#

first line is just reserving a space

#

it's a solution, but I'm sure any other viable solution is probably going to better

#

if you can figure out what those other solutions are

ivory fulcrum Dec 27, 2020, 1:45 AM

#

What is spriteSerial?

#

Because that actually is how I want the Object Field to look for each letter but with a Label underneath

naive canopy Dec 27, 2020, 1:47 AM

#

SerializedProperty spriteNameSerial = serializedObject.FindProperty("SpriteName");

ivory fulcrum Dec 27, 2020, 1:47 AM

#

hmm and SpriteName is the texture2D object?

naive canopy Dec 27, 2020, 1:47 AM

#

yeah, actually it's a sprite, I forgot to change it

ivory fulcrum Dec 27, 2020, 1:48 AM

#

Does it have to be a sprite?

#

or does it not matter?

naive canopy Dec 27, 2020, 1:48 AM

#

I don't think it maters

#

texture2D works too, but in my case I'm working with sprites

#

so when I select to change one of them, it shows me sprites instead of texture2d's

ivory fulcrum Dec 27, 2020, 1:49 AM

#

Ok.

#

I'm working with Textures since I only need the texture saved

naive canopy Dec 27, 2020, 1:49 AM

#

hmm

#

you know

ivory fulcrum Dec 27, 2020, 1:49 AM

#

I can generate a sprite automatically from the texture at will using Sprite.Create(tex, new Rect(0, 0, tex.width, tex.height), new Vector2(0.5f, 0.5f))

naive canopy Dec 27, 2020, 1:50 AM

#

if you have your object that contains a char and a texture2d

#

you should be able to pull out the properties the same way

#

In my case I'm using spritesheets

#

since you can iterate through a serialized list, you can pull out each serializedobject, and from then get both of the serialized properties

#

and do whatever with them

#

for your List<Letters>

ivory fulcrum Dec 27, 2020, 1:52 AM

#

That's what I'm trying to do

#

I'm also wondering if I should be using "BeginProperty" to define the editor instead of PropertyField

naive canopy Dec 27, 2020, 1:55 AM

#

not sure there

#

you might want to store the characters as strings

#

so you can use stringvalue on the serialized property

#

you might also be able to just cast the objectReferenceValue as char, but I don't know if that will work

ivory fulcrum Dec 27, 2020, 1:57 AM

#

Right now what I'm running into is I can get the Object of Letter, but...

#

Although, I'm getting a NullReferenceException

naive canopy Dec 27, 2020, 1:58 AM

#

can you post your code somewhere

ivory fulcrum Dec 27, 2020, 1:59 AM

#

Yeah, hang on. There's some discarded code commented out in there too that might give you an idea of some things I've tried.

naive canopy Dec 27, 2020, 2:00 AM

#

yeah about half of my code is that lol

ivory fulcrum Dec 27, 2020, 2:01 AM

https://repl.it/@GinoMan/Letter-Minigame#main.cs

repl.it

GinoMan

Letter Minigame

A C# repl by GinoMan

#

It's also by no means complete

#

But hopefully it will give some context

#

CustomUI is a Naninovel thing

#

And it just made sense to me to subclass it and add on my values for its editor

#

Instead of making a "new script"

#

Especially since I may need to reference those UI values in Naninovel

#

Not sure yet. I might separate it out later on

#

the code under "testing code" is me playing with Intellisense

#

to find out what I can do with what the classes provide

#

Which tends to be how I use C#

#

Otherwise I'd be pouring over the documentation and it would take a lot longer for me to write the code

#

I could probably break LetterList out of the LetterMinigame class so it's its own class

naive canopy Dec 27, 2020, 2:06 AM

#

hmmm

ivory fulcrum Dec 27, 2020, 2:10 AM

#

Anything stick out?

naive canopy Dec 27, 2020, 2:10 AM

#

Just wrapping my head around it, you write a bit differently than I do

#

I figured you were using List<Letter> instead of wrapping it around another class

ivory fulcrum Dec 27, 2020, 2:11 AM

#

That probably comes from the other languages I've worked with

#

I have the other class because a lot of lookups happen through type

naive canopy Dec 27, 2020, 2:12 AM

#

Letters isn't a property of LetterList

ivory fulcrum Dec 27, 2020, 2:12 AM

#

Where "I can find this for you" or "I can do these replacements, but I want to replace an entire type's editor" or "I want to find that data by 'type'"

#

I don't want ALL lists of Letters or lists of Texture2D to be replaced with my editor

#

or find all the textures that are in lists

#

So I wrapped the type so that only wrapped types get found or get replaced

#

idk, maybe that's a faulty assumption on my part about how it works

#

but that's my understanding so far

#

Letters? Letters is an object of LetterList in my LetterMinigame class

naive canopy Dec 27, 2020, 2:14 AM

#

var list = property.FindPropertyRelative("Letters");

ivory fulcrum Dec 27, 2020, 2:15 AM

#

hmmm

#

wait... so I should be doing "GetArrayElementAtIndex, and then getting the properties of that?

naive canopy Dec 27, 2020, 2:17 AM

#

I meant more that Letters is not the property of any class

ivory fulcrum Dec 27, 2020, 2:17 AM

#

😮 because it replaces LetterList..... not the whole Minigame!

#

OHHHHHH

#

Ooof

naive canopy Dec 27, 2020, 2:18 AM

#

yeah you will likely have to use GetArrayElementAtIndex or some other array accessor

#

either against the serializedobject or the serializedproperty

ivory fulcrum Dec 27, 2020, 2:19 AM

#

EditorGUI.PropertyField(rect, property.GetArrayElementAtIndex(index));

#

right?

naive canopy Dec 27, 2020, 2:19 AM

#

so you need to pick an object out of the array

#

and then properties out of that object

#

the editor doesn't like anything except primitives and things that derive from the normal unity objects (sprites/texture)

#

does that make sense?

ivory fulcrum Dec 27, 2020, 2:25 AM

#

yes

#

hmmm

#

So if there should always be 26 elements, should the ctor for LetterList (I'd have to write one) create those?

