Anybody know what the size is for tilesets and sprites?

Asking for a freind.

there is no size - there is only format and structure.

for tilesets, check the help file.
There are six different formats for tilesheets, five formats used for A1 to A5 each and the sixth format for B-E. You can only use a tilesheet in the slot it is formatted for, and each format is a different combination of tiles in different sizes, from 32x32 pixel regular tile to 192x96 pixel animated autotile.

for sprites, there is no size. each spritesheet consists of either 3x4 or 12x8 cells that all have to have the same size, but any cell size is possible. the base default cell size would be 32x32 for Ace, but any size goes as long as all cells are the same size

The tiles work on a 32x32 pixel grid. Standard sprites are the same, though really can be any size if formatted correctly.

Thanks :D!
