I want to find fields of specified type and change their values. For finding its fields, I use this piece of code:
propertyType.GetFields(BindingFlags.Public | BindingFlags.Instance);
And for Setting and getting their values I should use these functions:
FieldInfo.GetValue and FieldInfo.SetValue. As you know they need instance as an input. So I should first create a instance of that type and assign it to these functions.
The problem is as I know and understand the instance should be created once because of not losing values if I'm right but I can't serialized that instance because its type is System.Object and Unity can't serialize it.

Do I do it wrong ? I miss anything between ?

Heyo, maybe one of the smart folks here can help me with this ^^ I wanted to initialize some editor stuff on object creation. Is there a way to access newly created, instantiated or duplicated objects in the editor? An event would be best, but I'm willing to hack around unity to get what I want 😅

gloomy chasm Sep 4, 2019, 4:22 PM

#

@smoky radish I'm sorry I don't understand what you are trying to do or what the problem is.

#

@wind jungle as far as I know there is no event or callback or anything to hook in to that is called when an object is created. The best you can do is either call an delegate/event on your own in the method that you use to create a gameObject, or you can put something in the Awake method and have the script be Execute In Edit Mode

smoky radish Sep 4, 2019, 4:39 PM

#

I use this repository for what I want to build.
https://bitbucket.org/rotorz/classtypereference-for-unity/src/master/
As you see it is a dropdown propertyAttribute which items are System.Type.
Now I want to add another functionality to it. After selecting item in dropdown I want to show its fields. So what I do now is I use _classRef of that PropertAttribute which is AssemblyQualifiedClassName and find the System.Type of selected item. Then I find FieldInfo of that type. For changing those fields value I need to use FieldInfo.GetValue and FieldInfo.Setvalue. As you know these 2 functions need instance of the selected type. So I can create the instance by Activator.CreateInstance() so the return type is System.Object.
For storing edited values of those type fields I should have same instance everytime as I understand. So I should first create that instance, then store it and then use it every time.
The problem is for storing I should store created instance in System.Object variable but System.Object is not serialized. So I want to know what I should do then ?

#

@gloomy chasm

#

Now I'm thinkong to store that instance in string instead of object but I don't know if it is possible or not. Then use that string to retrieve created instance.

#

@gloomy chasm now do you get what I want to do ?

gloomy chasm Sep 4, 2019, 4:58 PM

#

What you want to do is to create and instance of the type that is selected. What I would do is have a field in the script with the attribute that you set to be the instance. It is a little are to tell you how to proceed because I don't know what your use case is. Like will all of the types derive from a single class type?

#

@smoky radish ^

smoky radish Sep 4, 2019, 5:01 PM

#

Hmmm, I didn't get what you mean. I can create an instance of these selected type but I don't know how to store it.

#

@gloomy chasm

gloomy chasm Sep 4, 2019, 5:04 PM

#

I mean that in order for a class to be serialized by unity it needs to have the attribute [serializable]. And also what is the point of editing the values of a class that isn't stored? So why don't you store it on your Mono or scriptable object that the dropdown is on?

#

@smoky radish

smoky radish Sep 4, 2019, 5:07 PM

#

Yup but System.Object is not never serialized.

#

If I store them in ScritableObject which I'm writting editor for it after playing it won't be reset ?

#

@gloomy chasm

gloomy chasm Sep 4, 2019, 5:12 PM

#

Exactly @smoky radish so, you need to have all the objects inherit from an class that is serializable. Also, you can use I think it is called ISerializeCallback or something like that to make it so a scriptable object doesn't save it's data in playmode

smoky radish Sep 4, 2019, 5:15 PM

#

So what change if those classes inherits from a serializable class ?

#

@gloomy chasm

gloomy chasm Sep 4, 2019, 5:18 PM

#

I am having a hard time understanding what your use is so I am not sure how to help you tbh

smoky radish Sep 4, 2019, 5:22 PM

#

Hmmm, I explained it above.
Assume there are 4 types in dropdown, I should create instance of them and store them because I should use same instance each time for getting and setting fieldInfo values (I think values which are edited will be reset if I use new created instance in getting and setting). But because instances type is System.Object they can't be serialized.

Anyone know how to use a PanelChangedEvent in UIElements? there seems to be zero documentation on it

#

there's just a PanelChangedEventBase

#

is there no event for when a panel changes size???

#

this is like the dark ages

#

any way to hack in an event for when a panel's size is changed?

#

how can unity overlook something so basic?

#

it must be here somewhere

gloomy chasm Sep 4, 2019, 6:02 PM

#

Why do you need to know when the panel changes size?

frail phoenix Sep 4, 2019, 6:02 PM

#

so I can draw the background grid

#

and also.. the size is NaN on initialization

#

if someone resizes the window then I need to draw more or less background

#

ok, I found the properties that are populated.. they're just berried in an undocumented distant child object .panel.visualTree.localBound

#

if you look at the object's localBound then it's just a bunch of NaNs

smoky radish Sep 4, 2019, 6:41 PM

#

So you don't have any ideas ? @gloomy chasm

cedar reef Sep 4, 2019, 8:14 PM

#

@smoky radish If the actual type of the reference is serializable, store it as that type rather than just object

outer cove Sep 4, 2019, 9:16 PM

📎 unknown.png

#

how would one go about making something like this

#

or more specifically, are those squares on the right an existing unity object or not?

gloomy chasm Sep 4, 2019, 9:56 PM

#

@outer cove no you would need to make them. I would guess they are doing something like EditorGUI.DrawRect() to draw them.

outer cove Sep 4, 2019, 9:57 PM

#

ok

jagged fog Sep 4, 2019, 10:21 PM

#

guys how can I make a delay like: run this every second

#

Instantiate(myPrefab, new Vector3(Random.Range(-10,20), 24, -5), Quaternion.identity);

wispy delta Sep 4, 2019, 10:24 PM

#

Are you wanting to do this in the editor or in playmode @jagged fog ?

jagged fog Sep 4, 2019, 10:24 PM

#

well during playmode

#

it spawns rockets and its way too fast

#

so i want it to spawn a rocket every second or 0.1 s

#

invoke only delays it once and the other one WaitForSeconds didnt work in the update function

wispy delta Sep 4, 2019, 10:27 PM

#

this channel is for editor scripting (extensions, custom windows/inspectors etc) so in the future I'd ask in #💻┃code-beginner but there's two ways to go about it.

Store the last shoot time and don't shoot again until some time has passed

float lastShootTime = 0f;

void Update()
{
    // Shoots once every second
    if (Time.time - lastShootTime > 1f)
    {
        Shoot();
        lastShootTime = Time.time;
    }
}

The other option would be to use a coroutine. You don't want to put it in Update because it is called every frame. You should start the coroutine in Start or OnEnable

void Start()
{
    StartCoroutine(ShootRoutine());
}

IEnumerator ShootRoutine()
{
    while (true)
    {
        yield return new WaitForSeconds(1f);
        Shoot();
    }
}

thanks

visual stag Sep 4, 2019, 10:42 PM

@frail phoenix registering a GeometryChangedEvent probably does it too. I mean, there's likely a whole heap of event types I haven't learnt yet 😊

thanks, I'll look into it

Curious if anyone here has written editor code to check files out from perforce? Wondering if there is some sort of API I can hook into or if I just do it all virual commandline.

#

I.E. you modify a scriptable object in an editor window but perforce has it read only (it's not checked out) and now I want to check it out to apply the modifications to it.,

grizzled minnow Sep 5, 2019, 7:51 AM

#

@hoary surge Yes, there is an API for that!

            {
                if (UnityEditor.VersionControl.Provider.onlineState == UnityEditor.VersionControl.OnlineState.Online)
                {
                    UnityEngine.Object projectAsset = (AssetDatabase.LoadAllAssetsAtPath("ProjectSettings/ProjectSettings.asset")[0]);
                    UnityEditor.VersionControl.Provider.Checkout(projectAsset, UnityEditor.VersionControl.CheckoutMode.Both);
                }
            }```

@grizzled minnow thank you for that! Legit awesome info.

