## 判断骨骼格式

|
|
```c++
|
|||
|
|
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;
|
|||
|
|
}
