示例1: GetSceneComponents
void UActorRecording::GetSceneComponents(TArray<USceneComponent*>& OutArray, bool bIncludeNonCDO/*=true*/)
{
// it is not enough to just go through the owned components array here
// we need to traverse the scene component hierarchy as well, as some components may be
// owned by other actors (e.g. for pooling) and some may not be part of the hierarchy
if(GetActorToRecord() != nullptr)
{
USceneComponent* RootComponent = GetActorToRecord()->GetRootComponent();
if(RootComponent)
{
// note: GetChildrenComponents clears array!
RootComponent->GetChildrenComponents(true, OutArray);
OutArray.Add(RootComponent);
}
// add owned components that are *not* part of the hierarchy
TInlineComponentArray<USceneComponent*> OwnedComponents(GetActorToRecord());
for(USceneComponent* OwnedComponent : OwnedComponents)
{
check(OwnedComponent);
if(OwnedComponent->GetAttachParent() == nullptr && OwnedComponent != RootComponent)
{
OutArray.Add(OwnedComponent);