#

is it possible to assign Editor script to more than one script:

[CustomEditor(typeof(AudioClipRandomSet), true)]
public class AudioClipRandomSetEditor : Editor

#

That AudioClipRandomSetEditor script is correct both for AudioClipRandomSet and AudioClipWeightedSet

#

Is it possible to assign that Editor also for AudioClipWeightedSet?

stark geyser Sep 5, 2019, 8:42 AM

#

I think you may have to use base class for that

robust sentinel Sep 5, 2019, 8:42 AM

#

I can't do that

#

Because it's generics, Unity doesn't serialize Interfaces, and overall it's mess (fighting against Unity with its non-serializing interfaces...)

stark geyser Sep 5, 2019, 8:44 AM

#

I mean if they have intermediate AudioClipSet class for them both, just to couple them, would it break generics?

robust sentinel Sep 5, 2019, 8:44 AM

#

Yeah, I can't make it: I can show

#

Base (but anything special):

    public abstract class ScriptableObjectSet<T> : ScriptableObject
    {
        public abstract T GetItem();
    }

RandomSet<T>

    public class RandomSet<T> : ScriptableObjectSet<T>
    {
        [SerializeField]
        private T[] items;
    
        public override T GetItem()
        {
            if (items == null || items.Length == 0) throw new Exception("Set must contain any element to call GetItem method.");

            return items[Random.Range(0, items.Length)];
        }
    }

#

WeightedSet<T>

    public class WeightedSet<T, TElement> : ScriptableObjectSet<T>
        where TElement : WeightedSetElement<T>
    {
        [SerializeField]
        private TElement[] items;
    
        public override T GetItem()
        {
            if (items == null || items.Length == 0) throw new Exception("Set must contain any element to call GetItem method.");

            float totalWeight = 0.0f;
            for (int i = 0; i < items.Length; i++)
            {
                totalWeight += items[i].weight;
            }

            float choice = Random.Range(0.0f, totalWeight);
            for (int i = 0; i < items.Length; i++)
            {
                if (choice > items[i].weight)
                {
                    choice -= items[i].weight;
                }
                else
                {
                    return items[i].item;
                }
            }

            throw new InvalidOperationException("This program location is thought to be unreachable.");
        }
    }
    
    [Serializable]
    public class WeightedSetElement<T>
    {
        public T item;
        public float weight;
    }

#

That WeightedSet could be simpler in pure c#, but Unity...

#

Implementation:

[CreateAssetMenu(menuName = "Snake/Sets/AudioClipWeightedSet")]
public class AudioClipWeightedSet : WeightedSet<AudioClip, AudioClipWeightedSetElement>
{
}

[System.Serializable]
public class AudioClipWeightedSetElement : WeightedSetElement<AudioClip>
{
}

#

I have to make that "SetElement" because Unity won't serialize WeightedSetElement<AudioClip>[] items

stark geyser Sep 5, 2019, 8:50 AM

#

I've used this before, I just don't remember if it survives another layer of inheritance.

robust sentinel Sep 5, 2019, 8:51 AM

#

I really wanted to have something like base class for AudioClipRandomSet and AudioClipWeightedSet (like AudioClipSet) but I can't do that in Unity

#

it's possible with interface (really weird, but working solution), but it's not possible in unity like I said

stark geyser Sep 5, 2019, 8:53 AM

#

might have to create extra editor script for it then

#

Oh yea, looked it up, my thing wasn't using generics for this part, so it had base class common for the editor. I've used generics in other thing just to be able to reference scene objects in assets.

robust sentinel Sep 5, 2019, 9:17 AM

#

hmm I got different question

#

is it possible to make an editor for scripts which implements some interface

#

?

#

Like this:

#

[CustomEditor(typeof(IAudioClipSet), true)]

smoky radish Sep 5, 2019, 10:07 AM

#

The class which inherits from ScriptableObject is serialized itself ?

#

@cedar reef I've tested that but the problem is if I create base class for those classes which are in dropdown and after creating instance, cast them with that base class after playing mode deserialization in according to the base class and child class are not existed anymore.

#

So ScriptableObject just serialized if it is an asset in the project 😕

#

Still I don't know how to serialize type instance 😕

stark geyser Sep 5, 2019, 10:54 AM

#

@robust sentinel Here's a bit convoluted idea how to do that. If I understood it correctly. I could be missing the point entirely, generics are still complicated for me :D
Inherited scripts can't use inspector of the base which inherits from a generic. But. They all can use the inspector of the class previous to generics. So this is working, I think.

//Base class
public abstract class ScriptableObjectBase : ScriptableObject {
    abstract public Func<ScriptableObjectBase> GetItem { get; }
}
//going into generic implementation
public abstract class ScriptableObjectSet<T> : ScriptableObjectBase {
    public override Func<ScriptableObjectBase> GetItem { get => () => this; }
}
//then used with a needed generic type
[CreateAssetMenu(menuName = "Custom/GenericsInheritedSO", fileName = "GenericsInheritedSO")]
public class GenericsInheritedSO : ScriptableObjectSet<ScriptableObject> {
}
//and all of its variants would work with this inspector pointing to the base
[CustomEditor(typeof(ScriptableObjectBase), true), CanEditMultipleObjects,]
public class GenericsInspector : Editor {
    private ScriptableObjectBase scriptableObjectBase;

    private void OnEnable() {
        scriptableObjectBase = (ScriptableObjectBase)target;
    }

    public override void OnInspectorGUI() {
        base.OnInspectorGUI();
        if (GUILayout.Button("Get Item")) {
            Debug.Log(scriptableObjectBase.GetItem().name);
        }
    }
}

#

Done editing 🙂

visual stag Sep 5, 2019, 10:59 AM

#

What's the reason for the Func over just having a property of ScriptableObjectBase?

stark geyser Sep 5, 2019, 11:00 AM

#

It could be a regular method isn't it? I was overthinking it

#

I wanted a way to return universal value without specific type

#

But ended up just returning base class

visual stag Sep 5, 2019, 11:02 AM

#

Yeah, it is definitely missing the problem too

#

though I really don't think there is a better way of doing it

#

it's just an awful generics mess to get it done

#

where you have to create solidly declared classes for everything you do

stark geyser Sep 5, 2019, 11:04 AM

#

This abomination works though, at least returning the correct current class, I haven't tested if I could use it in a collection

#

I probably should stay away from generics 👀

visual stag Sep 5, 2019, 11:06 AM

#

I wonder whether...seeing as these are SOs

#

you could use an ISerializationCallbackReciever to put them into an array of a base type or something...

#

I dunno, it gets so sprawling it's hard to know exactly what you're dealing with

How about try UIElements instead? It's easy to scaleable, flexable, customizable.

#

I looked at it, but I can't figure out how to access certain styles and images from unity that I want. Like the 'options dropdown' (thing at the top right of each window)

gloomy chasm Sep 5, 2019, 3:03 PM

#

@odd swan I am taking another look at using UIElements, and was wondering sense you seem to be using it pretty well. Do you know what the best way to link a variable with a visual element is? (Like if I have a bool and want to show it as a toggle, how do I connect the two?)

odd swan Sep 5, 2019, 3:08 PM

#

there's many way to implement of this, Unity recommend use Bind feature, but I won't to use that, because I had used custom data structure about this, so I make MVC pattern between SerializedObject / Property my self.
Detect content changes use Manipulator to detect content change then call ApplyModifiedProperties().
In for editor side, detect Undo/Redo changes use register method to Undo.undoRedoPerformed to detect content change then apply to input elements.

#

sorry my poor English

#

And rewatched question, I think you might meaning Popup

#

https://docs.unity3d.com/ScriptReference/EditorGUILayout.Popup.html

#

Drag and drop can more easier to implement with UIElements, when you had knowledge about web development (HTML, CSS)

anybody here encountered Serialization depth limit problem when dealing with UnityEvent ? i encountered it in a really really weird way

Serialization depth limit 7 exceeded at 'UnityEngine.Events::ArgumentCache.m_ObjectArgument'. There may be an object composition cycle in one or more of your serialized classes.

Serialization hierarchy:
8: UnityEngine.Events::ArgumentCache.m_ObjectArgument
7: UnityEngine.Events::PersistentCall.m_Arguments
6: UnityEngine.Events::PersistentCallGroup.m_Calls
5: UnityEngine.Events::UnityEventBase.m_PersistentCalls

Serialization depth limit 7 exceeded at 'UnityEngine.Events::PersistentCall.m_Target'. There may be an object composition cycle in one or more of your serialized classes.

Serialization hierarchy:
8: UnityEngine.Events::PersistentCall.m_Target
7: UnityEngine.Events::PersistentCallGroup.m_Calls
6: UnityEngine.Events::UnityEventBase.m_PersistentCalls

#

and yes, before u ask, the hierachy only shows 8765 /876 , the root aren't listed

gloomy chasm Sep 5, 2019, 3:22 PM

#

Ah, thank you @odd swan
So like this is the recommended way then?

