UnrealGame

SpecialVehicleObjectives are used to mark the end of special paths that a vehicle is required to reach, but have something a vehicle cannot get (like a pickup). Bots will only consider following one of these paths if it is enabled and the bot is controlling a vehicle of one the allowed classes. When they reach this point, they will exit the vehicle and continue to the associated actor on foot.

To get an idea of possible uses, have a look at ONS-Torlan: There's a SpecialVehicleObjective on the tower because the Redeemer (and Super Shield Pack) up there can only be reached using a Raptor.

Usage

Due to the way (un)triggering and resetting affects SpecialVehicleObjectives, there doesn't seem to be any use for them other than telling bots how to reach pickups.

If you have a super pickup that can't (or shouldn't) be reached on foot, e.g. because it's up high, place a SpecialVehicleObjective near the pickup. Match the pickup's Tag and the SpecialVehicleObjective's AssociatedActorTag to specify the destination object. Also match the pickup's Event and the SpecialVehicleObjective's Tag to properly enable the SpecialVehicleObjective when the pickup is available.
