    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.

Had to make some visual sacrifices to get this #uncompressed
u/pavel

I discovered p+=r*=d(p+=r);q+=s*=d(q+=s) as part of messing around with this. Why does it work?
u/pavel

:)
u/KilledByAPixel

Oh wow, nice! That's the code that updates the position, velocity and applies collision for x and y. It needs to call the d function to check its colliding and also set the block to 1 if it does. It needs to check x and y separately so it knows which side to bounce off
u/pavel

Notice how d only takes one argument, and it ignores it.
u/KilledByAPixel

I see what you did there. So many great tricks in this one.
u/pavel

p+=r*=d(p+=r) the inner p+=r increments p and d ends runs with that value, however the outer p+= caches the old value of p so when d resolves the inner p+=r is silently ignored!
