[carmine bone]

tbh as a technical animator I can't think of a reason to switch BT anims during runtime

But Editor yes

If anyone know show to assign an animclip to the motion fields in a blendtree without resetting things like parameters and thresholds etc. pls ping me 🙏

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

maybe in a recursive way but im not that advanced, pls let me know

(figured it out, can just reconstruct the blendtree)

[wary plover]

Does anyone know of a way to keep your test Assets in com.mypackage/Tests/ from importing into everyone's projects? The test assemblies get excluded (great!) but the assets in that folder still get imported.. which causes import errors because they depend on the test assemblies. -.-

[tardy pecan]

Is there a way to add new entries to the context menu of another component? For example if I wanted to add something to the Rigidbody context menu

[visual stag]

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

[tardy pecan]

Oh thanks! Missed the CONTEXT/Rigidbody/Double Mass thing!

[shell beacon]

Hello guys. I'm working on an editor extension to upload to the Unity's Asset Store and wondered if I can use Asset Labels on some\all of the files
https://docs.unity3d.com/Manual/Searching.html#:~:text=in the results.-,asset labels,-A label is

[gloomy chasm]

What do you mean?

[waxen sandal]

Probably different plugins but this channel is not for getting your IDE to work

Try #💻┃unity-talk or something

[wanton arrow]

OH

I totally misunderstood this

sorry lol

[indigo condor]

hi everyone... Does anyone knows how could i solve this little bug that makes the add data boxhelp to get smaller when it doesn't fit the window?

https://paste.ofcode.org/n2K64HtXz3iTNHETvNKiF5

[gloomy chasm]

I know this isn't helpful. But have you considered using UIToolkit? It would work so much better and easier for the type of UI you are doing.

[indigo condor]

a few more people have said me that too... but appart from the UI, the asset logic is made for IMGUI (cause when i started with my asset i didn't knew about ui toolkit) so, changing all it would take me a few more time... and honestly i really like the visual part of it xD.

[gloomy chasm]

More time than you have spent trying to get this tiny section of the UI to work? 😉

And logic is super easy to port over most of the time. (Having ported complex UIs from IMGUI to UIToolkit my self)

[indigo condor]

Hmm, good point of view

[gloomy chasm]

For reference, to create the layout how you want in UIToolkit, it is 5 elements, and setting ~3 properties. flexDirection = Row, width = 25% flexGrow = 1

[indigo condor]

and @gloomy chasm wich elements do you think i need for setting up the ui im currently doing?

[gloomy chasm]

If we exclude all the controls and just focus on the layout. You just need VisualElements to act as containers

[indigo condor]

like menu and styles?

[gloomy chasm]

I would read a intro to UIToolkit

Getting started docs: https://docs.unity3d.com/Manual/UIE-simple-ui-toolkit-workflow.html
Unity Learn: https://learn.unity.com/tutorial/ui-toolkit-first-steps

[indigo condor]

do you know how could i change the margin color?

to add that kinda darker space

[gloomy chasm]

First thing, in the "library" panel, click on the 3 dots icon and select the "Editor extension" option. Then go top right of the "Viewport" panel and switch from the "runtime" theme to the active editor theme.

[indigo condor]

ohh, muchh better

[shell beacon]

Hi man how are you? 🙂
I Just wondered if it's a good practice to use labels for shipped assets.

[indigo condor]

@gloomy chasm do you know why i can't see the window? https://paste.ofcode.org/x4r3PCbYbGNDnKzdNex3sf

it's probably my code...

i've found it on the web

[visual stag]

Use CreateGUI, don't use OnEnable

[indigo condor]

it still being empty

[visual stag]

Check if there's anything under the root element at all using the UI Toolkit Debugger

(right click on the editor tab to find it)

and check whether the function is called at all; double-checking it's all running

I can't see anything immediately wrong

[indigo condor]

it's like it exists

but it's kinda invisible

[visual stag]

Concerning error in the console

You should really not be sending the root visual element to the back

Don't touch that element except to add to it

[violet solstice]

Is there a way to show this window and get the result? It's the one that normally shows up when you click the icon next to texture2d assets in the default inspector. Guessing not normally and I'll have to find an alternate solution... :\

Tried searchin here, on google, and askin chatgpt, but no luck.

[real spindle]

Also interested, please ping me if you get an answer

[indigo condor]

done!

[indigo condor]

how could i move the splitter under the buttons?

i used an slider cause i didnt find any kinda splitter

xd

[gloomy chasm]

@violet solstice @real spindle If you use IMGUI you can use commands Event.current.command, but that is a pain and doesn't work for UIToolkit. So I use a internal method that has a callback This is some code I ripped out of my utility class (AccessUtility is just a wrapper around reflection) https://gdl.space/ifinoqazod.cs

[gloomy chasm]

What do you mean how? Like visually or or in the hierarchy, or...?
Also, if you want a splitter like how you can drag it to resize the left and right sides like the in the project browser. Then in the UXML you can use a TwoPlaneSplitView. It just isn't in the UIBuilder for some reason.
Hoever, if you just need it to be a visual line. No reason to use a slider. Just use a normal VisualElement, set its height to 2 or whatever, and have it flexGrow.

[vague spear]

Is it possible to call a method exactly once when changing a toggle in custom editor? Tried using EditorGUI.EndChangeCheck() but is called every frame. Using propertyfield for a toggle.

...
EditorGUILayout.PropertyField(boolVar, new GUIContent("Is bool"));

[gloomy chasm]

Can you show what you mean as change check should work

[vague spear]

Here is my current code:

EditorGUILayout.PropertyField(originalBlockMode, new GUIContent("Block Mode? (Initial)"));

// Initialize Mode
if (EditorGUI.EndChangeCheck())
{
    GatorBlock gator = (GatorBlock)target;
    gator.InitializeMode(originalBlockMode.boolValue);
}

Am I missing something?

[gloomy chasm]

No that looks correct assuming you have a BeginChangeCheck above the PropertyField. If you debug.log it, does it get called multiple times? (I am explicitly asking for a debug.log so I know that something somewhere else isn't going funky)

[indigo condor]

it's just the line... how could i change it's color...? i can't change it on bg

[vague spear]

whoops missed the BeginChangeCheck

[real spindle]

Thanks, but what do you mean with Event.current.command? Isnt that just the command/windows key?

(I'm still using IMGUI but plan on migrating to UITK)

Oh you probably mean commandName?

[gloomy chasm]

Uhh, yeah, it is forever since I did it that way.
https://docs.unity3d.com/ScriptReference/EditorGUIUtility.ShowObjectPicker.html

https://discussions.unity.com/t/how-do-i-use-editorguiutility-showobjectpicker-c/83996/2

[gloomy chasm]

You change the color in the Background section on the right of the UIBuilder window.

[indigo condor]

not working

[gloomy chasm]

Did you set the hight like I said?

[indigo condor]

yep

[gloomy chasm]

Also, I really recommend you reading up on it more, it will make it far easier for you to use quickly

[gloomy chasm]

That is the max height

[indigo condor]

and what do you mean...? sorry for being that hard 😅

[gloomy chasm]

Ahh, the Color field in Background, the alpha is 0!

[indigo condor]

oh my bad hehe

thanks!

[indigo condor]

and one last thing @gloomy chasm... is there any way to change the margin color?

or i need to add a visual element manually

[gloomy chasm]

No, that is not how margin works. If you want a colored border, then use the border properties. And if you want just want space between the edge of the background and the contents, then use padding. Margin is just adding space between the bounds of the element and all other elements around it.

[indigo condor]

right

[uneven shore]

Hi all! I've been struggling to code an inspector list field in a particular way and found this post from a couple of weeks ago where someone else is looking for the same thing:
https://discussions.unity.com/t/modify-behavior-of-editors-draganddrop-on-list-t/330337

There haven't been any answers yet so I thought I'd share in case anybody can help 😀

[gloomy chasm]

It's probably cause the List is using the event if I had to guess. Meaning you would need to do your Drag and Drop logic before drawing the list.

[uneven shore]

But how can I know if dragging on top of the list before drawing the list? 😅 Any example of this would be much appreciated!

[gloomy chasm]

Yeah it isn't nice, there is no nice way to do it haha. You could draw it specifically, then after it in Repaint use GUILayoutUtility.GetLastRect() possibly get and store the rect in a field and use that to know.

Might have to surround the list with a EditorGUILayout.BeginVertical as that returns a rect

GUILayoutUtility.GetLastRect() might return the last element in the list. I don't remember off the top of my head, but I think that is the case now that I think of it.

I personally would use UIToolkit for it as it is much easier to do in that.

[uneven shore]

Oo so if I draw the property with UI Toolkit instead then it'd be easy to modify the drag-to-list-header behaviour?

[visual stag]

100%

[uneven shore]

Oo then I am definitely interested! 😀 Although I've not done inspector drawers with UI Toolkit before. Any hello-world pointers, particularly around using Unity's existing list display?

[visual stag]

The only real problem you'll face is that UITK is not immediate, so ProperyField is built after a Bind callback, which is then delayed. So creating the list via PropertyField you will probably need to register a GeometryChangedEvent or similar and then query for the right element to register your drag callback to; and you'll need to unregister the GeometryChangedEvent to make sure that doesn't occur constantly when you're done.

UITK is generally not simpler; it's just that most things are possible, when they would just be impossible in IMGUI

Though, there's a lot less unreadable IMGUI bullshit, just replacing it with and a lot more events and queries

[uneven shore]

Yeah cool. I actually use UITK for the game's main UI lol, I've just never used it for inspector scripting, so I need a primer on how to hook things up in that context. But thanks for mentioning that GeometryChangedEvent! Definitely would not have known to look for that

[visual stag]

Very odd to use it in the context where it's not yet recommended, but to have avoided in the one where it's been recommended for years 😛

[uneven shore]

Hmm @visual stag I've managed to use a visual element as a property drawer, however it's being used inside the list. e.g. I'm not controlling how the list itself is displayed, but how each individual element inside the list is 🤔 This means I can't modify the list header's drag behaviour?

[visual stag]

What version of Unity are you using?

[uneven shore]

2022.3.19f1

[visual stag]

You can't target collections in that version of Unity; so you'll have to make an editor and query from there

[uneven shore]

Ooft

I see, thanks!

[vague spear]

Hello, got an issue where hitting play mode resets a serialized variable. What I'm doing is that I have an editor property field for changing varX and also have another editor script that has a button that validates everything and so happens to be that varX is changed as well. All good in editor but when hitting play varX resets back when it is changed through the other editor script.

it is though 🤔

[boreal aurora]

oh my bad

[visual stag]

You're going to have to send your code

[rustic meadow]

Hey! I'm doing custom editor and for some reason I can not drag and drop TextMeshProUGUI value.

public TextMeshProUGUI titleText; <- in monobehaviour class
slider.titleText = (TextMeshProUGUI)EditorGUILayout.ObjectField("TMPro title", slider.titleText, typeof(TextMeshProUGUI), false); <- editor class

I have used this same way to add custom audio managers and stuff, but why it does not work for TextMeshProUGUI ?

[boreal aurora]

Change it to TMP_Text

[visual stag]

Is there a reason you have specified false to scene objects?

[rustic meadow]

I'm so stupid... thank you!

