Help Wanted Dynamically change ValueOutput node type based on ValueInput type

Hello,

I am playing around with custom nodes and was wondering if there was a way to change my output based on the input, and have it update in the graph view.

I do realize there are already InputSystem nodes built in, but humor me as I will probably want to do this in the future.

example:


^I would like the output node to change to a "bool" value in this case.

I was also wondering if there is a proper method for updating the node if something changes in the node?

Code (CSharp):

1. protected override string hookName =>
2.             InputSystem.settings.updateMode ==
3.             InputSettings.UpdateMode.ProcessEventsInDynamicUpdate
4.             ? EventHooks.Update
5.             : EventHooks.FixedUpdate;
6.  
7.         [DoNotSerialize] public ValueInput inputAction;
8.         [PortLabelHidden] public ValueOutput outputValue;
9.  
10.         protected InputAction action;
11.         protected Guid lastAction;
12.         protected string type;
13.         protected bool actionRunning;
14.         protected float _floatValue;
15.         protected Vector2 _vector2Value;
16.         protected bool _boolValue;
17.  
18.         public override EventHook GetHook(GraphReference reference)
19.         {
20.             action = Flow.FetchValue<InputAction>(inputAction, reference);
21.             if (action.id != lastAction)
22.             {
23.                 Debug.Log(lastAction);
24.                 lastAction = action.id;
25.                 type = action.expectedControlType;
26.  
27.                 outputValue = null;
28.  
29.                 if (type == "Vector2")
30.                     outputValue = ValueOutput<Vector2>(nameof(outputValue));
31.                 else if (type == "Float")
32.                     outputValue = ValueOutput<float>(nameof(outputValue));
33.                 else if (type == "Button")
34.                     outputValue = ValueOutput<bool>(nameof(outputValue));
35.             }
36.             return base.GetHook(reference);
37.         }
38.  
39.         protected override void Definition()
40.         {
41.             base.Definition();
42.             inputAction = ValueInput(nameof(inputAction), (InputAction)default);
43.  
44.             if (action == null) return;
45.             type = action.expectedControlType;
46.            
47.             if (type == "Vector2")
48.                 outputValue = ValueOutput(nameof(outputValue), _ => _vector2Value);
49.             else if (type == "Float")
50.                 outputValue = ValueOutput(nameof(outputValue), _ => _floatValue);
51.             else if (type == "Button")
52.                 outputValue = ValueOutput(nameof(outputValue), _ => _boolValue);
53.         }

When using the GetHook method, I keep getting a duplicate output error:

Code (CSharp):

1. ArgumentException: Duplicate output for 'outputValue'

Is this possible?

Thanks,
