is there a version of that that is solid? not just a wireframe?

#

Thank you

#

won't adding a script have a performance impact?

surreal girder
#

I presume you have one already and it only runs in the editor anyway.
You can use #if UNITY_EDITOR too

Anyone else having issues with Unity Version Control lately? Getting the error: "Not connected. Trying to re-connect..." ...and when I click "Try now" nothing happens.

#

I'm working on a wizard that's adding a component to a prefab prefab, however if I look at a prefab variant of said prefab, the added component appears as removed

#

How can I fix this? Do I just add the components to the variants as well?

#

Or do I need to use something in Prefab utility?

gloomy chasm
surreal girder
#

Or you need to use PrefabUtility.RecordPrefabInstancePropertyModifications() for the changes made in code to be save-able.

#

got it, thx

gloomy chasm

i usually edit prefabs with prefab utility by opening, do my changes, then save and its usually good

How is the field and label partitioned?

Looking for a way to imitate that.

It's not 50-50.

gloomy chasm
#

I mean are you using IMGUI (Stuff like GUILayout.Button() or UIToolkit (stuff like new VisualElement())

safe sorrel
#

The Inspector is UIToolkit in modern versions of Unity

wheat notch
#

Ah, I'm using IMGUI.

safe sorrel
#

You should be able to use the...inspector(?) to look at how it works

#

(i forget the exact name)

#

ah, okay, not relevant then

gloomy chasm
#

I think fields should do it automatically when using IMGUI

wheat notch
#

It's just cause there are cases when i try to make my own custom ones.

#

I want to try a hand on a serializable nullable and just slapping a tickbox next to the field.

gloomy chasm
#

Some useful links

#

Though if you are on 2022 I would recommend just using UIToolkit instead. It is normally easier and is more modern

wheat notch
#

Aight thanks.

wheat notch
gloomy chasm
#

IMGUI is effectively obsolete in Unity 6. By that I mean, everything new is being made with UITK and a lot of the thing that were made with IMGUI have been replaced with UITK implementations.

How to check if a game object is being edited from prefab menu?

#

PrefabUtility.GetPrefabAssetType and PrefabUtility.GetPrefabInstanceStatus just says it's not a prefab.

I guess that's true.

I presume "built in" stuff is either going to have a weird/empty path or be in a package

Hello everyone, I have strange one problem with the Apple.Core package.
Plugin: https://github.com/apple/unityplugins
Available platform on my Mac:
• AppleTVOS.platform
• AppleTVSimulator.platform
• DriverKit.platform
• MacOSX.platform
• WatchOS.platform
• WatchSimulator.platform
• XROS.platform
• XRSimulator.platform
• iPhoneOS.platform
Command: python3 build.py -m simulators macOS
As you can see there isn’t visionOS listed, even though I’m not trying to build with that flag.
However when I use “add package from tarball” it doesn’t work properly.
I can’t change my Unity’s project version: 2021.3.45f1, but I know that this version doesn’t support visionOS. How can I create .tgz files with Apple.Core without visionOS?

Hi. I'm changing some stuff from an asset, so this is not my code
I wanna change the box rect size when he does Handles.Label
There's GUIStyle.fontSize
But what can i do to change the box rect size itself?

waxen cradle

waxen cradle
#

VisionOS was introduced in unity 6 I believe, so you’d need to switch to that version

wet ember
#

But I can't switch my currently project to Unity 6, it's too risky and i'm not owner of this one. Everything what I need is create a .tgz files without checked "visionOS" as one of default option.

waxen cradle
#

Well how big is the project? How much time was put into it?

wet ember
#

The worst case, I'll implement the package manually and throw "visionOs" out in the source file but I'd rather to avoid that.

wet ember
waxen cradle
#

Yeah that is pretty risky. I believe there is a workaround although it isn’t 100% guaranteed. You could try adding an AR framework to your Xcode and enabling it in unity’s XR plugin management. Might not give you 100% of the benefits though and may be quite tricky

surreal girder
#

but a project in 2021 is gonna suffer more moving forward

wet ember
surreal girder
#

packages can be used if you extract and put them in the Packages/ folder btw

#

7z and other programs can make a tar archive again anyway

wet ember
#

but it doesnt' work properly because of metadata inside of .tgz

#

or maybe I used to use wrong program to archive

#

I will check it

surreal girder
#

a .tgz is just a compressed .tar archive its not anything special to unity.
If you really are struggling then use tar to archive again on a mac/linux/wsl

#

I will say i find it very weird that apple cant just have ready made packages to download why make the user run a py script.
Or hell why cant they make the repo a valid package to begin 😐

wet ember
surreal girder
#

Tenjin is also bad they include the code they use to make the unity package IN the sdk 😐

#

@surreal girder hahaha, I just found the resolution

#

I didn't know before that a tgz is just a regular archive, so I tried to pack it again and now I noticed that when packing, it was getting packed like this: packageName/packageName/content, and that's why it wasn't working for me.

#

thank you a lot!

safe sorrel
#

I have a set of "setup" components that I've been using for VRChat worlds. I believe that VRChat completely strips out non-allowed components during the build process, so I haven't had to think about that.

I want to start using these components in other projects. I'd rather not leave a ton of components scattered all over the built game that do nothing.

How straightforward is it to strip components from a scene during the build process?

#

I see that I can implement IProcessSceneWithReport to run code during the build process

#

(these components do things like placing prefabs and resizing reflection probes -- they are editor-only)

#

I guess I'll just make them self-destruct upon entering play mode for now (or just ignore them completely)

keen pumice
safe sorrel
#

This would be to prevent the component from existing at all

#

I already use a ton of #if preprocessor directives

#

because otherwise the build explodes due to all the UnityEditor references

#

And yeah, I can just make it destroy itself during Awake

"For Prefab instances in a scene" made me tink whole objects

GameObjects I meant..

gloomy chasm
#

I am just not 100% sure if each component is processed when building. I think they are.

#

Should work for assets as well.

#

Though no clue why you would use it on an asset

keen pumice
#

ahh.. hideFlags is indeed a member of UnityEngine.Object.. so think your on the money!

young anchor
#

is it possible to make an editor extension for Unity that allows painting vertices kind of like vertex weight painting in Blender? The data you would paint can be anything

#

e.g paint 1 into uv3.x for the vertices you paint over

#

it'd be useful

real spindle
#

That reminds me of my "poor man's substance painter" unity project that I should continue working on...

#

It supports 2D/3D painting, map baking (normals, position etc), and photoshop-style layers and paint layers with undo/redo

#

Do you need to paint vertices only or also textures?

gloomy chasm
#

There is most likely a free package on github and or the asset store that does it. I know the old ProBrush package or whatever it was called could do it. Though it is really old and clunky at this point.

surreal girder
#

Polybrush?

#

oh yea it has vertex painting stuff, have a look if ths fits your needs @young anchor
https://unity.com/features/polybrush

Unity
Polybrush

Learn about the many features of Polybrush, which lets you blend textures and colors, sculpt meshes, and scatter objects in the Unity Editor. It’s now part of Unity, with ProBuilder and ProGrids.

#

hopefully it still works 😐

safe sorrel
#

for some reason, both Probuilder and Polybrush had enormous problems on my mac

#

the latter flickered like mad in the scene view

#

Probuilder also flickered a ton (and also had very weird undo problems)

#

I should look at that again in 6

Well I guess either way is the same. You just get the angle from the center of the circle to the mouse's position.

I think you can rotate textures in IMGUI... now I'm not sure though actually...

dusk dome
#

i think im just gonna stick with a vector 2 for now then lol

real spindle

It returns a float angle though but could be easily modified to return diff instead if you want a Vector2

You call it from OnInspectorGUI or similiar though, yes

dusk dome
#

okay cool, thank you!

young anchor
#

Is it possible to make an exact replica of Polybrush using UnityEditor and UnityEngine? Or because it’s a Unity official package, does it mean they might use features that normal developers don’t have access to?

#

cuz I was told this is going to be hard to build, I'm wondering if I need to use something like UnityEditorInternal, with like 0 documentation

#

i'd like to build it myself. even if polybrush fits my needs.

gloomy chasm
#

It is fairly easy to make, but a bit harder to make efficiently.

gloomy chasm
# young anchor i'd like to build it myself. even if polybrush fits my needs.

As a high level overview. The way I would do it is start by making a EditorTool for your brush.
Then when activated you get the mesh from the GameObject and sort all of its vertices in to some sort of spatial partition (like a KDTree, or Octree). Then when you paint you query the spatial partition you made to find which vertices should be painted, modify their data, and then save the data to a new instance of the mesh.

