

https://docs.unity3d.com/ScriptReference/Undo.html
What do you call main API docs?

[gloomy chasm]

Is there a decent way to get the folder for your asset?
Right now I am doing this and it feels really dirty

internal class EditorAssetsFolderLocator : ScriptableObject
{
  /// <summary>
  /// Reterns the project reletive path to the "MyAsset/Editor" folder in the assets folder.
  /// </summary>
  public static string GetFolderPath()
  {
     var locator = CreateInstance<EditorAssetsFolderLocator>();
     var script = MonoScript.FromScriptableObject(locator);

     string path = Path.GetDirectoryName(AssetDatabase.GetAssetPath(script));
     if (Path.DirectorySeparatorChar != '/')
        path = path.Replace(Path.DirectorySeparatorChar, '/');

     DestroyImmediate(locator);
     return path;
   }
}

[patent pebble]

@gloomy chasm you can use the [CallerFilePath] attribute or a StackTrace

private static string GetFolderPath1(bool projectRelative = true, [CallerFilePath] string filePath = "")
{
    filePath = Path.GetDirectoryName(filePath);
    filePath = MakePathUnityStyle(filePath);

    if (projectRelative)
    {
        filePath = MakePathRelative(filePath);
    }

    return filePath;
}

private static string GetFolderPath2(bool projectRelative = true)
{
    string filePath = new StackTrace(true).GetFrame(0).GetFileName();
    filePath = Path.GetDirectoryName(filePath);
    filePath = MakePathUnityStyle(filePath);

    if (projectRelative)
    {
        filePath = MakePathRelative(filePath);
    }

    return filePath;
}

private static string MakePathUnityStyle(string path)
{
    return path.Replace(Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar);
}

private static string MakePathRelative(string path)
{
    return path.Replace(Application.dataPath, "").Insert(0, "Assets");
}

[onyx harness]

typeof(EditorAssetsFolderLocation).Assembly.Location perhaps

works for AsmDef, which might link to Library, crap

[patent pebble]

yeh

D:\Unity\MyProject\Library\ScriptAssemblies\MyAssembly.dll

[onyx harness]

I'm using this to fetch from a Type:
https://gist.github.com/Mikilo/bbeda90ed7125a35a11cbcaab6aa6e39

Which basically uses your trick, but has fallbacks

[gloomy chasm]

So basically, there isn't really a nicer way to do it :/

[onyx harness]

But my utility is mainly to extract GUID & LocalID

If

If you rely on "C# Type must match its filename"

You can use this:

static class PrintAssembliesSources
{
    [MenuItem(Constants.PackageTitle + " Internal/Print Assemblies Sources")]
    public static void Print()
    {
        var    list = Client.List(
#if UNITY_2018_1_OR_NEWER
            true
#endif
        );

        while (list.IsCompleted == false);

        foreach (var item in list.Result)
            NGDebug.Snapshot(item, item.packageId);

        Assembly[]        playerAssemblies = CompilationPipeline.GetAssemblies();
        StringBuilder    buffer = Utility.GetBuffer();

        foreach (Assembly assembly in playerAssemblies)
        {
            NGDebug.Snapshot(assembly, assembly.name);

            buffer.Length = 0;

            for (int i = 0, max = assembly.sourceFiles.Length; i < max; i++)
                buffer.AppendLine(assembly.sourceFiles[i]);

            Debug.Log(buffer.ToString());
        }
    }
}

Which gives you the the .cs for any Asm

Not very reliable

I mean, you can't handle duplicate

I know there is another way to get scripts, but I forgot, someone mention another way on the publisher Discord or the forum, I don't recall

[onyx harness]

But the StackTrace should work pretty decently

[patent pebble]

i can't say how reliable it is because I'm not super experienced in this topic
but so far for me it has been working fine, and it's relatively clean

using the [CallerFilePath] works fine too, but you have to wrap the method in another method or you will get a different path if the method with the attribute is called from an external script

so

public static string GetFolderPath(bool projectRelative = true)
{
    return GetFolderPath(projectRelative);
}

private static string GetFolderPath(bool projectRelative, [CallerFilePath] string filePath = "")
{
    filePath = Path.GetDirectoryName(filePath);
    filePath = MakePathUnityStyle(filePath);

    if (projectRelative)
    {
        filePath = MakePathRelative(filePath);
    }

    return filePath;
}

which is kinda boilerplate-ish

i just keep both examples just in case one of them doesn't work for some reason

[onyx harness]

StackTrace is pretty reliable, we all rely on it when writing a console

[gloomy chasm]

Yeah, seems like StackTrace might be a good idea. I will give it a try, thanks Madled

[onyx harness]

Don't forget to cache to keep it efficient

[gloomy chasm]

@onyx harness well... it took ~5 hours but I finally managed to remove harmony! 😄

Trying to follow the code for how Unity handles it was such a pain. You know how it is, both trying to understand the implementation and also look to see how you can hook in to it

Such a pain

[remote yarrow]

The MonoScript was broken in 2020 (they only just fixed it today), so we moved over to using the Assembly trick. However it requires a bit more work than just grabbing the Assembly - you need to handle special cases of "am I in a local Package? (because file locations there aren't writeable, and you usually need to know that!)", and "am I in a DLL? (because I got slightly different results on this one - but there's a Unity API for working around this specifically)"

Manually copying from other machine (IDE on this machine doesn't have that checked out):

var asm = Assembly.GetAssembly(GetType)).GetName().Name;
var asmDef = CompilationPipeline.GetAsssmeblyDefinitionFilePathFromAssemblyName(asm);
var asmDLL = CompilationPipeline.GetPrecompiledAssebmlyPathFromAssemblyName(asm);
if( asmDLL == null ) asmDLL = CompilationPipeline.GetPrecompiledAssebmlyPathFromAssemblyName(asm+".dll"); // yes, really - Unity's API a bit wonky here
var pathForAssembly = asmDef ?? asmDLL;

... which gives you a reliable root position, and then you can navigate relatively

[gloomy chasm]

Using the MonoScript works fine for me in 2020.3 and newer. I think I will either keep using that or try out the StackTrace method as that seems a bit cleaner. Thanks for the heads up about the assembly method though!

@honest crater wrong channel. This belongs in #⚛️┃physics or #💻┃code-beginner / #archived-code-general

oh sorry didnt realize

[gloomy chasm]

When deleting an asset, you get a prompt like this.
Does anyone know of a way to show my own prompt instead?

[patent pebble]

@gloomy chasm yes! i've made a similar prompt for an asset processor

gimme a sec

ah whoops

misread

i don't know how to override the default prompt

😓 ...

[gloomy chasm]

ooh 😦

Shoot... I don't think there is a way without using Harmony, but I just got rid of it!

Maybe I can try intercepting the key down event in the project browser?

Its not perfect...

It's so silly. Getting SO variants to actually function has taken the least hacking (meaning none) while adding all this 'extra' stuff has taken so much xD

[patent pebble]

the devil is in the details

i get super bogged down by so many little menial things like that too

[gloomy chasm]

Getting sidebars to work took less hacking than this

Well.. no that's not really true since it is almost 100% reflection... but still!

[onyx harness]

What are you trying to do?

[gloomy chasm]

Instead of showing the normal prompt when deleting an asset, I want to show one like this

But for scriptableObject variants of course

[onyx harness]

Sounds tricky & dificult 🙂

[drifting summit]

im trying to impliment the ReadOnly attribute, and it works for classes inside the editor script, but my other normal scripts dont recognize it. I have the editor script in the Editor folder. Am i missing a step?

