Detailed Description

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

Member Data Documentation

CompressedKeys

TArray<uint8> FCompressedRichCurve::CompressedKeys

Compressed keys, used only outside of the editor

CompressionFormat

TEnumAsByte<ERichCurveCompressionFormat> FCompressedRichCurve::CompressionFormat

Compression format used by CompressedKeys

ConstantValueNumKeys

TConstantValueNumKeys FCompressedRichCurve::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

KeyTimeCompressionFormat

TEnumAsByte<ERichCurveKeyTimeCompressionFormat> FCompressedRichCurve::KeyTimeCompressionFormat

Compression format used to pack the key time

PostInfinityExtrap

TEnumAsByte<ERichCurveExtrapolation> FCompressedRichCurve::PostInfinityExtrap

Post-infinity extrapolation state

PreInfinityExtrap

TEnumAsByte<ERichCurveExtrapolation> FCompressedRichCurve::PreInfinityExtrap

Pre-infinity extrapolation state