#

Because it's complaining that the elements are "null" which makes sense if the elements haven't been created yet

naive canopy Dec 27, 2020, 2:27 AM

#

right

#

Not sure how you are planning on storing it

#

I'm sure someone else might be able to help you more, I'm pretty new to this stuff

ivory fulcrum Dec 27, 2020, 2:32 AM

#

That makes 2 of us

#

LOL

#

Oh, if you refresh the link I gave you, it should have some new code

#

Still a bunch of nulls. I'll keep working on it

naive canopy Dec 27, 2020, 2:36 AM

#

you should attach to it

#

and debug it from there

ivory fulcrum Dec 27, 2020, 2:40 AM

#

I've... never done that before

#

I've always debugged by guess and check

naive canopy Dec 27, 2020, 2:51 AM

#

oh..

ivory fulcrum Dec 27, 2020, 2:51 AM

#

Well... that's not entirely true, but I've not really used the debugger with Unity

#

Well.... here goes nothing

#

I just pressed the "attach to unity" button

naive canopy Dec 27, 2020, 2:54 AM

#

yep

#

and then you put in some breakpoints right before hit horks

#

and check your variables

ivory fulcrum Dec 27, 2020, 2:56 AM

#

Ok. I'll try it

severe python Dec 27, 2020, 3:14 AM

#

is there a known solution or strategy for virtualizing controls in a scrollview?

gloomy chasm Dec 27, 2020, 3:24 AM

#

@severe python What do you mean?

ivory fulcrum Dec 27, 2020, 3:41 AM

#

Shouldn't property.serializedObject.targetObject be of the type that CustomPropertyDrawer takes as its argument?

gloomy chasm Dec 27, 2020, 3:49 AM

#

ivory fulcrum Shouldn't property.serializedObject.targetObject be of the type that CustomPrope...

Nope, it is actually the UnityEngine.Object that the property is of.
So if you had a public class MyCustomData {}
and

public class MyMonoBehavior : MonoBehavior
{
  public MyCustomData myData;
}

And had a CustomPropertyDrawer for MyCustomData, then the property.serializedObject.targetObject would actually return the instance of MyMonoBehavior.

ivory fulcrum Dec 27, 2020, 3:56 AM

#

So what I want then is

var target = (LetterMinigame)property.serializedObject.targetObject;
var list = target.Letters;

#

And then I can make sure that Letters is instantiated, has the 26 default elements, and then can construct the EditorGUI.PropertyField's

gloomy chasm Dec 27, 2020, 4:01 AM

#

ivory fulcrum And then I can make sure that Letters is instantiated, has the 26 default elemen...

I don't know what you are doing exactly so I really couldn't say. I can say that if you get the list as a SerializedProperty, it will never be null. Unity's serialization does not support null.

ivory fulcrum Dec 27, 2020, 4:01 AM

#

Yes but unfortunately List<T> does

gloomy chasm Dec 27, 2020, 4:01 AM

#

Why access the list directly?

ivory fulcrum Dec 27, 2020, 4:02 AM

#

Because that's where my NullReferenceExceptions seem to be coming from.

#

Trying to create the PropertyField is where it chokes because the index doesn't yet exist

#

Even though in the ctor for the List<T> derived type, it constructs 26 elements with default values

gloomy chasm Dec 27, 2020, 4:04 AM

#

You shouldn't be getting a NullRefException from SerializedProperty. If you want to share the code through Hastebin or something I could take a look at it if you want.

#

Na, this is fine.

onyx harness Dec 27, 2020, 4:14 AM

#

You are mixing both worlds (C++ & C#), you are straightforwarding a headache

#

Either stick to Serialized stuff (C++) only, or use the List (C#) and stay away from SerializedObject/Property.

#

To be fair, you can toy with both worlds, but you need to have solid understanding of how serialization works.

gloomy chasm Dec 27, 2020, 4:17 AM

#

@ivory fulcrum One thing I notice is that you are deriving Letter from UnityEngine.Object, you con't actually do that. Anything derived from that requires something on the C++ side as well (If memory serves)

onyx harness Dec 27, 2020, 4:18 AM

#

To give you an easy debug, use the iterator (SerializedProperty) of SerializedObject, and print the propertyPath of every iterations using Next(true).

ivory fulcrum Dec 27, 2020, 4:21 AM

#

Ok. I read that deriving from that is a way to allow serialization, but I didn't know if it was necessary

#

It doesn't have to be and I thought that might be part of my problem.

onyx harness Dec 27, 2020, 4:21 AM

#

Remove it, simple class with attribute Serializable can be serialized

#

When you derive from Object, it means you can physically exist in the Project as an asset.

ivory fulcrum Dec 27, 2020, 4:22 AM

#

ahh. Ok

ivory fulcrum Dec 27, 2020, 4:37 AM

#

Mikilo: Is that the only reason you said I was mixing both worlds?

#

Also. What kind of nonsense is it that you cannot use a "white texture" or any other default texture in a constructor or serializer?

#

You can't use null, nulls aren't allowed. Ok, I'll use a default white texture. NOPE! that's not allowed either.... well frick!

onyx harness Dec 27, 2020, 4:50 AM

#

There is a high chance that the white texture is generated at runtime and can't be saved, but that assumption needs a confirmation

onyx harness Dec 27, 2020, 4:51 AM

#

ivory fulcrum Mikilo: Is that the only reason you said I was mixing both worlds?

You are using SerializedProperty (C++) and the target directly (C#)

onyx harness Dec 27, 2020, 4:52 AM

#

ivory fulcrum You can't use null, nulls aren't allowed. Ok, I'll use a default white texture. ...

You can use ISerializableCallbackReceiver to verify deserialization

ivory fulcrum Dec 27, 2020, 4:54 AM

#

I'm not even talking about the deserialization, I just mean the default texture unless assigned

#

Also it all looks like C# to me

#

I haven't used C++ in years

onyx harness Dec 27, 2020, 4:56 AM

#

This implies 2 things.
When you create it the first time, the white texture 'might' be correctly assigned.
But when you reload (recompile, loading from disk, restart Unity) the texture assignation will probably be gone. Hence the deserialization check

ivory fulcrum Dec 27, 2020, 4:56 AM

#

when I say "nope" I mean the editor throws exceptions all over the place about it

#

It's not that it "doesn't work" in the sense of You get your editor but nothing saves, but rather that it breaks completely

#

I can live with "nothing saves".

onyx harness Dec 27, 2020, 4:57 AM

#

ivory fulcrum Also it all looks like C# to me

It is all C#, but when you toy with SerializedObject, the data that is being used and altered is on the C++ side

ivory fulcrum Dec 27, 2020, 4:58 AM

#

Everything I've seen says to use SerializedObject and SerializedProperty

onyx harness Dec 27, 2020, 4:59 AM

#

Which is good, but then don't use target in the middle (your list used in the loop)

#

This is where you start mixing both

ivory fulcrum Dec 27, 2020, 4:59 AM

#

where I got the property.serializedObject.targetObject was from the debugger telling me where it was getting these null references from

#

or seemingly where

#

Because it creates an object, and then the SerializedProperty has another copy under that nesting that has null entries

#

Maybe I was misinterpreting what I was seeing in the debugger but that was what was "null" and then after that I got the Null reference exceptions

ivory fulcrum Dec 27, 2020, 5:28 AM

#

OMG who designs this!?

@gloomy chasm i meant that rendering 1000 rows in imgui is expensive. I'd like to virtualize that result in a sense. I figured out how to do it though

Its Not actually virtualization

gloomy chasm Dec 27, 2020, 3:10 PM

#

oh, well glad you figured it out!

ivory fulcrum Dec 27, 2020, 4:20 PM

#

Wait... am I right in thinking that events in the Inspector call "OnGUI" when they happen?

