#感覺這門課作業不提前寫真搞不定啊_(:зゝ∠)_
#文末有全部代碼以及操作方法
先把游戲效果po一下吧（白色膠囊體代表牧師、紅色膠囊體代表魔鬼、藍色代表船、兩條白色圓柱體代表兩岸）：
這次作業與TA的實現方法稍有不同，多用了兩個類：PersonStatus（動態加載到6個牧師和惡魔上）用來管理角色上船（即下岸）以及上岸（即下船）的行為；BoatBehaviour（動態加載到船上）用來管理船的移動行為。同時增加了一個IGameJudge接口，用于判斷勝利/失敗行為。其他的應該大致相同，UML圖大概像下面的（第一次畫UML圖， 不知道有沒有錯……）：
【作業要求】：
1、BaseCode 腳本：
此腳本主要作用的在同一個命名空間內定義單例類、定義接口。
由于需要使用單例模式，所以先聲明一個命名空間Com.MyGame。然后在里面定義單例類mainSceneController。由于僅定義了一個單例類，所以并不需要掛載到Main Camera上。
2、GenGameObjects 腳本：
此腳本主要作用是創建所有的游戲對象GameObject，同時實現一些游戲操作邏輯。
(1) 這個腳本需要掛載到Main Camera上。
(2) 在此腳本需要先創建牧師、惡魔、船、兩岸這些GameObject（用幾何體代替）。創建后還需要給游戲對象加上名字（有些需要 加上tag用于后面辨識），設置大小、旋轉角度、顏色、位置等屬性；對于牧師、惡魔、船這幾種游戲對象，還要分別綁定上面提到的PersonStatus、BoatBehaviour腳本。（下面僅放其中一種游戲對象的創建代碼）：
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？？
這是我在BaseCode 腳本里面的Com.MyGame命名空間內先把所有人和物的位置（上岸、下船等一系列位置）先確定，然后在其他的腳本就可以調用靜態變量獲得位置的值了，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與GenGameObjects 的交互：把GenGameObjects 注入到mainSceneController單例模式作為子對象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; } }}同時在GenGameObjects 腳本Start()函數里：mainSceneController.getInstance().setGenGameObjects(this);4、接下來是玩家操作，少的可以分5種：船的移動、牧師上船、牧師上岸、惡魔上船、惡魔上岸；多的可以分7種，即兩種人物上岸可以上左岸或右岸。我這里只讓玩家做5種操作（上左/右岸會按照船的?？课恢脕泶_定，可以自動識別）。(1) 在BaseCode 腳本添加IUserActions接口：
public interface IUserActions { void boatMove(); void priestsGetOn(); void priestsGetOff(); void devilsGetOn(); void devilsGetOff();}(2) 然后在mainSceneController實現IUserActions接口：由于mainSceneController有GenGameObjects子對象，且所有GameObject都在GenGameObjects腳本里創建，所以我在GenGameObjects里真正實現IUserActions接口的五個方法，而在mainSceneController僅通過GenGameObjects子對象調用自身的方法即可：
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; } } /** * 實現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個函數的具體邏輯實現在這里就不放出來了，因為挺繁瑣的_(:зゝ∠)_。5、UserInterface腳本：
此腳本的主要作用是：監聽玩家的操作，并調用IUserActions接口的方法。
我是用MonoBehaviour提供的OnGUI()方法設置了5個按鈕Button分別監聽。代碼就不在這放了，詳見文末完整代碼。
然后創建一個Empty對象，并掛載上去。
6、使用 C# 集合類型組織對象，我是使用List<GameObject>，感覺這個挺好用的。mainSceneController 對象與GenGameObjects 互動完成游戲邏輯上面也提到了。下面提一下新添的兩個類一個新添的接口吧：
(1) PersonStatus類：
這個類動態綁定到每個牧師和惡魔上。主要作用是定義控制自身行為，即上船/上岸兩個方法，并提供給GenGameObjects 在合適情況下調用。同時，PersonStatus類有 位置 和 在船上/岸上 等狀態的成員變量，實現了每個牧師/惡魔自己管理自己（上船/上岸 自身的位置交換），而不需要在一個類里面統一管理，更加方便而且直觀。
(2) BoatBehaviour類：
這個類動態綁定到船上。主要作用是控制船的自身移動，而不需要在其他類里面管理（由于船的移動是通過Update()方法一點點的修
改位置來變化）。此類會提供方法給GenGameObjects 在合適情況下調用，使船移動，同時檢測是否靠岸。
(3) IGameJudge接口：
此接口通過mainSceneController實現。mainSceneController 內會先聲明一些變量來提示岸上/船上的牧師/惡魔的數量，
IGameJudge接口同樣有改變那幾個變量的函數（牧師/惡魔上船/上岸的時候PersonStatus類會調用接口的方法），同時有一個檢測
游戲是否勝利/失敗的函數（船靠岸的時候BoatBehaviour類會調用接口的方法）。
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、船未靠岸通過一個bool變量isMoving來控制玩家不能夠操作。
8、游戲勝利、結束的提示文字需要先把GUI文字做出prefab，然后游戲結束的時候動態生成
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;}項目的組織結構：
9、整個游戲沒有出現 Find 游戲對象， SendMessage 這類突破程序結構的通訊耦合語句。

2、在下面的點擊Create -> Create Empty
3、把GenGameObjects.cs掛載到主攝像機，UserInterface.cs 掛載到Empty對象上。掛載方法：點擊Add Component，輸入腳本名字，點擊腳本，變成右邊的樣子即可
4、按下圖構造好項目結構（所有腳本均放在Scripts文件夾里）。
5、藍色那些是Prefab，構造方法：學第2點，Create -> UI -> Text。然后把Canvas拖到下面的Prefab文件夾。
GameText要設置一下，再拖到Prefab文件夾：
這樣應該是完成了。如果出問題再按照提示改一下唄~
