Unity3D学习笔记（4）—— 牧师和魔鬼游戏
牧师和魔鬼游戏是一款益智类游戏，游戏的目标是将3个牧师和3个魔鬼从河的一端安全地送到河的另一端。在运送过程中，船可以搭载两个人，而且必须有一人掌船。无论何时，只要河一边的魔鬼数量多于牧师的数量，游戏就会以失败结束。想玩玩的话请走传送门：Priests and Devils
先上个成品草图：
游戏需要的对象：
游戏角色：3个牧师、3个魔鬼
游戏场景：2个河岸、1艘小船
游戏的架构：
UserInterface用来创建GUI对象接受玩家动作，处理GUI事件，使用 IUserActions 接口控制游戏。
SceneController是单实例对象，用来处理对象间通信和实现 IUserActions 接口。
BaseCode用来保存游戏名称和游戏简介，它注册在 SceneController 中。
GenGameObject用来创建游戏对象和处理对象运动，它也注册在 SceneController 中。IUserActions 接口通过与 GenGameObject 互动完成游戏逻辑。
想看完整的代码请直接跳至结尾~
一、新建一个3d游戏项目，建立 BaseCode 脚本，并挂载到主摄像机。
在根目录 Assets 下创建 Scripts 文件夹，在 Scripts 文件夹下创建BaseCode 脚本：
在 BaseCode 脚本里面声明一个新的命名空间 Com.Mygame，并把单实例对象 GameSceneController 定义其中。这样的话，其它脚本要使用 GameSceneController 只需要在脚本开头添加 “using Com.Mygame” 就可以使用对象了，同时命名空间也将我们自己的类和系统类分别开来。BaseCode 脚本的代码如下：
using UnityEngine;
using System.Collections;
using Com.Mygame;
namespace Com.Mygame {
public class GameSceneController: System.Object {
private static GameSceneController _instance;
private BaseCode _base_code;
public static GameSceneController GetInstance() {
if (null == _instance) {
_instance = new GameSceneController();
}
return _instance;
}
public BaseCode getBaseCode() {
return _base_code;
}
internal void setBaseCode(BaseCode bc) {
if (null == _base_code) {
_base_code = bc;
}
}
}
}
public class BaseCode : MonoBehaviour {
public string gameName;
public string gameRule;
void Start () {
GameSceneController my = GameSceneController.GetInstance();
my.setBaseCode(this);
}
}
所谓单例类，即是全局中只能存在唯一一个对象的类，通过函数GetInstance()可以获得这个类的实例对象。因为 GameSceneController 单例类直接声明在 Com.Mygame 命名空间里，因此是全局的，在其中注入的对象都可以看作是全局对象，比如 BaseCode 对象。
这样做的目的是实现代码的MVC架构，通过在单例类中注入对象可以实现对象间的通信，而无需使用 Find、SendMessage 这类破坏程序结构的通讯耦合语句。
我希望用 BaseCode 记录游戏的名字和游戏的简介，因此在 BaseCode 中声明了两个公有变量 gameName、gameRule，它们会被将来的GUI对象获取并显示。
二、新建脚本GenGameObjects，挂载到主摄相机。新建脚本IUserInterface，挂载到一个Empty对象。
三、在 GenGameObjects 中创建长方形、正方形、球及其色彩代表游戏中的对象。并把组件自己注入到 GameSceneController 单例模式对象。
先在游戏面板创建游戏对象，在 Assets 文件夹下新建 Resources 文件夹，在 Resources 文件夹下新建 Prefabs 文件夹，然后将创建的对象拖入 Prefabs 中成为预设物体。
我假设牧师为球体、魔鬼为正方体、河岸为长方体、船也为长方体：
设置主摄像机的投影模式为正交投影，调整大小，这样看到的所有物体都是平面的了。
GenGameObect 部分代码：
public class GenGameObject : MonoBehaviour {
Stack<GameObject> priests_start = new Stack<GameObject>();
Stack<GameObject> priests_end = new Stack<GameObject>();
Stack<GameObject> devils_start = new Stack<GameObject>();
Stack<GameObject> devils_end = new Stack<GameObject>();
GameObject[] boat = new GameObject[2];
GameObject boat_obj;
public float speed = 100f;
GameSceneController my;
Vector3 shoreStartPos = new Vector3(0, 0, -12);
Vector3 shoreEndPos = new Vector3(0, 0, 12);
Vector3 boatStartPos = new Vector3(0, 0, -4);
Vector3 boatEndPos = new Vector3(0, 0, 4);
float gap = 1.5f;
Vector3 priestStartPos = new Vector3(0, 2.7f, -11f);
Vector3 priestEndPos = new Vector3(0, 2.7f, 8f);
Vector3 devilStartPos = new Vector3(0, 2.7f, -16f);
Vector3 devilEndPos = new Vector3(0, 2.7f, 13f);
这部分声明了 GenGameObject 各变量，其中我打算用 Stack 集合类型存储牧师和魔鬼对象，start表示开始岸，end表示目标岸。
船需要三个变量，boat是一个对象数组，用来存储船所承载的物体，boat_obj为船的实体。Speed为公有变量（方便更改），代表船行驶的速度。
My是一个 GameSceneController 对象，之所以需要 GameSceneController，是因为游戏逻辑需要“状态”，这些“状态”为枚举类型，并且保存在 GameSceneController 中。
剩下的一系列 Vector3 类型，均表示物理位置，它们会在牧师、魔鬼、河岸、船预设实例化的时候被使用，或者在游戏物体需要移动时使用。
void Start () {
my = GameSceneController.GetInstance();
my.setGenGameObject(this);
loadSrc();
}
这部分代码将 GenGameObject 对象注入了 GameSceneController 单实例对象中。当然，要在GameSceneController中定义该函数：
public GenGameObject getGenGameObject() {
return _gen_game_obj;
}
internal void setGenGameObject(GenGameObject ggo) {
if (null == _gen_game_obj) {
_gen_game_obj = ggo;
}
}
loadSrc()用来实例化游戏对象：
void loadSrc() {
// shore
Instantiate(Resources.Load("Prefabs/Shore"), shoreStartPos, Quaternion.identity);
Instantiate(Resources.Load("Prefabs/Shore"), shoreEndPos, Quaternion.identity);
// boat
boat_obj = Instantiate(Resources.Load("Prefabs/Boat"), boatStartPos, Quaternion.identity) as GameObject;
// priests & devils
for (int i = 0; i < 3; ++i) {
priests_start.Push(Instantiate(Resources.Load("Prefabs/Priest")) as GameObject);
devils_start.Push(Instantiate(Resources.Load("Prefabs/Devil")) as GameObject);
}
// light
Instantiate(Resources.Load("Prefabs/Light"));
}
其中 light 是后来添加上去的，为了让场景中有光亮。注意，只有在 Resources 文件夹下的资源才能使用 Load 加载。
四、用表格列出玩家动作表（规则表）
在继续编写 GenGameObject 脚本之前，我们要明确游戏允许玩家的所有动作。这里，我规定的玩家动作有7个：
| 项目 | 条件 |
| 开船 | 船在开始岸、船在结束岸 |
| 船的左方下船 | 船靠岸且船左方有人 |
| 船的右方下船 | 船靠岸且船右方有人 |
| 开始岸的牧师上船 | 船在开始岸，船有空位，开始岸有牧师 |
| 开始岸的魔鬼上船 | 船在开始岸，船有空位，开始岸有魔鬼 |
| 结束岸的牧师上船 | 船在结束岸，船有空位，结束岸有牧师 |
| 结束岸的魔鬼上船 | 船在结束岸，船有空位，结束岸有魔鬼 |
五、基于规则表完善 GenGameObject 类
考虑到牧师和魔鬼的位置时刻要根据堆栈的数据变化，因此先定义一个 setCharacterPositions 函数。该函数接受一个stack参数，和一个Vector3坐标。它的作用就是把stack里的object从Vector3坐标开始依次排开：
void setCharacterPositions(Stack<GameObject> stack, Vector3 pos) {
GameObject[] array = stack.ToArray();
for (int i = 0; i < stack.Count; ++i) {
array[i].transform.position = new Vector3(pos.x, pos.y, pos.z + gap*i);
}
}
然后在 Update 方法里便可以使用：
void Update() {
setCharacterPositions(priests_start, priestStartPos);
setCharacterPositions(priests_end, priestEndPos);
setCharacterPositions(devils_start, devilStartPos);
setCharacterPositions(devils_end, devilEndPos);
现在，我们来考虑规则抽象的行为，分为3种： 上船、 开船、 下船。
1． 上船：把一个游戏对象设为船的子对象。
定义 getOnTheBoat 函数，接受一个游戏对象为参数，只要船上有空位，就把游戏对象设置为船的子对象，这样游戏对象便能跟着船移动：
void getOnTheBoat(GameObject obj) {
if (boatCapacity() != 0) {
obj.transform.parent = boat_obj.transform;
if (boat[0] == null) {
boat[0] = obj;
obj.transform.localPosition = new Vector3(0, 1.2f, -0.3f);
