Ahh I see, thanks for the explanation! I'm new to the whole JSON stuff so I don't fully understand it yet but I think I managed to figure out how to get the room width thanks to your explanation - I would just like your input on if the following is a decent enough way to go about it?
var json = scrPackedRoom00() packedRoomWidth = ds_map_find_value(ds_map_find_value(json,"roomSettings"),"Width")
