tbh I have no idea how Addressables works, I haven't investigated it yet
#↕️┃editor-extensions
severe python
if you want a system to automatically load UXML for a window absed upon a naming shcme the solution is simple
Make a base class with the necessary data you need to automatically load stuff based upon whatever metric you want
using System;
using UnityEngine;
using UnityEngine.UIElements;
public abstract class AutoTemplate : VisualElement
{
public AutoTemplate()
{
RegisterCallback<AttachToPanelEvent>(LoadTemplate);
}
private void LoadTemplate(AttachToPanelEvent evt)
{
Resources.Load<VisualTreeAsset>($"{GetType().Name}.uxml").CloneTree(this);
}
}
just create a resources folder in an Editor path somewhere to store all your templates
this code may not specifically work
dim walrus
I suppose where the name is you also need the path
severe python
generally, hence why I mention using Resources
dim walrus
I like the idea of the base class, gonna look at addressable to avoid path or a common folder
severe python
heh, made this as an example for you, and I'm probably going to end up using it tonight
please let me know what you figure out with Addressables, if there is a way to make the pathing situation better, than that's awesome
severe python
If addressables can be used in the editor, then it seems like it will provide a huge amount of capability for this goal
waxen sandal
IIRC it will
severe python
the WYSIWYG UI editor is coming out with the next major version right?
dim walrus
You can always use the UI Builder
severe python
the what? Do you mean the UI Elements Builder they just announced?
oh well heck, I didn't realize It was available
Can't seem to load a USS file for a given control however
Nevermind, you can if you follow their naming scheme
dim walrus
With that and an auto editor load, making editors could be really easy
Although i'm not a big fan of linking logic with buttons using their names
severe python
?
There is a distinct lack of Code behind support or connecting the UI to logic
right now that connection appears to be 100% driven by code
dim walrus
I'd prefer having a public UIElementReference or something like that
So you can bind whatever you need to it
Rather than having to use a Query to find anything
That's what at least i've seen
No idea if there is other way of doing it

Anyone figured out how to make TextMeshPro.Buttons react to anything other than the main button on a controller or like "right click"?
Do I have to build my own script completely or is it possible to use the built in features to add another interaction button?
severe python
Welp, I made a generator for VisualElements for all the Unity.Mathematics types...
lets see if they actually work
severe python
Okay, so this works pretty well, but there are some problems
First, I can't see how to instantiate a Template element and an Instance element from code, I'd guess its not possible and they expect you to use VisualTreeAssets, this makes things a ltitle wierd
the UIBuilder helps with this problem a bit, since all you really have to do is create a custom inspector class which loads a visual tree for the inspected type, and as long as the XML there is implemented correctly all the binding path stuff works
However, I don't see how you could render lists using this setup
Okay, so this works pretty well, it requires some annoying boiler plate, maybe there is a way around that.
All I have to do to setup a custom UXML driven inspect for a type, for example:
public class TestType : MonoBehaviour { public float3 Test3; public float3x3 Test3x3; }
Is instantiate this class
[CustomEditor(typeof(TestType))]
public class TestTypeEditor : AutoTemplate<TestType> { }
Create this UXML
<ui:UXML xmlns:ui="UnityEngine.UIElements" xmlns:uie="UnityEditor.UIElements">
<ui:Template name="Double3" src="Double/Double3.uxml" />
<ui:Template name="Double3x3" src="Double/Double3x3.uxml" />
<ui:VisualElement>
<Style src="TestType.uss" />
<ui:Instance template="Double3" binding-path="Test3" />
<ui:Instance template="Double3x3" binding-path="Test3x3" />
</ui:VisualElement>
</ui:UXML>
This is enabled by this class, plus generated fields/templates for the Unity.Mathematics types:
public abstract class AutoTemplate<T> : Editor
{
public override VisualElement CreateInspectorGUI() => Resources.Load<VisualTreeAsset>($"{typeof(T).Name}").Instantiate();
}
If anyone is interest in the generator code I'll toss it up on Github
The serialization bindings just work in this case
Using the UI Builder is really helpful for creating the inspector element UXML, because it handles the pathing to the template files
meh, for anyone interested in the templates, https://gist.github.com/PassivePicasso/40ec4db990ef9d106ad349b08e82f9e2
the generator deals with setting up the binding paths as well
that all creates this
onyx harness
We should really consider again creating a channel specifically for UI Element X)