[eager shale]

so there's the EditorGUILayout.FloatField() and for other types as well, but where is the boolean version of it?

nvm it's .Toggle()

[gloomy chasm]

You need the file where the attribute is defined to not be in the editor folder

[drifting summit]

then what goes in the editor foldeR?

[gloomy chasm]

The code for drawing

You have public class ReadOnlyAttribute : PropertyAttribute { }

And that does not go in the editor folder

[drifting summit]

i see

[gloomy chasm]

your class that inherits from DecoratorDrawer does go in the editor folder

[drifting summit]

i was able to fix it thanks to you

[gloomy chasm]

LOL, I was trying out the new Splines tool and learned that the property drawer uses a naive implementation to get the value of a serialized property just using the property path
That means you can't have a Spline field in another class or list xD

[tired basalt]

Is there anyways to update nested prefab but do not trigger reimport of father prefab?

Or at least, reimport later

How to build a project with editor script without deleting?

Oh, ok. Thank you very much

[lethal sage]

So I am making an extension for my game that procedurally generates a roof made of convex sections based on some control points (child gameobjects). I'm using handles to allow easily moving the points. Moving the handle updates the point's position and regenerates the roof. How do I solve the following issues?:

1. An undo operation should only be made when the point begins being moved, not every frame while it is moving (currently I'm storing last saved time and checking if it's been more than a second).
2. Undoing/redoing a control point movement should regenerate the roof.

[patent pebble]

when accessed through a SerializedProperty, why is this class considered a Generic and not an ObjectReference?

[Serializable]
public class SomeClass {}

[gloomy chasm]

Because it does not inherit from UnityEngine.Object

[patent pebble]

ah

makes sense

stupid me 💀

[gloomy chasm]

All good. I've been there

[patent pebble]

is it safe to use UNICODE characters in Unity?
such as this (U+27F6)

⟶

i have been scared of using them because I don't know if they will display inconsistently or if they will break under certain conditions

[twin dawn]

Using them where?

[patent pebble]

in the Editor UI

such as the inspector panel or any EditorWindow

[gloomy chasm]

Yes, for one the PackageManager uses them for the sort order dropdown button

[patent pebble]

oh, interesting

[terse hazel]

[Serializable]
public sealed class SceneRef
{
    [field: SerializeField] public string ScenePath  { get; private set; }
    [field: SerializeField] public int    BuildIndex { get; private set; }
    
    public static implicit operator string (SceneRef reference) => reference.ScenePath;
    public static implicit operator int    (SceneRef reference) => reference.BuildIndex;
    
    #if UNITY_EDITOR

        private const string _BUILD_INDEX = nameof(BuildIndex);
        
