Functions

  Type Name Description
Public function FTransform

CalculateRelativeBoneTransform ( const FName ToBoneName,
const FName FromBoneName,
const FReferenceSkeleton& ReferenceSkeleton
)

 Returns the 'To' bone's transform relative to the 'From' bone.
Public function    
Public function int32

FillInlineShapeArray_AssumesLocked ( PhysicsInterfaceTypes::FInlineShapeArray& Array,
const FPhysicsActorHandle& Actor
)

  
Public function uint32 Generates a hash value in accordance with the uint64 implementation of GetTypeHash which is required for backward compatibility as older versions of UPhysicsAssetInstance stored a TMap.
