制作一个简单的基于文本的RPG比预期更难

Sooooo ...我正在使用JAVA构建基于文本的RPG，但有些事情是错误的.... 它会编译，它会运行，但是......好吧，很难解释。我会把代码放在第一位。

    import java.util.Scanner;

public class XOBYT
{

    public static void main(String[] args)
    {
        String choice;
        Scanner scan = new Scanner(System.in);
        System.out.println("COPYRIGHT 2016 HARBNGER STUDIOS\nYou wake up in a broken-down alabaster\nhouse with no knowledge of who\nyou are or where you came from.\nWhich direction do you want to head? (options: NORTH, SOUTH, EAST, WEST)");
        choice = scan.nextLine();{
            if(choice.equals("NORTH")){System.out.println("\n\n\n\n--TERMINAL_LOG--\n\nI FOUND THIS HANDHELD TERMINAL LOG FIGURED I'D\nPUT IT TO SOME USE.

            choice = scan.nextLine();{

                choice = scan.nextLine();{

                if(choice.equals("FARTHER")){
                System.out.println("\n\n\n\n--TERMINAL_LOG--\n\nI FOUND THIS HANDHELD TERMINAL LOG FIGURED I'D\nPUT IT TO SOME USE.

                if(choice.equals("EXPLORE")){

                choice = scan.nextLine();{}

            if(choice.equals("SOUTH")){
                System.out.println("\n\n\n\n--TERMINAL_LOG--\n\nI FOUND THIS HANDHELD TERMINAL LOG FIGURED I'D\nPUT IT TO SOME USE.

            choice = scan.nextLine();{
            }
            if(choice.equals("EAST")){
                System.out.println("\n\n\n\n--TERMINAL_LOG--\n\nI FOUND THIS HANDHELD TERMINAL LOG FIGURED I'D\nPUT IT TO SOME USE.

                System.out.println("\n\n\n\n--TERMINAL_LOG--\n\nI FOUND THIS HANDHELD TERMINAL LOG FIGURED I'D\nPUT IT TO SOME USE.

            choice = scan.nextLine();{
            }
    }
}

我似乎无法弄明白，但我认为“if”语句相互冲突。当我运行它时，键入“NORTH”，然后键入“FARTHER”或“EXPLORE”，命令提示符变为空白。它不会做它应该做的......除非你输入“INVENTORY”。然后它完美地运作。如果我将“choice equals INVENTORY”的位置与任何其他“Choice equals”切换，它会再次发生，除非它再次成为顶部的“if”语句。我在Notepad ++上键入它并通过命令提示符进行编译。提前谢谢。

编辑：根据一些评论，我忘记了，我忽略了添加我对java的生锈，我需要具体细节。如果可以的话，像婴儿一样带我走过去。如果麻烦太大，请跳过我的问题。

编辑：我删除了大部分不需要的括号。如果我还有一些，请告诉我。这就是我所拥有的，它几乎完美地运行和编译。

测试。完美地工作。

看起来你来自Basic / Pascal等程序语言。

要允许扩展和更多房间，您应该将功能分解为类。

位置 - 详细说明玩家所在的位置

退出 - 从房间有效退出（添加到该位置的退出列表）

项目 - 房间或库存中的任何项目

命令 - 可能是退出的超级类，详细说明可以用某些东西做什么。

这只是一个开始的想法。然后，您可以拥有一个包含在开始时加载的房间等的文件，这样您就可以使用一个引擎来制作多个RPG级别/冒险。 （你甚至可以链接图形和声音）

如果你想看看像TinyMuck（C / C ++）这样的东西是怎么做的，你可能会有更好的想法 - 那里有一个Java版本的MUD / MUCK，它主要面向对象。

另一方面，这是代码的清理版本

顺便说一下，没有任何循环可以循环来循环执行命令。

答案 1 :(得分：0)

我很抱歉我的错误回答。我再看了一眼，我不认为那些if语句是嵌套的。 NORTH if语句在print语句之后立即结束。因此，如果你不说北方，它就不会跳过与询问行动有关的if语句。

此外，我认为您的问题是，当您不说库存时，会发生什么，它不会崩溃。它实际上只是要求另一个输入。但由于没有提示，看起来它没有做任何事情。

我认为代码看起来应该是这样的:(你应该根据自己的目的进行编辑）

public static void main(String[] args){
  String choice;
  Scanner scan = new Scanner(System.in);
  System.out.println("text");
  choice = scan.nextLine();
  if(choice.equals("NORTH")){
    System.out.println("text");
    choice = scan.nextLine();
    if(choice.equals("INVENTORY")){
      System.out.println("text");
    }

    if(choice.equals("FARTHER")){
      System.out.println("text");
    }

    if(choice.equals("EXPLORE")){
      System.out.println("text");
    }
  }
}