        public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
        {
            SerializedProperty _scenePathProperty  = property.FindPropertyRelative(relativePropertyPath: _SCENE_PATH);
            SerializedProperty _buildIndexProperty = property.FindPropertyRelative(relativePropertyPath: _BUILD_INDEX);
```Any reason why `_scenePathProperty` and `_buildIndexProperty`  are null?

Can **property**.Find**Property**Relative not find properties?

[gloomy chasm]

Because ScenePath is not the name of the field that is serialized, it is the backing field which is serialized

And no, FindPropertyReletive some what paradoxically cannot find c# properties. Only public fields and private fields with the [SerializeReference] attribute since those are the only field types that Unity serializes

[visual stag]

$"<{nameof(ScenePath)}>k__BackingField" would be how to get the serialized backing field from a property

it's not nice, so it's best to just serialize backing fields

[uneven pebble]

I was wondering if I can have a bunch of CreateCustomGameObject in a separate static class(es). Of course with different method names, as long as the [MenuItem()] directive made the editor recognise those methods?

Is that possible? Or do I need to keep them in the Monobehaviour derived classes?

[supple willow]

hey. how can i set some Editor local method to be called right after load ?

I want to subscribe to onHierarchyChanged as soon as possible

EditorApplication.hierarchyChanged += onHierarchyChanged;```

but the soonest thing I know is OnEnable, which is not good, because its only called when someone clicks on the gameobject with that script

[honest bramble]

I'm trying to learn about ScriptedImporter as I have a file with a unique extension that contains data for various meshes. In my OnImportAsset(AssetImportContext ctx) method I'm able to make children and components (MeshFilter and MeshRenderer for exmaple) to the object, but for some reason no matter how I make Meshes and assign them to the MeshFilter.mesh property, the file never shows the meshes. When I attempt to use the example code on the API it does properly show a primitive cube for the GameObject though. Any help appreciated. Thanks!

    [ScriptedImporter(1, "XPR")]
    public class XPRImporter : ScriptedImporter {
        public Mesh[] meshes;

        public override void OnImportAsset(AssetImportContext ctx) {
            GameObject root = ObjectFactory.CreateGameObject(Path.GetFileNameWithoutExtension(ctx.assetPath));
            root.transform.position = new Vector3(0, 0, 0);
            GameObject meshRoot = ObjectFactory.CreateGameObject("MDL");
            meshRoot.transform.position = new Vector3(0, 0, 0);
            meshRoot.transform.SetParent(root.transform);

            GameObject mesh = ObjectFactory.CreateGameObject("OBJ");
            mesh.transform.position = new Vector3(0, 0, 0);
            mesh.transform.SetParent(meshRoot.transform);
            MeshFilter meshFilter = ObjectFactory.AddComponent<MeshFilter>(mesh);
            MeshRenderer meshRenderer = ObjectFactory.AddComponent<MeshRenderer>(mesh);();

            meshes = new Mesh[1];
            meshes[0] = new Mesh();
            meshes[0].Clear();
            meshes[0].vertices = new Vector3[] {
                new Vector3(0, 0, 0),
                new Vector3(0, 0, 1),
                new Vector3(1, 0, 0)
            };
            meshes[0].triangles = new int[] { 0, 1, 2 };
            meshFilter.mesh = meshes[0];
            ctx.AddObjectToAsset("main", root);
            ctx.SetMainObject(root);
        }
    }

[waxen sandal]

You probably need to dirty the meshfilter

[terse hazel]

I guess I'll create a utility function for that amd test it out, thanks guys!

[honest bramble]

How would I do that?

[gloomy chasm]

Not sure what you are talking about exactly, but yes.

[gloomy chasm]

Lookup the InitializeOnLoad attribute

[uneven pebble]

Creating additional entries under 'GameObject' in the heirarchy context menu

There or anywhere else for that matter

[gloomy chasm]

Oh, yeah you can

[honest bramble]

Did a EditorUtility.SetDirty(meshFilter); call and it didn't alter the results.

[honest bramble]

Also I get the following error on import if I have public Mesh[] meshes; Line in the class like in Ln3 of my example. I don't understand why, even if I don't do anything with it:

NullReferenceException: Object reference not set to an instance of an object
UnityEditor.PropertyHandler.IsArrayReorderable (UnityEditor.SerializedProperty property)

[snow bone]

[primal steeple]

Anyone know whether to use PreviewRenderUtility over GUI.DrawTextureWithTexCoords when trying to make an editor that's similar to the animation window?

[patent pebble]

yes, with reflection, Unity has this internal delegate

internal static CallbackFunction globalEventHandler;

you can access the information of a KeyDown and KeyUp using that

https://github.com/Unity-Technologies/UnityCsReference/blob/master/Editor/Mono/EditorApplication.cs#L268

it also has this one, to check if a shortcut is triggered

internal static Func<bool> doPressedKeysTriggerAnyShortcut;

[patent pebble]

here's an example on how to use them

public static class GlobalKeyEvents
{
    // Exposed delegates to hook up your methods to them.
    public static event Action<KeyCode, EventModifiers> GlobalKeyDown;
    public static event Action<KeyCode, EventModifiers> GlobalKeyUp;
    public static event Action AnyShortcutTriggered;

    [InitializeOnLoadMethod]
    private static void EditorInit()
    {
        RegisterToGlobalEventHandler();
        RegisterToTriggeredAnyShortcut();
    }

    private static void RegisterToGlobalEventHandler()
    {
        FieldInfo info = typeof(EditorApplication).GetField("globalEventHandler", BindingFlags.Static | BindingFlags.NonPublic);
        EditorApplication.CallbackFunction value = (EditorApplication.CallbackFunction)info.GetValue(null);
        value += OnGlobalKeyPressed;
        info.SetValue(null, value);
    }

    private static void RegisterToTriggeredAnyShortcut()
    {
        FieldInfo info = typeof(EditorApplication).GetField("doPressedKeysTriggerAnyShortcut", BindingFlags.Static | BindingFlags.NonPublic);
        Func<bool> value = (Func<bool>)info.GetValue(null);
        value += OnAnyShortcutTriggered;
        info.SetValue(null, value);
    }

    private static void OnGlobalKeyPressed()
    {
        if (Event.current.type == EventType.KeyDown)
        {
            GlobalKeyDown?.Invoke(Event.current.keyCode, Event.current.modifiers);
        }
        else if (Event.current.type == EventType.KeyUp)
        {
            GlobalKeyUp?.Invoke(Event.current.keyCode, Event.current.modifiers);
        }
    }

    private static bool OnAnyShortcutTriggered()
    {
        AnyShortcutTriggered?.Invoke();
        return true;
    }
}

however, the doPressedKeysTriggerAnyShortcut delegate seems like it doesn't trigger for EVERY shortcut, like for example Ctrl + R or Ctrl + C don't trigger it
so you probably want to rely more on the globalEventHandler to manually check for your key combinations

[cinder relic]

I think the handles class should "handle" that for you

Is there a way I can add a MenuItem without using the attribute?

[outer kraken]

I don't think so, what would be your preferred way to make them?

[mossy wren]

You seem like you know your stuff... But I got some errors, probably easy to fix for you.

[patent pebble]

you need to use the namespaces where those types are in

with the "using" directives like

using System;
using UnityEngine;
etc...

if you press "CTRL + ." while the caret (cursor) is on top of those errors in Visual Studio it should give you a list of recommended fixes

one of them will be to import the namespaces

[north sphinx]

Any idea whether you can make editor window top part to be windows style? not this one that snaps only inside unity

just like main unity window

like that

[harsh hull]

Good question, I’d like to know too. I doubt it though

[patent pebble]

@north sphinx @harsh hull yes, search the documentation for EditorWindow, it has multiple ''Show...'' methods to show the window in different ways

Normal, utility, etc

I don't think you can change the style of the default windows like the scene, inspector, etc

Or at least i dont know how

But you can show your own windows however you like

[north sphinx]

that sucks

I'm only interested in vanilla windows

[waxen sandal]

There's the Wizard thing that has the normal windows bar

[patent pebble]

ah I'm stupid, you actually can show the default windows however you like too

you can't change the already existing ones, you have to create a new instance

@north sphinx but you will lose the functionality that comes with the top bar buttons like the lock and the context menus

[north sphinx]

wait, what do I click in that context menu?

to open window as separate window

[patent pebble]

no, i mean with the other styles like the ShowUtility, you will lose those top bar buttons

to open the windows as extra instances with the different styles you need to use CreateInstance

one sec, i'll share example

using System.Linq;
using System;
using UnityEditor;
using UnityEngine;

public class ShowsWithDefaultWindows : EditorWindow
{
    private EditorWindow[] _foundWindows;

    private int _selectedIndex;
    private string[] _popupOptions;

    [MenuItem("Something/Default windows Show test")]
    public static void MakeWindow()
    {
        GetWindow<ShowsWithDefaultWindows>();
    }

    private void OnGUI()
    {
        // Get all windows
        if (GUILayout.Button("Get all open windows"))
        {
            _foundWindows = EditorWindowUtility.GetAllWindows();
            _popupOptions = _foundWindows.Select(window => window.GetType().Name).ToArray();
        }

        // Draw popup, button and labels
        if (_foundWindows != null && _foundWindows.Length != 0)
        {
            _selectedIndex = EditorGUILayout.Popup(_selectedIndex, _popupOptions);

            if (GUILayout.Button($"Call ShowUtility on: {_popupOptions[_selectedIndex]}"))
            {
                EditorWindow newInstance = CreateInstance(_foundWindows[_selectedIndex].GetType()) as EditorWindow;
                newInstance.ShowUtility();
            }

            for (int i = 0; i < _foundWindows.Length; i++)
            {
                EditorGUILayout.LabelField(_foundWindows[i].titleContent.text, $"Type: {_foundWindows[i].GetType()}");