SerializedProperty prop = serializedObject.FindProperty("_enabled");            
Toggle enabledToggle = _rootElement.Q<Toggle>("enabled");
enabledToggle.BindProperty(prop);

odd swan Sep 5, 2019, 3:24 PM

you should checkout more about MVC pattern, Unity UIElements(uxml), .NET WPF(xaml), Vue.js(html, js library) does exactly with this design

waxen sandal Sep 5, 2019, 3:24 PM

@zealous coral Maybe the log file has more information?

this is pusdo code, find and read documantation

your example also works, but if you want more make less code, use Binding from layout

Rip :/

frail phoenix Sep 5, 2019, 3:45 PM

#

@zealous coral I encountered that when I had a class that got serialization callbacks and which had a more derived version of itself as a variable

#

basically if you use inheritance and through any path the class contains a variable of itself then you'll hit that

zealous coral Sep 5, 2019, 3:48 PM

#

@frail phoenix thanks for that, but that isn't my case right now :/

#

because when I ran into the issue I didn't think I should either

zealous coral Sep 5, 2019, 3:51 PM

#

yup i do use inheritance, and i know the most common way "Serialization depth limit" error could be hit - A class containing a variable of the same class

[System.Serializable]
public class A
{
    public A a;
}

i am not facing this cause right now

#

it's specifically caused by UnityEvent... somehow

frail phoenix Sep 5, 2019, 3:53 PM

#

@glad falcon it sounds like your canvas may be a child of the player. Change it's order in the hierarchy.

zealous coral Sep 5, 2019, 3:53 PM

#

and the worrying part is, my code is working fine, but the Warning (not error) log remains

glad falcon Sep 5, 2019, 3:54 PM

#

It's not a child of the player

frail phoenix Sep 5, 2019, 3:54 PM

#

ok, well unity events use the serialization callbacks and you have to create a class to use them

glad falcon Sep 5, 2019, 3:54 PM

#

I can put it anywhere in the hierarchy and it still happens

#

I've also tried changing the render mode to world view, then my canvas disappears

zealous coral Sep 5, 2019, 3:55 PM

#

what is its render mode ?

#

it matters

glad falcon Sep 5, 2019, 3:56 PM

#

I changed it to world view, assigned my main camera to it, then it disappears

frail phoenix Sep 5, 2019, 3:56 PM

#

@glad falcon I would suggest locking it to a camera

#

that sounds good. you just have to reposition it now that you changed the render mode

glad falcon Sep 5, 2019, 4:09 PM

#

Still having trouble, sorry for the bother. If I make a new camera, it doesn't show the scene. I copied pasted my current camera and it shows the scene, but I'm not sure where to place it. If I place the new camera directly over my dialogue box it's huge compared to how it is in screen overlay

I agree, Shady Mike, UIElements seems to have a lot of bugs

#

I'm surprised that it got out of preview

#

but you didn't say what your issue is @valid sonnet

valid sonnet Sep 5, 2019, 5:14 PM

#

Just look at the gif @frail phoenix

#

VisualElements disappear, scale down randomly etc.

#

maybe I have a style bug in CSS

frail phoenix Sep 5, 2019, 5:15 PM

#

no one except you can tell what you intend to happen when you press a button just from the gif

#

have you inspected the elements in the UIElements debugger?

tranquil saffron Sep 5, 2019, 6:12 PM

#

Can somebody please explain to me why this is working as intended:

    private void OnCollisionEnter2D(Collision2D collision)
    {
        AudioSource.PlayClipAtPoint(breakClip, transform.position);
        Destroy(gameObject);
        level.RemoveBlock();
    }

While this causes the Blocks to stay in the scene and don't destroy themselves?

    private void OnCollisionEnter2D(Collision2D collision)
    {
        AudioSource.PlayClipAtPoint(breakClip, transform.position);
        level.RemoveBlock();
        Destroy(gameObject);
    }

(RemoveBlock() just decreases an integer in Level to keep track when all blocks are destroyed.)

#

Actually now it's working.
This is confusing.

stark hull Sep 5, 2019, 7:39 PM

#

My guess is some external script is doing something or something outside of the code snippet you send @tranquil saffron

tranquil saffron Sep 5, 2019, 8:03 PM

#

Actually it was me being stupid.
I added the "Level" game object to the wrong scene, hence it wasn't present, resulting in an error on level.RemoveBlock();
I guess it returned the function on that error, ignoring the Destroy() call afterwards.

That's super cool @gloomy chasm. Nice work. To sort out the depth, maybe you could look at how vfx graph draws the bounds handles in its preview?

looks like they draw a cube wireframe mesh. so no handles used there :(

cedar reef Sep 7, 2019, 2:31 AM

#

You use either the old IMGUI system or the new UIElements to make a custom editor

#

IMGUI is doing it through code by inheriting from EditorWindow ( https://docs.unity3d.com/ScriptReference/EditorWindow.html ), and UIElements are a more HTML + CSS style of creating an editor

tribal skiff Sep 7, 2019, 3:39 AM

@cedar reef ohh, so... How do they make these elements look different, and not buttons tho...

visual stag Sep 7, 2019, 3:40 AM

Window/Analysis has a UIElement debugger by default, and finding the IMGUI one is pinned to this channel

#

You can use those to find the styling

which you can provide to the controls

the IMGUI one has a stack trace too which you can look at the source code of

@smoky radish All you need to do is add the attribute [Serializable] to the class for it to be serialized.

#

@keen oasis you may get better luck n #💻┃code-beginner. This channel is for extending the editor specifically. And to answer your question, it really just depends. Sometimes it makes sense to write something yourself, either for learning or for specific function, and other times it doesn't make sense to reinvent the wheel.

Thanks @polar glacier it seems that it only returns the objects that are fully inside of the rect. Which is how the selection function works so I guess that makes sense.
What I am trying to do is to get an object that has a specific component on it when the mouse is over it and ignore all other gameobjects. But having a hard time figuring out how to do that :/

Any idea what I'm doing wrong?

seems to be related to my engine, I'll figure it out

Ok maybe not, whenever I apply a change to the texture type, even in the editor, it gets reverted back to default

Hello all. =)
I've been trying to make a custom editor and property drawer that lets you pick one out of several concrete types deriving from the same base type, and then lets you edit parameters for your chosen type.
Every idea I had was very hackish, and while I did succeed in making my hacks work for an editor, I can't make it work for a property drawer since I can't find a way to change the SerializedProperty to think its underlying type is that of the deriving class that's actually there instead of the base class that's listed where the property is declared.
Any idea how I can do this?

smoky radish Sep 8, 2019, 7:23 AM

private readonly GenericMenu.MenuFunction2 _onSelectedScriptableObject = OnSelectedScriptableObject;

#

In this code OnSelectedScriptableObject must be static function ?

#

@void crag I'm interested to know how you have achieved that hack way.

#

@void crag Can you explain your problem clearly ?

visual stag Sep 8, 2019, 7:28 AM

#

It does need to be static, yes

smoky radish Sep 8, 2019, 7:32 AM

#

What is the reason ?

#

@visual stag

visual stag Sep 8, 2019, 7:36 AM

#

variable/member initialisers are called before the constructor

#

nothing exists at that point except static stuff

smoky radish Sep 8, 2019, 7:37 AM

#

So if I assign it in its constructor I don't need to make it static ?

#

@visual stag

visual stag Sep 8, 2019, 7:38 AM

#

Yes, it's just a delegate

smoky radish Sep 8, 2019, 7:38 AM

#

Another question if you have time to answer it :D
And if you want

#

https://bitbucket.org/rotorz/classtypereference-for-unity/src/master/Assets/ClassTypeReference/Editor/ClassTypeReferencePropertyDrawer.cs

#

In this code, why he used static for all of the functions ?

