Bouncing Ball in a Cage

• • Create a program that is a ball that moves across the screen until it reaches an edge of the screen, then have it change direction “bouncing” backward like this:

Hint: Create variables x & y to keep track of your position on the screen. Create variables xDirection and yDirection to keep track of how much to move left/right or up/down each loop:

x += xDirection;

y += yDirection;

when you hit a wall, change direction:

if (x> width)

{

xDirection = xDirection * -1;

}
