I have a Unity 5.4 app where the pen doesn’t work when played on a MS Surface with Windows 10 pro but touch input does work. I am using Input.GetMouseButtonDown, Input.mousePosition, etc. to capture user input to draw lines in my app. What do I need to do to get the pen to work?
Exactly the same problem I have. Unity exe app not support pen on Microsoft Surface 3.
The answer was that the bluetooth pen does not work in the Unity Windows Player. Touch would work and simple stylus (replicating touch) would work.
Exactly the same situation.
Maybe anyone found a solution?
