This is a tileset borrowed from Reiners Tilesets, and I will use it as an example..
The width and height of the tileset are 96 x 96. There are 3 x 3 tiles in this tileset... 3 rows and 3 columns. This means each tile is 32 pixels by 32 pixels..
This means you should set the tile width and height to 32 x 32..
Now, for horizontal offset and vertical offset, this is just for fancy tilesets. This is used when the top-left tile isnt in the very top-left corner, but is some distance away. You use the offsets to position the little green boxes over the first tile, and then you use the H and V seperations..
H sep and V sep are the distance in between tiles. In the example above, each tile is packed up very close, with no spaces in between, the other tiles. This means both of these values need to be 0. But, say each tile had a 1 pixel thin border, then you now need 1 H sep and 1 V sep, to seperate the tiles a small amount.
Play around, it's the best way to learn.
Thanks guys! I got it perfectly!!!!!!!!!
