Pong, Need help with paddles and pause
Hello all. First off i just wanna say thank you to anyone who can help, as this is my first big code undertaking. I have the code below and the coding has gone fine except I need it bounce off if it hits the paddle (right now it goes right through), and then do block++ if it does. Im thinking i need to pass some functions by reference to accomplish this, but im not sure. Also anyone know how i can implement that pause function with the printLogo one? I want it to do printLogo, then pause for like 5 seconds, than start the game. Ive tried putting it every which way and I cant seem to get it to work. Thanks again!
Code:
