I mean there are a lots of feature is locked behid dlc feature flags but documentation seems not actually explain what mapped to what,only said it require space age.
For example what feature key is agriculture tower catgorized in? spoiling? how about plantprototype ?
fusion-reactor prototype?
is more Planet categorized in space_travel ? etc...
in a way https://lua-api.factorio.com/latest/aux ... cture.html do explain something but not much...

Re: Detail of feature flags
If my memory serves me right yes, its just not been done yet afaik. You obviously can't rely on the space-age graphics for your own fusion prototypes then.
Re: Detail of feature flags
Actually you can, even if the space-age mod is disabled, you can actuallly use __base__/../space-age to load their graphics.BrainGamer_ wrote: Wed Oct 15, 2025 6:38 pmIf my memory serves me right yes, its just not been done yet afaik.

No, you can't rely upon it.

Re: Detail of feature flags

Re: Detail of feature flags
Answer: No, because helpers.is_valid_sprite_path("__base__/../space-age/thumbnail.png") is not usable in prototype stage.
and even it does, you probablly cannot use it for detection purpose at all.

Re: Detail of feature flags
To be fair, being able to do that's a sandbox violation and should be fixed (or made properly a feature).meifray wrote: Sun Oct 19, 2025 5:42 pm Answer: No, because helpers.is_valid_sprite_path("__base__/../space-age/thumbnail.png") is not usable in prototype stage.
