#2Wow, very nice :-)

#3It's a bit slow. I suggest 1) Use existing table instead of creating a new table at each frame/interval. 2) Or use Canvas because DOM is so slow 3) requestAnimationFrame instead of setInterval

#4Maybe it wasn't clear in the original article [1], but what you see inline are javascript implementations of the effect - there is a link to the source code at the end:

#5I first learned to do this effect in 1999 thanks to the incredible Denthor/Asphexia tutorials. I looked forward to new releases of these that my friend would (somehow) get and give to me on a floppy disk.
Most of them were in Pascal, but the fire one was in asm (http://archive.gamedev.net/archive/reference/articles/articl...) - it was the first time that assembler really clicked for me!

Open Source community is awesome, someone already made a Pull Request about this: https://github.com/filipedeschamps/doom-fire-algorithm/pull/...

Oh wow. Denthor's tutorials were very good. Brings lots of good memories. Too bad this culture was overrun by internet.

For canvas I’d be curious which would be faster: grabbing an ImageData and continually update then set or use fillRect.

#9But can you implement JavaScript in Doom?

Y'know, I wouldn't be surprised.