Hi all. I'm doing this in SceneView.duringSceneGui

Handles.BeginGUI();
Handles.Label();
Handles.EndGUI();

This draws a box with content, text in the scene view
But how can i control the size of the box?

visual stag
safe sorrel
#

2 is HideFlags.HideInInspector

gloomy chasm
safe sorrel
#

I was doing that in Reset(), to make it easy to run

gloomy chasm
#

To be clear, hide flags should always work. I was refering to the fact I wasn't sure if during build components are processed, so not sure if the DontSaveInBuild would apply.

safe sorrel
#

I've also just directly edited the property in the prefab asset though

#

Yeah, I'm just getting some weird results before I even get to trying DontSaveInBuild

gloomy chasm
#

Also, standard dirtying/saving rules apply

safe sorrel
#

Oh

#

I was using the wrong component lmao

#

PlaceLinearLightProbes is not PlaceLinearPrefabs

#

that explains the lack of functionality of Reset, at least..

#

Is this insufficient to get Unity to look for changes on a prefab?

        [ContextMenu("Test")]
        void Test()
        {
            this.hideFlags = HideFlags.NotEditable;
            UnityEditor.EditorUtility.SetDirty(this);
        }

This works in the prefab view, but it doesn't prompt me to save the prefab, and the changes aren't persisted

#

either way, the flags don't stick to prefab instances, interestingly

surreal girder
#

I think a prefab stage is a scene technically but im not sure how you make it be dirty correctly

#

perhaps you can grab the current prefab stage and the stage scene as dirty

safe sorrel
#

oh wait, this is for sub-assets of prefab assets

#

also interesting: setting the m_ObjectHideFlags property doesn't do anything persistent, but m_EditorHideFlags does modify the prefab asset

real ivy
#

But got it figured out
Using HandleUtility.GetHandleSize, and GUIStyle.fontSize also determines the box size

blissful sky
#

Hi, is there a way to optimize pro-builder's work? It lags really hard (sometimes freezes for like second or two) on some meshes when selecting vert/face/edge and doing anything with them, even thought the mesh has only 370 triangles! Somehow it sometimes works just fine on a lot heavier meshes though...

real spindle
blissful sky
#

Okay, so the thing is you shouldn't use not unpacked prefabs if you are working with them using pro builder...

I wish you could install an editor asset to a Unity version rather than having to add it to every single project.

Hi. I changed a field from an enum TileRuleMaskRotation _neighborShapeFilter, to TileRuleMaskRotation[] array

How do i update this code?

            for (int c = 0; c < 4; c++)
            {
                TileRuleMaskRotation rot = (TileRuleMaskRotation)c;
                var neighborShapeFilterField = UI.createEnumFlagsField(typeof(NeighborShape), "_neighborShapeFilter", serializedObject, rot.ToString(), $"NeighborShape {rot}.", toolbar);
                neighborShapeFilterField.RegisterValueChangedCallback(p =>
                {
                    applyNeighborShapeFilters();
                    populatePrefabViews();
                });
                neighborShapeFilterField.style.maxWidth = 100.0f;
            }```
real ivy
#

I try _neighborShapeFilter.Array.data[0]
But nullrefs

#

if i found two folder assets with something like AssetDatabase.LoadAssetAtPath (path, typeof (DefaultAsset))

Do I have to manually crawl them and see if they contain each other? 🥲
Can I crawl up? (instead of "get children" something like "get parent"? 🤔 )

Hi everyone,
I’m working on a custom editor script to create a conversation timeline for my Unity project. I’m using Unity version 2022.3.41f1, and I’ve been following the documentation for EventType here: https://docs.unity3d.com/2022.3/Documentation/ScriptReference/EventType.html.

But like i get an EventType error for events like MouseDown, MouseDrag, and MouseUp.

Assets/Editor/ConversationTimelineEditor.cs(149,33): error CS0117: 'EventType' does not contain a definition for 'MouseDown'
Assets/Editor/ConversationTimelineEditor.cs(156,38): error CS0117: 'EventType' does not contain a definition for 'MouseDrag'
Assets/Editor/ConversationTimelineEditor.cs(162,38): error CS0117: 'EventType' does not contain a definition for 'MouseUp'

I'm really not sure whats going on but maybe im missing a namespace or im looking at the wrong section of documentation like the wrong version

heres the section im refering to and a pastebin of the full code: https://paste.mod.gg/ipjhtliiejvg/0

private void HandleEventDragging(Event e, Rect timelineArea)
{
    if (e.type == EventType.MouseDown && timelineArea.Contains(e.mousePosition))
    {
        // Start dragging
        isDragging = true;
        draggedEventRect = new Rect(e.mousePosition.x, e.mousePosition.y, 100, 20);
        draggedEventName = "New Event";
    }
    else if (e.type == EventType.MouseDrag && isDragging)
    {
        // Update position
        draggedEventRect.position = e.mousePosition - new Vector2(50, 10);
        Repaint();
    }
    else if (e.type == EventType.MouseUp && isDragging)
    {
        // Drop event
        isDragging = false;
        PlaceEventInTimeline(draggedEventRect, timelineArea);
    }
}

as far as what ive done to resolve it, not much beyond research. i havent edited the code too much because idk whats wrong at all.

also this method gets called in another method which is called in OnGUI (for more see the full code)

and thank you in advance to all/any who help 🙏

Thank you for the suggestion, I think I’m already using that name space but I’ll try the hovering trick when I’m back at my dorm 🙏

gloomy chasm
#

I mean that you shouldn't be using that namespace 😛

topaz ivy
#

But would that be causing an error though? Like will removing that really do anything? Just curious cus I don’t normally fix an error that way. Removing an unnecessary namespace. I’ll try it as soon as I can though

gloomy chasm
topaz ivy
#

it doesn't, ive just commented it out but the error persists. good point though. i thinkt the name space is just for ui elements like colors and buttons though i used it in an earlier script that i based this none off of and in that earlier one i had used different colors so thats why its there. i dont think i use it in this one but its not harming anything. Ill leave it out though since removing it didnt add or remove any errors

crisp rapids
#

Similar to what mech warrior suggested above, could it be that your script is not referencing the correct EventType Enum?

#

EventType is such a vague name that I can imagine multiple exist

topaz ivy
#

I FIGURED IT OUT, maybe... i think its a syntax error 😭 im pretty sure its mouseUp and not MouseUp and mouseDown and not MouseDown.

i added the line

Debug.Log(Event.current.type); that revealed this 🤦‍♂️

topaz ivy
# crisp rapids EventType is such a vague name that I can imagine multiple exist

no i don think so i think its just poorly named (i mean i also have things with the word "event" used throughout the project unrelated to this so i cant blame them) im aware of what the problem seems to be i think the documentation is just wrong? or i looked at the wrong documentation? the debugging reveals a different syntax so imma just plug that in and see

gloomy chasm
#

If not then your IDE is not setup correctly

topaz ivy
#

it shows up in the IDE, but when i do EventType. nothing special happens theres no drop down with options... the documentation features code that looks like what i originally wrote and when i debug to see the current event's type it returns mouseUp mouseDown``mouseDrag and so on but even after chaning M to m it doesnt work 😭 i wasnt really onto anything i guess also idk if my IDE isnt setup properly i mean i think it is but idk cus i only do things as problems arise i didnt really set it up i just downloaded things as i got errors that they were missing...

blissful burrow
#

okay I feel stupid SCWWcrying I can't figure out how to properly detect whether a user is holding the camera movement button in the scene view

surreal girder
#

the right click wasd movement?

blissful burrow
#

theoretically it would be Tools.viewToolActive but it's false while holding alt for the orbit camera, it only kicks in and is true once you press LMB/RMB/etc

#

not sure if it's the same issue with the RMB first person camera, but I suspect it's got something to do with execution order

#

basically I need to override selection in my OnToolGUI, but I don't want to override camera movement

#

and for whatever reason I can't get it to cooperate, either the scene view selection is captured, and I don't intercept it at all, or, my script does intercept selection, but then the scene view is in a weird state where I can't give control back to the scene view camera anymore, so I can't turn the camera

#

I could probably solve it with an if event modifiers HasFlag(Alt) thing, but that kinda feels like a hack in case people have rebound it

#

okay yeah that pretty much solves it

#

bool IsUsingCamera => Tools.viewToolActive || Event.current.modifiers.HasFlag( EventModifiers.Alt );

#

but it feels a little gross

surreal girder
#

Is this to ignore a left/right click so it doesnt "select" a thing? (im guessing this is for your mesh editor thingy)

blissful burrow
#

yeah! it's for my spline plugin in this case

#

but same thing

#

(basically I need to make a custom box selection)

#

but also, I just looked at the keyboard shortcuts rebind menu, and I don't think it's actually possible to rebind the camera alt key, so that indirectly solves the problem ahah

surreal girder
#

Pro builder appears to react to a left click visually if i hold ALT but not actually do a selection so there is some weirdness it seems 🤔

blissful burrow
#

half-edge (my 3D modeling tool) is standalone now so I don't have to deal with scene view conflicts henlo

#

ah wait no hold on something is wonky still, this doesn't solve it entirely

or, uh, no, it does work, but sometimes something goes a little wonky

#

might've been me forgetting to check which mouse button was pressed/released

Hey, I'm working on an editor tool to create an "Ingredient" prefab for a project I'm working on, every ingredient is identified by it's own C# script which inherits from the Ingredient class, so when I'm creating a new prefab I also need to create that script.
as of right now it is successfully creating the script and the prefab but when creating the prefab it doesn't wait for the scripts to compile and adding the Ingredient class instead of it's newly created derived type.
Is this a consequence of it not waiting?
if so how do I make sure the editor script waits for the scripts to recompile?

surreal girder
gray idol
#

That makes sense
I searched it up so you mean to make a function with the
[UnityEditor.Callbacks.DidReloadScripts] attribute?

surreal girder
#

Yea. your code is going to fully execute and then the editor will do the recompile and reload. Then you should get the call back. You will have to store some info somewhere persistent to react post reload

gray idol
#

Okay, Thanks

#

That's a lot simpler than i thought

safe sorrel
#

In my editor scripts, I am moving away from modifying C# objects and towards using SerializedObject/SerializedProperty to make all modifications.

