No need for plugins , you can do it easily without some !
CurX = 0
CurY = -1
Repeat ( num of tiles you want on Y axis )
- add 1 to CurY
- set CurX to 0
-- Repeat ( num of tiles you want on X axis)
--- add 1 to CurX
--- Create Tile at #Xstartingposition#+CurX*(Sizeofatile) , #Ystartingposition#+CurY*(Sizeofatile)
What does this do is loop thru all the possible tiles on the X axis , spawn a tile , go one down and rince and repeat
P.S: Be sure to put the origin of a tile to the top , left
