Bug Virtual Mouse not monitored

Hello,

Here is the context:
I am working on a video game where I want the player to be able to switch easily between the keyboard/mouse and gamepad. When using the gamepad, I want to enable a virtual mouse input that will allow the player to navigate in UI like it can with the mouse.

The issue:
When the player starts using the gamepad, the player input automatically switches on the gamepad control scheme. On a custom script, I detect this control scheme change and enable (

gameObject.SetActive(true)

) the cursor (Virtual Mouse Input, taken from the samples in Input System). However, when I try to click the button with the virtual mouse, nothing happens.
Until I move the mouse. Then the virtual mouse works as expected.
It is an issue in that, most of the time, the user will take its gamepad, switching the control scheme, and is not going to interact with keyboard/mouse from here.


Description:
- gamepad is activated
- the virtual mouse click works
- switch on keyboard/mouse control scheme
- the cursor is disabled
- switch again on gamepad
- the cursor is enabled
- the cursor can be moved *but* the click does not work anymore

Investigation:
I dig on to investigate what I've been missing. I found that state changes from my Virtual Mouse (even if added to the InputSystem) are never monitored.
So, in the

InputManager.UpdateState

, the

ProcessStateChangeMonitors

call returns false, preventing

FireStateChangeNotifications

to be called, forwarding click event and so on.
So why does it work when moving the mouse? Because it triggers an event (I think it is due to the control scheme change) that will call the

InputManager.AddStateChangeMonitor

method, refreshing the monitors and will finally add the Virtual Mouse to the

m_StateChangeMonitors

, fixing the issue.


Perhaps it is me that did not understand how to setup correctly the virtual mouse and/or switching correctly the activation, so I am searching for help about that or what new code line I should add to the Virtual Mouse so my virtual mouse becomes monitored correctly.

Note: I tried calling

InputUser.PerformPairingWithDevice(m_VirtualMouse, _playerInput.user)

to force pairing and monitoring, but it did not work. Also, I try adding the Virtual Mouse among the

playerInput.currentActionMap.devices

because it forces the monitoring refresh. But it didn't work (my real mouse was not working anymore).

 

Bump!