            }
        }
        else
        {
            EditorGUILayout.LabelField("No found windows");
        }
    }
}

i have no idea if there's unintended consequences of showing the default windows in that manner...
because Unity... you know 🙃
so use at your own risk

ah forgot to share the utility method

public static class EditorWindowUtility
{
    public static EditorWindow[] GetAllWindows()
    {
        return Resources.FindObjectsOfTypeAll<EditorWindow>();
    }
}

[north sphinx]

wow, thanks

let's see how it works

yep, it is indeed opened in windows style window

but, is it possible to do it with exactly this style?

that has minimize/maximize

and x to close

like main Unity window

Mainly I want that because unity own windows are not snapping to screen

[patent pebble]

no idea to be honest
I haven't dug that far into this topic

maybe someone else knows

[patent pebble]

how aren't they snapping?

when I click "maximize" on mine they snap to the edges of the screen

[north sphinx]

like that, screenshot top is edge of screen

it just goes above, like unity window

[patent pebble]

@north sphinx i don't know what you mean exactly, both my main Unity window and the EditorWindows snap by default when doing maximize

EditorWindows don't snap by dragging like the main window does tho

🤷‍♀️

[north sphinx]

kinda that's what I mean, I dragged window partially into top side of screen and if I stop holding mouse, screen will maximize itself

editor windows don't do that

and that's what I aim for

[slender jetty]

Hi 🙂 I am looking for a bit of help/insight in setting up my ability system. One of the things I would like to be able to do is create them as scriptable objects and edit them in the inspector, rather than having to program each of them individually. What I am considering right now is having a custom editable list of steps to happen when the ability hits (abstract class AbilityStep). Would it be possible to make a list like this, but with an abstract object type, rather than one all incompassing class with all the values needed for all of them?

I had this in a previous project, but I just don't find it very configurable/changable

[gloomy chasm]

I don't really understand what you are asking, but yeah, you can use polymorphism if that is what you mean.

[slender jetty]

Does it work smoothly for saving and reloading them?

If I have a list of objects that all inherit from the same type?

[gloomy chasm]

Yes if you use the [SerializeReference] attribute instead of [SerializeField]

[slender jetty]

Cool 🙂 Thanks

[slender jetty]

On a SerializedProperty, is there a way to see all available children?

namespace Abilities.Steps
{
    [Serializable]
    public class AbilityStepList
    {
        public List<AbilityStep> Steps;
    }

    [Serializable]
    public abstract class AbilityStep
    {
        public abstract bool DoStep();
    }
}

When I am making my propertyDrawer for this, I can't access Steps? I also can't get it to work with SerializeReference?

[CustomPropertyDrawer(typeof(AbilityStepList))]
public class AbilityStepListDrawer : PropertyDrawer
{
    public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
    {
        var list = property.FindPropertyRelative("Steps");
        return Mathf.Max(list.arraySize, 1) * 90 + 50;
    }
}

List is null in this case?

I would like to see if it can't find the property, or if the referenced property is null?

Oh, I got it working - SerializeReference on Steps, rather than on the class that has a AbilityStepList

[slender jetty]

In the above example AbilityStep is an abstract class - how can I add implementations of it to a reorderablelist that draws it?

[brazen willow]

what kind of extention do i need to make a ui like this and make it work in edit mode?
(image taken from another engine)

[mossy wren]

Works. Thank you! Now I can write scripts for the editor to make my compile cycles faster saving hours of work each day.

[gloomy chasm]

Look in the pinned messages

[brazen willow]

which one?

[gloomy chasm]

I guess I will break it down for you really quick.
Unity has two UI systems which you can use to create editor windows and inspectors.
Immediate Mode GUI (IMGUI)
This is the original way of make UI, it uses methods to draw the UI each frame much like an Update method in a component.

UI Toolkit (formerly UIElements)
This is the newer way and what will be used more and more as time goes on, it is a retained mode GUI (if you know what that means). It is based/inspired by web design so it uses USS and UXML files to define the structure and style of the UI.

[brazen willow]

sounds like IMGUI is more for me this time

[gloomy chasm]

Alrighty, then in the pinned messages look for "IMGUI Resources" 🙂

[brazen willow]

i did as it shows in unity document
but nothing popped up on the screen

[mossy wren]

Is there a (using UnityEditor;) function that lets me know if the project code base has changed since last compile?
Like... I want to know if it can be refreshed or not

[gloomy chasm]

What do you mean? Unless you disabled the option Unity should automatically recompile any time the code changes

[mossy wren]

Right. Thats what I did. Now I can change code and bounce between editor several times and not have to needlessly recompile every time

it saves about an hour of dev time a day.

Never mind, found a work around

[slender jetty]

When I try to open Amount here, it crashes with this description:

Hi, is there a command or the like to select previous asset, essentially a command that functions like a back button?

So I'm inspecting a material then click on a prefab. Is there a built in command to get back to the material I was originally inspecting?

[waxen sandal]

No but there extensions that do that mikilo's NG tools have one iirc

[terse marsh]

Had a question earlier that I deleted, I'll try to rephrase it: We're making an Isometric game using Tilemaps and I'm having issues with sorting layers so that the player is properly rendered in front of/behind objects like walls and pillars that they can be expected to both be behind and in front of

Instances like this, I can stand behind this wall but I want it to render properly when you're in front of it too

right now, that looks like this

Would there be a way to dynamically solve this in code? Like, checking whether or not the player is in front of or behind specific parts of the Tilemap? I know you're able to do that when referring specifically to singular objects with singular Sprites but since the Tilemap object isnt just a single square thats not going to work

[terse marsh]

Found this in an old forum thread https://forum.unity.com/threads/isometric-tilemap-sorting-issues.554914/#post-3692299

That if I put everything on the same layer, itll dynamically sort itself out

is this the only way to solve it? Feels like itd lead to issues later

[snow bone]

is it possible to create a property drawer for an editor class and not a monobehaviour?

would i need to perhaps serialize the editor window class. I'm using a custom editor that I want to display something in, which is what the property drawer would be for displaying; a property in the custom editor window.

Should I perhaps create a serialized container class for stuff I want to be display in the property draw?

you should be able to use the filter to search for classes of the animationcontroller

code-advanced is probably a better channel

[timber vapor]

thanks

[gloomy chasm]

What do you mean?

[snow bone]

@gloomy chasmi'm trying to have a docked previewRenderUtility window at the bottom of my editor, but don't know how to dock it, so considered making a property drawer to display it. Ie, the Cube window in the image below would show a previewRenderUtility window of what's in the Fbx Model field

that's a cut & paste, I don't know how to make the docked cube window thing at the bottom attach to my editor. This is what I want it to be.

I have the previewRenderUtility code to display what I want, but it's in it's own window

this is what have

Anyone know how to add an Apply and Revert buttons to the inspector of a ScriptedImporter, I have booleans in the Editor Window but I have to Right-click > Reimport every time, instead of doing an Apply like an FBX importer.

[patent pebble]

yes

there's all the relevant API methods

i threw a couple extra just for good measure

[honest bramble]

Much appreciated

@patent pebble sadly, even after adding a protected override bool needsApplyRevert => true; and in the protected override void OnInspectorGUI() { } I add the ApplyRevertGUI(); call, neither button shows.

that's for static methods. I specified I'm looking for a way to call local methods. but thatnks anyways

OnEnable is called right after an editor instance is loaded

Discovered recently that an EditorWindow invokes OnFocus before OnEnable on initialization

Oh cool

[worldly echo]

Heyllo people, How may I display an int value in the custom editor of a ScriptableObject ?

[barren moat]

Hey did you get this working? I was dealing with this today. The solution is to set the custom sorting axis for your camera to (0, 1, 0). I believe for a tilemap you need to set it to render individually instead of batch mode.

You'll also need to make sure the pivot point of your sprites is at bottom center as that's the position that is considered when sorting.

How to run code on Update in editor only?
Basically, I'm making my own custom renderer for niche cases and I need to create a preview in scene view to adjust colliders/scale/positions
Which is pepega hard without any view.
So I simply want to run some code on Update

but only for editor

[waxen sandal]

EditorApplication.Update?

[north sphinx]

I have no idea

I need it to run from mono behaviour

[waxen sandal]

ExecuteAlways/ExecuteInEditor?

[north sphinx]

hmm, maybe it is

yeeep that is it

thank you

hmmm

what about isolated view in Prefab editor?

for some reason in prefab editor my code is not running

I do it in update()

[pine geyser]

I have tried to make a custom unity inspector for a thing I made and I am overriding the regular rendering to have it drawn as a grid of toggles(images actually but still toggles) but seems like any changes I make don't get saved to the disk. only in memory

so I have a Scriptable object containing an array of booleans and not sure how I am supposed to modify it so it gets saved

