Name Remarks Include Path Unreal Specifiers

static double CalculateMagnitude ( const FVector& Vector,
EMotionExtractor_Axis Axis
)

 Helper function to calculate the magnitude of a vector only considering a specific axis or axes MotionExtractorUtilities.h  

static FTransform ExtractBoneTransform ( UAnimSequence* Animation,
const FBoneContainer& BoneContainer,
FCompactPoseBoneIndex CompactPoseBoneIndex,
float Time,
bool bComponentSpace
)

 Helper function to extract the pose for a given bone at a given time IMPORTANT: This function expects you to add a MemMark (FMemMark Mark(FMemStack::Get());) at the correct scope if you are using it from outside world's tick MotionExtractorUtilities.h  

static FName GenerateCurveName ( FName BoneName,
EMotionExtractor_MotionType MotionType,
EMotionExtractor_Axis Axis
)

 Generates a curve name based on input settings. MotionExtractorUtilities.h
