CollectionSphere->GetOverlappingActors(CollectedActors); // 收集所有与SphereComponent碰撞的actor
for (int32 iCollected = 0; iCollected < CollectedActors.Num(); ++iCollected)
{
APickUp const TestPickup = Cast<APickUp>(CollectedActors[iCollected]);
if (TestPickup && !TestPickup->IsPendingKill() && TestPickup->IsActive()) //判断如果该物体是PickUp并且没有被杀死 并且处于激活状态
{
TestPickup->WasCollected();
TestPickup->SetActive(false);
}

}
