enable object when other is disabled and so on

how would a script look like that allows me to disable an item once i enter the trigger of it, and when i enter the trigger, another item enables itself and so on? example; cube1 disables and cube2 enables, cube2 disables and cube3 enables, cube3 disables and cube4 enables, and so

 

For this to work you have to assign Cube2 to the slot ConnectedGameObject and attach this script to Cube1.
Cube1 must have a trigger collider. The player should have the tag "Player".

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class ConnectedGameObjects : MonoBehaviour
7. {
8.     public GameObject ConnectedGameObject;
9.  
10.     //When the player triggers this GO it will disable itself and active the connected GameObject
11.     private void OnTriggerEnter(Collider other)
12.     {
13.         //Check to see if the tag on the collider is equal to Player
14.         if (other.tag == "Player")
15.         {
16.             Debug.Log("Triggered by Player");
17.             // Deactivate myself
18.             this.gameObject.SetActive(false);
19.  
20.             // Activate my connected GameObject
21.             ConnectedGameObject.SetActive(true);
22.         }
23.     }
24. }
25.  
26.