#

.... It's an update function

#

No wonder this is so hard to wrap my head around. They have an update function to produce the gui AND handle events, etc, and on top of that use a ton of global state.

#

And layout is all done by manually calculated Rects.

naive canopy Dec 27, 2020, 6:50 PM

#

OnEnable() only happens once when I click on something right?

ivory fulcrum Dec 27, 2020, 8:52 PM

So I refactored to get rid of the LetterList class..... (Ok, not completely got rid of, I turned it into a static extension method class) and now my custom GUI isn't even being used.

#

PropertyDrawer applies on each element of a collection. Not the collection itself.

ivory fulcrum Dec 27, 2020, 10:50 PM

Ok. So I need a PropertyDrawer to replace Letter, not List<Letter>

How do I make it so that the List is Expanded?

heady jungle Dec 28, 2020, 5:45 PM

#

Never had this problem before, but this small bit of code (for a custom inspector) causes the editor to crawl when in play mode:

    public override void OnInspectorGUI()
    {
        serializedObject.Update();
        EditorGUILayout.PropertyField(green);
        if (green.boolValue)
        {
            contextButtons.InsertArrayElementAtIndex(0);
            EditorGUILayout.PropertyField(contextButtons.GetArrayElementAtIndex(0));
        }

Then again, I'm still unclear on exactly what to put where (as I'd guess that it's trying to apply the array parts constantly?)

waxen sandal Dec 28, 2020, 5:57 PM

#

Going to guess it's adding elements constantly

heady jungle Dec 28, 2020, 6:04 PM

#

Yea, would it be prudent to make a check to see if the bool value has changed since the last update, then based of that modify (or not) the array element?

Or should I just keep the array fixed at 5 (for predefined buttons) and use bool values to decide whether to display them or not?

gloomy chasm Dec 28, 2020, 6:07 PM

#

@heady jungle Yeah, as Navi said. As long as green is true, it will add an array element every time OnInspectorGUI is called (I think default is 20 times a second?)

#

=======
Got a question of my own. How do you make sure a custom field supports prefabs/overriding? I mean like show that it has been overridden, and have the context menu and stuff?

waxen sandal Dec 28, 2020, 6:24 PM

#

Use changecheck @heady jungle

#

I don't remember the conditions exactly but using serializedproperties for everything gets you quite far @gloomy chasm

heady jungle Dec 28, 2020, 6:25 PM

#

Merci, that is perfect 🙂

gloomy chasm Dec 28, 2020, 6:29 PM

#

@waxen sandal It functionally works okay. But there is no visual indication, and it is for a tree/hierarchy data structure so I want/need to handle the overriding in a custom way. But I haven't been able to find much on how to do it.

waxen sandal Dec 28, 2020, 6:54 PM

Also wrapping in begin/end property should do things

@violet veldt Unity does not support polymorphic serialization of UnityEngine.Objects, which includes interfaces. So no, not unless you do custom serialization and property drawer.

    // If it has, we can assume that it is no longer being drawn sense undoCalled is reset in OnGUI.

Yeah, that would probably be a good idea to return right away. In OnGUI _undoCalled is set to false at the end. So the only time in OnUndoPerformed that _undoCalled would be true, is if OnGUI was not called (Or if a Undo/Redo operation was called twice before OnGUI was called again). And the only reason it would not be called, would be if the PropertyDrawer was no longer in use.

Is this simple to do? And how?

Is there a way for those of us without deep pockets can get access to the source code for UnityEditor? Specifically, I'd like to extend SerializedProperty, SerializedPropertyType and the PropertyDrawer stuff. I'm not sure the best way to go about that without looking at the source.

You can C# extend, but not override the classes.

So you create a separate script that defines how the scriptableObject custom header is drawn in the SO? Is this just essentially overriding the header?

gloomy chasm Jan 1, 2021, 8:53 PM

#

@honest dune What is it that you are wanting exactly? In that tweet, what they are doing is have a custom attribute that they add to the fields in their script that makes it look like a header (or something else).
Is that what you want? Or are you wanting to be able to full customize the look of the inspector for a ScriptableObject? If that is the case, then you want to look at this: https://docs.unity3d.com/Manual/editor-CustomEditors.html

honest dune Jan 1, 2021, 8:57 PM

#

Uhh, I just want a header like that. I have a Skill SO but else than looking at my comments in the actual SO Script it can be a bit annoying to create new skills since I sometimes take a break and am not exactly sure what some attributes do, so I want to clarify that when you make a script.

#

Like this is literally all I want right now honestly, and I can use two Headers with an Order but the second header being the same size etc makes it a little bit jarring. I just don't wanna delve too much in custom attributes/customeditor since it's just a small clarity thing.

gloomy chasm Jan 1, 2021, 9:03 PM

#

honest dune Uhh, I just want a header like that. I have a Skill SO but else than looking at ...

Ah, then you do want the attributes then. Just so you know Unity has a couple of decorative attributes builtin that you can use.
There is [Header("My Header")],

[Tooltip("This a tool tip that will show up when hovering over the label of the field in the inspector")]

[Range(0, 1)] // Makes a numeric field a slider

[Space] // Puts a space between two fields

[HideInInspector] // makes it so the field does not show up in the inspector

[Multiline] // make a string be edited with a multi-line textfield.

[Min(0)] // make a float or int variable in a script be restricted to a specific minimum value.

There are more, but those are the most used ones.

#

You can see them all on the side here if you want to look at them https://docs.unity3d.com/ScriptReference/AddComponentMenu.html

Just note one thing, a DecoratorDrawer can only strictly draw GUI around the field.
PropertyDrawer can interact with the field.

honest dune Jan 1, 2021, 9:17 PM

#

and a DecoratorDrawer would be like the header?

onyx harness Jan 1, 2021, 9:18 PM

#

Exactly

honest dune Jan 1, 2021, 9:19 PM

#

So is it like Overriding? Like a customGUI or whatever edits the original Header one, so if I wanted like a two argument header with a sub like [Header("Main Header","Custom Description")] It'll edit the original script or w/e?

gloomy chasm Jan 1, 2021, 9:22 PM

#

honest dune So is it like Overriding? Like a customGUI or whatever edits the original Header...

You would need to make your own attribute. Also because you can't add parameters to a constructor.

honest dune Jan 1, 2021, 9:24 PM

#

Ah. So I'de essentially be making a new custom attribute that you like have to define via drawing in the inspector I guess

onyx harness Jan 1, 2021, 9:30 PM

#

honest dune So is it like Overriding? Like a customGUI or whatever edits the original Header...