} else {
boat[1] = obj;
obj.transform.localPosition = new Vector3(0, 1.2f, 0.3f);
}
}
}
2． 开船：根据游戏“状态”，把船从一方移动到另一方。
这里，我们讨论到了游戏状态，我们需要游戏状态了解船当前的位置。游戏状态作为枚举类型声明在 BaseCode 脚本中：
public enum State { BSTART, BSEMOVING, BESMOVING, BEND, WIN, LOSE };
/*
* BSTART: boat stops on start shore
* BEND: boat stops on end shore
* BSEMOVING: boat is moving from start shore to end shore
* BESMOVING: boat is moving from end shore to start shore
* WIN: win
* LOSE: lose
*/
有了游戏状态，只需要定义一个 moveBoat 函数，修改游戏状态为MOVING即可，剩下的动作均在Update函数中完成：
public void moveBoat() {
if (boatCapacity() != 2) {
if (my.state == State.BSTART) {
my.state = State.BSEMOVING;
}
else if (my.state == State.BEND) {
my.state = State.BESMOVING;
}
}
}
3． 下船：取消船和游戏对象的父子关系，并且根据游戏“状态”将游戏对象压入stack。
定义 getOffTheBoat 函数，接受一个整型变量为参数，该变量可以为0或1：
public void getOffTheBoat(int side) {
if (boat[side] != null) {
boat[side].transform.parent = null;
if (my.state == State.BEND) {
if (boat[side].tag == "Priest") {
priests_end.Push(boat[side]);
}
else if (boat[side].tag == "Devil") {
devils_end.Push(boat[side]);
}
}
else if (my.state == State.BSTART) {
if (boat[side].tag == "Priest") {
priests_start.Push(boat[side]);
}
else if (boat[side].tag == "Devil") {
devils_start.Push(boat[side]);
}
}
boat[side] = null;
}
}
注意到，为了区分出牧师和魔鬼，我给牧师和魔鬼预设分别添加了 Tag。Tag需要在控制面板添加。
除此以外，还需要判断游戏的输赢，定义一个 check 函数：
void check() {
int pOnb = 0, dOnb = 0;
int priests_s = 0, devils_s = 0, priests_e = 0, devils_e = 0;
if (priests_end.Count == 3 && devils_end.Count == 3) {
my.state = State.WIN;
return;
}
for (int i = 0; i < 2; ++i) {
if (boat[i] != null && boat[i].tag == "Priest") pOnb++;
else if (boat[i] != null && boat[i].tag == "Devil") dOnb++;
}
if (my.state == State.BSTART) {
priests_s = priests_start.Count + pOnb;
devils_s = devils_start.Count + dOnb;
priests_e = priests_end.Count;
devils_e = devils_end.Count;
}
else if (my.state == State.BEND) {
priests_s = priests_start.Count;
devils_s = devils_start.Count;
priests_e = priests_end.Count + pOnb;
devils_e = devils_end.Count + dOnb;
}
if ((priests_s != 0 && priests_s < devils_s) || (priests_e != 0 && priests_e < devils_e)) {
my.state = State.LOSE;
}
}
修改 Update 函数，加入船的移动，游戏结束条件的判断：
void Update() {
setCharacterPositions(priests_start, priestStartPos);
setCharacterPositions(priests_end, priestEndPos);
setCharacterPositions(devils_start, devilStartPos);
setCharacterPositions(devils_end, devilEndPos);
if (my.state == State.BSEMOVING) {
boat_obj.transform.position = Vector3.MoveTowards(boat_obj.transform.position, boatEndPos, speed*Time.deltaTime);
if (boat_obj.transform.position == boatEndPos) {
my.state = State.BEND;
}
}
else if (my.state == State.BESMOVING) {
