Flag: Factory
File(s): rules(md).ini
Values: Strings: Normal text. (Limited to: hardcoded values (see article))
Default: <none>
Applicable to: BuildingTypes

This tag determines what type of object a BuildingType produces. Although it accepts any string from the list, only four of them will actually work after going through a filtering routine:

  • AircraftType
  • BuildingType
  • InfantryType
  • UnitType

Allowed values


This value indicates that this building can manufacture AircraftTypes. It is not required for this structure to double as an aircraft docking structure.


This value indicates that this building can manufacture other BuildingTypes.


This value indicates that this building can manufacture InfantryTypes. ExitCoord is not obeyed, and actual exit coords are controlled by the GDIBarracks, NODBarracks and YuriBarracks flags.


This value indicates that this building can manufacture ground vehicles (with Naval=no) or naval ships (with Naval=yes). Mind that a ground vehicle factory without WeaponsFactory=yes will have certain side-effects.

Be aware that all vehicles associated with this factory MUST specifically list this factory in its Prerequisite list, or there is a possibility that you will be faced with the NCO Bug.

Internal meaning

This section is in need of revision.

Internally, the value of Factory is used to determine what something is. If - for instance - a pointer to a TechnoType (by origin) is given over to a function, the function could get the TechnoType's "Factory" and determine whether it's a Building or an Infantry, Unit or Aircraft.
This works using an RTTI ID number for every Factory.

Although VesselType as well as CloningType are sometimes mentioned in Rules(md).ini, they are not valid values.
