it says -
it's possible to define multiple different requirement vectors for units and buildings, one of which must evaluate to true to be able to build the unit/building.
Is this possible now with 2.6? What would that look like? I'd like to use one for an [extra_canal] in terrain.ruleset. The wiki page -
only says -
obsolete_by vectors from buildings.ruleset that have "or" logical operation
Does the wiki need updating?
