KVehicle

UT2004 :: Actor >> Pawn >> Vehicle >> KVehicle (Package: Engine)

The K in KVehicle stands for Karma, and this class is controlled by some native Karma functions. The KVehicle extends Vehicle, which extends Pawn, and so gets a lot of stuff from Pawn, like Health.

See KVehicle (UT2003) for the UT2003 version of this class.

See SVehicle for the base class of vehicles used in UT2004.

Constants

FilterFrames = 5: The length of the CameraHistory array. (see Other Properties below)

Properties

KVehicle Group

bool bAutoDrive: If set to True, the steering is set to 1 and the Throttle to 0.4 when there is no driver
class<Actor> DestroyEffectClass: The class of the effect that is spawned when the vehicle is destroyed

Other Properties

bool bHistoryWarmup: The history isn't filled
bool bVehicleIsFiring: If is True then the driver wants to fire
bool bVehicleIsAltFiring: If is True then the driver wants to altfire
vector CameraHistory[FilterFrames]: Keeps track of the last few camera look-at positions in order to smooth them in SpecialCalcView.
int NextHistorySlot: The next slot that has to be filled with in the camera history

Methods

Inherited From Actor

Destroyed() (simulated): Vehicle is destroyed, remove attached stuff, create effect, set factory vehicle count -1 (if any)
TakeDamage( int Damage, Pawn instigatedBy, vector hitlocation, vector momentum, class<DamageType> damageType ): Only calls super class implementation.
Tick( float deltaSeconds ) (simulated): Overridden with no code.

Inherited From Pawn

bool SpecialCalcView( out Actor ViewActor, out vector CameraLocation, out rotator CameraRotation ) (simulated): When bSpecialCalcView is True, this function is called to set the position of the camera. Uses CameraHistory to smooth look-at position over a few frames.

Inherited From Vehicle

ClientKDriverEnter( PlayerController PC ) (simulated, replicated to client): Driver enters, called also on clients, mainly sets HUD
ClientKDriverLeave( PlayerController PC ) (simulated, replicated to client): Driver leaves, called also on clients, mainly resets HUD
KDriverEnter( Pawn P ): Driver enters, sets the controller to the vehicle, and attaches the pawn to the car
bool KDriverLeave( bool bForceLeave ): Driver leaves, The driver exits at the 1st possible exit pos (not blocked) and the controller is attached to it.
TryToDrive( Pawn P ): Called when someone tries to get in

New Functions

GraphData( string DataName, float DataValue ) (native, final): "Useful function for plotting data to real-time graph on screen."
KVehicleUpdateParams() (simulated): Used to update the vehicles Para on all the attached actors (like wheels)
VehicleStateReceived(): An event, called when a new state is received, implemented in subclass : (comment says in VehicleState, but KVehicle doesn't have a VehicleState (Given that this is an event called from native code, and the superclass of KVehicle has nativereplication, it seems likely that VehicleState is a native struct.))