@hearty cypress I'm not sure, I don't have time to investigate more, but look at the internal class PresetLibraryEditor<ColorPresetLibrary>
hearty cypress
@onyx harness ok thanks for pointing me in the direction.
onyx harness
It seems you can find the presets in a file. I don't know where
hearty cypress
I just found the source code on their github. It looks like I can recreate this menu and customize it from there.
which is great because I wanted to do a custom color palette
brisk isle
is there a way to run code in the editor whenever I place a specific prefab in my scene?
onyx harness
@brisk isle EditorApplication.hierarchyWindowChanged?
hearty cypress
@onyx harness is that a poring 😮
onyx harness
I am working on Unity 2017.4...
brisk isle
2019.2
onyx harness
@hearty cypress Hell yeah X)
hearty cypress
sammmee hahaaa!
onyx harness
EditorApplication.hierarchyChanged?
brisk isle
yeah that seems like one that could work thanks
just to make sure I'm not on an XY problem
what I'm trying to do is, whenever I place an object on the scene in the editor, i want to check if theres another object, exactly Vector3(1,0,0) away from it
onyx harness
It's a way to do it I guess
brisk isle
@onyx harness thanks
whole steppe
Am having problem
With buttoms
If i press one of them it will only press the first buttom i created
Any thoughts?
onyx harness
Any code?
whole steppe
@onyx harness i am only using Canves
I have an Invetor y
Inventory when i press lets say The armor place it will press On the helmet place
Same as everything else it will always press on helmet
i think its a layers thing?
Oh fixed it
its all good ❤
hearty cypress
how do I set a white border around an ongui button?
onyx harness
@whole steppe you are on the wrong channel.
@hearty cypress you get the position of your button and you draw 4 lines around it.
hearty cypress
@onyx harness could I use DrawTexture for this? Im thinking a black 2x2 pixel that is expanded via ScaleMode.StretchToFill. Or is there a Draw Line method I didnt see?
oh nevermind i found it DrawLine.DrawLine(pointA, pointB, color, width);
onyx harness
I'm not on my computer, but yeah there is utilities for that
They are not optimised, but they do the job
hearty cypress
maybe a 2x2 white pixel texture stretch and put behind a button is more efficient than drawing 4 lines
hearty cypress
Not sure why but the color doesnt change when I click a button:
Texture2D selectedColor = new Texture2D(2, 2);
changeSelectedColor(selectedColor, Color.white); // set to default color
if (GUI.Button(redButton, ""))
{
changeSelectedColor(selectedColor, Color.red);
}
if (GUI.Button(blueButton, ""))
{
changeSelectedColor(selectedColor, Color.blue);
}
my helper function looks like this:
private void changeSelectedColor(Texture2D selected, Color c)
{
for (int y = 0; y < selected.height; y++)
{
for (int x = 0; x < selected.width; x++)
{
selected.SetPixel(x, y, c);
}
}
selected.Apply();
}
this is OnInspectorGUI though.
onyx harness
What do I need to conclude with it?
hearty cypress
Doesnt OnInspectorGUI draws on event changes for inspector like EndChangeCheck(). So i dont see how it is every frame.
onyx harness
Everytime you draw your buttons, just before you created a new texture white
When you click you modify the texture
But the next frame will have again a new texture created
It's always white, that's what I trying to say
hearty cypress
yeah i guess im not understanding the order of render here. id assume if clicked once itll re-render just once.
hearty cypress
like cache or store as a serializable or something?
onyx harness
Just a field
If null, you create it
Or in a OnEnable
Whatever suits you, as long as it is done once
hearty cypress
Okay this is clear for me to resolve it, thanks.
got it. thanks @onyx harness. Heres my ghetto palette selector.
onyx harness
Haha gj
severe python
@onyx harness I apologize if my large comments were annoying or something
severe python
I did go an put a suggestion into the server feedback channel about creating a separate channel for ui elements, especially considering it will be getting runtime compatibility in the next year
onyx harness
@severe python oh no, don't worry, but it was a suggestion made a long time ago
severe python
with unite 2020 copenhagen showing that UIElements is going to be an important technology going forward, I think its more necessary than ever
having a good place on here where people can work out some issues with the technology so it can be improved I think would be helpful for both users and unity tech.
On that note, maybe you (or anyone else here) have some thoughts on an issue I'm running into with this stuff I'm setting up
I'm trying to implement a few basic controls that would really ease the usage of UXML by enabling binding-paths to be used more easily, thats what those big posts up above were about
now I'm trying to setup a ListView, I originally started by trying to implement listview, which successfully bound to the binding-path, but its implementation doesn't allow for elements of multiple types, so I'm trying to build a new list view from scratch
but even upon reviewing the binding system in Unity CS, I can't really tell how you'd utilize bindings in a custom VisualElement
it seems like maybe you can't
onyx harness
I am very far from being an expert on UI Element unfortunately
But I hope to become one, one day! 😁
I just know the theory, never practice yet
severe python
I may know more than most and thats kinda frustrating
I've combed over a fairly large portion of the Unity CS reference with regards to UIElements, multiple times since it was first introduced
onyx harness
So... Is it good?
severe python
If you look simply at the UI creation aspect, styling and structure are super easy
and very powerful, makes it really easy to make something well layed out and nice looking
comperable to HTML
In simpler situations for Serialized objects, where you don't have lots of nesting or arrays/lists of base types which contain multiple sub-types, the bindsing is very easy to setup and works really well
however, when you're trying to go just a little bit more advanced things get hairy
because they hide a bunch of the systems that, atleast at a glance, you need in order to work with bindings
severe python
which honestly, is probably just a lack of understanding on my part, but it shows a weakness in either the design or the documentation
crystal timber
😂
severe python
?
crystal timber
I'm worried if I asked too many questions about UIElements here... maybe it's really nice if there's a separate channel
onyx harness
Just shoot, there is almost no contraint about asking questions
severe python
how would you figure out if a binding is taking place...
visual stag
The fact that it says inspectors call Bind itself is confusing
especially when you're not working with the scriptable object the inspector is operating on
I totally agree with the:
because they hide a bunch of the systems that, atleast at a glance, you need in order to work with bindings
which honestly, is probably just a lack of understanding on my part, but it shows a weakness in either the design or the documentation
which is completely my experience with it
severe python
oh man, the more i look into their binding system, the more disappointed I am...
I'm just going to pretend it has to do with the fact that its a game engine and all this spaghetti is necessary for performance...
yeah
it really makes me think I just should just do my own thing
severe python
buahahahhaa, I got this auto-binding auto templating inspector crap working I think
ArchetypeManager contains an array of EntityModel, which I showed up above a bit. The EntityModel contains IDataComponents which are populated with different IDataComponents, and then Ihave a class, ItemsControl which derives from Bindableelemetn which looks up a UXML file based upon the type name found in the array element
so now I can easily render complex arrays, and fill in missing elements by simply creating a UXML file
low crown
Would it be possible to create a slider where one end would gradually change to warmer colors and the other would change to colder colors on a game object? (Oddly specific yes but if anyone could lead me to a tutorial that’d be great)
onyx harness
@low crown Slider is just a value between 0 & 1
From that value, you do whatever you want
severe python
I gotta say, once you get something setup to do good automatic loading of UXML its pretty great
I've been just building views for the past couple hours
and haven't needed to touch code
Honestly, this is how it should work out of the box
severe python
exactly
onyx harness
That's a HUGE time saver
severe python
rapid iteration is huge for UI/UX
its the difference between a good ui and a bad one honestly
this has been a great workflow
Once I got that list control working, I've been able to just build UXML templates for various IComponentData implementations
and as you can see, they are quite simple
sleek edge
Hey, I want to do something that's probably a bit too ambitious
In order to add effects (aka functions) to a scriptable objects, I decided to do this: create a bunch of templates for functions with variables (deal damage, move something somewhere, heal, play, return to hand, etc...) that I could then drag n drop inside of a List or array and that would display input sapce where I would be able to enter the variables, like with a MonoBehaviour script component.
TL; DR If I could put a MonoBehaviour-extended class inside of a List in a way that allowed me to modify the variables just like in a component, that would solve my problem
If you know or have ideas on how to make this possible, please ping me. I'm quite new to modifying the Editor
onyx harness
I'm so not used to the new UI. Still working with U2017, I cant wait to switch ! 😄
Hum... what is UI Builder? native editor?
severe python
its an editor for building UIElements
its good with a little glue like I've built, but its still buggy
like, buggy to the point where, its important that I don't create UXML files before I open the UI Builder, the file needs to not exist and I have to start a new one INSIDE the UIBuilder in order for anything to save
and for data to actually flow into the UXML, I hae to add an element, then cut it, then paste it, and then the template will correctly start updating
low crown
{
