我遇到了麻煩

Question

我剛剛瞭解瞭如何在java中使用不同的類，但我並不清楚如何去做。我也想知道如何在我的代碼中創建一個足夠的機制來開始和停止我的遊戲。比如當某人輸入了你不應該的東西時，所以它會允許他們再次輸入。請記住，我還沒有完成這個小遊戲。

Answer 1

你在這裏有什麼基本上是state machine。你打印一些東西，然後提出一些選擇;用戶輸入這些選擇中的一個，然後移動到某個不同的「狀態」（即不同的地方），在那裏打印某些內容，顯示選項，移動到新的狀態......等。

您可以代表一個國家是這樣的：

class State { 
    String message; 
    Map<String, State> choices = new LinkedHashMap<>(); 
} 

（左故意裸露，爲清楚起見）

，建設一些這樣的狀態：

State start = new State(); 
start.message = "You find yourself in a car..."; 

State leaveTheCar = new State(); 
leaveTheCar.message = "You get outside of the car..."; 

State openGlovebox = new State(); 
openGlovebox.message = "You find a note..."; 

State dead = new State(); 
dead.message = "You're dead."; 

，並加入美國toget她這個樣子：

start.choices.put("Leave", leaveTheCar); 
start.choices.put("Open glovebox", openGlovebox); 

leaveTheCar.choices.put("Get back in car", start); 
leaveTheCar.choices.put("Blah", dead); 

openGlovebox.choices.put("Bloo", dead); 

所以，你是說，當你在一開始，你可以選擇「離開」，你會移動到「離開車」狀態或「開手套箱「狀態;並且你可以回到車裏，或者做別的事情導致你死亡。

您可以得出這樣一個state transition diagram，其中「節點」的狀態，而「邊緣」是選擇：

你需要創建這些State實例的負荷和加入他們爲您的遊戲上面。但是，一旦你有，「玩」的邏輯很簡單：

State state = start; 
while (true) { 
    System.out.println(state.message); 
    if (state.choices.isEmpty()) { 
    break; // No choices: game over. 
    } 

    while (true) { // Keep going until user enters a valid choice. 
    System.out.println("Choices:"); 
    for (String key : state.choices.keySet()) { 
     System.out.println("'%s'%n", key); 
    } 
    String choice = input.nextLine(); 
    if (state.choices.containsKey(choice)) { 
     state = state.choices.get(choice); // Go to the next state. 
     break; 
    } 

    System.out.println("Choose again!"); 
    } 
} 

爲了實現這一點，檢查出State design pattern相關但略有不同的方式。