If you want one particular GUI, yes you will have to implement your own.
If you need one small addition, remember that you can stack Decorators.
Use a Header for the big title, and use a SmallHeader for a small title.

honest dune Jan 1, 2021, 9:33 PM

#

So just make a smallHeader implementation and stack it with the regular one

If Header is enough, yep

I'm getting so confused by editor scripts. How do I get an enum (set IN the editor script) to appear and be editable?

[CustomEditor(typeof(ContextButton))]
Public class ContextButton_Editor : Editor{
  public Button_Enum buttonEnum;
  public override void OnInspectorGUI(){
    if (buttonEnum == Button_Enum.blue){
      //Draw stuff;
      }
  }
}```

#

The only way I can get it to show up is with EditorGUILayout.EnumFlagsField(buttonEnum); but that defaults to buttonEnum 0 and doesn't let me change it. All the examples I find assume that the enum if being called from the non-editor portion of the script

#

I was missing a cast: buttonEnum = (Button_Enum)EditorGUILayout.EnumFlagsField(buttonEnum);

@visual stag thanks. I figured out what went wrong. I had an initialization code that GetComponentsInChildren. And this works as long as the container parent is activeSelf during startup. I disable it so scene isn't cluttered, and as a result they weren't being registered...oddly enough, no NullReferenceExceptions where thrown either. Anyways, fixed it with GetComponentsInChildren(true).

So, I'm creating a custom inspector for one of my scripts, and, basically, I have somethin' like this:

public class MyScript : MonoBehaviour
{
  public bool shouldShow = true;
  public GameObject somePrefab;
}

[CustomEditor(typeof(MyScript))]
public class MyScriptEditor : Editor
{
  public override void OnInspectorGUI()
  {
    base.OnInspectorGUI();
    //...
  }
}

I want to hide somePrefab from the inspector if shouldShow is false.
I came across this solution (the "best answer"):
https://answers.unity.com/questions/192895/hideshow-properties-dynamically-in-inspector.html
Which is nice and all, but he's not calling base.OnInspectorGUI(). What this means is, every time I add a serialized/public field to MyScript, I may have to go into MyScriptEditor and add an extra line. This back-and-forth workflow sounds tedious.

#

My main question is:
is there a way for me to just call base.OnInspectorGUI, then find the serialized property by name and conditionally hide it?

#

e.g.,

public override void OnInspectorGUI()
{
  base.OnInspectorGUI();
  SerializedProperty shouldShow = serializedObject.FindProperty("shouldShow");
  SerializedProperty somePrefab = serializedObject.FindProperty("somePrefab");

  //the part below is what I want to be able to do:
  if(!shouldShow.boolValue){
    somePrefab.Hide();
  }
}

I am getting some strange behavior, perhaps I am not understanding something that's going on under the hood? I have a UI PlayerMenu that opens when the player presses "E" key. In the menu, there is an inventory section that has slots. The slots have children that are SetActive(false) by default.

In my code, if I "pickup" an item, those children become SetActive(true) even if the PlayerMenu is SetActive(false). I can confirm this in the inspector that the checkmark appears on the gameobject correctly. BUT, it is when I SetActive(true) the PlayerMenu, that those children get "reverted" back to their original state (which was SetActive(false))

Why does the parent gameobject keep revert the children back to their inactive states if it is activated? This I confirmed because if I start with the PlayerMenu in active state, then the script deacticates it on start, it doesn't have this behavior. But if I start it with it inactive, this occurs.

keen pumice Jan 4, 2021, 8:37 PM

#

@waxen sandal got it, just FYI: was a combo of changing stuff during an event OTHER than Layout, AND the fact that the serialized property function DeleteArrayElementAtIndex will set the element at the index to null, rather than actually delete the array element (only values that are already null, or not nullable, are deleted!)

#

@waxen sandal thanks for the help!

waxen sandal Jan 4, 2021, 8:37 PM

#

@keen pumice makes sense somewhat

#

@quaint zephyr you sure you're not setting it to inactive?

quaint zephyr Jan 4, 2021, 8:40 PM

#

Yes because when the "pickup" occurs, I look at the inspector slot's children and see that the checkmark indicates that they indeed are in active state. They are still greyed out because the parent (PlayerMenu) is inactive until the player decides to view what he got. It is when he triggers "OpenMenu" (which all it does is set the menu to active) and that's it. It's as if it remembers they were inactive and reverts them back.

#

Figured it out. Don't fret. Thanks for taking a stab a it.

Hey, I am trying to figure out how to use Event.current in OnGUI, any idea what should be put in Repaint, Layout, etc...? When I put everything that draws in Repaint, I get an error on EditorGUILayout.HorizontalScope, which says Getting control 0's position in a group with only 0 controls when doing repaint Aborting

#

I didn't find any reference to them online, no documentation about it, nothing...

#

And another question regarding GUI, When i used GetLastRect, it works fine, I use it with GUI.DrawTexture and GUI.Label and when I finish, and try to use EditorGUILayout, or GUILayout, the layout is ontop of what I drew in GUI, you can see it in the attached photo

When I try to do VerticalScope, in the Repaint, it wont let me, so I probably will need to do it in the Layout, but HOW? If Repaint is responsible (presumably...) for the drawing stuff, how can I nest stuff in scopes if I can't use VerticalScope in the Repaint?

no

#

And how do you know about the events? I didn't find a single doc about it, care to share?

simple cove Jan 5, 2021, 3:52 PM

#

ok so the main idea is:

var rect = GUILayout.BeginVertical();
// use rect here:
GUI.DrawBox(rect);
// add stuff to the layout group:
{
  // ... 
}

#

trial and error 😄

split kraken Jan 5, 2021, 3:52 PM

#

Okay so now you just wont use Layout

#

you just use GUI

#

that's an extra work

#

instead of using for example, EditorGUILayout.Slider, I will need to provide it with a rect and render the slider and logic myself

#

that is, if GUI don't have slider already (The slider was just an example)

#

I want to use all of them, at the same time

simple cove Jan 5, 2021, 3:54 PM

all EditorGUILayout even does is call the method EditorGUILayout.GetControlRect() anyway

You can't use GetControlRect if you don't have a a control

in editor land docs in not always there, and sometimes even the docs makes no effort to explain something. You'd be better off to github and dig the UnityCsReference for examples of how things are used cause there are all sorts of quirks and rarely does a "good" solution exist.

There's plenty of good solutions and practices, they're just not documented anywhere and people don't generally write about them often

@waxen sandal FYI: I was only half right yesterday.. the DeleteArrayElementAtIndex function only setting the array element to null, rather than removing from the list was only PART of the problem. The unity-only-code exception I get when using my custom property drawer seems to now only appear when I use EditorUtility.DisplayDialog("Confirm Delete", "Confirm you would like to delete this entry.", "Delete", "Cancel"); (when I replace the above with true the stack exception thrown by unity only code disappears- which is what I did yesterday during my attempts to fix stuff- then promptly forgot) What is the correct way to use a confirmation dialog like that, from inside a custom property drawer? Do I need to create an editor window or something, to prevent it from blocking property drawer code execution until it returns?

waxen sandal Jan 5, 2021, 5:04 PM

#

Think I've done that before

#

Not sure why it doesn't work

#

Might be because you're in a certain GUI event?