foreach (GameObject obj in Selection.gameObjects)
{
obj.GetComponent<SpriteRenderer>();
scale = EditorGUILayout.Slider(scale, 0, 100);
}
}``` I'm trying to make my scale affect my gameobjects color, any tipslike one would be on the cool spectrum and the other on the warm
I think I have to make a color array
sleek edge
I think the error comes from the fact you aren't actually storing the sprite renderer anywhere
You are calling it, but it's not going anywhere, no variable
Try adding SpriteRenderer renderer = obj.GetComponent<SpriteRenderer>(); instead
Then you'll be able to modify the different values of it
Don't know if that's the issue you are encountering but that's the first thing I noticed '^^
feral karma
@severe python would be great if you can report bugs about those. I had similar experiences but sounds like you might already have clear paths for reproduction
crystal timber
Is there a way to force a newly created VisualElement re-layout or get informed after VisualElement resized? I want to do some positioning according to Node sizes in a GraphView...
visual stag
a GeometryChangedEvent could be one way of doing it
crystal timber
thanks!
severe python
is there a forum for the UI Builder somewhere?
I need to solve one more problem, which is how to deal with adding to and removing from arrays and allowing different controls to do that
severe python
Hmm, how would you find the current editor object from within a visual element that
severe python
Yes, I finally figured out the design for this templating setup, and I couldn't be happier
severe python
I swear I'm the only person who gets excited about good ui frameworks
feral karma
you're not! following closely here ;)
Have you figured out a good way to draw a auto-resizing table? Unity themselves create it using vertical columns but it's super hacky to get the rows the same height then
@severe python
severe python
I have done nothing with tables
what do you mean auto-resizing?
you talking like an excel grid?
severe python
unfortunately I've seem to have come upon a bug in unity thats causing it to crash
severe python
looks like an issue with looking at an array element which doesn't have a value assigned to it maybe
severe python
Welp, I'm quite happy with where I've gotten to
the performance of generating the interface is a bit slow, which I'll have to investigate, but the interaction performance is great
There are some places where I'm collecting and iterating over every type in the current app domain, so that could be part of it
severe python
hmmm, how do you increase the size of an array of structs with SerializedProperty without duplicating the values from the previous element?
I don't see a way I can' assign a struct to a SerializedProperty
severe python
Popup stuff is a really weak thing in this system
unless you feel like adding a style to the root of your inspector...
severe python
popups are murder 😦
severe python
oh man, so it turns out an auto-suggest box of this nature is not possible
severe python
there doesn't appear to be a way to position a popup window in uielements without it being a imgui popup
candid briar
@gloomy chasm Don't know if you were still wondering about making your UI scale with screen size but HandleUtility.GetHandleSize() might work.
brittle cosmos
Is it possible to allow dropping one or more items from the project or hierarchy into a ReorderableList like you can with the default array inspector?
waxen sandal
Sure you gotta implement drag/drop yourself
candid briar
Which you can do by making using of Unity's event system 🙂
brittle cosmos
Oh ok thanks
brittle cosmos
Cool that was pretty easy
patent seal
is there something that can set textures to materials programmatically in editor? I have this mesh with like 100 child objects that I need to set textures for
gloomy chasm
@candid briar Thanks, I ended up realizing I was saying the opposite of what I meant. I wanted the handle to stay the same size. So when scrolling out it would be smaller, like gizmos. But don't think it is possible.
@patent seal yeah, though if they all just need the same texture you can just select them all and drag the same texture on to them.
candid briar
For staying the same size:
Ye you can use sceneView.cameraDistance. Unless you mean something else?
patent seal
@gloomy chasm they all need a different texture
the tex names are like 001, 002, 003
onyx harness
@patent seal yes you can
severe python
@patent seal the Mesh component has a submesh value, each face that needs a specific material needs to be a different submesh, once you have that then you can assign a number of materials to the MeshRenderer's Material array
the index of the material array corresponds to the submesh
patent seal
yeah my question is how do I do that with a script
instead of manually dragging
I load the texture I want via AssetDatabase then assign it to my meshRenderer, how do I save it
severe python
Just to check, are you just working with GameObjects and MonoBehaviours?
patent seal
yes. I found out I can create a menu button that creates materials via AssetDatabase.
I make a material per texture that I want.
Now I have a game object in my scene with 100 children. I need to assign each children the corresponding material taht I have in my asset folder
severe python
wiat, are the 100 children, all game objects? or are you talking about a mesh with abuncha different sub meshes?
severe python
so ignore what I said above, its not correct for your scenario
okay, so you'll need to iterate over each child game object, which you can do via Transform, and then get the MeshRenderer on each child, then assign the Material to its material property
severe python
if you want to save it in the editor, you'll have to write that into an editor script, but the same thing applies
if you want all the frills, then you'll do it via serialized properties
So iterate over the gameobjects children, get the MeshRenderer, then do a new SerializedObject(MeshRendererInstance), then
serializedObject.FindProperty("material")
then I think you'll assign the material to, materialProperty.objectReferenceValue
if you've not worked with editors before, then you'll want to read up on it, its a bit more than I can just describe quickly here without probably screwing something up
patent seal
Interestly, might be a new thing, but I just changed the object via the editor script without having to explicitly save, and it worked
public void AssignMaterial()
{
MeshRenderer[] frames = rootMesh.GetComponentsInChildren<MeshRenderer>();
for(int i = 0; i < frames.Length; i++)
{
var name = destination + i + ".mat";
Material material = (Material)AssetDatabase.LoadAssetAtPath(name, typeof(Material));
frames[i].material = material;
Debug.Log("Assigned " + name + " to " + frames[i].name);
}
}
that will generally work, but you'll miss out on some things which I'm incapable of clarifying
Undo won't exist, so if that matters you'll want to setup support for it, its not too hard for a 1 off case
patent seal
yeah that makes sense. Thanks for your help 🙂
severe python
no problem
gloomy chasm
I can't figure out how the heck to do a Singleton MonoBehaviour that works in editor. Any ideas?
cedar reef
Does it have to be a MonoBehaviour for some reason?
Because it can just be a static class at that point
gloomy chasm
I need it to save the data from designtime and use it in runtime.
cedar reef
You could save it in a ScriptableObject
gloomy chasm
True
cedar reef
If you really have to use a MonoBehaviour, you can force the editor to load a prefab into memory with PrefabUtility.InstantiatePrefab and work with it from there
But you'll need a static class to do at least that
severe python
I want to metnio, I've frequently run into problems when I've tried to use static initialization in unity
I do a lot of heavily dynamic reflection stuff though, so that could be related
gloomy chasm
No, a So should work better actually. Idk why I didn't think of it, I have been doing so much with SOs of late...
Can you use ISerializationCallbackReceiver with SOs? Or do you need to? I need dictionaries.
cedar reef
You can
severe python
sorry, I believe you can, whether or not you need to I'm unsure, dictionaries are dictionaries
cedar reef
You can use ISerializationCallbackReceiver with any class marked with the Serializable attribute
There are assets that bring dictionaries to the editor, a few of them free
gloomy chasm
Yeah, I only need the serialization. As long as they are saved, I'm good. And I can just put the keys and values in arrays for that
Shoot, now I gotta remember how to get things to show in the sceneview from a SO
onyx harness
I work a lot with statics, there are some stuff required to know, but beside that, it works like a charm in the Editor
cedar reef
Yeah, just gotta be aware that everything basically gets cleared out when there's a recompile
odd vessel
I created a custom editor that draws a handle in OnSceneGUI with Handles.PositionHandle, and I'm also using a Vector field in OnInspectrGUI.
However, when moving the position handle, the vector field doesn't update. how can I force refresh of it?
lucid hedge
@severe python is that UI Builder something native? or your tool?
waxen sandal
There's a new UI Builder in 2019.3? IIRC
onyx harness
I'm no expert on this matter, but is it possible to use UI Builder in 2019.3 then backport the result to an earlier version?
onyx harness
That would be great, but still asking, because... I don't expect it to work
lucid hedge
can UI Elements be used to create UI in scene view?
should be right?
just not game view right now?
onyx harness
I don't know how different are the engines between versions
waxen sandal
@lucid hedge You should be able to get the root object of the scene somehow not sure if it's officially exposed
lucid hedge
cool thanks
severe python
It's a custom ui elelements, some ui buildera
severe python
honestly, UI builders part is fairly limited
oh, nevermind thats not what you were asking lol
@waxen sandal @lucid hedge UIElements for the scene/game are not available just yet, but soon
waxen sandal
Well you can draw on top of the scene editor window
In hacky ways
But not for actual ingame use
lucid hedge
Yeah that's what I want just scene editor. Just edit mode.
But overlayed on scene editor.
Scene view*
severe python
is probably possible, but I don't actually know
lucid hedge
I think it should be, will give it a try

