Functions

Static functions

DrawKillIcon

simulated static function DrawKillIcon (Canvas Canvas, float ScreenX, float ScreenY, float HUDScaleX, float HUDScaleY)

Exec functions

EditUDmgFX

exec function EditUDmgFX (optional int Index)

FixedView

exec function FixedView (string VisibleMeshes)

Native functions

ApplyMorphDamage

native function ApplyMorphDamage (Object.Vector HitLocation, int Damage, Object.Vector Momentum)

When damage occur, we need to apply it to any MorphTargets. We do this natively for speed

Parameters:

• HitLocation - Where did the hit occured
• Damage - How much damage occured

ForceWeaponRotation

native simulated function ForceWeaponRotation (int SeatIndex, Object.Rotator NewRotation)

GetAlternateLockTarget

native function Actor GetAlternateLockTarget ()

Returns:

Actor that can be locked on to by weapons as if it were this vehicle

GetBarrelIndex

native simulated function int GetBarrelIndex (int SeatIndex)

GetSeatPivotPoint

native simulated function Object.Vector GetSeatPivotPoint (int SeatIndex)

GetTeamNum

simulated native function byte GetTeamNum ()

Overrides: Pawn.GetTeamNum

Returns:

the TeamIndex of this vehicle

InitDamageSkel

native simulated function InitDamageSkel ()

InUseableRange

simulated native function bool InUseableRange (UTPlayerController PC, float Dist)

IsSeatControllerReplicationViewer

native(999) noexport final function bool IsSeatControllerReplicationViewer (int SeatIndex)

Returns:

whether we are currently replicating to the Controller of the given seat this would be equivalent to checking bNetOwner on that seat, but bNetOwner is only valid during that Actor's replication, not during the base vehicle's not complex logic, but since it's for use in vehicle replication statements, the faster the better

NativePostRenderFor

simulated native function NativePostRenderFor (PlayerController PC, Canvas Canvas, Object.Vector CameraPosition, Object.Vector CameraDir)

Overrides: Actor.NativePostRenderFor

Hook to allow actors to render HUD overlays for themselves. Assumes that appropriate font has already been set

native simulated function byte SeatFiringMode (int SeatIndex, optional byte NewFireMode, optional bool bReadValue)

SeatFlashCount

native simulated function byte SeatFlashCount (int SeatIndex, optional byte NewCount, optional bool bReadValue)

SeatFlashLocation

native simulated function Object.Vector SeatFlashLocation (int SeatIndex, optional Object.Vector NewLoc, optional bool bReadValue)

SeatWeaponRotation

native simulated function Object.Rotator SeatWeaponRotation (int SeatIndex, optional Object.Rotator NewRot, optional bool bReadValue)

SetHUDLocation

simulated native function SetHUDLocation (Object.Vector NewHUDLocation)

Overrides: Actor.SetHUDLocation

function used to update where icon for this actor should be rendered on the HUD

Parameters:

• NewHUDLocation - is a vector whose X and Y components are the X and Y components of this actor's icon's 2D position on the HUD

SetMaxRadius

native function SetMaxRadius (SoundNodeAttenuation Node)

Hack the max radius to be updated values

UpdateDamageMaterial

native simulated function UpdateDamageMaterial ()

Whenever the morph system adjusts a health, it should call UpdateDamageMaterial() so that any associated skins can be adjusted. This is also native

VehicleHudCoordsFixup

native function VehicleHudCoordsFixup ()
