Hi Guys, thanks for the responses The fact that the script works for left but not right is what's killing me. Add to that, once left is clicked then right works perfectly. So although for some reason I have what might be a NAN index, it resolves itself once the second (identical function) is called. This implies to me a difference between cell[posX+1] and cell[posX-1] , in that one is a NAN the other isn't.
I was kinda hoping that someone would pop up and go of course [x-1] is different to [x+1]!!!! Anyways I like the idea of leaner meaner json and can easily adapt so that to go right used to be x+1 and down was y+1 : cell[x][y] becomes (in a single dimensioned) right equals x+1 and down is x+8. :cell[0-63] I'm not convinced it will help since I still need to be able to lookahead to the adjoining cells : if cell[x+8]=0 but the fact that it is not multidimensional might make it easier to solve. I'll post my results if you are interested thanks Rob On Wed, Feb 29, 2012 at 12:38 AM, rasmusfl0e <[email protected]> wrote: > Hmmm, maybe I'm missing something - but sometimes your for-loops run to 8 > and sometimes to 7... is that on purpose.
