How to retrieve ALL components?

[Amerio.Stephane]

Hi, is there a easy or preferred way to retrieve all components or all node with a type of component? Even if this is slow.

The alternative would be to store all components at creation time, but there may already exist an easier way to do that?

Hello! 

template <class T>
void collectAllComponents(Unigine::Vector<T *> &out_components)
{
	Unigine::Vector<Unigine::NodePtr> root_nodes;
	Unigine::World::getRootNodes(root_nodes);
	for (auto & it : root_nodes)
		Unigine::ComponentSystem::get()->getComponentsInChildren<T>(it, out_components, false);
}

// usage example
Unigine::Vector<MyComponent *> components;
collectAllComponents(components);
