I’ve noticed other stuff in the files that is not mentioned in that link. For instance, the multitiles function.
I tried to do a top down tileset but I soon noticed it wouldn’t work coz there’s no way to rotate sprites in order for them to make sense. Like making sinks, toilets and similar furniture face a certain direction depending on the wall they are next to.
Multitiles can be used with doors and windows but when they are destroyed, the direction they are facing resets to default so that doesn’t work either.
