每秒激活和停用 GameObject

Question

我想制作一个物体 - 龙头，它会在 5 秒内和每 3 秒内爆发一次火焰。但我不确定该怎么做...我的脚本实际上是这样的：

using UnityEngine;
using System.Collections;

public class Dragon_Head_statue: MonoBehaviour {

public GameObject openFire;

private bool IsActive;

void Update()
{
    Invoke("OpenFire", 4);
}

void OpenFire()
{
    IsActive = !IsActive;
    openFire.SetActive(IsActive);
}

}

所以现在它的工作方式就像它开始燃烧，然后循环激活和停用...所以它不会起作用。我还尝试了其他东西，比如协程，InvokeRepeating 没有成功。

协程配合new WaitForSeconds(3.0f)完美解决这个问题。看看这段代码：

using UnityEngine;
using System.Collections;

public class Dragon_Head_statue: MonoBehaviour {
    public GameObject openFire;
    public bool IsActive = false; //IsActive means here that we're in a loop bursting flames, not that we're currently not bursting flames.

    void Start()
    {
        //Start the coroutine
        //5 seconds flame burst, then wait 3 secs
        StartCoroutine(OpenFire(5.0f, 3.0f)); 
    }

    /* function for making this thing stop */
    void StopFlames()
    {
        //Stop the first running coroutine with the function name "OpenFire".
        StopCoroutine("OpenFire");
        IsActive = false; //propage this metadata outside
        //Additionally turn of the flames here if we were just 
        //in the middle of bursting some 
        openFire.SetActive(false);
    }

    IEnumerator OpenFire(float fireTime, float waitTime )
    {
        IsActive = true; //For outside checking if this is spitting fire
        while(true)
        {
            //Activate the flames
            openFire.SetActive(true);
            //Wait *fireTime* seconds
            yield return new WaitForSeconds(fireTime);
            //Deactivate the flames 
            openFire.SetActive(false);      
            //Now wait the specified time
            yield return new WaitForSeconds(waitTime);
            //After this, go back to the beginning of the loop
        }
    }

}

你用StartCoroutine启动协程，然后你可以再次通过函数名停止协程。您也可以先将 OpenFire 返回的 IEnumerator 保存到局部变量中，如果您不喜欢输入字符串，则对该变量使用 StopCoroutine。
