在做unity的入门练习

LevelScript.js

#pragma strict var experience : int; function Level() : int { return experience / 750; }

LevelScriptEditor.js

#pragma strict @CustomEditor (LevelScript) class LevelScriptEditor extends Editor { function OnInspectorGUI() { var myLevelScript : LevelScript = target; myLevelScript.experience = EditorGUILayout.IntField("Experience", myLevelScript.experience); EditorGUILayout.LabelField("Level", myLevelScript.Level().ToString()); } }

（视频用的是c#，不过我比较熟悉javscript,就用了javascript的格式）

虽然最后程序成功了，但是unity报了警告有点在意。有人知道是什么意思么？

Assets/Editor/LevelScriptEditor.js(8,42): BCW0028: WARNING: Implicit downcast from 'UnityEngine.Object' to 'LevelScript'.
