static const FTransform & GetComponentSpaceTransformWithCache
(
const FReferenceSkeleton & InRefSkeleton,
const TArray< FTransform > & InBoneSpaceTransforms,
int32 BoneIndex,
TArray< FTransform > & CachedTransforms,
TArray< bool > & CachedTransformReady
)
Calculate the component-space bone transform for the specified bone. This is similar to GetComponentSpaceTransform(), but uses a cached array of transforms to prevent re-calculations when requesting transforms for multiple bones with shared parents. This is only likely to be more efficient than FillUpComponentSpaceTransforms if you only need a relatively small number of bone transforms.

Parameter |
Description |
|---|---|
|
InRefSkeleton |
The bone hierarchy |
|
InBoneSpaceTransforms |
Bone-space transforms for all bones in the hierarchy |
|
BoneIndex |
We calculate the component-space transform of this bone |
|
CachedTransforms |
An array of transforms which holds the transforms of any bones whose transforms have been previously calculated. Should be initialized with CachedTransforms.SetNumUninitialized(BoneSpaceTransforms.Num()) before first use. |
|
CachedTransformReady |
An array of flags indicating which bone transforms have been cached. Should be initialized with CachedTransformReady.SetNumZeroed(BoneSpaceTransforms.Num()) before first use. |