Is there a way to add class instances into propety via inspector? I have a component that can accept several "strategies", and I want to just select a type in inspector (inheritor of a specific abstract class), and have it instantiated in runtime. Also I want to set its properties in inspector. Same for an array of strategies. (may be kinda Volume Overrides, or something).
severe python
not without making a custom editor
and what you're trying to do isn't exactly clear
are these class instances derived from MonoBehaviour or ScriptableObject?
tidal cave
I don't need them to be even Object, but if it is required, I can make them anything or [Serializable]
It's more like a logic plugin, e.g. if I have an actor (gameobject with behavior), I'd like to plug in different decision making strategies, etc.
Like for AI, it could be "reaction to alert" and strategies like "attack", "flee", "defend"
severe python
this has always been a little difficult because unity serialization couldn't handle multiple types in a field or an array
You can populate a single field with a specific type, if you build a custom editor, but you'll lose the data type upon serialization
That being said SerializeReference is a new feature aimed to solve that problem
but you have to be on the 2019.3 beta to try it out, and its still buggy
severe python
thats what I'm using to do all that component stuff above, I have a struct with IComponentData and ISharedcomponentData in it, and I built a custom editor to allow me to populate them
basically I get a collection of all types that are assignable to IComponentData, and created a search box that lets me pick one, create an instance, and inject it into the array
tidal cave
Dang, too complex. I was hoping for something easier 🙂 For now I just have a number of empty GO with strategies as components on them, and I set a component property from there…
severe python
its not too bad tbh
if you're dealing with a single field, you're talking a few lines of code, maybe 20?
tidal cave
I have fields and arrays. Thanks, I will look into SerializeReference and *ComponentData stuff.
severe python
void OnInspectorGUI()
{
var types = AppDomain.Current.GetAssemblies().SelectMany(asm => asm.GetTypes()).Where(typeof(IComponentData).IsAssignableFrom).toArray();
var property = new SerializedObject(target).FindProperty("IComponentDataField");
//GUI stuff to present type options
//GUI stuff to select type option
property.managedReferenceValue = Activator.CreateInstance(selectedType);
//Importantly
property.serializedObject.ApplyModifiedProperties();
}
with an array you'd have to use the property.GetArrayElementAtIndex call to get the actual property element
that said nothing says you have to use serializedProperties, they just provide some additional functionaltiy over modifying target directly
tidal cave
Does reflection work in il2cpp targets? stupid me, it's editor
severe python
tbh, I donno, but yeah, doesn't matter
I think some reflection works
I believe its just System.Reflection.Emit that you can't use
fresh shell
Is it possible to add to the window context menus? such as when you right click on the inspector window, I want to put something in the add Tab section but I cant seem to find the right context for the MenuItem attribute.
severe python
I knjow you can fo rmany places, though I'm not sure about that one specifically
@fresh shell This is how they get the ui elements debugger in there I think?
public const string k_WindowPath = "Window/Analysis/UIElements Debugger";
Oh awesome okay. Thanks @severe python that should be a good place for me to dive more into it.
severe python
I just was looking aroun the unity reference
which I totally recommend keeping a copy of on hand, because its helpful for this kinda stuff
fresh shell
That's a good idea
severe python
I found that just by right clicking on the tab seciton you were talking about, thens earching for UIElements Debugger
onyx harness
@fresh shell have you looked at IHasMenuItem or something similar, I don't remember the exact name
severe python
in the source code, to see if I could figure out the path
fresh shell
@onyx harness I hadn't I'll take a look at that too. Thank you!
onyx harness
This one allows you to intercept the contextual menu when you right click the tab of a window
severe python
man, no one from unity responded to my popup positioning issue
onyx harness
Positioning issue? What is it?
severe python
as far as I can tell, with UIElements you can't get the screen space position of a control
Since UIElements are drawn in hierarchical order, you have to move a control up to the rootVisualElement as the last child in order for it to render above everything else, within the window panel
however, if the popup would show up at the edges of the panel, it would be cut off, or you have to have some code to have it move its positioning so it remains visible, which may not be preferrable
So the obvious choice would be to launch an EditorWindow with EditorWindow.ShowAsDropDown or Editor.ShowPopup
however in order to use either of those you need to be able to position them with screen space coordinates
and since you can't find the screenspace coordinates of a UI element you cant position them appropriately
And so the only way to actually accomplish this is to setup an IMGUI container and use the old REct layout system
and a classical imgui popup window, which means your popups cannot contain uielements
onyx harness
Interesting, if one day I stumble upon that, I will gladly investigate
severe python
there is a work around with using Win32
but I didn't want to solve it using a platform specific solution
even though it will never affect me, I may decide to release this code for others and in that case I'd like to not prevent it from being usable for linux or macosx users
severe python
welp, i guess we will be getting the ability to control z-index, eventually
it is not a "near term priority"
so 2021 maybe?
:/
severe python
buahahahaha, I stumbled upon a solution that should theoretically be portable
it does use reflection...
welp, I figured out how to handle positioning
but editor windows take focus when shown
onyx harness
What is the problem with reflection
severe python
I'm now in the process of hacking my way to success through reflection...
I'm accessing methods and properties marked internal in the Unity source
severe python
which means its not an API which means it subject to change without notice
onyx harness
The notice is the alpha ;)
severe python
so it could break at any time
fair enough, I could be ahead of everyone except other people like me who live on the bleeding edge
onyx harness
Trust me, this is no issue
severe python
also, what you talking about, just keep the focus?
I don't know a way to not give up focus?
certainly not in this context
onyx harness
Get the current window and focus it right after you opened your popup
Or create your pop-up manually
severe python
well, I did it, I can open the window as a popup and not lose focus
oh I tried that, it didn't work really
onyx harness
(I don't know your code, so I don't know which technique you used)
severe python
I tried a bunch of different things with not giving up focus by refocusing the textbox, none of it actually worked sadly
but now I'm not even losing focus in the first place, which is honestly preferable
severe python
I'm making progress here, but god damn, its just a slog
every problem I solve leads immediately to a new problem
so it works, but I"m having all kinds of little issues
it seems the focus transfer to click on something is an issue
severe python

