The first video shows off the following demos (in order):
- Racing Game: A very simple ActionScript 3 racing game, most notable feature here is path hit testing which is used by the game to implement collision detection.
- Box2D Demo 2: A few more complicated Box 2D scenes. There is a sight delay at startup while the JIT compiles the code, but then the simulations are fairly smooth.
- Box2D Truck Demo: Same as above.
- Truck Game: This is a fairly complex Flash game that uses Box2D internally and has a lot of graphic assets. The short stutter at the beginning is because of a very large SVG shape that is displayed briefly, it however takes a long time to parse and render. During the loading screen (right before the game starts) the game renders all of its vector graphic assets into bitmaps which are then composited during the game. The game itself is definitely playable.
The second video shows off Shumway running the YouTube Flash player. It doesn't work completely right but it is able to at least display the video. This is using a special build of FF that uses GStreamer.
