Unity 2D物体移动

一，设置

二，脚本

1，PlayerController 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerController : MonoBehaviour {private Rigidbody2D m_rg;public float MoveSpeed;public float JumpSpeed;//在角色下添加一个空物体//设置一个跳跃监测点public Transform CheckPoint;//设置一个跳跃监测半径public float CheckRadius;//设置一个跳跃监测层---角色与地面的检测public LayerMask WhatIsGround;//角色默认是否着地--truepublic bool isGround;private Animator Anim;//存储复活点的位置信息public Vector2 RespawnPosition;public LevelManager theLevel;void Start () {m_rg = gameObject.GetComponent<Rigidbody2D>();Anim = gameObject.GetComponent<Animator>();//游戏刚开始时，玩家的重生点，就是当前的初始位置点RespawnPosition = transform.position;theLevel = FindObjectOfType<LevelManager>();}// Update is called once per framevoid Update () {//
        isGround = Physics2D.OverlapCircle(CheckPoint.position, CheckRadius, WhatIsGround);//m_rg.gameObject.transform.rotation= Quaternion.identity;//------------------Input.GetAxisRaw没有小数值，只有整数，不会产生缓动------------------//角色水平移动//按住D键，判断如果大于0，则向右开始移动if (Input.GetAxisRaw("Horizontal") > 0){m_rg.velocity = new Vector2(MoveSpeed, m_rg.velocity.y);//设置自身缩放的值transform.localScale = new Vector2(1f,1f);}//角色水平移动//按住A键，判断如果小于0，则向左开始移动else if (Input.GetAxisRaw("Horizontal") < 0){m_rg.velocity = new Vector2(-MoveSpeed, m_rg.velocity.y);//如果new Vector2(-1f, 1f)  x值为负数，则图片进行反转显示transform.localScale = new Vector2(-1f, 1f);}else//角色水平移动//松开按键，判断如果等于0，则停止移动
        {m_rg.velocity = new Vector2(0, m_rg.velocity.y);}//角色按下空格键实现跳跃//禁止二连跳//要先判断角色是否在地面上，在地面上可以跳，不在地面上则不能跳if (Input.GetButtonDown("Jump")&& isGround){m_rg.velocity = new Vector2(m_rg.velocity.x,JumpSpeed);}Anim.SetFloat("Speed", m_rg.velocity.x);Anim.SetBool("Grouned", isGround);}private void OnTriggerEnter2D(Collider2D collision){if (collision.tag=="KillPlane"){//gameObject.SetActive(false);//使当前玩家的位置点为，保存的复活点位置//transform.position = RespawnPosition;
theLevel.Respawn();}//角色与当前的复活点进行碰撞检测//把当前角色的位置信息，设置为重生的复活点if (collision.tag == "CheckPoint"){RespawnPosition = collision.transform.position;}}/// <summary>/// 实现角色跟随移动平台一起运动/// 把角色的父物体设置为移动平台/// </summary>/// <param name="collision"></param>private void OnCollisionEnter2D(Collision2D collision){Debug.Log("碰撞到的那个吊毛叫什么名字："+ collision.gameObject.name);if (collision.gameObject.tag == "MovePlatForm"){transform.parent = collision.transform;Debug.Log("碰撞到的那个吊毛的父物体什么名字：" + transform.parent);}}private void OnCollisionExit2D(Collision2D collision){if (collision.gameObject.tag == "MovePlatForm"){transform.parent = null;}}
}

 2，MovePlatFromController 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;/// <summary>
/// 平台移动脚本
/// </summary>
public class MovePlatFromController : MonoBehaviour {//要移动的物体public GameObject PlatForm;//要移动物体开始的点public Transform StartPoint;//要移动物体结束的点public Transform EndPoint;//要移动物体的移动速度public float MoveSpeed;//要移动到的目标点public Vector2 target;void Start () {target = EndPoint.position;}// Update is called once per framevoid Update () {//把物体移动到指定的位置点上PlatForm.transform.position = Vector2.MoveTowards(PlatForm.transform.position, target, MoveSpeed*Time.deltaTime);//实现物体来回移动if (PlatForm.transform.position == EndPoint.position){target = StartPoint.position;}if (PlatForm.transform.position == StartPoint.position){target = EndPoint.position;}}
}
