How to use coroutines in Editor derrived script?

Unity Engine
1

Hi,
I wanted to make a cursor system for unity and made this script to extend the editor of a ScriptabeObject. It should preview the frames of the animated cursor by looping through the array where they are stored. (the array is contained in the ScriptableObject) Now here’s my problem: I’d like to use coroutines for timing & looping through the array, but the StartCoroutine() method doesn’t seem to be available in Editor derrived scripts. Is there sth. i am missing? Or do they just don’t work in Editor scripts?

using System.Collections;
using UnityEditor;
using UnityEngine;

[CustomEditor(typeof(CursorObject))]
public class CursorEditorPreview : Editor
{
    CursorObject cursorObject;

    int currentFrame = 0;

    void OnEnable()
    {
        cursorObject = target as CursorObject;
    }

    public override void OnInspectorGUI()
    {
        base.OnInspectorGUI();
        if (cursorObject.frames == null)
        {
            return;
        }

        StartCoroutine(LoopAniamtion());
    }

    IEnumerator LoopAniamtion()
    {
        if(currentFrame == cursorObject.frames.Length - 1)
        {
            currentFrame = 0;
        }

        Texture2D texture = AssetPreview.GetAssetPreview(cursorObject.frames[0]);
        GUILayout.Label("Preview", GUILayout.Height(80), GUILayout.Width(80));
        GUI.DrawTexture(GUILayoutUtility.GetLastRect(), texture);

        currentFrame++;

        yield return new WaitForSeconds(1 / cursorObject.frameRate);

        StartCoroutine(LoopAniamtion());
    }
}

It’s possible to do coroutines in the editor. Google it up. I think it’s a package you can get from the UPM

Yes, I tried that, but I was having problems
S but StartCoroutine() still wasn’t possible.

Then read the documentation properly: Class EditorWindowCoroutineExtension | Editor Coroutines | 1.0.0
