All Implemented Interfaces:

java.lang.Runnable

public class BallMoverThread

extends java.lang.Thread

Everything moved from an innerclass in the PongPanel: that's why there's no real interface between this class and the PongPanel but merely direct access of package-protected or public members.

Bugs: many, among them:

• when bricks aren't zapped right away, the ball may get partially inside the brick, which can cause strange phenomenons, such as the ball going hitting the bricks a lot of times from the "inside" and then going right trough the brick.
• If the ball has a straight vertical direction (zero horizontal speed), and merely "touches" a bricks short side with a pixel or so, it doesn't change direction at all, but still hits the brick, which lets you nuke a whole line of bricks in a single shot (try it by enabling the crosshair cursor and aiming such as the cursor is exactly one pixel from the nearest brick).
• base speed is only updated upon paddle hit
• in general, the speed things should be rethought
• there are many repaint() calls on each iteration, these doesn't do so much harm since AWT's RepaintManager collapses many of them, but it should probably save some CPU to do the repainting a little bit more nicely.
• Is a frequence of 50 iterations per seconds really necessary?

and so on...
