Unity教程之-Unity3d实现屏幕抖动效果

很多游戏玩家游戏死亡时一般都需要屏幕抖一下下或者屏幕变灰。为了在unity3d中实现这个特效，百度了下相关写法，发现方法很多~~~，找来找去，找到个简单粗暴地，啥都不需要，通过Camera Viewpoint实现 一个脚本拖动到Camera上就可以了，略微修改了一点点，share一下，下面是代码

using UnityEngine;
using System.Collections;

public class ShakeCamera : MonoBehaviour
{

// 震动标志位
private bool isshakeCamera = false ;

// 震动幅度
public float shakeLevel = 3f;
// 震动时间
public float setShakeTime = 0.2f;
// 震动的FPS
public float shakeFps = 45f;

private float fps;
private float shakeTime = 0.0f;
private float frameTime = 0.0f;
private float shakeDelta = 0.005f;
private Camera selfCamera;

void Awake()
{
selfCamera = GetComponent();
}

// Use this for initialization
void Start()
{
shakeTime = setShakeTime;
fps = shakeFps;
frameTime = 0.03f;
shakeDelta = 0.005f;
}

// Update is called once per frame
void Update()
{
if (isshakeCamera)
{
if (shakeTime > 0)
{
shakeTime -= Time.deltaTime;
if (shakeTime <= 0)
{
selfCamera.rect = new Rect(0.0f, 0.0f, 1.0f, 1.0f);
isshakeCamera = false ;
shakeTime = setShakeTime;
fps = shakeFps;
frameTime = 0.03f;
shakeDelta = 0.005f;
}
else
{
frameTime += Time.deltaTime;

if (frameTime > 1.0 / fps)
{
frameTime = 0;
selfCamera.rect = new Rect(shakeDelta * (-1.0f + shakeLevel * Random.value), shakeDelta * (-1.0f + shakeLevel * Random.value), 1.0f, 1.0f);
}
}
}
}
}

public void shake()
{
isshakeCamera = true ;
}
}