Just make it persistent. Save it to disk, then delete it.

@severe python is that thing with Add component to Entity Model your editor or something standard? I need exactly this!
waxen sandal
Is it possible to show a tooltip like window when the user clicks a button?
Something that would say for example "Id copied"
visual stag
https://docs.unity3d.com/ScriptReference/EditorWindow.ShowNotification.html might do if you're making an editor window
waxen sandal
Custom Editor :/
visual stag
You could find the inspector in question and send the event there
or implement it yourself, as I did for my preview inspector https://github.com/vertxxyz/NTexturePreview/blob/master/Editor/NTexturePreview.cs#L112
waxen sandal
Oh fuck
I forgot, it's actually neither an EditorWindow or an CustomEditor
It's just a class that gets used in multiple different places
That has a draw method
It mostly gets used in a custom editor though so I'll just show it in there
Thanks!
severe python
its a custom control I built, its a type ahead search box (really just doing some contains checks on strings)
actually its a combination of htem I built for UI Elements
theres AutoTemplate which sets up the whole root of the inspector using a type lookup for the uxml template
and there is the ItemsControl which does the same thing against an array/collection, it looks up each items type and loads a uxml template by name
then there is finally the SearchSuggest control, which is what makes up the parts of the "Add component" ui, which justpresents a list of labels that you can click on in a poup window which populates the items control
an itemscontrol*
severe python
actually it can populate whatever you tell it to
severe python
Anyone know if there is a way to see if Unity is losing focus as a whole?
severe python
nah, i was hoping for something generic
a unity api or something, I can do a whole lot of neat stuff with win32, I just don't want to go down that road
not unless I know of, how to interface with, and target other platforms method of doing so
and I can't even test it
like, one time I put a wpf application inside an inspector for Unity, becuase I hate IMGUI
built a whole ipc mechanism to update the data between unity and the app
was totally more trouble than it was worth
patent pebble
hi! Does anybody know if there is a simple way to create a new handle every frame and keep the handle from the previous frame in it's position?
is that possible at all?
I'm drawing handle sphere like this:
Handles.SphereHandleCap(0, debugger.transform.position, Quaternion.identity, 0.5f, EventType.Repaint);
I would like to redraw that handle every frame but keeping the handle of the previous frame also drawn
cedar reef
You have to store the previous positions, and do a Handle for each of them.
patent pebble
that was my guess, storing positions in an array and drawing multiple handles. But I wanted to make sure if there was a simpler way
thanks anyways @cedar reef 🙂

I know I have learned this before but I have forgotten. Why would the selection for my freemove handle be like twice the size of the handle? And more importantly how do I prevent it?

hi i'm really struggleing with the [SerializeReference] attribute in 2019.3. it does what it's supposed to but it refuses to apply changed fields to the asset if i use a custom inspector for the class that holds the [SerializeReference] field. property drawers don't show up at all and even a normal enum field shows up as an int. this can't be how it's intended to function right? how can i get around this? i need a [SerializeReference] tagged field to work with propertyDrawers and preferably also with custom inspectors...
severe python
Are you using UIElements?
If so, I guess PropertyDrawers don't work for UIElements yet
uncut snow
Did anyone ever serialized a field by its own? since unity doesnt support polymorphism- serialization before 2019.3 ?
waxen sandal
What?
uncut snow
i mean save a inspector field with some other serialization lib and load it ?
severe python
@uncut snow I have a hierarchical class structure I serialized with Newtonsoft.Json because the design relied upon properties which where backed by an object graph and I needed to serialize the graphs behind the properties in addition to the structure
it was a pretty miserable experience overall, and I had constant problems when the data structure changed
however, if you use ISerializationCallbackReceiver https://docs.unity3d.com/ScriptReference/ISerializationCallbackReceiver.html
you can do it
uncut snow
thx for the info^^

I know it's single threaded but come on...
waxen sandal
Some of the newer Unity assets like ShaderGraphs are actually not serialzied with Unity
They use a custom serializer that they save in a normal .asset file
And are then trasnformed to the asset file using a scripted importer
surreal bramble
guys i have variables inside of a class that i use in a list and i need the editor script to show a variable inside of the class instead of in the script in the inspector
stark geyser
You need to make serializable the class you are using, by adding [System.Serializable] on top of it.
Every public or marked with [SerializeField] attribute field inside of it will be serialized in the inspector in Unity
severe python
it does not work for Properties however, only Fields
surreal bramble
public class dialouge
{
public string ElementName;
[TextArea]
public string Text;
public bool skip;
public float skipT;
}```this is my class
i want the skipt to appear only when skip is true
and iam using this class in a list
cedar reef
Then you're going to need to make a custom property drawer
severe python
yeah, you'll want to write a custom PropertyDrawer for the dialogue class that checks the value of skip and then renders skipT based upon that
stark geyser
Unity manual has examples how to use it. https://docs.unity3d.com/ScriptReference/PropertyDrawer.html There are plenty of tutorial for it as well.
cedar reef
You have Google at your fingertips. Don't be afraid to use it.
severe python
Aye, I'm not one to do the "You need to google first" but when it comes to specific implementation things, following the manual or watching a well built tutorial is better than some chat conversation
surreal bramble
i always do google first i just don't know what to specifically look for right now
severe python
No worries, the hardest part of development in my opinion is knowing what to look for
surreal bramble
if i have class f inside of anthor mono class n do i have to say typeof(n.f)
and f is serializable
severe python
do you mean like
public class MyBehaviour: MonoBehavior {
[System.Serializable]
public class dialouge
{
public string ElementName;
[TextArea]
public string Text;
public bool skip;
public float skipT;
}
}
yes
severe python
yeah, the parent class becomes like (this is not TECHNICALLY accurate) a namespace

regal jasper
@surreal bramble check the console for the error description, it is probably warning you that the method should return a VisualElement but you are never doing that
severe python
uh, that might not work, maybe its in specific versions, but I've been told that UIElements PropertyDrawer doesn't work
maybe thats incorrect
or maybe theres a caveat I'm not aware of that causes that situation
severe python
huh, there must be a more specific situation, or I was just misinfomred
surreal bramble
is there something like DrawDefaultInspector (); for property drawers
cedar reef
Yup, that's how you draw a default inspector
If you mean draw the default one, not a custom property drawer, no there's not a method I'm aware of
Possibly something you could do through reflection
surreal bramble
right now it's giving me this error how do i fix it

maybe thats what I was being told
Examine this and the response, it may be releavnt

Unfortunately for you, I don't do a lot with imgui or property drawers, uhm
maybe don't call base.ongui?
I imagine that woudl draw the property twice

lots of room for improvements in thie system, some of the code in ItemsControl can be extracted into its own code for just a template presenter
I should make this a package
severe python

@surreal bramble you need to override GetPropertyHeight()
And in your OnGUI, you are not required to call Begin/EndProperty.

