I'm wondering whether its possible to render a terrain via a mysql database.
I plan to have the table looking like, (x,y->,z1,z2,z3,z4[sections of each tile])

x,y = tile by tile
z1 -> z4 = Height.

If i have a tile with four corners, then each would be assigned z1 -> z4,
_____
|z1---|z2 ...

True, lol, i did google google,and found nothing, hats why i asked

XD, i googled a*, as a string or math function fo working out tiles lol, thanks

How would i go about having a mesh, and each square representing a coordinant?

and when a play clicks:EG, Player1 is on 1,1(coords) and wants to move to 2,4(coords) it finds the quickest path, and then moves off.
