我正在尝试开发我的游戏中的功能，该功能加载一个List中填充的总共8个随机场景，然后在加载场景后从列表forestSceneIndexes = new List<int>();中删除。这样当加载下一个随机场景时，它会从列表中的现有场景中选择，等等。
我要做的第一件事是使用函数填充我的列表：
private IEnumerator DoInitSceneIndexList()
{
// Initialize scene name list
for (int i = 0; i < numberOfForestScenes; i++)
{
forestSceneIndexes.Add(firstForestSceneIndexNumber + i);
Debug.Log("Scene index " + forestSceneIndexes[i].ToString() + " added to int list.");
}
yield return new WaitForEndOfFrame();
initSceneList = false;
}
之后我在函数DoGetRandomScene
中得到随机场景private IEnumerator DoGetRandomScene()
{
// Get scene name from random pick
randomSceneIndex = Random.Range(firstForestSceneIndexNumber, (firstForestSceneIndexNumber + forestSceneIndexes.Count) - 1);
yield return new WaitForEndOfFrame();
StartCoroutine(DoRemoveRandomSceneFromList());
// Load selected scene
StartCoroutine(DoLoadScene(randomSceneIndex));
}
一旦我得到随机场景，我就立即从列表中删除该索引：
private IEnumerator DoRemoveRandomSceneFromList()
{
// Remove selected scene from list
forestSceneIndexes.Remove(randomSceneIndex);
yield return new WaitForEndOfFrame();
}
然后我将randomSceneIndex传递给DoLoadScene（）函数
private IEnumerator DoLoadScene(int sceneIndex)
{
yield return new WaitForEndOfFrame();
SceneManager.LoadScene(sceneIndex, LoadSceneMode.Single);
}
我的问题是它无法正常工作，它似乎开始没有前几个场景，但它只是继续重新加载相同的场景一旦它下降到约3个场景。我不确定我的错误，任何帮助都将不胜感激！下面还添加了完整的脚本。谢谢！

除了评论中提到的问题，您应该仔细检查，问题在于您如何选择随机数。你并没有从实际的指数列表中抽出来。它应该是这样的：
np.array注意，我没有修改你对协同程序的大部分使用，但正如评论中所指出的那样，你肯定有很多需要清理的地方。
