【问题描述】:
我以前用 TI-BASIC 编程,经常使用 goto 语句。我已经开始学习 java,但不知道如何将程序的执行发送到另一行。
这是我的完整代码:
package inputs;
import java.util.Scanner;
public class Inputs {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
String greeting = "Welcome to a new choose your own adventure game!";
String help = "Use commands such as up, down, left, and right to move around the world";
String error = "You can't do that";
room1();
}
public static String getNextLine() {
Scanner scan = new Scanner(System.in);
return scan.nextLine();
}
public static String getNextWord() {
Scanner scan = new Scanner(System.in);
String base = scan.nextLine();
String command = base;
//differentiate capital and lowcase
if ("north".equals(base)){
command = "North";
}
if ("south".equals(base)){
command = "South";
}
if ("east".equals(base)){
command = "East";
}
if ("west".equals(base)){
command = "West";
}
return command;
}
public static void room1(){
System.out.println("There is a faint smell of rotting flesh around you. you look hazily around the room. There is a door to the north. It may be your way out...");
String command = getNextWord();
while(1==1){
if ("North".equals(command)){
hall();
}
else{
System.out.println("You can't do that.");
}
}
}
public static void hall(){
System.out.println("You are in a hallway. The hallway continues in a northerly direction to another room. There is a room to your left");
while(1==1){
String command = getNextWord();
if ("North".equals(command)){
room3();
}
if ("East".equals(command)){
room2();
}
if ("South".equals(command)) {
room1();
}
else {
System.out.println("You can't do that.");
}
}
}
public static void room2(){
while(1==1){
String command = getNextWord();
if("get".equals(command)){
System.out.println("You picked up the key. Maby there is a door somewhere");
}
}
}
public static void room3(){}
}
如您所见,我正在尝试创建一个有 4 个房间的文字冒险游戏。如果可能的话,我还想在 room2 中找到一个在 room3 中使用的密钥。老实说,我不知道如何解决这个问题......
*编辑 为了响应被标记为可能的重复,我的问题要求针对我的特定程序采取特定的行动方法,而不是一种全面的行动方法
【问题讨论】:
-
将房间转换为类并在主类中实例化它们
-
您应该了解
else if的用法,而不是一系列else语句。找到匹配项后,没有理由进行大量比较。 -
请参阅下面 Kevin Hooke 的答案 - 您确实需要按照 java 教程作为第一步。
-
问题是我希望能够跳转到不同的方法而不返回上一个方法。如果有办法做到这一点,我宁愿这样做。