[waxen sandal]

Use SerializedObjects instead of direct object access

[pine geyser]

something like?
var myThing = (MyObjectType) serializedObject.targetObject;

it gets my data, I modify it but how do I save it?

serializedObject.ApplyModifiedProperties(); doesn't seem to do anything

and I do Markdity on the target object

[waxen sandal]

You have to use the serializedobejct to modify it

rather than using targetobject

[pine geyser]

sorry but idk how to use it

[waxen sandal]

that's why there's google

[pine geyser]

I don't have good google skills

[waxen sandal]

you better learn then

If you google Unity Serialized Object, you probably find an example of eactly what you want

[pine geyser]

var array = ((UnitRange) serializedObject.targetObject).grid;
array[3] = true;

EditorUtility.SetDirty(_property.serializedObject.targetObject);
_property.serializedObject.ApplyModifiedProperties();

that's rougly what I do rn

seems like it's saving the stuff but only when I hit save on the scene

Kinda works but kinda sucks I need to hit ctrl save after hitting the save button in my editor

[karmic ginkgo]

Thanks both of you

now it works

Hi everyone, quick question, I am currently using EditorGUI.ToggleLeft, is it possible to make it have this state?

Or what sort of toggle should I use/should I cheese it by drawing that on top of the inactive toggle

[visual stag]

 EditorGUI.showMixedValue = true;
 bool value = EditorGUILayout.Toggle (...);
 EditorGUI.showMixedValue = false;```

Hello so I am working on an Editor Themes asset that lets you change the default look of unity. However I have a bit of trouble changing the color of buttons. I can change almost anything using an uss just buttons don't work ```css
.button

background-color: #000000;
}

I'm trying to setup a progress bar but this only goes to 2/5 th of the loading bar, the rest after "Iter_2" stays in the same place. Any ideas why?

 EditorUtility.DisplayProgressBar("ProgressBarTest", "Iter_1", 1f / 5f);
 Thread.Sleep(1000);
 EditorUtility.DisplayProgressBar("ProgressBarTest", "Iter_2", 2f / 5f);
 Thread.Sleep(1000);
 EditorUtility.DisplayProgressBar("ProgressBarTest", "Iter_3", 3f / 5f);
 Thread.Sleep(1000);
 EditorUtility.DisplayProgressBar("ProgressBarTest", "Iter_4", 4f / 5f);
 Thread.Sleep(1000);
 EditorUtility.DisplayProgressBar("ProgressBarTest", "Iter_5", 5f / 5f);
 Thread.Sleep(1000);
 EditorUtility.ClearProgressBar();

[waxen sandal]

Thread.sleep is not a good way to test that, wouldn't surprise me if that's causing issues

[outer ether]

updated the script to use x / 100f based values, after the reload it worked correctly, second time it got stuck again. So. yeah probably thread sleep

[hearty basin]

Hi everyone,

One my project growth, I need to better manage my project's assets. One solution i'm exploring is having two project : One for asset integration, and one for the project. To setup a functional pipeline using this method, I would like to develop a tool able to export UnityPackage from the "Asset only project" and automatically import it in the real game project. This will allow us to just add what we use in our project, but also have a nice way to update content without directly modifying source file.

But I need for this tool a script able to run a script from another project :
Export Package From "Asset project" -> Import Package in "Game Project". I've never seen a script able to communicate with another unity instance.
So my question is : Do you know if this is possible ? If yes, how would you do something like this ?

This is an experimental reflexion, and maybe there are some better way to handle this issue. So if you have any recommandation i would be happy to hear them.

Thank you !

[bright nova]

Hey folks,

Can anybody here firstly put up with my venting on how much I hate the fuzzy undefined behaviour of serialising unity assets and secondly please help me with fixing said flaky undefined behaviour. I'm going mad with deadline-looming but unitys-making-no-effing-sense crunchitis here.

[keen coral]

Hey, just go through and explain, then we'll see if we can be of any help ^^

[bright nova]

Sure, I'm creating materials and setting properties - essentially creating a copy of a material but using a slightly different shader with similar parameters.
If I create the materials one by one, it works OK but if I create them altogether it sometimes misbehaves and all the input textures to the material are set to 'none'.
I print out the contents of the material after creation each time and the values look fine but seeing it in unity: nothing.
I'm saving the asset, I'm calling 'AssetDatabase.Refresh();' like some sort of ritual against bad spirits but still this weird empty material behaviour.

[keen coral]

Do you tag the newly configured materials as dirty?

https://docs.unity3d.com/ScriptReference/EditorUtility.SetDirty.html

[bright nova]

yup

The trouble is, I have no idea when unity is doing anything and no control over it either.

[keen coral]

Can I see the code your are using?

[bright nova]

it's all a black box and that black box isn't doing what I expect it to

sure, one sec

            }
        }

[keen coral]

gimme a second to read that

You may want to put that CreateAsset at the end of your code.

I'm not 100% sure that CreateAsset links your attribute "mat" to the newly created asset.

From memory, I think you create the asset, and then you load it to deal with the actual asset (or you create the asset at the end).

You can safely discard most of those AssetDatabase Refresh ^.^ but I don't think they will cause any harm.

[bright nova]

Sorry, it's a bit long and there's some things in there that are hacky desperations around simply not understanding why the thing is doing what it's doing

[keen coral]

Sure, no problem.

[bright nova]

like ideally the second iteration through the 'gTextureMergeSpec' stuff shouldn't be necessary but that was me thinking that perhaps some late processing on the textures was resetting them, causing them to be nulled in the material later? No idea, it's all a black box.

[keen coral]

Try to load your material after creating it, instead of keeping the initial "mat" reference.

I think it's your best bet.

[bright nova]

ah, that's a trick I've used with textures

one sec

[keen coral]

From my own experience, when you start handling material assets, the usual problem is how to avoid them from saving things permanently, no the other way around 😁

[bright nova]

ha, well it could do with being clearer. Sometimes with this I feel less like I'm programming, more like I'm doing weird incantations and goat sacrifices to get the machine god to behave itself (n.b. have not actually hurt any goats)

[keen coral]

Also and this one is in case you are super tired, if for some reason the code goes through the "else" but you are super convinced that it doesn't, it obviously won't save anything.

[bright nova]

yeah, that's also a possibility, been doing late nights on this sprint. Holidays next week and they want it all working.

[keen coral]

Yeah Asset management in Unity is a bit related to dark voodoo, but it's not supposed to be blocking since the API is really small.

[bright nova]

I'd rather a REST style callback thingy when things are done.

[keen coral]

As long as you modify an asset, it should be fairly easy, so you should probably make 2-3 calls to assess what kind of instance you are handling.

[bright nova]

ohh, that sounds interesting - what are the different types of instance?

btw, that worked! Thank you - I should have guessed, like I said I had that idea with textures earlier but somehow didn't think to apply that lesson to materials.

[keen coral]

Ah great!

Well there are in-memory instances and asset instances, and that's about it.

One is just a temporary variable, and the other is linked to the disk.

Meshes, materials, etc. can be found in both types, depending of what you are doing.

[bright nova]

Ok, that's good to know. I knew that in memory assets were kinda temporary but must remember to reload them once saved.

[keen coral]

Yeah in the documentation it's not explained.

There are a fairly large number of holes on technicalities in Unity doc.

If they only added that in the doc, it would suddenly make a lot of sense ^.^

I'm guessing that if you tried to check the asset path of "mat" (before loading), you would have noticed that the path was empty 🤔

I'm not sure how to distinguish assets from instances except by knowing that they are 😁 but there must be a way.

[bright nova]

It would really help if they pointed just that little thing out, wouldn't it?

[gloomy chasm]

@bright nova @keen coral
Right-o, it seems like yall got it figured out, but I will go over a few things to try and make things clearer in the future.

Doing something like New Material(), new Texture(), and CreateInstance<ScriptableObject>() creates an instance of the class in memory.

You use AssetDatabase.CreateAsset(..) to serialize that instance in to a new file on disk.

AssetDatabase.Refresh() is used to update the UnityEngine.Object assets in the project from the serialized files.

AssetDatabase.SaveAssets() saves/serializes any changed UnityEngine.Object to file if they are dirty.
You use EditorUtility.SetDirty(..) to mark a UnityEngine.Object as dirty so that it will be saved.

Assets cannot contain (serialize) references to non-asset UnityEngine.Object as the way that it serializes the reference is using the GUID of the asset, of course non instances don't have a asset GUID.

Also you can use AssetDatabase.Contains(..) to know if an object is an asset or not.

[manic sandal]

Hey sorry I'm new here so feel free to let me know if this is asked wrong but I'm trying to override the way that a class is shown in inspector and haven't had any luck online. The goal is to show a class, for example a FancyInt differently when it is shown in inspector.

public class FanycInt : Monobehaviour
{
  public int fancyInt; // We'll do cool stuff to this later.
}

I can write a custom inspector so that when you add a FancyInt component to an object it show differently, but what I want is for the FancyInt to show up differently when another class is using it, for example

public class FancyIntContainer : Monobehavior
{
  public FancyInt myFancyInt = new FancyInt(); // I want to use a custom inspector for this!
}
``` 
I hope that makes sense, thanks in advance!

