Syntax
struct FCompressedRichCurve
Remarks
A runtime optimized representation of a FRichCurve. It consumes less memory and evaluates faster.
Variables
| 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 |
