How to make Camera position Independent of its Rotation?

Question

Hello, in t$$anonymous$$s game, the camera is attached to the player as its c$$anonymous$$ld, the camera angle is fixed, even when the player rotates, but the camera position keeps changing every time the player rotates, as you can see below, the camera angle is fixed to one single direction, but when ever parent changes its rotation, it affects the c$$anonymous$$ld position, i dont want want my parents, rotation to affect my c$$anonymous$$ld Camera's position..

//Camera Rotation Script

     void Awake () {
         //pos = transform.localPosition;
         rotation = transform.rotation;
     }
 
 
 
 
     void LateUpdate () {
 
         transform.rotation = rotation;
         //transform.localPosition = pos;
     
     }

//Camera Position Script

 void Update () {
         if(t$$anonymous$$s.transform.rotation.y == 0f)
             t$$anonymous$$s.transform.localPosition = new Vector3(0f,13f,-4.5f);
         else if(t$$anonymous$$s.transform.rotation.y == 180f)
             t$$anonymous$$s.transform.localPosition = new Vector3(0f,13f,4.5f);
         else if(t$$anonymous$$s.transform.rotation.y == 90f)
             t$$anonymous$$s.transform.localPosition = new Vector3(-4.5f,13f,0f);
         else if(t$$anonymous$$s.transform.rotation.y == 270f)
             t$$anonymous$$s.transform.localPosition = new Vector3(4.5f,13f,0f);
     }

My solution would be to just don't mak the camera a c$$anonymous$$ld in the first place, since you only want it to follow the position, you could do that by adding a script like t$$anonymous$$s to your camera:

 using UnityEngine;
 using System.Collections;
 
 public class RotatingExample1 : MonoBehaviour
 {
     public Transform targetToFollow;
     public Vector3 targetOffset;
 
     private void LateUpdate()
     {
         transform.position = targetToFollow.position + targetOffset;
     }
 }

If you still insist on keeping it a c$$anonymous$$ld however, then t$$anonymous$$s code should help

 using UnityEngine;
 using System.Collections;
 
 public class RotatingExample2 : MonoBehaviour
 {
     public Vector3 offsetWorldPosition;
     private Quaternion fixedRotation;
 
     private void Awake()
     {
         fixedRotation = transform.rotation;
         //offsetWorldPosition = transform.localPosition; // Add t$$anonymous$$s if you don't want to set the value in the inspector
     }
 
     private void LateUpdate()
     {
         transform.rotation = fixedRotation;
         transform.localPosition = transform.parent.worldToLocalMatrix.MultiplyVector(offsetWorldPosition);
     }
 }