#

Is it right to do that ?

visual stag Sep 8, 2019, 7:39 AM

#

🤷 it really doesn't matter

#

there's a very rare performance increase

#

it's not important either way

#

It's more a code quality problem, and that's highly specific to what an API looks like. They probably made some stuff static so it could be shared between drawers

#

and everything needed to be static to support that

#

that type map thing is probably the part they wanted to cache I imagine

#

Anyway, I gtg 👋

smoky radish Sep 8, 2019, 7:44 AM

#

@visual stag
Because I did that approach and I just found out one problem in my property drawer code. That GetScriptableObjects() was just called for first the propertyAttaribute in my code.```cs
private static List<ScriptableObject> _scriptableObjects = new List<ScriptableObject>();

public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
{
if (_scriptableObjects.Count == 0)
{
GetScriptableObjects(property);
}
}

private static ScriptableObject[] GetScriptableObjects(SerializedProperty property)
{
Type propertyType = GetPropertyType(property);
Debug.Log(property.name + " " + propertyType);
string[] guids = AssetDatabase.FindAssets(String.Format("t:{0}", propertyType));
for (int i = 0; i < guids.Length; i++)
{
_scriptableObjects.Add(AssetDatabase.LoadAssetAtPath(AssetDatabase.GUIDToAssetPath(guids[i]), propertyType) as ScriptableObject);
}

return _scriptableObjects.ToArray();

}```

When projectChanged is raised is there any way to have PropertyDrawer's SerializedProperty ?

void crag Sep 8, 2019, 7:15 PM

#

@smoky radish I'll explain my problem using the actual objects in question from my project so we can use actual names, but the same problem exists for other types in my project and I'd like a general solution.
I have a base, abstract class called CutsceneEvent.
Three classes derive from it, called DelayEvent, ObjectMovementEvent and CameraShakeEvent.
Now, unsurprisingly, I have a class called Cutscene which has a list of CutsceneEvents.
What I want is to be able to add items to this list in the editor.
Each item on this list should have a dropdown selection for the type of the event, corresponding to the classes: "Delay", "Object Movement" and "Camera Shake."
Once you select a type, I want the element for which you selected it to expand and show the various data fields that the event you chose requires.
For example, a DelayEvent has a duration parameter, whereas an ObjectMovementEvent has a movableObject and a trargetPosition parameters.
If you change an event entry from one type to the other, the display in the editor should change from the previous data fields to the new ones.
If you change back, it would be mildly nice if it retained the previous values, but that is very insignificant and I don't really care one way or the other if it does that or not.

cedar reef Sep 8, 2019, 7:21 PM

#

You could just use an abstract CutsceneEvent class that inherits from ScriptableObject, and have different classes that inherit from that class for your different events

#

Then you edit your events on your ScriptableObjects, and add them to the level's list of events

#

Then you'd be working with OOP and Unity, rather than against them

void crag Sep 8, 2019, 7:38 PM

#

My CutsceneEvent class already does inherit from ScriptableObject already, and the different events each inherit from CutsceneEvent.
But now what?
I have a MonoBehaviour script with an array of CutsceneEvents in it.
How do I fill it?
It won't let me drag the DelayEvent file, for example, from the project window to an element in the array (where it currently says "None (Cutscene Event).")
If I try to add it to the game object itself it gives me an error saying that the script needs to derive from MonoBehaviour.
Now, I could do that.
I could make them all MonoBehaviours, add them all to the game object, then drag them into the array.
But that seems just really messy.
These values are only meaningful as part of that array.
Having them on the object clutters it up, and is really inconvenient in general.
If I decide I want to replace some with others, I need to delete them from the object - and make sure I have the right ones, since the array only shows the type of the script and if I have several it's up to me to know which one I placed where - and add others in their place, and then manually order them to make sure that I do indeed know which entry corresponds to which script.

@void crag You need to create an instance of your class. An easy way to do this is like this:

[CreateAssetMenu(menuName = "CutsceneEvent/FadeEvent")]
public class FadeEvent : CutsceneEvent
{
}

#

Then you can right click in the project window and create an instance of your class through the "Create" menu

#

Then you'll be able to add that object to your list.

void crag Sep 8, 2019, 10:21 PM

#

@cedar reef I see what you mean.
Didn't know about that, so it's good to learn, but it still leaves me with a less-than-optimal solution.
If I make a cutscene with various delay events in it, I need to make a DelayEvent object for each one.
This seems like it's putting me on the way to make a big mess out of my project folder.

cedar reef Sep 8, 2019, 10:22 PM

If you need to delay different amounts of time every time, that is a little annoying

@void crag Hey there,
I'm not sure if I understand what you want to do very clearly but recently I was working on implementing editor code which I can select Type in dropdown menu and show its fields by using this PropertyAttribute (https://bitbucket.org/rotorz/classtypereference-for-unity/src/master/)
Unfortunately seems Unity has many problems in its serialization system. I needed to store one instance of the selected type to prevent changing field values but because System.Object is not serialized by Unity or base class (Like abstract class or normal class) is desterilized according to the base type (No polymorphism support by Unity) so I didn't have any success in implementing it. The last thing which I wanted to check was Json serialization which I gave up to check.
Right now for my situation I'm using ScriptableObject and dropdown menu which I created for it (Working on making it better)

#

Also thanks for the code.

#

Guys any chance to access the property of PropertyDrawer or its attribute after EditorApplication.projectChanged is raised ?

void crag Sep 9, 2019, 3:26 PM

#

I'm considering taking what I did and making a generic version of it, but what I have in mind at the moment won't work for classes that inherit from MonoBehaviour or ScriptableObject since for some reason the SerializedProperty.NextVisible() method doesn't return any children when the property type inherits from those classes (whether I give it true or false for its enterChildren argument).
Any idea why?

And an even more important question: is there a way to take a SerializedProperty with a specific underlying type and change that underlying type?
Naturally, I want to change it from the base class it currently sees its serialized property as and change it to a deriving class.

meager mountain Sep 9, 2019, 4:35 PM

Hey guys, I'm having a serialization issue. https://gyazo.com/e25ff93737621060edda939d131f94f4 I have this scriptable objects that contain a list of a custom class, in that custom class one of the field is also another scriptable object. What happens is whenever I turn off unity and then open it and load the file assigning it to the list, all the Blocks go missing (the other fields are fine). In the list they all reference the single .asset file on the left but it seems that I'm missing a step into serialization somehow.

ScriptableObjects/MonoBehaviours are pretty much fully serializable by Unity, with some limitations

buildingSystem.tileCollection.tileMapCollection.Clear()
Is tileCollection just a List, or is it a custom class?

#

yep! cause position value and layer index get correctly loaded in

cedar reef Sep 9, 2019, 5:02 PM

It's just the blocks that aren't

#

Is SerializedScriptableObject some sort of Odin-specific class?

#

Or one of your own?

it's odin specific, but I was trying with normal scriptable objects and had the same

#

thought maybe that would solve it

cedar reef Sep 9, 2019, 5:08 PM

#

Ah, I see...I should have known this, but I avoid JsonUtility because Unity's serialization is crap

#

https://docs.unity3d.com/ScriptReference/JsonUtility.FromJson.html

Only plain classes and structures are supported; classes derived from UnityEngine.Object (such as MonoBehaviour or ScriptableObject) are not.

You could store the path to the ScriptableObject, if it was in a Resources folder, and load it using Resources.Load

@stark geyser @cedar reef looks like that actually came in handy to solve my issue! After doing the initial setup I then do this on my LoadMap function

#


    for(int i = 0; i < gardenSlots.tileMapCollection.Count;i++)
            {
                LoadAssetFromRef(gardenSlots.tileMapCollection[i].assetReference.LoadAsset<GardenBlock>(), gardenSlots.tileMapCollection[i].block);
               
            }

    private void LoadAssetFromRef(AsyncOperationHandle<GardenBlock> operation, GardenBlock block)
    {

        block = operation.Result;
        
    }

took me a while to understand the whole thing but glad I managed

Random question, would it be considered bad practice to use reflection in a editor tool you plan to sell, to access Unity's internal methods/classes?

prisma chasm Sep 10, 2019, 5:25 PM

#

it's not the worst sin

#

but it means it's going to be more fragile/likely to break

#

since Unity's developers aren't obligated to maintain that functionality/compatibility in the same way they are with public signatures

#

I wouldn't kick an asset store out of my project for using reflection in the way you're describing tho

gloomy chasm Sep 10, 2019, 5:30 PM

#

Okay, yeah that is kind of what I was thinking. I want to hook in to some of the same methods that the unity prefab sceneview does. But the ones I need are all internal for some unknown reason :/

prisma chasm Sep 10, 2019, 5:32 PM

#

should stick a support request asking for them to consider making it public while you're at it

gloomy chasm Sep 10, 2019, 5:34 PM

#

a comment in the code on one of the classes says that they plan to make it more generic so it can be used for other things. But that they didn't have time before release. Though it couldn't hurt to do a support request as well

cedar reef Sep 10, 2019, 5:37 PM

#

Not really an issue as long as you make sure you test that specific code against all the newest Unity releases when they come out

#

Only real difference is that with the public APIs they're generally guaranteed not to be removed or have their signature changed

prisma chasm Sep 10, 2019, 5:41 PM

#

or rather, it's a contract with the Unity developers that say they'll mark it obsolete for a little bit before they completely gut it 😄

cedar reef Sep 10, 2019, 5:42 PM

#

I think even when they mark something obsolete, they wait a good long time before removing it completely, but yeah, you get more warning with the public stuff

#

But it shouldn't be an issue as long as you stay on top of testing reflection stuff to make sure it's current

prisma chasm Sep 10, 2019, 5:43 PM

#

yah

gloomy chasm Sep 10, 2019, 5:45 PM

#

Alright, thanks guys. That is sort of what I was thinking, as long as I keep testing with the newest stuff that it should be fine.
Now I just gotta re-dig through the code to make sure the stuff I need is generic enough that I can use it 😛

gloomy chasm Sep 11, 2019, 12:26 AM

It ended up being really easy to override the sceneview. Just 2 calls, and one is just to get a bit nicer lighting.
However I have been trying to override the Hierarchy for like 5+ hours now. Even just trying to make it so it doesn't show any GameObjects, nothing. The thing refuses to bend to my will!

