What's the best solution for providing proper parameters (x,y) for move() function? "Move() function" we use it to move the ball in the Breakout game.
Move is a pre-defined function in the SPL. It requires 3 parameters: a type GObject (something to move) and a dx parameter (an x plane displacement) and a dy parameter (a y plane displacement).
Read up on the SPL Objects and Functions here, and re-watch the walkthrough videos presented by David relating to "bounce". The pset specification has a numbered item delving into making the ball move, complete with how to utilize the drand48 function to randomize initial movement of the ball; you should re-read that section as well.
