I learned a lot about rigid bodies while doing this project. I learned the difference between active and passive rigid bodies, and how to use them effectively. At first I didn't know that you couldn't have the cup active at the same time as the marbles inside of it. So I turned the cup into a passive after I simulated it and then made the marbles active. I still had trouble getting the marble to roll out of the cup, so I used a force and it worked. The see-saws were giving me trouble, because they wouldn't stop spinning. To fix it I added a spring to hold it down while the ball got to it. After that it all went downhill.
