    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.

..But less authentic. Remaps the pixel positions rather than texture, which gives "free" antialiasing, with spare space to correct the spin.
u/pavel

Oh yeah, nice. This is definitely a better way of doing it. The other mapping has an incorrect center that I have to waste characters to correct.

-2 char using S(t%3.14) to bounce and inlining the single Math.abs call

What a clever trick, using modulus pi of t, to only get the positive part of the sinus curve

3.2 works fine, while 3 and 3.1 looks wrong

Sometimes when I'm bored, I use dwitters "random" function. Today it lead me to this dweet by u/KilledByAPixel :-) - I had to try to golf it to see if i could fit it without unicode compression. I also tryed the linked game "Bounce Back!" what a great game in only 13k. By the way, u/KilledByAPixel congrats on winning JS1024.fun - greate game in only one freaking kilobyte of incompressable javascript code! What a feat!

u/KilledByAPixel

Thank you and nice work!
u/tomxor

It's a very nicely crafted game, I played it quite a few times :)
