An empty road is no fun! A good program is full of life and action. To make things move, we need to tell the computer to update the world over and over, very fast. This is called a **game loop**.

Think of it like flipping through a comic book. Each page is a little different, and when you flip them fast, it looks like the characters are moving. The game loop "draws" a new picture for you many times every second.

Now, your car is moving! We've started the loop.
