Kelas : PBO A

World Of Zuul

Dalam tugas kali ini saya mengimplementasikan sebuah game bernama world of zuul. Game ini merupakan sebuah game explorasi antar room dengan setiap room memiliki exit dan deskripsi masing masing.

Link : GitHub

Terdapat beberapa class antara lain

import java.util.HashSet;

public class CommandWords {
private HashSet<String> validCommands = new HashSet<>();

public CommandWords()
{
validCommands.add("go");
validCommands.add("quit");
validCommands.add("help");
}
public boolean isCommand(String command)
{
if(command == null)
{
return false;
}

return validCommands.contains(command);
}
}

Class ini merupakan sebuah class yang akan memvalidasi apakah sebuah input merupakan sebuah command atau tidak

public class Command {
private String commandWord;
private String secondWord;

public Command(String commandWord, String secondWord)
{
this.commandWord = commandWord;
this.secondWord = secondWord;
}
public boolean isUnknownCommand()
{
return commandWord == null;
}
public String getCommandWord(){
return commandWord;
}
public String getSecondWord()
{
return secondWord;
}
}

Class ini merupakan sebuah class yang menyimpan command yang diinput dari user

public class Room {
private Room northExit = null;
private Room eastExit = null;
private Room southExit = null;
private Room westExit = null;
private String description;

public Room(String description)
{
this.description = description;
}
public void setExits(Room north, Room east, Room south, Room west)
{
northExit = north;
eastExit = east;
southExit = south;
westExit = west;
}
public String getDescription()
{
return description;
}
public Room getNorthExit() {
return northExit;
}
public Room getEastExit() {
return eastExit;
}
public Room getSouthExit() {
return southExit;
}
public Room getWestExit() {
return westExit;
}
}

Class ini merupakan room yang akan dieksplorasi dan menyimpan setiap exit melalui arah mata angin

import java.util.Scanner;

public class Parser {
private CommandWords commandWords;
private Scanner scanner;

public Parser()
{
scanner = new Scanner(System.in);
commandWords = new CommandWords();
}
public Command getCommand()
{
System.out.print("> ");
String input = scanner.nextLine();
Scanner tokenizer = new Scanner(input);

String first = null;
String second = null;

if(tokenizer.hasNext())
{
first = tokenizer.next();
if(tokenizer.hasNext())
{
second = tokenizer.next();
}
}

if(commandWords.isCommand(first))
{
return new Command(first, second);
}
else
{
return new Command(null, first);
}
}
}

Class ini merupakan class yang akan melakukan parsing dari input yang mentah (Scanner) dan membuat objek command yang akan mudah dibaca oleh game.

public class Game {
private Parser parser;
private Room currentRoom;
private boolean isPlaying;
private boolean addRoomInfo;

public Game()

Class in berisi logic dari gamenya. dengan menyimpan room yang sekarang 

public class Main {
public static void main(String[] args) {
Game game = new Game();
game.play();
}
}
