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[edit]
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.
Properties[edit]
Property group 'SpecialVehicleObjective'[edit]
AccessibleVehicleClasses[edit]
Classes of vehicles that are capable of reaching this point.
AssociatedActorTag[edit]
Type: name

If greater than 0, bots will never go here unless they are already this close
Internal variables[edit]
AssociatedActor[edit]
Type: Actor
The actor this special vehicle objective belongs to. (Set in PostBeginPlay.)
bEnabled[edit]
Type: bool
Whether this SpecialVehicleObjective is currently reachable. Disabled on Trigger and Reset, enabled on Untrigger if there's an AssociatedActor.
NextSpecialVehicleObjective[edit]
Type: SpecialVehicleObjective
The next item in the linked list of SpecialVehicleObjective, which starts with UnrealMPGameInfo.SpecialVehicleObjectives.
TeamOwner[edit]
Type: Pawn
Array size: 4
AI pawns currently headed to this point
Default values[edit]
| Property | Value |
|---|---|
| bNotBased | True |

Untrigger[edit]
Overrides: Actor.UnTrigger
Enables this SpecialVehicleObjective, but only if its AssociatedActor is set.
Other instance functions[edit]
