    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

u/zanella

Wait, how did you call .join without parentheses?
u/jylikangas

That's ES6 stuff - I'm passing the function a template literal by using back-ticks
u/AnnanFay

Hmm, that's a neat trick.

If you're interested in using images http://具.pw might be useful.

Hey hg, BTW, I deleted your Zelda sound dweet because we're trying to apply the policy of not playing unsolicited sounds. (It's still acceptable to play sounds on user interaction.)
u/AnnanFay

I added the http because I thought it would turn it into a link. Probably should have just linked http://具.pw/about.html
u/hg

@magna, apologies. I did think it was a bit annoying.

Golfed-ish... Maybe learn some new techniques fromit IDEK, https://www.dwitter.net/d/7041
u/BirdsTweetCodersDweet

See the link in the comments of that one as well. Shortened it some more.
u/triclops200

The first one had golf that kept the output the same, but the second has output changes (the /3.6, for example, was there to approximate center of screen y), otherwise, good golf
u/snydej

Note that "540" is shorter than "w/3.6" ;)
