New Input System how to fire events continuously?

[ToastedShrimp]

Hi guys,

I’m using the “new” input system, and I’m trying to get an OnMove event to continuously fire if the key binding is held down. I figured the best way to do this would be to have a bool that calls OnMove in Update if true, but in practice I’m not entirely sure how to get it to work, since the actions obviously need a callback context and I’m not even entirely sure what that is. Here’s what I tried:

public class PlayerController : MonoBehaviour
{
    [SerializeField] private int moveSpeed = 5;
    public bool isMoving;
    private Rigidbody2D rb;
    private void Awake()
    {
        rb = GetComponentInParent<Rigidbody2D>();
    }

    public void OnMoveStart(InputAction.CallbackContext context)
    { 
        rb.velocity = new Vector2(moveSpeed * InputManager.inputActionAsset.Ground.Move.ReadValue<float>(), 0);
        isMoving = true;
    }

    public void OnMoveEnd(InputAction.CallbackContext context)
    {
        isMoving = false;
    }
    private void Update()
    {
        if (isMoving)
        {
            OnMoveStart(); //obviously this line is not syntactically correct, as it needs a context parameter. rider's advice was to create a new instance of the callback context, which first of all doesn't work,but secondly I don't know how callback context works so it's confusing.

        }
    }
}

My Input Manager just subscribes the events to the input action asset and enables the action map, here it is:

public class InputManager : MonoBehaviour
{
    public static Controls inputActionAsset;
    public PlayerController Player;

    private void OnEnable()
    {
        inputActionAsset = new Controls();
        inputActionAsset.Ground.Move.started += Player.OnMoveStart;
        inputActionAsset.Ground.Move.performed += Player.OnMoveEnd;
        
        inputActionAsset.Enable();
    }


}

I made the Input Manager a child of the player which I intend on turning into a prefab to instantiate the player, because this seems like a good way to keep things separate. Thanks for any advice.

You can read the context and get a vector2 which can be used to move a player.

public class Player : MonoBehaviour
{
    private Vector2 movementDirection;

    public void UpdatePlayerMovementVector2(InputAction.CallbackContext context)
    {
        movementDirection = context.ReadValue<Vector2>();
    }
}

Then you could invoke that from the player input move event.

This will return a vector 2 (0, 0) that tells you the direction.

(1, 0) = right
(-1, 0) = left
(0, 1) = forward
(0, -1) = back
(1, 1) = forward right diagonal, etc

private void Update()
{
    transform.Translate(new Vector3(movementDirection.x, 0, movementDirection.y) * Time.deltaTime, Space.World);
}
