Mission briefing
In this project, we focus on the physics engine. We will build a basketball court where the player needs to shoot the ball in to the hoop. A player shoots the ball by keeping the mouse button pressed and releasing it. The direction is visualized by an arrow and the power is proportional to the duration of the mouse press and hold event.
There are obstacles present between the ball and the hoop. The player either avoids the obstacles or makes use of them to put the ball into the hoop. Finally, we use CreateJS to visualize the physics world into the canvas.

The following screenshot shows a player shooting the ball towards the hoop, with a power indicator:
Why is it awesome?
When we build games without a physics engine, we create our own game loop and reposition each game object in every frame. For...
