Generated c# Class Current Control Scheme

Unity Engine

Hello together, i have a question is there a way to find out which control scheme is currently being used or which input device, i want to switch ui icons. I know IT works with PlayerInput but i use the Generated c# Class Option.

Thanks

You can get it by referencing the InputUser like this:

InputUser user = InputUser.PerformPairingWithDevice(device);
user.ActivateControlScheme("Gamepad");

// This will print 'Gamepad(<Gamepad>)'
print(user.controlScheme);

// This will print 'Gamepad'
print(user.controlScheme.Value.name);

What I like to do is create a ScriptableObject so that I can easily customize the ui that is shown like this:

[CreateAssetMenu(menuName = "Control Scheme", fileName = "New Control Scheme")]

public class ControlScheme : ScriptableObject
{
    [SerializeField] string displayName;
    [SerializeField] Sprite icon;

    public string Name => name;
    public string DisplayName => displayName;
    public Sprite Icon => icon;
}

Hey Thanks for the reply well i think the InputUser is only working with a PlayerInput in the Scene ?

I don’t completely understand but I am assuming you are referring to the PlayerInput component. The InputUser API, as far as I know is not related to it. You can do it completely through code as is explored in this thread: Manual Local Multiplayer Using InputDevices
You can get the current control scheme in the PlayerInput component using: PlayerInput.currentControlScheme

idk is this correct or not but it works for now maybe someone has a better solution for me but for now i can detect if a deveice has changed and i can send a event to change my ui icons

        // Send Event to UI Elements to Change Icons if the ControlScheme has changed
        if (cacheControlScheme != currentControlScheme) {
