With the help of B+'s reflection math code, I decided to make a Pong Clone today. You play against the computer using your mouse. First to reach 10 points wins. B+, I added your name to the welcome screen. Tell me what you think. It was a bit tricky to make it not too easy but also not impossible, I believe I found the right middle ground. There's a photo of it below.  Thanks for the help B+, I've always wanted to make my own Pong. I know most of them have rectangle rackets but I found it's more enjoyable to aim the ball with a round racket instead.

Hi Ken,
Looks pretty good. Don't need the delay or to show the white line of collision when a ball hits a paddle.
Do need a little delay before throwing out the next ball after someone wins a point and specially at start of game. Give human a chance to get his bearings.
Maybe a count down 3, 2, 1...?

By the way, in case you were wondering, I didn't use your A.I. for the computer. I calculated the Y distance from his racket to the ball and the further the Y distance, the faster he goes. But I had to make somewhat of an offset to not make it impossible. lol

Talking about angles. I made it so it doesn't start out at the most extreme angles, around 10 degrees before and after the tightest angles, so people wouldn't sit there waiting for it to bounce back and forth a million times. LOL
Sometimes it can catch up, but yeah sometimes it can't.

You were right Coolman, sounds really livens it up, thanks for the recommendation. I also made the delay longer from 1/2 second to 1 second before each ball starts.
B+, I didn't know that putting the Sound command in a Sub helps the flow of the program go on and not stop, that is so cool! I saw you did that on your Air Hockey game. I used a bit of a different sound than yours I think.
Here is the update:
