problems with triggers

ah geez it took me a whole afternoon of research to come up with the wrong code. I think I have exhausted my resources so I'm turning it over to you guys for help.


I have a cylinder as a trigger that's intended to move a pool ball to the center of the table.
instead ball moves instantly to the center of the cylinder.



Here it is:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using System.Collections.Specialized;
4. using System.Security.Cryptography;
5. using UnityEngine;
6.  
7. public class Trigger2 : MonoBehaviour
8. {
9.  
10.     Vector3 targetPos = new Vector3(13f, 0f, 0.7f);
11.     public float speed = 5f;
12.     public float maxDistanceDelta = (13f);
13.  
14.     void OnTriggerEnter(Collider ballCollider)
15.     {
16.         if (ballCollider.gameObject.CompareTag("Ball"))
17.  
18.  
19.            ballCollider.transform.position = Vector3.MoveTowards(transform.position, targetPos, (speed * maxDistanceDelta * Time.deltaTime));
20.     }
21. }