[gloomy chasm]

You mean you want a FancyInt field to show something besides the normal object field?

[manic sandal]

Yes

[gloomy chasm]

You want a PropertyDrawer https://docs.unity3d.com/ScriptReference/PropertyDrawer.html

[manic sandal]

Ah, awesome, didn't know how to look this up properly, thanks!

[gloomy chasm]

The USS class name for a button is .unity-button

[south fox]

Is this channel only about ui stuff? I want to do something when a scene gets opened in the editor (load another scene). I want to know if its possible and if so how to do it.

[slender jetty]

I have still not managed to find a solution to this? Anyone have experience with it? Opening a struct on my custom property drawer crashes the system.

[waxen sandal]

You got some code to show?

[slender jetty]

Sure, I can try doing a minimum. Is there a good place to put it?

[waxen sandal]

Hastebin or something similar

[slender jetty]

https://www.toptal.com/developers/hastebin/ugumepuvez.csharp <- Here. Note that the two "Damage" classes are in different namespaces normally

Forgot to include the actual class being drawn:

[Serializable]
public class AbilityStepList
{
    [SerializeReference]
    public List<AbilityStep> Steps;
}```

[gloomy chasm]

Okay, so I will just go over the things I see since I don't see anything obviously wrong off the bat.
You have a struct Damage and class Damage : AbilityStep this makes it very confusing when looking at the code and much harder to follow. I would rename the class to something like DamageStep for clarity.
Your field naming is also inconsistent which again makes it harder to follow what is going on (plus just looks messy).
You add an ability using direct access to the instance instead of using SerializedProperty. This will make it so it won't support prefab overrides or undo also the change may not be saved since it doesn't dirty the object.

This would be the proper way to do it.

property.arraySize++;
property.GetArrayElementAtIndex(property.arraySize - 1).managedReferenceValue = new Abilities.Steps.Damage();

[slender jetty]

I was looking for a long time for a way to do add them 😛 Might change it to that.

I know the field names are a bit messy, but I have started not cleaning up my code too much before it works - helps me avoid endless refactoring.

Apart from crashing though, it seems to work fine? I can't figure out why it crashes when I try to set the amount in my damage

[gloomy chasm]

Try commenting out damangeLines and Stats in struct Damage, see if it still crashes

[slender jetty]

Then it doesn't crash

It can also show stats

[gloomy chasm]

Comment out DamageType type in DamageLine

I am pretty sure that is it given the log you posted

[slender jetty]

Yup, it works when that one is not there

[gloomy chasm]

So, what is DamageType? Where is it defined?

[slender jetty]

Same namespace as the Damage and DamageLines

    public enum DamageType
    {
        Magic,
        Physical
    }

[slender jetty]

It's just an enum

[analog grove]

Heyo, had a couple of questions. I'm trying to create a selector that uses a popup. don't know how to send the values back to the serialized propery, I tried using a callback when OnClosed but said the property had already been disposed of.

[analog grove]

I'll add some info in case someone knows how to do this. Unity seems to do this using a reference to the GUIView and events but this is not accessible. any idea on how to do something similar?

[onyx harness]

Send an event to the parent Window

@analog grove

window.SendEvent(new Event() { commandName = "mypopup", button = 123 });

[outer ether]

Any idea why unity on macos and linux lacks the full PATH environment value of my system?

On windows you get this: C:\Python310\Scripts;C:\Python310;C:\Program Files\PlasticSCM5\server;C:\Program Files\PlasticSCM5\client;C:\Windows\system32;...
Everything defined under the windows' PATH settings are available

On macOS this is all that gets returned by
Environment.GetEnvironmentVariable("PATH")
PATH = /usr/bin:/bin:/usr/sbin:/sbin

[onyx harness]

Define "lack"

[slim vector]

so i've copied this editor script from here (https://docs.unity3d.com/ScriptReference/PrefabUtility.html) to create prefab for me automatically without needing to drag each mesh into the Project folder manually but the resulting prefab created using this tool have a different icon (blue box with grey side). i believe it is a prefab variant(?) and i was wondering if it is possible to create the prefab with the fully blue box instead?

[waxen sandal]

Looks pretty normal to me..?

[outer ether]

Things that are the default such as /usr/local/bin not available in Unity.
macOS defines its PATH var from /etc/paths

[waxen sandal]

Probably SaveAsPrefabAsset instead of SaveAsPrefabAssetAndConnect

[outer ether]

nothing user installed can be accessed via Process.Start with the Unity provided PATH

[slim vector]

tried it, still the same

[waxen sandal]

That's not the Unity provided PATH, that's how osx works

[slim vector]

a prefab and prefab variant are pretty much the same right?

[waxen sandal]

Also, you can start user installed apps but they should be available from the commandline as well, which is generally what /usr/local/bin//usr/bin is used for

[waxen sandal]

Variants inherit properties from the parent Prefab, they can also override specific properties but most will be the same as the parent

[outer ether]

ehakan@mbp ~ % cat /etc/paths
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

That's my issue, the PATH should have /usr/local/bin if it actually used the macOS defaults

[slim vector]

i see

[waxen sandal]

What does echo $path return?

[outer ether]

/usr/local/opt/openjdk@11/bin:/Users/ehakan/grpc:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/share/dotnet:~/.dotnet/tools:/Library/Apple/usr/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Applications/Wireshark.app/Contents/MacOS:/Users/ehakan/.cargo/bin

[slim vector]

how can i make it a prefab instead of a prefab variant though?

[outer ether]

I only defined the first two items in my .zshrc, the rest are "system"

[slim vector]

kinda ocd about the different icons in my prefabs folder

[outer ether]

as in it just gets embedded with every terminal instance

[waxen sandal]

My path doesn't have /usr/local/bin by default, my shell is adding it

[waxen sandal]

Try copying the gameobject (using Instantiate) before doing SaveAsPrefabAsset, not sure tbh I haven't used that api much

[slim vector]

alright will try

[outer ether]

Thanks for the heads up. I found out about /usr/libexec/path_helper, it's apparently what builds the PATH value for shells, invoked in /etc/profile. Bodged this together

Hi! how can i do a "CreateAssetMenu" that creates a class inheriting from another class of mine? (ie i've got an ActionBase class, and i want a button in assets/create/New Action to create a new action script inheriting for ActionBase by default?
The little things)

[waxen sandal]

CreateAssetMenu is just a MenuItem that creates a SO for you, so you can just create your own static method with MenuItem that makes an SO at some location

[tough stream]

oooh okok :)
Thanks!

[waxen sandal]

I'm not sure what exact source is but there's probably a bunch of examples online

e.g. this https://www.richardlord.net/blog/unity/creating-scriptableobjects-in-unity.html

It won't give the exact same functionality but it's similar

[waxen sandal]

Very interesting, thanks for letting me know!

[tough stream]

don't worry, i figured :)
Anyway, can i enter like... "Renaming" state for a selected object...? lol

[waxen sandal]

ProjectWindowUtil.CreateAsset(asset, assetPath);

I should've etold you about this one before probably

[tough stream]

this seem pretty convenient

thanks!

[tough stream]

what if i want to load all the scriptables inside a folder (that i've got the path too)?

AssetDatabase.LoadMainAssetAtPath doesn't seem to be working

[gloomy chasm]

Working to do what?

[tough stream]

to load all the scriptables inside a folder (that i've got the path to)

[gloomy chasm]

It only loads one asset, and it needs to be the full asset path

Assets can have sub-assets, that is what it refers to when it says "MainAsset"

[tough stream]

yeah, like sprites right

so what if i want to load all the scriptables inside a folder (that i've got the path to)?

