I don't need to test my programs. I have an error-correcting modem.

Internal variables[edit]
AccumLODDistanceCheckTime[edit]
Type: float
Modifiers: transient
LOD updating...
AccumTickTime[edit]
Type: float
Modifiers: transient
Used to accumulate total tick time to determine whether system can be skipped ticking if not visible.
bDeferredBeamUpdate[edit]
Type: bool
Set this to TRUE to have beam emitters defer their update until the data is being passed to the render thread.
bForcedInActive[edit]
Type: bool
Modifiers: transient
This is set when any of our "don't tick me" timeout values have fired
bIsActive[edit]
Type: bool
Modifiers: transient
INTERNAL Set to TRUE when InitParticles has been called. Set to FALSE when ResetParticles has been called. Used to quick-out of Tick and Render calls (when caching PSysComps and emitter instances).
bIsCachedInPool[edit]
Type: bool
bCanBeCachedInPool
If this is true, when the PSC completes it will do the following:
bHidden = TRUE
This is used for Particles which are cached in a pool where you need to make certain to NOT kill off the EmitterInstances so we do not re allocate.
See: ActivateSystem() where it rewinds the indiv emitters if they need it
bIsViewRelevanceDirty[edit]
Type: bool
Modifiers: transient
If TRUE, the ViewRelevanceFlags are dirty and should be recached
bIsWarmingUp[edit]
Type: bool
Modifiers: transient
This is set when the particle system component is warming up
bJustAttached[edit]
Type: bool
Indicates that the component has not been ticked since being attached.
bLODUpdatePending[edit]
Type: bool
Modifiers: transient
bRecacheViewRelevance[edit]
Type: bool
Modifiers: transient
If TRUE, the VRF were updated and should be passed to the proxy.
bSkipSpawnCountCheck[edit]
Type: bool
Modifiers: transient
Check the spawn count and govern if needed
bSkipUpdateDynamicDataDuringTick[edit]
Type: bool
Flag indicating that dynamic updating of render data should NOT occur during Tick. This is used primarily to allow for warming up and simulated effects to a certain state.
bSuppressSpawning[edit]
Type: bool
Modifiers: const
bUpdateComponentInTick[edit]
Type: bool
Set this to TRUE to have the PSysComponent update during the tick if 'dirty'.
bUpdateOnDedicatedServer[edit]
Type: bool
whether to update the particle system on dedicated servers
bWarmingUp[edit]
Type: bool
bWasCompleted[edit]
Type: bool
Modifiers: const
bWasDeactivated[edit]
Type: bool
Modifiers: const
CachedViewRelevanceFlags[edit]
Type: array<PrimitiveComponent.MaterialViewRelevance>
Modifiers: transient, const
The view relevance flags for each LODLevel.
CollisionEvents[edit]
Type: array<ParticleEventCollideData>
Modifiers: transient
The Collision events that occurred in this PSysComp.
DeathEvents[edit]
Type: array<ParticleEventDeathData>
Modifiers: transient
The Death events that occurred in this PSysComp.
EditorLODLevel[edit]
Type: int
INTERNAL. Used by the editor to set the LODLevel
EmitterDelay[edit]
Type: float
Modifiers: transient
This is created at start up and then added to each emitter
EmitterInstances[edit]
Type: array<pointer{struct FParticleEmitterInstance}>
Modifiers: native, transient, const
KismetEvents[edit]
Type: array<ParticleEventKismetData>
Modifiers: transient
The Kismet events that occurred for this PSysComp.
LightEnvironmentClass[edit]
Type: class<ParticleLightEnvironmentComponent>
Class of the light environment that will get created for lit particle systems.
Default value: Class'Engine.ParticleLightEnvironmentComponent'
LODLevel[edit]
Type: int
MaxTimeBeforeForceUpdateTransform[edit]
Type: float
Time between forced UpdateTransforms for systems that use dynamically calculated bounds, Which is effectively how often the bounds are shrunk.
Default value: 5.0
OldPosition[edit]
Type: Object.Vector
PartSysVelocity[edit]
Type: Object.Vector
ReleaseResourcesFence[edit]
Type: pointer{class FRenderCommandFence}
Modifiers: const, native, transient
Command fence used to shut down properly
ReplayClipIDNumber[edit]
Type: int
Modifiers: transient, const
Clip ID number we're either playing back or capturing to, depending on the value of ReplayState.
ReplayFrameIndex[edit]
Type: int
Modifiers: transient, const
The current replay frame for playback
ReplayState[edit]
Type: ParticleReplayState
Modifiers: transient, const
Current particle 'replay state'. This setting controls whether we're currently simulating/rendering particles normally, or whether we should capture or playback particle replay data instead.
SMComponents[edit]
Type: array<StaticMeshComponent>
Modifiers: private, transient, duplicatetransient, const
The static mesh components for a mesh emitter. This is to prevent the SMCs from being garbage collected.
SMMaterialInterfaces[edit]
Type: array<MaterialInterface>
Modifiers: private, transient, duplicatetransient, const
SpawnEvents[edit]
Type: array<ParticleEventSpawnData>
Modifiers: transient
The Spawn events that occurred in this PSysComp.
TimeSinceLastForceUpdateTransform[edit]
Type: float
Modifiers: private, transient
Tracks the time since the last forced UpdateTransform.
ViewMBInfoArray[edit]
Type: array<ViewParticleEmitterInstanceMotionBlurInfo>
Modifiers: const, native, transient
Emitter instance motion blur info stored per view
WarmupTime[edit]
Type: float
