Raycast not working in Unity 2D. What to do?

Question

C++ / C#

I have one control script sprite which is the player and another object tagged "enemy" which is the enemy. Here is the line of the control script that is responsible for the raycast:

void Punch()
    {
        RaycastHit2D hit = Physics2D.Raycast(gameObject.transform.position, transform.TransformDirection(Vector2.right), ray_length);
        Debug.DrawRay(gameObject.transform.position, Vector2.right * ray_length, Color.red);
        
        if(Input.GetKeyDown(KeyCode.E))
        {
            if (hit.collider != null)
            {
                if(hit.collider.gameObject.CompareTag("enemy"))
                {
                    Debug.Log("enemy");
                }
            } 
        }
    }

And here is the entire player script if needed:

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

public class character_script_2 : MonoBehaviour
{
    public string name;
    public float velocity;
    public float JumpForce;
    public float timer;
    public float punch_time;
    public float ray_length;

    public floor_on floortouch;
    public GameObject punch;

    private Rigidbody2D rb1;

    public RaycastHit2D hit;
    
    void Awake()
    {
        rb1 = gameObject.GetComponent<Rigidbody2D>();
    }
    void Update()
    {
        if(timer > 0)
        {
            timer -= Time.deltaTime;
        }
        //if(punch_time > 0)
        //{
        //    punch_time -= Time.deltaTime;
        //}
        //else if(punch_time <= 0)
        //{
            
        //}

        floor_on floortouch;

        Move(); 
        Jump();
        Punch();
    }
    void Punch()
    {
        RaycastHit2D hit = Physics2D.Raycast(gameObject.transform.position, transform.TransformDirection(Vector2.right), ray_length);
        Debug.DrawRay(gameObject.transform.position, Vector2.right * ray_length, Color.red);
        
        if(Input.GetKeyDown(KeyCode.E))
        {
            if (hit.collider != null)
            {
                if(hit.collider.gameObject.CompareTag("enemy"))
                {
                    Debug.Log("enemy");
                }
            } 
        }
    }
    // Движения персонажа
    void Move()
    {
        if (Input.GetAxisRaw ("Horizontal") > 0) 
        {
            transform.Translate (Vector2.right * velocity * Time.deltaTime);
            transform.eulerAngles = new Vector2 (0, 0);
            Debug.Log(Input.GetAxisRaw ("Horizontal"));
        }
        else if (Input.GetAxisRaw ("Horizontal") < 0) 
        {
            transform.Translate (Vector2.right * velocity * Time.deltaTime);
            transform.eulerAngles = new Vector2 (0, 180);
            Debug.Log(Input.GetAxisRaw ("Horizontal"));
        }
    }
    
    // Прыжок персонажа был еще той занозой в заднице
    void Jump()
    {
        if (Input.GetKeyDown(KeyCode.Space) && floortouch.on_floor == true && timer <= 0.0f)
        {
            rb1.AddForce(Vector2.up * JumpForce, ForceMode2D.Impulse);
            floortouch.on_floor = false;
        }
        else if(Input.GetKeyDown(KeyCode.Space) && floortouch.on_floor == false)
        {
            rb1.AddForce(Vector2.down * 40, ForceMode2D.Impulse);
            floortouch.on_floor = true;
            timer = 0.10f;
        } 
    }
}

Here is the player:

Here is the enemy:


The raycast touches the player and the E button is pressed, but for some reason "enemy" is not displayed in the console. And also I don't know how to change rotate raycast. I searched all the forums but didn't find the answer.

It is not very clear where and when the method is called Punch(), in theory you have this part

if(Input.GetKeyDown(KeyCode.E))
        {
            if (hit.collider != null)
            {
                if(hit.collider.gameObject.CompareTag("enemy"))
                {
                    Debug.Log("enemy");
                }
            } 
        }

should be in the method Update(), I hope it helped somehow))
