I got the Racket + Game of Life demo to work on a 50 x 50 grid at a framerate that was semi-tolerable, and by semi-tolerable I mean 10 FPS on this ancient machine. I guess that's 2500 sprites on a 1000 by 1000 canvas, and I'm redrawing the whole thing every time (but now onto the same bitmap). A 30 x 30 grid, on the other hand, is plenty fast.
The slow bit at this point is the blitting of each sprite onto the canvas.
@cwebber sharing is caring?
@cwebber I'm curious how a port to love2d would compare, and possibly how it would look in Urn
@technomancy Good point... I should upload it! Here it is: https://gitlab.com/dustyweb/racket-life
Just check it out and run ./run-life.sh. All you need is Racket installed and it should chug along.
@technomancy Okay, and now you can set the grid size from the command line:
./run-life.sh 25 50
@technomancy Sure... I guess I should push this git repo live!
