I’m working on an editor script and I need to destroy a group of transforms that are parented to a single transform. In the past, I was able to simply call DestroyImmediate(parentTransform); but I’m guessing that the new strict rules in Unity 3.4 have killed that, as that method now gives me an ‘unknown identifier’ compile error. I changed it to Object.DestroyImmediate, which allows it to compile, but when the function is called, I get a Method Not Found error. What gives?
Oh wow, that just flew over my head. My apologies.
I don’t have 3.4 yet, so I can’t do testing on my own.
The new ‘strict’ rules only apply to JavaScript in mobile (iOS or Android) projects. It sounds to me like its a bug and should be reported, but I would wait until you get a second opinion first.
For others to test (and perhaps you as well), add this code to TempEditor.cs under the Editor folder:
using UnityEngine;
using UnityEditor;
using System.Collections;
public class TempEditor : EditorWindow {
GameObject obj;
[MenuItem ("Window/TempEditor")]
static void ShowWindow () {
EditorWindow.GetWindow (typeof (TempEditor));
}
void OnGUI () {
obj = (GameObject)EditorGUILayout.ObjectField (obj, typeof (GameObject), true);
if (GUILayout.Button ("Delete")) {
if (obj != null)
DestroyImmediate (obj);
}
}
}
using UnityEngine;
using UnityEditor;
using System.Collections;
public class TempEditor: EditorWindow
{
GameObject obj;
[MenuItem("Window/TempEditor")]
static void ShowWindow()
{
EditorWindow.GetWindow(typeof (TempEditor));
}
void OnGUI()
{
obj = (GameObject) EditorGUILayout.ObjectField(obj, typeof (GameObject), true);
if (GUILayout.Button("Delete"))
{
if (obj != null)
{
DestroyImmediate(obj);
}
}
}
}
I am not too sure what you want to achieve however it works when i drag a gameObject to the field and click delete. So in Unity 3.4 there’s a need to include true/false in your editoGUILayout.
Ok, it’s a bit of an odd thing, but I found the answer in this thread: http://forum.unity3d.com/threads/86032-change-object-via-script./page2
It turns out, because I was using my own custom subclass of Object, I can’t just call Destroy() since that’s something that you only get with monobehaviour. And when I called Object.Destroy(), it thought I meant System.Object instead of UnityEngine.Object.
