Default Help in Java? - 11-20-2011, 03:39 PM

Finally moving to the realm of Java game design, I found a few troubles. After a good month or so I managed to actually get my Images to draw on the JFrame! But now I need to get the keyinput....

If anybody here knows some Java, I would definately love to get some help with this. Here's the code:

//by Nighthawk
// - app launching point and GUI setup

import javax.swing.*;

public class Main extends JFrame{
	Tuna panel = new Tuna();
	public Main(){
		setTitle("Java Game");
		setSize(800, 600);
	public static void main(String[] args){
		Main start = new Main();
//by Nighthawk
// - Player Information

public class Apples{
	public int x;
	public int y;
	public Apples(){
		x = 25;
		y = 75;
	public int getX(){
		return x;
	public int getY(){
		return y;
//by Nighthawk
// - the JPanel that does everything

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class Tuna extends JPanel{
	public Image player;
	public Image bg;
	public int x;
	public int y;
	public boolean painted = false;
	Apples playerClass = new Apples();
	public Tuna(){
		ImageIcon img = new ImageIcon("C:/QuickFiles/Java/BG.png");
		bg = img.getImage();
		ImageIcon img2 = new ImageIcon("C:/QuickFiles/Java/Player.png");
		player = img2.getImage();
		x = getX();
		y = getY();
	public void keyPressed(KeyEvent e){
		int keycode = e.getKeyCode();
		case KeyEvent.VK_LEFT:
			x = x + 1;
		case KeyEvent.VK_RIGHT:
			x = x - 1;
	public void init(){
			if(painted == true){
	public void paint(Graphics g){
		g.drawImage(bg, 0, 0, null);
		g.drawImage(player, x, y, null);
		painted = true;
And, don't question the class file names (well actually this is a project that I use in the workspace for various things, naturally having classes that fit one project would confuse me on another one, so I made some names that would make sense across all the projects I do. On a real game I would actually name the class files something reasonable, such as 'JPanel.class'

Thanks for any help,
