Hey guys, I'm in an intro to programming course for school and am in need of some help, If anyone has ever used http://processing.org/ before, you could probably help me out.

I'm just doing a simple drawing of the beach at the moment but I'm not really sure how to use the mousePressed() function. All I want to so is have the break of the waves go in and out and have the clouds move across the sky. Shouldn't be too hard but I'm just confused how to do it.

Thanks for the help.
