Yeah - something like pokemon - people collect random creatures and pit them against each other, and some way to combine them

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; }
u/danny@hille.dk

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" :-)
