    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.

Down to 99, to make room for clouds at both ends

u/richev

I'm very much a beginner here, and am still running out of characters :-) x.font="450px'";x.fillText('☁️ ☁️',90,1080)
u/stiaje

Instead of 1080, you can write 2e3 which is short for 2000.
u/stiaje

Or 1e3, I guess :)
u/stiaje

Also, because the dweet starts with with(x) you don't need to write x.fillText, just fillText, as long as you make sure to separate your statements with a comma instead of a semicolon!

Ha! Nice. 😀
u/micahcowan

Your use of ... '5em 🅓🅦🅘🅣🅣🅔🅡' to automagically limit it to one character, blew my damn mind. Is that your innovation, or did you get it from another? The useless JS things I learn here 😁
u/micahcowan

Wait, I'm amazed it even works, since those are each two chars in UTF-16. I thought JS deals in UTF-16, not -32? Is string subscripting more magical than I supposed? Time to go fishing through Ecma-262...
u/firegodjr

He's turning it into an array first, so the individual chars still act individually, and not as two UTF-16 chars. Array[x] works, String[x] only supports UTF-16.
u/micahcowan

Awesome, thanks. Had just figured that out when I refreshed the page to see if someone said that, heh!
u/micahcowan

You can see what's happening more clearly if you change 2e3 to 5e2. It's also interesting to set n=8, but then you also want to change 🅓🅦🅘🅣🅣🅔🅡 to 🅡🅓🅦🅘🅣🅣🅔
u/magna

@micahcowan It's a culmination of 1) spread syntax 2) using bullshit strings as font names that I've learned from others :)

You could use clipping to have the pointing hand disappear into the OK hand if you placed the clip rectangle just right. I don't know how you would save up the characters though, maybe by using a for loop to only have one fillText call (but that would also eat characters with all the ?: statements you'd have instead).
u/magna

Yeah, clipping would make it awesome! Let's see if this can be golfed down significantly to open up space for some clipping.
u/Agnes

I posted a clipping remix. You can do scaling, translation and rotation in a single call to setTransform.
