Question DPad and Keyboard navigation not working with UI Toolkit

I want to control navigation through the menu system using the input system and it's fine with mouse clicking but not keyboard or Dpad.

• Player Input Debug is showing keyboard and DPad inputs correctly
• UI bindings are default
• Project -> Player -> Active Input Handling = Input System Package (New)
• Player Input behaviour is Invoke C# Events
• I use .clicked += for binding events in UI Toolkit

When the start menu appears, the follow code is run:

Code (CSharp):

1.         private void OnEnable()
2.         {
3.             if (GameMachine.Instance == null)
4.             {
5.                 throw new InvalidOperationException("Menu screen needs Bootstrap to run");
6.             }
7.  
8.             GameMachine.Instance.OnErrorChanged += ShowError;
9.             InputManager.UI.Enable();
10.             InputManager.Player.Disable();
11.             InputManager.Periscope.Disable();
12.             InputManager.DebugConsole.Disable();
13.         }
14.  
15.         private void OnDisable()
16.         {
17.             GameMachine.Instance.OnErrorChanged -= ShowError;
18.             InputManager.UI.Disable();
19.         }

I think it's because there is no focus set on the first item (Start) so the controller. I don't seem to be able to set focus and I think this is because the mouse take priority and the focus is lost.

Can a menu screen be used by both mouse and keyboard? Do I have to trap the change in control scheme (playerInput.onControlsChanged) and then disable the mouse to let the DPad/keys work?

Do I have to manually bind the movement of the focus and trap click events myself (I hope not).

Setup image below.



Apologies if this should go in the UI Toolkit forum; as it's a cross over, I have no idea where the bug lies.

Thanks in advance.

 

This works for me:

Code (CSharp):

1. void Start()
2. {
3.     EventSystem.current.SetSelectedGameObject(GameObject.Find("PanelSettings"));
4. }
5.  
6. void OnEnable()
7. {
8.     Button myButton = GetComponent<UIDocument>().rootVisualElement.Q<Button>("start-button");
9.     myButton.clicked += () => print("button clicked");
10.     myButton.Focus();
11. }

PanelSettings GameObject gets created as a child of InputSystemUIInputModule after entering play mode.