#

E.g. repaint or layout which causes the issue

keen pumice Jan 5, 2021, 5:08 PM

#

it certainly seems like it prevents the rest of the property drawer code from running until it returns... I've tried to invoke it only during layout and NOT during layout, alas both give the same result. done that before: you mean create an editor window to open in "parallel" then callback a function of my property drawer, on confirm?

#

oh, haven't tried NOT layout AND NOT paint.. I'll give that a go...

onyx harness Jan 5, 2021, 5:09 PM

#

You are suppose to interact with the data during input events, not during layout/repaint events.

#

Or you will probably face Object grouping exception stuff

keen pumice Jan 5, 2021, 5:14 PM

darn, that didn't seem to fix it.. I still get a stack exception even when I click "cancel" in the dialog (which does NOT change any data). Have you guys had success using EditorUtility.DisplayDialog in property drawers?

@oak umbra It sounds like you will want to create an EditorWindow derived class. Start here docs wise: https://docs.unity3d.com/ScriptReference/EditorWindow.html

For the UIToolkit ListView, how do you get KeyDownEvent for items? I can't figure it out.

severe python Jan 5, 2021, 10:55 PM

#

IIRC, you create the items the ListView contains by implementing its AddItem action right?

#

Which would mean in that same code you're going to setup a key down event like you would in any other place

#

https://docs.unity3d.com/ScriptReference/UIElements.ListView.html

#

yeah, so in the Func<VisualElement> MakeItem, you'd do what you'd normally do, something like...

public void OnEnable()
{
  var items = new List<string>(1000);
  for (int i = 1; i <= 1000; i++) item.Add(i.ToString());

  void MyCallback(KeyDownEvent evt) { /* ... */ }
  Func<VisualElement> makeItem = () =>
  { 
    var label = new Label(); 
    label.RegisterCallback<KeyDownEvent>(MyCallback);
    return label;
  };
  Action<VisualElement, int> bindItem = (e, i) => (e as Label).text = items[i];
  var listView = new ListView(items, 16, makeItem, bindItem);

  listView.selectionType = SelectionType.Multiple;
  listView.onItemChosen += obj => Debug.Log(obj);
  listView.onSelectionChanged += objects => Debug.Log(objects);
  listView.style.flexGrow = 1.0f;

  rootVisualElement.Add(listView);
}

#

the caveat here is that there are times when I need to make certain registrations when the element is attached to a panel, so I'll bounce off that, but there may be things I'm not remembering which are not relevant in the general case

#

its been a while

#

its possible that a more appropriate place to register the handler is in the bindItem Action

I did, and it did not, my best guess is that because the list view uses the arrow keys, it then tells it to stop propagating maybe? What version are you on?

severe python Jan 5, 2021, 11:10 PM

#

well, the last time I used listview was probably on like, 2018.2 or something, when it was all very experimental...

#

I hated it so much I built VisualTemplates lol

#

so like

#

https://github.com/PassivePicasso/VisualTemplates/blob/master/Editor/ItemsControl.cs

#

this is my version

#

you know, suddenly I realize its ridiculous that I built in a remove element

gloomy chasm Jan 5, 2021, 11:13 PM

#

Hot dang, the 2020.1 ListView is so much nice. Or at least is much more customizable and user friendly.. 😦

severe python Jan 5, 2021, 11:14 PM

#

VisualTemplates is kinda like WPF DataTemplates for Unity, because of that very issue

#

I wanted to be able to have a list view, that automatically rendered the right view for a piece of data it was handed, so that I could just add list views and hand them data, and define templates for that data

#

though, thats really what ContentPresenter does, ItemsControl just makes ContentPresenters and puts them inside itself, and does binding stuff

#

I didn't like that you had to write a Bind method either, it should bind like all the rest of the stuff

#

put in a binding-path to an array

gloomy chasm Jan 5, 2021, 11:18 PM

#

You know what is really cool about pre 2020.1 ListViews? If you bind a list/array property to them, they add an extra element which is the number of items! Isn't that cool and exactly what you want!

severe python Jan 5, 2021, 11:18 PM

#

Wait can you use binding-path now?

gloomy chasm Jan 5, 2021, 11:18 PM

#

Yep!

severe python Jan 5, 2021, 11:19 PM

#

oh thats awesome, I've been stuck on old versions of unity for too long

#

wait so why do you have to bind then?

#

or

gloomy chasm Jan 5, 2021, 11:19 PM

#

Well, I use the extension method BindProperty(SerializedProperty arrayProperty) that they give you.

#

You bind them to give specific data to them. Like to name each item, or to give them special fields and stuff.

#

I think it uses the PropertyDrawer for the items by default now, but don't quote me on that!

severe python Jan 5, 2021, 11:22 PM

#

oh that would be awesome because that basically gives you data templating

#

So, I guess I don't know why that doesn't work, however you could make a subclass of VisualElement and implement the ExecuteDefaultActionAtTarget method in order to ensure you see the events, and then you could figure out stuff from there
https://docs.unity3d.com/Manual/UIE-Events-Handling.html

#

either by debugging the process or just handling it

#

if you go to the bottom of the linked documentation you can see how the event propogation works

#

obviously you would wrap your item content in the custom visual element

gloomy chasm Jan 5, 2021, 11:28 PM

#

severe python oh that would be awesome because that basically gives you data templating

Hmm... nope, that doesn't work either. It gets things like MouseDownEvent, and MouseOutEvent and such, but no Key events....

severe python Jan 5, 2021, 11:29 PM

#

that makes me think this is a focus issue

#

https://docs.unity3d.com/2020.2/Documentation/Manual/UIE-Events-Dispatching.html
"The target of an event depends on the event type. For mouse events, the target is usually the topmost pickable element, directly under the mouse. For keyboard events, the target is the currently focused element."

#

FocusController.focusedElement

gloomy chasm Jan 5, 2021, 11:37 PM

#

@severe python Ah ha! It seems the ListView it self gets all of the keyboard focus, which I guess makes sense because it needs to navigate up and down? Idk, but it works if I register to the ListView it self. I was sure I had already tried that though.

severe python Jan 5, 2021, 11:38 PM

#

It's not off. It is because of the label width, and some fields have a min size. You can use EditorGUIUtility.labelWidth to set the width of the label, and you can use GUILayout.ExpandWidth, GUILayout.Width, and other methods within a Layout method to control the width.