[indigo condor]

which is the difference between a visual element or a groupbox?

anyone knows how to apply shader to the editor camera? I wrote a raymarching shader, but I can only visualize it by applying a material with this shader to the mesh, and it is really tedious

[urban atlas]

Hello . I am attempting to build an app with Geospatial from AR core. On a Mac. I’m getting an error message regarding the installation of “CocoaPods” ? Has anyone else encountered this? Any suggestions on resolving it ? Thanks

[terse hazel]

I'm unsure on how to track the value of a SerializedProperty with UI Toolkit/UIElements, what should I use for that?

I want to track the target's positionUnitsBackingField and execute some code whenever that changes, but the code I wanna execute should know the previous value as well.
I know you can use RegisterValueChangeCallback() for things like IntegerField but AFAIK, that isn't possible for a general PropertyField?

RegisterValueChangeCallback can only register those with a SerializedPropertyChangeEvent argument, but those don't store the previous value from what I can tell.

var row = ux.AddChild(InspectorUtility.PropertyRow(serializedObject.FindProperty(() => Target.CameraPosition), out _));

SerializedProperty positionUnitsProp  = serializedObject.FindProperty(() => Target.positionUnitsBackingField);
PropertyField      positionUnitsField = new (positionUnitsProp, label: "") { style = { flexGrow = 2, flexBasis = 0 } };
row.Contents.Add(positionUnitsField);

//...

//ERROR: Expected a method with 'void PositionUnitsChanged(SerializedPropertyChangeEvent)' signature
positionUnitsField.RegisterValueChangeCallback(callback: PositionUnitsChanged);
void PositionUnitsChanged(ChangeEvent<PathIndexUnit> evt)
{
    Debug.Log("oldUnits: " + evt.previousValue + " newUnits: " + evt.newValue);
    
    Target.UpdateDistanceForPositionUnits(evt.previousValue, evt.newValue);
}

I thought I'd be clever and do this, which doesn't give me any errors/warnings, but that doesn't call the PositionUnitsChanged at all

// Store the initial value
PathIndexUnit previousUnits = Target.positionUnitsBackingField;

// Handle change event manually
positionUnitsField.RegisterCallback<ChangeEvent<PathIndexUnit>>(PositionUnitsChanged);
void PositionUnitsChanged(ChangeEvent<PathIndexUnit> evt)
{
    PathIndexUnit newUnits = evt.newValue;
    Debug.Log("oldUnits: " + previousUnits + " newUnits: " + newUnits);
    
    Target.UpdateDistanceForPositionUnits(previousUnits, newUnits);
    // Update previous value for the next change
    previousUnits = newUnits;
}

[terse hazel]

This works.
Still unfortunate something like the prior doesn't work, but if it works it works.

Are there any alternative ways to do it, what's the proper way to do it here?

PathIndexUnit previousUnits = Target.positionUnitsBackingField;
ux.TrackPropertyValue(positionUnitsProp, TrackPositionUnits);
void TrackPositionUnits(SerializedProperty p)
{
    PathIndexUnit newUnits = (PathIndexUnit) p.enumValueIndex;
    Debug.Log("oldUnits: " + previousUnits + " newUnits: " + newUnits);
    
    Target.UpdateDistanceForPositionUnits(previousUnits, newUnits);
    // Update previous value for the next change
    previousUnits = newUnits;
}

[alpine bolt]

I'm having an issue where the first item of a List built with PropertyField went on a walk.

[alpine bolt]

You can get the IntegerField and whatever field you draw with PropertyField. The thing is, when the PropertyField gets attached to the panel (AttachToPanelEvent) it is just an empty shell. So, the trick is to wait for the GeometryChangedEvent to Q<> for the field you are looking for.

[safe sorrel]

Can I set a custom icon for a specific scriptable object?

I have a bunch of SOs that store variations of a single icon

they're all Sprites

I'd like to be able to see one of the sprites, rather than the generic scriptable object icon

EditorGUIUtility.SetIconForObject got me excited, but that's for game objects and mono scripts

I know how to set a custom icon for an entire kind of scriptable object, but that's not sufficient here.

I see that I can ask for the path to the .meta file for an asset. Perhaps I'm meant to just edit it myself?

[indigo condor]

i have those pages on my window... but my question is how i should do them...

Is it good to create each page on a different visual element?

[alpine bolt]

I sorta did it half way. It's not fun, I can tell you that

using UnityEditor;
using UnityEngine;

namespace Tauntastic.Tests
{
    [InitializeOnLoad]
    public static class FakeAssetSetIcon
    {
        static FakeAssetSetIcon()
        {
            EditorApplication.projectWindowItemOnGUI += OnProjectWindowItemOnGui;
        }

        private static void OnProjectWindowItemOnGui(string guid, Rect selectionrect)
        {
            var asset = AssetDatabase.LoadAssetAtPath<FakeAsset>(AssetDatabase.GUIDToAssetPath(guid));
            
            if (asset != null && asset.Icon != null)
            {
                GUI.DrawTexture(selectionrect, asset.Icon);
            }
        }
    }
    
    [CreateAssetMenu(menuName = "Tauntastic/FakeAsset", fileName = "FakeAsset")]
    public class FakeAsset : ScriptableObject
    {
        public Texture2D Icon;
    }
}

[safe sorrel]

ah, I see: you provide a static method that draws the texture

[alpine bolt]

You'll have to do a bunch of not fun things to make it look seamless.

[gloomy chasm]

Yeah... now if only I can remember how... uhh... maybe it was using the one of the Preview methods in the custom Editor class... or something to do with importers... 🤔

Its been a long time

[safe sorrel]

I'll settle for generic icons, then 😅

I wound up making the issue a bit moot anyway

I switched from referencing the icon sets manually to just putting control paths directly on the icon sets

[gloomy chasm]

Ahh No i think I was right, it is the RenderStaticPreview in Editor

[safe sorrel]

and then I just use an editor script to cram all of these into a list to be loaded when the game starts

so, no need to be able to eyeball what's in an icon set

i used the editor scripting to destroy the editor scripting

[gloomy chasm]

Hahaha

[safe sorrel]

I've been using more and more editor scripts as of late. It's really nice.

I was about to manually drag and drop hundreds of sprites into scriptable objects

[gloomy chasm]

Yeah, editor script is great!! 😄

[alpine bolt]

Oh, nice

[dapper coral]

is there a way to programmatically close and open a window? specifically a UI Toolkit window

I have it under [MenuItem("Window/UI Toolkit/Logsets")] which works, but I'd like to be able to have a "reopen" button in the window that'll close it and reopen it

[gloomy chasm]

EditorWindow.GetWindow(type)

EditorWindow.HasOpenInstance(type)

You can use the first to open the window, and use the second to see if one is already open or however you want to do it.

[dapper coral]

ohh nice, thanks!

[waxen sandal]

There's also ExecuteMenuItem

(It doesn't do the same thing but lets you open any window even if you don't have access to the type)

[peak bloom]

how should I go about making a floating overlay like this one ?

that floating Navigation one I mean

so it would behave the same too, only moveable in the scene view

[waxen sandal]

IT's uhh something

https://docs.unity3d.com/Manual/overlays-custom.html

These ones I think

@peak bloom

(Overlays is such a bad name)

[peak bloom]

agreed, sounds like food to me 😂

thanks! 👍

yeah I think that's what I'm looking for

[reef hornet]

Hello there
does anyone know a way to offer a list of subclasses based on a baseclass as objects to add to a list?
consider this setup

class BaseClass {
  public int baseValue = 0;
}

class ChildClassA : BaseClass {
  public int childAValue = 1;
}

class ChildClassB : BaseClass {
  public int childBValue = 1;
}

and this script

class MyScript : MonoBehaviour {
  
[SerializedField]
private BaseClass[] baseObjects;
}

how can I allow a user to chose between the classes inheriting from BaseClasss to add to the list?

[waxen sandal]

You need to use SerializeReference and make your own property drawer that looks up the derived classes and adds them to a dropdown

[reef hornet]

can you elaborate?

[waxen sandal]

On which bit

[reef hornet]

looks up the derived classes and adds them to a dropdown
that one

[waxen sandal]

Ah

You can use https://docs.unity3d.com/ScriptReference/TypeCache.GetTypesDerivedFrom.html to find the derived classes

Then, in your custom property drawer, draw a dropdown, depending on what the user selects, create an instance and assign it to your property

There might also be open source property drawers that do what you want but I'm not aware of any

[reef hornet]

I'll check that out, thanks ^^

[peak bloom]

what api should I use to make a timeline like this ?

Googled it, there were several apis that do that not sure which one should I use 😅

[waxen sandal]

There's apis that do that?

[surreal delta]

from my knowledge the timeline is made in UI builder

[reef hornet]

am I assuming correctly that I wouldn't be able to assign the subclass to the baseclass property with the drawer on the baseclass type?

like, I'd have to create a wrapper with the drawer to assign the property

or can the drawer object replace itself?

[peak bloom]

there's I guess, not sure if they're accessible for public use tho. it's in their official docs too

[waxen sandal]

The type of the field determines the drawer not the type of the value

[peak bloom]

thus I asked here 🥹

[waxen sandal]

afaik it's all custom and thus there's no api

[peak bloom]

how about this one? https://docs.unity3d.com/Packages/com.unity.timeline@1.8/manual/samp-custom-samples.html

[waxen sandal]

Oh

Isn't that to extend Timeline and not to make your own timeline like editor?

Or am I misunderstanding what you're looking for?

[peak bloom]

no you're right, but isn't that package customizable?

I assume it is

[waxen sandal]

I guess if you make your own custom tracks then you can use it in a different way than they intended?

[peak bloom]

yeah

[waxen sandal]

But you're still locked into timeline

[peak bloom]

lemme give it a shot 1st and see 🤔

[waxen sandal]

If whatever you're doing fits into the timeline system then yeah that works

If you just want a similar UI for completely irrelevant data then no

[peak bloom]

based on this screenshot alone, I don't think it can do custom data

But I might be wrong here, lemme try it first

I might be barking the wrong tree here, so uh 😂

[reef hornet]

can I assign a new object to a serializedproperty?

Effectively I have an array of objects with BaseClass and trying to reassign the value of each array position with a subtype of BaseClass

[waxen sandal]

If it's a serialized reference you can set a new object to the serializedproperty yeah

https://docs.unity3d.com/ScriptReference/SerializedProperty-managedReferenceValue.html

[reef hornet]

but that only works with the exact same type of object right?

[waxen sandal]

With serialize reference you can also serialize derived types

Not just the base types

[reef hornet]

it worked ^^, awesome, thanks

[errant shale]

- I have in mind a custom editor utility for grid editing with in-scene gui. Docs suggest to use the handles api, and my questions are:

1. Is it possible to define custom handles, or am i limited to predefined handles?
2. If yes, what functionality can be given to custom handles? I'm interested in drag handling and cursor changing on hover and drag. Is it possible?

- Also, is it possible to integrate a custom selection logic? What i'm looking for is ability to make my edited object selectable without adding any redundant components just for this, like colliders or renderers, but purely through code

[waxen sandal]

Selection works through the Selection api

You can construct handles from separate components and change them how you see fit

And yeah you can do drag handling and cursor changing just fine

https://discussions.unity.com/t/how-do-you-make-a-custom-handle-respond-to-the-mouse/71824/3

[errant shale]

- I see that i can set selection object(s) manually, but that'd skip the entire default selection flow, right? That'd mean that my object will be selected ignoring anything else the moment it gets in the cursor's way

- Speaking of which, i see some Event variables scattered all over around the api. Is it similar to canvas ui events that can be consumed, preventing any further execution?

