How do I rotate an object using Vector2 inputs? (New Input System)

Questions & Answers
1

I have a dash ability in my game that causes the player to dash towards the mouse or the direction the controller knob is being pressed. That all works fine. I want to rotate an arrow-like game object using the input to indicate where the player will dash. I already have a reference to the game object:

public GameObject dashAim;

But i’m not sure how to use the inputs for the rotation. I’ve had help with this before, but this was using the old input system:

public class RotateToMouse : MonoBehaviour
 {
     void Update()
     {
         //rotation
         Vector3 mousePos = Input.mousePosition;
         mousePos.z = 5.23f;
 
         Vector3 objectPos = Camera.main.WorldToScreenPoint(transform.position);
         mousePos.x = mousePos.x - objectPos.x;
         mousePos.y = mousePos.y - objectPos.y;
 
         float angle = Mathf.Atan2(mousePos.y, mousePos.x) * Mathf.Rad2Deg;
         transform.rotation = Quaternion.Euler(new Vector3(0, 0, angle));
     }
 }

i’m just not quite sure how to repurpose this with the new inputs. I already tried this:

dashAim.transform.rotation = Quaternion.Euler(new Vector3(direction.x, direction.y));

but it didn’t do anything. Does anyone know how I can do this? Here’s the code i’m using for the inputs, thanks to @Hellium

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

        Vector2 mousePosition = context.ReadValue<Vector2>();
        Vector3 mousePosition3 = mousePosition;
        Vector3 direction = (mousePosition3 - 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));
    }

I’d really appreciate any help with this. Thanks!

You might be able to do something similar to how you handle dash.

public class RotateToMouse : MonoBehaviour
{
    void Start()
    {
        // Add the listeners to the actions
    }

    void Update()
    {
        // Not needed anymore
    }

    public void ReadMouseInput(InputAction.CallbackContext context)
    {
        Vector2 mousePosition = context.ReadValue<Vector2>();
        Vector2 objectPosition = (Vector2) Camera.main.WorldToScreenPoint(transform.position);
        Vector2 direction = (mousePosition - objectPosition).normalized;

        RotateAim(direction);
    }

    public void ReadStick(InputAction.CallbackContext context)
    {
        Vector2 stickDirection = context.ReadValue<Vector2>().normalized;

        RotateAim(stickDirection);
    }

    public void RotateAim(Vector2 direction)
    {  
        float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
        transform.rotation = Quaternion.Euler(new Vector3(0, 0, angle));
    }
}
