    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.

i think like this for(i=69,h=0;a=47+43*S(i/6+t),i--;h+=a) could be more accurate

75byte #physics

u/tomxor

Perfect collision integration, since uniform gravity is constant it should cancel out in such a simple case, in which case integration can be skipped on a collision interval ?-b:b+.3 this is why it doesn't loose or gain significant hight on average
u/tomxor

To make it absolutely perfect this can also be changed to ?-b:b+.25 which will eliminate integration error since .25 is a non periodic binary fraction... it will bounce forever :)
u/tomxor

... but that would cost an extra byte so its no good !
