Building Commands

Just like UNITs, BUILDINGs can execute commands, as specified in Table .

Table: Commands available to BUILDINGs.

Command	Recur	Length	Target	Description
Produce	yes	Tbl	adjacent CELLs	Produce one FRU of the RESOURCE for the CELL occupied by the BUILDING and for every adjacent cell. Note: The Produce event should be scheduled separately for each affected cell.
Defend	yes	instant	none	Defend the BUILDING from attacks. In addition, while Defending, the BUILDING adds its defense value to the defense values of any UNITs in any adjacent CELLs.
Attack	yes	8	UNIT or BUILDING	Attack a UNIT or BUILDING within a radius of 2 CELLs of this BUILDING.

The properties of BUILDING COMMANDs are the same as for UNIT COMMANDs (Section ). Like UNIT COMMANDs, the UI MUST offer a way to select BUILDINGs, targets, and COMMANDS, and must prevent the player from executing illegal COMMANDS.
