通过设置相机的Viewport Rect 来实现,将下面的脚本挂在相机上，设置enabled=true就可实现屏幕震动效果。

using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
     
    public class ShakeCamera : MonoBehaviour {
     
    	public float shakeLevel = 3f;// 震动幅度
    	public float setShakeTime = 0.5f;	// 震动时间
    	public float shakeFps = 45f;	// 震动的FPS
     
    	private bool isshakeCamera = false;// 震动标志
    	private float fps;
    	private float shakeTime = 0.0f;
    	private float frameTime = 0.0f;
    	private float shakeDelta = 0.005f;
    	private Camera selfCamera;
     
    	 void OnEnable()
    	{
    		isshakeCamera = true;
    		selfCamera = gameObject.GetComponent<Camera>();
    		shakeTime = setShakeTime;
    		fps = shakeFps;
    		frameTime = 0.03f;
    		shakeDelta = 0.005f;
    	}
     
    	void OnDisable()
    	{
    		selfCamera.rect = new Rect(0.0f, 0.0f, 1.0f, 1.0f);
    		isshakeCamera = false;
    	}
    		
    	// Update is called once per frame
    	void Update()
    	{
    		if (isshakeCamera)
    		{
    			if (shakeTime > 0)
    			{
    				shakeTime -= Time.deltaTime;
    				if (shakeTime <= 0)
    				{
    					enabled = false;
    				}
    				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);
    					}
    				}
    			}
    		}
    	}
    }