idk how to use though, and docs should include examples,

basically in my event, i want to invoke range of things, but bools that i want to work as toggle, with this i can achieve that?

waxen sandal Sep 11, 2019, 7:17 AM

#

Not sure what you're trying to do

sinful inlet Sep 11, 2019, 7:17 AM

#

@visual stag

visual stag Sep 11, 2019, 7:20 AM

#

If you want to toggle the boolean used by the persistent listener from the editor you can use that method.
The complex part would be to get the UnityAction<bool> used by the original method

sinful inlet Sep 11, 2019, 7:21 AM

#

basically i have to endup multiple events

#

as i want to trigger other things too beside bool

#

or have to dedicate function somewhere

visual stag Sep 11, 2019, 7:27 AM

#

I'm struggling to figure out what you want to do exactly

#

but you could use SerializedProperties

#

and go into m_PersistentCalls, which are a PersistentCallGroup, then m_Calls which are a List<PersistentCall>, then m_Arguments which is a ArgumentCache, where you then just toggle m_BoolArgument

#

I'd consider that being a lot easier than messing around with the reflection I think you'd need to do otherwise

sinful inlet Sep 11, 2019, 7:38 AM

#

the thing is, as you can see in image above, i am just toggling gameobject/components On or Off with that event, but inspector just allows me to permanently set true or false on those, the best easiest away for me is to create script for that, no big deal, but i am asking here just incase better alternative within inspector.

visual stag Sep 11, 2019, 7:39 AM

#

Are you asking how to make an event that you pass a boolean from code instead?

sinful inlet Sep 11, 2019, 7:41 AM

#

nope, i know how to, but i dont want to make event just specific to bool only, but i want that event to make bool true if it was previously false and vise versa

visual stag Sep 11, 2019, 7:43 AM

#

There is no such event, sorry

sinful inlet Sep 11, 2019, 7:43 AM

#

basically i have a button when i click game object enabled, then again i click gameobject disable

i can do this with script not a problem, thanks :), i was just wondering if inspector allows that (such a simple thing)

Well... I am officially sad. So I can set the SceneView to render the scene I want (like how prefab editing works). But I can't seem to find a way to override the hierarchy (like the prefab mode) or how to detect when the scene is about to change. So I can't do some sort of window to ask the user if they wan to save first... :/

cedar reef Sep 11, 2019, 6:48 PM

#

Have you tried https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager-sceneUnloaded.html ?

gloomy chasm Sep 11, 2019, 6:50 PM

#

Thanks @cedar reef sadly that only is called when you actually change scenes. Where what I (and prefab) does is just sort of set what is rendering with a PreviewScene.

#

I can do a check to see if the currently rendered scene is my custom scene. But I can't really check before a scene change. So I can't really do a popup window that say something like "Do you want to save changes before exiting?"
Then of course there is the hierarchy.

#

I could just make custom window that has a 'sceneview' and a hierarchy....?

visual stag Sep 11, 2019, 7:34 PM

#

You could start with making an OnOpenAsset attribute as a bit of a cheat

gloomy chasm Sep 11, 2019, 7:40 PM

#

What do you mean?

#

Oh, so that works partway at least. Though it seems opening a prefab doesn't call it.

#

There is public event Action<StageNavigationItem, StageNavigationItem> stageChanging; in an internal class. Which I think is called when going into the prefab mode. But both of it's parameters are also internal so I have no idea how to us reflection on it :/

cedar reef Sep 11, 2019, 8:06 PM

#

You can get a type by it's full assembly name, if you have to

#

https://docs.microsoft.com/en-us/dotnet/api/system.type.gettype?view=netframework-4.8#System_Type_GetType_System_String_

gloomy chasm Sep 11, 2019, 8:08 PM

#

Yeah, my problem is that to assign a method or action or something I am pretty sure it needs to have the types as parameters. But if both parameter types are internal...

cedar reef Sep 11, 2019, 8:09 PM

#

That's what Type.GetType is for, it returns a Type

gloomy chasm Sep 11, 2019, 8:10 PM

But you can't do private void MyMethod(assemblyClassBlaBla.GetType() stageNavigationItem) {}

cedar reef Sep 11, 2019, 8:12 PM

#

Oh, I see what you mean, that's tricky

You could generate the method using reflection, though

    private Action<ActionTestClass> testAction;

    public void TestActionAction(object testAction)

        testAction += TestActionAction;
        testAction(new ActionTestClass());

Interesting, didn't realize an Action could be used like an event. I tested it with an event

#

What you want to subscribe to above is an event, though

#

Although I didn't test with an event using an Action like that

gloomy chasm Sep 11, 2019, 8:26 PM

#

Now I will go read how to add actions to an event with reflection on the small chance that this will work and give me a message before changing to prefab.
And if it does, then all that is left is to figure out if I can move or turn off the rotation gizmos on the top right, and figure out how the prefab takes over the hierarchy, hope that it isn't in native code, or in direct calls in OnGUI that I can't hook in to...

What will be the syntax for

{ Do this }
Please help me laughing

Thanks @polar stone I hope this helps me

polar stone Sep 13, 2019, 4:54 AM

#

There's a pretty good example of basic buttons.

#

After that, calling your Animation.Play() or analogue should be easy

thin fractal Sep 13, 2019, 4:57 AM

#

Ok I read it but this I know already
I just want to know how to make a button click event and how to put that in a if statement

#

Btn1.OnClick<>

#

Something like that

polar stone Sep 13, 2019, 4:58 AM

#

What are you actually trying to do?

#

Ah wait

#

I see what you're talking about

#

K so

#

In the example

#


public class ExampleScript : MonoBehaviour
{
    // Draws a button with an image and a button with text
    Texture tex;

    void OnGUI()
    {
        if (!tex)
        {
            Debug.LogError("No texture found, please assign a texture on the inspector");
        }

        if (GUILayout.Button(tex))
        {
            Debug.Log("Clicked the image");
        }
        if (GUILayout.Button("I am a regular Automatic Layout Button"))
        {
            Debug.Log("Clicked Button");
        }
    }
}```

#

See where it says Debug.Log("Clicked Button")?

#

You would replace that with your Animation.Play() analogue

#

Do you actually understand how OnGUI() works?

#

Yes, you do use the if statement in Unity - my fault, I was thinking of classic C#/Winforms for some reason

#

        {
            Debug.Log("Clicked Button");
        }```

#

That shows a button with a label with the string that's passed to Button(). When it's clicked, the code inside is executed.

#

Do you understand?

thin fractal Sep 13, 2019, 5:17 AM

#

Yeah things are bit clear now

#

Should I send you a part of my code so that you could tell me where is the fault in my script

#

What if I have 4 different takes in the controller and Take001 to Take 004 can I command that if Button 1 is clicked play take 001 only and button 4 is clicked play take 004 only
All the takes are mute as I want the user to select what they want to play by clicking specific buttons

#

I mean, sure, you can post your code

thin fractal Sep 13, 2019, 5:25 AM

i'm haveing issues with a custom editor window... if i start up the unity project everything is fine until i've opend the custom window for the first time... then, everytime i change a script and go back to unity(that is, it recompiles) the mouse starts to flicker dapidly back and fourth between the normal mouse pointer and the loading circle. this goes on for about 2 to 3 minutes before it finishes compiling and everything goes back to normal until i recompile again or restart unity. it's extremely anying and it makes it hard to rapidly debug it. this is what i know so far: 1.the profiler shows nothing out of normal while i'm debuging the editor. 2. when the compilation is done the custom window works just fine 3.it continues to do it even after i've closed the custom window 4.i've got multiple assembly defenitions throughout the project so that shouldn't be the issue. anyone got any ideas of what could be wrong or of what to try?

cedar reef Sep 13, 2019, 3:44 PM

@cedar reef when you said "keeping a reference to the window somewhere else in memory actually keeps the window from properly reloading" do you mean outside the class? the assembly? or where?

