我遇到了麻烦

Question

我刚刚了解了如何在java中使用不同的类，但我并不清楚如何去做。我也想知道如何在我的代码中创建一个足够的机制来开始和停止我的游戏。比如当某人输入了你不应该的东西时，所以它会允许他们再次输入。请记住，我还没有完成这个小游戏。

package Horror;

Answer 1

你在这里有什么基本上是state machine。你打印一些东西，然后提出一些选择;用户输入这些选择中的一个，然后移动到某个不同的“状态”（即不同的地方），在那里打印某些内容，显示选项，移动到新的状态......等。

您可以代表一个国家是这样的：

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

（左故意裸露，为清楚起见）

，建设一些这样的状态：

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."; 

，并加入美国toget她这个样子：

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，你是说，当你在一开始，你可以选择“离开”，你会移动到“离开车”状态或“开手套箱“状态;并且你可以回到车里，或者做别的事情导致你死亡。

您可以得出这样一个state transition diagram，其中“节点”的状态，而“边缘”是选择：

你需要创建这些State实例的负荷和加入他们为您的游戏上面。但是，一旦你有，“玩”的逻辑很简单：

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!"); 
    } 
} 

为了实现这一点，检查出State design pattern相关但略有不同的方式。