[waxen sandal]

It's specifically this https://docs.unity3d.com/ScriptReference/Event.html

Not sure what your custom selection needs are, does your thing exist as a GameObject at all?

[errant shale]

- Yes, it does. It simply does not contain anything but a custom script (and a transform, obviously)

[waxen sandal]

https://docs.unity3d.com/ScriptReference/DrawGizmo.html can make the gizmos you draw selectable

So you probably have to draw some gizmo to make it selectable

Then use handles in OnSceneView for your custom input things

[errant shale]

- Am i right to assume that on top of that gizmo i'll have to draw handles for actual controls? Won't they conflict with each other, or am i supposed to switch between the two when the object gets de/selected?

[waxen sandal]

Not 100% sure but gizmos are usually not interactable (except for selection purposes) iirc

[errant shale]

- Good. So learning gizmos, handles, imgui and specifically events should be enough to accomplish what i want?

[waxen sandal]

Probably

[errant shale]

- Mkay. Thank you

[surreal flume]

I have an SVG asset I am using with UITK ("UI Toolkit Vector Image" asset type). I want to access the SVG path during runtime but I think that information is lost during import where it is "converted" into an image. Is there a way I can bake additional data into the asset (ex: the complete raw svg text or some parsed svg paths) so I am able to retrieve it during runtime?

Basically is there a way I can extend an asset so I can still use it for it's built in purpose, but add some extra information that I can access during runtime?

I am currently looking into AssetPostprocessor and userData but am wondering if this is the best/easiest approach.

[vast vault]

My custom editor isn't "connected" to my scriptable object. How do I fix this?

There's also this issue

And when do I use EditorGUILayout vs GUILayout?

[surreal delta]

you cant initialize fields using other variables outside of functions unless that variable is static or constant

[surreal delta]

GUILayout is made for runtime UI, EditorGUILayout is for Editor UI

in most cases you want to use EditorGUILayout when writing custom editors, and use GUILayout for functions EditorGUILayout doesnt have like Button for example

[vast vault]

Ah, okay. Thank you. So how do I "connect" it to my scriptable object?

[surreal delta]

im pretty sure it is connected, to check that remove the base.OnInspectorGUI();

that would theoretically clear the entire inspector

[vast vault]

Nothing happens when I comment it out

[surreal delta]

hmm, thats odd

[vast vault]

The editor script is in the Editor folder, the other is in another folder

[surreal delta]

yeah thats fine

try putting a breakpoint inside the OnInspectorGUI function to see if it even runs

[vast vault]

How?

[surreal delta]

you click next to the numbers

make sure you attach visual studio to unity

[vast vault]

Nothing happens

[surreal delta]

by clicking that "play" button on top in visual studio

connect visual studio to unity

[vast vault]

"The breakpoint will not currently be hit..."

"Unable to find corresponding location"

[surreal delta]

huh, it seems that the script didnt compile?

if you go to the script in unity do you see the code in the inspector window?

[vast vault]

Nope. You're right

Even after reimporting it. After reopening it in VS it's empty

[surreal delta]

Did you not save?

[vast vault]

Yeah, but it was like I was editing a different script

[surreal delta]

Ah

[vast vault]

It said it was saved though. Now I don't know where

It looks right now. Thank you 🙏

[surreal delta]

i kinda had this issue happen before where unity didnt trigger the script compilation, i usualy force it to compile by editing another script

[vast vault]

Smart. How can I edit a serialized property of the target?

Is this valid?

How can I get the number of sprites in a spritesheet?

Does resources.load return null if it can't find it?

[surreal delta]

i think there is a function in the target called FindProperty

[surreal delta]

yes

[vast vault]

Thank you for taking time to answer my endless stream of question 😅 I really appreciate it

[surreal delta]

no problem, btw what are you trying to make with the custom editor?

[reef hornet]

Hello again
does anyone know a way to draw the default GUI of a property inside a custom PropertyDrawer?

[waxen sandal]

Can you elaborate on the use case

[reef hornet]

I'm trying to create a list of objects on a script
the objects have a base type they inherit from
if I set the base type for the list, I effectively cant add child-type objects into it
So I'm trying to achieve that with a custom property drawer, basically allowing to select a type of object I want to add to a list based on a base type

[waxen sandal]

So you just want to draw the fields of the instance or do you want to invoke the base unity property drawer (or any overriden ones?)

[reef hornet]

the problem I have is that I can't add child objects to a list of base objects with the regular + icon on a list in the inspector
I managed to add new objects when I mark my list as SerializeReference but then the GUI for the objects isnt drawn

oh nvm, i just didnt work with the regular + button, but it works with mine

[hollow ore]

I try to draw some handles, but OnSceneGui doesn't render at all 🤔 Any idea how to fix it? (Controller is abstract base class, and It's worth mentioning that OnDrawGizmosSelected works for component)

[CustomEditor(typeof(Controller))]
public class ControllerEditor : UnityEditor.Editor {
    // this works
    public override void OnInspectorGUI() {
        if (target is Controller { SdfScene: null }) // show warning if no SdfScene is assigned
            EditorGUILayout.HelpBox("This node doesn't belong to any scene", MessageType.Error);
        base.OnInspectorGUI();
    }

    // this doesn't even get called - no logs in console whatsoever
    private void OnSceneGUI() {
        Debug.Log("OnSceneGui called");
        Controller c = (Controller)target;
        Handles.color = Color.red;
        Handles.DrawWireDisc(c.transform.position, c.transform.up, 1.0f);
        // display object "value" in scene
        GUI.color = Color.red;
        Handles.Label(c.transform.position, c.handleValue.ToString("F1"));
    }
}

I basically copy-pasted the handle example from unity docs

[gloomy chasm]

Did you select the object?

[hollow ore]

yeah

[gloomy chasm]

And the OnInspectorGUI is getting called?

[hollow ore]

I did before, but I didn't check it again so let me check for a second

[waxen sandal]

Doesn't render or doesn't get called

[hollow ore]

doesn't even get called, but now that I checked something broke without me noticing, and now even OnInspectorGui doesn't get called. I'll first investigate that

ok, I did (???) and it started both drawing the inspector gui and handle

I see now what makes it bisbehave, but I don't understand why it's like that:
using Controller (which is public abstract class Controller : MonoBehaviour, ...) as a target for [CustomEditor(typeof(Controller))] prevents the custom editor and gizmos from drawing. Using concrete class, [CustomEditor(typeof(SphereSdfController))] works, however.

but I could swear that it worked before with abstract class??? Is there no way of using abstract class as a target for CustomEditor ???

[waxen sandal]

CustomEditorAttribute has an overload that says to also use it for derived classes

[hollow ore]

How did I miss that... Thanks!

[atomic sable]

Hey guys there's no way to change the editor log file output location right? I need to log some data to a file as a report and I figure it's best to just put it in a folder where all the other logs are

why are my lists still active with this? Attribute is on them.

    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        Debug.Log("test");
        EditorGUI.BeginDisabledGroup(true);
        EditorGUI.BeginProperty(position, label, property);
        EditorGUI.PropertyField(position, property, label, true);
        EditorGUI.EndProperty();
        EditorGUI.EndDisabledGroup();
    }

[waxen sandal]

Why do you have beginproeprty

[surreal delta]

attributes cannot affect collections, that will be supported in unity 2023.3

[atomic sable]

sadge

[ornate oriole]

I am kinda stumped with this one.

using System;
using UnityEngine;

namespace Yumi.Utilities.Attributes
{
    [AttributeUsage(AttributeTargets.Field)]
    public sealed class AltDrawAttribute : PropertyAttribute { }
}``````cs
using UnityEditor;
using UnityEngine;

namespace Yumi.Utilities.Attributes.Editor
{
    [CustomPropertyDrawer(typeof(AltDrawAttribute))]
    public sealed class AltDrawDrawer : PropertyDrawer
    {
        public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
        {
            //int indent = EditorGUI.indentLevel;
            //EditorGUI.indentLevel = property.depth;
            EditorGUI.PropertyField(position, property, GUIContent.none);
            //EditorGUI.indentLevel = indent;
        }
    }
}```
I'm trying to make an AltDraw attribute which basically just draws the field without the label (such as "Fade" on the image below). For some reason it has the correct indent in one place, but has no indent in another. Tried to fix that with the commented out code, which indented "Out" properly, but also indented "Fade" way more than it's supposed to. Meanwhile, it works fine when it's outside of an array.
Would appreciate it if someone tells me what might be going on here..

[atomic sable]

hmm... how do I make an Overlay refresh? There doesn't seem to be any refresh or redraw method I can call.

[gloomy chasm]

The depth is the serialized property depth. Hmm, not sure why it wouldn't be indenting properly, if you add a GUIContent with a label does it fix it?

[gloomy chasm]

What is the use-case? There is not a 'refresh' method, but ways to fix issues depending on what you are doing

[ornate oriole]

Here's with the label added

[gloomy chasm]

Could try positon =Editor.IndentRect(position);? But might also just be a bug

[atomic sable]

when the scene sis switched, I'm trying to assign a new SO to the overlay. This works, but it doesn't update visually until moved.

even this doesn't update it, but it still works:

Close();
containerWindow.overlayCanvas.Add(new PathDataBaker());

[ornate oriole]

Did you mean position = EditorGUI.IndentedRect(position); ?

If so, then it does nothing

[gloomy chasm]

Would try the latest lts I guess cause it is probably a bug

[ornate oriole]

I'm using the latest 2022 LTS

[gloomy chasm]

Could also try using UIToolkit if that would work for your case

[gloomy chasm]

I mean like 2022.3.16f

[ornate oriole]

2022.3.19f1 currently

[gloomy chasm]

huh, probably bug I thinks

[ornate oriole]

So nothing I can do with it I guess, I'll try looking at UIToolkit then

Thanks anyways

[atomic sable]

please someone tell me what I put here for a IntegerField to get this to work? I can't find what kind of event I need in the docs. I just want to register a callback to this integer field when the value changes so I can actually update my variable in my overlay. They shouldn't have made it this hard.

[visual stag]

Why not just use the register change event?

So you don't have to know the event type

[atomic sable]

I don't see any event of such type

[visual stag]

It's a separate method

[atomic sable]

why is this an extension method!?!? I'm looking at the docs and there's nothing about this!

specifically this page:
https://docs.unity3d.com/ScriptReference/UIElements.IntegerField.html

felt like I was going crazy

thank you

[severe plinth]

Is this accessible via code, can't find it in PlayerSettings.Android or EditorUserBuildSettings?

[lethal imp]

Hi I’m using the serialized reference to show different classes on the editor, but the dictionary that I use, when adding a key, copy all the serialized property, including the serialized reference, into a new object in the dictionary, so now I have two object with the same serialized reference, how can I avoid this ?

[daring temple]

Hey guys, so someone from another channel pointed me to this link: https://github.com/Unity-Technologies/UnityCsReference/blob/master/Editor/Mono/Clipboard/ClipboardContextMenu.cs

Because i was asking is is possible to copy a component without physically right clicking and clicking copy. So is it not possible?

