Paint that works in fullscreen too

👍
u/ximavus

here's a 32 character golf: change the c.width/innerWidth and c.height/innerHeight with 3.4
u/ximavus

I checked how much it is and its actually 3.386243386243386 but 3.4 is pretty close
u/lewdev

I didn't want a hard-coded version because this solution is much better than this d/34332 which uses getBoundingClientRect to find the accurate position of your mouse no matter the size of your canvas. But I'll keep that in mind for future dweets.
u/ximavus

ok
