Enumeration Type Documentation

◆ EInterpCurveMode

enum EInterpCurveMode

Enumerator
CIM_Linear	A straight line between two keypoint values.
CIM_CurveAuto	A cubic-hermite curve between two keypoints, using Arrive/Leave tangents. These tangents will be automatically updated when points are moved, etc. Tangents are unclamped and will plateau at curve start and end points.
CIM_Constant	The out value is held constant until the next key, then will jump to that value.
CIM_CurveUser	A smooth curve just like CIM_Curve, but tangents are not automatically updated so you can have manual control over them (eg. in Curve Editor).
CIM_CurveBreak	A curve like CIM_Curve, but the arrive and leave tangents are not forced to be the same, so you can create a 'corner' at this key.
CIM_CurveAutoClamped	A cubic-hermite curve between two keypoints, using Arrive/Leave tangents. These tangents will be automatically updated when points are moved, etc. Tangents are clamped and will plateau at curve start and end points.
CIM_Unknown	Invalid or unknown curve type.
