Sprite rotation?

Wed, 10 Aug 2016 05:58:45 UTC

My code for sprite rotation:

function sprrot(id,x,y,a,s)
 id=flr(id)
 function getcol(px,py)
  return ((px<1 and py<1)and(px>=0 and py>=0)) and sget((px*8)+((id%16)*8),(py*8)+(flr(id/16)*8)) or -1
 end
 for py=0,s*13 do --floor(9*sqrt(2))
  for px=0,s*13 do
   local uv={x=((px/(11*s))-.6),y=((py/(11*s))-.6)}
   local col=getcol(((uv.x*cos(a))-(uv.y*sin(a)))+.5,((uv.x*sin(a))+(uv.y*cos(a)))+.5)
   if(col>0)then
    pset(flr(x+(px-(6.36*s))),flr(y+(py-(6.36*s))),col)
   end
  end
 end
end

Any better ones?

It's not finished. It has problems with punctuation, quotation marks and some other symbols.
At least it does with numbers and alphabet well.
Move with arrow keys into a character.
If you know how to improve it, please do it.
The algorithm may be inspired from my mosaic image algorithm.

It's my first PICO-8 cartridge uploaded here.
Move with arrow keys and press Z to regenerate.
I've used Prim's algorithm for this. Some common patterns are visible which I don't know how to fix.
This might be buggy, if you're unable to collect all pills please let me know and comment about it because I was a little confused when I coded this.

When I try to play a puzzle, it is just a black screen.
