ConstructObject<>() Deprecated?

Hi, I have some trouble updating my project to 4.8 : I have some “ConstructObject is deprecated” in my compilation, and it say to use NewObject() instead.

I find it really weird since I’m using ConstructObject because it what everyone say to use instead of NewObject, and I have no idea how to use NewObject to match my actual code :

UStaticMeshComponent* comp = ConstructObject<UStaticMeshComponent>(UStaticMeshComponent::StaticClass(), this, *node->GetAttribute("name"));
comp->SetStaticMesh(Cast<UStaticMesh>(StaticLoadObject(UStaticMesh::StaticClass(), NULL, TEXT("/Engine/EngineMeshes/Cube.Cube"))));
comp->AttachTo(GetRootComponent(), NAME_None, EAttachLocation::KeepWorldPosition);

(this) reference a class that extends AActor()

Thanks for any help!

Hello, megatlantis

This change was made in order to simplify UObject creation.
With NewObject, your code will look something like this:

UStaticMeshComponent* comp = NewNamedObject<UStaticMeshComponent>(this, *node->GetAttribute("name"));

Hope this helped!

Have a great day!

Thanks you, it’s working fine with this !

ConstructObject<> does provide you with more options, but you’re right, there is a compiler warning that suggests it is deprecated.

return NewObject(InParent, Class, Name, Flags);

I think NewNamedObject is deprecated now too in favor of NewObject

It isn’t. Here is how you use it: Objects in Unreal Engine | Unreal Engine 5.0 Documentation
