PrefabUtility.ResetToPrefabState

説明

コンポーネントやゲームオブジェクトのプロパティーを親プレハブの状態にリセットします

All overrides will be cleared. However the transform.position and rotation of a root game object in a prefab instance will never be cleared.

// Try to set the selected GameObject to a prefab state

@MenuItem("Examples/Attempt to reset to prefab %r")
static function Reset() {
    if(PrefabUtility.ResetToPrefabState(Selection.activeGameObject))
        Debug.Log("Reseted to prefab state successfully!");
    else
        Debug.LogError("Couldnt reset to a prefab state " + Selection.activeGameObject.name);
}

@MenuItem("Examples/Attemp to reset to prefab %r", true)
static function CheckReset() {
    return Selection.activeGameObject != null;
}