Outside the instantiated object of the class, I think I found that event subscriptions were the worst culprit

Unity's smart enough to set references to a UnityEngine.Object to null, but not to track down events that have subscriptions from that object

jaunty furnace Sep 13, 2019, 4:09 PM

#

for what i'm trying to to to be fesible i need more than the main class, would something like nested classes be okay?

cedar reef Sep 13, 2019, 4:10 PM

#

Should be, I've had trouble debugging the exact problem when that happens

jaunty furnace Sep 13, 2019, 4:20 PM

#

@cedar reef i tried both nesting all the other classes in the main window and replaceing the events with Action but no luck, anyhing else you could suggest trying?

cedar reef Sep 13, 2019, 4:22 PM

#

An Action you subscribe to is still an event, it's just syntax sugar. I generally follow a pattern of subscribing to the assembly reload events and clearing all my subscriptions before the reload and renewing them afterward

#

Although I can't guarantee that that's even what's going on with your problem

jaunty furnace Sep 13, 2019, 4:24 PM

#

i'll try that then...

#

btw, how do i access the assembly reload events?

#

no worries, found the events...

#

nope... didn't work. the events might not be the issue then?

cedar reef Sep 13, 2019, 4:38 PM

#

Quite possibly

jaunty furnace Sep 13, 2019, 4:41 PM

#

@cedar reef is there no way to profile the issue?

#

how did you discover it from the begining?

chilly stone Sep 13, 2019, 4:45 PM

#

Guys is there a way to write custom editor variable, where you can drag scripts from project view, and it would only take a name of that script?

jaunty furnace Sep 13, 2019, 4:47 PM

#

@chilly stone can't you just do .name on the asset you get?

chilly stone Sep 13, 2019, 4:48 PM

#

@jaunty furnace is there an Asset type?

#

I'm new to editor scripting, never knew about those

jaunty furnace Sep 13, 2019, 4:50 PM

#

no, there's no such thing as a "Asset" as you say. though, when you make the object field you get a unity "Object" back... all instances of Object has a .name property. that contains the name of the object, in this case the file name of the asset

chilly stone Sep 13, 2019, 4:51 PM

#

@jaunty furnace what about this one? https://docs.unity3d.com/ScriptReference/VersionControl.Asset.html

jaunty furnace Sep 13, 2019, 4:52 PM

#

never heard about that one before though it seems like it belongs to version control. it's not the thing you want to use

chilly stone Sep 13, 2019, 4:53 PM

#

Ok I'll try using Object fields, thanks

jaunty furnace Sep 13, 2019, 5:18 PM

#

@cedar reef i don't know if you saw what i asked above but i wonderd how you first found the problem. since theyre similar if not the same problem i figure i may find my problem by hearing about how you solved yours...

cedar reef Sep 13, 2019, 5:36 PM

#

A lot of trial and error, basically

cloud wedge Sep 13, 2019, 6:57 PM

#

I've written this code to create a custom inspector. Once I get the index of the selected questData, how do I assign it back to the property? https://pastebin.com/zNKcdGKP

Pastebin

// This code is part of the Fungus library (http://fungusgames.com...

#

I can't do this because it's read only: questDataProp.serializedObject.targetObject = ...

#

found the answer

#

this library I'm using has a really convenient method I can use instead of all that work

#

fungus has a method like this:

            CommandEditor.ObjectField<QuestData>(questDataProp,
                                                new GUIContent("Quest", "The quest to start. The first entry (if it exists) will be added to the quest log."),
                                                new GUIContent("<None>"),
                                                allQuestData);

#

very convenient

How should I use the CustomPropertyDrawer properly ?

[CustomPropertyDrawer(typeof(Test))]
public class TestEditor : PropertyDrawer
{
   public override float GetPropertyHeight(SerializedProperty property, GUIContent label)

       return 16f * 2;
   }
   public override void OnGUI(Rect rect, SerializedProperty property, GUIContent label)
   {
       var positive_activator = property.FindPropertyRelative("positive_activator");
       var negative_activator = property.FindPropertyRelative("negative_activator");

       float pa = positive_activator.floatValue;
       float na = negative_activator.floatValue;

       EditorGUILayout.MinMaxSlider( ref na, ref pa, -1, 1 );

       Rect rect1;

       EditorGUI.MinMaxSlider( rect, "?", ref na, ref pa, -1, 1 );

       positive_activator.floatValue = pa;

Property Drawers

Hello!

I was wondering if there's a (new? better?) way to implement property drawers using UIElements instead of the good ol' IMGUI.

Thanks!

tough cairn Sep 14, 2019, 6:29 PM

#

there is also an example on the official docs :
https://docs.unity3d.com/ScriptReference/PropertyDrawer.html

Thbaks @cedar reef and @tough cairn

feral karma Sep 14, 2019, 6:50 PM

@fleet summit note that what the docs only partially mention is that UIElements drawers will only work if you also have a custom inspector that uses UIElements.

tough cairn Sep 14, 2019, 7:15 PM

#

I have solved my problem it seems that negative infinity was breaking the EditorGUILayout.MinMaxSlider

tough cairn Sep 14, 2019, 7:46 PM

#

how do i save a SerializedProperty after calling GUIUtility.ExitGUI() ?

#

https://i.imgur.com/HCW2Fb3.gifv

Imgur

#

im using EditorGUILaytout inside CustomPropertyDrawer

#

using GUIUtility.ExitGUI() will prevent the jumping, but it won't set the value

tough cairn Sep 14, 2019, 8:29 PM

#

huh... i commented everything out recompiled and it solved itself ... IMGUI is a strange animal

tough cairn Sep 14, 2019, 8:47 PM

#

nvm ... its back

#

ok wtf the exact same code will sometimes work perfectly / result in random jumping / won't even render due to error at index 0 position ...

#

Guess its time to learn UI Elements

tough cairn Sep 14, 2019, 10:06 PM

How can i get the label value in CreatePropertyGUI ?
like its done in OnGUI(Rect rect, SerializedProperty property, GUIContent label)

Is there a way to dynamically create property drawers?

cloud wedge Sep 16, 2019, 3:37 AM

I'm new to inspector editors. Is there a better way to write this code?

            if (t.questData != null)
            {
                int currentIndex = t.questData.steps.IndexOf(t.questStep);
                int stepIndex = EditorGUILayout.Popup(currentIndex,
                    t.questData.steps.ToArray()
                );
                if (stepIndex == -1)
                {
                    t.questStep = null;
                }
                else
                {
                    t.questStep = t.questData.steps[stepIndex];
                }
            }

#

questStep is a string.

visual stag Sep 16, 2019, 3:38 AM

#

Almost everything could be cached

#

I wouldn't be doing a ToArray every repaint unless you had to

#

same with the index lookup

cloud wedge Sep 16, 2019, 3:42 AM

#

ah. Is there a way to turn this into a one liner?

#

or close to it?

#

I feel like this is a lot of if statements

visual stag Sep 16, 2019, 3:43 AM

#

well, why would stepIndex be -1 ever?

#

oh, because you're doing weird stuff

cloud wedge Sep 16, 2019, 3:44 AM

#

when you pick the quest (not shown here), the questStep popup will default to a blank

#

so then I think stepIndex would be -1

visual stag Sep 16, 2019, 3:44 AM

#

I would usually cache an array with a None string as 0

cloud wedge Sep 16, 2019, 3:45 AM

#

I"m down to do that, but wouldn't it still return -1?

visual stag Sep 16, 2019, 3:45 AM

#

No, because you would keep track of currentIndex and initialise it as 0

#

only the popup and the initialisation would set it, it would never be anything that wasn't in the popup array

cloud wedge Sep 16, 2019, 3:46 AM

#

oh i don't know how this works. I thought if I hardcoded it to 0, then that would mean every pass, it would reset the value of the dropdown to the 0-ith display value in the array

visual stag Sep 16, 2019, 3:48 AM

#

usually I would have something like:

using(var cCS = new EditorGUI.ChangeCheckScope()){
    index = EditorGUILayout.Popup(index, options);
    if(cCS.changed){
        if(index == 0)
            SetThingToNull();
        else
            SetThingToRealIndex(index - 1);
    }
}```

cloud wedge Sep 16, 2019, 3:49 AM

#

where do you initialize index?

visual stag Sep 16, 2019, 3:50 AM

#

and in Enable or something:

options = new string[realOptions.Count+1];
options[0] = "None";
for(int i = 0; i < realOptions.Count; i++){
    options[i+1] = realOptions[i].label;
}
index = realOptions.IndexOf(current) + 1;

#

if that makes any sense, obviously it won't compile 😛

cloud wedge Sep 16, 2019, 3:53 AM

#

so that second example is where the index is initialized?

visual stag Sep 16, 2019, 3:53 AM

#

yup

#

and where the options array is cached

#

It obviously depends on how frequent things change, like if you're altering the list you'd have to re-cache and initialise

Quick question. I just found GUILayout.VerticalScope, is there some reason not to use this? It seems like it makes code with lots of Begin/EndVertical way more readable.

wispy delta Sep 16, 2019, 5:11 PM

#

@gloomy chasm Using scopes is better than calling the Begin/End. They look cleaner and you can't fail to close them

#

I think most people just don't use them because they don't know about them or don't know about using(...) statements

gloomy chasm Sep 16, 2019, 5:13 PM

#

Yeah, they seem way better. I have just never seen anyone use or even mention them before, so I wanted to see if there was some performance reason or something I wasn't thinking of.

