Not bad Smiley  Needs a scoreboard

Take a look at a similar program for some ideas / comparisons / example code.

The pad is at the very bottom of the window. It's easy for the mouse to leave the window while trying to catch a ball. If you leave some blank space below where the pad is located, it's going to be easy to control with the mouse.

Nice first job!
One thing: dist(x1,y1,x2,y2) gives you a distance between two points, which is fine for testing circle collisions but will not be quite right for ball-to-rect collisions.  For that, you need to see if:
a) the ball is below a certain line AND (&&):
b) the ball is within the left and right x-limits of the paddle/catcher

I put a similar progam here with source:

Yes, Ban

i realized that it does not work well on collisions between a circle and rectangle. can you give me more thought on how to enhance it up, if you are available thanks for your note, anyway Smiley
