Can this be used for autotile in gms2?
It can be used with anything that can use tilesets. But I think you're more specifically asking if it has variations for all 47 autotile options? If so, that answer is no, this tileset only have middle + inner corners + outer corners + and vertical/horizontal edges (13 in total).
There are tool that can convert to 47-tile tilesets, but I haven't tried so you would need to do some research on this.
I hope that answers the question, thanks!
