Instance functions

ActivateEventClass

simulated final function bool ActivateEventClass (class<SequenceEvent> InClass, Actor InInstigator, const out array<SequenceEvent> EventList, optional const out array<int> ActivateIndices, optional bool bTest, optional out array<SequenceEvent> ActivatedEvents)

Iterates through the given list of events and looks for all matching events, activating them as found.

Returns:

true if an event was found and activated

ApplyFluidSurfaceImpact

simulated function ApplyFluidSurfaceImpact (FluidSurfaceActor Fluid, Object.Vector HitLocation)

Called when this actor touches a fluid surface

CalcCamera

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

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 Actor should provide the camera point of view.

CanActorPlayFaceFXAnim

simulated function bool CanActorPlayFaceFXAnim ()

Returns FALSE if Actor can play facefx Implement in sub-class.

CanSplash

simulated function bool CanSplash ()


CheckForErrors

function bool CheckForErrors ()


CheckHitInfo

final simulated function CheckHitInfo (out TraceHitInfo HitInfo, PrimitiveComponent FallBackComponent, Object.Vector Dir, out Object.Vector out_HitLocation)

Make sure we pass along a valid HitInfo struct for damage. The main reason behind this is that SkeletalMeshes do require a BoneName to receive and process an impulse... So if we don't have access to it (through touch() or for any non trace damage results), we need to perform an extra trace call().

Parameters:

  • HitInfo - initial structure to check
  • FallBackComponent - PrimitiveComponent to use if HitInfo.HitComponent is none
  • Dir - Direction to use if a Trace needs to be performed to find BoneName on skeletalmesh. Trace from HitLocation.
  • out_HitLocation - HitLocation to use for potential Trace, will get updated by Trace.

CheckMaxEffectDistance

simulated function bool CheckMaxEffectDistance (PlayerController P, Object.Vector SpawnLocation, optional float CullDistance)


ClearLatentAction

simulated final function ClearLatentAction (class<SeqAct_Latent> actionClass, optional bool bAborted, optional SeqAct_Latent exceptionAction)

Clears all latent actions of the specified class.

Parameters:

  • actionClass - type of latent action to clear
  • bAborted - was this latent action aborted?
  • exceptionAction - action to skip

DisplayDebug

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

list important Actor variables on canvas. HUD will call DisplayDebug() on the current ViewTarget when the ShowDebug exec is used

Parameters:

  • HUD - HUD with canvas to draw on
  • out_YL - Height of the current font
  • out_YPos - Y position on Canvas. out_YPos += out_YL, gives position to draw text for next debug line.

DoKismetAttachment

function DoKismetAttachment (Actor Attachment, SeqAct_AttachToActor Action)

Performs actual attachment. Can be subclassed for class specific behaviors.

  • out_EventList - list of found events
  • bIncludeDisabled - will not filter out the events with bEnabled = FALSE

Returns:

true if any events were found

Take Radius Damage by default scales damage based on distance from HurtOrigin to Actor's location. This can be overridden by the actor receiving the damage for special conditions (see KAsset.uc). This then calls TakeDamage() to go through the same damage pipeline.

Parameters:

  • InstigatedBy - instigator of the damage
  • BaseDamage -
  • DamageRadius - from Origin)
  • DamageType - class
  • Momentum - float)
  • HurtOrigin - origin of the damage radius.
  • bFullDamage - if true, damage not scaled based on distance HurtOrigin
  • DamageCauser - the Actor that directly caused the damage (i.e. the Projectile that exploded, the Weapon that fired, etc)
  • DamageFalloff - allows for nonlinear damage falloff from the point. Default is linera.

Returns:

Returns amount of damage applied.

TriggerGlobalEventClass

simulated function bool TriggerGlobalEventClass (class<SequenceEvent> InEventClass, Actor InInstigator, optional int ActivateIndex)

trigger a "global" Kismet event (one that doesn't have an Originator, generally because it's triggered by a game-time object)

Returns:

true to indicate this actor was activated

VolumeBasedDestroy