Is there any reason to avoid reading C# objects? Assume that nobody else has been modifying the objects, since that'd obviously mean that the C# data doesn't match the serialized data anymore.

#

for example, I am writing a script that removes badly-placed light probes

#

I am getting the serialized property for the probe positions and updating it properly

#

But I'm currently just grabbing LightProbeGroup.probePositions instead of reading from the serialized property

gloomy chasm
safe sorrel
#

Right.

gloomy chasm
#

For consistency though, and to avoid any potential bugs I generally always do my reading and writing via SerializedProperty

safe sorrel
#

I guess you might as well go all the way

#

so that you get used to interacting entirely through SerializedProperty

gloomy chasm
#

Yeah, I think it would also make the code easier to read

safe sorrel
#

...maybe :p

# 
Vector3[] positions = new Vector3[prop.arraySize];

for (int i = 0; i < prop.arraySize; ++i)
{
    positions[i] = prop.GetArrayElementAtIndex(i).vector3Value;
}
#

not the worst

#

I do have the lingering fear that I'm using SerializedObject/Property totally wrongly

#
  • Construct an SO out of the target object
  • Get properties and modify their values
  • Call ApplyModifiedProperties
#

That seems to be the Right Thing

gloomy chasm
#

On larger projects I generally have a wrapper class that is something like

class SerializedPropertyArray<T>
{
    SerializedProperty _array;

    public T this[int index]
    {
        get{ return _array.GetArrayElementAtIndex(i).ExtensionToGetValue<T>(); }
    }

    public SerializedPropertyArray(SerializedProperty array) { _array = array; }
}

(It also implements things like IList<T> and what not for easy access)

gloomy chasm
#

SerializedProperty is sadly very old (close 20 years?) and clunky to use. So we kind just gotta deal with it :/

surreal girder
#

i never use it i just use the c# object. for prefabs i use prefab utility to load it. as long as its set as dirty it should be good

gloomy chasm
surreal girder
#

if you use PrefabUtility.RecordPrefabInstanceModifications() it should pick up such changes

#

to my memory i havent had many issues yet doing it this way

safe sorrel
#

it feels a lot more...murky that way

#

you have to cast a bunch of magic incantations or it explodes

surreal girder
#

i much prefer it to needing to grab the serialized property for anything i wish to modify. For what i usually automate in terms of scene or asset modifications its been fine so far

gloomy chasm
#

Yeah for doing automated processing it makes sense to do it manually normally I find. Though that is more of an exception than a rule for me.

wanton arrow
#

really weird, so for some reason the wwise integration isn't working with unity 2021 (the label on Wwise.Event properties doesn't show up (if you know a fix for that lmk)) and not finding anything else i am debugging the editor code, and it seems the label is fine when it enters the function but the GetPropertyHeight Method sets its text to null. If I remove this line of code then it works, but the height is wrong. Whats going on here???

is this just a straight up bug

gloomy chasm

Sounds like a bug

gloomy chasm

Yeah it is a bug, but not sure if it is Unity or WWise

gloomy chasm
#

There is a virtual method that is a memeber PropertyDrawer by the same name

wanton arrow
#

i guess its a unity bug

gloomy chasm
#

Yeah seems fine, my guess is a Unity bug. But surprising.

waxen sandal
#

You sure that objectreferencevalue is not null?

#

Sometimes those things can break during updates etc

wanton arrow
#

well the method isn't being called

#

as far as I can tell

#

unless?

#

unity calls that?

gloomy chasm
#

Also, they are not disposing of the SerializedObject, tsk tsk tsk.

wanton arrow
#

idk how any of this would modify the contents of the label

waxen sandal

Hi all. I have a struct[] in an SO that doesn't survive editor close open

public struct NeighborShape : IEquatable<NeighborShape>
{
    // store as edges
    [SerializeField]
    public List<int> edgeHashesList;
}```
The SO

public class TileRulePrefab : ScriptableObject, IUIItemStateProvider
{
[SerializeField]
private NeighborShape[] _neighborShapes = new NeighborShape[4];
}```

#

The weird thing is, when i populate this within a unity session, when inspected, each of these lists are empty, even tho in code/debug log, they're not empty

real ivy
#

Oh wait, is struct not serializable?

gloomy chasm
#

No structs are serializable.

real ivy
surreal girder
#

edit it only with the debug inspector, manual save and re open and see?

gloomy chasm
#

I mean it looks fine. Yeah do what Rob said, it might be Odin.

surreal girder
#

Yea may be the cause, if you edit it with odin and the file fails to change then you know

real ivy
#

What do u mean by edit with odin?

surreal girder
#

that looks like odin inspector and not the generic unity inspector ui

real ivy
#

TileRulePrefab are generated when i add some prefabs to this asset's own prefab library. I added custom stuff upon the creation to init the NeighborShape[], and the edgeHashesList in each of them. They're added properly, and the system that uses it are using it just fine
So, no i don't edit the list/the structs from odin inspector

surreal girder
#

if editor code, make sure to set the asset as dirty so it can be saved.
Check the asset to see if the changes appear at any point or vanish at any point

safe sorrel
#

It's easy to create data that doesn't survive a reload

#

even though it appears in the inspector

surreal girder
#

indeed. If it doesnt know its dirty or you dont save it manually it will just go poof

safe sorrel
#

I had a great time generating animator controllers through code

#

If you don't make sure every single object winds up saved somewhere, it won't get saved to disk

#

e.g. blend trees

surreal girder
#

was that with importers? i've had issue making them save shit before

safe sorrel
#

ah, no, not with an importer

#

the most I've done with model importers is rewriting mesh data

You can just do

ok so im a bit out of practice and this line in a property drawer is causing
ArgumentException: Getting control 1's position in a group with only 1 controls when doing repaint

anybody know why this might be?

#

I saw a thing that said EditorGuiLayout isn't allowed in property drawers but I am using it just fine in another class

visual stag
#

you shouldn't be using it in any drawer.

#

It'll always draw after every other property if you used it, which is incorrect behaviour

wanton arrow
#

ugh

#

editorgui is so clunky to use

visual stag
#

Why are you using IMGUI?

wanton arrow
#

im not familar with the alternatives

#

theres like a visual element system?

visual stag
#

If you use UI Toolkit it handles all the layout for you

#

yes

wanton arrow
#

but then I have to learn that 😵‍💫

#

do you have any resources that would cover property drawers

visual stag
#

it shows UITK and IMGUI alternating

wanton arrow
#

right

#

isn't there a visual interface thing

#

or am I thinking of something else

visual stag
#

Sure, though I don't really know why you would need to use it unless you were building something really complicated and weren't comfortable with code or UXML

wanton arrow
#

i feel like that would be easier

visual stag
#

I presume your code above would just be
public override VisualElement CreatePropertyGUI(SerializedProperty property) => new PropertyField(property.FindPropertyRelative("type"));

wanton arrow
#

the code above is like

#

just the very first part of it

#

there will be a lot more

#

yeah there's style sheets and such

visual stag
#

Sure, well you can do things via UXML or the UI Builder (which produces UXML) and then reference and clone the UXML, and bind to that

#

and reference style sheets in your UXML

#

Or you can do it all via code

#

with Property Field there's very little reason to write large editors unless they're totally custom setups that are tailored to a single UX like Timeline or Sprite atlas editors

wanton arrow
#

i should probably note im using unity 2021

#

its reccomended for 2021 to use imgui? I wonder why

visual stag
#

Mmmm, UITK is definitely more consistent in later versions. But I've been using it in the editor for a very long time

