Hey guys, i’m learning about Custom Editor and I need some help. Im trying to display another enum depending the option of the first enum. The code below “works”, the second enum appears in the inspector but I can not change him.

using UnityEngine;
using System.Collections;
using UnityEditor;

[CustomEditor(typeof(RoomFeatures)), CanEditMultipleObjects]
public class PropertyHolderEditor : Editor {

	public SerializedProperty 
		roomType_Prop,
		corridorType_Prop,
		roomExit_Prop,
		entrance_Prop,
		exit_Prop;

	void OnEnable () {
		// Setup the SerializedProperties
		roomType_Prop = serializedObject.FindProperty ("roomType");
		corridorType_Prop = serializedObject.FindProperty ("corridorType");
		roomExit_Prop = serializedObject.FindProperty ("roomExit");
		entrance_Prop = serializedObject.FindProperty ("entrance");
		exit_Prop = serializedObject.FindProperty ("exit");

	}
	
	public override void OnInspectorGUI() {
		serializedObject.Update ();
		
		EditorGUILayout.PropertyField(roomType_Prop);

		RoomFeatures.RoomType rt = (RoomFeatures.RoomType)roomType_Prop.enumValueIndex;
		RoomFeatures.CorridorType ct = (RoomFeatures.CorridorType)corridorType_Prop.enumValueIndex;

		switch( rt ) {
		case RoomFeatures.RoomType.Corridor:
			ct = (RoomFeatures.CorridorType)EditorGUILayout.EnumPopup ("Corridor Type:", ct);
			break;

		case RoomFeatures.RoomType.Room: 
			EditorGUILayout.PropertyField( roomExit_Prop, new GUIContent("Exit") );
			break;
		}
		
		
		serializedObject.ApplyModifiedProperties ();
	}
}

And this is the RoomFeatures script:

using UnityEngine;
using System.Collections;

[System.Serializable]
public class RoomFeatures : MonoBehaviour 
{
	public enum RoomType {Corridor, Room, BossRoom};
	public RoomType roomType;

	public enum CorridorType {Small, Long, VeryLong}
	public CorridorType corridorType;

	public bool roomExit = false;

	[System.Serializable]
	public class entrance
	{
		public enum Vertical {Left, Middle, Right};
		public enum Horizontal {Top, Center, Bot};
	}

	[System.Serializable]
	public class exit
	{
		public enum Vertical {Left, Middle, Right};
		public enum Horizontal {Top, Center, Bot};
	}
}

Any help will be welcome, sorry if my english is not very good.

You need to display the second enum (corridorType_Prop) in the same way you display the first enum (roomType_Prop); with the EditorGUILayout.PropertyField. Right now you are just changing the local variable ct which will fall out of scope after the OnInspectorGUI function.