@whole steppe To override an animated transform value you have to set it's rotation via script in the LateUpdate method. LateUpdate is called after animator is resolved. (https://docs.unity3d.com/ScriptReference/MonoBehaviour.LateUpdate.html).

A regular class

I already placed that attribute

whole steppe Sep 19, 2019, 1:53 PM

You can't just have a class in your editor

#

It needs to be attached to something that is viewable in the editor

#

Some prefab

#

Or scene object

chilly stone Sep 19, 2019, 2:24 PM

#

@whole steppe why? I'm just using it as a data holder, it doesn't need to be attached

whole steppe Sep 19, 2019, 2:28 PM

#

Data holder for what? Afaik, you can't just have some class floating around

#

Either it's used somewhere in-game on some object

#

Or it's stored as an asset

#

If you want to hold data, as some stored variables, that's what scriptableobjects are for

I'd rather write my own inspector extension than override it, considering you probably have few uses cases for this where overriding script affect every use case

@tough cairn You can store a reference to the thread when you create it

I believe Unity reloads the domain when entering play mode so I'm not sure if the reference will persist. Lemme know if I'm wrong tho @cedar reef

Pretty sure you're correct about that

@tough cairn Isn't there some API for finding processes tho? You could just look for it before creating it kinda like a singleton

                    ProcessThreadCollection threads = p.Threads;
                    foreach( var t1 in threads )
                    {
                        Thread t2 = ( Thread ) t1;
                    }

and it seems like there are 0 threads in current process

#

but i can still see it in the task manager

cedar reef Sep 20, 2019, 5:24 PM

#

If I remember right, when I was playing with multithreading and Unity, not actually stopping threads when playmode was exited wound up with them just existing off in limbo still doing their thing, rather than stopping and being destroyed

tough cairn Sep 20, 2019, 5:47 PM

@cedar reef that's sort of what happens now, for example if i run ping 20 times it will be alive until the command is complete, or if its waiting for user input it will get stuck there forever

    {
        // get all fields on this node
        fields = instance.GetType().GetFields();
        if (fields.Length == 0) return;

        // for each field
        foreach (var fieldInfo in fields)
        {
            // if this field is of type scriptable object
            if (fieldInfo == typeof(ScriptableObjectVariable))
            {
                Debug.Log("Found a field of SO to load");
                ScriptableObjectVariable soVar = fieldInfo.GetValue(this) as ScriptableObjectVariable;

                soVar.OnGraphEnd();
            }
        }
    }

#

Seems this does not work, via reflection. Because type ScriptableObjectVariable is a base class

#

Can reflection only find child classes via this method?

#

Ive investigated if there was a way to identify the field by an interface instead, but haven't been able to get that to work either.

chilly stone Sep 21, 2019, 11:33 AM

#

@cyan sphinx this is not really an editor question, but you can use:

typeof(ScriptableObjectVariable).IsAssignableFrom(fieldInfo.GetType())

cyan sphinx Sep 21, 2019, 11:48 AM

@chilly stone , thank you. Working on an editor script (posting here every few days 🙂 ) and this seems to be the only channel that knows about reflection

@heady magnet if you ping all objects one by one, all will be "expanded" even if only the latest is actually highlighted, so that you at least see all things in your selection.

visual stag Sep 23, 2019, 5:31 PM

#

If you make a component script anything that is serializable can be assigned in the script's importer as a default

#

so you could assign a material there

#

and it would be added by default

whole steppe Sep 23, 2019, 5:54 PM

#

Hm, not sure I get you right, but if that script is a monobehaviour, you could try the ExecuteInEditmode (https://docs.unity3d.com/ScriptReference/ExecuteInEditMode.html) parameter and do the set up in the awake method, possibly wrapped in an #if UNITY_EDITOR ifdef

#

Kind of hard to tell what exactly is going on, but I'd assume a) the script inherits from the graphic class https://docs.unity3d.com/2018.1/Documentation/ScriptReference/UI.Graphic.html and then sets a specified material when it is being added (likely in the way I mentioned above)

whole steppe Sep 23, 2019, 6:25 PM

#

what does the default material have to do with this?

#

if you have a reference to a material inside the script, then that's it. You can drag and drop it but that won't by itself change anything else.

whole steppe Sep 23, 2019, 6:45 PM

#

Ah, I think I get what you're saying now. What I think is going on in the video, is that the default graphic material was changed (https://docs.unity3d.com/2018.1/Documentation/ScriptReference/UI.Graphic-defaultGraphicMaterial.html) [EDIT: Actually, just watched it again - no, probably not, sorry, it's probably just the defaultMaterial property of the graphic]
But that probably won't help with your use-case - a shader that renders shadows in the UI. I think you'll need to create a specific material for that, sorry.

#

Seeing how shaders are very closely tied to materia.s

#

materials*

#

I assume your main motivation behind not changing the material is that you want your UI shadow casting to work with 'any material'?

#

okay. Well, as you can see, the material on the GameObject is switched out when he attaches that component. So I'd assume he set the defaultMaterial in the properties of the script.

#

You can do that by clicking on your MonoBehaviour (the asset, the one in the project view) once, you can set default values there.

#

Maybe that does the trick?

#

But then again, if you want it to be a generic shadow solution, you shouldn't do that in a MonoBehaviour that inherits from Graphic (because otherwise you couldn't use it with any other type of graphic such as image or button)

#

what exactly are you trying to do anyway?

whole steppe Sep 23, 2019, 7:56 PM

Wondering if anyone around here has dealt with an issue I'm running into. I've got a custom class that's not inheriting from monobehavior or scriptable object, but it is seralized by unity. I'm trying to access an array of this custom class via SeralizedProperty but I can't seem to cast the reference value to the class...I.E. CustomBlockClass block = blocksProperty.GetArrayElementAtIndex(i).objectReferenceValue as CustomBlockClass; I've been googling and not finding anything solution wise.

#

Surely there must be a way to do it?

radiant sinew Sep 26, 2019, 9:45 PM

objectReferenceValue returns a unity object

#

not .netobject

#

so that cast will always fail

I created a custom reorderablelist for a scriptableobject. But when i change value in this list the field instant reset to 0 ```var element = m_list.serializedProperty.GetArrayElementAtIndex(index);
var elementObj = new SerializedObject(element.objectReferenceValue);

    var propertyIterator = elementObj.GetIterator();

    EditorGUI.LabelField(new Rect(rect.x + EditorGUIUtility.fieldWidth,
                                rect.y + 2,
                                rect.width,
                                EditorGUIUtility.singleLineHeight),
                        element.objectReferenceValue.name);
    var idx = 0;

    while (propertyIterator.NextVisible(true))
    {
        if (propertyIterator.name == "m_Script") continue;
        idx++;
        EditorGUI.PropertyField(new Rect(rect.x,
                                        rect.y + (m_lineHeight * idx),
                                        rect.width, EditorGUIUtility.singleLineHeight),
                                propertyIterator);
    }``` im using the property iterator. Any idea ?

#

so the scriptableObject contains a ReorderableList out of other scriptableObjects but instead of a object filed i just show the target scriptableObject fields

uncut snow Sep 28, 2019, 6:57 AM

does anyone have an idea ?

hey, I hate to bother people by asking for help, but I've been working on this all day and I think I'm misunderstanding something, so I was hoping someone could point me to the right documentation or something.

