Creating custom nodes in the editor

[karim.salama]

Hi,

I'm currently porting a custom tool from the old editor (deprecated) to the new one.

In this tool there is a feature which added a node to the world using the following UnigineScript code :

Creator::set_node(node,"editor/gui/node_reference.png");

What is the equivalent in C++ for the new editor?

Thanks

Hello,

Please look at this C++ code, it's some equivalent for Creator::set_node:

#include <editor/Actions.h>
#include <editor/Selection.h>
#include <editor/Selector.h>

void add_node_dummy()
{
	NodeDummyPtr node = NodeDummy::create();

	// By using Undo::begin() and Undo::end() it's possible to group actions. For example, create and select a new node at once.
	Editor::Undo::begin();
	Editor::Undo::apply(new Editor::CreateNodesAction(node));
	// Ask Editor to select a new created node.
	Editor::SelectionAction::applySelection(Editor::SelectorNodes::createObjectsSelector({ node }));
	Editor::Undo::commit();
}

Ok thanks, I will try this.

By the way, I couldn't find the CreateNodesAction in the current documentation : https://developer.unigine.com/en/docs/2.14.1/api/editor/class_editor_1_1_action.html

Hi Karim, 

Please check out the new version of docs:

https://developer.unigine.com/en/docs/future/api/editor/class_editor_1_1_create_nodes_action.html

There is no CreateNodesAction action in 2.14.1.1, it is only available starting from 2.15.

Thanks!

@victor Ok, this works. But is the node gets added to the world directly.

Is there anyway I can wait for the user to place the newly created node in the world, or press esc to cancel?

@fox Ok, I will take a look. And yes I am using 2.15-beta.

Thanks

Could you please tell how it was done in your pervious plugin implementation?

@silent It was done using the following UnigineScript code :

#include <editor/editor.h>
Creator::set_node(node,"editor/gui/node_reference.png");

I guess it's not possible right now in 2.15-beta, but it would be very nice to have this in the 2.15 release.

Yes, it will be possible. It's some code snippet:

#include <editor/ViewportManager.h>

NodeDummyPtr dummy = NodeDummy::create();
::Editor::ViewportManager::placeNodes({dummy});
