Deactivating Objects (Random..)

Unity Engine
,

My problem is that, I have created a Random Generator script that Activate Random GameObjects but once that all gameobject activated, it doesn’t work more. And I want to active only one GameObject once(Previously activated GameObject should be Deactivate.)So this is my code

public class RandomColorGenerator : MonoBehaviour
{
    public GameObject Yellow, Red, Blue, Green;
    public void Generator()
    {
        List  <GameObject> colors = new List<GameObject>();
        colors.Add(Yellow);
        colors.Add(Blue);
        colors.Add(Red);
        colors.Add(Green);

       colors[Random.Range(0, colors.Count)].SetActive(true);

    }
}

Please help! (sorry for bad English!)

Try this

public class RandomColorGenerator : MonoBehaviour
{
    public List  <GameObject> colors
    GameObject picked = null;

    public void Generator()
    {
        picked?.SetActive(false);
        picked = colors[Random.Range(0, colors.Count)];
        picked.SetActive(true)
    }
}

Thank you very much! Saved My Life!:wink: Another problem. I want to activate a certain button, on every randomized card. I mean if the ‘Red’

 public void ActiveIfCardIsCorrect()
    {  if(picked = colors[0])
        {
            RomeButton.SetActive(true);
        }
        if (picked = colors[1])
        {
          LondonButon.SetActive(true);
        }
        if (picked = colors[2])
        {
            TajmahalButton.SetActive(true);
        }
        if (picked = colors[3])
        {
            EiffelButton.SetActive(true);
        }
        if (picked = colors[4])
        {
            ChristButton.SetActive(true);
        }


    }

card activated, Red button should be activated. I tried this but not working,

Here in each of the “if” condition you are doing

picked = colors[X]

The problem is: “=” is an affectation operator, and you want to do a test, so it’s “==” instead.

It works but not properly. When a Shape activated, it doesn’t deactivate. Script here and Additionally I created a Button to Random Objects and Activate buttons according to the Activated object. It means both functions.

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

public class RandomColrGenerator : MonoBehaviour
{
    public List<GameObject> colors;

    public GameObject RomeButton, LondonButon, TajmahalButton, EiffelButton, ChristButton;

    GameObject picked = null;

    public void Generator()
    {
        picked?.SetActive(false);
        picked = colors[Random.Range(0, colors.Count)];
        picked.SetActive(true);

       
      

       

    }

    public void ActiveIfCardIsCorrect()

      
    {
       

        if(picked == colors[0])
        {
            RomeButton.SetActive(true);
        }
        if (picked == colors[1])
        {
          LondonButon.SetActive(true);
        }
        if (picked == colors[2])
        {
            TajmahalButton.SetActive(true);
        }
        if (picked == colors[3])
        {
            EiffelButton.SetActive(true);
        }
        if (picked == colors[4])
        {
            ChristButton.SetActive(true);
        }


    }
}
