Can't interact with UI when using a virtual mouse,

Questions & Answers
1

I have created a “virtual” mouse through the new input system using:

Mouse RemoteMouse = InputSystem.AddDevice<Mouse>()

I create a new mouse state using:

pos = new Vector2Int(x, y);
newMouseState = new MouseState
{
    position = pos,
    delta = pos - m_prevMouseState.position,
    buttons = m_prevMouseState.buttons
};
newMouseState.WithButton(button, true);

And finally update its position using:

InputSystem.QueueStateEvent(RemoteMouse, newMouseState);
m_prevMouseState = newMouseState;

This all works fine for the most part. I am able to utilize this mouse as I would a normal mouse, however I am unable to interact with UI. When the virtual mouse is hovering over a button the button doesn’t transition to a hovered state, and when I click on a button or an input field nothing happens. EventSystem.current.IsPointerOverGameObject() always returns null.

Is this a limitation in the new input system? If not, any help would be appreciated.

I know that I could probaby work around this issue by using Mouse.WarpCursorPosition(), however I am unable to do so for my use case.

Do you have a Event - System? (UI → Event System)
