[Solved] Custom editor: Graph with edges

Hi,
The title is self-explanatory, I´m trying to create a custom editor for a graph in the scene view as in the following image:




The logic behind the directed graph is quite intuitive for me But when it comes to the implementation of the custom editor, I am lost.
The idea is to be able to spawn nodes (this is already done) , right click on them to create an edge and then move the mouse and right click on the destination of that edge to set it.


With the following code I am drawing the nodes:

Code (CSharp):

1.  
2.     [DrawGizmo(GizmoType.Selected | GizmoType.NotInSelectionHierarchy)]
3.     static void DrawGizmos(Path path, GizmoType gizmoType)
4.     {
5.         foreach (Node node in path.Nodes)
6.         {
7.             Gizmos.color = Color.red;
8.             Gizmos.DrawSphere(node.transform.position, 1);
9.            
10.             Gizmos.color = Color.blue;
11.             foreach (Edge edge in node.Edges)
12.                 Gizmos.DrawLine(node.transform.position, edge.to.transform.position);
13.         }
14.     }

The nodes are empty GameObjects + Node component, and therefore they are not clickable or raycastable.
If I draw the nodes using OnDrawGizmos() in their class, they can be selected on the scene view but I do not know how to get this event, whereas with the upper code they cannot be selected. How can I raycast/click/select a node with code?

Any input is welcome

 

I guess I could get the closest node to my right click as long as it is within x distance. Or is there another way?

 

Above solution works perfectly. Writing the question made me realise how easy the solution was. ^^
