My usual way of using the new input system

[RoDu]

Im using a PlayerInput module on the player, and i use the mode: invoke unity events
then i use this script on the player.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;

public class PlayerController : MonoBehaviour
{
    Vector2 readOnMoveInput;
    Vector3 moveDirection;

    private void Update()
    {
        moveDirection = new Vector3(readOnMoveInput.x, readOnMoveInput.y, 0);
        // Use movedirection to move player
    }

    public void OnMove(InputAction.CallbackContext context)
    {
        readOnMoveInput = context.ReadValue<Vector2>();
        print(context.ReadValue<Vector2>());
    }
    public void OnFire(InputAction.CallbackContext context)
    {
        // Fire Function goes here
        print("FIRE!!!");
    }
}
