2D Raycasting and interacting with 2D Objects,

I would like to know how to transform this script (Raycast Manager) to fit the 2D character. I've been looking for that so long but I still cant find the right way.. And also I want to know if there is a mistake in the Object Properties Script. My goal here is when I get closer to the object be able to press ''E'' and interact with the object.

Thanks in advance!

The RaycastManager Script:

public class RaycastManager : MonoBehaviour { private GameObject raycastedObj;

 public float rayLenght = 5f;
 public LayerMask newLayerMask;
 public PlayerStats PlayerStats;

 void Update()
 {
     RaycastHit hit;
     Vector3 forward = transform.TransformDirection(Vector3.forward);

     if(Physics.Raycast(transform.position, forward, out hit, rayLenght, newLayerMask.value))
     {
         if (hit.collider.CompareTag("Consumable"))
         {
             raycastedObj = hit.collider.gameObject;

             if(Input.GetKeyDown(KeyCode.E))
             {
                 //Obj props.
                 raycastedObj.GetComponent<ItemProperties>().Interaction(PlayerStats);
             }
         }
     }
 }

}

The Object Properties Script:

public class ItemProperties : MonoBehaviour { public string itemName;

 [SerializeField] private bool food;
 [SerializeField] private bool water;
 [SerializeField] private bool health;
 [SerializeField] private float value;
 [SerializeField] private PlayerStats PlayerStats;

 public void Interaction(PlayerStats playerVitals)
 {
     if (food)
     {
         playerVitals.HungeBar.value += value;
         this.gameObject.SetActive(false);
     }
 }

} ,
