最近想写一个类似鬼泣 收集红魂的功能，陆续写点东西作为笔记

  // set up a notification for when this component overlaps something  
    CollisionSphere->OnComponentBeginOverlap.AddDynamic(this, &ALightSwitchCodeOnly::OnOverlapBegin);  


void ALightSwitchCodeOnly::OnOverlapBegin(class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)  
{  
    // Other Actor is the actor that triggered the event. Check that is not ourself.  
    if ( (OtherActor != nullptr ) && (OtherActor != this) && ( OtherComp != nullptr ) )  
    {  
        // Turn off the light  
        PointLight->SetVisibility(false);  
    }  
}
