Why would this function crash my project? could it be something in settings or this function?

// gets total KG of things on plate
float UDoorOpenClose::GetTotalMassOfActorOnPlate()

float TotalMass = 0.0f;

// finds all overlapping actors
TArray<AActor*> OverlappingActors;
TriggerVolume->GetOverlappingActors(OUT OverlappingActors);

// Iterate through them add their mass

	TotalMass += Actor->FindComponentByClass<UPrimitiveComponent>()->GetMass();

}

return TotalMass;
}

when you use const auto* Actor

auto gets AAcotr* which is dereferenced because of auto* and then -> operator becomes ambiguous

see this for reference

Iterating over TArray with for

The lecture presents the following code as preventing changes to Actor: for (const auto& Actor : OverlappingActors) { // Use Actor } This isn’t the case, since auto is deduced to be AActor* and const will apply to the outermost type (that is deduced by auto), or the pointer in this case. This means that the type of Actor is Actor* const& and Visual Studio will show this in a tooltip when hovering over Actor. The corresponding code to make Actor const, would be: for (const auto* Actor : Ov…