Oh i see now there is a clipboard utility; anyone know how to use it and if it can be used to say copy the color red to the clipboard in code and then be able to paste the red on to a serialized color in the inspector

[acoustic dragon]

Hey, I need to display scriptable object's inspector inside my EditorWindow, I know other assets managed to do it, how can I accomplish it too?

[gloomy chasm]

I think this supports custom editors, so should do https://docs.unity3d.com/ScriptReference/UIElements.InspectorElement.html

[acoustic dragon]

It worked, thanks you!

[vast vault]

I need an array of sprites in an animation. Instead of dragging and dropping every frame in the inspector, it would be nice to have a button to do it for me

[surreal delta]

uhm...you can just grab all of them and drag it on the array

[vast vault]

Really?

I wish I had known

I still can't get the Resources.Load() to work

Sprite loadedSprite = Resources.Load<Sprite>($"{spritesheetPath}");``` This is the code

if spritesheetPath is Water_1, it returns Water_1_0. But I can't get Water_1_1

[vast vault]

It works now. The solution was to use Resources.LoadAll()

[vast vault]

How? When I select one sprite, the script is removed from the inspector?

[surreal delta]

lock the inspector

[alpine bolt]

Off-topic: You can create a detached inspector

[vast vault]

Amazing! Thank you both

[muted cave]

I'm trying to make a custom property drawer. The first horizontal works fine, but as soon as I add a second horizontal group it bugs out.
https://hatebin.com/anoylynams
What am I doing wrong?

[gloomy chasm]

Two things, first you can't/shouldn't use any GUIlayout methods inside of a PropertyDrawer, second, you need to returnthe property height, can't just return 0

[muted cave]

Any value above 0 just adds an extra space to it. And what's wrong with GUILayout and what is the alternative to that?

[indigo condor]

how could i solve this? the down page is supposed to expand to the bottom of the window... and it also gets over the header... i'm loading the page in a uxml under the header uxml... this is the code... any ideas? https://paste.ofcode.org/39z95CtaQb6bt6jm4qvUgML

[gloomy chasm]

Any value above 0 just adds an extra space to it
Because you are using GUILayout.

And what's wrong with GUILayout
It can't calculate the layout correctly in some scenarios. Like you just found out.

what is the alternative to that?
Using the non Layout classes GUI and EditorGUI and calculating the rect manually.

[gloomy chasm]

The header container probably has flex shrink set to 1 if I had to guess

[indigo condor]

Later I try it, thank you!

[glad pasture]

Is there any way to differentiate in the Editor between 1) a normal base prefab instance and 2) the base prefab instance inside a variant in prefab mode?

Hierarchy of 1 looks like this in the scene or when a another prefab it is contained in is opened:

• scene or other prefab
  • instance of the base prefab or variant

Hierarchy of 2 looks like when the prefab is opened:

• variant prefab context
  • instance of the variant's base prefab

My use-case is that I need to validate that any instance of that prefab "family" has a specific property set, but hiding the error when a prefab of that prefab "family" is opened in prefab mode.

[surreal delta]

you can open the properties of one prefab in a separate window then select the other prefab and compare them

[glad pasture]

Yeah, sorry, I guess I was unclear. I meant from code. I can't seem to find a combination of PrefabUtility or PrefabStageUtility functions that would allow me to differentiate the two cases.

[hollow ore]

can I attach a sub-asset to a prefab? Essentially I have a prefab with root having a certain kind of script, that has a runtime part and editor part. The editor part creates a Shader asset and potentially material asset, that should be specific to this prefab only. How can I do that?

[indigo condor]

header is already like that...

[gloomy chasm]

I know, that is what I am saying the issue is. flex-shrink means that the VisualElement can shrink smaller if other elements need more room. Setting it to 0 disables this function.

[indigo condor]

i've tried to change it and it still getting over the header... :>

[indigo condor]

any more ideas...?

[gloomy chasm]

There are too many different things it could be. Still pretty sure that is the issue though. I would open the window up in the UIToolkit Debugger and play around with different properties to get a better understanding.

[indigo condor]

oh, nice... i think i've got it... wich shrink is that one?

cause that one really affects the header

[gloomy chasm]

You mean where is the TemplateContainer coming from?

Also these links will help with understanding the properties
https://docs.unity3d.com/Manual/UIE-USS-Properties-Reference.html
https://docs.unity3d.com/Manual/UIE-USS-SupportedProperties.html

[indigo condor]

exactly

cause here there are not template containers...

[indigo condor]

i'll take a look at that too

[gloomy chasm]

When you do CloneTree it creates the TemplateContainer. This is because you can have multiple VisualElements at the root level in a UXML file (like if you had a "Body" element under your "Header" element).
So, it puts them all in a TemplateContainer. You can avoid this by pass in in a VisualElement to the CloneTree method that it should add it.

[indigo condor]

oh, done it! thanks!

[atomic sable]

Hey guys... editor prefs are suppose to be saved between sessions correct? Mine are not.

in a SettingsProvider:

deactivateHandler = () =>
{
    s_cellCheckHeightField.UnregisterValueChangedCallback(CellCheckHeightValueChanged);
    s_useInactiveObjectsField.UnregisterValueChangedCallback(UseInactiveObjectsValueChanged);

    EditorPrefs.SetFloat(cellCheckHeightKey, s_localCellCheckHeight); // save value
    EditorPrefs.SetBool(useInactiveKey, s_localInactiveObjects); // save value
},

perhaps they're not being set for some reason?

(the local values are saved because I can see the values when closing/opening the settings, but when restarting unity I do not see the value)

ah I see, just solved it as soon as I ask here as usual. Turns out the deactivateHandler is called before activateHandler for some reason. I falsely assumed deactivateHandler would only be called when closing the settings.

[indigo condor]

Good night everyone... Does anyone knows how could i change clicked buttons anims?

[gloomy chasm]

look in to UIToolkit transitions

[indigo condor]

Tomorrow I take a look at it

[atomic sable]

how do I properly use ITransientOverlay? Right now I have this, but when I create a new instance of my overlay and set these two bools to true, nothing happens.

public bool visible => isVisible && isValid;
public bool isVisible = false;
public bool isValid = false;

[dawn root]

Is it safe to set an asset's labels Onvalidate? I want to keep it synced with a list on the SO

[indigo condor]

But why is it that when I hover my mouse over the default button it does stand out and when I hover it over a button that I have changed the color of it, right?

also, how could i remove the border when it's clicked?

[gloomy chasm]

Ahh, then you want to look in to pseudo states, like :hover

[indigo condor]

and where is that?

[indigo condor]

you mean by code?

[gloomy chasm]

https://docs.unity3d.com/Manual/UIE-USS-Selectors-Pseudo-Classes.html

[indigo condor]

ohh, suree... and do you know how could i change who is the anim for?

[gloomy chasm]

What do you mean?

[indigo condor]

i want the green anim to apply to the hover, and the red anim to the active

[gloomy chasm]

Btw, if you just want to change the color or other properties, you don't need to use the Transition Animations.

The animations are applied when the uss class is added to a visual element.

[indigo condor]

that's done

[gloomy chasm]

So as soon has you mouse over, the :hover pseudo class is added which will play the animations.

And if you add a animation to the .pages-button:active selector, it will be played as soon as the button is pressed

[indigo condor]

yeah, the thing is that i don't want the .pages-button:active to have any kind of duration...

that's why i've created two anims

[gloomy chasm]

You just want to have different style properties when the button is active, yes?

Then you just change the properties and don't touch the animations

[indigo condor]

Hmm... right now, when i pass the mouse over the buttons (hover) they need 0,5 secs until the color changes completly, and that happens too when i click on them (active), but with another color.

[indigo condor]

What I want to happen when I click on them is that they don't take 0.5 seconds to change color and be direct

[gloomy chasm]

So you just set the property and don't touch the animation stuff....

[indigo condor]

hmm, let me try it :>

[indigo condor]

does someone knows where does the underline come from?

[fickle comet]

How do you use this? https://docs.unity3d.com/2021.3/Documentation/ScriptReference/UIElements.ObjectField.html

No mater what i do it says its deprecated

It says to look at the docs but the docs literally say nothing

(unless i'm blind)

[vocal steeple]

hello, how to solve this ? I have a script, but I cannot press a button in inspector because its a broken size....

[gloomy chasm]

Show the code please.

[gloomy chasm]

Probably are not calculating the height properly. Can you show the code.

[fickle comet]

https://hastebin.skyra.pw/uwaxowexel.csharp

I converted it from something else, its why most of the stuff is on the bottom

[gloomy chasm]

Yeah as I thought, you are looking at the wrong docs. That is the docs for a UIToolkit elements, this is what you are using https://docs.unity3d.com/ScriptReference/EditorGUILayout.ObjectField.html

Just the specific overload you are using is depricated

Specifying the type and if scene objects are allowed is required

[fickle comet]

Thanks

[fickle comet]

Is there a way to show it like a list in the inspector?

[gloomy chasm]

You need to use a ReorderableList. It is a bit of a pain though. Really, I recommend using the new UIToolkit UI system instead of the IMGUI system if you can.

[fickle comet]

I would but its for a jam, maybe later. I don't even need that much functionality, i'm just getting distracted :)

I had the project open for hours and i haven't added a single game related thing

[mystic wigeon]

Think I found out how to fix it but Im not completely sure

Im checking it this afternoon though

Youre supposted to open the button on the Unity UI Toolkit editor, select the VisualElement component and, in the Pseudo States section, uncheck the Active checkbox

[vague spear]

Hey! I need help.

How do you save variables that have been changed through a monobehaviour function that is called from an editor button?

I have a "Item" and "Manager" script with editor scipts. The manager has a button in it's inspector that loop through each Item script in scene and calls a method in the "Item" script that updates it variables.

Have this setup going and doing it in editor updates the variable but hitting play resets the variable change from the "Manager" button. To add, "Item" objects are prefabs.

[indigo condor]

heey, thanks! :>

[blissful burrow]

does anyone know if it's possible to clip Handles.DrawLine() to IMGUI rects?

I kinda expected them to behave the same as GUI.Label etc, where they clip to the GUI.BeginGroup rect

rn they are rebellious and draw outside their bounds, unlike the label

[visual stag]

I have to ask, why are you not using UIToolkit, where it has its own vector drawing API?
Also, I don't think there's a way to provide your own material for Handles is there? I remember doing work with textures ages ago and facing a similar issue, and had to make changes to a material https://github.com/Developer-Notes-Extension/Unity-Notes/discussions/23#discussioncomment-2931708

[blissful burrow]

because I'm too lazy to learn UITK

maybe I should lol

what's the UITK drawing API?

oh I found it I think (https://forum.unity.com/threads/introducing-the-vector-api-in-unity-2022-1.1210311/)

[visual stag]

As it's been the recommended solution for a few years now, you definitely should 😛

I would not be surprised if IMGUI is removed in coming major releases

[blissful burrow]

uuuh I can't find example code for how to set up data bindings for object fields hmm

oh, BindProperty

is this the nicest way to do it for editorwindow or is there a shortcut?

ObjectField meshField = new( "Mesh" ) { objectType = typeof(Mesh), allowSceneObjects = false };
meshField.BindProperty( so.FindProperty( nameof(mesh) ) );```

[visual stag]

Is there a reason to not just use a PropertyField?

