//1.修改stone脚本的CreateTears方法

private void CreateTears(){

tearNum++;

GameObject go = Instantiate(tearsGo,roadsTrans[0].position,Quaternion.identity);

Tear tear = go.GetComponent<Tear>();

tear.pointsTrans = pointTrans;

}

//2.把眼泪的层级改成2

//3.新建脚本Tear

public class Tear：MonoBehaviour

{

public Transform[] pointsTrans;

void Update()

{

Vector2.MoveTowards(transform.position,)

}

}
