LOL, nice :D
u/lienthealien

D: it's incredible. I still don't fully understand whats going on the begginning of the for.
u/p01

Thanks! Touching the width ( or height ) of a canvas resets it. c.width|=i=48; ⇒ Sets i to 48. Does a binary OR of 48 on the width of the canvas and resets ( it mostly clears it ) the canvas
u/sfz

redrawing the canvas and initializing i, nice!
u/lienthealien

u/donbright

u/iverjo

Hmm, why can one not do '🐸🌷☁️️'[k]? Is it simply because they are not single-byte characters?
u/p01

@iverjo: Exactly. Although I should have used [...'🐸🌷☁️️'][k] to save 3 bytes

looks like all-grey on iOS...not sure what's going on
u/taupelink

I think it has to do with the fillRect function and fractional widths. I wonder whether tiny widths get rounded up in iOS, filling in blanks that appear on other systems
