Question Deactivating Objects (Random..)

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

Code (CSharp):

1. public class RandomColorGenerator : MonoBehaviour
2. {
3.     public GameObject Yellow, Red, Blue, Green;
4.     public void Generator()
5.     {
6.         List  <GameObject> colors = new List<GameObject>();
7.         colors.Add(Yellow);
8.         colors.Add(Blue);
9.         colors.Add(Red);
10.         colors.Add(Green);
11.  
12.        colors[Random.Range(0, colors.Count)].SetActive(true);
13.  
14.     }
15. }

Please help! (sorry for bad English!)

 

Try this

Code (CSharp):

1. public class RandomColorGenerator : MonoBehaviour
2. {
3.     public List  <GameObject> colors
4.     GameObject picked = null;
5.  
6.     public void Generator()
7.     {
8.         picked?.SetActive(false);
9.         picked = colors[Random.Range(0, colors.Count)];
10.         picked.SetActive(true)
11.     }
12. }

 

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

Code (CSharp):

1.  public void ActiveIfCardIsCorrect()
2.     {  if(picked = colors[0])
3.         {
4.             RomeButton.SetActive(true);
5.         }
6.         if (picked = colors[1])
7.         {
8.           LondonButon.SetActive(true);
9.         }
10.         if (picked = colors[2])
11.         {
12.             TajmahalButton.SetActive(true);
13.         }
14.         if (picked = colors[3])
15.         {
16.             EiffelButton.SetActive(true);
17.         }
18.         if (picked = colors[4])
19.         {
20.             ChristButton.SetActive(true);
21.         }
22.  
23.  
24.     }

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

 

Here in each of the "if" condition you are doing

Code (CSharp):

1. 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.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class RandomColrGenerator : MonoBehaviour
6. {
7.     public List<GameObject> colors;
8.  
9.     public GameObject RomeButton, LondonButon, TajmahalButton, EiffelButton, ChristButton;
10.  
11.     GameObject picked = null;
12.  
13.     public void Generator()
14.     {
15.         picked?.SetActive(false);
16.         picked = colors[Random.Range(0, colors.Count)];
17.         picked.SetActive(true);
18.  
19.        
20.      
21.  
22.        
23.  
24.     }
25.  
26.     public void ActiveIfCardIsCorrect()
27.  
28.      
29.     {
30.        
31.  
32.         if(picked == colors[0])
33.         {
34.             RomeButton.SetActive(true);
35.         }
36.         if (picked == colors[1])
37.         {
38.           LondonButon.SetActive(true);
39.         }
40.         if (picked == colors[2])
41.         {
42.             TajmahalButton.SetActive(true);
43.         }
44.         if (picked == colors[3])
45.         {
46.             EiffelButton.SetActive(true);
47.         }
48.         if (picked == colors[4])
49.         {
50.             ChristButton.SetActive(true);
51.         }
52.  
53.  
54.     }
55. }
