Seeking the knowledge and wisdom of Kaimetsu's tile script ability

[T-Squad]

im a n00b to changing tiles and such, then i look at your script and im like......*long silence*.......*mass confusion*.......and i cant figure it out...basicly, do the tile on graal have some mathematical relationship with each other, allowing people to easily change the tiles..? cause i sure dont know....bah if you dont reply im probably gonna find a way myself, but its alot easier this way...the only tile stuff i know is:
board[int(x)+64*int(y)] = tilex+tiley*16;
updateboard x,y,width,height;

yes, if you want to find 546768738496 measurements for tiles you can do it that way, but if you are smart (like me) you will sek the knowledge of Kai
