unity3D2D简单的怪物自动寻路

适合2D游戏怪物自动寻路,不会攻击人

①首先创建怪物到面板,并添加左右移动坐标点

所谓的左右点就是创建两个空对象,拖到需要移动的位置,当怪物的子物体

②创建脚本拖到怪物上,将左右移动坐标点物体拖入对应位置

效果

代码部分

1 using System.Collections;
2 using System.Collections.Generic;
3 using UnityEngine;
4
5 public class monster_frog : MonoBehaviour
6 {
7 public Rigidbody2D rb; //怪物刚体
8 public Transform pos_left, pos_right; //怪物移动左右坐标
9 public float speed; //移动速速
10 public bool faceLeft = true; //脸朝向
11 public float leftx, rightx; //存储怪物移动左右坐标点
12
13 // Start is called before the first frame update
14 void Start()
15 {
16 rb = GetComponent();
17 //断绝当前对象的子父级关系,这样做是为了让子物体的坐标不跟随父物体一起移动
18 transform.DetachChildren();
19 //获取坐标
20 leftx = pos_left.position.x;
21 rightx = pos_right.position.x;
22 //卸磨杀驴,节省资源
23 Destroy(pos_left.gameObject);
24 Destroy(pos_right.gameObject);
25 }
26
27 // Update is called once per frame
28 void Update()
29 {
30 move();
31 }
32
33 //移动
34 void move()
35 {
36 //如果脸朝左
37 if (faceLeft)
38 {
39 //就朝左移动,y轴不变
40 rb.velocity = new Vector2(-speed, rb.velocity.y);
41
42 //如果当前坐标小于左侧坐标
43 if (transform.position.x 44 {
45 //掉头 -1是往右看
46 transform.localScale = new Vector3(-1, 1, 1);
47 faceLeft = false;
48 }
49 }
50 //如果脸朝右
51 else
52 {
53 //则向右移动
54 rb.velocity = new Vector2(speed, rb.velocity.y);
55
56 //掉头,往左
57 if (transform.position.x > rightx)
58 {
59 transform.localScale = new Vector3(1, 1, 1);
60 faceLeft = true;
61 }
62 }
63 }
64 }

补充:

怪物需要的组件有:

Rigidbody2D

Circle Collider 2D 圆形碰撞器 目的是不让怪物摔倒

剩下就可以添加对应的动画效果
