Moving an hole in a plane

Hi i saw in a video on Youtube a script to modify the position of an Hole in a plane. I tried this script and it worked well, and i thought that it could be perfect for my project. When i tried to apply the script in more object it didn't work, so i tried many different ways to solve this problem. After many researches and tests i found out that if the script, doesn't have attached an object in position(0,0,0) dosen't work. I just want to know if there is a solution to my problem, and if someone could explain to me why is that.

This is the script:

 [Header ("Hole Mesh")]
 [SerializeField]
 private MeshFilter _holeMeshFilter;
 [SerializeField]
 private MeshCollider _holeMeshCollider;
 [Header("Hole Radius")]
 [SerializeField]
 private float _holeRadius; 
 [SerializeField]
 private Transform _holeCenter; 
 private Mesh _mesh; 
 [SerializeField] private List _holeVertices; 
 [SerializeField] private List _offset; 
 [SerializeField] private int _holeVerticesCount; 



 private void Start()
 {
     _holeVertices = new List<int>();
     _offset = new List<Vector3>();
     _mesh = _holeMeshFilter.mesh;

     FindHoleVertices();

 }

 private void Update()
 {
     UpdateHoleVertices();
     
 }

 private void FindHoleVertices()
 {
     for (int i = 0; i < _mesh.vertices.Length ; i++)
     {
         float distance = Vector3.Distance(_holeCenter.position, _mesh.vertices[i]);
         if(distance < _holeRadius)
         {
             _holeVertices.Add(i);
             _offset.Add(_mesh.vertices[i] - _holeCenter.position);
         }
         
     }
     _holeVerticesCount = _holeVertices.Count;
 }

 
 
 private void UpdateHoleVertices()
 {
     Vector3[] Vertices = _mesh.vertices;
     for (int i = 0; i < _holeVerticesCount; i++)
     {
         Vertices[_holeVertices[i]] = _holeCenter.position + _offset[i];
     }
     _mesh.vertices = Vertices;
     _holeMeshFilter.mesh = _mesh;
     _holeMeshCollider.sharedMesh = _mesh;
 }


 private void OnDrawGizmos()
 {
     Gizmos.color = Color.red;
     Gizmos.DrawWireSphere(_holeCenter.position, _holeRadius);

 }

Thanks in advance.
