- Discuss and point out code that looks familiar

- Identify code that looks new

- Try to figure out what will be the output

​

Run! Any surprises?

​

Investigate figure out these things:

​

- Where and how is the cars array used?

- How many cars can be shown? is there a limit? 

- How is the car class defined?

- What is different about the variables in the car class?

- What functions can a car "do"?

- How does the car reappear on the other side of the canvas?

- How do cars move at different speeds? direction?

- How does the main draw function use the Car class to draw them?

- Why is display() and how is it different from move()?

​

Modify it!

- Make a different looking car.

- Make all cars move faster or slower.

- Bonus: make all cars speed up or slow down with keyboard events

​

Make a new animation based on this example:

​

- Rewrite your planet objects into a class

- Create  bouncing balls with mouse clicks

- Make moving clouds that move off the screen

- Make a monster class that spawns new unique monsters each time