But you'll also get autocompletion of CSS :/
In VSCode you can mark the file as CSS in the bottom right
The ini button

I use Notepad++ for it
it would be nice if they built a syntax engine for VS though
crystal timber
In vscode you can add these to your settings.json
crystal timber
ah without that line
just add uss and uxml, the css editor in vscode is really nice
severe python
I wonder if there is a way to do that for regular VS

das really neat
oh, I guess I could just build a USS text editor with UI elements

in regular VS you can click 'Open with...' on the file and select css/xml editor as default

I'm generating mesh in Editor when user hits a button and assign the sharedMesh in MeshFilter component. When object is in scene it works perfectly. But when I make it a prefab, it generates mesh, everything is working, but when I open scene or another prefab in Editor, the generated mesh is lost… Any ideas?
onyx harness
Your mesh is 100% temporary
If you lose its host (a MeshRendrer I guess), you will lose the Mesh.
You need to save it to disk.
tidal cave
I have a MeshRenderer on the same object…
But I wonder why Scene persists the Mesh (even with Unity closing and reopening) but prefab doesn't
severe python
the issue is the mesh isn't an asset
the data isn't saved into the MeshRenderer
the meshrenderer saves a reference to an asset that is going to disappear
in a scene that asset reference can persist
but outside it has no where to peresist to
IIRC, you need to use AssetDatabase to create an asset for the mesh
tidal cave
Why is it so? Scene and prefab has more or less the same structure, and in scene Mesh is serialized, and in prefab it is not
severe python
I can't say specifically as I don't know
but they are not the same overall
You could view a scene as a prefab
but its not one, they are different
you can't override elements of a scene and store multiple versions of the same scene with overrides
onyx harness
When your generate a Mesh and assign it on a MeshRenderer that lives in a scene, the scene persist it after restarting Unity? O_O
I need to check that
tidal cave
Yes, the mesh data is in the YAML file
onyx harness
Interesting...
Well I guess it is auto-embedded
While a prefab needs a viable link to the Mesh.
severe python
the important part that matters is that it doesn't happen for prefabs
Why that is, ask Unity Technologies
tidal cave
Yeah, I understand that it doesn't happen 🙂 I was thinking I'm missing something
onyx harness
But technically, I would like to add, a scene is a prefab.
There have no difference but the extension at the end.
Which will be handled differently due to it
tidal cave
Can I may be create an empty persistent mesh, link it to prefab, and when generating code would update the original mesh?
tidal cave
May be I'm blind, but I can't see how to create an empty mesh asset…
tidal cave
UnityException: Creating asset at path Prefabs/Small Stone Mesh.asset failed.
No much information in the exception…

Yes, thanks. 🤦

lone wing
I have an editor script that contains some variables, like objects, when in a session I drag the assets into the object fields (some in the scene, some in the project), is there a way to make those persistent after restarts of Unity, or do I need to make a scriptable object or something like that and serialize that? I have them set to [SerializeField], and the editor script set to Serializable, but I guess I am confused on the set dirty part, if that is what I am missing.

Can you make custom editor windows which are based on the scene view?
I'd like to make a comprehensive level editor that's separate from the regular scene view, but still is based on it so I can make use of the built in tile brush features
waxen sandal
@tidal cave Got any gifs?
feral karma
@half marten last time I needed something like this I ended up making hidden/invisible objects in the scene, with a camera that renders them to a separate RT that's used in the editor window
Gives you full control but you have to do all raycasting etc yourself.
Not saying this is the best or only way :)

does that allow tile painting on the custom window though?
i imagine not, since it's just the visual element of the camera render

I has more discovered with reflection, and I confirmed Unity doesn't exposed UIElement bulit-in control's subclasses
severe python
no it doesn't but you don't need to use reflection to look at the unity code base
go grab the Unity CS REference source

I have more discovered, there's TextElement abstract class exists
PopupTextElement inherits it
So I actually now can access without reflection
@severe python and thanks to notice it to me! (but I found it before see it, my spended time...)
@severe python hey can I capture your advice?
Just posting on my devlog
oh god
PopupFieldTextElement

@severe python so can I post your advice?

to grab the unity cs reference?

all I did was point you at something they did
I'd prefer if you didn't put my profile pick/nick in there tbh

If I were writing a devblog, I may say "With the help of a user on Unity's official Discord I found the Unity CS Reference source, an invaluable tool for anyone working with Unity's newest technologies" or something like that, then link the github repository

You're welcome

@odd swan make your window really small then use that popup
does it still work right?
odd swan
yes
Unity's default font is actually hard to read in HiDPI
with CJK text
:(
So I replaced that
CJK stands Chinese, Japanese, Korean
Unity's default font doesn't contain CJK range font, so they replace system default font
...and there's not exist font weight
;(
odd swan
yes i does
defines root style
my problem was
by just this / thing
this separates popup and generic menu list
so I was discovered about this is UIElement, like web development. may can able to only swap it's display text?
Process of my discover
- change
valueproperty - failed, it's throws ArgumentException withNot present in list of possible values - get Label through querySelector(Q) to change it - failed but found it PopupTextElement is private subclass
So I first time search about it but as you know, I was search with wrong keyword lmao (
PopupFieldElement)
Then I check with debugger and inspect what it have fields, properties.
- using ＲＥＦＬＥＣＴＩＯＮ to force set it's value - ok, but hmm this is actually only way to able this?
So I post at here and...
- I found
PopupTextElementis inheritedTextElementabstract class! - And got a Unity source repo to check it's structure.
Even works well with it, yay!
After discover, I realize I was search with wrong keyword
Anyway it's solved!

Hi i got strange results in the scene height values
viewing the numbers like so:
Debug.Log( SceneView.currentDrawingSceneView.position.height + " , " + Screen.height );
OnSceneGUI for a custom editor
1st and 2nd value don't match
more over the difference between the two is never static
also im using scaled DPI on windows10
any ideas ?
Huh ... i think i got it
var diff = Screen.height - SceneView.currentDrawingSceneView.position.height * EditorGUIUtility.pixelsPerPoint;
which will result in a semi constant value of 24.25 ~ 25 ( with a cyclical step size of 0.25 )
very strange
maybe it has to do with my current DPI scaling of 125% which results in the .25 step size
yep... changed to DPI scale size of 150% and now the value is 30 ~ 30.5 with a step size of 0.5 ...
so at scale of 100% the difference will always be equal to 20
maybe it has to do with the scene view header ( where the light, sound, skybox buttons are )
severe python
oh man, yeah Unity wouldn't be DPI aware would it...
tough cairn
old but gold
im trying to align a 2nd helper GUI box like the particle system
looks like magic numbers are the only solution to make it fit
severe python
why not use relative positioning instead of pixel positioning?
is that not a thing in the sceneview?
tough cairn
oh lol i think it is
let me try
huh...
seems to do the trick
but there is a catch
20 pixel bottom padding
although using the relative positioning ( i assume you meant to use the GUILayout and EditorGUILayout ) will take care of the DPI scaling automatically
.
.
Anyone know how can i set the title of the window on the left ?
severe python
the padding looks the same too me?
tough cairn
( bottom cutoff )
severe python
I presume thats IMGUI, if so I don't know, but anyone else would need more context
tough cairn
on the 1st screenshot the size of the box was always bigger then the scene
severe python
donno what you're doing to draw that "window"
but I'd suggest looking at the Unity Manual for the call you're using to create that "window"
tough cairn
using( new GUILayout.VerticalScope( GUI.skin.window ) ) { ... }```vertical scope? I've never heard of this before
tough cairn
its the same as : GUILayout.BeginVerticalScope()
hmmm... seems like the folks at unity created a SceneViewOverlay internal class for the particle effects GUI
where they use: GUILayout.Window( ... )
severe python
yeah I was going to say, I think the first thing is that Scope doesn't take a GUIContent and so doesn't have a label, you're just applying a style which makes it seem like it should
GUILayout.Window likely does take a GUIContent for a label
tough cairn
yea but it wakes a screen Rect ...
which will require to do the manual calculation again
eh....
tough cairn
ha solved it
var rect = GUILayoutUtility.GetLastRect();
var titleContent = new GUIContent( titleStr );
rect.y += 2f;
rect.x += ( width - 7.25f * titleStr.Length ) / 2f;
GUI.Label( rect, titleContent );
GUILayout.Space( 20f + padding );
this ^ directly after closing the window vertical scope
seems like magic numbers will never go away

