如何在Unity中制作二维闪烁灯？

Question

我需要帮助，谢谢。我只需要制作闪烁的 2Dlight（使用 Universal Pipeline）。一段时间后，灯开始闪烁并且 returns 回到其原始值 (light.intensivity = 0.36f)，一段时间后他又开始闪烁。但是用这个糟糕的代码我不能那样做，闪烁只起作用，因为协程每次重新启动（StartCoroutine（LightFlicker（））; 在协程中）。但我不知道如何制作这个东西。也许使用其他方法来闪烁光？

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Rendering;
using UnityEngine.Experimental.Rendering.Universal;
using UnityEngine.Experimental;

using UnityEngine.Experimental.Rendering.LWRP;



public class FlickeringLight : MonoBehaviour {
    public UnityEngine.Experimental.Rendering.Universal.Light2D renderLight;
    public AudioSource AS; // AudioSource to play the audio.
    public AudioClip LightAudio; // Audio to play. 
    [SerializeField] float firstValue = 0f;
    [SerializeField] float secondValue = 0.36f;
    [SerializeField] float secondsBetweenFlickers = 2f;

    void Start ()
    {
        renderLight.intensity = renderLight.intensity;
        StartCoroutine(LightFlicker());
    }
    private void Awake()
    {
    renderLight = GetComponent<UnityEngine.Experimental.Rendering.Universal.Light2D>();
    }

    IEnumerator LightFlicker()
    {    
            renderLight.intensity = Random.Range(firstValue, secondValue);
            yield return new WaitForSeconds(secondsBetweenFlickers);
            AS.PlayOneShot(LightAudio); // Play the audio.
            StartCoroutine(LightFlicker());
    }

    //failed try to pause Coroutine LightFLicker
   /* IEnumerator TimerLight()
    {
        StopCoroutine(LightFlicker());
        renderLight.intensity = 0.36f;
        yield return new WaitForSeconds(3f);
        StartCoroutine(LightFlicker());
     
    }
   */
   
}```

添加一个 while 循环以永不停止协程

IEnumerator TimerLight()
{
    while (true)
    {
        renderLight.intensity = Random.Range(firstValue, secondValue);
        yield return new WaitForSeconds(secondsBetweenFlickers);
    }
}

那你可以试试随机等待时间

IEnumerator TimerLight()
{
    while (true)
    {
        renderLight.intensity = Random.Range(firstValue, secondValue);
        var randomTime = Random.Range(0, secondsBetweenFlickers);
        yield return new WaitForSeconds(randomTime);
    }
}

也许您有时需要某种移动平均线来使其平滑。

private Queue<float> queue; // TODO: initialize
private int smoothing = 5;

IEnumerator TimerLight()
{
    var sum = 0f;

    while (true)
    {
        while (queue.Count > smoothing)
        {
            sum -= queue.Dequeue();
        }
        var newValue = Random.Range(firstValue, secondValue);
        queue.enque(newValue);
        sum += newValue;
        renderLight.intensity = sum / queue.Count;

        yield return new WaitForEndOfFrame();
    }
}

我还没有测试过这段代码，但它应该几乎可以正常工作。因为我以前使用过这个移动平均队列来统一闪烁光。我认为它是运行每一帧...
