Toggle Game Objects with specific tag at runtime

Hi there,

I want to toggle Game Objects with a specific tag at runtime, therefore I am using a Game Objects with the attached script below to create an array of gameobjects which should turn the mesh off when clicking on a button (which activates the game object with the script).

Here is my code so far: using System.Collections; using System.Collections.Generic; using UnityEngine;

public class ToggleObjects : MonoBehaviour {

  public GameObject[] visibleList;
 
  void OnTriggerEnter(Collider other) {
      if (visibleList == null) {
          visibleList = GameObject.FindGameObjectsWithTag("wall");
      }
      foreach (GameObject visible in visibleList) {
          visible.GetComponent<MeshRenderer>().enabled=false;
      }

} }

Unfortunately my Object is still visible at runtime. Does anyone know how to fix that?

Many thanks in advance!