#

It's hard to give good recommendations for a version I've long forgotten 😄

#

I can't remember if it used UITK as the default Editor in that version

#

If you use IMGUI or UITK you should be amply using PropertyField, both have different versions of it

wanton arrow
#

do you know how id make a popup with categories in UITK

#

i know that sounds weird but hold on

#

nvmd I can't find examples

is there a way to prevent adding / hiding a third party behaviour?
I am using a plugin that includes a behaviour that confuses designers and they end up adding it where they shouldn't.
Can I hack something to hide it from the add component list or something? (without editing the plugin, if possible 🤞 )

#

The source list appears to come from Unsupported.GetSubmenus("Component"), a native binding, so no luck there. But from there, there is some filtering performed. Most notably:

if (!hasFilterOverride || ModeService.Execute("inspector_filter_component", targets, menuPath))

I have no idea what ModeService is or what it's for. It is public, but not documented. It seems to be a service for managing different mode the editor can be in and I guess some components can be filtered in different modes.

seems like you have to have the inspector be UIEements too? probably (hopefully) a unity 2021 thing

#

this manual is ass

it doesn't tell you how to get a property from the desired object

#

ok u just use serializedObject

#

now im getting this

which i have no idea how to parse

#

seems to happen when I render a list inside a list

#

dk what im supposed to do to fix that tho

wanton arrow
#

ok I just had to make my own list renderers

#

issue is now how do I update the ui? I have a button that adds an element but idk how to make it refresh the list

#

I tried to add an element in the button code but that doesn't work, it only updates if I close and reopen

safe sorrel
#

my understanding is that, with UIToolkit, you need to bind the UI elements to serialized properties

#

with IMGUI, your code runs every time the UI is redrawn. that's not the case with a retained-mode UI.

visual stag
#

Yeah this is a 2021 thing. I think the nested list thing was also a problem that was fixed in 2022.
I'm sorry for the recommendation, in your case due to the old version it might not be best
However if you use IMGUI for a property drawer you'll have to manually calculate the height of your properties in GetPropertyHeight and manage the rects yourself.
In an Editor you can use GUILayout

Bit of a weird request but does Unity have anything that allows me to prevent specific renderer components from drawing in scene view, without actually disabling them?

acoustic otter

Ooo maybe. Ideally i'd prefer to handle it more on the scenes end of thing's and not mess with the actual content but I would prefer this over disabling the component, thanks

acoustic otter
#

If the tool isnt going to be running during play mode, be careful. It may be possible that this flag can get serialized to the scene/prefab data. Id run a test first to be sure. It doesnt appear in the properties drawer for MeshRenderer, or its debug options, but always double check!

queen wharf

That would definitly be a better choice

use that

When Unity fails to install checklist
  • Make sure you have enough space including on C: drive.
  • Check that it's not being blocked by antivirus/security programs.
  • Look through the logs for a real reason why the setup fails they are pinned [here](#💻┃unity-talk message).

If you still have issues, perform a clean install in another location:

  • Install the Hub and Unity in a non-system drive or a clean new folder in the root of C: drive.
  • Failing that use the recovery Refresh option or reinstall OS entirely then repeat the previous step.

I'm using an AssetPostprocessor to modify some of my FBX imports. However, Reimporting the asset triggers a consistency error.

Importer(FBXImporter) generated inconsistent result for asset(guid:8860e14097e834844b851dcf1953b64e) "Assets/SM_Suzanne.fbx"

This is normal behavior from what I can tell, as I am add/deleting objects from my AssetPostprocessor script.

(moved from #archived-code-general) I'm having issues with my PropertyDrawers not actually binding the values of a PopupField in the inspector. What's the most appropriate way to share the code I've got so far without flashbanging the channel?

I think I might be able to show just the following. While the dropdowns are available in the inspector as hoped, they do not actually bind to the associated EL1 and EL2 variables in the Character class. None of the changes are saved or reflected.

and after i hit play it stays like that

i presume when you play the domain reload causes the non saved changes to vanish

Reward is an abstract class, and the different types of rewards extends this

this is the SO

But a Debug.Log in the if(GUI.changed) statement to see for sure if it is getting called

ripe ice
#

it does

ripe ice
#

i solved it. Seems like abstract class are not serialized even if the subclasses are set to serializable. I think its because the main type is of Reward. I just made the reward class an interface and everything works like a charm!

I'm surprised anything was showing up in the inspector at all

Hello, I have a bit of a problem while working in PropertyDrawer.
I wanna show a variable in the inspector, so I do:

EditorGUI.PropertyField(valueRect, serializedProperty);

It works when serializedProperty is an int, float, array, etc, but if it's a custom class or struct (even if Serializable) it just draws a dropdown which when opened shows nothing. What could be wrong?

twin dawn
scenic rampart
#

ok I figured it out sorta? Seems like a EditorGUI.PropertyField skill issue, using EditorGUILayout.PropertyField works. Honestly no idea what the difference is but it works

#

oh wait bruh you just have to set includeChildren to true 🤦‍♂️

#

should be set to true by default imo but thats just cope from me tbh

visual stag

wanton arrow
#

hey so for some reason my custom editor is super laggy and im not sure exactly what to do about it

the way it works is I have one StateMachine ScriptableObject asset. This has a list of State each state has lists of StateActions. In order to allow the StateActions to be serialized they are not polymorphic, and instead have enum to list all the different action types, and then have all the possible parameters of each type of action and only the relevant ones for the current type are shown.

one of these is a list of actions in and of itself, to allow for if conditional blocks basically

everything actually seems to be fine until I add an elseActions list, then everything gets suuuuper laggy. Looking at the profiler the call thats taking up the most time is OnGUI? which is weird because lm using UIElements not IMGUI from my understanding

image.png
#

yeah

#

it doesn't even have to be like

#

shown or anything

#

i just add it to StateAction and it lags the fuck out

safe sorrel
gloomy chasm
#

You can turn on the deep profiler mode to see specifically what is taking up the time.

wanton arrow
#

and then if I use [SerializeReference] on my list of StateActions

#

it will let me have a list with different types in it

#

without having a bunch of assets for every single action

#

I still am not 100% sure that would even work

gloomy chasm
#

Yeah fields with the [SerializeReference] attribute will serialize the field as a reference type instead of a value type. This means it supports polymorphism along with null values.

wanton arrow
#

the issue seems to be the second list of actions just existing

#

and both lists would exist on the same type of StateAction

#

so im worried I got to all this trouble and it doesn't help

#

why would my solution be laggy anyway? I dont get it

gloomy chasm
#

Yeah the [SerializeReference] thing is a separate note for how to improve your system. Unrelated to your performance issue.

wanton arrow
#

ok

#

it is helpful ty

gloomy chasm
#

For the performance issue, I would enable deep profile to see the exact call stack for the OnGUI method

#

Also make sure you don't have the IMGUI or UI Elements Debugger window open

wanton arrow
#

what are those

gloomy chasm
#

Windows used for debugging the layout and styling of IMGUI and UIElements/UIToolkit respectively.

#

But since you were not sure, I assume you probably don't have them open haha

safe sorrel
#

I wonder if you're having problems with recursive serialization

wanton arrow
gloomy chasm
#

Dang you called it

wanton arrow
safe sorrel
#

n steps

wanton arrow
safe sorrel
#

to 2^n steps

wanton arrow
#

fair

#

would the SerializeReference solve that? i have no idea

#

its weird bc why would recursive serialization be a big issue, most of the arrays are empty so it should just skip over it

gloomy chasm
# wanton arrow

If you look at the call tree, OnGUI is being called from IMGUIContainer which is a UIToolkit VIsualElement used for drawing IMGUI within UITK

wanton arrow
#

right but when would that be created

#

a PropertyField?

gloomy chasm
#

Yup

wanton arrow
#

why???

#

unity why would you do that

gloomy chasm
#

If there is a PropertyDrawer that doesn't implement CreatePropertyGUI and only OnPropertyGUI

wanton arrow
#

right

safe sorrel
#

UIToolkit can embed IMGUI (but not the other way around)

wanton arrow
#

I tried to make sure I never did that

gloomy chasm
#

As for the serialization. It depends on how your class' are structured.

#

If you have something like

class A
{
   public B[] Bs;
}

class B
{
    public A A;
}

That will mess it up.

wanton arrow
#

weird

#

why wouldn't it be

B:

#

fuck

gloomy chasm
#

because it serializes it as a value, and values cannot be null

wanton arrow
# 
A
  Bs
    0:
      A:
        Bs (empty)
    1:
      A:
        Bs (empty)
#

idk if that makes any sense

#

whats the issue with that

#

its would only be recursive if Bs wasn't an array

gloomy chasm
#

Yeah, it should be okay, but maybe the serializer is still struggling with it. Or maybe it isn't as straight forward. (Again it really depends on exactly how the classes are layed out).

wanton arrow
# 
[SerializeReference] public StateAction[] ifActions;
[SerializeReference] public StateAction[] elseActions;

tried this for shits and giggles
and now im getting an error on this

property.FindPropertyRelative("type").GetEnumValue<StateAction.Type>()

is there some issue with getting elements of ifActions as a property? I would need to feed it a serializedObject somehow?

image.png
gloomy chasm
#

Because the value of a StateAction can be null

wanton arrow
#

ohh

#

do I still get it as a property like normal

#

just somehow check if its null? idk how to do that

#

oh its like

#

objectReferenceValue or something

#

StateAction needs to inhert UnityEngine.Object right?

gloomy chasm
#

No, when you serialize a field with SerializeReference it change it so the value can be null.

