            Vector2 rectOffset = new Vector2(200, 0);
            DialogueNode newNode = CreateInstance<DialogueNode>();
            newNode.name = Guid.NewGuid().ToString();
            Undo.RegisterCreatedObjectUndo(newNode, "Created Dialogue Node");
            if (parent != null)
            {
                parent.children.Add(newNode.name);
                newNode.rect.position = parent.rect.position + rectOffset;
            }
            nodes.Add(newNode);
            OnValidate();
        }```

If you want to have new spawned nodes to spawn to the right of the parent you can get the parent position and add an offset like the above.

Good tip!

I’ve made it a bit different, but about the same :sweat_smile:

newNode.rect.position = new Vector2(parent.rect.position.x + parent.rect.width + 50, parent.rect.position.y);

Also I’ve used 50 'cause it’s the same value of the background grid… but I didn’t want to access to the constant on the DialogueEditor.cs

[Edit]
Extended the code to avoid overlapping if children are already present, for example you create a new from Node1 when Node1 already have a child

if(parent.GetChildren().Count > 1)
            {
                newNode.SetPosition(new Vector2(parent.GetRect().position.x + parent.GetRect().width + 75, parent.GetRect().position.y + 75));
                AddNode(newNode);
            }
            else
            {
                newNode.SetPosition(new Vector2(parent.GetRect().position.x + parent.GetRect().width + 50, parent.GetRect().position.y));
                AddNode(newNode);
            }