[blissful burrow]

yeah, I didn't know it existed as a separate thing

ok now it no longer shows up

[visual stag]

For Editor you would use PropertyField and set their bindingPath to the property path and then Unity calls Bind at the end with the SerializedObject

If you're writing an EditorWindow you need to call Bind yourself at the end on the root of your elements, which will cause UITK to create the contents of the propery fields

[blissful burrow]

right

yeah now it works

ok, next up, how would I create a space-filling region with a specific GUIStyle?

I was using EditorStyles.textArea with expandwidth/height before

[visual stag]

GUIStyle isn't a thing. Style it with USS however you want, just set flex-grow to 1

[blissful burrow]

is there no way to access unity's USS styles?

(for things like text area)

[visual stag]

They're just class names, so yeah, just look at one using the UIToolkit Debugger (see the Styling Elements pin in #🧰┃ui-toolkit ) and find what classes are added to what, and what the selectors are doing

and then AddToClassList whatever class has the styling that performs the work

[blissful burrow]

oh right I should prolly be in the right channel

[visual stag]

🤷 it's relevent enough to both channels

[blissful burrow]

I should probably save this for tomorrow c:

its getting late

thanks for the help!

[peak bloom]

Every time I went back to this channel and saw people asked imgui stuff, I was like "Why?"

[blissful burrow]

look,,

I've been using imgui for a decade lol

let me use my comfort tool

[waxen sandal]

Imgui is pretty nice and quick to work with

UITK is so much effort to set up things

(and considering this is the #↕️┃editor-extensions channel, most of the work is not big UI projects)

[visual stag]

It's nice and quick but imo most people are still using it to do the most redundant and over engineered tools by making complete editors all the time.
Once you are making most things property drawers then you suffer by having to deal with GetPropertyHeight and manual layout, which is just a non-issue with UITK

[hollow ore]

is there some way to make changes in SOs be detected in mono-behaviors in the editor, that have [ExecuteAlways] ? I am changing one bool in SO that I reference from an component on a game object in the scene view, but the script doesn't see that SO changed and doesn't refresh in any way

[surreal delta]

you can try OnValidate

its called on every inspector property change

[hollow ore]

I have OnValidate on game object, at it's not triggered when SO changes. For OnValidate inside my SO, I am not sure what to put there. I tried AssetDatabase.Refresh(), but it didn't do anything

[cinder rivet]

Hello, from an Editor script I'd like to determine if there are any dirty and unsaved scenes in the Hierarchy, could someone please point me towards some guidance on how to do this.

I've gone through EditorSceneManager and all I could find is a function that asks the user if they want to save any modifed scenes, but its not ideal for my needs, I really want to just find out if there are any modified scenes or not.

[waxen sandal]

If you can somehow get a list of opened scenes you can use https://docs.unity3d.com/ScriptReference/SceneManagement.Scene-isDirty.html

[cinder rivet]

Thanks Navi

[cinder rivet]

Ah yes, that looks like it will work, I found some example code using that isDirty and SceneManager.GetSceneAt() that looks like it will be ust what I need 🙂

https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.GetSceneAt.html

[waxen sandal]

Yep that's the one

I knew it was somewhere just didn't remember where 😛

[cinder rivet]

I'll just put it here, in case anyone is searching the channel later:
Find if any scene has been modified..

bool IsAnyScenesDirty()
{
    for (int n = 0; n < EditorSceneManager.sceneCount; ++n)
    {
        if(EditorSceneManager.GetSceneAt(n).isDirty )
        {
            return true;
        }
    }

    return false;
}

[rugged urchin]

How do I author an editor script which starts play mode, and then runs some code in play mode, and then exits?

More specifically, how do I create a MenuItem or a method meant to be run from the CLI that does the following:

EditorApplication.isPlaying = true;
// in pseudocode - I know how to do these
await applicationIsPlaying();
await waitOneFrame();
doSomeOtherStuff();

the essential challenge here is that EditorApplication.isPlaying = true; seems to cause a domain reload in the editor when run from a editor menu item.

this is surprisingly challenging because I've tried:

instantiating a game object, adding a component, then setting isPlaying=true: the component's start runs in edit mode, and is not run again in play mode

the playmodechanged callbacks: the domain appears to be unloaded, so the modification to that static variable is lost

i feel like this is something people want to do all the time, so I am surprised it is very hard

[fair cove]

I wonder if it trulyis the right place to ask but here we go :

I am currently coding an Editor Window, somethign kinda basic, I use a UXML document made with UIBuilder and its USS selector, and I manage the logic with C#, nothing unusual so far.

The real problem is that I'm using ListViews (I have 9 elements, 7 of which are elements generated by the ListView because the ListView's recycle system bind/unbinds elements depending on which it needs to show, I noticed that if I scrolled all the way down and continued scrolling some more and then press a button to simply Rebuild() the List, my "unbindItem" method would return me a -1 index at the end :

it's not much of a problem normally but if I add my Register/Unregister callback management logic it would then try to access and invalid index and return null, I'm saying it again but the screen is a most simple ListView with 9 elements

the Dictionary being a <string, bool>, I tried with another editor window with a List<string> and it was the same

[gloomy chasm]

Just set a bool or something in either SessionState or in a custom ScriptableSingleton and use the EditorApplication.playModeStateChanged event

[dawn root]

Is it possible to move an existing scriptable to nest it inside another scriptable? I have scripts that reference the SO I want to nest and want to keep them.

[chilly steeple]

I am getting "NullReferenceException: SerializedObject of SerializedProperty" errors when I want to set my editor asset to dirty. Stack trace indicates something went wrong in the UIElements part, potentially in a list. Anyone know work arounds?

[waxen sandal]

Sounds like you're trying to use serializedproperties and direct object access to modify the object at the same time

But without more info we can't help more

[waxen sandal]

Yes, AssetDatabase has some methods to make child assets

[chilly steeple]

could you explain what this means? I'm happy to explain more, too, about the structure of my data but so far this error only pops up when the inspector is open of the object I am trying to SetDirty

[waxen sandal]

Can you post the stacktrace?

And do you have a custom editor?

[chilly steeple]

Yes, one second.

And no, it is not a custom editor.

[waxen sandal]

That's interesting, guessing that's just a bug in the version of unity you're using

[dawn root]

I've been using AssetDatabase.AddObjectToAsset() when creating new SO instances. is there an equivalent for nbesting existing SO into another?

[waxen sandal]

Probably need to load it, delete the instance in the assetdatabase then add it to the new parent

[chilly steeple]

[waxen sandal]

yeah that's a bug in Unity

If you cant update, chances are you can just use Selection.activeSelection to deselect it first

[chilly steeple]

Haha didn't think of that workaround, ill try that

its a lil unfortunate that UIelements seems to be causing issues still, not very stable yet compared to regular GUI

[waxen sandal]

I mean itcan also happen in IMGUI

OR you can switch to using SerializedObjects to update your asset

Which is the recommended way anyways

[chilly steeple]

I don't know enough about it, but from my own experience Lists and Arrays in UIElements of sizeable length are really slow, an issue we did not encounter back when the editor was GUI based.

Hmm, so I should create serialzedObjects for my data classes?

[waxen sandal]

IMGUI is slow too, arguably slower since it can't do culling/updating only changed elements

Yeah, create an so, find hte property you want to change, change it, apply changes

[chilly steeple]

again, sure, but my list of graph nodes wasn't making my editor lag like crazy when it was GUI

[fair cove]

How can I fix the -1 index ? 😔

[cinder rivet]

Hi, I'm using this method EditorSceneManager.UnloadSceneAsync

And it returns an AsyncOperation, but I'm not sure how I'm required to handle that.

I want to unload a scene, and then wait until it is unloaded from an editor script ( not in PLay mode ).

As imple test of

AsyncOperation async = EditorSceneManager.UnloadSceneAsync("myScene");
while( ! async.isDone) {};

Just ended with Unity hanging in a inifinite loop.

Perhaps I need to use an Editor Coroutine?

[alpine bolt]

Have you tried wrapping around an async void method?

[cinder rivet]

I haven't, actually, I'm not sure what wrapping around an async voide means, is that something I can google?

[alpine bolt]

private async void WrapMethod() {
    AsyncOperation async = EditorSceneManager.UnloadSceneAsync("myScene");
    while( ! async.isDone) {};
}```

[cinder rivet]

Oh, ok, and then would I call that WrapMethod() in a particular way?

[alpine bolt]

It really depends on what you are doing, but when using this code, you wouldn't want to run it on the main thread.

AsyncOperation async = EditorSceneManager.UnloadSceneAsync("myScene");
while( ! async.isDone) {};```

[cinder rivet]

Ok thanks for your help with this, I'll go. off and read the documenation and see if it is what I'm looking for, I think it probably is,

[alpine bolt]

Normally, a -1 return for indexes works as false or as not found

[fair cove]

Would simply putting a return statement when such situations occur be enough then ? 🧐

[alpine bolt]

If there's a -1 index return, treat it as a false/null/not found. Maybe you should ask here #💻┃code-beginner

[fair cove]

I mean it's related to the workings of a ListView which is commonly used in editot extension so I thought this was a better place to ask tbh, also the ListView is part of an EditorWindow script

[cinder rivet]

Is there a recommended way to persist Editor script variables across shutting down / starting up Unity again?

My needs are very simple today, I just want a single string to maintain its value.

[waxen sandal]

EditorWindow?

[cinder rivet]

Yes

[waxen sandal]

If it's serialized properly then it does

[cinder rivet]

So, I just need to add [System.Serializable] or it will just work with a string anyway?

[waxen sandal]

Idk how your current code works so can't tell you that

It's the same rules as scriptableobjects basically

[cinder rivet]

Ah ok, thanks again for your help.

[fair cove]

A [SerializeField] could also work depending on your code

[cinder rivet]

Thanks again for everyone that has been helping me today. I think I just got my tool finished.

Its a little window where I can choose different build configs ( iPad, iPhone, Meta Quest, Steam VR, Mac ) and it loads all the scenes I need for each of those individual configs.

Plus the main thing, is it exclude folders that would have build errors, like Oculus stuff from being included inthe iOS targets.

Then finally it just adds the required scenes to Build Settings, and then changes the target in there as well.

[peak bloom]

any idea why this would appear out of nowhere

no error, it used to be ok

restarting editor didn't do anything either

I've a feeling that removing .meta file might fix it

[visual stag]

Presumably one of the possible options https://unity.huh.how/script-loading-issues
Or something isn't importing at all, if some packages aren't importing (their folders look empty) then you'll need to do a Reimport All

[peak bloom]

I guessed it right, removing the .meta file fixed it

it's fine now

thanks for responding Vertx 👍

[visual stag]

Deleting a meta file seems unnecessary 👀
I don't know what state it could be in that could require that, as if you were using it across the project that would be a very disruptive change

[peak bloom]

it's just for dummy testing,, nothing important and just this one problematic component

[waxen sandal]

Wrong channel

[wheat vale]

Which channel is the right one?

[waxen sandal]

Idk, probably #💻┃unity-talk or maybe #📲┃ui-ux

[surreal delta]

is there a way to use GUILayout/EditorGUILayout functions for array elements without positioning them outside of the array?