                GUILayout.MaxHeight(200f),
                GUILayout.Width(windowWidth));

            GUILayout.BeginArea(timelineArea);
            GUILayout.Button("Test");
            //GUI.Button(new Rect(10, 10, 50, 20), "Test");
            GUILayout.EndArea();

#

This is the entire code.

#

Above it, is just some buttons and sliders

#

And I already said what's happening, nothing gets rendered inside the group or area

waxen sandal Jan 7, 2021, 4:08 PM

#

Does it get rendered at all?

solid thicket Jan 7, 2021, 4:09 PM

#

No

#

I mean, I don't know

#

maybe offscreen

#

Its not visible

#

the odd thing is that the rect is fine

#

maybe its something to do with EventType.Layout or something?

waxen sandal Jan 7, 2021, 4:14 PM

#

Looks like it's a weird interaction with GetRect

solid thicket Jan 7, 2021, 4:15 PM

#

I use it before and its working fine that's the thing

#

Its the first time I use it to create an area

waxen sandal Jan 7, 2021, 4:19 PM

#

Not quite sure what the issue is at the moment, I'd have to dig deeper which I don't have time for at the moment

#

@onyx harness might know

onyx harness Jan 7, 2021, 4:27 PM

#

solid thicket ``` Rect timelineArea = GUILayoutUtility.GetRect( GUIContent.non...

What happens if you remove all the code and use the example here? (https://docs.unity3d.com/ScriptReference/GUILayout.BeginArea.html)

solid thicket Jan 7, 2021, 4:27 PM

#

Its working fine

#

I tried it

#

That's what makes me thing its something to do with the EventType

onyx harness Jan 7, 2021, 4:27 PM

#

What I like to do when debugging is to call EditorGUI.DrawRect(rect, Color.blue)

#

It's Editor stuff right? Not in-game?

solid thicket Jan 7, 2021, 4:28 PM

#

📎 unknown.png

#

Yep

#

The rect is fine as I stated before

#

Layout -- (x:0.00, y:0.00, width:1.00, height:1.00)
repaint -- (x:0.00, y:301.00, width:1188.00, height:200.00)

onyx harness Jan 7, 2021, 4:29 PM

#

Maybe it is GUILayoutUtility

solid thicket Jan 7, 2021, 4:29 PM

#

That's what I get when I view the rect

#

When I try to separate the rect update, for say, EventType.Repaint (Because that's where the rect is valid), I get errors about doing that

#

When I try to switch to EventType.Layout I get the same thing

#

I mean doing this:

if(Event.current.type == EventType.Repaint)
  UpdateRect();

onyx harness Jan 7, 2021, 4:39 PM

#

solid thicket ``` Rect timelineArea = GUILayoutUtility.GetRect( GUIContent.non...

Who sets windowWidth?

solid thicket Jan 7, 2021, 4:39 PM

#

Me, its just position.width

onyx harness Jan 7, 2021, 4:41 PM

#

If you say the example works fine alone, but your code is impacting the current result, something in your current code is annoying the layout

#

Try to narrow it down

#

Remove some part one by one, until BeginArea starts drawing again

#

Or add them one by one

#

up to you

waxen sandal Jan 7, 2021, 4:43 PM

#

Removing the getlastrect and replacing it with a constant value works fine

#

So it's some interaction with that

onyx harness Jan 7, 2021, 4:44 PM

#

GetLastRect?

waxen sandal Jan 7, 2021, 4:45 PM

#

Getrect I meam

#

Mean

solid thicket Jan 7, 2021, 4:48 PM

#

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine;


public class TestWindow : EditorWindow
{
    [MenuItem("Tools/Test Window")]
    public static void Init()
    {
        TestWindow window = GetWindow<TestWindow>();
        window.Show();
    }

    private void OnGUI()
    {
        Rect rect = GUILayoutUtility.GetRect(
                GUIContent.none,
                "button",
                GUILayout.Height(200f));

        // Maybe its something to do with the EventType?
        Debug.Log($"{Event.current.type} -- {rect}");

        GUILayout.BeginArea(rect);
        // Draw to the entire area
        GUI.DrawTexture(rect, EditorGUIUtility.whiteTexture);
        GUILayout.EndArea();
    }
}

#

Here is a simple example

#

This example wont draw anything, but it should

#

It should draw a white rectangle (100% width of the window) with height 200

#

NOW, comment the BeginArea and EndArea out, the rectangle appears!

onyx harness Jan 7, 2021, 4:50 PM

#

nope

#

It depends what returns GetRect

solid thicket Jan 7, 2021, 4:51 PM

#

That's why there is GUILayout.Height(200f) and "button"

#

button makes it go full width in that case, and height speaks for itself

#

and you can try it yourself and see that's the case

onyx harness Jan 7, 2021, 4:52 PM

#

It's not about the content and styling

#

It's about who get drawn first between BeginArea & DrawTexture

#

BeginArea opens a clip if i'm not mistaken

#

If you move GUI.DrawTexture above BeginArea, what do you see?

solid thicket Jan 7, 2021, 4:53 PM

#

yes

#

Only stuff inside the area gets hidden

#

Im not following you about the draw order

#

What do you mean?

onyx harness Jan 7, 2021, 4:55 PM

#

if BeginArea draws a non-opaque background, it might probably hide the white texture

solid thicket Jan 7, 2021, 4:55 PM

#

Why would BeginArea draw something

onyx harness Jan 7, 2021, 4:55 PM

#

Hehehe wonders of Unity Editor

solid thicket Jan 7, 2021, 4:56 PM

#

Well it calls GUI.BeginGroup, and I don't think it draws something

#

how did you come to that conclusion?

onyx harness Jan 7, 2021, 4:56 PM

#

Almost any GUI has a Style applying, and it draws stuff

#

Because there are a lot of surprises in GUI

solid thicket Jan 7, 2021, 4:56 PM

#

So I need to try another style?

onyx harness Jan 7, 2021, 4:57 PM

#

In your code just above, if you draw GUILayout.Button("Test"), it works, right?

#

(Between the Area)

solid thicket Jan 7, 2021, 4:58 PM

#

no

#

BUT

#

You were onto something with the GUIStyle

onyx harness Jan 7, 2021, 4:58 PM

#

Then, now if you replace GetRect with a manually assign Rect, it works

#

Like Navi stated

solid thicket Jan 7, 2021, 4:59 PM

#

I replaced "button" with new GUIStyle and I see a small pixel below the tab

solid thicket Jan 7, 2021, 4:59 PM

#

onyx harness Then, now if you replace GetRect with a manually assign Rect, it works

You mean hard-coded values?

onyx harness Jan 7, 2021, 4:59 PM

#

yep

solid thicket Jan 7, 2021, 5:00 PM

#

Well, that's kind of a hacky way

#

I need to find a proper Rect

#

like GetLastRect

onyx harness Jan 7, 2021, 5:01 PM

#

Yeah yeah we know, it was just for the test

solid thicket Jan 7, 2021, 5:01 PM

#

well hard-coded does work

onyx harness Jan 7, 2021, 5:01 PM

#

We need to find the culprit first

#

What if you remove completely the style?

solid thicket Jan 7, 2021, 5:01 PM

#

Well I assume you mean with the GetRect?

onyx harness Jan 7, 2021, 5:02 PM

#

yes (sorry)

solid thicket Jan 7, 2021, 5:02 PM

#

you mean like new GUIStlye()?

