添加游戏对象以永久列出问题

Question

我有一个预制件，我正在将其添加到一个列表中，其中包含用于游戏功能的时间安排。但是它永远不会停止添加游戏对象。

在 addToPath() 中，for 循环每 2 秒生成 1 个对象，但如果我将其更改为任何其他数字，例如 total，这就是我想要的总量在列表中，它将每 2 秒添加一次。

 public class FollowPath : MonoBehaviour
{
    public int total;
    public GameObject enemyAi;

    public List<GameObject> enemy;
    private IEnumerator coroutine;

    // Start is called before the first frame update
    void Start()
    {
        print("Starting " + Time.time);


        addToPath(enemyAi);
    }

    private void addToPath(GameObject ai) {
        for (int i = 0; i < 1; i++)
        {
            StartCoroutine(WaitAndPrint(2.0f, ai));
            print("Before WaitAndPrint Finishes " + Time.time);
        }  
    }

    // every 2 seconds perform the print()
    private IEnumerator WaitAndPrint(float waitTime, GameObject ai)
    {
        while (true)
        {
            yield return new WaitForSeconds(waitTime);
            print("WaitAndPrint " + Time.time);
            enemy.Add(ai);
            // Works for Object in Scene and Prefabs
            Instantiate(enemy[enemy.Count - 1], new Vector3(1, 1, 1), Quaternion.identity);

        }
    }


}

我看不清楚你在这里要做什么，但问题是WaitAndPrint 永远不会完成，它有一个while (true) {...} 不允许它终止。循环没有产生对象，WaitAndPrint 是。

你可能想要的是这个：

public class FollowPath : MonoBehaviour
{
    public int total;
    public GameObject enemyAi;

    public List<GameObject> enemy;
    private IEnumerator coroutine;

    // Start is called before the first frame update
    void Start()
    {
        print("Starting " + Time.time);


        StartCoroutine(addToPath(enemyAi));
    }

    private IEnumerator addToPath(GameObject ai) {
        for (int i = 0; i < 1; i++)
        {
            yield return new WaitForSeconds(waitTime);
            WaitAndPrint(2.0f, ai);
            print("Before WaitAndPrint Finishes " + Time.time);
        }  
    }

    private void WaitAndPrint(float waitTime, GameObject ai)
    {
        print("WaitAndPrint " + Time.time);
        enemy.Add(ai);
        // Works for Object in Scene and Prefabs
        Instantiate(enemy[enemy.Count - 1], new Vector3(1, 1, 1), Quaternion.identity);

    }
}