Not sure if this is the right place to ask but I am trying to get into Unity Editor scripting, are there any recommended reading materials/video channels/courses on picking it up + learning more in-depth about it?
odd vessel
I have an editor script and I want to run a function on the object after the editor app has stopped running. I tried adding an event to EditorApplication.quitting in onEnable ,but either the event isn't firing or onEnabled isn't the place. how can I solve this?
odd vessel
yeah sorry, you're right. I am using it OnEnable though
I'm also using OnEnable with the EditorApplication.update event btw, which is working. it's just the quitting event I'm not sure how to use

Is there a good getting started guide on editor extensions? I want to build a tool that lets me interact with meshes in the scene view in a similar way to probuilder.
For starters just want to click on the scene view, cast a ray to find what I clicked on, and then get the mesh that it intersects.
I know how to do all the raycasting and object detection, I just don't know how to have that happen through interaction in the scene view.
versed crater
@karmic aurora
Never really found great tutorials on it. But some stuff to point you in the right direction:
You can just use the SceneView camera for raycasting https://docs.unity3d.com/ScriptReference/SceneView-camera.html
Input is a bit trickier in the scene view and generally you gotta do it with a key event like https://answers.unity.com/questions/130898/how-to-check-if-a-key-is-down-in-editor-script.html
If things aren't as snappy as you want using OnSceneGUI or whatever else they have built in, you can make a custom editor update with a bit of googling.
You can instantiate a GO to help you wherever you need in the editor and then just set it's hide and not save flags. You can also do this with additive scenes like the humanoid editor works.

Anyone know if it's possible to activate Animation mode from a script? (The mode when you have the Animation window open and the play and pause buttons become red)
I want to be able to apply a animation clip temporarily while I have a custom Editor window author time based metadata that shouldn't be encoded as animations
versed crater
@gilded flame Unsure, but this is the place to look https://github.com/Unity-Technologies/UnityCsReference/tree/master/Editor/Mono/Animation/AnimationWindow
gilded flame
Thanks
versed crater
if you DL the project and then use Visual Studio to find references to some promising things like OnStartLiveEdit you can probably find how they do it
gilded flame
It's a shame that it's all internal right now

@gilded flame ok its here https://github.com/Unity-Technologies/UnityCsReference/blob/f78f4093c8a2b45949a847cdc704cf209dcf2f36/Editor/Mono/Animation/AnimationWindow/AnimationWindowState.cs#L360

One finall other question: does anyone know if the source code for Shader Graph/VFX graph is available?
I have a graph based editor extension that I think would be about 10x less code if rewritten in UIElements
And would definitely want to see if I could get the base code node based graphs off of those two packages
feral karma
@gilded flame there have been a couple of attempts in the past to get a "basic node framework" based on what Unity has but they didn't exactly make it easy.
Problem is that they started the Graph API, deviated from it at all different times for ShaderGraph and vfx graph and now there's very little common ground between them with lots of redundant/duplicate functionality all built a bit differently. So right now there's at least 3 versions of a "Unity Graph Framework"
If someone knows about a project with a "clean" approach based on the current Graph api I would be super happy to see that :)

I'm trying to make a custom property drawer using ui elements and would like to put 3 floats in a row. With imgui I'd temporarily lower EditorGUIUtility.labelWidth so that they all fit but I'm not sure how to lower the label width in ui elements
public override VisualElement CreatePropertyGUI(SerializedProperty property)
{
var root = new VisualElement();
var longitudeProperty = property.FindPropertyRelative("longitude");
var latitudeProperty = property.FindPropertyRelative("latitude");
var radiusProperty = property.FindPropertyRelative("radius");
var longitudeElement = new PropertyField(longitudeProperty, "Lo");
var latitudeElement = new PropertyField(latitudeProperty, "La");
var radiusElement = new PropertyField(latitudeProperty, "R");
var horizontalLayoutElement = new VisualElement() { style = { flexDirection = FlexDirection.Row } };
horizontalLayoutElement.Add(longitudeElement);
horizontalLayoutElement.Add(latitudeElement);
horizontalLayoutElement.Add(radiusElement);
root.Add(horizontalLayoutElement);
return root;
}
Setting the width of the property element doesn't work

Re Shader Graph / VFX, I've recently found this effort to abstract it for reusability: https://github.com/rygo6/GTLogicGraph
But didn't actually try it yet
@gilded flame ^^
gilded flame
@tidal cave yeah I saw, unfortunately I am looking for something closer to Meccanim in construction, I just want to author custom state machines
Been trying to use that as a reference
Might just have to fork the official GraphView and make one myself
Looking at the CsReference for GraphView and it seems to all be available
tidal cave
What do you mean?
gilded flame
Didn't have time to finish my thoughts
The source code for GraphView is entirely in C#
My only thought is if it is legal to fork it give the reference only license of the CsReference repository
tidal cave
GraphView ShaderGraph based on GraphView is a package, not in main Unity source code. So it might have a different license, but unlikely.
It's Unity Companion Package License v1.0
Unity hereby grants to you a worldwide, non-exclusive, no-charge, and royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, and distribute the software that is made available with this License
(emphasis mine)
Sorry, I messed up 🙂 The above is about the ShaderGraph
tidal cave
That's not two versions. What you see in Shader Graph tool is half generic GraphView, half special code for Shader Graph. GTLogicGraph attempts to generalize on some Shader Graph features for use in different use cases.
gilded flame
Yes, what I want is direct node-node connections not port-port
And that'd require forking GraphView
tidal cave
GraphView is part of the Engine/Editor, so it is covered by Engine License, I suppose

So, I've seen a lot of different hacks to extend inspector editor instead of replacing it. Why is it not a standard feature of Unity Editor? If there is already a custom editor for a component, and I want to extend it I have to go through a lot of hacks to get that working (e.g. http://www.li0rtal.com/extending-unity-inspectors/)

extending default editors is as easy as calling the base method

Lots are internal though

odd vessel
how can I display a UnityEvent using a custom editor?
onyx harness
I guess yes.
odd vessel
... what do you mean yes? how?
just to clarify, not using the default inspector
onyx harness
Maybe a EditorGUI.PropertyField
odd vessel
I don't have a property. Or rather, it's inside a class that is inside an array property.
If there's a way to get SerializedProperty from that, that would be a good solution too. I couldn't find that either though
visual stag
odd vessel
that's just the array element it self. I need the property of an array element
visual stag
That is an element in an array
if you want to find something inside of that element, then you use FindPropertyRelative
odd vessel
yes, element in an array = array element
mm I think I tried FindPropertyRelative and it didn't work, but I'll try again. Any special syntax for "children" ?
visual stag
what do you mean by children? You can either walk down the chain of serialized properties using FindPropertyRelative
or you can provide the entire property path
odd vessel
😮 can I use array elements using the entire property path?
visual stag
yes, I forget the syntax though
visual stag
Also, you can display UnityEvents using UnityEditorInternal.UnityEventDrawer
odd vessel
😮 that's actually better! how do I actually use that drawer though?
visual stag
They might get displayed fine with PropertyDrawer, but I have used that class to create a custom version once, or just display the default field
just instance it and call OnGUI
odd vessel
lol sounds hacky but I'll take it. I'll try it, and thanks again!

