游戏设计要求：
- 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；
- 计分：玩家每次甩掉一个巡逻兵计一分，与巡逻兵碰撞游戏结束;
游戏设计UML图
沿用牧师与魔鬼动作管理器的UML图，适当修改几个类。加上一个工厂和碰撞动作即可。
游戏具体实现
订阅与发布模式
发布订阅(pub/sub)是一种消息通信模式：发送者(pub)发送消息，订阅者(sub)接收消息。
Redis 客户端可以订阅任意数量的频道。
下图展示了频道 channel1 ， 以及订阅这个频道的三个客户端 —— client2 、 client5 和 client1 之间的关系：
当有新消息通过 PUBLISH 命令发送给频道 channel1 时， 这个消息就会被发送给订阅它的三个客户端：
游戏中关键的实现部分
动画部分
自动巡逻兵中因为要用到动画，所以先设置动画控制器，这是player的动画部分
下面是patrol的动画部分
场景部分
脚本部分
触发器设计，作为预制放入资源中
巡逻兵设计，作为预制放入资源中
将下面的脚本挂载到触发器和巡逻兵上，实现玩家碰撞时的通知。
//ColiAction.cs
//该脚本挂载在触发器和巡逻兵上
using UnityEngine;
public class ColiAction : MonoBehaviour {
FirstSceneController sceneController;
GameObject myobject = null;
GameObject player;
public delegate void AddScore();
public static event AddScore myAddScore;
public delegate void GameOver();
public static event GameOver myGameOver;
private void Start()
{
sceneController = SSDirector.getInstance().currentSceneController as FirstSceneController;
player = sceneController.player;
}
private void OnTriggerEnter(Collider other)
{
if (other.gameObject == player)
{
int k = this.name[this.name.Length - 1] - '0';
myobject = sceneController.patrols[k];
foreach (var i in sceneController.actionManager.seq)
{
if (i.gameObject == myobject)
{
i.enable = false;
Vector3 a = new Vector3(myobject.transform.position.x, 0, myobject.transform.position.z);
Vector3 b = new Vector3(player.transform.position.x, 0, player.transform.position.z);
Quaternion rotation = Quaternion.LookRotation(b - a, Vector3.up);
myobject.transform.rotation = rotation;
}
}
}
}
private void OnTriggerExit(Collider other)
{
if (other.gameObject == player)
{
int k = this.name[this.name.Length - 1] - '0';
foreach (var i in sceneController.actionManager.seq)
{
if (i.gameObject == myobject)
{
i.enable = true;
Vector3 a = new Vector3(myobject.transform.position.x, 0, myobject.transform.position.z);
Vector3 b = new Vector3(i.target.x, 0, i.target.z);
Quaternion rotation = Quaternion.LookRotation(b - a, Vector3.up);
myobject.transform.rotation = rotation;
}
}
myobject = null;
myAddScore();
}
}
private void OnCollisionEnter(Collision collision)
{
if(this.tag == "patrol" && collision.gameObject == player)
{
myGameOver();
var k = collision.gameObject.GetComponent<Animator>();
k.SetBool("death",true);
}
}
private void Update()
{
if (myobject != null && sceneController.flag == 0)
{
myobject.transform.position = Vector3.MoveTowards(myobject.transform.position, player.transform.position, 3 * Time.deltaTime);
}
}
}将脚本挂载好之后，我们使用空对象和场景控制器载入场景。为了实现巡逻兵和触发器的一一对应，给触发器名字加上后缀编号，使用列表保存创建好的巡逻兵，这样，一个触发器就能恰好对应到相应的巡逻兵了。
//FirstSceneController.cs
//此脚本挂载到空对象上,在这个脚本里订阅ColiAction

