untiy中让物体bird具有拖尾效果

1.首先在工程中导入资源： Pocket RPG Weapon Trails.unitypackage（此资源里带有脚本WeaponTrail.cs）,资源见链接：[https://download.csdn.net/my][https_download.csdn.net_my]

2.给物体bird添加脚本TestMyTrail.cs,代码如下

3.在物体bird下面添加空物体trail，并给trail添加脚本WeaponTrail.cs和组件MeshRenderer

public class TestMyTrail : MonoBehaviour {
    
        public WeaponTrail myTrail;
    
        private float t = 0.033f;
        private float tempT = 0;
        private float animationIncrement = 0.003f;
    
        void LateUpdate()
        {
            t = Mathf.Clamp(Time.deltaTime, 0, 0.066f);
    
            if (t > 0)
            {
                while (tempT < t)
                {
                    tempT += animationIncrement;
    
                    if (myTrail.time > 0)
                    {
                        myTrail.Itterate(Time.time - t + tempT);
                    }
                    else
                    {
                        myTrail.ClearTrail();
                    }
                }
    
                tempT -= t;
    
                if (myTrail.time > 0)
                {
                    myTrail.UpdateTrail(Time.time, t);
                }
            }
        }
        void Start()
        {     
            myTrail.SetTime(0.0f, 0.0f, 1.0f);// 默认没有拖尾效果
        }
    
        public void StartTrails()  //开始进行拖尾
        {   
            myTrail.SetTime(2.0f, 0.0f, 1.0f);//设置拖尾时长
            myTrail.StartTrail(0.5f, 0.4f);
        }
    
        public void ClearTrails()    //清除拖尾
        {
            myTrail.ClearTrail();
        }
    }