[gloomy chasm]

You use Directory.EnumerateFiles and load each one at a time

note that all System.IO methods take a full path and not one relative to the project. Likewise, all of Unity's AssetDatabase methods require a path relative to the project

[tough stream]

bruh
But i can get the unity path to asset with someething right? Like assetdatabase.ProjectPath?

[onyx harness]

what?

[gloomy chasm]

What what?

[gloomy chasm]

You can use Application.dataPath to get the system path to the Assets folder

[onyx harness]

Methods in System.IO does not require a full path, they can take any path

if I ask for Directory.GetFiles('.') it works

[gloomy chasm]

But you can't do like Directory.GetFiles("MyProject/Assets"), right?

[onyx harness]

You can't, because the current Directory is set on the projecct path, so it would accept "Assets", "Library", "Temp", etc.

You are making me doubt, but I am 99% sure it is

[gloomy chasm]

Well now you are making me doubt too because I was like 98% sure...

[onyx harness]

The thing is, System.IO is .NET, not Unity

And now that I am think about it, I'm 100% sure

it takes whatever you give it

be it absolute, relative, network

[slim vector]

hmmm so any solution?

[gloomy chasm]

Was it a prefab already?

[slim vector]

i assume it is? it's a mesh

[gloomy chasm]

Then yes it will be a prefab variant. That is expected

That way if the mesh changes it will update as well

[slim vector]

how can i make it an original prefab though?

hmmm

when i drag the mesh into the folder, i get an option to either make it an orginal prefab or a prefab variant

how does unity make it into an original prefab from there?

instead of a variant

[gloomy chasm]

I don't do much with the prefab API, but my guess would be to use UnpackPrefabInstance first
https://docs.unity3d.com/ScriptReference/PrefabUtility.UnpackPrefabInstance.html

I should say that unless you have a specific reason for doing this, the recommendation is to make it a variant of the model instead

[slim vector]

alright

[slim vector]

one more thing, is it a must for the editor script to inherit from Editor? i remember watching some videos regarding creating custom tools and some of their script(s) doesn't inherit from Editor at all

[gloomy chasm]

Nope, not at all. You only inherit from Editor if you want to create a custom inspector (change the way a component or scriptable object is drawn in the inspector)

[slim vector]

i see i see

cause currently i am inheriting from Editor but the script itself isn't for a custom inspector, rather it is for a menu item instead

[gloomy chasm]

Yep, no need for it then

[slim vector]

what if i'm inheriting from Editor just so i can use DestroyImmediate?

right now once i create the prefab(s), i want to delete the selected gameobject(s) from the scene

[gloomy chasm]

No need, DestoryImmediate is a static method

Object.DestoryImmediate(yourObjectInstance);

[slim vector]

ahhhhhhh right

thanks a lot

//I can't save my scene particle effects into the project if I do this. It unlinks the Particle->Renderer->Material to null
//How would I be able to save my scene particle effect into my project properly if I want to change the material on runtime?

I think I need to write an editor extension to make new materials maybe on the fly?

A better question is: If I instantiated something in UNITY play, how do I save the result as an asset into my Project Assets?

[gloomy chasm]

iirc it should be the same as during edit mode. Just AssetDatabase.CreateAsset(..)

However I could be wrong on this one, I don't remember for sure

[mossy wren]

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

yup

https://docs.unity3d.com/ScriptReference/PrefabUtility.html for game onbjects

AssetDatabase.CreateAsset for non game objects

this is awezome!

[analog grove]

heyo, just a quick question, is there a better way to get the window in which the propertydrawer is being drawn on, other than getting the focused window?

[gloomy chasm]

There is if you want to use some reflection. UnityEditor.GUIView has a static currentView property.

[analog grove]

I know about that one but it's internal, guessing that's why i need Reflection. Is it okey to use for packages??

[gloomy chasm]

...what?

[analog grove]

lol sorry, wrong copy paste xD edited

[gloomy chasm]

It is 'okay'. Just be aware that in a future version it might change because it is internal.
With that said, that one should be very save unless they do a massive rewrite of the internal window system

[analog grove]

oh okey, yeah i can just have a failsafe and it should be okey. Guess I'll learn some reflection then

[onyx harness]

Go learn go learn little padawan

[rocky vapor]

Thanks ill try

[tough stream]

hi! how do i know if an .asset exists at some path?

do i need to do like a try catch maybe?

cuz i just tried this:

ScriptableCharacterList CharList = ScriptableObject.CreateInstance<ScriptableCharacterList>();
            try {
                list = AssetDatabase.LoadAssetAtPath<ScriptableCharacterList>("Assets/SCOLAssets/CharacterScriptables/CharacterList.asset");
            } catch {
                AssetDatabase.CreateAsset(CharList,"Assets/SCOLAssets/CharacterScriptables/CharacterList.asset");
                list = AssetDatabase.LoadAssetAtPath<ScriptableCharacterList>("Assets/SCOLAssets/CharacterScriptables/CharacterList.asset");
            }```
And somehow it's not creating anything
(my class doing this is editor only and static)

(well, the class itself isn't static, but all the other things in it are (including this "list" variable))

[tough stream]

Help me i feel like i'm doing totally illegal things

ScriptableCharacterList CharList = ScriptableObject.CreateInstance<ScriptableCharacterList>();
            try {
//If the list already exists, we just say it's THE list
                ScriptableCharacterList.Instance = AssetDatabase.LoadAssetAtPath<ScriptableCharacterList>("Assets/SCOLAssets/CharacterList.asset");
            } catch {
//If it doesn't, create it... And tell it's THE list
                AssetDatabase.CreateAsset(CharList,"Assets/SCOLAssets/CharacterList.asset");
                ScriptableCharacterList.Instance = AssetDatabase.LoadAssetAtPath<ScriptableCharacterList>("Assets/SCOLAssets/CharacterList.asset");
            }```

How can access the "Validate References" field of a .dll through an editor script? I get the PluginImporter for the asset but I'm not sure on how to set the "validate references" field?

oh, yeah
when i createAsset(), right?

Hey guys! I'm creating an editor tool that will create a bunch of assets using AssetDatabase.CreateAsset and also prefabs. Problem is that operation is taking way too long... I've tried using AssetDatabase.DisallowAutoRefresh(); but to no avail... Is there anything else I can do?

AssetDatabase.CreateAsset(material, Path.Combine(meshPath, $"{filter.gameObject.name}.mat"));
                 AssetDatabase.CreateAsset(filter.mesh, Path.Combine(meshPath, $"{filter.gameObject.name}.asset"));
                 var partPath = AssetDatabase.GenerateUniqueAssetPath(Path.Combine(meshPath, $"{filter.gameObject.name}.prefab"));
                 PrefabUtility.SaveAsPrefabAssetAndConnect(filter.gameObject, partPath, InteractionMode.UserAction);

[worthy mist]

Found a solution... AssetDatabase.StartAssetEditing(); and AssetDatabase.StopAssetEditing(); will do the trick

[sharp rune]

Hey can someone help me? I've never written anything for the editor, so I'm a little lost on where to begin.
I'm trying to write some code that will let me change the colors for: selected polygon colliders, awake polygon colliders, selected box colliders, awake box colliders

I want these 4 things to be different colors so I can quickly tell what I have selected, and what the other colliders in my scene window are without clicking through the hierarchy

I can enable always show colliders in the project settings, but the problem with that is, everything is the same color, even colliders I have selected, so I cant tell what it is I'm editing

I'm currently trying to create an instance of a custom editor script via CreateEditor(object, type). However, this function only seems to create the base "Editor" class, and trying to cast it to my custom editor type fails. I've double checked all the necessary attributes and inheritance setup, but have had no luck. Has anyone else encountered this problem before?

