    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.

6.3 is pretty much 2*PI. Putting fill() where it is causes it to fill the pacman in 9 times but saves a byte. Using with saves another 1-2 bytes.

#FFEE00 is also supposedly the official Pacman colour.
u/silver_bear

Wow, you're quite a bit more advanced than me. Very nice! :)
u/lionleaf

Cool! Similar to one of the really old dweets by u/iverjo : d/312 . :)
u/21medals

you can save 2 bytes by moving "w=500" to the moveTo()
u/AnnanFay

You can also replace 2*w+w*i+++t*-w%w with 2*w+w*i++-t*w%w for 1 byte, you can save 2 bytes by adding i=2 and w*i++-t*w%w which puts us at 135 bytes
u/AnnanFay

One thing I'd like to fix is the rate which pac-man bites down at. It would be nice if it synchronised with the squares.

Building an infinite maze.

u/aleamb

I did not have space for Math.random, so i have used the decimals from t variable multiplying by 1e8 and then extract one variable bit for true/false condition. Thus it is not true random

Better said, it is worst than Math.random

This is a template to play with drop-in replacements for Math.random(). Enter code in the last line that uses the existing variables to produce values in the range [0,1). Red squares will appear if values are out of range.
