I tried to add Raycast for shooting by following a tutorial on youtube but I still get 2 CS0029 Error Messages the first one saying

Assets\Shooting.cs(19,30): error CS0029: Cannot implicitly convert type 'bool' to 'UnityEngine.RaycastHit'

And the second one saying

Assets\Shooting.cs(21,13): error CS0029: Cannot implicitly convert type 'UnityEngine.RaycastHit' to 'bool'

here is my script

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

public class Shooting : MonoBehaviour
{
    public Transform firePoint;

    void Update() 
    {
        if (Input.GetButtonDown("Fire1"))
        {
            Shoot();
        }
    }

    void Shoot()
    {
        RaycastHit hitInfo = Physics.Raycast(firePoint.position, firePoint.right);

        if (hitInfo)
        {
            Debug.Log(hitInfo.transform.name);
        }
    }
}

What I have tried:

I tried to look for spelling mistakes but i LITTERALLY have the same script as in the tutorial one.

Posting the code that is raising the error would be of more help here. Believe line 15-25 from file shooting.s should be good enough.

i accidentally forgot to post the script. Now I added it

Tutorial might be old. Learn using IDE, intellisense in it would have given clue if not error on what is the method return type.

Here, have a look: Unity - Scripting API: Physics.Raycast[^]
Physics.Raycast returns a boolean type. You have assigned that to variable of type RaycastHit and thus the error.

It straight away returns true if the ray intersects with a Collider, otherwise false.

Thus,

C#

void Shoot()
{
  if (Physics.Raycast(firePoint.position, firePoint.right))
  {
    // Ray intersects
  }
}

Go through some documentation and article to learn about it, like:
How to Create a Raycast in Unity 3D | Studica Blog[^]

UPDATE:
A sample for you

C#

void FixedUpdate()
    {
        // Bit shift the index of the layer (8) to get a bit mask
        int layerMask = 1 << 8;

        // This would cast rays only against colliders in layer 8.
        // But instead we want to collide against everything except layer 8. The ~ operator does this, it inverts a bitmask.
        layerMask = ~layerMask;

        RaycastHit hit;
        // Does the ray intersect any objects excluding the player layer
        if (Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), out hit, Mathf.Infinity, layerMask))
        {
            Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * hit.distance, Color.yellow);
            Debug.Log("Did Hit");
        }
        else
        {
            Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * 1000, Color.white);
            Debug.Log("Did not Hit");
        }
    }

Suggestion: Please go through the link above and examples there instead of trying to follow some youtube. Until you understand basics and how to use IDE, it would be difficult for you to follow.