#

Or polymorphics

wanton arrow
#

ok ty

#

why am I getting type is not a supported pptr value when trying to check if its null

#

property.objectReferenceValue == null maybe its failing because its null? how else would I null check

wanton arrow
#

ok so

#

turns out making all lists of StateActions into serialized references actually worked a treat

#

its running fine now

#

I could convert it into polymorphic types but I honestly kinda like the enum version? It makes it easy to swap between types

Hello, I made my own PropertyDrawer script for an object. I then created an array of this object. If I add to this array and then press undo I get this error:
ObjectDisposedException: SerializedProperty [blabla].Array.data[1] has disappeared!
Is there something specific you have to do to handle undoes?

Hey all, I’ve been working on a suite of extensions I want to sell on the asset store, and it relies on some common extensions I use not only in this package but in general, so I’m wondering if it’s possible to import those additional extensions (e.g. by getting them from a public git repo) as a separate process when a user imports the main package. If not I can always just include a copy of the latest version of that code as part of the main package, but I was just wondering if that’s possible or if maybe it’d be blocked since it would be importing data that Unity did not verify with the package.

@crisp rapids @wild edge I would make sure to read the TOS and EULA. From what I remember, you are not allowed to download Packages automatically or even with a prompt (meaning a package manager, package). And all contents of a Unity AssetStore asset must be contained in the asset it self.

They could have changed it or I could be misremembering. So doubleing check your self is a good idea.

crisp rapids

Thanks

# wild edge you should tell that to the assets that break the TOS/EULA, i'm just reporting w...

Sorry if it came off as I was trying to correct what you were saying. I have no doubt that there are assets that are doing it (that are not Verified Solutions Partners). The checking process isn't that great.

I just know from what I have seen that Unity takes rules about external downloads or verification more seriously than there other rules when reported. So while others do it, I can't recommend it.
Unlike other things like Harmony, where 'lots' uses it and Unity doesn't really care haha.

If they stopped using .unitypackage for asset store stuff it would be a lot easier

So, I have a bunch of objects that have procedurally generated meshes and materials and a bunch of scripts on them. I want to save these to an asset to re-use later without needing to re-run all the stuff that generates them. I tried saving the objects as prefabs, but they were missing the procedurally generated assets. How could I serialize an object to a prefab and keep all of this intact?

gloomy chasm
simple bloom
#

Yeah, I need to know how I can save all these meshes as an asset

gloomy chasm
#

Hard to recommend since I don't know the use-case. But the most straight forward would be to get GetComponentsOfType<MeshFilter>() on the root GO and then check if the mesh is persistent, if not, then save it as an asset.

#

Not really sure there is a better option.

simple bloom
#

So, recurse through all children, save the asset somewhere, change the object to use that mesh instead of the procedural one, and once finished, use PrefabUtility to save it as a prefab?

#

Saving the mesh is as simple as calling AssetDatabase.CreateAsset and passing in the mesh, right?

gloomy chasm
#

And yeah you can just do CreateAsset, I think unity uses the extension .mesh for mesh assets.

#

You also just run this as a MenuItem and then manually drag-and-drop the GO to create the Prefab normally

simple bloom
#

How would I go about checking if a mesh already exists as an asset? All the ways I can find to check involve checking if a path contains an asset, but I need it backwards - I need to check if an asset exists at any path

gloomy chasm
#

EditorUtility.IsPersistant or I think AssetDatabase.Contains would both work

simple bloom
#

Okay, it didn't die this time, I'll have to wait a bit to see if it actually manages to finish. It's a large object

gloomy chasm
simple bloom
#

Dang

#

That would certainly speed thigns up

gloomy chasm
#

Yeah I should have mentioned that before hand, I thought about it haha

simple bloom
#

Welp, if I missed anything, I'll be sure to use that before running it again

#

You know, considering there's several thousand mesh files to create I probably should just force quit it and try again

#

Definitely a good call. Took about twenty seconds to generate as much as it did in twenty minutes before the change

simple bloom
#

Okay, got all the meshes working. Is there a good way to save all materials and their textures as well, or am I gonna need to drill down into the shader properties and look for everything with an image set?

gloomy chasm
simple bloom
#

Thankfully, they're all using the same shader so once I find the properties I can just apply it to all of them, but I'll need to write the images out manually from the data

simple bloom
#

Almost there. Getting problems saving Normal Maps. My guess is it's this fucky way I apparently have to save a compressed texture:

Texture2D baseMap = mat.GetTexture(shaderPropName) as Texture2D;
if (baseMap != null)
{
  RenderTexture renderTexture = RenderTexture.GetTemporary(baseMap.width, baseMap.height);
  Graphics.Blit(baseMap, renderTexture);
  RenderTexture.active = renderTexture;
  Texture2D dest = new Texture2D(baseMap.width, baseMap.height);
  dest.ReadPixels(new Rect(0, 0, renderTexture.width, renderTexture.height), 0, 0);
  dest.Apply();

  File.WriteAllBytes($"Assets/Temp/Textures/{mat.name}_{suffix}.png", dest.EncodeToPNG());
}

Attempting to save it normally says I can't save a compressed texture and from what I can see there's no way to un compress it other than this rendertexture hack. The issue with this is that the generated normal maps are very wrong. First image is original normal map that is part of the runtime-loaded asset. Second picture is what this process spits out.

image.png image.png
surreal girder
#

perhaps the render texture format was not matching so it fucked the pixels?

simple bloom
#

How would I find out what format the texture is in? Are Normals usually in a different format than RenderTextureFormat.default?

surreal girder
#

id make it the same as the baseMap and see if that resolves anything

simple bloom
#

Okay, regenerating

real spindle
#

Normal maps might need some special format because they are in the (-1...1) range instead of (0..1)

surreal girder
#

that is done in shader, and ofc if you are generating normals in code, you remap before writing the pixels

simple bloom
surreal girder
simple bloom
#

I don't know if that error came up on the normal map or one of the other textures

surreal girder
#

check the stack then?

simple bloom
#

Okay, it's the main texture. Not sure how knowing which one is the issue helps though

surreal girder
#

Can you just create a normal texture instead of a render texture? hopefully if you just get all pixels from the compressed ver and set in a non compressed one you can write to disk.
DXT is for gpu use only (so dont use that format for the new tex to write to disk)

simple bloom
#

I'll give it a shot. I only ever found people suggesting to use render texture when saving a compressed texture. Let's see if that's just cargo culting

surreal girder
#

Well DXT compression is good for gpus as its natively usable but in a file i presume unity cannot convert dxt -> rgb -> png

simple bloom
#

Right, that's what I'm trying to circumvent with the rendertexture thing

surreal girder
#

but its default format may be something better suited for gpu use once again

simple bloom
#

It doesn't matter if it's better for the GPU if I can't save the file

#

I need to be able to save the texture as a file, so I need a way to un-compress it

surreal girder
#

So try what i suggested, make a new texture in say RGB24, get pixels from compress tex and set pixels in RGB24 tex, then save to png.

simple bloom
#

Trying that now

#

It takes a while to run the conversion

#

Well, it hasn't died yet so it's not an error, but I have to wait for the conversion to finish to see if it saved the image properly

surreal girder
#

if it takes this long i hope you can upgrade from your potato

simple bloom
#

It's not a potato, it's that it's working on about a gig and a half of meshes

#

Doesn't help that all the futzing with the asset database means I have to restart unity a bunch

#

So, good news, it didn't save the normal as orange.

Bad news, it saved it as this

image.png
#

which is somehow even less useful

#

I'm going to try some other ways to copy the pixel data over

surreal girder
#

you may need to debug on the pixel copying cus something is certainly wrong

simple bloom
#

Graphics.CopyTexture did not work

#

But there's a bunch of other ways to do the copy

#

CopyPixels also no dice, it says there's an array size mismatch, despite the fact that the destination texture is literally created with the exact dimensions. Probably because of compression making the size not actually equal to the size?

