Unity自定义编辑器预设显示修改的值

我有一个预置,包含一个自定义编辑器脚本。然后在场景中修改预置,包括脚本本身。

但是,在预置之外修改的变量看起来就像其他变量一样。 Undo.RecordObject 和 EditorUtility.SetDirty 但运气不好。

我已经搜索和测试脚本几个小时没有运气,如果有人能告诉我我做错了什么就太好了。

编辑器脚本如下所示:

using UnityEditor;
using UnityEngine;
using UnityEditor.SceneManagement;
using UnityEngine.SceneManagement;

[CustomEditor (typeof (MyScript))]
[CanEditMultipleObjects]
public class MyScriptEditor : Editor {

    SerializedProperty usePanel, [...], equalHints;

    protected virtual void OnEnable () {
        setvars ();
    }
    void setvars () {
        usePanel = serializedObject.FindProperty ("usePanel");
        // ...and more variables...
        equalHints = serializedObject.FindProperty ("equalHints");
        MyScript s = (MyScript) target;
        Undo.RecordObject (s, "test");
    }

    public override void OnInspectorGUI () {
        if (usePanel.Equals (null)) setvars ();
        MyScript s = (MyScript) target;
        if (GUI.changed) {
            EditorUtility.SetDirty (s); // <--- this was one of my attempts
            EditorSceneManager.MarkSceneDirty (SceneManager.GetActiveScene ());
        }

        usePanel.boolValue = EditorGUILayout.Toggle ("Use Panel", usePanel.boolValue);
        // some more lines of code here
        if (equalHints.boolValue) {
            // do some stuff
        }
        this.serializedObject.ApplyModifiedProperties ();
    }
}