[whole steppe]

is it possible to add custom game objects context menu item?

    [MenuItem("GameObject/HelloWorld", false, 10)]

    }

Guys I need your help. I have an assignment to get a job.
I need to setup a connection with this thing:
https://github.com/PokemonTCG/pokemon-tcg-sdk-csharp
an just make a game with it.

My Visual studio 2019 whenever i try to install the package:

Could not install package 'PokemonTcgSdk 1.1.1'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.7.1', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.

So I downloaded the 1.1.0 version

My new error is that now that I have the new classes etc when I try to test em in Unity I get this error: (Only in Unity not in the VS console)

Assets/GameManager.cs(4,7): error CS0246: The type or namespace name 'PokemonTcgSdk' could not be found (are you missing a using directive or an assembly reference?)

I suspect that it is the SDK version but I cant locate where to select the one I use plus I think my VS is buggy all along.

P.s I use Mac

[gilded onyx]

Help please

[viscid gulch]

I really don't know how everything works on mac, i'm using endeavourOs and I had some similar problems when installing from different repos, f.e. vsCode installed from flathub wouldn't be able to locate .Net. from aur. This is probably unrelated, just trying to help.

hi people, I've been trying to figure out how this is done but I'm not really finding a way. I basically want to make a search bar. The code works, but I would like to make it 1. prettier and 2. a bit more functional by having a search icon and when text is present have a cross to delete, sort of like the hierarchy tab. Does anyone know how to add these icons to the text field?

Hi, is there a way to step thru the code the unity editor executes at certain times? I'm specifically try to go through the asset (model/fbx specifically) import process to get a better idea how to customize I. I find the unity docs concerning it to be pretty vague on a lot of things, at least to a unity young'en like myself

[vague herald]

so... I have very little property drawer experience, but I was working on a SmartEnum implementation for Unity with a property. Recently was playing with it and realized that it didn't work in the case that fieldinfo was a List.

        {
            //Begin Property
            EditorGUI.BeginProperty(position, label, property);

            //Get Current Value
            var smartEnum = (SmartEnum)fieldInfo.GetValue(property.serializedObject.targetObject);

            //Get All Other Possible Values
            var enumList = SmartEnum.GetValues(smartEnum);

            //Get Current Index
            var i = enumList.IndexOf(enumList.FirstOrDefault(x => x.Equals(smartEnum)));
            i = (i < 0) ? 0 : i;

            //Make Possible Values into List
            string[] options = enumList.Select(x => x.ToString()).ToArray();

            //Do a Popup and Get Selection
            var j = EditorGUI.Popup(position, property.displayName, i, options);

            //Set Value to Current Selection
            fieldInfo.SetValue(property.serializedObject.targetObject, enumList[j]);

            //End Property
            EditorGUI.EndProperty();
        }

Was wondering if anyone could give me some ideas or help on making this Array or List Compatible?

[waxen sandal]

What exactly is not working?

[vague herald]

It is not Array Compatible, when I make a List<SmartEnum> it breaks

[waxen sandal]

🤦‍♂️

What breaks

How does it break

any error?

[vague herald]

The Specified Cast at

            var smartEnum = (SmartEnum)fieldInfo.GetValue(property.serializedObject.targetObject);``` 
is invalid

it is a List<SmartEnum>

That is the problem. I want it to work within Lists.

(or other serializable array types)

oh shit, I think I figured it out

was [CustomPropertyDrawer(typeof(SmartEnum), true)], that true shouldn't be there
Wait nvm, that just breaks the styling

[vagrant zinc]

Hi,
i have a script that introduces own fields in the inspector, by using [SerializeField] private Material glowMaterial;

The inspector then takes "glowMaterial" word and forms the field name of it, resulting in "Glow Material".

How could i set the field name in the inspector to a different name, i.e. "Material" only?

[gloomy chasm]

This will break alot. If you have a SmartEnum in another class that is a field of a UnityEngine.Object, or as you see is in a list

[vague herald]

I am not sure what the alternative ought to be, that is the issue and getting information on this stuff is archaic

[gloomy chasm]

You're 'not supposed to'. I have an implementation on github of how to get the value. You can just grab and use it if you want
https://github.com/MechWarrior99/Bewildered-Core/blob/main/Editor/Extentions/SerializedPropertyValueExtensions.cs

Basically you have to split the path of the property and get the value of the field of each property in the path

[vague herald]

nice, going to add it as a package dependency, as it is lightweight enough

btw, do you support https://github.com/mob-sakai/UpmGitExtension#usage ?

[gloomy chasm]

I will say, idk what the structure of SmartEnum is, but I don't think you need to do it the way you are

[vague herald]

A SmartEnum is a pattern for Enums, wherein it looks like this:

{
    public static readonly TestEnum One = new TestEnum(nameof(One), 1);
    public static readonly TestEnum Two = new TestEnum(nameof(Two), 2);
    public static readonly TestEnum Three = new TestEnum(nameof(Three), 3);

    private TestEnum(string name, int value) : base(name, value)
    {
    }
}```

It allows for certain benefits. Such as Injectability, attaching values, and preventing extension

[gloomy chasm]

Not explicitly, from reading it, it seems like it should just work?

[vague herald]

until unity enforces its own standard for git packages, this seems to be one of the most popular versions to do versioning...

Ugh, Unity devs, if you can hear me, please just integrate whatever this guy did into your package system by default.

[gloomy chasm]

I could be wrong, but I don't think this will work

The reason being that Unity serializes everything as a value and not a reference.

So doing myTestEnumField == TestEnum.One would be false

I think

[vague herald]

I overwrite the == function

SmartEnum is direvative of IEquatable<SmartEnum>

I just check if value is equal

[gloomy chasm]

Oh, got it

It would be best if you could recreate the assignment logic using SerializedProperty as assigning values using FieldInfo has a number of drawbacks.
Doesn't dirty the object(may not save unless something else changes), doesn't support undo, doesn't support prefab overrides.

[gloomy chasm]

You can use the [InspectorName("Material")] attribute.
Edit: My bad it seems this is only for enums. Sorry

[vague herald]

Unity is Unity, there is a ton of stuff that I wish it had built in so I wouldn't have to hack to get around it.

And of course, there is the whole problem of developing a solution and then someone out there rediscovers your problem and can't solve it, because you aren't at the top of search results

anyway, none of this is relevant to this channel so I am going to stop

thx for help

[vagrant zinc]

Thank you for getting back to my question! I tried using this but maybe i am using it wrong? I did it like this:

[SerializeField] [InspectorName("Material")] private Material glowtMaterial;

[gloomy chasm]

Looks like there isn't a way. Either custom editor, or just rename the field.

[vagrant zinc]

After googling more on your answer, i found this: https://docs.unity3d.com/ScriptReference/InspectorNameAttribute.html
This looks to be the solution, but i do not understand the implementation

[gloomy chasm]

It turns out it only works for enums, not fields.

[vagrant zinc]

ohh ok 😕

Ok atleast i now know there is no way to achieve this, i was stuck on this for an hour about and finally can move on. But i think i will place this as feature request at unity's

@gloomy chasm Thank you for your help ✌️

I'm having issues with handling selective click events in a property drawer

I'm making a PropertyDrawer that is an object field, but it has extra height for drawing other fields below.
I want to consume the event selectively if I click on the area that is not the object field

as you see in the GIF, the object field's context menu appears when clicking in any area of the entire drawer (that doesn't have another field)

so I basically want to consume the event and not show the context menu when I right click on the area highlighted in red
