Thanks for the heads up. I'm sure it does -- it's probably implemented in a simular way though in complied code. Plus IIRC I had to do the matrix transformations by hand in Javascript (because you can't get the current transformation matrix out of a canvas sadly) whereas this method will use the ones that have already been applied in the current context. Big win! George:

Other techniques can be explored for hit tests. For example, following this (non HTML5) tutorial. I found this while looking at this HTML5 asteroid game.

A very useful check on how browsers are keeping up and an excellent distraction (for those of us over 45..) as well. Mike Absolutely brilliant Doug.

Would be wicked to be able to play on my desktop! I suspect we could help you increase distribution too...could be easy and fun. M You should turn this into a Pokki.

Any time I add this.context.strokeStyle to a particular function it changes the stroke color for the entire game. I'm not sure why that happens, any pointers would be appreciated. Specifically how would you change the color of the text in the game? I’ve been poking around the code trying to figure out how to change the strokeStyle color for different elements in the game.
