This case is from the Scratch tutorial.
In the game, the ball will bounce in the canvas.
if it is touched with the paddle, which will run with the mouse, it will turn to the contrary direction and continue to move. the score will add one.
and if it drops on the red banner, that means it is on edge and will bounce.
the code for the ball is like this:

1. the ball move and bounce freely.