#

a default style?

#

Oh, you mean use it with a hardcoded rect?

onyx harness Jan 7, 2021, 5:03 PM

#

Let me find an overload that does not use a style

solid thicket Jan 7, 2021, 5:03 PM

#

There are a few

#

I just need to specify stuff like width and height

onyx harness Jan 7, 2021, 5:04 PM

#

Use the first one

#

GetRect(position.width, 200F)

#

Does it give something interesting?

solid thicket Jan 7, 2021, 5:05 PM

#

Surprisingly, no :\

onyx harness Jan 7, 2021, 5:05 PM

#

Is the rect somehow correct?

solid thicket Jan 7, 2021, 5:05 PM

#

            
            Rect rect = GUILayoutUtility.GetRect(position.width, 200f);

            GUILayout.BeginArea(rect);
            GUILayout.Button("Test");
            GUILayout.EndArea();

onyx harness Jan 7, 2021, 5:05 PM

#

(I'm not even surprised myself)

solid thicket Jan 7, 2021, 5:05 PM

#

Well I am, I thought maybe that way its like using hard-coded values

onyx harness Jan 7, 2021, 5:06 PM

#

what about GetRect(position.width, position.width, 200F, 200F)

#

It's not hardcoded, since height = 200F is also used like this in your first code

solid thicket Jan 7, 2021, 5:06 PM

#

onyx harness what about GetRect(position.width, position.width, 200F, 200F)

nothing

#

I know its not hard coded

#

I meant maybe it will behave the same way

onyx harness Jan 7, 2021, 5:07 PM

#

Try GetRect(0F, 0F, GUILayout.Width(position.width), GUILayout.Height(200F))

solid thicket Jan 7, 2021, 5:07 PM

#

Same result

onyx harness Jan 7, 2021, 5:08 PM

#

Well shit, GetRect is definitely colliding with BeginArea

solid thicket Jan 7, 2021, 5:08 PM

#

Lol

#

That's odd because I thought people use it a lot

onyx harness Jan 7, 2021, 5:08 PM

#

But I feel it is somewhat expected

solid thicket Jan 7, 2021, 5:08 PM

#

it would have come up but I didn't find anything about it

#

Yeah, I think so too

onyx harness Jan 7, 2021, 5:08 PM

#

GetRect will reserve a space

#

BeginArea is suppose to start a new layout in a given rect

solid thicket Jan 7, 2021, 5:09 PM

#

And it does

📎 unknown.png

#

Thats a second button under the EndArea

onyx harness Jan 7, 2021, 5:10 PM

#

which is fine

solid thicket Jan 7, 2021, 5:10 PM

#

Yep

#

That's where it should be

#

Unlike someone else...

onyx harness Jan 7, 2021, 5:11 PM

#

What you can use to trick the layout

#

Use GUI.Space

#

GetLastRect

#

Set the correct width and move on

solid thicket Jan 7, 2021, 5:12 PM

#

Yeah that's my fallback

#

I'll dig some more inside Shader Forge and see how she uses it

#

I saw she uses only GUI.BeginGroup

#

But I don't know

onyx harness Jan 7, 2021, 5:12 PM

#

Which is for purely clipping

#

GUI is much more cumbersome but much more reliable than its counterpart GUILayout

#

I use GUILayout for quick prototyping, GUI for production

solid thicket Jan 7, 2021, 5:14 PM

#

Yeah I started using GUI, getting the hang of it on the way

#

I want to create a timeline now using it

onyx harness Jan 7, 2021, 5:15 PM

#

You'll have much less headache using GUI directly

#

Things like timeline needs precision

#

Good luck

Thanks 🙂

#

Thanks for the help also! really appreciated

{
public override void OnInspectorGUI()
{
serializedObject.Update();
EditorList.Show (serializedObject.FindProperty("playerBodyParts"));
serializedObject.ApplyModifiedProperties();
}
public static void Show (SerializedProperty list) {
EditorGUILayout.PropertyField(list);

    for (int i = 0; i < list.arraySize; i++)
         EditorGUILayout.PropertyField (list.GetArrayElementAtIndex(i));
}

}

im just trying to follow this tutorial and i dont see what im doing wrong https://catlikecoding.com/unity/tutorials/editor/custom-list/

how do you "trim" a sprite sheet via code through its SpriteMetaData https://docs.unity3d.com/ScriptReference/SpriteMetaData.html the docs don't say and I am missing this functionality for my spritesheet script

#

im looking for the functionality from the Trim button in the built-in sprite editor through code

since it, for no reason at all, doesn't support multi-select trim for sprite slices in the sheet.

waxen sandal Jan 8, 2021, 9:49 AM

Is your editor for GEnerable?

If so you can just enable the bool editorForChildClasses on the attribute

i'm trying to use PrefabUtility.GetPropertyModifications to see what my code prior just changed, and somehow the properties don't include all my own variables

is that by design?

my main problem is that PrefabUtility.ApplyObjectOverride does not work for me.

only PrefabUtility.ApplyPrefabInstance applies everything needed, but also too much, like the transform

hy all, very specific question incomming :
in unity, you can create your own packages. you can 'embed' them so that they show as 'in development' in the package manager (not many people know that, thought i'd share 🙂 )
in case there's someone here that has done this : do you know of a way to identify which packages are embeded (or how to differentiate them from regular packages) I'm trying to achieve to know wether a specific instance of a scriptable object is 'read only' because it's from a protected package, or not (only editor, not runtime)

#

nvm, found it. posting the answer in case someone ever needs to know: PackageInfo.cs contains a method FindForAssetPath (to find package of an asset), and that info also contains 'package source' which would be embedded (or not)

waxen sandal Jan 8, 2021, 1:15 PM

Path.GetFullPath also works

#

Don't ask me how

thin fossil Jan 8, 2021, 1:53 PM

@waxen sandal cannot find anything on creating scenes in the source. No clue how unity does it

They rarely use CreateAssetMenu, never use CreateAsset with scenes and never use SceneAsset in any instantiation context 🤔

    collapseFootIK =
        EditorGUILayout.Foldout(collapseFootIK, "Feet IK");
    if(collapseFootIK)
    {
        EditorGUI.indentLevel += 1;
        EditorGUILayout.PropertyField(serializedObject.FindProperty("rightFootTarget"));
        EditorGUILayout.PropertyField(serializedObject.FindProperty("rightFootPole"));

    serializedObject.ApplyModifiedProperties();

For Unity, in the editor I can set the public Transform teleportTo, where I can teleport my player to a specific teleportTo.position.

