How to make moving platforms?

Question

C++ / C#

I'm making a 2D platformer. I made a platform with such a script

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

public class MonsterBehaviour : MonoBehaviour {

    public float speed = 3f;

    public Transform[] waypoints;
    private int ArrayIndex;

    void Start () {
  ArrayIndex = 0;
    }
    

    void Update () {
  

  transform.position = Vector2.MoveTowards (transform.position, waypoints[ArrayIndex].transform.position, speed * Time.deltaTime);
  CheckWayPoint ();
    }

    void CheckWayPoint(){
  int test = ArrayIndex + 1;

   if (Vector2.Distance(transform.position,waypoints[ArrayIndex].transform.position)<0.1f) {
   if (test > 1) {
    ArrayIndex = 0;
   } else {
    ArrayIndex++;
   }

    }
}
}

When the character stands on the platform and it moves down, the Persian, as it were, breaks away from it.
How to make it not come off the platform?

Answer 1

It is necessary to make the player a child of the platform.
