    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.

Delete the last 4 chars in the compressed string and watch the ball wobble around like mad
u/tomxor

Yeah -V/8 is for velocity damping on Y. Which is necessary with velocity based collision resolution. An alternative that doesn't require this is verlet integration, but that requires far more characters.

Smoler Impossible Marble #Physics

u/tomxor

-11 bytes: Eliminated the intermediate k, moved some coefficients around, and swapped hypot for square values which is actually more stable for intersection resolution. Now it will never stop jiggling :D
u/magna

u/pavel

Currently traced pixel is part of the ball and part of the background therefore collision. Awesome trick. My first time seeing this.

Infinite hopscotch

u/Odog8

Thats nuts
u/Joachim

This 3D-like technique is useful for making single-direction ground textures. This is roughly how it works: A rectangle with a height of ~1px is drawn for every row of pixels on the screen. The width of every rectangle depends on how far down it is (their index). The x position of every rectangle is defined by this bit of code: T(z^z/i+t*9). This is then multiplied by their index to achieve a 3D look, as everything gets bigger & faster near the bottom of the screen. Without the animation or colours, the entire thing can get as small as 64 char: for(i=z=c.width=300;i--;)x.fillRect(140+T(z^z/i+t*9)*i,90+i,i,1). Feel free to get it even smaller!
