HW #19

[chasestarr]

In this homework we will practice applying friction. Look at this video to get a refresher on friction. Grab the newest mover class from here.

Create 4 different colored rectangles in the pattern of the image below. If your object is within one of these quadrants, apply a unique drag force. The mover object should randomly spawn anywhere along the x-axis and at y = 100. When the mover is above the liquid, apply a wind force in either a constant direction, or a random direction. Take a look at the image below.

Can I copy and paste fragments of my previous projects?

[chasestarr]

I recommend typing everything out, but yes - basing your homework on previous projects is fine.

Thank you.
