    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.

SPACE INVADERS

u/Polyducks

Weird... I wonder why it's stopped working...
u/magna

It still works for me. macOS + Chrome.
u/joeytwiddle

MacOS and Chrome here. The unicode char (was it 👾?) appears to get stripped while loading. If I paste it in between the "", then it works. Perhaps Dwitter loads differently on different pages?

That's a really clever illusion, love it
u/magna

Heh, thanks! Brought it down to 123 chars in hopes of adding occasional mistakes like skipped characters / typos etc., but couldn't immediately find a way. In case anyone wants to give it a shot: https://www.dwitter.net/d/2522
u/donbright

u/Polyducks

Could you make a random function to skip odd spaces?
u/magna

It has to be a deterministic PRNG so that the places that are skipped are persistent. Otherwise, it would just look like a random flipping of characters. I thought about it, but couldn't immediately find a short solution.
u/Polyducks

That's a great point. Dwitter is such a mind twister!

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

I'm going to revision :D

Lock some of the blocks, so not everything is moving at once: s=i+2*C(t/4+i)**32

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.