}使用CCActionManager管理每个巡逻兵的巡逻动作和用户的输入
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CCActionManager : SSActionManager, ISSActionCallback {
public FirstSceneController sceneController;
public List<CCMoveToAction> seq = new List<CCMoveToAction>();
public UserAction userAction;
public PatrolFactory pf;
protected new void Start()
{

userAction = UserAction.GetSSAction(5);
sceneController.actionManager = this;
pf = sceneController.pf;
RunAction(sceneController.player, userAction, this);
foreach (var i in sceneController.patrols)
{
float x = Random.Range(-3.0f, 3.0f);
int z = Random.Range(0, 4);
Vector3 target = new Vector3(z % 2 == 0 ? (z - 1) * 3 : x, 0, z % 2 != 0 ? (z - 2) * 3 : x);
CCMoveToAction k = CCMoveToAction.GetSSAction(target+i.transform.position,100,i.transform.position);
seq.Add(k);
Quaternion rotation = Quaternion.LookRotation(target, Vector3.up);
i.transform.rotation = rotation;
RunAction(i, k, this);
}
}
protected new void Update()
{
base.Update();
}
public void SSActionEvent(SSAction source, SSActionEventType events = SSActionEventType.Completed, int intParam = 0, string strParam = null, Object objParam = null)
{
if(source != userAction)
{
CCMoveToAction cCMoveTo = source as CCMoveToAction;
float x = Random.Range(-3.0f, 3.0f);
int z = Random.Range(0, 4);
Vector3 target = new Vector3(z % 2 == 0 ? (z - 1) * 3.0f : x, 0, z % 2 == 0 ? x : (z - 2) * 3.0f);

seq.Remove(cCMoveTo);

seq.Add(k);
Quaternion rotation = Quaternion.LookRotation(target + cCMoveTo.initPosition - source.transform.position, Vector3.up);
source.transform.rotation = rotation;
RunAction(source.gameObject, k, this);
}
}
public void CheckEvent(SSAction source, SSActionEventType events = SSActionEventType.Completed, int intParam = 0, string strParam = null, Object objParam = null)
{
}
public void Pause()
{
if(sceneController.flag == 0)
{
foreach (var k in seq)
{
k.enable = false;
k.gameObject.GetComponent<Animator>().SetBool("running", false);
}
userAction.enable = false;
sceneController.flag = 2;
}
else if(sceneController.flag == 2)
{
foreach (var k in seq)
{
k.enable = true;
k.gameObject.GetComponent<Animator>().SetBool("running", true);
}
userAction.enable = true;
sceneController.flag = 0;
}
}
}巡逻兵工厂和之前的几个博客写的基本相同，大概改改就可以了，详细代码这里略过，想看可以去文末的传送门看看。
用户输入动作脚本用来处理player的移动和动画：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class UserAction : SSAction {
// Use this for initialization
private float speed;
private float rspeed = 90;
public static UserAction GetSSAction(float speed)
{
UserAction action = CreateInstance<UserAction>();
action.speed = speed;
return action;
}
public override void Start()
{
}
public override void Update()
{
if(enable)
{
float translationX = Input.GetAxis("Horizontal");
float translationZ = Input.GetAxis("Vertical");
if (translationX != 0 || translationZ != 0)
{
gameObject.GetComponent<Animator>().SetBool("running", true);
}
else
{
gameObject.GetComponent<Animator>().SetBool("running", false);
}
gameObject.transform.Translate(translationX * speed * Time.deltaTime * 0.1f, 0,translationZ*speed*Time.deltaTime);
gameObject.transform.Rotate(0, translationX * rspeed * Time.deltaTime, 0);
if (gameObject.transform.localEulerAngles.x != 0 || gameObject.transform.localEulerAngles.z != 0)
{
gameObject.transform.localEulerAngles = new Vector3(0, gameObject.transform.localEulerAngles.y, 0);
}
if (gameObject.transform.position.y != 0)
{
gameObject.transform.position = new Vector3(gameObject.transform.position.x, 0, gameObject.transform.position.z);
}
}
}
}其他内容基本和之前的几篇博客相同，在这里就不复述了。
