How would I use other without it being a collision script

I've seen people use "other" as a way to refrence the object the collider is colliding with but how would I use that in my raycast script?

 using UnityEngine;
 using System.Collections;
 
 public class CameraControll : MonoBehaviour
 {
     Vector3 Campos;
     public Transform player;
     public GameObject Player;
     int count = 0;
     public float Distance;
 
     public void Update()
     {
 
         RaycastHit hit;
         Ray LandingRay = new Ray(transform.position, Vector3.forward);
             if(Physics.Raycast(LandingRay, out hit, Distance))
         {
             if(hit.collider.tag == "wall" && transform.position - transform.position.out) // how would I put other in here
             {
 
             }
         }
 
         if (Input.GetKeyDown("q"))
         {
             count++;
         }
         else
         {
             if (Input.GetKeyDown("e"))
             {
                 count--;
             }
         }
         transform.position = Player.transform.position + Campos;
         transform.LookAt(player);
 
 
        
     }
 
     public void LateUpdate()
     {
         if (count == 0)
         {
             Campos = new Vector3(0f, 5f, -7f);
             Debug.Log(count);
         }
         else
         {
             if (count == 1)
             {
                 Campos = new Vector3(7f, 5f, 0f);
                 Debug.Log(count);
             }
             else
             {
                 if (count == 2)
                 {
                     Campos = new Vector3(0f, 5f, 7f);
                     Debug.Log(count);
                 }
                 else
                 {
                     if (count == 3)
                     {
                         Campos = new Vector3(-7f, 5f, 0);
                         Debug.Log(count);
                     }
                     else
                     {
                         if (count <= -1)
                         {
                             count = 3;
                         }
                     else
                         {
                             if (count <= 4)
                             {
                                 count = 0;
                             }
                         }
                     }
                 }
             }
         }
     }
