i really need some help.
i am using this tutorial
i am not sure what to do when the tutorial says
"First of all, we can set the balls setMotion() method up in the forms constructor with x and y set up to 3.0. This will move the center of the ball 3 pixels right and 3 pixels down. Now in the forms button event, we call the balls move() method and invalidate the screen to redraw it. So we have our first moving ball."
the download source files are missing for 2 sections...
part of the code is here
can some please help.
thanks in advance