#

Fuck it, for loop and math

#

Okay, GetPixels literally cannot be used on these textures since they don't exist as a file already

#

I'm out of ideas

surreal girder
#

is read/write enabled for this source texture? @simple bloom
Otherwise unity may not be able tocopy/have the pixels cpu side.

simple bloom
#

There is no source texture

#

They're part of a runtime-loaded mesh I'm trying to turn into a texture file

#

The whole point is to save it as a file

surreal girder
#

then you need a gpu only copy to a texture that is read/write able

simple bloom
#

that is what I am trying to do

#

I'm trying to copy this into a texture that I can then write

surreal girder
#

its confusing me even, there should be a way to make it work :/

simple bloom
#

I have a texture that only exists in memory and I want to save it as a file. I can't do AssetDatabase.CreateAsset since it can't create image files. I can't do EncodeToPNG because it's compressed. I can't do GetPixels because it's only in memory. CopyPixels shows an array size mismatch even though the definition was created with new Texture2D(baseMap.width, baseMap.height). Blitting it to a render texture works for everything but the normal map.

surreal girder
#

my last idea is a gpu copy to a read/write texture that is created with a DXT format, then you can get pixels cpu side and hopefully then unity can correctly convert to RGB, then write to new texture in some RGB format.

or perhaps a compute shader can do something 🤷‍♂️

#

the issue is probably the DXT to RGB conversion. I have used libs to do this conversion but not in c# (rust, cpp)

short tiger
#

But apparently you should be able to import DXTnm format normal maps directly in the editor.

simple bloom
#

Okay that definitely explains the why. Now I just need to find out the "how" of a fix

short tiger
#

You could either do the channel swapping with a custom blit shader, or make sure to save all channels, including alpha, and then use the new swizzle option in the texture importer to do it manually.

surreal girder
#

dang good catch, unity bullshit strikes again

simple bloom
#

Okay, so, alpha channel of the in-memory texture becomes red texture of saved normal map. Green channel remains unchanged. What about blue?

#

Or is that just always 1 and that's why the normal map is always so purple 🤔

short tiger
#

It will be white, which is standard for RGB encoded normal maps, so you can leave it as is

short tiger
simple bloom
#

I'mma be real with you have I zero clue how to use that so I'm gonna try to transfer it over using a nested for loop and hope that works too

short tiger
#

Gonna take forever, vs no difference with a custom blit shader over the standard one

#

Just make a material using this shader and pass that into Graphics.Blit

simple bloom
#

And then blit the baseMap onto that instead of the temporary renderTexture I'm currently using?

short tiger
#

No, everything else stays the same, you just specify a custom blit material

#

The blit shader is responsible for copying the source to the destination. The default blit shader, when you don't specify one, just reads the texture and returns it. This one reads it, swaps the alpha and red channel and returns it.

simple bloom
#

Ah, okay, so it's a third parameter to blit. Okay, I'll give that a shot

short tiger
#

To make the material, it's simplest to just create it from code: var blitMaterial = new Material(Shader.Find("Hidden/DXTnmToRGB"))

simple bloom
#

Good I had hoped that was the easiest way because threading through a material to this otherwise was gonna be annoying

#

Moment of truth

short tiger
#

The shader is untested, written from memory, so it might be missing some detail.
I see now other blit shaders often have this line:
ZTest Always Cull Off ZWrite Off
Might be needed, might not.

simple bloom
#

Okay not moment of truth, I have to restart because my AssetDatabase is stuck in editing mode again and won't reimport

short tiger
#

There's no quick way to test this on one asset at a time?

simple bloom
#

Not without rewriting the code that pulls the meshes from source to only grab one

#

Okay, good news, the normal map is working!

#

Bad news: I forgot to check to make sure it was only applied to the normal map negativeman

image.png
#

But that's an easy fix

short tiger
#

Also, I don't know if the normal maps you're working with can ever be encoded differently than DXTnm. It's a PC only format, so other formats are used for mobile and etc.

simple bloom
#

That should be fine, I don't need to support other platforms

#

My god it's finally over

it looks a tad pale so may need srgb correction

Hola,
I'm working with Unity and nvim, and it seems my scripts aren't compiling automatically on save.
This is fine in my eyes, I wrote a little Editor script that is supposed to request Script Compilation.


using UnityEditor;
using UnityEditor.Compilation;
using UnityEngine;

// Adds a hotkey to (re)compile scripts.
// Useful when Unity doesn't recompile scripts automatically.
// (This can happen when using external code editors like neovim)
public static class ScriptCompilationHotkey
{
   [MenuItem("Compile/Force Script Compilation #r")] // #r adds shift+r as the hotkey
   private static void ForceRecompile()
   {
      Debug.Log("Forcing script compilation...");
      CompilationPipeline.RequestScriptCompilation();
   }
}

However, it only seems to work sporadically??
Sometimes it triggers recompilation, sometimes it just shows the debug log?
Anyone who knows what may cause this?

surreal girder
crimson cobalt

#

well visual studio has functionality to make the editor recompile early it seems but id expect the "normal way" to work...

yeah is it maybe not picking up the changes on the filesystem for some reason? if you select the script in editor, see if you can see if your changes show up in the inspector

#

Is 'directory monitoring' off?

surreal girder
#

Preferences > Asset pipeline

crimson cobalt
#

yeah it is

#

it's fine if it doesn't automatically refresh, it's just that I can't get my editor script to recompile manually work consistently.

surreal girder
#

if a script file is re imported it should trigger recompilation then. But the function you call should too...

crimson cobalt
#

To my understanding it should recompile when I call either AssetDatabase.Refresh() or CompilationPipeline.RequestScriptCompilation();

surreal girder
#

you dont disable auto asset database refreshing anywhere do you? via AssetDatabase.DisallowAutoRefresh()

crimson cobalt
surreal girder
#

probably some dumb linux bug then if its not refreshing automatically (and is enabled)

dusk portal
#

it's been a while since i tried it on linux but in my experience the file change monitoring in the windows editor does work better, so my suspicion would be it's not seeing the changes to recompile them until you manually reimport

#

i guess your script could just reimport your scripts folder instead if that works?

crimson cobalt
#

hmm yeah maybe i could just click reimport manually i guess

surreal girder
#

this should work from code in some form so something must be broken or bugged

dusk portal
#

you should be able to do AssetDatabase.ImportAsset on a whole folder iirc, that should be like clicking "reimport" in the editor context menu

I really wish there was a way to create editor extensions at the editor level rather than importing it into every single project.

safe sorrel
#

you could, nominally, edit your project templates

pure siren
pure siren
#

And if it is a github editor package, it is almost worse because you constantly have to have manifest / packages-lock excluded.

Then you get to a point where you need to add a runtime package to the project and have to do this dance where you remove it from the manifest just to commit, then re add it to the manifest after and exclude it all over again.

safe sorrel
pure siren
safe sorrel
#

I see now. I thought the issue was just that you had to import a package into every project that uses it (which seemed like an odd complaint!)

pure siren
#

Like basically one that is attached to my install

#

and can be used by every project because it is just a "pure" extension to the editor

#

I know this can kind of be achieved with symlinks but that has its own drawbacks like still having to create a symlink in every project, plus these:

  • Assets/[Folder] is a symbolic link. Using symlinks in Unity projects may cause your project to become corrupted if you create multiple references to the same asset, use recursive symlinks or use symlinks to share assets between projects used with different versions of Unity. Make sure you know what you are doing.

  • Disabling directory monitoring for current editor session. Found Symlinks in project which cannot be used with directory monitoring. Directory monitoring settings can be changed in preferences.

How can I check if a Field is valid to be set in a VisualElement property field?

#

I create a VisualElement property Field like

propertyField = new PropertyField()
{
    label = nameReady,
    bindingPath = field.Name
};
extensionContainer.Add(propertyField);
#

Once Bind is called, it will add the necessary visual elements under, for example, if it's a float it will add a FloatField under PropertyField

#

However if it's not valid, lets say a Event, it doesn't add anything under it

#

Having a FieldInfo, is it possible to know if the FieldType will be valid for the property field to have data?

Does anyone know how much spacing is applied here? I tried just using indent level, but that applies too much space.

image.png
#

Sorry not the height, bad arrow on my part, the horizontal space between the left pane and the labels

#

It seems like it's 10.

I was wondering if there was a property to read from for this margin, in case it ever changes in the future, but doesn't look like there is.