[keen tiger]

Hi, I'm trying to adjust build settings via an editor script for a WSA project, I can't seem to find where I would set the value for "Build Configuration", could someone help me out? Most of the WSA settings can be set via EditorUserBuildSettings, but I can't find this one

[waxen sandal]

What?

[surreal delta]

if i use EditorGUILayout functions via custom attributes to position array elements they draw after the array instead of remaining inside it

[waxen sandal]

Are oy making a propertydrawer?

[peak bloom]

can somebody explain what this api is for ?
https://docs.unity3d.com/ScriptReference/EditorApplication.Step.html

just curious, like for what use cases?

[waxen sandal]

It's the button next to the play/pause button

To execute one frame worth of gameplay

It's useful if you're trying to monitor on a frame by frame basis

[peak bloom]

oh I think I can use this due for a fact I'm making a tweening lib that works for both edit and plat mode

thanks, Navi 👍

[waxen sandal]

Your welcome?

[fair cove]

Hello, I've found the solution to my problem so I'm here to share it with everyone if it helps.

Basically I was doing this after changing the itemSource of my ListView :

ListView.itemSource = List;
ListView.Rebuild();```

it may seem logical at first when changing the List to assign it again and then Rebuild() except that assigning a new itemSource, already """Rebuilds""" the ListView, the problem with Rebuild is that it will try to Rebuild **all visible elements** which means that if you go all the way down and then rebuild it will try to rebuild an element after the last one of your list (which doesn't exist) and therefore return a -1.

