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);
}
}
}
