我曾经在TI-BASIC中编程,并经常使用goto语句。我已经转向学习java,并且无法弄清楚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,我没有想法如何解决这个问题......

答案 0 :(得分:3)
Java没有goto
声明,您也不需要声明。
目前,您将房间表示为方法。当前房间作为调用堆栈的最顶层。预先访问的每个房间都在那之下。这种方法足以用于短期冒险游戏。但是:
另一种方法是考虑游戏中的对象是什么。你有:
这些对象可以定义为Java类或枚举。房间和房间之间的连接构成了graph中的节点和边缘。
您的方法可以是操作,例如将用户从一个房间转换到另一个房间,或者提取或使用库存项目。
