EditorGUILayout.Popup has always the same value selected

Got problem with custom inspector popup list ( drop down ).

Code (CSharp):

1. [CustomEditor(typeof(FieldPrefab))]
2. public class CustomFieldInspector : Editor {
3.  
4.     public int index = 0;
5.     public Texture TextureColor;
6.  
7.     public override void OnInspectorGUI() {
8.         string[] options = new string[]{ "Red", "Yellow", "Green" };
9.         var MyObject = target as FieldPrefab;
10.  
11.         index = EditorGUILayout.Popup("Field type:", index, options, EditorStyles.popup);
12.         switch(index) {
13.             case 0: TextureColor = (Texture)Resources.Load("Textures/Red"); break;
14.             case 1: TextureColor = (Texture)Resources.Load("Textures/Yellow"); break;
15.             case 2: TextureColor = (Texture)Resources.Load("Textures/Blue"); break;
16.         }
17.         MyObject.renderer.sharedMaterial.SetTexture("_MainTex", TextureColor);
18.  
19.     }
20. }

Changing color works fine, but when I change the color of one object, on editor window take another and come back to this first he get's again first texture from list. So, the point is what is the method for catching current field state and set as value.

 

I don't think you can save a variable in a class derived from Editor like this. You'll have to create an integer called index in your FieldPrefab-script and access it from your custom inspector script.

Code (CSharp):

1. myObject.index = EditorGUILayout.Popup("Field type:", myObject.index, options, EditorStyles.popup);

 

I seem to have the same problem, but your suggestion doesn't seem to work
My Code:

myClass.SelectedGroupIndex = EditorGUILayout.Popup(myClass.SelectedGroupIndex, myClass.GroupNames);

Index always stays 0. I found out that after this line the index is correct, but in the next OnGUI() iteration everything is 0 again. And yes this is the only code that touches the classes SelectedGroupIndex. I'm lost.

Plot Twist: The class had been overridden the whole time. ._.
