Better Way to Deduce Object Type ?

Development Programming & Scripting C++

Hi guys, I’m working on a plugin code to be running in editor.

I want to know what type of object is selected. Options are : PointLight,
RectLight,
SpotLight,
DirectionalLight,
SkyLight

One way to do is casting object, but I think there should be a smarter way of it.
Any one has any idea ?

My code is:


AActor* selectedActor = GEditor->GetSelectedActors()->GetTop<AActor>();

APointLight* PointLightActor = Cast<APointLight>(selectedActor);


if (PointLightActor != nullptr)
{
UE_LOG(LogTemp, Warning, TEXT("Found Point Light Actor !"));
}

If I get 1 actor from GetSelectedActors function , what could be best way to know which class this object is from , apart from trying casting

Casting is too expensive.

Try “IsA()”:



if ( selectedActor->IsA( APointLight::StaticClass() )
{
    //
}

Correct Sir! I didn’t thought about it.
