一,使用velocity方法移动角色;
二,使用localScale,使x等于负数实现图片反转;
三,m_rg.velocity = 数值*方向;
using System.Collections; using System.Collections.Generic; using UnityEngine; public class PlayerController : MonoBehaviour { private Rigidbody2D m_rg; public float MoveSpeed; void Start () { m_rg = gameObject.GetComponent<Rigidbody2D>(); } // Update is called once per frame void Update () { //------------------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); } } }
