unity3D 实现2D游戏背景层交错感(视觉差)

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

//图层交错效果
public class InterlacingOfLayers : MonoBehaviour
{
    public Transform Cam;                   //摄像机位置
    public float MoveRate;                  //移动幅度
    private float StartPointX, StartPointY; //开始的X点,Y点
    public bool LockY;                      //Y轴是否移动,需要Y轴移动不用勾,不需要就勾

    // Start is called before the first frame update
    void Start()
    {
        StartPointX = transform.position.x;
        StartPointY = transform.position.y;
    }

    // Update is called once per frame
    void Update()
    {
        //如果Y轴不移动
        if (LockY)
        {
            //当前挂在的对象的坐标 = 新的二维向量坐标(开始坐标 + 摄像机的x坐标 * 移动幅度 , y轴不变)
            transform.position = new Vector2(StartPointX + Cam.position.x * MoveRate, transform.position.y);
        }
        //移动X,Y轴
        else
        {
            transform.position = new Vector2(StartPointX + Cam.position.x * MoveRate, StartPointY + Cam.position.y * MoveRate);
        }
    }
}

记得将主摄像机和移动幅度设置好
