Hello sir,
I am interested in the pong game of yours. I read your description and I think I am going to provide you the code for the tennis ball bouncing on the ground, net and the bat. I can provide this with an accurate physics code of my own or the simplified version that just works. It's your choice. I can do the whole project and document the code for you as well. Anyway, the question is what graphics api is used? Opengl?, Or is it a simple CLI (command line interface). I'd be happy to work on this project with you. This project should take 2 days at max we can discuss about the price as well. Hope to have a chat with you. Thank you for reading it.
