Questions & Answers

private void Awake()
{
Controls.InputMap.Player.Charge.performed += Charge;
Controls.InputMap.Player.Teleport.performed += Teleport;
}

    private void Teleport(InputAction.CallbackContext context) => StartCoroutine(Teleport());
    private void Charge(InputAction.CallbackContext context) => StartCoroutine(Charge());


    private void OnDestroy()
    {
        print("destroyed");
        Controls.InputMap.Player.Charge.performed -= Charge;
        Controls.InputMap.Player.Teleport.performed -= Teleport;
    }

Every time I restart scene the console is full of MissingReferenceExceptions referenced to the InputSystem callbacks.

Despite the fact I unsubscribe from this event in OnDestroy. How do I properly unsubscribe from this event?
