unity3d开发巡逻兵游戏
游戏规则:
* 创建一个地图和若干巡逻兵(使用动画)；
* 每个巡逻兵走一个3~5个边的凸多边型，位置数据是相对地址。即每次确定下一个目标位置，用自己当前位置为原点计算；
* 巡逻兵碰撞到障碍物，则会自动选下一个点为目标；
* 巡逻兵在设定范围内感知到玩家，会自动追击玩家；
* 失去玩家目标后，继续巡逻；
程序设计要求：
* 必须使用订阅与发布模式传消息
* 工厂模式生产巡逻兵

代码实现
巡逻兵创建
- 给巡逻兵添加两个预制体, Box Collider和Capsule Collider, BoxCollider使用trigger检测player进入巡逻兵的范围，Capsule Collider用来检测player与巡逻兵的碰撞
- PatrolData：巡逻兵数据
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public enum Dir { down, right, up, left}
public class PatrolData : MonoBehaviour {
// Use this for initialization
//巡逻兵的路线为一个正方形
public Vector3 startPostion; //巡逻的起始位置
public Vector3 endPostion;//正方形对角线位置
public int sideLength; //正方形边长
public int dir = 0;
public GameObject player; //玩家
public int sign; //巡逻兵在哪一块区域
}PatrolFactory创建巡逻兵的工厂
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PatrolFactory : MonoBehaviour {
private List patrols = new List();
// Use this for initialization
public List GetPatrols()
{
int rectLength; //正方形边长
int[] pos_x = { 5, -2, -9 };
int[] pos_z = { 5, -2, -9 };
int index = 1;
for (int i = 0; i < 3; ++i)
{
for (int j = 0; j < 3; ++j)
{
Vector3 startPostion = new Vector3(pos_x[i], 0, pos_z[j]);
rectLength = UnityEngine.Random.Range(3, 5);
Vector3 endPostion = new Vector3(pos_x[i] + rectLength, 0, pos_z[j] + rectLength);
GameObject monster = Instantiate(Resources.Load("Prefabs/Monster"));
monster.transform.position = startPostion;
PatrolData data = monster.AddComponent();
data.startPostion = startPostion;
data.endPostion = endPostion;
data.sideLength = rectLength;
data.sign = index;
patrols.Add(monster);
++index;
}