#

Looking at the source, it seems to be defined in built in editor resources and not exposed as a property.

hot quarry
#

15-20 is typical

#

indented subcats double that.. so 30-40

pure siren
#

10 seems like the right value to make it line up with the title of the preferences page, I just wish they exposed this so custom preferences pages could use it. If they ever decide to change it, then I'll have to update it manually 😔

#

If you really pay attention, none of the preferences pages have consistent margin lol

#

So I guess it's whatever

#

What? The page in the screenshot is the built in general preferences window, so how would I even do that?

hot quarry
#

real quick since we're talkin about spacing..
is there a way to lock the hiearchy width?

pure siren
hot quarry
#

ya.. the icons on the right are editor scripting

#

i just gave up after i got the spacing on the right finished.. figured id go ahead and clean it up

#

and force the hiearchy to be so wide so teh icons dont cut into the text

pure siren
#

I don't think so, because the window size is up to the user since it is a dockable window

hot quarry
#

ahh you're right..

pure siren
#

You can try setting min width, but not sure if that would work

hot quarry
#

it may work.. as there already appears to be some limit

#

100 or so pixels looks like

pure siren
#

I guess I won't be bothered to be consistent with the margin in my custom preferences page since Unity themselves can't even be bothered to be consistent in their own pages.

hot quarry
#

as long as ur consistent within your system ur 💯 correct to not be bothered

#

I mean yeah, some of those preferences pages have been around for a long time and basically legacy at this point. So I get it, but damn like it wouldn't be that hard to update them to have consistent margins.

#

Lmfao hard coded

#

that explains a lot

#

Yeah I know, I appreciate it!

pure siren
#

Why would calling EditorGUILayout.Space() in between EditorGUILayout.BeginVertical() and EditorGUILayout.EndVertical() cause the horizontal padding to change?

#

If I don't call space, then there is zero horizontal padding. When I do call it, it adds some horizontal padding to the vertical layout.

#

See line 45

I knew about the UIElements debugger, but I didn't know IMGUI had a debugger lol. I will investigate more tomorrow morning with that then, ty!

Also you can look at the source code (pinned to this channel) and see what they did

#

the preferences window styles suck and and are hacky

vague portal
#

~cross posting because i used the wrong

pure siren
#

For whatever reason by omitting the space call it leaves left, right, and top margins which shifts it left.

When I add the space call, it zeros out those margins and doesn't shift.

#

Interestingly, calling GUILayout.Space() instead of EditorGUILayout.Space() does not have the same effect and the margins remain

pure siren
#

I think it is because GUILayout.Space() has this which EditorGUILayout.Space() does not.

if (Event.current.type == EventType.Layout)
{
    GUILayoutUtility.current.topLevel.entries[GUILayoutUtility.current.topLevel.entries.Count - 1].consideredForMargin = false;
}
#

Maybe it is intentional though, but I find it strange.

#

Description says use for horizontal layout, so okay maybe it is intentional. Oh wait, proceeds to show it used in vertical layout 🤦‍♂️

waxen sandal
#

It says to use the width parameter for horizontal, doesn't say anything about using the method for vertical layout

pure siren

And uses that parameter for both the width and height of the rect

Class I stole from core render pipeline package.

internal class SettingsProviderGUIScope : GUI.Scope
{
    float m_LabelWidth;
    public SettingsProviderGUIScope(int offset = 10)
    {
        m_LabelWidth = EditorGUIUtility.labelWidth;
        EditorGUIUtility.labelWidth = 251;
        GUILayout.BeginHorizontal();
        GUILayout.Space(offset);
        GUILayout.BeginVertical();

I just realized, they are calling GUILayout methods in this class lol and not the editor ones. Why do the editor ones even exist if they aren't going to use them in their own editor code?

The docs don't really explain what the differences are.

Generally you would use GUILayout for pretty much everything and EditorGUILayout for some niche features that GUILayout doesn't have (in editor scripts)

surreal girder

I use editor gui layout for custom editor windows as it's easier to use the horizontal/vertical and scroll layouts

chilly vault
#

hey sorry, didn't realise this channel existed so i'm moving this question over

#

ive been told GUILayout doesn't work in propertydrawers so im currently working on replacing that to see if it fixes the issue

#

that hasn't seemed to work @real spindle

#

here's a curveball though:
if i edit the PassageHandlerDrawer and then try to change PassageName...it works. it lets me change the name. but after that, i can no longer change the name again

#

so i guess the drawer is being reloaded here which lets me modify the field and then the issue appears again

#

im doing some more testing to figure out the cause and i think it might actually be caused by a SceneHandler being serialized inside a PassageHandler

#

if i make a SceneHandler and add a passage, I can change the name whenever i want

image.png image.png
#

if i make a second SceneHandler and attach it to the first PassageHandler, i can still edit the name freely

image.png image.png
#

but as soon as I add the first SceneHandler to a PassageHandler in another SceneHandler object, i can no longer edit the fields in the first SceneHandler

image.png
#

yeah i think this is the issue. i just made a new SceneHandler, added a passage and gave it a name, and then added its own SceneHandler as the target. and i could no longer modify the passage name.

@chilly vault I skimmed it but I am almost positive the issue is that you are applying the modified properties and updating it.

#

The Editor for the UnityEngine.Object handles the applying and updating

chilly vault
gloomy chasm
#

Correct

chilly vault
#

i also removed any GUILayout lines since propertydrawer can't use them. also didn't fix the issue

gloomy chasm
#

Did you override the GetPropertyHeight method?

#

That is required as well

chilly vault
#

uhh i didn't

chilly vault
gloomy chasm
#

The height that the property requires to be drawn. Typically it is

return EditorGUIUtility.singleLineHeight * fieldCount + EditorGUIUtility.standardVerticalSpacing * (fieldCount - 1);
#

With you specifying the field count. And that being how many input fields tall the property is.

chilly vault
#

gotcha

#

it kinda messed up the UI but ill figure that out later

image.png
#

it hasn't solved the editing issue

#

still cant change the passage name

safe sorrel
#

oh wait, this is a property drawer

#

misread that as PropertyField

How to do world to screen in the editor?

surreal girder
#

you can get the current scene view camera so it should be doable as normal

How to do it?

SceneView.currentDrawingSceneView.camera?

Hello there.
I'm trying to create a tool script to help me scale objects more accurately for human sizes. It's supposed to render a hand and a human next to the object that you are changing the scale of.

Rendering the hand works just fine, but using the exact same code it just doesn't do it for the human model. I can't seem to figure out why this is not working, or what could possibly be wrong with my human fbx.

#

Here's the code:

using System;
using System.Collections;
using System.Collections.Generic;
using Unity.Mathematics;
using UnityEngine;
using UnityEditor;
using UnityEditor.EditorTools;

[CustomEditor(typeof(MeshRenderer))]
public class ScaleReferenceTool : Editor
{
    private MeshRenderer meshRenderer;
    private static Mesh handMesh;
    private static Mesh humanMesh;
    private static Material ghostMaterial;
    
    private void OnEnable()
    {
        meshRenderer = target as MeshRenderer;
        if (handMesh == null)
        {
            handMesh = AssetDatabase.LoadAssetAtPath<Mesh>("Assets/ToolResources/RightHand.fbx");
        }
        if (humanMesh == null)
        {
            humanMesh = AssetDatabase.LoadAssetAtPath<Mesh>("Assets/ToolResources/Human.fbx");
        }
        if (ghostMaterial == null)
        {
            ghostMaterial = AssetDatabase.LoadAssetAtPath<Material>("Assets/ToolResources/ScaleReferenceMaterial.mat");
        }
    }
    
    private void OnSceneGUI()
    {
        if (Tools.current != Tool.Scale) return;
        if (meshRenderer == null || handMesh == null || humanMesh == null) return;
        if (ghostMaterial == null) return;

        Vector3 boundsExtents = meshRenderer.bounds.extents;
        
        ghostMaterial.SetPass(0);
        Graphics.DrawMeshNow(handMesh, meshRenderer.transform.position + new Vector3(boundsExtents.x+0.05f,0,0), Quaternion.Euler(0, 0, -90));
        //ghostMaterial.SetPass(0);
        //Graphics.DrawMeshNow(humanMesh, meshRenderer.transform.position, quaternion.identity);
    }

}
#

and these are the assets:

#

expected result:

#

Do you guys have any idea what could be my problem?

waxen sandal
#

You never described the result you're getting, only that it doesn't work

verbal heath
#

On the screenshot, you can see the hand drawing just fine, but the human model just doesn't appear. I don't know how to debug this as I don't think I can put a break point in an editor script.

waxen sandal
#

You can debug editor code just fine

#

Anyways, would be good to isolate things, if you render with a 2 sided material, does it show? Does it have a weird pivot and it's rendering offscreen somewhere?

verbal heath
waxen sandal
#

You've verified that it manages to load from that path?

verbal heath
#

plus I didn't type the path, I copied it from the editor

#

did a debug.log on it, unity says it's a mesh

waxen sandal
#

Are there multiple meshes in your fbx?

#

I forgot whether load just gets the first one or a compound thing

verbal heath
#

Should be just one model. But just to make sure, earlier I went back to Blender and deleted everything, even the vertex groups. It is just a mesh, with applied transforms and no material. And no camera or light was exported with it.

