unity3d开发巡逻兵游戏

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

1. 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
2. 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<GameObject> patrols = new List<GameObject>();// Use this for initializationpublic List<GameObject> 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<GameObject>("Prefabs/Monster"));ansform.position = startPostion;PatrolData data =  monster.AddComponent<PatrolData>();data.startPostion = dPostion = endPostion;data.sideLength = rectLength;data.sign = index;patrols.Add(monster);++index;}}return patrols;}
}

巡逻兵追捕与巡逻动作
PatrolGoAction

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PatrolGoAction : SSAction {private Vector3 start; //巡逻兵的起始位置private Vector3 end;//巡逻兵起始位置的正方形对角线位置private Vector3 next;private int dir; //方向:0 x+, 1：z+, 2:x-,3:z-// Use this for initializationpublic static SSAction getPatrolGoAction(){PatrolGoAction action = ScriptableObject.CreateInstance<PatrolGoAction>();return action;}public override void Start () {PatrolData data = gameObject.GetComponent<PatrolData>();dir = 0;start = data.startPostion;end = dPostion;// transform.localEulerAngles =new  Vector3(0, 90, 0);next = new Vector3(end.x,0,start.z);transform.LookAt(next);able = true;this.distroy = false;}// Update is called once per framepublic override void Update () {//防止碰撞发生后的旋转if (transform.localEulerAngles.x != 0 || transform.localEulerAngles.z != 0){transform.localEulerAngles = new Vector3(0, transform.localEulerAngles.y, 0);}if (transform.position.y != 0){transform.position = new Vector3(transform.position.x, 0, transform.position.z);}//移动transform.position = Vector3.MoveTowards(transform.position, next, Time.deltaTime * 2f);gameObject.GetComponent<Animator>().SetBool("walk", true);GameObject player = gameObject.GetComponent<PatrolData>().player;if (player !=null && player.GetComponent<PlayerData>().area == gameObject.GetComponent<PatrolData>().sign ){this.callback.SSActionEvent(this, 0, this.gameObject);}if (Vector3.Distance(transform.position, next) < 0.1){dir = (dir + 1) % 4;if (dir == 1){next = new Vector3(end.x, 0, end.z);}else if (dir == 2){next = new Vector3(start.x, 0, end.z);}else if (dir == 3){next = new Vector3(start.x, 0, start.z);}else{next = new Vector3(end.x, 0, start.z);}transform.LookAt(next);}}
}

PatrolFollowAction

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PatrolFollowAction : SSAction {public GameObject player;// Use this for initializationpublic override void Start () {this.distroy = able = true;}// Update is called once per framepublic override void Update () {//防止碰撞发生后的旋转if (transform.localEulerAngles.x != 0 || transform.localEulerAngles.z != 0){transform.localEulerAngles = new Vector3(0, transform.localEulerAngles.y, 0);}if (transform.position.y != 0){transform.position = new Vector3(transform.position.x, 0, transform.position.z);}transform.ansform.position);transform.position = Vector3.MoveTowards(transform.position, ansform.position, Time.deltaTime * 1.5f);gameObject.GetComponent<Animator>().SetBool("walk", true);player = gameObject.GetComponent<PatrolData>().player;if(player == null || player.GetComponent<PlayerData>().area != gameObject.GetComponent<PatrolData>().sign){this.callback.SSActionEvent(this, 1, this.gameObject);}}public static SSAction GetPatrolFollowAction(GameObject player){PatrolFollowAction action = ScriptableObject.CreateInstance<PatrolFollowAction>();action.player = player;return action;}
}

玩家数据

PlayerData

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerData : MonoBehaviour {public int area = 1; //玩家位于地图那一块区域
}

SSActionManager与PatrolActionManager

SSActionManager

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class SSActionManager : MonoBehaviour,ISSActionCallback {protected Dictionary<int, SSAction> actions = new Dictionary<int, SSAction>();protected List<SSAction> waitingAdd = new List<SSAction>();protected List<int> waitingDelete = new List<int>();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.distroy){waitingDelete.Add(ac.GetInstanceID());}else if (ac.enable){ac.Update();}}foreach (int key in waitingDelete){SSAction ac = actions[key];actions.Remove(key);DestroyObject(ac);}waitingDelete.Clear();}public void DestroyAllAction(){foreach (KeyValuePair<int, SSAction> kv in actions){SSAction ac = kv.Value;ac.gameObject.GetComponent<Animator>().SetBool("walk", false);ac.distroy = true;}}public void RunAction(GameObject gameobject, SSAction action, ISSActionCallback manager){action.gameObject = ansform = ansform;action.callback = manager;waitingAdd.Add(action);action.Start();}protected void Start(){}public void SSActionEvent(SSAction source, int intParam = 0, GameObject objectParam = null){if (intParam == 0){//跟踪玩家source.distroy = true;GameObject player = objectParam.GetComponent<PatrolData>().player;SSAction follow= PatrolFollowAction.GetPatrolFollowAction(player);this.RunAction(objectParam,follow, this);}else if(intParam == 1) {//继续巡逻source.distroy = true;objectParam.GetComponent<PatrolData>().player = null;SSAction go = PatrolGoAction();this.RunAction(objectParam, go, this);}}
}

PatrolActionManager

using UnityEngine;public class EventPublisher : MonoBehaviour {//分数实践public delegate void ScoreEvent();public static event ScoreEvent ScoreAddEvent;public delegate void GameEvent();public static event GameEvent GameOverEvent;// Use this for initializationpublic void ScoreAdd(){if(ScoreAddEvent!=null){ScoreAddEvent();}}public void GameOver(){if(GameOverEvent!=null){GameOverEvent();}}
}
