Member Data Documentation

◆ BoneIndex

int32 FFABRIKChainLink::BoneIndex

Bone Index in SkeletalMesh

◆ ChildZeroLengthTransformIndices

TArray<int32> FFABRIKChainLink::ChildZeroLengthTransformIndices

Child bones which are overlapping this bone. They have a zero length distance, so they will inherit this bone's transformation.

◆ DefaultDirToParent

FVector FFABRIKChainLink::DefaultDirToParent

Default Direction to Parent

◆ Length

double FFABRIKChainLink::Length

Distance to its parent link.

◆ Position

FVector FFABRIKChainLink::Position

Position of bone in component space.

◆ TransformIndex

int32 FFABRIKChainLink::TransformIndex

Transform Index that this control will output
