老师我给bird加了7个trail 然后复制了7给材质球 想给小鸟加个彩虹屁 所以把TestMyTrail里的weapontrail改成了List  但结果导致资源包里的weapon trial脚本不能修改trail的大小了

Mytrail代码段

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

public class TestMyTrail : MonoBehaviour
{
    private static TestMyTrail _Instance2;
    void Awake()
    {
        _Instance2 = this;
    }
    //public WeaponTrail myTrail;
    public List<WeaponTrail> Trail;

    private float t=0.033f;
    private float tempT = 0;
    private float animationIncrement = 0.003f;

     void LateUpdate()
     {
        t = Mathf.Clamp(Time.deltaTime,0,0.66f);
        if (t > 0)
        {
            while (tempT < t)
            {
                tempT += animationIncrement;

                for (int i = 0; i < Trail.Count; i++)
                {
                    if (Trail[i].time > 0)
                    {

                       Trail[i].Itterate(Time.time - t + tempT);
                    }
                    else
                    {
                        Trail[i].ClearTrail();
                    }
                }        
            }
            tempT -= t;
            for (int i = 0; i < Trail.Count; i++)
            {
                if (Trail[i].time > 0)
                {
                    Trail[i].UpdateTrail(Time.time, t);
                }
            }
            
        }
     }
    void Start()
    {

        // 默认没有拖尾效果
        for (int i = 0; i < Trail.Count; i++)
        {
            Trail[i].SetTime(0.0f, 0.0f, 1.0f);
        }
        
    }

    public void StartTrails()
    {
        for (int i = 0; i < Trail.Count; i++)
        {
            //设置拖尾时长
            Trail[i].SetTime(2.0f, 0.0f, 1.0f);
            //开始进行拖尾
            Trail[i].StartTrail(0.5f, 0.4f);
        }
       
    }

    public void CleanTrails()
    {
        //清除拖尾
        for(int i=0;i<Trail.Count;i++)
        Trail[i].ClearTrail();
    }
}

彩虹屁  太大了 如果强行重合就变成白色了=。=  差了半天网上也没有
