Richard and I have launched our 18th Bit for Bits of Blender. This one is a whirlwind introduction to Logic Bricks and the game engine. I've begun teaching him about the game engine as a prepare a course for CartoonSmart.com. He couldn't resist having us show a little on it.
One thing I noticed in the video is that the velocity for one of the objects is faster than the framerate of the capture software. The software was capturing at 15fps, the game engine was running at 60fps, and I'm not sure what the YouTube encoder does to the fps.
