Developing Tile Puzzle Game in Java

Post Views: 8,577

Greetings! Friends, Today I am going to explain how to Develop Game in Java. The game which I am going to develop is a Tile Puzzle Game. In this game development we are going to use below classes :-

java.awt.Image
java.awt.image.BufferedImage
javax.swing.ImageIcon

Here Image class is used to hold image resource while BufferedImage and ImageIcon are used to split image to multiple images.

In this game there is a default image which is loaded automatically but you can load your own image also at runtime using load button in the user interface.

In this game I am going to create three classes first one is Game.java where all game logic coded ie. loading image, starting game, stopping game, etc. second one is Help.java which is used to show solved puzzle for hint and last one is Timer.java which is used to store time.

So here is the code

Game.java

import java.awt.Graphics;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.MouseEvent;
import java.awt.image.BufferedImage;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JOptionPane;
