[C++]Screenpong

[defkult]

This program simulates pong on your screen using the sides as walls and the mouse as the ball. Have fun. By the way, does this forum allow malicious source codes?

Yes, it does.

Is there any difference between INT and int? I see you used caps for the Collision functions.

[defkult]

Nope. I just use caps for things like collision functions. And if i needed to store a variable like 3, I use lowercase.

[Riddle]

Ah. Ok.

Had me wondering for a while there.

[defkult]

No problem. It was fun making this.
