#感觉这门课作业不提前写真搞不定啊_(:зゝ∠)_
#文末有全部代码以及操作方法
先把游戏效果po一下吧（白色胶囊体代表牧师、红色胶囊体代表魔鬼、蓝色代表船、两条白色圆柱体代表两岸）：
这次作业与TA的实现方法稍有不同，多用了两个类：PersonStatus（动态加载到6个牧师和恶魔上）用来管理角色上船（即下岸）以及上岸（即下船）的行为；BoatBehaviour（动态加载到船上）用来管理船的移动行为。同时增加了一个IGameJudge接口，用于判断胜利/失败行为。其他的应该大致相同，UML图大概像下面的（第一次画UML图， 不知道有没有错……）：
【作业要求】：
1、BaseCode 脚本：
此脚本主要作用的在同一个命名空间内定义单例类、定义接口。
由于需要使用单例模式，所以先声明一个命名空间Com.MyGame。然后在里面定义单例类mainSceneController。由于仅定义了一个单例类，所以并不需要挂载到Main Camera上。
2、GenGameObjects 脚本：
此脚本主要作用是创建所有的游戏对象GameObject，同时实现一些游戏操作逻辑。
(1) 这个脚本需要挂载到Main Camera上。
(2) 在此脚本需要先创建牧师、恶魔、船、两岸这些GameObject（用几何体代替）。创建后还需要给游戏对象加上名字（有些需要 加上tag用于后面辨识），设置大小、旋转角度、颜色、位置等属性；对于牧师、恶魔、船这几种游戏对象，还要分别绑定上面提到的PersonStatus、BoatBehaviour脚本。（下面仅放其中一种游戏对象的创建代码）：
PRiests = new List<GameObject>();for (int i = 0; i < 3; i++) { GameObject priests = GameObject.CreatePrimitive(PrimitiveType.Capsule); priests.name = "Priest " + (i + 1); priests.tag = "Priest"; priests.GetComponent<MeshRenderer>().material.color = Color.white; priests.AddComponent<PersonStatus>(); Priests.Add(priests);}Priests[0].transform.position = LOCATION_SET.priests_1_LOC;Priests[1].transform.position = LOCATION_SET.priests_2_LOC;Priests[2].transform.position = LOCATION_SET.priests_3_LOC;值得注意的是 LOCATION_SET.priests_1_LOC 是什么？？
这是我在BaseCode 脚本里面的Com.MyGame命名空间内先把所有人和物的位置（上岸、下船等一系列位置）先确定，然后在其他的脚本就可以调用静态变量获得位置的值了，像下面的：
public class LOCATION_SET { public static Vector3 priests_1_LOC = new Vector3(5, 3, 0); public static Vector3 priests_2_LOC = new Vector3(6.3f, 3, 0); public static Vector3 priests_3_LOC = new Vector3(7.6f, 3, 0); public static Vector3 devils_1_LOC = new Vector3(9.5f, 3, 0); public static Vector3 devils_2_LOC = new Vector3(10.8f, 3, 0); public static Vector3 devils_3_LOC = new Vector3(12.1f, 3, 0); public static Vector3 boat_left_LOC = new Vector3(-3, 0, 0); public static Vector3 boat_right_LOC = new Vector3(3, 0, 0); public static Vector3 bank_left_LOC = new Vector3(-8.5f, 1.5f, 0); public static Vector3 bank_right_LOC = new Vector3(8.5f, 1.5f, 0); public static Vector3 boatLeft_Pos_1 = new Vector3(-3.7f, 1.5f, 0); public static Vector3 boatLeft_Pos_2 = new Vector3(-2.3f, 1.5f, 0); public static Vector3 boatRight_Pos_1 = new Vector3(2.3f, 1.5f, 0); public static Vector3 boatRight_Pos_2 = new Vector3(3.7f, 1.5f, 0);}3、mainSceneController与GenGameObjects 的交互：把GenGameObjects 注入到mainSceneController单例模式作为子对象public class mainSceneController : System.Object, IUserActions, IGameJudge { private static mainSceneController instance; private GenGameObjects myGenGameObjects; public static mainSceneController getInstance() { if (instance == null) instance = new mainSceneController(); return instance; } internal void setGenGameObjects(GenGameObjects _myGenGameObjects) { if (myGenGameObjects == null) { myGenGameObjects = _myGenGameObjects; } }}同时在GenGameObjects 脚本Start()函数里：mainSceneController.getInstance().setGenGameObjects(this);4、接下来是玩家操作，少的可以分5种：船的移动、牧师上船、牧师上岸、恶魔上船、恶魔上岸；多的可以分7种，即两种人物上岸可以上左岸或右岸。我这里只让玩家做5种操作（上左/右岸会按照船的停靠位置来确定，可以自动识别）。(1) 在BaseCode 脚本添加IUserActions接口：
public interface IUserActions { void boatMove(); void priestsGetOn(); void priestsGetOff(); void devilsGetOn(); void devilsGetOff();}(2) 然后在mainSceneController实现IUserActions接口：由于mainSceneController有GenGameObjects子对象，且所有GameObject都在GenGameObjects脚本里创建，所以我在GenGameObjects里真正实现IUserActions接口的五个方法，而在mainSceneController仅通过GenGameObjects子对象调用自身的方法即可：
public class mainSceneController : System.Object, IUserActions { private static mainSceneController instance; private GenGameObjects myGenGameObjects; public static mainSceneController getInstance() { if (instance == null) instance = new mainSceneController(); return instance; } internal void setGenGameObjects(GenGameObjects _myGenGameObjects) { if (myGenGameObjects == null) { myGenGameObjects = _myGenGameObjects; } } /** * 实现IUserActions接口 **/ public void boatMove() { myGenGameObjects.boatMove(); } public void devilsGetOff() { myGenGameObjects.devilsGetOff(); } public void devilsGetOn() { myGenGameObjects.devilsGetOn(); } public void priestsGetOff() { myGenGameObjects.priestsGetOff(); } public void priestsGetOn() { myGenGameObjects.priestsGetOn(); }}5个函数的具体逻辑实现在这里就不放出来了，因为挺繁琐的_(:зゝ∠)_。5、UserInterface脚本：
此脚本的主要作用是：监听玩家的操作，并调用IUserActions接口的方法。
我是用MonoBehaviour提供的OnGUI()方法设置了5个按钮Button分别监听。代码就不在这放了，详见文末完整代码。
然后创建一个Empty对象，并挂载上去。
6、使用 C# 集合类型组织对象，我是使用List<GameObject>，感觉这个挺好用的。mainSceneController 对象与GenGameObjects 互动完成游戏逻辑上面也提到了。下面提一下新添的两个类一个新添的接口吧：
(1) PersonStatus类：
这个类动态绑定到每个牧师和恶魔上。主要作用是定义控制自身行为，即上船/上岸两个方法，并提供给GenGameObjects 在合适情况下调用。同时，PersonStatus类有 位置 和 在船上/岸上 等状态的成员变量，实现了每个牧师/恶魔自己管理自己（上船/上岸 自身的位置交换），而不需要在一个类里面统一管理，更加方便而且直观。
(2) BoatBehaviour类：
这个类动态绑定到船上。主要作用是控制船的自身移动，而不需要在其他类里面管理（由于船的移动是通过Update()方法一点点的修
改位置来变化）。此类会提供方法给GenGameObjects 在合适情况下调用，使船移动，同时检测是否靠岸。
(3) IGameJudge接口：
此接口通过mainSceneController实现。mainSceneController 内会先声明一些变量来提示岸上/船上的牧师/恶魔的数量，
IGameJudge接口同样有改变那几个变量的函数（牧师/恶魔上船/上岸的时候PersonStatus类会调用接口的方法），同时有一个检测
游戏是否胜利/失败的函数（船靠岸的时候BoatBehaviour类会调用接口的方法）。
public interface IGameJudge { void modifyBoatPriestsNum(bool isAdd); void modifyBoatDevilsNum(bool isAdd); void modifyBankPriestsNum(bool isLeftBank, bool isAdd); void modifyBankDevilsNum(bool isLeftBank, bool isAdd); void judgeTheGame(bool isBoatLeft);}7、船未靠岸通过一个bool变量isMoving来控制玩家不能够操作。
8、游戏胜利、结束的提示文字需要先把GUI文字做出prefab，然后游戏结束的时候动态生成
void showGameText(string textContent) { GameObject Canvas = Camera.Instantiate(Resources.Load("Prefab/Canvas")) as GameObject; GameObject GameText = Camera.Instantiate(Resources.Load("Prefab/GameText"), Canvas.transform) as GameObject; GameText.transform.position = Canvas.transform.position; GameText.GetComponent<Text>().text = textContent;}项目的组织结构：
9、整个游戏没有出现 Find 游戏对象， SendMessage 这类突破程序结构的通讯耦合语句。

2、在下面的点击Create -> Create Empty
3、把GenGameObjects.cs挂载到主摄像机，UserInterface.cs 挂载到Empty对象上。挂载方法：点击Add Component，输入脚本名字，点击脚本，变成右边的样子即可
4、按下图构造好项目结构（所有脚本均放在Scripts文件夹里）。
5、蓝色那些是Prefab，构造方法：学第2点，Create -> UI -> Text。然后把Canvas拖到下面的Prefab文件夹。
GameText要设置一下，再拖到Prefab文件夹：
这样应该是完成了。如果出问题再按照提示改一下呗~
啊好累……_(:зゝ∠)_
