Member Function Documentation

◆ CanFinishImmediately()

bool UE::MovieScene::FSequenceUpdater_Flat::CanFinishImmediately ( TSharedRef< const FSharedPlaybackState > SharedPlaybackState ) const

overridevirtual

Returns whether this instance can be finished immediately without any last update.

Parameters

Linker	The linker that owns this sequence instance
RootInstanceHandle	The handle to the root instance

Returns: Whether the instance can be finished immediately

Implements UE::MovieScene::ISequenceUpdater.

◆ Destroy()

void UE::MovieScene::FSequenceUpdater_Flat::Destroy ( TSharedRef< const FSharedPlaybackState > SharedPlaybackState )

overridevirtual

Called right before this updater's sequence instance is about to be destroyed completely

Parameters

InLinker The linker that is owns this sequence

Implements UE::MovieScene::ISequenceUpdater.

◆ DissectContext()

void UE::MovieScene::FSequenceUpdater_Flat::DissectContext	(	TSharedRef< const FSharedPlaybackState >	SharedPlaybackState,
		const FMovieSceneContext &	InContext,
		TArray< TRange< FFrameTime > > &	OutDissections
	)

overridevirtual

Called before any updates to the sequence to allow this updater to dissect the context into smaller ranges that should be evaluated independently for the purpose of ensuring determinism. If the resulting array is empty the whole context will be used by default.

Parameters

InLinker	The linker that is evaluating this sequence
InPlayer	The movie scene player instance playing this sequence
InContext	The total root-level context for the next evaluation to be dissected
OutDissections	(Out) Array to populate with dissected ranges

Implements UE::MovieScene::ISequenceUpdater.

◆ EvaluateCondition()

bool UE::MovieScene::FSequenceUpdater_Flat::EvaluateCondition	(	const FGuid &	BindingID,
		const FMovieSceneSequenceID &	SequenceID,
		const UMovieSceneCondition *	Condition,
		UObject *	ConditionOwnerObject,
		TSharedRef< const UE::MovieScene::FSharedPlaybackState >	SharedPlaybackState
	)		const

overridevirtual

Implements UE::MovieScene::ISequenceUpdater.

◆ FindSubInstance()

virtual FInstanceHandle UE::MovieScene::FSequenceUpdater_Flat::FindSubInstance ( FMovieSceneSequenceID SubSequenceID ) const

inlineoverridevirtual

Find a sub sequence instance from its ID (if it exists)

Implements UE::MovieScene::ISequenceUpdater.

◆ Finish()

void UE::MovieScene::FSequenceUpdater_Flat::Finish ( TSharedRef< const FSharedPlaybackState > SharedPlaybackState )

overridevirtual

Called before evaluation when this updater's sequence is no longer required to be evaluated

Parameters

InLinker	The linker that is evaluating this sequence
InInstanceHandle	The instance handle for the top level sequence instance that this updater belongs to
InPlayer	The movie scene player instance playing this sequence

Implements UE::MovieScene::ISequenceUpdater.

◆ InvalidateCachedData()

void UE::MovieScene::FSequenceUpdater_Flat::InvalidateCachedData	(	TSharedRef< const FSharedPlaybackState >	SharedPlaybackState,
		ESequenceInstanceInvalidationType	InvalidationType
	)

overridevirtual

Invalidate any cached information that depends on the compiled sequence data due to the compiled data changing

Parameters

InLinker	The linker that is evaluating this sequence
InInstanceHandle	The instance handle for the top level sequence instance that this updater belongs to

Implements UE::MovieScene::ISequenceUpdater.

◆ MigrateToHierarchical()

TUniquePtr< ISequenceUpdater > UE::MovieScene::FSequenceUpdater_Flat::MigrateToHierarchical ( )

overridevirtual

Migrate this updater to one that can represent hierarchical data.

Returns: A new instance capable of dealing with hierarchical data, or nullptr if this already does.

Implements UE::MovieScene::ISequenceUpdater.

◆ OverrideRootSequence()

virtual void UE::MovieScene::FSequenceUpdater_Flat::OverrideRootSequence	(	TSharedRef< const FSharedPlaybackState >	SharedPlaybackState,
		FMovieSceneSequenceID	NewRootOverrideSequenceID
	)

inlineoverridevirtual

Override the sequence ID that should be considered the root sequence for this updater

Parameters

InLinker	The linker that is owns this sequence
InstanceHandle	The instance handle for the root sequence
NewRootOverrideSequenceID	The new sequence ID to treat as the root

Implements UE::MovieScene::ISequenceUpdater.

◆ PopulateUpdateFlags()

void UE::MovieScene::FSequenceUpdater_Flat::PopulateUpdateFlags	(	TSharedRef< const FSharedPlaybackState >	SharedPlaybackState,
		ESequenceInstanceUpdateFlags &	OutUpdateFlags
	)

overridevirtual

Called to initialize the flag structure that denotes what functions need to be called on this updater

Implements UE::MovieScene::ISequenceUpdater.

◆ Start()

void UE::MovieScene::FSequenceUpdater_Flat::Start	(	TSharedRef< const FSharedPlaybackState >	SharedPlaybackState,
		const FMovieSceneContext &	InContext
	)

overridevirtual

Called if this updater has not been evaluated before, or has since been Finished.

Parameters

InLinker	The linker that is evaluating this sequence
InInstanceHandle	The instance handle for the top level sequence instance that this updater belongs to
InPlayer	The movie scene player instance playing this sequence
InContext	The root-level context for the current evaluation.

Implements UE::MovieScene::ISequenceUpdater.

◆ Update()

void UE::MovieScene::FSequenceUpdater_Flat::Update	(	TSharedRef< const FSharedPlaybackState >	SharedPlaybackState,
		const FMovieSceneContext &	InContext
	)

overridevirtual

Called in order that this updater may make any changes to the linker's environment before its sequence is evaluated (ie, initialize or unlink any entity instantiations)

Parameters

InLinker	The linker that is evaluating this sequence
InInstanceHandle	The instance handle for the top level sequence instance that this updater belongs to
InPlayer	The movie scene player instance playing this sequence
InContext	The root-level context for the current evaluation.

Implements UE::MovieScene::ISequenceUpdater.