@tidal cave No, because I don’t want a terrain based placement method because I am using 3D models instead of terrains because terrains aren’t scalable and always too big.

Hi everyone, is there an editor extensions that allows you to draw with 3d objects basically? Like a tilemap for 3D? I have diffrent types of 3D cubes and i want to design levels with them without having to place one after one and arrange them in a grid but instead basically draw like in a tilemap. Thanks in advance!

How do I use EditorGUILayout.DropDownButton
i've tried putting strings, textures, string arrays, texture arrays etc into this first argument (GUIContent) but it always has an error
nvm figured it out
had to create a new GUIContent
how do I use a dropdownbutton from this point on? Clicking it in the inspector does nothing
meager chasm
is it possible to remove the minimum size of an editor window?
grizzled minnow
@digital spoke Check the documentation, the button only returns a boolean, it should call on a custom GenericMenu https://docs.unity3d.com/ScriptReference/EditorGUILayout.DropdownButton.html
@meager chasm You could set the minimum size for your editor window to something tiny before opening it.
{
EditorWindow editorWindow = GetWindow<HelpWindow>(true, "Help", true);
editorWindow.minSize = new Vector2(10, 10);
editorWindow.Show();
}
oh, i tried that already, guess you have to close and re-open the window to get it to apply, whoops
onyx harness
@meager chasm put it in your OnEnable to ensure it is always set.

How would I create a custom Project view icon depending on the content of a file there?
For example, I have a folder full of prefabs, and each has the default cube prefab icon. But I want to change the color of this cube depending on the contents of each prefab.
onyx harness
@tulip plank check project's gui callback
tulip plank
Project's GUI callback? Is project a class?
tulip plank
Okay, I will hunt for the details about what you're referring to, using the clues provided. Thank you.
onyx harness
@tulip plank You are asking for a custom Project view icon.
Look at this: UnityEditor.EditorApplication.projectWindowItemOnGUI
This callback provides you the instanceID of the drawn object.
From that, you can inspect it and display whatever suits you regarding the content.

@severe python i didn't know yaml was senitive to such... infact, don't know much about yaml at all 🙂 i think i've solved it now so thanks for the help!

Does anyone here know how to display arrays with property drawers
blissful sinew
@timid cobalt I think you can do that by EditorGUILayout.PropertyField(serializedObject.FindProperty("x"), true);
Where x is the name of the array
and then serializedObject.ApplyModifiedProperties();
timid cobalt
That doesn't work for arrays
I have already tried that
It works for everything else though
timid cobalt
Ok

Hey, can someone help me with my editor method for converting Rotation Interpolation in animations to EulerAngles? When I use it it seems to be adding both rotations properties to the animation (I guess it's keeping the old CurveBindings and adding the new converted one) and when I add a line deleting the old one it deletes both. I don't know if it is because I'm editing dimension curves one by one (first I convert the x then y and z, instead of replacing the three CurveBindings together). I would really appreciate any help
onyx harness
@blissful sinew Bring some code to the table
blissful sinew
{
if (curveBinding.propertyName == "m_LocalRotation." + dimensionLetter)
{
EditorCurveBinding newCurveBinging = new EditorCurveBinding();
newCurveBinging = curveBinding;
newCurveBinging.propertyName = "localEulerAnglesRaw." + dimensionLetter;
AnimationCurve curve = new AnimationCurve();
curve = AnimationUtility.GetEditorCurve(clip, curveBinding);
AnimationUtility.SetEditorCurve(clip, newCurveBinging, curve);
//This line deletes both
//AnimationUtility.SetEditorCurve(clip, curveBinding, null);
}
}```Here's how I'm calling it
for (int i = 0; i < CurveBindings.Length; i++)
{
ConvertRotationInterpolationCurvesToEulerAngles(CurveBindings[i], animationClip, "x");
ConvertRotationInterpolationCurvesToEulerAngles(CurveBindings[i], animationClip, "y");
ConvertRotationInterpolationCurvesToEulerAngles(CurveBindings[i], animationClip, "z")
}```After using it looks like this

Hey all, I had this issue before and forgot how it was fixed. I know it was in some settings... I just updated this project from a 2018 version, to 2019.2.0f1
Here are the errors in the log:
I posted here because most of it said extension 😅
nvm, Updating the package manually fixed it.
Window -> Package Manager -> MultiPlayer HLAPI
This clear the compiling error.
However, the extension errors still persist. Pretty sure the facebook build package didn't install properly

Is there a way to actually programmatically change the icon of an item in the project window (instead of just drawing over it) ?
tulip plank
Hah yes, all the solutions online are so very hacky, as I've become accustomed to with Unity solutions.
onyx harness
Use new SerializedObject({YourGameObject})
Find the path for the {icon} and set your texture in it.
tulip plank
These are project window items, so what would {YourGameObject} represent here?
onyx harness
Use this to easily get all the paths:
public static void OutputHierarchy(this SerializedObject so)
{
SerializedProperty it = so.GetIterator();
it.Next(true);
while (it.Next(true))
Debug.Log(it.propertyPath + " " + it.propertyType);
}
Oh sorry, don't use {GameObject}, but {AnyObject}
tulip plank
I can get the guid or assetPath of one of my prefabs, for example.
These are the files/items whose icons in the project window I'd like to conditionally change.
For example, a prefab can be marked as "Done". If so, I might change its icon in the project window to a green one.
onyx harness
Hum... I think I need to clarify one thing
You can customize Icon for scripts & Prefab
tulip plank
And I definitely don't care about its icon in the Inspector window, not at all.
I care about it's "file" icon in the project view.
onyx harness
Well, the only reliable way I know is the one I gave you already
tulip plank
Right, drawing over the existing icon. It is helpful, I can make it work to some degree.
onyx harness
Unity uses few methods to fetch an icon from an Object.
tulip plank
I just wish there were a way to actually change the icon.
onyx harness
But if you want your own custom icon, you need to do it manually
tulip plank
It's okay, I can settle with an overlay now, and tweak it around to work with every zoom level (since it moves around as you change the icon view zoom)
