UnityはHierarchyパネルの特殊なオブジェクトの特殊な識別を処理します.

次の効果を実現するには、主に特殊なオブジェクト(または特殊なコンポーネントを持つオブジェクト)を識別します.

実装方法はUnityのいくつかのイベントを傍受することです
  EditorApplication.hierarchyWindowChanged += HierarchyWindowChanged; EditorApplication.hierarchyWindowItemOnGUI += HierarchyWindowItemOnGUI;
このクラスがAssetPostprocessorの派生クラスであることを示す必要があります.
リソースインポート後の処理クラスは、ここであまり時間のかかる操作を行わないほうがいいです.そうしないと、Unityエディタはカートンします.プリコンパイルとインポート処理を実行してエディタの右下隅に小さな円があってから、長い間カートンに移籍します.
