This is progress report 2 of the drawing app series. I have cleaned up the code to make the game run more fluidly as well as incorporated a new concept in the collision detection that makes the collision smooth.
Frame rate might seem slow but I am on a MAC G5 that's about 5-6 years old and running the physics app + the recording app is intensive.
I have seen frame rates of around 400-500 FPS on other computers!
Stay tuned to my videos for more info on the development.
