该博客介绍了Unity中实现UI网格特效根据屏幕尺寸自动适配的脚本。通过`UIGridRenderingScale`类，脚本遍历所有子粒子系统，记录初始缩放比例，并在启动时根据设计分辨率与实际屏幕比例调整粒子系统的大小，确保在不同设备上视觉效果一致。适用于移动端和桌面端游戏开发中的UI适配问题。

一、渲染脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

// 网格特效渲染
public class UIGridRenderingScale : MonoBehaviour
{
    private List<ScaleData> scaleDatas = new List<ScaleData>();
    private void Awake()
    {
        foreach (ParticleSystem p in transform.GetComponentsInChildren<ParticleSystem>(true))
        {
            scaleDatas.Add(new ScaleData() { transform = p.transform, beginScale = p.transform.localScale});
        }
    }
    // Start is called before the first frame update
    void Start()
    {
        float designWidth = 1080;
        float designHeight = 1920;
        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();
    }
#endif
    class ScaleData {
        public Transform transform;
        public Vector3 beginScale = Vector3.one;
    }
}