Is there a better way of doing this? I.e. I want to choose a location in my scene, but it seems I have to create a gameObject for every coordinate. I could do Vector3, but I won't be able to "preview" the location as easily or move it in Scene View

I would think so. I mean you can just look at the Unity C# source reference to see how it is used. That's what I do all the time!

patent pebble Jan 8, 2021, 10:01 PM

#

yeah I'll dig around their github source code to see how it's used

#

just wanted to see if there was some neatly explained info online

#

I guess they didn't bother expanding the docs for this since it's still very new or experimental

gloomy chasm Jan 8, 2021, 10:02 PM

#

Guess so, some things are just like that with little to no docs.

patent pebble Jan 8, 2021, 10:03 PM

#

yeah they don't seem to bother much with some Editor extension APIs, sadly

Hello

#

I'm trying to write a propertydrawer which handles drawing references to scriptable object assets. I want to display fields from the referenced object inline, and have them update in the inspector as changes happen.

#

So far, the changes in the scriptable object don't cause an update in the inspector the drawer is being rendered in.

#

Which makes sense since the object which is changing is a separate object form the behaviour the inspector is rendering.

#

Just having a hard time figuring out how to accomplish this.

gloomy chasm Jan 9, 2021, 5:03 AM

#

@urban hazel Are you using SerializedProperties?

urban hazel Jan 9, 2021, 5:03 AM

#

Yep

#

Thus far to display the fields of the scriptable object I have reference to, I've had to create a scriptable object instance for that object.

#

It works to display the values of the object pointed to, but as they change, they don't update in the inspector.

gloomy chasm Jan 9, 2021, 5:19 AM

#

@urban hazel No, to get the fields, you create a SerializedObject from the ScriptableObject

urban hazel Jan 9, 2021, 5:20 AM

#

Well, the field in particular which is the type of the ScriptableObject, I do the following:

var variableSO = new SerializedObject(variableField.objectReferenceValue);
variableSO.Update();
SerializedProperty varValueProp = variableSO.FindProperty("Value");
erializedProperty varRuntimeProp = variableSO.FindProperty("RuntimeValue");```

#

Not sure if that's what you're refering to.

#

so variableField is the serializedProperty which holds a reference to a ScriptableObject asset type I have in my project.

#

I wanted to display data from within that object in this inspector

#

Is this what you were asking?

gloomy chasm Jan 9, 2021, 5:21 AM

#

Yeah, that's it.

#

So, what part isn't updating?

urban hazel Jan 9, 2021, 5:22 AM

#

When I display varValueProp and vaRuntimeProp, if I change their values from code the updates don't hit the inspector

#

Not unless I hover the inspector while doing it.

#

The inspected object doesn't get told to update since this SO reference it points to is receiving the changes,.

#

And I mean, that makes sense

#

I just want to work around it.

#

Cleanly if possible.

editors don't repaint unless events are sent to them or they're part of editors that override RequiresConstantRepaint

i am struggeling on why the obj is null when i enter run mode:

           t.go = (GameObject)EditorGUILayout.ObjectField(new GUIContent("Go", "Event GameObject"), t.go, typeof(GameObject), true);
             if (t.go != null)
              {
                   Debug.Log("assign obj here");
                   t.obj = t.go.GetComponent<CustomEvents>();
                   Debug.Log(t.obj.ToString());
               }

---------------------------------
    public GameObject go;
    public object obj;

#

while the gameobject "go" is ok

#

talking of the obj field

You should use SerializeProperty instead of getting and setting the fields directly like that. I assume the problem is that the change is not being saved.

whole steppe Jan 9, 2021, 3:36 PM

#

on the go field?

gloomy chasm Jan 9, 2021, 3:37 PM

#

whole steppe on the go field?

Yeah, and just any value you want to set while in the editor.

whole steppe Jan 9, 2021, 3:39 PM

#

not quiet sure how to do this

gloomy chasm Jan 9, 2021, 3:43 PM

#

@whole steppe Like so. This is assuming that go is just a public field. If it is a property, then you want the backing field with the [SerializeField] attribute.

SerializedProperty goProperty = serializedObject.FindChildProperty("go");

EditorGUILayout.PropertyField(goProperty, new GUIContent("Go", "Event GameObject"));
if (goProperty.objectReferenceValue != null)
{
  serializedObject.FindChildProperty("obj").objectReferenceValue = t.go.GetComponent<CustomEvents>();
}
// This is important, this actually applies the changes, without this the new values will not be saved.
serializedObject.ApplyModifiedProperties();

okay let me see

#

hmm not able to Drag Drog the GameObject from the Scene now 🙂

#

it is a Scriptable Object and i using some System.Reflection

gloomy chasm Jan 9, 2021, 3:57 PM

whole steppe hmm not able to Drag Drog the GameObject from the Scene now 🙂

Correct, you can't and shouldn't reference scene objects from assets.

Greetings; I am currently making a Property Attribute for a project of mine where said Property Attribute exposes the information contained in a Scriptable Object directly to a component that contains said Scriptable Object.

#

So far, i found out that using Editor.Create(target) works fine with the exception of the fact that i am using editor.OnInspectorGUI() which draws everything at the bottom of the inspector.

#

Is there any way of having the same functionality as the OnInspectorGUI() but also control where said element is being drawn?

#

@fickle copper you probably have to either create Custom Editors for editor you are creating with CreateEditor or draw everything manually

#

It's been a while since I did stuff with nested editors but I remember it being relatively simple

patent pebble <@!137592928133447682> you probably have to either create Custom Editors for edi...

Here is the thing, i dont know how to draw everything manually

#

especially since i dont know what properties the object contains

#

I straight up lack that information as its a Property Attribute that works on any scriptable object.

#

I tried GetIterator() but im getting some weird behaivour and/or errors out of it.

#

I can send you a screenshot of how the current editor looks with CreateEditor if you want

patent pebble Jan 9, 2021, 5:14 PM

#

@fickle copper I mean if you want to draw it in the inspector view you can just use a custom editor for the type that you want to draw

#

I expect that you are just getting the nested editor at the bottom of your inspector, but yeah send the screenshot anyways

fickle copper Jan 9, 2021, 5:14 PM

patent pebble Jan 9, 2021, 5:15 PM

#

how do you want it to look?

fickle copper Jan 9, 2021, 5:15 PM

#

I want the nexted editor to draw right below its data holder

#

So the Test Scriptable Object should have its editor right below it.

#

And the same for the Instance Event one

#

This way, i can use this Attribute on lists

#

As it is rn, if i were to use it on a list, it would draw every editor at the bottom

#

And that gets confusing if you have multiple scriptable objects of the same type.
