Getting collision correct..

Hello all,

I am writing a simple game and so far I have 2 files, a Main file and a Dog file <-- please do not ask why dog, it was the first thing that came to my head.

anyway, here are the files:


Main Class

Code :

---

package Gamer;
 
import java.awt.*;
import java.awt.event.*;
 
import javax.swing.*;
 
 
 
 
 
public class Main extends JFrame{
 
    private Image dbImage;
    private Graphics dbg;
 
    static Dog d1 = new Dog(200,200);
    static Dog d2 = new Dog(50,50);
 
 
 
 
    public Main(){
        setSize(600,600);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setResizable(false);
        setVisible(true);
        addKeyListener(new AL());
 
    }
 
    @Override
    public void paint(Graphics g){
        dbImage = createImage(getWidth(), getHeight());
        dbg = dbImage.getGraphics();
        paintComponent(dbg);
        g.drawImage(dbImage, 0, 0, this);
    }
    public void paintComponent(Graphics g){
 
        d1.Draw(g);
        g.drawImage(d1.getImage(), d1.getX(), d1.getY(), null);
        g.drawImage(d2.getImage(), d2.getX(), d2.getY(), null);
 
 
        repaint();
    }
 
    public class AL extends KeyAdapter {
        @Override
        public void keyPressed(KeyEvent e){
            d1.keyPressed(e);
           // d2.keyPressed(e);
        }
        @Override
        public void keyReleased(KeyEvent e){
            d1.keyReleased(e);
           // d2.keyReleased(e);
        }
    }
 
	public static void main(String[] args) {
 
		Main shoot = new Main();
		Thread d1t = new Thread(d1);
		d1t.start();
		Thread d2t = new Thread(d2);
		d2t.start();
 
	}
 
}

Dog class

Code :

---

package Gamer;
 
import java.awt.*;
import java.awt.event.KeyEvent;
 
import javax.swing.ImageIcon;
 
 
public class Dog implements Runnable{
 
	int x, y, xDir, yDir, itX,itY;
	Image im;
	boolean  MoveIt = false;
 
	public Dog(int xv, int yv){
 
		im = new ImageIcon("C:\\OtherStuff\\enemy.png").getImage();
		x = xv;
		y = yv;
		itX = 500;
		itY = 300;
 
	}
 
	public Rectangle getBounds() {
		return new Rectangle(x,y,40,40);
	}
 
	public void Draw(Graphics g) {
        g.setColor(Color.BLUE);
        g.fillRect(120, 120, 40, 10);
        g.fillRect(160, 120, 4, 7);	
        g.drawImage(getImage(), getX(), getY(), null);
 
	}
 
	public Image getImage() {
		return im;
	}
 
	public int getX() {
		return x;	
	}
 
	public int getY() {
		return y;	
	}
 
    public void move(){
        x += xDir;
        y += yDir;
        if(x <= 0){ x = 0; }
        if(x >= 550) { x = 550; }
        if(y <= 0){ y = 0; }
        if(y >= 550) { y = 550; }
 
    }
 
    public void setXDirection(int xdir){
        xDir = xdir;
    }
 
    public void setYDirection(int ydir){
        yDir = ydir;
    }
 
    public void keyPressed(KeyEvent e){
        int keyCode = e.getKeyCode();
        if(keyCode == e.VK_LEFT){
            setXDirection(-1);
        }
        if(keyCode == e.VK_RIGHT){
            setXDirection(1);
        }
        if(keyCode == e.VK_UP){
            setYDirection(-1);
        }
        if(keyCode == e.VK_DOWN){
            setYDirection(1);
        }
        if(keyCode == e.VK_SPACE){
            MoveIt = true;
        }
    }
    public void keyReleased(KeyEvent e){
        int keyCode = e.getKeyCode();
        if(keyCode == e.VK_LEFT){
            setXDirection(0);
        }
        if(keyCode == e.VK_RIGHT){
            setXDirection(0);
        }
        if(keyCode == e.VK_UP){
            setYDirection(0);
        }
        if(keyCode == e.VK_DOWN){
            setYDirection(0);
        }
    }
 
    public void goTo() {
 
    	     if (x < itX) { setXDirection(1); } 
    	else if (x > itX) { setXDirection(-1); } 
    	else              { setXDirection(0); }
 
    	     if (y < itY) { setYDirection(1); } 
    	else if (y > itY) { setYDirection(-1); } 
    	else              { setYDirection(0); }    	     
 
    	if((x == itX) && (y == itY)) {MoveIt = false; }
 
    }
 
 
	@Override
	public void run() {
        try{
            while(true){
            	move();
            	if(MoveIt) { goTo();}
                Thread.sleep(5);
            }
        }catch(Exception e){System.err.println(e.getMessage());}
 
	}
 
}

Please note that the commented out parts are/were just random tests I was doing to see what would happen kind of things..

The problem I have is that I cannot seem to figure out how to put in a collision detection between 2 dog objects? where would I put it?

I was gonne use the if(d1.intersects(d2))... but I cannot put it into the dog class as d1 and d2 are not objects in that class, and the main class I did not put a while loop so I am a bit lost as to where it should go?

Should I move the move function to the main class?

Thank you for any help

Bob
