任何让我的脚本等待几秒钟的方法吗？

Question

我正在制作无尽的亚军游戏，我希望我的代码的一部分等待几秒钟，我该怎么做？问题在于，当新地形的开始边缘碰到相机视图的底部时，它将删除地形。

 void Start()
{
    StartCoroutine(Example());
}

IEnumerator Example()
{

    yield return new WaitForSeconds(5);

}
}

这是我希望回收平台功能在几秒钟后执行的代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlatformManager : MonoBehaviour
{
[SerializeField]
private GameObject[] _platformPrefabs;
[SerializeField]
private int _zedOffset;


// Start is called before the first frame update
void Start()
{
    for (int i = 0; i < _platformPrefabs.Length; i++)
    {
        Instantiate(_platformPrefabs[i], new Vector3(0, 0, i * 4), Quaternion.Euler(0, 90, 0));
        _zedOffset += 4;
    }
}
// i want this to wait
public void RecyclePlatform(GameObject Platform)
{
    Platform.transform.position = new Vector3(0, 0, _zedOffset);
    _zedOffset += 4;

}



}

recyclePlatform函数在执行之前需要等待

Answer 1

如果您只是想让线程等待-

System.Threading.Thread.Sleep(milliseconds); 

Answer 2

将其转换为Unity Coroutine。

private IEnumerator RecyclePlatform(GameObject Platform)
{
    yield return new WaitForSeconds(numSecondsToWait); # we can use floats to specify more accurate times
    Platform.transform.position = new Vector3(0, 0, _zedOffset);
    _zedOffset += 4;
}

然后我们随时随地开始这样的例程。

StartCoroutine(RecyclePlatform);

Answer 3

您可以使用它来等待您想要等待的任何功能或动作。如果要使用异步等待：

public static async void DoActionAfterSecondsAsync(Action action, float seconds)
{
    await Task.Delay(TimeSpan.FromSeconds(seconds));
    action?.Invoke();
}

如果要使用协程：

public IEnumerator void DoActionAfterSecondsRoutine(Action action, float seconds)
{
    yield return new WaitForSecondsRealtime(seconds);
    action?.Invoke();
}

我建议您为此使用实用程序类。看起来像这样。

public static class CooldownManager
{
    private class HiddenMonobehaviour : MonoBehaviour { }

    private static readonly MonoBehaviour mono;

    static CooldownManager()
    {
        GameObject obj = new GameObject("CooldownManager");
        UnityEngine.Object.DontDestroyOnLoad(obj);
        mono = obj.AddComponent<HiddenMonobehaviour>();
    }

    public static Coroutine Cooldown(float cooldownDuration, Action action)
    {
        return mono.StartCoroutine(InternalCooldown(cooldownDuration, action));
    }

    private static IEnumerator InternalCooldown(float cooldownDuration, Action action)
    {
        yield return new WaitForSeconds(cooldownDuration);
        action.Invoke();
    }
}

使用它，您可以编写：

public class Example : MonoBehaviour
{
    void Start()
    {
        Cooldown(2, () => RecyclePlatform(gameObject));
    }

    void RecyclePlatform(GameObject Platform)
    {
        Platform.transform.position = new Vector3(0, 0, _zedOffset);
        _zedOffset += 4;
    }
}

Answer 5

只需将代码放在协程中，并添加超时时间

public void RecyclePlatform(GameObject Platform)
{
    StartCoroutine(RecyclePlatformCoroutine(Platform));
}

private IEnumerator RecyclePlatformCoroutine(GameObject Platform)
{
    yield return new WaitForSeconds(5);

    Platform.transform.position = new Vector3(0, 0, _zedOffset);
    _zedOffset += 4;
}