#

The import settings are the same as for the hand.

surreal girder
#

hopefully changing the import scale will fix it

feeling a bit stupid. I know ShootProjectileActionView is running, but the propertyfield doesn't show up

Screenshot_2025-02-07_144606.png Screenshot_2025-02-07_144555.png Screenshot_2025-02-07_144539.png Screenshot_2025-02-07_144617.png
#

its public

#

ShootPattern is serializable

#

idk why its not showing

#

no console errors

#

I can't breakpoint the ShootPatternDrawer for some reason

#

(also this was working before, idk what changed)

gloomy chasm
#

Where is ShootProjectileAction being used/serialized?

#

My first guess @wanton arrow would be that it is a polymorphic field that is not marked with [SerializeReference]

wanton arrow
#

it is being marked with that, but how would the prefab show up then?

#

all the other types work as well

gloomy chasm
#

What is Getter<>?

wanton arrow
#

it gets a value

#

either a constant, variable, or expression

wanton arrow
gloomy chasm
#

I mean can you share the definition of it?

wanton arrow
#

im confused why thats relevant

#

but sure

gloomy chasm
#

Because ShootPattern is the only one not showing, and the only field it has is the Getter so I was wondering if there was just no serialized data to show

wanton arrow
#

it also has a type enum

#

it shows in debug mode as well

#

but not in normal mode even if I remove the "custom property field" thing from the drawer

#

so im assuming it has nothing to do with that file

gloomy chasm
#

Well I don't have all that info, so I am just making educated guesses 😛

wanton arrow
#

ik

#

im pretty sure the only thing I changed was making the stateactions polymorphic

#

and moving it to a different class

#

but idk how that makes this occur

#

its annoying I dont even get an error

gloomy chasm
#

So is your "testing" message being logged?

wanton arrow
#

nope

gloomy chasm
#

Where is the StateActionView being used

#

oh

#

duh

wanton arrow
#

i beleive only to be inherited from

gloomy chasm
#

You are trying to get a property called "shootPattern" when the property is just "pattern"

wanton arrow
#

the correct stateactionview is being loaded

#

oh.

#

why doesn't unity tell me that

gloomy chasm
#

Been there done that. Since you are just using public fields, I would use nameof instead.

wanton arrow
#

I think i never considered that bc I thought It is supposed to give you an error??

#

I blame unitys api for my mistakes

gloomy chasm
#

Hahaha, it has benefits to the way it works. But I agree it for sure also has drawbacks

surreal girder
#

im just wondering why an object cast is needed before the cast to T 🤔

wanton arrow
#

in what world would you not want it to error when it can't find the correct property

wanton arrow
gloomy chasm
#

But yeah, I do recommend using nameof if you are just going to use public fields.

wanton arrow
#

as far as I can tell it just is

wanton arrow
#

never heard of that

gloomy chasm
surreal girder
#

nameof(My.thing)

wanton arrow
surreal girder
#

oh shit i see, i wonder if you can do an unsafe re interpret

wanton arrow
#

after using c++ I kinda dislike how C# generic types work but ik they have other nice benefits

#

it would be nice to be able to just constexpr the type

surreal girder
#

cus of the old c# ver we cant do const string interpolation either 😭

wanton arrow
#

const string interpolation?

surreal girder
#

like const string THING = $"{someVar}_foobar";

#

presuming someVar is const too

wanton arrow
#

ohh

#

lame

surreal girder
#

when we get .net core clr in 17 years it will be good

peak bloom
#

at least on CLR.... lets just pray Mono does that too

surreal girder
#

Yea I'm sure when the generic function is generated for the type it will be optimised but I don't know how good old mono is

peak bloom
#

incase some nerds confused what recognized here means 🤤 (T)(object)SomeTypeT is a common pattern used since ancient times and known to be optimized away

surreal girder
#

modern c# or cpp or rust I would expect to optimise this well (but there we can use reinterpret_cast<>() or similar) in template/generic functions but unity I don't trust 🤔

#

i wish i could find it but i read a good blog post a bit ago that showcased some pretty shit IL code gen that was giving this person some bad performance with ui toolkit

peak bloom
#

uh, why rinterprate cast?
most of these come with unsafe price in c#

ref byte tref = ref Unsafe.As<TFrom, byte>(ref something);
var into = Unsafe.ReadUnaligned<T>(ref tref);

yeah, doesn't make any sense for such simple thing and might not be faster

#

let the compiler do it's job 🙂

peak bloom
surreal girder
peak bloom
#

look up for polyfill in c#

I just noticed in the console window in the editor there is an option to use a monospace font. Does anyone know how to get a handle to this font so I can use it in my own editor window? I've taken a look through things like EditorStyles but no luck finding anything so far.

Hey, I had an issue a couple of days ago and got super confused so I've done some testing and I have a more clear idea of the problem now.

I have a SceneHandler scriptable object, a PassageHandler scriptable object, and some editor/property drawer scripts for them.

SceneHandler: https://paste.ofcode.org/XYGF2HaRgxfRGcNbNprGwu
PassageHandler: https://paste.ofcode.org/xzz8LHB5Y8y59dZ8DGnKRW
SceneHandlerEditor: https://paste.ofcode.org/KBWNpLUDFYJuvdyxbDmthD
PassageHandlerDrawer: https://paste.ofcode.org/MbwKTgVsRWgqY6w2QrirPG

The PassageHandlers are created and displayed in a SceneHandler. They have a passage name, a targeted scene handler, and can then select from a list of passage names from that targeted scene handler as their target passage.

If I create two SceneHandlers and create a PassageHandler on each, I can edit the name fields to give them custom passage names, I can select a target SceneHandler for both PassageHandlers, and I can set the target passage for both to the other passage on the other scene. (So Passage1 on Scene1Handler connects to Passage2 on Scene2Handler and vice versa).

If I then add another PassageHandler to one of the SceneHandlers, I can't edit any of the fields on any of the PassageHandlers (on any SceneHandler). For example, I can start writing in the passage name field but as soon as I click off the inspector panel, the changes aren't saved.

However...if I edit any file (meaning the Unity project is reloaded), I can edit anything I want on the currently-open SceneHandler and it saves the changes. As soon as I click off the SceneHandler, I go back to not being able to make edits to the PassageHandlers.

image.png
#

While testing whether or not the edit changes were being saved, I noticed that in PassageHandlerDrawer, after the line,

EditorGUI.PropertyField(rect, passageName);```
reading passageName.stringValue returns the **correct** new passage name for one frame and then immediately goes back to whatever the passage name was before the field edit.

I'm pretty new to Unity Editor stuff so I hope this is enough info on the problem. I've been told that I can't use EditorGUILayout in a PropertyDrawer but...it seems to be working fine right now and changing the code to replace any instances of EditorGUILayout didn't fix the issue.
gloomy chasm
#

You commented out the important part of the code 😛

#

What is the result you are trying to get?

#

Well actualy it isn't that important I guess

#

Two options, one, check if the instance id is the same as the first GameObject in the Scene. And only apply the scale if it is. Two is to use harmony and inject the scaling code in to the hierarchy window before it is draw.

gloomy chasm
#

The first because it does it draw order

visual stag
#

Also ScaleAroundPivot modifies GUI.matrix

#

so you're doing that repeatedly, not once. It never gets reset

gloomy chasm
visual stag
#

you'll have to find a way to reset the matrix at the end. This is all just hacking things, so there's not going to be an easy way to do this

#

and I'd honestly be surprised if you got it to work properly

gloomy chasm
#

That is because changing the matirx is just changing how it is rendering, now the actual layout info

surreal girder
chilly vault
# surreal girder Can I ask what you hope to achieve with PassageHandler having ``[SerializeRefere...

each PassageHandler needs to know about all of the PassageHandlers on its targeted SceneHandler to create a connection between two PassageHandlers.
the goal is to have 2 scenes with a passage object in each. each passage links to a PassageHandler on the correct SceneHandler and this is used to spawn the player at the correct place in the next scene.

So the player interacts with a Left Passage game object in Scene 1, the Left Passage game object connects to a Left Passage PassageHandler on Scene1Handler, that PassageHandler connects to a Right Passage PassageHandler on Scene2Handler, and that PassageHandler connects to a Right Passage game object which contains logic to spawn the player

#

SetPassageList() is called from SceneHandlerEditor when the SceneHandler's "Passages" list contains at least one PassageHandler. the function should just populate TargetScenePassageNames with the Passage Name of each PassageHandler on the TargetSceneHandler

#

and then TargetScenePassageNames is used by the property drawer to display a Popup of all the names

surreal girder
#

But why are these all Serialized and not just the index

chilly vault
#

oh weird. i dont actually use TargetScenePassages anywhere from the looks of it

#

only here: cs TargetScenePassages = TargetSceneHandler.Passages which could easily be removed

#

oh my god i think that fixed it

#

aaaaaaa heheeheh

#

works flawlessly now

#

@surreal girder thank you so much! ive been pulling my hair out for days over this and it turns out i just needed to comment out 2 lines hahaha

#

do you know why that was causing the issue?

I would probably give EditorAttributes a go first.
