    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.

Woodmouth's ant chasing your mouse

Show more comments…
u/joeytwiddle

Since I couldn't fit the edge detection, I stop the ant when it reaches the target. So I stored the target in k,j
u/donbright

this mouse technique is excellent
u/joeytwiddle

To make him a slow turner: D=(Math.atan2(j-b,k-a)-d+3.14)%6.24-3.14;d+=.05*D
u/joeytwiddle

err I mean 6.28
u/Woodmouth

That's impressive. The slow turn was exactly what i was looking for, but that is sadly just a bit too big.
u/MrM@_S

K=3.14;d+=((Math.atan2(j-b,k-a)-d+K)%6.28-K)/20

Thanks to @donbright who showed me where i could save 5 chars
u/iverjo

Very impressive :D
u/donbright

this is unbelievable. (ps thx but i stole the idea from others here)
u/donbright

(ok technically they gave it to me prob @cantelope / @manga)
u/Woodmouth

This is the strangest piano i've ever played, but good job!
u/Woodmouth

Also, i found a way to stop it, just press shift. (or any other key with a value too high or low to hear (At least i think that's what happens))

Check the old comments for some simple tunes to play. You'll need to click on the blank canvas for keyboard focus. Hit Space, Shift or Escape for "silence".

Unfortunately I am too far from the party. BTW this dweet runs too quickly. I should have used t/3

Can you arrange the numbers vertically? Feel free to use the special moves!

u/Woodmouth

It's not a space limitation issue, it's a feature!
u/donbright

absolutley brilliant however e.x/e.y dont seem to work in firefox
u/joeytwiddle

Thanks don. I golfed this over a 24 hour period, but could not squeeze a better "valid move" rule in. Remixes welcome!
u/donbright

firefox should adopt e.x and e.y just so your dweet work
u/joeytwiddle

Hehe. Sadly the mouse coords are also problematic in fullscreen, and on mobile.
u/joeytwiddle

Valid moves are -4,-1,+1,+4. I have found a "valid move" test: **2|17)^17|| Will post the remix sometime.

Starts making noise if you click on the canvas. Hopefully you can silence it by going left, but no guarantees!

u/cantelope

"woooOOOOoooOOOO" :D

It's a dweetheremin!
u/joeytwiddle

Yes it is :) More fun with a wider frequency range: o.start());c.onmousemove=e=>o.frequency.value=5*e.x

Haha, amazing! Fullscreen gives you a wider audio range :)
