通过DirX和DirY来对吃豆人的状态机进行转变

7.吃豆人的物理化以及移动方式的选择

在吃豆人上创建PacmanMove的脚本

8.让吃豆人可以在迷宫中移动

using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    
    public class PacmanMove : MonoBehaviour
    {
        //吃豆人的移动速度
        public float speed = 0.35f;
        //吃豆人下一次移动将要去的目的地
        private Vector2 dest = Vector2.zero;
    
        private void Start()
        {
            //保证吃豆人在游戏刚开始的时候不会动
            dest = transform.position;
        }
    
        private void FixedUpdate()
        {
            Vector2 temp = Vector2.MoveTowards(transform.position, dest, speed);
            GetComponent<Rigidbody2D>().MovePosition(temp);
            if (Input.GetKey(KeyCode.UpArrow) || Input.GetKey(KeyCode.W))
            {
                dest = (Vector2)transform.position + Vector2.up;
            }
            if (Input.GetKey(KeyCode.DownArrow) || Input.GetKey(KeyCode.S))
            {
                dest = (Vector2)transform.position + Vector2.down;
            }
            if (Input.GetKey(KeyCode.LeftArrow) || Input.GetKey(KeyCode.A))
            {
                dest = (Vector2)transform.position + Vector2.left;
            }
            if (Input.GetKey(KeyCode.RightArrow) || Input.GetKey(KeyCode.D))
            {
                dest = (Vector2)transform.position + Vector2.right;
            }
        }
    }

运行程序结果如下

9.完善吃豆人的移动

using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    
    public class PacmanMove : MonoBehaviour
    {
        //吃豆人的移动速度
        public float speed = 0.35f;
        //吃豆人下一次移动将要去的目的地
        private Vector2 dest = Vector2.zero;
    
        private Animator anim;
    
        private void Awake()
        {
            anim = GetComponent<Animator>();
        }
    
        private void Start()
        {
            //保证吃豆人在游戏刚开始的时候不会动
            dest = transform.position;
        }
    
        private void FixedUpdate()
        {
            //插值得到要移动到dest位置下一次要移动的坐标
            Vector2 temp = Vector2.MoveTowards(transform.position, dest, speed);
            //通过刚体来设置物体的位置
            GetComponent<Rigidbody2D>().MovePosition(temp);
            //必须先达到上一个dest的位置才可以发出新的目的地的设置指令
            if ((Vector2)transform.position == dest)
            {
                if ((Input.GetKey(KeyCode.UpArrow) || Input.GetKey(KeyCode.W)) && Valid(Vector2.up))
                {
                    anim.SetFloat("DirX", 0);
                    anim.SetFloat("DirY", 1);
                    dest = (Vector2)transform.position + Vector2.up;
                }
                if ((Input.GetKey(KeyCode.DownArrow) || Input.GetKey(KeyCode.S)) && Valid(Vector2.down))
                {
                    anim.SetFloat("DirX", 0);
                    anim.SetFloat("DirY", -1);
                    dest = (Vector2)transform.position + Vector2.down;
                }
                if ((Input.GetKey(KeyCode.LeftArrow) || Input.GetKey(KeyCode.A)) && Valid(Vector2.left))
                {
                    anim.SetFloat("DirX", -1);
                    anim.SetFloat("DirY", 0);
                    dest = (Vector2)transform.position + Vector2.left;
                }
                if ((Input.GetKey(KeyCode.RightArrow) || Input.GetKey(KeyCode.D)) && Valid(Vector2.right))
                {
                    anim.SetFloat("DirX", 1);
                    anim.SetFloat("DirY", 0);
                    dest = (Vector2)transform.position + Vector2.right;
                }
            }
        }
    
        private bool Valid(Vector2 dir)
        {
            Vector2 pos = transform.position;
            RaycastHit2D hit = Physics2D.Linecast(pos + dir, pos);
            return (hit.collider == GetComponent<Collider2D>());
        }
    }

运行程序结果如下