#

I followed a guide (not entirely, deviated a bit for my needs) to build a node editor window (EditorWindow) with OnGUI, and I've added serialization of the node graph into ScriptableObjects with save and load buttons, but I'd really like the editor to support Unity serialization with undo functions and what not since this node editor is going to be pretty important in my project. For custom editors, I simply use SerializedObjects & SProperties and let unity handle the rest, but since I'm modifying a SO with an EditorWindow and not extending Editor, I'm not really sure where to go from here

@quiet solstice you can use Undo.RecordObject

Those "Stat" like "AttackDamage" is also a scriptableObject

#

private void DrawElementCallback(Rect rect, int index, bool isactive, bool isfocused)
    {
        var element = m_list.serializedProperty.GetArrayElementAtIndex(index);
        var elementObj = new SerializedObject(element.objectReferenceValue);


        var propertyIterator = elementObj.GetIterator();

        EditorGUI.LabelField(new Rect(rect.x + EditorGUIUtility.fieldWidth,
                rect.y + 2,
                rect.width,
                EditorGUIUtility.singleLineHeight),
            element.objectReferenceValue.name);
        var idx = 0;

        while (propertyIterator.NextVisible(true))
        {
            if (propertyIterator.name == "m_Script") continue;
            idx++;
            EditorGUI.PropertyField(new Rect(rect.x,

                propertyIterator);
        }
        
    }``` Thats the part where the elements get drawn.

visual stag Sep 29, 2019, 8:20 AM

When you draw the list do you call scriptableObject.ApplyModifiedProperties afterwards?

uncut snow Sep 29, 2019, 8:21 AM

#

public override void OnInspectorGUI()
    {
        serializedObject.Update();
        SerializedProperty iterator = serializedObject.GetIterator();

        while (iterator.NextVisible(true))
        {
            if ("m_Script" == iterator.propertyPath) continue;

            if (!iterator.propertyPath.Contains("Stats"))
            {
                EditorGUILayout.PropertyField(iterator, true);
            }
        }

        if (m_property.objectReferenceValue != null)
        {
            m_list.DoLayoutList();
        }

        serializedObject.ApplyModifiedProperties();
        EditorUtility.SetDirty(target);
    }```

visual stag Sep 29, 2019, 8:22 AM

don't set the target as dirty

uncut snow Sep 29, 2019, 8:22 AM

#

ok

visual stag Sep 29, 2019, 8:22 AM

#

Also you need to ApplyModifiedProperties on elementObj in the first one

#

and likely Destroy it too

uncut snow Sep 29, 2019, 8:24 AM

#

the elementObj ?

visual stag Sep 29, 2019, 8:25 AM

#

Actually, just Dispose

@visual stag Thanks the ApplyModifiedProperties on elementObj was the part i'd miss. Big thanks !

Another question. I'm writing a property Drawer for cs public class StatCollection { public List<BaseStat> Values = new List<BaseStat>(); } polymorphy list is atm not supported so i use scriptableobjects atm. To add a specific ScriptableObject i need access the List from SerializedProperty property. I can use m_property.FindPropertyRelative("Values") and use InsertArrayElementAtIndex() but it just creates a copy of the base class which is not what i want. Is there any workaround to solve this ?

Hi, have a problem with editorwindow. I made a window to have quick items there and I want to drag out them if I need it. So I this works. For example. I drag the GUI.Layout(image) (which gives me the pointed Object on drag event) and I can move it to folder from A to B. But if I want to drag again it says.. the Object path cannot be found (it shows me the path to A which is wrong). So if I go to folder B and move the object back to A.. now the EditorWindow things my object is now in B which is again wrong. I don't get it why. I have gify to make it easier to understand.

Can you share some code?

rare surge Sep 30, 2019, 12:41 PM

#

I miss one step there

#

This is for the drag and drop

switch (ev.type)
            {
                case EventType.MouseDrag:
                    Debug.Log("PrepareStartDrag");
                    // Clear out drag data
                    
                    DragAndDrop.activeControlID = 0;
                    DragAndDrop.objectReferences = dragableObjects;
                    foreach(var o in DragAndDrop.objectReferences)
                    {
                        Debug.Log(o);
                    }

                    Debug.Log("StartDrag");
                    // Start the actual drag
                    DragAndDrop.StartDrag("Dragging title");

                    // Make sure no one uses the event after us
                    Event.current.Use();

                    
                    break;
                case EventType.DragExited:
                    DragAndDrop.PrepareStartDrag();
                    Repaint();
                    Event.current.Use();
                    break;
                default:
                    break;
            }

This is how I draw and make interactable (this contains the logic for drag out)

                    GUILayout.Label(previewTexture, GUILayout.MaxWidth(maxWidth), GUILayout.MaxHeight(maxHeight));
                    InteractHandler(i);

What happens if you ask the AssetDatabase for the path to your dragableObject?

rare surge Sep 30, 2019, 1:10 PM

#

I would like to check. My problem is I haven't any detection if the object is dropped somewhere. If the cursor leaves the window eventtype is DragExited. I cannot even check MouseUp. I tried Update and EditorApplication.update too.

waxen sandal Sep 30, 2019, 1:10 PM

#

Checking when you start the drag is fine

rare surge Sep 30, 2019, 1:15 PM

#

Yea I did. The path is correct. Weird

#

After moving it it shows the correct path.

#

Maybe I use just the path for the drag and drop and not objectReferences

#

Even while I am dragging it it says correct path.. but why after dropping it says file not found lol. Could it be a bug?

#

With DragAndDrop.paths + AssetDatabase.GetAssetPath it works perfectly

This may sound stupid but are there any extensions/plugins/assets that i can use to help sort out my Shop? I have had troubles in the past with setting up a simple mechanism where the player "buys" stuff, and that stuff gets added to the "inventory". Preferably something that already has save files handled.

I was working with Godot on a match 3 game and I quit making it when some code I couldn't find was saving the contents of the "Inventory" incorrectly, causing the player to lose stuff they had bought, and gaining stuff they hadn't bought yet. I know it was probably some stupid mistake on my part, but if I can avoid that happening again that would be great. It's a simple thing, so simple that it's basically not even worth programming, as it doesn't impress the employers.

Whew, it was a long battle, but I've got Unity adding and switching out property drawers at run-time. This way, I don't have to use attributes, and I can do stuff like making inherited classes use the same property drawer as their base class without having to add an attribute to the drawer for each inherited class

orchid prism Oct 2, 2019, 8:19 PM

Made My first PropertyDrawer. I'm happy with how it turned out but I don't have the ability to adjust the value with the mouse anymore, and I don't know what that feature is called so googling it has had no good results

📎 Screen_Shot_2019-10-02_at_3.17.39_PM.png

#

anyone know how I can allow Min and Max to be adjusted via mouse drag?

#

similar to Vector2

#

or if anyone knows where I can find Unity's native PropertyDrawers then I could just study those

cedar reef Oct 2, 2019, 8:48 PM

#

@orchid prism Are you drawing your fields using EditorGUI.PropertyField?

#

For the basic fields, I believe rendering them is C++ code that you can't get at. You can take a look through https://github.com/Unity-Technologies/UnityCsReference/tree/master/Editor/Mono/GUI

orchid prism Oct 2, 2019, 9:05 PM

#

each min and max are a PrefixField and a FloatField

#

I got weird results from using PropertyField but I can take another look

#

ah

#

with PropertyField I didn't know how to control the field size and label size

cedar reef Oct 2, 2019, 9:08 PM

#

You can draw it without a label and make your own label, if you need

orchid prism Oct 2, 2019, 9:08 PM

#

Ignore that Max is disabled*
min is created via PropertyField, Max is separate fields

📎 Screen_Shot_2019-10-02_at_4.07.56_PM.png

#

oh thats what I'm doing but I don't have float adjustment control

#

I'm not familiar with accepted terms here, so when i say float adjustment I mean how i can drag a float's label and drag to adjust it's value

cedar reef Oct 2, 2019, 9:11 PM

#

I mean you can draw it as a PropertyField with no label, and you should get the sliding behaviour you're looking for

orchid prism Oct 2, 2019, 9:12 PM

#

hmm

#

tried

EditorGUI.PropertyField(rect, minProperty, null);

cedar reef Oct 2, 2019, 9:13 PM

#

EditorGUI.PropertyField(position, property, GUIContent.none)

orchid prism Oct 2, 2019, 9:13 PM

#

ah

#

it doesn't allow drag when there's no label

cedar reef Oct 2, 2019, 9:15 PM

#

Dragging behaviour works fine for me using PropertyField, so it could be a bug in a different version of Unity. I'm on 2019.1.14f

orchid prism Oct 2, 2019, 9:15 PM

#

2019.2.7f2

#

I'm doubtful that it changed between these

cedar reef Oct 2, 2019, 9:16 PM

#

Stuff breaks between versions, regression bugs happen

orchid prism Oct 2, 2019, 9:16 PM

#

it's possible, yeah, but I'm just doubtful

#

it works with EditorGUI.PropertyField(rect, minProperty);

#

but then it looks like garbage

cedar reef Oct 2, 2019, 9:17 PM

You can control the label width manually

EditorGUIUtility.labelWidth

#

Just be sure to change it back to 0 or the value it previously had when you're done with it

dim walrus Oct 3, 2019, 9:36 AM

#

Hmm if there is no cases but the scenes that the instance id is negative, you may use that to check you are drawing the scene icon

#

But i'm not so sure about that

#

Or better, if the InstanceIDToObject returns null

frigid lava Oct 3, 2019, 9:42 AM

#

Yeah, but I don't want to draw the icon on every scene, only those who meet a condition. Maybe I can figure out which scene it is by keeping a counter and checking that against currently loaded scenes
