我们UI自适应采用的是Canvas Scaler 设置 Expand模式。 那么UI可以很好的自适应屏幕，可是粒子特效就会出问题所以写下了这个脚本来自适应UI的粒子特效。
比如技能图标的特效光圈。
当屏幕缩放后，UI变小了，可是特效出问题了。
测试环境unity5.3.5
代码如下所示：
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class UIParticleScale : MonoBehaviour {
private List<ScaleData> scaleDatas = null;
void Awake()
scaleDatas = new List<ScaleData>();
foreach( ParticleSystem p in transform.GetComponentsInChildren<ParticleSystem>(true)){
scaleDatas.Add(new ScaleData(){transform = p.transform,beginScale = p.transform.localScale});
void Start ()
float designWidth = 1136;//开发时分辨率宽
float designHeight = 640;//开发时分辨率高
float designScale = designWidth/designHeight;
float scaleRate = (float)Screen.width/(float)Screen.height;
foreach(ScaleData scale in scaleDatas)
if(scale.transform != null){
if(scaleRate<designScale)
float scaleFactor = scaleRate / designScale;
scale.transform.localScale = scale.beginScale * scaleFactor;
}else{
scale.transform.localScale = scale.beginScale;
#if UNITY_EDITOR
void Update () {
Start(); //Editor下修改屏幕的大小实时预览缩放效果
#endif
class ScaleData
public Transform transform;
public Vector3 beginScale = Vector3.one;
欢迎大家测试～
