结果演示
智能巡逻兵
1. 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；
2. 程序设计要求
- 必须使用订阅与发布模式传消息
- subject：OnLostGoal
- Publisher: ?
- Subscriber: ?
- 工厂模式生产巡逻兵
实现过程
制作预制
制作主角Hero、巡逻兵Patrol、地图SceneMode的预制如下图
主要代码实现如下
-
GameModel.cs
游戏逻辑主体，实现包括生产英雄、巡逻兵、移动、追捕等。在师兄博客的基础上做了改进，实现了hero碰撞栅栏和边界的检测，只能从栅栏之间的空隙穿过（原实现hero可任意穿过栅栏并在走出边界后会掉落）

SSActionManager.cs
用动作队列实现巡逻兵正常和追捕这两个动作的流畅切换和管理，包括碰撞的检测，正常巡逻时的转向等
using UnityEngine; using System.Collections; using System.Collections.Generic; //并发顺序 public class SSActionManager : MonoBehaviour { private Dictionary<int, SSAction> actions = new Dictionary<int, SSAction>(); private List<SSAction> waitingAdd = new List<SSAction>(); private List<int> waitingDelete = new List<int>(); protected void Start () { } protected void Update() { foreach (SSAction ac in waitingAdd) { actions[ac.GetInstanceID()] = ac; } waitingAdd.Clear(); foreach (KeyValuePair<int, SSAction> kv in actions) { SSAction ac = kv.Value; if (ac.destroy) { waitingDelete.Add(kv.Key); } else if (ac.enable) { ac.Update(); } } foreach (int key in waitingDelete) { SSAction ac = actions[key]; actions.Remove(key); Object.Destroy(ac); } waitingDelete.Clear(); } public void runAction(GameObject gameObj, SSAction action, ISSActionCallback manager) { // 先把该对象现有的动作销毁（与原来不同的动作类型） for (int i = 0; i < waitingAdd.Count; i++) { if (waitingAdd[i].gameObject.Equals(gameObj)) { SSAction ac = waitingAdd[i]; waitingAdd.RemoveAt(i); i--; Object.Destroy(ac); } } foreach (KeyValuePair<int, SSAction> kv in actions) { SSAction ac = kv.Value; if (ac.gameObject.Equals(gameObj)) { ac.destroy = true; } } action.gameObject = gameObj; action.transform = gameObj.transform; action.callBack = manager; waitingAdd.Add(action); action.Start(); } } -
PatrolBehaviour.cs
挂载到每个巡逻兵，实现巡逻兵对hero的感知和追踪，以及正常和追捕状态的转换。若处于追捕状态，而发现玩家已不在自己的区域，说明在刚一瞬间，玩家逃离了自己区域，此时会添加随机动作，即继续巡逻。
using System.Collections; using System.Collections.Generic; using UnityEngine; using Com.Patrols; public class PatrolBehaviour : MonoBehaviour { private IAddAction addAction; private IGameStatusOp gameStatusOp; public int ownIndex; // 判断是否在追捕状态 public bool isCatching; void Start () { addAction = SceneController.getInstance() as IAddAction; gameStatusOp = SceneController.getInstance() as IGameStatusOp; ownIndex = getOwnIndex(); isCatching = false; } void Update () { checkNearByHero(); } int getOwnIndex() { string name = this.gameObject.name; char cindex = name[name.Length - 1]; int result = cindex - '0'; return result; } // 检测所在区域有无hero void checkNearByHero () { // hero在自己区域 if (gameStatusOp.getHeroStandOnArea() == ownIndex) { if (!isCatching) { isCatching = true; addAction.addDirectMovement(this.gameObject); } } else { if (isCatching) { gameStatusOp.heroEscapeAndScore(); isCatching = false; addAction.addRandomMovement(this.gameObject, false); } } } void OnCollisionStay(Collision e) { // 碰到围栏，选择下一个点移动 if (e.gameObject.name.Contains("Patrol") || e.gameObject.name.Contains("fence") || e.gameObject.tag.Contains("FenceAround")) { isCatching = false; addAction.addRandomMovement(this.gameObject, false); } // 碰到hero，游戏结束 if (e.gameObject.name.Contains("Hero")) { gameStatusOp.patrolHitHeroAndGameover(); Debug.Log("Game Over!"); } } } -
GameEventManager.cs
采用订阅和发布模式，传递得分、游戏结束等消息，当玩家得分或游戏结束时，都会GameEventManager的得分/游戏结束方法
using System.Collections; using System.Collections.Generic; using UnityEngine; using Com.Patrols; public class GameEventManager : MonoBehaviour { public delegate void GameScoreAction(); public static event GameScoreAction myGameScoreAction; public delegate void GameOverAction(); public static event GameOverAction myGameOverAction; private SceneController scene; void Start () { scene = SceneController.getInstance(); scene.setGameEventManager(this); } void Update () { } // hero逃离巡逻兵追捕，得分+1 public void heroEscapeAndScore() { if (myGameScoreAction != null) { myGameScoreAction(); } } // hero被巡逻兵捕获，游戏结束 public void patrolHitHeroAndGameover() { if (myGameOverAction != null) { myGameOverAction(); } } } -
GameStatusText.cs
传递消息的辅助函数
using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; public class GameStatusText : MonoBehaviour { private int score = 0; // 0为score，1为gameover private int textType; void Start () { distinguishText(); } void Update () { } void distinguishText() { if (gameObject.name.Contains("Score")) textType = 0; else textType = 1; } void OnEnable() { GameEventManager.myGameScoreAction += gameScore; GameEventManager.myGameOverAction += gameOver; } void OnDisable() { GameEventManager.myGameScoreAction -= gameScore; GameEventManager.myGameOverAction -= gameOver; } void gameScore() { if (textType == 0) { score++; this.gameObject.GetComponent<Text>().text = "Score: " + score; } } void gameOver() { if (textType == 1) this.gameObject.GetComponent<Text>().text = "Game Over!"; } }
