I'm making a character whose top and bottom need to move independently once they're in game. The top moves to aim and shoot while the bottom runs in whatever direction the player wants. I'm going to be importing into Gamemaker and I'm new to Spriter. Is it possible to have both parts in the same project or would I need to do separate ones? I'm just an artist, so I really have no idea. I just want to have everything exported in a correct and efficient way for a buddy who offered to help program.
