c#脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PoleMove : MonoBehaviour
{//移动上限制public float up;//移动下限public float below;//速度private float speed;// Start is called before the first frame updatevoid Start(){speed = Random.Range(0.5f, 2.5f);}// Update is called once per framevoid Update(){if (transform.position.y>up){speed = -speed;}if (transform.position.y < below){speed = -speed;}//让柱子上限移动transform.position = new Vector3(transform.position.x, transform.position.y + speed * Time.deltaTime, transform.position.z);}
}

创建空的图层，并把柱子拖拽到同个图层下

给pole拖拽添加脚本
