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 was trawling the interwebs for fun and leisure and found this sprite sheet http://legacy.gamebuino.com/forum/viewtopic.… and of course i thought of dwitter :-)

    wow amazing encoding
  • u/danny@hille.dk
    Thanks mate, I didn't really know how the encoding was done, so i came up with this solution function makeMagicString(data, width){ let buf = ''; let str = '' data.forEach((o,i)=>{ if(i%width===0 && i){ str += String.fromCharCode(parseInt(buf,2)); buf = ''; } buf += o?1:0; }) str += String.fromCharCode(parseInt(buf,2)) return str; }

    where data is an array of 1 and 0 ex: [0,0,0,0,0,1,1,1,1,1,0,0,0,0,0, 0,0,0,1,1,1,0,0,0,1,1,1,0,0,0, 0,0,1,1,1,1,0,0,0,0,1,1,1,0,0, 0,1,1,1,1,0,0,1,1,1,0,1,1,1,0, 0,1,0,0,0,0,1,1,1,1,1,0,1,1,0, 1,0,1,1,0,0,0,1,1,1,0,0,0,0,1, 1,1,1,1,1,0,0,0,0,0,0,0,0,1,1, 1,0,1,1,0,0,0,0,0,0,0,0,1,1,1, 1,0,0,0,1,1,1,1,1,1,1,0,0,1,1, 0,1,1,1,0,0,1,0,1,0,0,1,1,1,0, 0,0,1,0,0,0,1,0,1,0,0,0,1,0,0, 0,0,0,1,0,0,0,0,0,0,0,1,0,0,0, 0,0,0,0,1,1,1,1,1,1,1,0,0,0,0]

    I know it's not the most elegant solution, but I stick to the mantra "If it works, it aint stupid" :-)
