    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.

Cookie clicker! Click for cookies, press space for clickers (each one costs 50 more than the last)

Show more comments…
u/KilledByAPixel

awesome! i was confused at first, you need to click 50 times before you can click space to buy an auto clicker.
u/katkip

Awesome!
u/lionleaf

Awesome! Pressing space scrolls the page down though :(
u/lionleaf

I've spent way too much time on the original cookie-clicker... I'd also recommend the paperclips game

u/mildlybean

I love the paperclips game
u/katkip

tycoons are boring and fun in the same time
u/lionleaf

I got to 600M cookies and now have 7k clickers. Turns out at some point it starts becoming possible to go negative as well. Currently at -130M #cookie #cookie_clicker

You have 2 characters left. You can use those to cover any number overflows :P

change f(x) and d (difference)

u/katkip

f=x=>S(x/9)+C(x/9);d=81 is nice
u/katkip

lol that is actually equivalent to f=x=>S(x/9)*2;d=81
