Functions

Native functions

AddForce

native function AddForce (Object.Vector Force)

AddImpulse

native function AddImpulse (Object.Vector Impulse)

AddTorque

native function AddTorque (Object.Vector Torque)

HasWheelsOnGround

simulated native function bool HasWheelsOnGround ()

HasWheelsOnGround() returns true if any of vehicles wheels are currently in contact with the ground (wheel has bWheelOnGround==true)

InitVehicleRagdoll

native function InitVehicleRagdoll (SkeletalMesh RagdollMesh, PhysicsAsset RagdollPhysAsset, Object.Vector ActorMove, bool bClearAnimTree)

Utility for switching the vehicle from a single body to an articulated ragdoll-like one given a new mesh and physics asset. ActorMove is an extra translation applied to Actor during the transition, which can be useful to avoid ragdoll mesh penetrating into the ground.

IsSleeping

native function bool IsSleeping ()

SetWheelCollision

native final function SetWheelCollision (int WheelNum, bool bCollision)

turns on or off a wheel's collision

Parameters:

• WheelNum - the index of the wheel in the Wheels array to change
• bCollision - whether to turn collision on or off

Events

Destroyed

simulated event Destroyed ()

Overrides: Vehicle.Destroyed

PostBeginPlay

simulated event PostBeginPlay ()

Overrides: Vehicle.PostBeginPlay

Called when gameplay begins. Used to make sure the engine sound audio component has the right properties set to ensure it gets restarted if it has been cut out due to the audio code running out of HW channels to play the sound in.

PostInitAnimTree

simulated event PostInitAnimTree (SkeletalMeshComponent SkelComp)

Overrides: Pawn.PostInitAnimTree

Store pointer to each wheel's SkelControlWheel.

RigidBodyCollision

simulated event RigidBodyCollision (PrimitiveComponent HitComponent, PrimitiveComponent OtherComponent, const out Actor.CollisionImpactData RigidCollisionData, int ContactIndex)

Overrides: Actor.RigidBodyCollision

(Description copied from Actor.RigidBodyCollision)
Called when a PrimitiveComponent this Actor owns has:

   -bNotifyRigidBodyCollision set to true
   -ScriptRigidBodyCollisionThreshold > 0
   -it is involved in a physics collision where the relative velocity exceeds ScriptRigidBodyCollisionThreshold

Parameters:

• HitComponent - the component of this Actor that collided
• OtherComponent - the other component that collided
• RigidCollisionData - information on the collision itslef, including contact points
• ContactIndex - the element in each ContactInfos' ContactVelocity and PhysMaterial arrays that corresponds to this Actor/HitComponent

SuspensionHeavyShift

simulated event SuspensionHeavyShift (float Delta)

called when the suspension moves a large amount, passes the delta

Other instance functions

AddVelocity

function AddVelocity (Object.Vector NewVelocity, Object.Vector HitLocation, class<DamageType> DamageType, optional Actor.TraceHitInfo HitInfo)

Overrides: Pawn.AddVelocity

CalcCamera

simulated function bool CalcCamera (float fDeltaTime, out Object.Vector out_CamLoc, out Object.Rotator out_CamRot, out float out_FOV)

Overrides: Actor.CalcCamera

Calculate camera view point, when viewing this actor.

Parameters:

• fDeltaTime - delta time seconds since last update
• out_CamLoc - Camera Location
• out_CamRot - Camera Rotation
• out_FOV - Field of View

Returns:

true if Pawn should provide the camera point of view.

Died

function bool Died (Controller Killer, class<DamageType> DamageType, Object.Vector HitLocation)

Overrides: Vehicle.Died

(Description copied from Pawn.Died)
This pawn has died.

Parameters:

• Killer - Who killed this pawn
• DamageType - What killed it
• HitLocation - Where did the hit occur

Returns:

true if allowed

DisplayDebug

simulated function DisplayDebug (HUD HUD, out float out_YL, out float out_YPos)

Overrides: Vehicle.DisplayDebug

(Description copied from Vehicle.DisplayDebug)

See: Actor::DisplayDebug

DisplayWheelsDebug

simulated function DisplayWheelsDebug (HUD HUD, float YL)

Special debug information for the wheels that is displayed at each wheel's location

DrivingStatusChanged

simulated function DrivingStatusChanged ()

Overrides: Vehicle.DrivingStatusChanged

GetDefaultCameraMode

simulated function name GetDefaultCameraMode (PlayerController RequestedBy)

Overrides: Vehicle.GetDefaultCameraMode

(Description copied from Pawn.GetDefaultCameraMode)
returns default camera mode when viewing this pawn. Mainly called when controller possesses this pawn.

Parameters:

• PlayerController - requesting the default camera view

Returns:

default camera view player should use when controlling this pawn.

GetSVehicleDebug

simulated function GetSVehicleDebug (out array<string> DebugInfo)

Retrieves important SVehicle debug information as an array of strings. That can then be dumped or displayed on HUD.

HermiteEval

simulated function float HermiteEval (float Slip)

Hermite spline evaluation for use with the slip curve debug display

PostTeleport

function PostTeleport (Teleporter OutTeleporter)

Overrides: Actor.PostTeleport

SetAllWheelParticleSystem
