unity 遍歷 go 的一些方法

// 能找到所有的root go節點
GameObject[] allGos = UnityEngine.SceneManagement.SceneManager.GetActiveScene().GetRootGameObjects();

// 找不到隱藏的go
GameObject[] allGos = (GameObject[])UnityEngine.Object.FindObjectsOfType(typeof(GameObject));

// 連隱藏的go都能找到
GameObject[] pAllObjects = (GameObject[])Resources.FindObjectsOfTypeAll(typeof(GameObject));
