struct FCompressedRichCurve

A runtime optimized representation of a FRichCurve. It consumes less memory and evaluates faster.

Type	Name	Description
TArray< uint8 >	CompressedKeys	Compressed keys, used only outside of the editor
TEnumAsByte< ERichCurveCompressionFormat >	CompressionFormat	Compression format used by CompressedKeys
TConstantValueNumKeys	ConstantValueNumKeys	If the compression format is constant, this is the value returned Inline here to reduce the likelihood of accessing the compressed keys data for the common case of constant/zero/empty curves When a curve is linear/cubic/mixed, the constant float value isn't used and instead we use the number of keys
TEnumAsByte< ERichCurveKeyTimeCompressionFormat >	KeyTimeCompressionFormat	Compression format used to pack the key time
TEnumAsByte< ERichCurveExtrapolation >	PostInfinityExtrap	Post-infinity extrapolation state
TEnumAsByte< ERichCurveExtrapolation >	PreInfinityExtrap	Pre-infinity extrapolation state
