我正在尝试创建一个管理器，它通过索引＃从可能的索引列表中加载随机场景。一旦场景被加载，我想从列表中删除该项目，以消除相同的场景再次加载。一旦管理员完成了所有场景，我再次调用DoInitSceneIndexList()来创建一个填充了场景的新列表，并且该过程将重新开始。除了一件事，一切都在这里工作。每当我切换场景时，列表将再次重建，并且它从完整列表开始，而不是每次减少一个。每次加载场景时，我在哪里制作重建列表的错误？谢谢！

答案 0 :(得分：0)
为了防止每次重建List，您必须做两件事。
将以下调用添加到 ForestGameManager 的Awake（）方法中。
DontDestroyOnLoad(this.gameObject);
这样你的对象就不会在SceneChange上被销毁了。并保持直到你摧毁它或结束游戏。
使用bool检查您的GameManager是否已全部初始化
private void Start() {
if (!this._isInitialized) {
forestAnimals = new List<ForestAnimal>();
forestSceneIndexes = new List<int>();
lastForestSceneIndexNumber = ((firstForestSceneIndexNumber + numberOfForestScenes) - 1);
if (initSceneList) {
StartCoroutine(DoInitSceneIndexList());
StartCoroutine(DoGetRandomScene());
}
Debug.Log("There are " + numberOfForestScenes + " forest scenes in MasterLoader.");
this._isInitialized = true;
} else {
this.forestAnimals.Clear(); //I assume you can clear the list on scene change
}
}
