Syntax

class UAnimStreamable : public UAnimSequenceBase

Variables

	Name	Description
TArray< FName >	AnimationTrackNames	This is name of RawAnimationData tracks for editoronly - if we lose skeleton, we'll need relink them
bool	bEnableRootMotion	If this is on, it will allow extracting of root motion
bool	bForceRootLock	Force Root Bone Lock even if Root Motion is not enabled
UAnimBoneCompre...	BoneCompressionSettings	The bone compression settings used to compress bones in this sequence.
bool	bUseNormalizedRootMotionScale	If this is on, it will use a normalized scale value for the root motion extracted: FVector
UAnimCurveCompr...	CurveCompressionSettings	The curve compression settings used to compress curves in this sequence.
EAnimInterpolat...	Interpolation	This defines how values between keys are calculated
int32	NumFrames	Number of raw frames in this sequence (not used by engine - just for informational purposes).
TArray< struct ...	RawAnimationData	Raw uncompressed keyframe data.
FGuid	RawDataGuid
FName	RetargetSource	Base pose to use when retargeting
TEnumAsByte< ER...	RootMotionRootLock	Root Bone will be locked to that position when extracting root motion.
FStreamableAnim...	RunningAnimPlatformData
const UAnimSequ...	SourceSequence	Sequence the streamable was created from (used for reflecting changes to the source in editor)
TMap< const ITa...	StreamableAnimPlatformData	Editor can have multiple platforms loaded at once.
TArray< struct ...	TrackToSkeletonMapTable	In the future, maybe keeping RawAnimSequenceTrack + TrackMap as one would be good idea to avoid inconsistent array size TrackToSkeletonMapTable(i) should contains track mapping data for RawAnimationData(i).

Overridden from UObject

	Name	Description
void	FinishDestroy()	Called to finish destroying the object.
void	GetResourceSizeEx ( FResourceSizeEx& CumulativeResourc... )	Get the size of the object/resource for use in memory tools or to display to artists/LDs in the Editor This is the extended version which separates up the used memory into different memory regions (the actual definition of which may be platform specific).
void	PostLoad()	Do any object-specific cleanup required immediately after loading an object.
void	PreSave ( const ITargetPlatform* TargetP... )	Presave function.
void	Serialize ( FArchive& Ar )	Handles reading, writing, and reference collecting using FArchive.
