| By using a sound's x and y coordinates, this function pans the sound, and decreases the volume the further away it is from the middle of the screen. There is also a 'spread' variable that controls the volume 'dropoff'...|
Also, it changes the pitch of the sound to make each sound a little different from the past one. The distance formula is needed, so it's added as well.