so a security to prevent a -1 index isn't needed if you just use :

```csharp
ListView.itemSource = List```

when you want to refresh your ListView after changing the List

[peak bloom]

iirc listview will only rebuild for the 1st time you assigned the itemSource, the next one you should rebuild it manually

and nothing wrong with rebuilding over and over, they're pooled

the impact will be very minimal

[fair cove]

In my case for some reason (even after removing all logic I added) when I scrolled all the way down it tried to rebuild and element that wasn't there, returning -1 even if the List wasn't changed in length

Maybe there is a small difference between asigning new itemSource and Rebuilding ?
Also I just tested and assigning a newItem source works each time

[peak bloom]

no, that's a common mistake with listview

it's due to pooling that ListView is doing, so it's recycling all of it's resources (elements)

if you assigned a delegate/events make sure to clear them before changing the itemsource

OR use unbindItem to clear them all

it's the same process as you'd with bindItem except it's for housekeeping purposes

unregistering events, delegates etc

you must make sure all those gets cleared/unsubscribed so when the next it gets reused won't cause issues and what not

I'm baffled on why Unity never officially put this in their docs

[surreal delta]

yes

[waxen sandal]

You can't use guilayout then

Gotta calculate rects manually

[surreal delta]

damn

maby it would be better to use UIElements for those cases

[fair cove]

I know that Unity's ListView works by pooling element and the Unbind Item and Bind Item are even called automatically after you change the itemSource and/or use Rebuild().
I custom made my own UnbindItem and BindItem and somehow didn't have any troubles without Rebuild() but if I put Rebuild() with itemSource actualisation or just alone if you scroll all the way down it will return a -1 at some point.

I don't have this problem without Rebuild() so I'm only guessworking here that Rebuild() is trying to unbind an element that doesn't exist and therefore returns a -1.
As it doesn't do this when the view is situated in the middle of the List I'm guessing that it's trying to find an element after the last one when you are scrolled all the way down, I could be wrong though 🤷

Here's my code if you want (these function manage all of my ListViews simultaneously that's why there is a 3D array):

[timber stump]

This might be a really stupid question, but can I use AssetDatabase in the constructor of a custom attribute?

I want to check for the existence of a ScriptableObject and create it if it doesn't exist.

I guess I could just use #if UNITY_EDITOR actually

[fair cove]

I mean nothing prevents you from doing a call in a constructor

And also the conditional compilation wouldn't solve this though ? Just check if it exists and if it does then create the scriptable if you want to put the conditional compilation then you're better off creating an Editor folder in your project and sliding editor scripts in

[timber stump]

Well I'm trying to use reflection to get all methods with an attribute. I've managed to make it work and improve the speed by filtering assemblies and only searching relevant ones, but it still drops frames from 300-ish to 200 for a few frames. I was considering using a scriptable object to store all of the relevant info.

Buuut maybe not worth it. Idk.

[fair cove]

Can't you use a diffetent method from the reflection one ? Also is it in editor mode ? If it is framerate drop are way less important than at runtime. Also if you do the reflection operation multiple times it is indeed wise to store data in a scriptable object to avoid multiple calls to a heavy function

[timber stump]

I do it once on Start() when my in-game command terminal scene opens and cache the results. It would be run once any time the terminal opens, but I was thinking of catching the results in an SO so that it only has to perform the search once per session.

I am basically trying to make an in-game command terminal. I already have one, actually, but I am making an attribute for methods to run in the terminal. Basically:

[RuntimeCommand("commandPrefix")]
MyFunc()

And at Runtime in the terminal:

commandPrefix.MyFunc

Again, this actually works now I'm just trying to more efficiently get the commands at Runtime.

My thought is that the constructor for.the attribute is... Probably(???) called in the editor when you apply the attribute to a method, so you could just create an SO if it doesn't exist and add the serialized info to it then.

[fair cove]

I my opinion you should try to avoid using the reflection method or use it in editor mode, storing the results in a scriptable is a very good idea though regardless of the rest, you should create the scriptable in a specific folder and keep the path to it to very quickly check whether the folder is empty or not

[fair cove]

Mhm yeah it would be logical for the constructor to be called in editor mode

[timber stump]

That's sort of what I was thinking, yeah.

[fair cove]

But I'm not a unity specialist so I can't tell you for sure

[timber stump]

I'm guessing the SO needs to be in the resources folder.

I can try debug statements to check I guess haha

[fair cove]

Mhm whatever folder you want tbh

As long as it's not the Editor one

[timber stump]

I've been working with Unity for a long time. I can get it to work I just was looking for feedback or to bounce ideas off of another person I guess.

[fair cove]

Yeah ik what you mean 😭 as second pov is often good to take

Also you could create the SO and reference it in your script

So this way you can check even faster if it exists or not

[timber stump]

Well if the SO is only referenced by the terminal, then unloading the scene would also unload the SO from memory, right? So it would defeat the purpose of caching the reflection results. I was thinking of serializing the results of the reflection search as strings so that all of the methods are stored before you even build

Obviously reflection would still be required to invoke the methods though.

[fair cove]

I don't think the SO would be deloades unless you do it explicitly since it stores data.

The objective would be to find your SO the first time you need it, if not create it. And then keep it as a reference for further use, if you go back to editor mode the SO would still be instantiated and have its data I believe

nvm you'd have to use JSON I guess since this will persist in editor mode in this case you'd need to write/read from a JSON file but you'll have everything you want

[wicked orbit]

Quick question - anyone know how to disable Unity scene view camera movement temporarily?

I'm trying to make an editor tool where pressing shift + the scroll wheel in the scene view does something. Only problem is that also moves the camera and I don't want to move the camera just in this context.

[real spindle]

Does it work if you just .Use the current event?

Whenever you shift+scroll

Also I have used HandleUtility.AddDefaultControl(-1) to disable scene view controls, in the layout event IIRC

[wicked orbit]

Just tried it, .Use does indeed work. Thank you very much for the help!

Is there a simple way to make a build from an editor script, I just want to basically press ctrl+B , but I'll implement a better system using BuildPipeline at a later date.

[wanton arrow]

Hey everyone! I want to make a system where I can visually edit my custom state machines. What would the best way to go about create an asset that stores all of the data be? I will need to store states of varying types and as far as I know that cannot be serialized into a scriptable object

[real spindle]

Would it be like a graph?

[wanton arrow]

basically

I just dont know how to store data like that

[real spindle]

I personally use a Graph : ScriptableObject
Which has sub-assets that are Node : ScriptableObject
Or 'State' instead of Node

[wanton arrow]

hmm but

[real spindle]

Then I Instantiate it at runtime

[wanton arrow]

wouldn't that create a shit ton of asset files? or is it all contained within one file

[real spindle]

Hence sub-assets

[wanton arrow]

whats a sub asset

[real spindle]

A child asset basically

[wanton arrow]

ohhh

inch resting

so how would I do that

bc if i have a reference to another scriptable object it will just be like

ok drag an asset here to reference

[real spindle]

Not sure what you're asking tbh

[wanton arrow]

how do sub assets work like how do I make an asset with sub assets

is there documentation about this

[real spindle]

AssetDatabase.CreateAsset for creating the graph asset, then adding sub assets with
AssetDatabase.AddObjectToAsset

[wanton arrow]

ohhhh ok

[real spindle]

Or EditorUtility.CopySerialized if you want to overwrite an existing graph asset

You gotta get a bit familiar with editor scripting

Took me a while to get there

[wanton arrow]

Ive done some but mostly inspector stuff

not a ton of asset stuff

[real spindle]

Yeah, google around and see how other people do it

If you have issues, ask here. I'm not an expert but I managed to get it working

But there are some editor wizards on this channel

[wanton arrow]

coolio

ty!!

[wanton arrow]

How much of this do I have to do myself

Is there an api to have a like workspace where I can scroll around and zoom in and have things I can click on

something like the animation controller but simpler

VSCode Extension - Clover is released 0.0.12
repo : https://github.com/novemberi/clover

[fierce jewel]

why is vscode so frustrating

[waxen sandal]

Because it's a glorified text editor

[shut juniper]

how can I simulate or replicate regular Update rate in editor script? like with EditorApplication.update delegate, but with less calls than it do, because I want to simulate an Update for testing purposes without Monobehaviours (I'm using ScriptableObjects for some stuff that needs some update when testing) and EditorApplication.update is running way way too fast, lol
is it possible? I'm not very good at editor scripting, so I dunno how to do it properly with these restrictions

[hardy apex]

does anyone know how to change a project's editor loading screen? Like when opening the project in the editor? Trivial to do in Unreal, having trouble finding resources on doing this in Unity

[dusk portal]

pretty sure that's a no go, it's built into the editor and you don't have the engine source unlike unreal

[gloomy chasm]

What? EditorApplication.update only runs like 15 times a second (15 fps). Which is way slower than a MonoBehaviour.Update method, so not really sure what you are looking to do. Also, if it is for testing, have you looked in to Unity's UnitTest framework? Works great for entering-exiting playmode automatically and cleaning stuff up.

[alpine bolt]

If you think it’s too fast for what you’re doing, just skip some calls arbitrarily with a counter

[peak bloom]

it's more than that and kinda flaky (inconsistent)

[gloomy chasm]

Its 15, 24 or 30, I can never remember (still way less than runtime Update). Yeah the update speed is also related to the editor speed, just like MonoBehaviour Update is related to the runtime speed

[peak bloom]

you can just do it like this

            var time = EditorApplication.timeSinceStartup;

            if (time < (lastTime + (1 / screenRate)))
            {
                return;
            }
            
            lastTime = time;

In the example I'm faking/simulating 1 frame based on screenrefreshrate, you can change it to whatever timing you want.

[queen wharf]

Is there a way I can call things like EditorGUILayout and GUILayout in an extension to EditorWindow?

I could be wrong but I think it's causing me to crash

(which makes sense i suppose maybe)

or at that point should I just make a class that inherits from EditorWindow and store helper functions/extensions in that

[gloomy chasm]

If you just want to access the methods without having to specify the class, you can just use a static using statement

using UnityEngine;
using UnityEditor;

using static UnityEngine.GUILayout;

public class MyWindow : EditorWindow
{
  private void OnGUI()
  {
    if (Button("Some Button"))
    {

    }
  }
}

[hollow ore]

When I write my package, how do I make my scripts display with my icon instead of the default C# script one?

I want my icon instead of the white paper with #, just like Mesh renderer and others

Ah, I already have it working, I just didn't notice that this exact script wasn't derived from my other with [Icon]

[gloomy chasm]

Click on your script file and in the top left of the inspector click on the icon and change it

[hollow ore]

so if anyone else looks for that: use [Icon("...")] on your mono behavior

[hollow ore]

yeah, that also works, but when I write I package I have to use [Icon] for my scripts to have this icon by default, without user having to assign it manually

[gloomy chasm]

What? That shouldn't be an issue...

[hollow ore]

ah, because icon is stored in the script's .meta and retained when I share my code as package, right?

so those two methods should be viable

[gloomy chasm]

Yeah, actually I think it is stored in the object file but I don't remember for sure. Either way it should be fine

[slow wing]

Is there a way to suppress the Importer(TextureImporter) generated inconsistent result warnings for a custom AssetPostprocessor? My postprocessor's output is based on folder name among other things and gives me a warning any time a directory/file is renamed + reimported

[slow wing]

^ update: this is apparently not coming from my importer - the plot thickens
^ update-update: definitely coming from mine. not dodging the blame on this one

[wanton arrow]

two questions:

a) why is the subasset not reflecting the name of the scriptableobject

b) I have this custom ui element and I want the label to reflect the name entered here. whats the best way to do this?

do i subscribe to the serialized property on the object? is there an ongui method I can override?

[royal meteor]

So I'm thinking about going down a BIG rabbit hole, does anyone know how much of my life force I will lose, if I actually try to code a script for fully procedurally destructable objects?

[wanton arrow]

def depends on how much expirence u have

[royal meteor]

I don't have tremendous experience, but I feel like I could (maybe, potentially, probably not) figure it out

OHH

Wrong chat lmao

I meant that for #archived-code-advanced

[gloomy chasm]

Try calling AssetDatabase.Refresh() after changing the name

[wanton arrow]

I manually refreshed and it didn't update

[gloomy chasm]

Assuming this is for UIToolkit. If you make a SerializedObject of the ScriptableObject, then you just bind the Label element to the name property

[wanton arrow]

I actually figured that out and tried it but it doesn't work

I think because labels dont have a value

its the "text"

but tbf I tried it with a textinput and it didn't work either so maybe im just doing it wrong

[gloomy chasm]

No no, it definitely does work

[wanton arrow]

I set the binding path to name

and then uhhhhh

set the bound object to a serializedobject of the state

[gloomy chasm]

Did you bind to the serializedObject?

[wanton arrow]

but no dice

I think it may be bc name isn't a normal serializedproperty but idk

[gloomy chasm]

Label myLabel = new Label();
myLabel.bindingPath = "m_Name";

rootVisualElement.Add(myLabel);
rootVisualElement.Bind(serializedObject);

[wanton arrow]

its an existing element

so I just set the binding path in the ui builder

but my script does the binding part

[gloomy chasm]

Okay, that doesn't matter, the important part is setting the correct path (either in the UXML or in C#). And calling the .Bind() method on a ancestor of the label.

[wanton arrow]

im gonna try it again once i fix the existing errors

[gloomy chasm]

Okay, and just as an fyi, I can guaranty that it does work as I have done it multiple times before 🙂

[wanton arrow]

god damn what am I doing wrong

even this

[gloomy chasm]

change binding path to m_Name

[wanton arrow]

ah

how am I supposed to find that out

not a rhetorical question is there a place where the actual property names are

[gloomy chasm]

When you have a UnityEngine.Object selected in the inspector, you can right-click the inspector window title and change it to debug mode

[wanton arrow]

rightright

yayyy it worked tyty

[gloomy chasm]

YAY!

[gloomy chasm]

If you use SerializedProeprties here instead, you will get automatic undo/redo support

[wanton arrow]

what if I do EditorGuiLayout.PropertyField

[gloomy chasm]

That works

[wanton arrow]

I changed it to that since I know the actual name

OK this might be a much more niche issue but another thing is when I open my graph I want it to frame the nodes

graphview has a function called frameall

but it doesn't work

it just shows me some random part of my graph I always have to press F to find my nodes

[gloomy chasm]

I would look at the source code for what it is doing when you press F. Will be easier than reimplementing it.

I don't know the answer my self since it has been years since I last touched GraphView

[wanton arrow]

source code?

[gloomy chasm]

If you are using Rider or Visual Studio(I think?), you should be able to ctrl click on the GraphView class to go to the definition.

Or you can view it here https://github.com/Unity-Technologies/UnityCsReference/blob/master/Modules/GraphViewEditor/Views/GraphView.cs

Looks like it just does a FrameAll https://github.com/Unity-Technologies/UnityCsReference/blob/1b4b79be1f4bedfe18965946323fd565702597ac/Modules/GraphViewEditor/Views/GraphView.cs#L841

[wanton arrow]

yeah

I tried a frameall with something else and it works

I assume its bc It still thinks the nodes are all at 0,0

since it just created them

idk what to do abt that

ok looking at the code its using the rects

so maybe I need to refresh the rects somehow?

[gloomy chasm]

Yeah my assumption would be that the nodes have not been laid out yet when you are first calling it.

[wanton arrow]

how would I ensure that

i set the style.top and style.left to move them around

[gloomy chasm]

Could try registering a GeometryChangedEvent, framing all, and then unregistering

[wanton arrow]

uhhh could u break that down slightly

what do u mean register the event

[gloomy chasm]

element.RegisterEvent<GeometryChangedEvent>(OnGeometryChanged);

private void OnGeometryChanged(GeometryChangedEvent evt)
{
  graph.FrameAll();
  element.UnregisterEvent<GeometryChangedEvent>(OnGeometryChanged);
}

Now, where you register that and and what element is... I'm not sure...

