class sc2.unit.Unit(proto_data, bot_object, distance_calculation_index=-1, base_build=-1)
property add_on_land_position: Point2

If this unit is an addon (techlab, reactor), returns the position where a terran building (BARRACKS, FACTORY, STARPORT) has to land to connect to this addon.

Why offset (-2.5, 0.5)? See description in ‘add_on_position’

property add_on_position: Point2

If this unit is a terran production building (BARRACKS, FACTORY, STARPORT), this property returns the position of where the addon should be, if it should build one or has one attached.
