My raycast engine in Javascript needs a few more lines and works a little bit different, but gives also impressive results I think :) .

Love that you referenced Comanche ... my favorite helicopter game ever. Nice work on the JS side also!


The graphics were impressive, but the gameplay never touched me. Comanche 3 was much better.


I really like how your code uses much less cpu than that of the article. whats the trick ?


Don't know. But here some possibilities:

1. No fullscreen

2. I update the screen only if a key is pressed.(No rain, that has to be rendered all the time)

3. I don't use any costly canvas functions. I render everything myself in a pixelbuffer.

4. Typed arrays


It's #2. Redrawing at 60hz (or as close as the machine can come) is what hits the cpu so hard.


No, I don't use requestAnimationFrame right now. I think when I wrote it, it was not supported by IE. But can't remember.

I calculate as close as the machine can but with a window.setTimeout(Update, 0); in order to be responsive.


Very cool. Comanche was an excellent game too.


Love it! Thanks, just linked from the article.


Hey thanks, that was fast.