[wanton arrow]

ig it would be the graph view

nope

what type is element

[gloomy chasm]

Hmmm... try the graphView content contaienr maybe...?

[wanton arrow]

where r u getting this register event

bc it doesn't work with visual element

doesn't seem to exist

[gloomy chasm]

Ahh right my bad, it is RegisterCallback

[wanton arrow]

oh ok

doesn't seem to work

ill do that later

can you use the uibuilder for the inspector? and if so how

bc I want to have stuff like rounded edges but idk how to do that with standard stuff

[wanton arrow]

ok Im gonna use the visual element stuff

[wanton arrow]

how would I bind something like a list?

I want to update a display of a list whenever an element in that list changes

[barren moat]

Does anyone have a clever way of changing the type of a serialized scriptable object?

I have many SOs of a type exposed by a library, and I'd love to change them into a subclass in my assembly.

I guess the simplest way would be to just modify the YAML directly with a find and replace.

But if it's possible by SerializedObject that might be a nicer pattern.

[wanton arrow]

anybody know that this means

it pops up when I select a selector in the uss uibuilder

[barren moat]

Looks like a bug in UIElements

The stack doesn't go into your code at all

btw you can copy an error's text with ctrl+c

for posting on discord

[wanton arrow]

yeah ig but

what do I do about it 💀

im gonna do a slick reset

[barren moat]

Could try clearing your layout and recreating it

maybe it's in a bad state

[wanton arrow]

restarting the editor seemed to do it

now I need to figure out how to get an element to fill the entire height of the element

im arranging stuff horizontally but one of the elements wont cooperate I just want it to fill the space

changing the top and bottom did nothing and so did anything else I could think of

[barren moat]

You should ask in #🧰┃ui-toolkit

but it's flex-grow I believ

[wanton arrow]

nah

that only works when its vertical

[barren moat]

height: 100%

[wanton arrow]

oh righttttt that should do it

emphasis on should

[barren moat]

top/bottom only matter in absolute positioning

not in flex layout

[wanton arrow]

yep

tysm

works

how would I make this refresh the displayed list when the list property is changed?

this doesn't seem to work

im assuming bc the value isn't changing

just the array

oh ok

I just needed to do track serialized object value

[vestal jasper]

im trying to make a custom editor for a script but i get this error Argument 1: cannot convert from 'UnityEditor.SerializedProperty' to 'UnityEngine.Mesh'
this is my code: https://sourceb.in/xAUVpllZAa

[solid yarrow]

Costin have you tried unserializing the data or something?

[vestal jasper]

i dont think so

[visual stag]

A serialised property isn't a mesh, so I don't know what you're expecting?
Use its objectReferenceValue property and cast it to Mesh

[open sparrow]

Hi guys, I have a question regarding override the mesh assets. I know when Unity imports a model file (.fbx, .obj and etc), the model importer generates a mesh asset linked to it.
I want to write a tool that modifies the vertex color and UVs of the mesh asset. Instead of creating and saving a new mesh asset, is it possible for me to find and load the mesh asset associated with the original model file, modify it, and save it back (or refresh my modification), so that no extra file is generated? And I can just drag and drop the original imported mesh asset to use my modifications?

More specifically, how can I get the path to the dependent mesh asset generated by Unity (in the AssetDatabase persumably) ? And is it possible for me to modify and save this asset?

[surreal delta]

why dont you just use probuilder?

[warm ember]

I don't know if I have to post this question on this channel so if not say to me where I have to put it.

I'm creating an UI using canvas and trying to make it responsive. I have made it responsive regarding to position but know I want to know how to make it responsive regarding to size for my text font size as I set it to auto but it depends on the amount of text I put in the component but I want the text to be proportional with the size in the editor.

[open sparrow]

Cuz I wanna do it via script, and better do not depend on other packages
“Modifying vertex attributes” is just a simplified expression

[lyric dagger]

Hello! I was hoping to get help with programming a EditorWindow. I want it to debug.log some info when the button gets pressed but nothing pops up. Is there a way to debug.log without pressing the play button in unity?
This tool is for developing so it would be used primarly while not playing the game.

[real spindle]

Show your code, what did you try?

Debug.Log on a button press is trivial

[lyric dagger]

was trying to do something like this

this function gets called on a button press in the editorwindow

[real spindle]

What happens when you press the button?

You should see at least something in the console

[lyric dagger]

No messages pop up in console. i was hoping to get some message up both to see that something was added, as well as getting data cause another function I am working on is not working and I am trying to figure out why through debug logs.

this is my console after hitting the add sound button

[real spindle]

Just to check, you dont have errors or logs hidden in the console right?

Top right

[lyric dagger]

no i have them all enabled and it still didnt pop up

I know the button works cause it updates the script it needs to update

its just the debug.log not working

[real spindle]

Hmm.. put a log just before you call stringSetup, and another one inside addSubtitle before the if statement

Just a sanity check. Because from what I see it should work

[lyric dagger]

Omg i didnt realize there was a clear on build/clear on recompile

[real spindle]

Oh, yep lol

[lyric dagger]

Ty for the help. Thanks for being patient with my stupidity lmfao

[regal hill]

Hello, I have the "Reload Domain stuck" problem (again), generally, I close the Unity editor then reopen it, but here, I have some changes in my Scene that I need to save, if there a way even if the editor is frozen ?
pretty please

[whole steppe]

You may ask in unity-talk since it's the most active channel and you are in emergency. Do not mention that to them tho, just ask and they will help.

[whole steppe]

But as far as i know, there is no way to get rid of that. I didn't tried if closing that task from task manager works. But you should try fixing the freezing problem first. But how? You should look at your Editor/ExecuteInEditMode scripts/MonoBehaviours and optimize them.

[regal hill]

thanks

[wanton monolith]

Anyone knows if there's an easy way to have left sidle toggles in UI Toolkit?

visualInput.Insert(checkmarkIndex + 1, m_Label); this doesn't give much confidence

[gloomy chasm]

Set the "text" property to show the text that appears on the right of the toggle, and set "label" for text that appears on the left of the toggle.

[wanton monolith]

you have got to be kidding me, lol tyvm!

[median lance]

How to stretch TextField?

[surreal delta]

wdym, stretch?

[median lance]

Fill the empty space

@surreal delta

[surreal delta]

decrease the field width

[alpine bolt]

Are you using IMGUI or UIToolkit?

[median lance]

Built in editor tools. GUILayout etc.

[gloomy chasm]

https://docs.unity3d.com/ScriptReference/EditorGUIUtility-labelWidth.html

[peak bloom]

https://github.com/ValveSoftware/steam-audio

they oss it now

time to make a fancy linear audio editor for unity ig

it has built-in Unity support already, so incase anybody interested

the docs for Unity specifics https://github.com/ValveSoftware/steam-audio/blob/master/unity/doc/guide.rst

[dawn root]

Is it possible to draw charts in unity editor(with hover tooltips, click action, scroll zoom, axis labels,scaling)?

I can whip one up with in game UI but I just need it for editor tools. Are any of the above stuff impossible to do in an Editor Window?

[lethal imp]

Where did you store the ID ?

[gloomy chasm]

Possible? Yes. Built-in? No.

I mean, it is basically what the AnimationCurve window is

[tough cairn]

any ideas how pagefile is related to this ?

won't let me profile local machine or remotely connected machine ( my current ram usage is at 50% total ram is 64gb )

[visual stag]

How's the page file related to you running out of memory?

It's literally an extended part of your memory only used when you're running out of it completely, that's how it's related

[real spindle]

Handles.DrawLine etc. can also be used in GUI

[visual stag]

It's much easier and more flexible to use UI Toolkit's painter2D vector drawing

See Introducing the Vector API pinned to #🧰┃ui-toolkit

[dawn root]

Haven't dabbled with UI toolkit but this looks promising. Does it allow hovering/clocking on lines/ objects drawn with it?

[visual stag]

Clicking on lines has to be calculated manually. It's the same backend that all Unity's graph tools use, Shader Graph, VFX Graph. So if you see something in one of those, it's been implemented in UITK

[keen tiger]

Hi, I'm trying to set the "build configuration" setting from the WSA build settings option via code. I seem to be wanting to use Environment.SetEnvironmentVariable, but I can't seem to find what the variable is named for me to reference. Could anyone help me out? Thanks

[indigo condor]

hi everyone... does anyone knows what could me making those buttons margin change?

The change is almost imperceptible in the image but when I widen the window it is quite noticeable

[gloomy chasm]

Can you click on one of the buttons and show the inspector for it like you did in these screenshots?

[indigo condor]

ohh, sure

let me do it

like this?

[gloomy chasm]

its cause you have the width using a %

It is adding 0.875% of the parents width between each button

[indigo condor]

yeah, and how could i make this space from both sides to be constant?

[indigo condor]

and use that % just between buttons

[gloomy chasm]

I assume what you are wanting is 3 evenly sized buttons with a const space between them?

[indigo condor]

right

exactly

[gloomy chasm]

In Flex set Grow to 1, and Basis to 0. Leave Width as auto

[indigo condor]

from buttons inspector?

or from buttons container

[gloomy chasm]

Do it per button

[indigo condor]

ok, that's done... now, how could i add the 3 const px space between buttons?

[gloomy chasm]

Set the margin on each button. Normally you would do something like .pages-button--left, ``.pages-button--right, .pages-button--middle`. And create a style for each of them, setting the margin.

Adding each class to the respective buttons of course

[indigo condor]

thankss!

[indigo condor]

and just one last thing... do you know if it's possible to delete this kinda blue border that is on all buttons?

[alpine bolt]

    border-left-color: transparent;
    border-right-color: transparent;
    border-top-color: transparent;
    border-bottom-color: transparent;
    border-radius: 0;
    border-width: 0;```

[gloomy chasm]

Set the :hover border width or color

[indigo condor]

it's setted on 0...

[gloomy chasm]

That is the 'unset' value

[indigo condor]

hmm, that's by code... i would like to know an editor response

[alpine bolt]

Same logic

[gloomy chasm]

'unset' values get overridden by styles. The button has a style that sets it.

You can right click on the field label and click the "set" ("set default"? Something like that) context item

Or just change it to something and then change it back.

[alpine bolt]

you can open this file and set the code if in doubt

Make sure you save UI Builder before you manually set the code manually. Just in case.

[indigo condor]

i'll try both ways :>

even they are the same hehe

hmm @alpine bolt , there are multiple logs

[alpine bolt]

the red underlines on transparent? Ignore that. IDE probably does not support that syntax but it works anyway

if it bothers you, just replace transparent with rgba(0, 0 , 0 ,0)

[indigo condor]

far away that it still the same...

[alpine bolt]

make sure that you are not setting values in each button itself, instead of the classes

[indigo condor]

i don't think so...

[alpine bolt]

Do you want to make the borders disappear on hover or always?

[indigo condor]

hmm, that border doesn't exactly appear when the mouse is over the button... it appears when its clicked

and that happens with all proyect buttons

[alpine bolt]

What are you trying to do?

[indigo condor]

to avoid that kinda border...

to delete it

[alpine bolt]

Button {
  border-width: 0;
}```
This will remove border from all buttons.

[indigo condor]

its not a normal border...

[indigo condor]

let me score you a video

[alpine bolt]

You mean the focus border?

https://docs.unity3d.com/Manual/UIE-USS-Selectors-Pseudo-Classes.html here you have different selectors just like :hover. I believe you are talking about :focus. You can either style Button:focus or .whatever:focus or just make it not Focusable

[indigo condor]

hmm probably is that

lemme try

[indigo condor]

hmm, where is that option?

[alpine bolt]

Directly in the button

[indigo condor]

ohhh

it was that :>

thankss

[dapper coral]

is there a way to do the alt-p inspector on a game object/prefab from code? as if I clicked on it and pressed alt-p, and ideally without losing the thing I already have an inspector open for

[alpine bolt]

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

[hollow ore]

is there some kind of "notification" element that I can use to display dismissible warning in the custom editor? something like a EditorGUILayout.HelpBox with an "x" close button?

[indigo condor]

How could I do this helpbox to have a height based on the left one? I don't want it to expand itself when more lines are added

did I explain well myself?

[alpine bolt]

You can create your own UIElements HelpBox.

    [UxmlElement]
    public partial class HelpBox : IMGUIContainer
    {
        // etc...

        public HelpBox()
        {
            onGUIHandler = () =>
            {
                EditorGUILayout.HelpBox("This is a help box", MessageType.Info);
            };
            
            // etc...
        }
    }```

[alpine bolt]

Have a parent VisualElement for both boxes. Have the left box expand from its content (and then expanding the parent). Have the right box fill available space

[indigo condor]

whaat? I've crashed

those are both boxes

they are on the Horizontal parent

[alpine bolt]

Looking back at your question, I just am more confused

[indigo condor]

Hmmm, let me try to explain well myself

[alpine bolt]

You want your box to minimize height based on its content?

[indigo condor]

I want right boxhelp to have the same height the left one, but i don't want the left one to expand itself vertically when the right one its bigger (i'm gonna add a slider on the right one)

[indigo condor]

did you understand me? hehe, its too difficult to explain it xD

[alpine bolt]

#grand-parent {
    flex-grow: 0;
    flex-direction: row;
    align-items: flex-start;
}

#parent-1,
#parent-2 {
    width: 50%;
}

#parent-1 {
    justify-content: space-between;
}```
Then I think you have to set `#parent-2` height manually in the UIBuilder or in code

[indigo condor]

and update it every time parent one height changes?

[alpine bolt]

Using RegisterCallback<GeometryChangeEvent>.
If there's a better way, I don't know it

[indigo condor]

i'll try it :>

[indigo condor]

it's too concrete the problem hehe, i suppose it will work like that

[gloomy chasm]

FYI, there is a HelBox VisualElement, it just ain't available in the UIBuilder (for reasons???)

[alpine bolt]

My bad

[gloomy chasm]

All good, for some reason some are not in the UIBuilder, like that and Image and TwoPaneSplitView

[alpine bolt]

I haven't touched either because they're limited.
I have my own version of the HelpBox, much more customizable. There are alot more icon variations to be used, for example.

[gloomy chasm]

Really? Isn't it just the 3?

[indigo condor]

talking about icons, is there any easy way to add a rubbish bean icon in this button? (i want it to look good)

or i have to download an image and just add it...?

[gloomy chasm]

I would download one, but you can use an existing one, but only via uss.

Fine, 3 icons types, 2 size

[indigo condor]

thanks! 👍

[indigo condor]

hey @gloomy chasm, is there any way of adding this message using UI toolkit? That one i added it using IMGUI...

Sorry to ping you 🙏

[gloomy chasm]

Gotta do it in the UXML file, not through the UIBuilder sadly, but yeah. Just <ue:HelpBox/>

[indigo condor]

Thankss, what i would do without you and Taunting :>

[indigo condor]

hmm it prints an error

and doesn't work

[gloomy chasm]

Looks like it should be uie

[indigo condor]

it appears kinda weird xD

[gloomy chasm]

What version of Unity are you in?

[indigo condor]

2022.3.9f1

[gloomy chasm]

Should be there...

[indigo condor]

does it works for you?

hmm, i'll try to restart the project, idk

[queen wharf]

Whats the general practice with dealing with data you want saved in various editorwindows without it resetting on closing the window and assembly reloads? Static variables are chill for surviving windows but not assembly reloads and from what im reading to serialise values i need non static variables

Should I just have a ScriptableSingleton per window?

I don’t know if theres a right way to do this just curious on what people think

[peak bloom]

nothing wrong with ScriptableSingleton, imo if the scale of the project is too big, I'd just serialize them manually

[bright phoenix]

I wanna do the following: right click some game object in edit mode and click something in the menu, then after entering play mode, I need to identify the object that was clicked. Any idea how to achieve that in a non-intrusive way (that is, it needs to be single Unity session only, and not generate any changes that will be saved on disk).

[indigo condor]

how could i disable horizontal slider and let just vertical one?

[tender olive]

I would use an editor script to add a component to your GameObject. That component can, at runtime, log its name or whatever you need it to do to let you know which one it is. Then your editor script can listen to https://docs.unity3d.com/ScriptReference/EditorApplication-playModeStateChanged.html. When play mode is exited, it removes all instances of that component - so no changes on disk.

You could potentially try to use the instance ID and cache it in PlayerPrefs or something but I'm not sure if those IDs are shared between edit and play mode.
