OK, next question: Is there a way to specifically limit a component or facility so that only 1 is effective? Like spaceyards, excepts using requirements/abilities/etc instead of being hardcoded in the game?
Edit: Never mind - I figured it out.
Code:
Number Of Requirements := 2
Requirements Evaluation Availability := AND
Requirements Evaluation Allows Placement := 1
Requirements Evaluation Allows Usage := 2
Requirement 1 Description := Empire must have at least tech level 1 in Resupply.
Requirement 1 Formula := Get_Empire_Tech_Level("Resupply") >= 1 + (([%Level%] - 1) * 4)
Requirement 2 Description := This vehicle can only have one emergency resupply component on it.
Requirement 2 Formula := Get_Design_Ability_Component_Count("Emergency Resupply") = 0
