Making a 3D modeler in C in a week

Yes, the background is odd but the foreground is definitely not smooth. I see small little jitters occasionally. At one point I had to wait 15 seconds for it to jitter, though.

Yes the back and foreground is quite jittery for me on Firefox, and I'm almost certain its the browsers own requestAnimationFrame that's the problem.

Update: Although, having a closer look at the scene, I see its pixel art, so I bet the author is snapping floating point positions to a pixel point to prevent sub pixel blurring.

Another small update: I was sure requestAnimationFrame was locked to 60fps, but I noticed on Chrome the other day it was 144hz, the full speed of my monitor.

yeah, http://canonical.org/~kragen/sw/dev3/qvaders is unplayable on 120-hertz monitors because i'm running the game physics from raf ;)

Also noting that it's choppy on iPhone, but it's really barely noticable. Cool little game!

thanks! the choppiness is for the same reason; if the frame rate drops temporarily due to cpu load or whatever, the vaders move slower
