IF 语句完成后 Java 重新触发循环

Question

我正在尝试制作一个简单的基于文本的冒险作为初学者java的练习，但是我遇到了一个问题，经过很长时间的搜索我决定只是问它。 我想知道如何在 IF 语句得到答复后重新触发此循环，例如。用户输入:“帮助”，帮助选项卡显示，用户可以输入另一个命令。 我不知道为什么这不起作用，所以任何帮助将不胜感激。

boolean loopone = false;
    do {
    System.out.println(name + " is standing in a forest, covered in slime goo.");
    String cmdone = in.next();
    if (cmdone.equals("Help")) {
        System.out.println("---------Help---------");
        System.out.println("Type: [Help] to view help");
        System.out.println("Type: [Turn] to turn, syntax: [Turn (direction)] left, right and backward are the possible directions");
        System.out.println("Type: [Enter] to go through an entrance");
        System.out.println("Type: [Slay] to kill stuff");
        System.out.println("Type: [Take] to take stuff");
        System.out.println("Typing: [/rocket smallbrains] has no effect here");
        return;
        }
        else if (cmdone.equals("Enter")){
            System.out.println("Enter what?");  
            String conone = in.next();
            if (conone.equals("Forest")  || conone.equals("The forest")){
                System.out.println("You're already in the forest, dummy!");
            }
            else{
                System.out.println("I don't know where that is");
            }

        }
        else if (cmdone.equals("Turn right")){
            System.out.println("You turn right");
        }
    continue;
    }while (loopone = false);

Answer 1

一个问题是你需要这样做:

}while (loopone = false);

这个:

}while (loopone == false);

否则，您只需确保在每个 if 语句中将 loopone 设置为 false。当您想退出时，请将 loopone 设置为 true (loopone = true)。
