Unity New Input System not showing up serialized field
I'm using Unity 2019.1.4f1 and just got the New Unity Input System from the Package Manager. I'm unable to see the serialized field for linking the generated C# class in the monobehaviour that intends to use it.
I've made public and added the [SerializeField] attribute to the instance but it won't show the field in the inspector. Therefore I tried creating the instance programatically inside my Monobehavior but it's not working. My SelectDestination method is not getting called
public class PlayerInputManager : MonoBehaviour
{
[SerializeField]
public PlayerInput Input;
private void Awake()
{
Input = new PlayerInput();
Input.Enable();
}
void OnEnable()
{
Input.Player.SelectDestination.performed += ctx => SelectDestination();
Input.Player.SelectTarget.performed += ctx => SelectDestination();
Input.Player.W.performed += ctx => SelectDestination();
Input.Player.Enable();
}
void OnDisable()
{
Input.Player.SelectDestination.performed -= ctx => SelectDestination();
Input.Player.SelectTarget.performed -= ctx => SelectDestination();
Input.Player.W.performed -= ctx => SelectDestination();
Input.Player.Disable();
}
void SelectDestination()
{
Debug.Log("BLA");
}
}
It should log "BLA" when W, Left Click or Right Click is pressed
If this comes to use, the following code is generated by Unity from my Player Input Import Settings:

The way of creating the instance programatically works.
public class PlayerInputManager : MonoBehaviour
{
[SerializeField]
public PlayerInput Input;
private void Awake()
{
Input = new PlayerInput(); <<<<<<<<<<<
Input.Enable();
}
...
}
The only problem was that the input backend wasn't activated. Once restarted Unity a message popped addressing this issue, and it worked afterwards. This changing backend option came also when importing the new Input System, but somehow I managed to click not changing it
