unity3D 2D簡單的怪物自動尋路

適合2D游戲怪物自動尋路,不會攻擊人

①首先創建怪物到面板,並添加左右移動坐標點

所謂的左右點就是創建兩個空對象,拖到需要移動的位置,當怪物的子物體

②創建腳本拖到怪物上,將左右移動坐標點物體拖入對應位置

代碼部分

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class monster_frog : MonoBehaviour
{
    public Rigidbody2D rb;                //怪物剛體
    public Transform pos_left, pos_right; //怪物移動左右坐標
    public float speed;                   //移動速速
    public bool faceLeft = true;          //臉朝向
    public float leftx, rightx;           //存儲怪物移動左右坐標點

    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        //斷絕當前對象的子父級關系,這樣做是為了讓子物體的坐標不跟隨父物體一起移動
        transform.DetachChildren();
        //獲取坐標
        leftx = pos_left.position.x;
        rightx = pos_right.position.x;
        //卸磨殺驢,節省資源
        Destroy(pos_left.gameObject);
        Destroy(pos_right.gameObject);
    }

    // Update is called once per frame
    void Update()
    {
        move();
    }

    //移動
    void move()
    {
        //如果臉朝左
        if (faceLeft)
        {
            //就朝左移動,y軸不變
            rb.velocity = new Vector2(-speed, rb.velocity.y);

            //如果當前坐標小於左側坐標
            if (transform.position.x < leftx)
            {
                //掉頭 -1是往右看
                transform.localScale = new Vector3(-1, 1, 1);
                faceLeft = false;
            }
        }
        //如果臉朝右
        else
        {
            //則向右移動
            rb.velocity = new Vector2(speed, rb.velocity.y);

            //掉頭,往左
            if (transform.position.x > rightx)
            {
                transform.localScale = new Vector3(1, 1, 1);
                faceLeft = true;
            }
        }
    }
}

補充:

怪物需要的組件有:

Rigidbody2D

Circle Collider 2D 圓形碰撞器 目的是不讓怪物摔倒

剩下就可以添加對應的動畫效果
