Drop requirement for x,y,time of final collision in favor of just X and Y of exit point.
"Catcher" at designated exit point catches ball.
In diagram, this is a tube with initial angle matching the exit angle of the ball, feeding to a horizontal section that exits either left or right, depending on whether the ball exits travelling left or right.
In 3D, this is a tube similarly oriented, but with regular holes so we can see the ball moving down the tube.
Catcher "misses" result in further bounces off of catcher tube and even obstacles if this is physically correct, till ball exits playing area.
Ball trajectories now include include movement in catcher till off-stage. Next ball still fires 1 second after current ball enters catcher.
Modify Bounce to use "catchers"
