Accelerometer.current == null, but Input.acceleration used to work fine

Unity Engine

Making a mobile game where the player moves side to side by tilting the device. Input.acceleration used to work to move the character.

Switching over to the new Accelerometer.current.acceleration.ReadDefaultValue() method does not work for me due to Accelerometer.current returning null.

Does anyone have a solution to this? Below is a snippet of the check I’m using to enable the Accelerometer and to get it’s current value.

    private void OnEnable()
    {
        gameplayInputsActions.Enable();
        if (Accelerometer.current != null)
        {
            InputSystem.EnableDevice(Accelerometer.current);
        }
    }

    private void OnDisable()
    {
        gameplayInputsActions.Disable();

        if (Accelerometer.current != null)
        {
            InputSystem.DisableDevice(Accelerometer.current);
        }
    }

private void Update()
    {
        if (Accelerometer.current != null)
        {
            Debug.Log(Accelerometer.current.acceleration.ReadValue());
        }

        ReceiveAxisInput();
       //ReceieveTapInput();
    }

    private void ReceiveAxisInput()
    {
        switch (currentControlScheme)
        {
            case ControlScheme.Tilt:
                Vector3 acceleration = gameplayInputsActions.Player.Movement.ReadValue<Vector2>();

                Vector3 tilt = Accelerometer.current != null ? Accelerometer.current.acceleration.ReadDefaultValue() : Vector3.zero;
              
                Vector3 targetVector = acceleration + tilt;
                //Debug.Log(acceleration);
                axisInput = targetVector;

                break;
            case ControlScheme.Drag:
                break;
        }

        //Vector2 keyInput = moveAction;

        Vector2 targetInput = axisInput;

        axisInput = targetInput;
    }

On which platform, which unity version, which input system version?
If you connect to a player via window → analysis → input debugger → remote does it see any accelerometer sensors?

Platform: Android Samsung Galaxy S20+
Unity Version: 2020.3.16f1
Input System Version: 1.0.2

I assume this what you’re talking about? There doesn’t seem to be an accelerometer under my mobile device.

Look into this more today and I’m still not able to figure out why this isn’t working. I’ve tried every sensor of this official unity list and I can’t get it working.

Can anyone link me to a tutorial or give me a breakdown of how to get mobile game tilt controls? Something like Doodle Jump where you rotate the phone side-to-side to get the character to move?

I’ve tried the *.current.ReadDefaultValue() of all of these listed below.

  • LinearAccelerationSensor
  • Gyroscope
  • AttitudeSensor
  • AccelerometerSensor

Did you resolve this.
My Accelerometer was working fine using Input System Version 1.0.2.
Then I updated to 1.1.1 and now Accelerometer.current is always null with no other changes.
I will look into it more tomorrow.

Unfortunately I did not resolve this. I ended up toggling the preferred input system to “both”- in the project settings to use the new system and the old system in tandem so I could continue using input.acceleration

Solved in 1.2.0.
Accelerometer null is mentioned as a fix in the release notes.

It’s been quite some time since I made this thread. Much appreciated for you updating me on this after all this time. Thank you so much, I’ll be checking this out today.
