判断骨骼格式

bool FSkeletonMatcher::IsMatching(const USkeleton* Skeleton) const  
{  
    // No Skeleton, No matching...  
    if (Skeleton == nullptr)  
    {       return false;  
    }  
    const int32 NumExpectedBones = BoneNames.Num();  
    int32 nMatchingBones = 0;  
    const FReferenceSkeleton & SkeletonRefSkeleton = Skeleton->GetReferenceSkeleton();  
    for (int32 i = 0; i < NumExpectedBones; ++i)  
    {       const int32 BoneIndex = SkeletonRefSkeleton.FindBoneIndex(BoneNames[i]);  
       if (BoneIndex != INDEX_NONE)  
       {          ++nMatchingBones;  
       }    }    const float MatchedPercentage = float(nMatchingBones) / float(NumExpectedBones);  
  
    return MatchedPercentage >= MinimumMatchingPerc;  
}
