制作一个简单的基于文本的角色扮演游戏比预期的要难

Question

Sooooo...我正在使用 JAVA 构建基于文本的角色扮演游戏，但出了点问题.... 它会编译，它会运行，但是......好吧，这很难解释。我先把代码贴上去

    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();{
                if(choice.equals("INVENTORY")){
                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("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.

                choice = scan.nextLine();{
                }
                if(choice.equals("EXPLORE")){
                System.out.println("\n\n\n\n--TERMINAL_LOG--\n\nI FOUND THIS HANDHELD TERMINAL LOG FIGURED I'D\nPUT IT TO SOME USE. TODAY IS, ACCORDING TO THIS, THE 15TH OF JAN, 2644.\n\nI TRAVELED WEST AND FOUND AN ABANDONED SHACK.\nSHOULD I SEARCH IT FOR LOOT OR MOVE ON?\n\n(options: SEARCH,MOVE)");}}
                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.

            choice = scan.nextLine();{
            }
            if(choice.equals("WEST")){
                System.out.println("\n\n\n\n--TERMINAL_LOG--\n\nI FOUND THIS HANDHELD TERMINAL LOG FIGURED I'D\nPUT IT TO SOME USE. TODAY IS, ACCORDING TO THIS, THE 15TH OF JAN, 2644.\n\nI TRAVELED WEST AND FOUND AN ABANDONED SHACK.\nSHOULD I SEARCH IT FOR LOOT OR MOVE ON?\n\n(options: SEARCH,MOVE)");}}
            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。它没有做它应该做的事......除非你输入 "INVENTORY"。然后它完美地工作。如果我将 "choice equals INVENTORY" 的位置与任何其他 "Choice equals," 的位置切换，它会再次发生，除非它再次成为顶部的 "if" 语句。我在 Notepad++ 上输入这个并通过命令提示符编译。提前致谢。

编辑：根据一些评论，我忘记了我忘记在 java 中添加我是半生疏的，我需要细节。如果可以的话，请像对待婴儿一样陪我度过难关。如果太麻烦，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。这是我所拥有的，它运行几乎可以完美地编译。

已测试。近乎完美。

Answer 1

看来您是从 Basic/Pascal.

这样的程序语言过来的

要允许扩展和更多房间，您应该将功能分解为类。

位置 - 玩家所在位置的详细信息

出口 - 房间的有效出口（添加到该位置的出口列表）

物品 - 房间或库存中的任何物品

命令 - 可能是 Exit 的超类，详细说明了可以用某物做什么。

这只是一个开始的想法。然后你可以有一个包含在开始时加载的房间等的文件，这样你就可以使用一个引擎来制作多个 RPG levels/adventures。（您甚至可以 link 在图形和声音中）

如果你想看看像 TinyMuck (C/C++) 这样的东西是如何工作的，你可能会有一个更好的主意——有一个 Java 版本的 MUD/MUCK 那里是高度面向对象的。

另外请注意，这是您的代码的清理版本

    import java.util.Scanner;

       choice = scan.nextLine();
    }

顺便说一下，它没有任何类型的循环来一遍又一遍地执行命令。

Answer 2

对于之前的错误回答，我深表歉意。我又看了一眼，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，如果您不说 north，它就不会跳过与询问操作相关的 if 语句。

另外，我认为你的问题是当你不说库存时，它不会崩溃。它实际上只是要求另一个输入。但是因为没有提示，所以看起来好像什么都没做

我认为代码应该如下所示：（当然，您应该根据自己的目的对其进行编辑）

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");
    }
  }
}

制作一个简单的基于文本的角色扮演游戏比预期的要难

Making a simple Text-Based RPG is harder than expected

java

if-statement

javac

notepad++
