Since patch 2 matrix tiles are now referenced in a very odd order, after preparing a matrix texture the top row of tiles are acessed in numerical order then the bottom, then 1 up from the bottom and so on...
ie.
01 02 03 04
13 14 15 16
09 10 11 12
05 06 07 08
This next one may have been in from the beginning but i'm not sure. Dimensioned arrays sometimes return a 0 when called from within another dimensioned array, however I have not assertained the particular circumstances under which this occurs.
eg: print map(playerX(player),playerZ(player))
computes as: print map(0,0)
