How do I use controller knob input like mouse position? (New Input System)

Questions & Answers
1

I recently made a dash ability that dashes towards the mouse, using the new input system. I want this ability to also work if using a controller, by reading the direction the knob is being pushed and using that for the direction of the dash. Does anyone know how I can set it up so that the direction the knob is being pressed works like the direction to the mouse from the player?

I had tried this setup:

but when dashing on the controller it would ignore the direction I was pressing the knob, and just dash downwards diagonally to the left, regardless of the mouse’s position even. The part of the script I am using to read the input and dash looks like this:

    public void Dash(InputAction.CallbackContext context)
    {

        Vector2 dashAim = context.ReadValue<Vector2>();

        Vector3 dashAim3 = dashAim;
        Vector3 dashDir3 = (dashAim3 - camera.WorldToScreenPoint(rb.transform.position)).normalized;
        Vector2 dashDir = new Vector2(dashDir3.x, dashDir3.y);

        //if button has been pressed
        if (startDash == true)
        {

            //dash
            rb.velocity = dashDir * dashSpeed;

            cantAirJump = true;
            startDash = false;

        }

    }

I have barely used the Input System, but from what I understand, the Position [Mouse] entry will return the position of the mouse in the Screen Space ((0,0) → (Screen.width, Screen.height)) while the Left Stick [GamePad] certainly returns values between (-1,-1) → (1,1), so Vector3 dashDir3 = (dashAim3 - camera.WorldToScreenPoint(rb.transform.position)).normalized; does not make sense here.

I believe you will have to create two actions, a DashWithMouse and a DashWithStick action.

FOLLOWING CODE NOT TESTED

 // To be called instead of the Dash function when adding the listener
 public void ReadMouseInput(InputAction.CallbackContext context)
 {

     Vector2 mousePosition = context.ReadValue<Vector2>();
     Vector3 direction = (mousePosition - camera.WorldToScreenPoint(rb.transform.position)).normalized;
     Dash(new Vector2(direction.x, direction.y));
 }

 // Callback of the Left Stick
 public void ReadStick(InputAction.CallbackContext context)
 { 
     Vector2 stickDirection = context.ReadValue<Vector2>().normalized;
     Dash(new Vector2(stickDirection.x, stickDirection.y));
 }

 public void Dash(Vector2 direction)
 {
     //if button has been pressed
     if (startDash == true)
     {

         //dash
         rb.velocity = direction * dashSpeed;

         cantAirJump = true;
         startDash = false; 
     } 
 }
