If true, attach the driver to the vehicle when he starts using it.

Default value: True

bAvoidReversing

used by AI to know that controller's rotation determines vehicle rotation

bHasHandbrake

Type: bool

hint for AI

bRetryPathfindingWithDriver

steering value used last tick

OldThrottle

Type: float

Functions

Native functions

GetTargetLocation

simulated native function Object.Vector GetTargetLocation (optional Actor RequestedBy, optional bool bRequestAlternateLoc) const

Overrides: Actor.GetTargetLocation

Returns:

Figure out who we are targetting.

Native implementation:

FVector AVehicle::GetTargetLocation(AActor *RequestedBy, UBOOL bRequestAlternateLoc) const
{
        if ( Mesh )
        {
                return Mesh->LocalToWorld.GetOrigin() + TargetLocationAdjustment;
        }
        return CylinderComponent->LocalToWorld.GetOrigin() + TargetLocationAdjustment;
}

Events

ContinueOnFoot

event bool ContinueOnFoot ()

ContinueOnFoot() - used by AI Called from route finding if route can only be continued on foot. Returns true if driver left vehicle

Destroyed

simulated event Destroyed ()

Overrides: Pawn.Destroyed

DriverLeave

event bool DriverLeave (bool bForceLeave)

Called from the Controller when player wants to get out.

EncroachedBy

event EncroachedBy (Actor Other)

Overrides: Pawn.EncroachedBy

Vehicles dont get telefragged.

EncroachingOn

event bool EncroachingOn (Actor Other)

Overrides: Pawn.EncroachingOn

called when this Actor is encroaching on Other and we couldn't find an appropriate place to push Other to

Returns:

true to abort the move, false to allow it

Warning: do not abort moves of PHYS_RigidBody actors as that will cause the Unreal location and physics engine location to mismatch

PostBeginPlay

event PostBeginPlay ()

Overrides: Pawn.PostBeginPlay

ReplicatedEvent

simulated event ReplicatedEvent (name VarName)

Overrides: Pawn.ReplicatedEvent

TakeDamage

event TakeDamage (int Damage, Controller EventInstigator, Object.Vector HitLocation, Object.Vector Momentum, class<DamageType> DamageType, optional Actor.TraceHitInfo HitInfo, optional Actor DamageCauser)

Overrides: Pawn.TakeDamage

(Description copied from Actor.TakeDamage)
apply some amount of damage to this actor

Parameters:

• Damage - the base damage to apply
• EventInstigator - the Controller responsible for the damage
• HitLocation - world location where the hit occurred
• Momentum - force caused by this hit
• DamageType - class describing the damage that was done
• HitInfo - additional info about where the hit occurred
• DamageCauser - the Actor that directly caused the damage (i.e. the Projectile that exploded, the Weapon that fired, etc)
