Classes

  Type Name Description
Public struct UStruct FCompressedRichCurve A runtime optimized representation of a FRichCurve.  
Public struct UStruct FCurveAtlasColorAdjustments    
Public struct FCurveAttributes Structure allowing external curve data to express extended attributes  
Public class FCurveOwnerInterface Interface you implement if you want the CurveEditor to be able to edit curves on you.  
Public struct UStruct FIndexedCurve A curve base class which enables key handles to index lookups.  
Public struct UStruct FIntegralCurve An integral curve, which holds the key time and the key value  
Public struct UStruct FIntegralKey An integral key, which holds the key time and the key value  
Public struct FKeyHandle Key handles are used to keep a handle to a key. They are completely transient.  
Public struct UStruct FKeyHandleLookupTable Lookup table that maps key handles to indices in an external data structure Maintains a map of key handle to last known index, and an array of optional key handles that's used to validate map entries.  
Public struct UStruct FKeyHandleMap Represents a mapping of key handles to key index that may be serialized  
Public struct UStruct FNameCurve Implements a curve of FNames.  
Public struct UStruct FNameCurveKey One key in a curve of FNames.  
Public struct UStruct FRealCurve A rich, editable float curve  
Public struct UStruct FRichCurve A rich, editable float curve

Public struct UStruct FSimpleCurveKey One key in a rich, editable float curve  
Public struct UStruct FStringCurve Implements a curve of FStrings.  
Public struct UStruct FStringCurveKey One key in a curve of FStrings.  
Public class IKeyFrameManipulator Templated key frame manipulator that knows how to add, remove and (re)arrange key times.  
Public class TKeyFrameManipulator Templated key frame manipulator that knows how to add, remove and (re)arrange key times.  
Public struct TKeyTimeIterator Key time iterator for TKeyFrameManipulator  
Public class UClass Abstract, MinimalAPI BlueprintType UCurveBase Copyright Epic Games, Inc.  
Public class UClass MinimalAPI BlueprintType UCurveFloat    
Public class UClass MinimalAPI BlueprintType HideCategories collapsecategories UCurveLinearColor    
Public class UClass MinimalAPI UCurveLinearColorAtlas Manages gradient LUT textures for registered actors and assigns them to the corresponding materials on the actor  
Public class UClass MinimalAPI BlueprintType UCurveVector    
Public class UClass deprecated UDEPRECATED_CurveEdPresetCurve CurveEdPresetCurve A preset curve data object

Typedefs

Name Description
FOnUpdateGradient Delegate called right before rendering each slot. This allows the gradient to be modified dynamically per slot.
FRichCurveEditInfo Rename and deprecate.
FRichCurveEditInfoConst  

Enums

  Type Name Description
Public enum UEnum ERichCurveCompressionFormat Enumerates curve compression options.  
Public enum UEnum BlueprintType ERichCurveExtrapolation Enumerates extrapolation options.  
Public enum UEnum BlueprintType ERichCurveInterpMode Method of interpolation between this key and the next.  
Public enum UEnum ERichCurveKeyTimeCompressionFormat Enumerates key time compression options.  
Public enum UEnum BlueprintType ERichCurveTangentMode If using RCIM_Cubic, this enum describes how the tangents should be controlled in editor.  
Public enum UEnum BlueprintType ERichCurveTangentWeightMode Enumerates tangent weight modes.  

Functions

  Type Name Description
Public function CurveValueType

UE::Curves::BezierInterp ( CurveValueType P0,
CurveValueType P1,
CurveValueType P2,
CurveValueType P3,
float Alpha
)

 Assuming that P0, P1, P2 and P3 are sequential control points of an N=4 Bezier curve, returns the interpolated value for interpolation constant Alpha in [0, 1]
