c++, how would I update the objects in this?

void Scene::insertGameObject(std::unique_ptr& object)

{

_gameObjects.push_back(std::move(object));

}

void Scene::Update(double deltaTime)

{

// TODO: update objects in the scene

}

void Scene::Draw(ID2D1HwndRenderTarget & target)

{

for (auto& object : _gameObjects)

{

const auto& renderer = object->getRenderer();

renderer.Render(target, object->getLocation());

}

}
