Adventures of Ball
This was a project where we were only supposed to do very simple things with Unity. I designed my game around what was expected for the project. The big thing was extra credit if you used physics in a meaningful way. My idea came from that.
To be honest, it turned out a lot different than what I was envisioning, but I think it turned out better than I thought it would have. We only had a couple of days to make the game, so I kept it really small. I think it took me about one or two days to make, then I just tested it on people until the project was due.
The one thing that was causing me a lot of trouble, was when the ball came to a stop, it would just stop forever. I could not figure it out. I thought it was getting stuck in the walls. Turns out, rigidbodies go to "sleep" when they stop moving, so that all the physics calculations aren't wasted on it. I had to explicitly "wake" it up so that it would be affected by physics again. That was fun.
Not much else to say; it is a very simple, but actually pretty fun, game.
