Factorio Forums

Thanks to https://www.reddit.com/r/factorio/comme ... y_operate/ I have just learned that I need to be checking for ghost belts and splitters and undergrounds in my "does this real belt curve" code. That means I need to know whether a ghost underground belt is an input or an output. I started writing this request for LuaEntity.ghost_belt_to_ground_type but then discovered the new(ish) Linked Belt entity and the docs saying that LuaEntity.linked_belt_type works directly on ghosts. So I tried LuaEntity.belt_to_ground_type on a ghost... and it works!

So, this request is just to note that in the docs, like it's noted for linked_belt_type, e.g. "Can also be used on entity ghost if it contains linked-belt."

PS: While we're at it, LuaEntity.ghost_loader_type probably deserves this treatment as well.

PPS: It would be great if this was a json field, not just description text. Like `subclasses`, but this field might be called something like `ghost_passthrough`?

PPPS: I started writing this in the interface request forum when I thought it would require an interface change. I guess this is just a doc request now. I'd appreciate if a forum mod would move this over there.

As stated at the top of the page most functions of LuaEntity work on ghosts. So we're unlikely to note this on every single thing.

It seems like just a few more recent additions (belt_shape and all the linked_belt fields and methods) got a comment in the description like "Can also be used on entity ghost if it contains [some subclass]". The presence of those feels misleading and is what suggested to me that it didn't apply to some others similar fields. Would it be possible to remove those, for consistency? I suspect some new dev thought, as I did, that this was less reliable/universal than it is.
