    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.

I'm not sure how this is supposed to work... See for example d/9677 -- your tool gives "eval(unescape(escape𒡦𫱲𚁩👣𛡷𪑤𭁨𧠽𜀻𪐭𛐻𮀮𨡥𩱩𫡐𨑴𪀨𮀮𩡩𫁬𚀩𚐩𠰨𨐽𭀭𪐩🠰𙠦𮀮𩑬𫁩𬁳𩐨𞐶𜀫𚁘🐨𪐪𞐶𜀭𪐪𪐩𚠪𛠵𚡓𚁡𚐩𛀶𜀫𪐬𚁳🐲𝐭𚁓𚁡𛐱𚐪𚁢🐨𜐭𚀨𦐽𪐭𝀸𜀩𛰴𞀰𚐪𚠲𚐪𚠮𝐩𚐪𚠴𚠲𝀩𚡃𚁡𚐪𨠬𬰬𣑡𭁨𛡡𭁡𫠨𦐯𦀩𛀰𛀷𚐻.replace(/u../g,'')))" which is 225B

This is on Firefox 64.0, 64-bit, on Ubuntu. This may require a browser that counts characters differently?
u/metamero

just paste the compressed code on new dweet, it works. to remix you have to delete disabled atribute of post button on inspector. this is a #bug on dwitter page's char counting, but server counts right (number of unicode glyphs <= 140) so posting astral unicode chars works fine. there is this discussion on github... but the status now is at least inconsistent.
u/f8f82804

could you point me to that github discussion?
u/f8f82804

ahhhh yeah i see what you mean about inconsistent -- the new dweet shows 225/140 but still allows it to be posted, while the remix button is disabled with the same code
u/f8f82804

personally, I thought that this was intentional, and that the char counting was counting 16-bit char codes, not unicode code points (e.g. the difference between charCodeAt and codePointAt)

this doesnt like code like thsi: x.fillText('⬛⬜' ( I get a short output with an unterminated string constant errro on the dweet, but it finishes comprssing with code like this x.fillText(['⬛','⬜'] Which takes me up to a 140B output, yet doesnt run, Aggh, Im so close...

!! before entering the canvas with the cursor, #fullscreen! It simulates quadratic gravity, not the Newtonian one! only 119 bytes, my own gravity system, inspired from u/metamero 's projects! There is no infinite velocity bug so the rectangle will not disappear so fast. If you have entered the canvas and you didn't fullscreen, reset the project by adding inoffensive changes to the script, then fullscreen. #interactive #physics #gravity

now correct #gravity formula : #orbit #physics #interactive : click to set atractor : double click to reset
