So, I'm working on my new project which is a game that there are two balls. One red, and one blue. You must draw a line to prevent them from touching.
I have gotten the balls, and bouncing to work and I just got the lines to work.
I just need help or ideas on how to get the balls bounce off the line.
I can use a similar code to the one I used for the edges of the screen but I'm thinking there might be issues since the line wont be horizontal or vertical. They might be diagonal.
Any ideas are welcome!
