TO THROW THE BALL

It may seem that this kind of laboratory work for a basketball player. View, you need to throw the ball in the basket, building the trajectory of its flight and bothering to throw that obstacles did not prevent the execution of the task. After each successful throw, the basket changes its location.

So, take the ball (click and hold the mouse button), drag to the side of the basket, watching the marker of the future trajectory of the flight and when you are satisfied, release the button. Note that for collisions with the walls here give extra points, and the ball bounces perfectly from the walls, therefore, other things being equal, try to use this property.
