Nice to see everyone :) Hope your all hve a good day, Anyway, yeah as u can tell by the sibject im making a 2D shooter game using tiles. I'll paste wat ive done below, i just need to know if i can make the game work from what ive already got, of do i need to start again with a new design?? I really kjnow nothing about game programming, and hve really only been doing Java for 4 yr's im in yr 11. //War //My First Game //Nicholad Paul //Started 25 Febuary 2005 import javax.swing.*; import java.awt.*;

Actually all up im lost, i dont know where to go. Sorry for the length of this question, ive been on these forums for awhile now, and ive always got good responses, so thats why i came here. Thanks in advance for any help :)

To make the code easier to read can you do this:
use [ source lang = "java" ] and then place each class within it's own source tag?
I'll be able to help if you if I can actually read it easily.
BRING BACK THE BLACK (or at least something darker)

This Better?

It certainly looks like a repaint issue.
The problem is in the run() in bullet:
while(x >= dx){	g.drawOval((int)bx,(int)by, 10, 10); //RIGHT HERE IS THE PROBLEM	by = by + (10 * m);	bx = x;	repaint();	x = x - 10;}

What is happening is that the Graphics object g is not getting cleared before the next repaint. If you have ever turned on 'mouse trails' in the mouse control pannel, this is the same thing.

In order to fix this, I would suggest moving away from using the default pane paint methods and move to something like BufferStrategy.

One thing that most games have is the MainLoop. A typical main loop looks like this:
LOOP:  update objects  clear drawing buffer  draw objects to buffer  show buffer to screen  waitEND

With bufferStrategy you can implement this kind of loop.

Also with the main loop there are some pretty general objects like the Sprite object that most games have. In a Sprite object there would be a method thats something like 'drawMe()' and this way a managing class can just iterate through a list of objects and ask them all to draw themselves to the screen buffer. But the important thing to do is to clear the buffer before each show(). This makes sure that the objects get cleared, and don't leave a trail behing them.

THIS is a really good tutorial on general game form. It is step-by-step to create a Space Invader clone.

Hope this helps!
BRING BACK THE BLACK (or at least something darker)

So let me just get this right, ur saying that i should run a loop which does those things u listed. So when the player clicks the arrow keys or the mouse button do not repaint, just change the values, the loop draws all the graphics to the buffered image and then paints it? Is this wat u mean?

This tutorial is really great thank you soo much
