Adding new menu options to node editor

[Swing Wren]

Hi, I'm trying to add more options to the node Editor to make iterations faster for our game.

I managed to do the change required by modifying the DialogueEditorWindowConversationNodeEditor.cs file and adding a empty method so I can get an error if an update overrides my changes.

Code: Select all

           ....
	   AddCustomOptionsFromExternalProject(contextMenu, entry);

            AddCanvasContextMenuGotoItems(contextMenu);

            contextMenu.AddSeparator(string.Empty);
            contextMenu.AddItem(new GUIContent("Play From Here..."), false, PlayConversationFromEntry, currentEntry.id);

            contextMenu.ShowAsContext();
            contextMenuPosition = Event.current.mousePosition;

            EditorZoomArea.Begin(_zoom, _zoomArea);
        }
        
          private const string InterrogationActionId = "InterrogationActionId";
        private const string InterrogationPressValue = "0";
        private const string CustomFieldType_InterrogationActionId = "CustomFieldType_InterrogationActionId";

        private void AddCustomOptionsFromExternalProject(GenericMenu contextMenu, DialogueEntry entry) {
            contextMenu.AddSeparator(string.Empty);
            
            void MarkAsInterrogationPress(object o) {
                DialogueEntry entryToMark = o as DialogueEntry;
                if (entryToMark == null) {
                    return;
                }
                Field foundField = null;
                foreach (Field field in entry.fields) {
                    if (field.title != InterrogationActionId) {
                        continue;
                    }
                    foundField = field;
                    break;
                }
                if (foundField != null) {
                    foundField.value = "0";
                    return;
                }
                entry.fields.Add(new Field(InterrogationActionId, InterrogationPressValue, FieldType.Number, CustomFieldType_InterrogationActionId));
            }
            
            contextMenu.AddItem(new GUIContent("Mark as Interrogation Press Node"), false, MarkAsInterrogationPress, entry);
            contextMenu.AddSeparator(string.Empty);
        }
        
                
        public static void EnsureCustomChangesAreThere() {
            
        }

My question is: Is there a cleaner way to achieve what I'm trying to do or any recommendation for custom changes?
(I discarded the idea of adding the field in a template as I don't want for each node to have a field that is not used often)

Hi,

Can you use the C# hooks (see Customizing the Editor) instead of directly modifying the Dialogue System's source code?

[Swing Wren]

I was not aware of those hooks, sadly are not in the places I need. (I want to add them to the context menu of a dialogue entry node). But that is much better for modifying the source code, I'll just add more hooks to the DialogueEditorWindowDelegates file

thanks!

[Tony Li]

Let me know what you'll add, and I'll add the same to the original Dialogue System files so you won't lose your customizations when you update.

Sorry for the huge delay,

I only ended up doing this:

Code: Select all

   contextMenu.AddSeparator(string.Empty);
   contextMenu.AddItem(new GUIContent("Play From Here..."), false, PlayConversationFromEntry, currentEntry.id);

   if (customSetupDialogueEntryNodeContextMenu != null) customSetupDialogueEntryNodeContextMenu(contextMenu,entry);
            
   contextMenu.ShowAsContext();
   contextMenuPosition = Event.current.mousePosition;

Either way I don't mind doing the changes every time, I already have a few modifications on the dialogue system and one more is no trouble

I've just added a similar hook to version 2.2.48:

customNodeContextMenuSetup(DialogueDatabase database, DialogueEntry entry, GenericMenu contextMenu)

When you update to 2.2.48+, you can use this delegate instead of directly modifying DialogueEditorWindowConversationNodeEditor.cs.