boat_obj.transform.position = Vector3.MoveTowards(boat_obj.transform.position, boatStartPos, speed*Time.deltaTime);
if (boat_obj.transform.position == boatStartPos) {
my.state = State.BSTART;
}
}
else check();
}
OK，游戏的基本动作已经全部实现了！
不过，为了与玩家规则表对应，还需要定义4个函数：
priestStartOnBoat、priestEndOnBoat、devilStartOnBoat、devilEndOnBoat
它们的作用是调用相应的 getOnTheBoat 函数，把玩家指定的对象放到船上：
public void priestStartOnBoat() {
if (priests_start.Count != 0 && boatCapacity() != 0 && my.state == State.BSTART)
getOnTheBoat(priests_start.Pop());
}
public void priestEndOnBoat() {
if (priests_end.Count != 0 && boatCapacity() != 0 && my.state == State.BEND)
getOnTheBoat(priests_end.Pop());
}
public void devilStartOnBoat() {
if (devils_start.Count != 0 && boatCapacity() != 0 && my.state == State.BSTART)
getOnTheBoat(devils_start.Pop());
}
public void devilEndOnBoat() {
if (devils_end.Count != 0 && boatCapacity() != 0 && my.state == State.BEND)
getOnTheBoat(devils_end.Pop());
}
六、修改 BaseCode 脚本，添加 IUserActions 接口，并在 GameSceneController 中实现。
回到 BaseCode 脚本，在命名空间 Com.Mygame 里添加 IUserActions 接口：
public interface IUserActions {
void priestSOnB();
void priestEOnB();
void devilSOnB();
void devilEOnB();
void moveBoat();
void offBoatL();
void offBoatR();
void restart();
}
在 GameSceneController 中添加接口的实现方法：
public void priestSOnB() {
_gen_game_obj.priestStartOnBoat();
}
public void priestEOnB() {
_gen_game_obj.priestEndOnBoat();
}
public void devilSOnB() {
_gen_game_obj.devilStartOnBoat();
}
public void devilEOnB() {
_gen_game_obj.devilEndOnBoat();
}
public void moveBoat() {
_gen_game_obj.moveBoat();
}
public void offBoatL() {
_gen_game_obj.getOffTheBoat(0);
}
public void offBoatR() {
_gen_game_obj.getOffTheBoat(1);
}
public void restart() {
Application.LoadLevel(Application.loadedLevelName);
state = State.BSTART;
}
注意，多了一个 Restart 方法哦~
七、修改 UserInterface 脚本，创建GUI对象，处理GUI事件。
这里就不多讲了，主要是编写OnGUI函数，在合适的位置添加按钮，并且调用按钮所对应的接口函数：
if (GUI.Button(new Rect(castw(2f), casth(6f), width, height), "Go")) {
action.moveBoat();
}
if (GUI.Button(new Rect(castw(10.5f), casth(4f), width, height), "On")) {
action.devilSOnB();
}
if (GUI.Button(new Rect(castw(4.3f), casth(4f), width, height), "On")) {
action.priestSOnB();
}
if (GUI.Button(new Rect(castw(1.1f), casth(4f), width, height), "On")) {
action.devilEOnB();
}
if (GUI.Button(new Rect(castw(1.3f), casth(4f), width, height), "On")) {
action.priestEOnB();
}
if (GUI.Button(new Rect(castw(2.5f), casth(1.3f), width, height), "Off")) {
action.offBoatL();
}
if (GUI.Button(new Rect(castw(1.7f), casth(1.3f), width, height), "Off")) {
action.offBoatR();
}
当然啦，真正的代码不止这么少，比如要考虑游戏简介的显示（点击左上角会弹出简介框），还要考虑什么时候要隐藏用户操作的按钮（船在行驶的时候和游戏结束的时候）。
到此为止，游戏已经基本完成了！
整个游戏代码中没有出现 Find、SendMessage 等破坏程序结构的通讯耦合语句，场景中除了主摄像机和一个 Empty 对象外，所有其他的游戏对象都由代码动态生成。
事实上，你可以把场景弄得更好看些：
