spawning instantiated prefab on touch after he had been destroyed

Hello
i did a script which can on one touch spawn object (instantiated prefab), maximum amount of this objects in game is 3 and when they are not visible they will be destroyed, but i need these prefabs to be able spawn again after they had been destroyed

I tried this but it does not work:

Code (CSharp):

1. public class CreatingCan: MonoBehaviour //This Script is added to gameObject canCreator in hiearchy
2. {
3.  
4.     public GameObject Can;
5.     public int numberOfCans;
6.     public bool canSpawn = true;
7.  
8.     private void Start()
9.     {    
10.         numberOfCans = 0;
11.     }
12.     void Update()
13.     {
14.         if (Input.touchCount > 0)
15.         {        
16.             Touch touch = Input.GetTouch(0);
17.             Vector2 TouchPosition = Camera.main.ScreenToWorldPoint(touch.position);
18.             if (touch.phase == TouchPhase.Began && canSpawn == true)
19.             {    
20.                 if (Instantiate(Can, TouchPosition, Quaternion.identity))  
21.                 {
22.                     numberOfCans++;              
23.                 }
24.             }
25.         }
26.  
27.         if (numberOfCans >= 3)
28.         {
29.             canSpawn = false;
30.         }
31.  
32.     }
33.  
34. }

Code (CSharp):

1.  
2. public class fallingCan : MonoBehaviour //THIS SCRIPT IS ADDED TO PREFAB
3. {
4. CreatingCan CC;
5. private void Update()
6. {
7.     if (transform.position.x < Camera.main.transform.position.x - 10)
8.     {
9.         Destroy(gameObject);
10.            CC.numberOfCans--;    
11.     }  
12. }

 

This is not super helpful.

As it is you never reset the canSpawn variable when the number of cans is reduced.
Try replacing

Code (CSharp):

1.         if (numberOfCans >= 3)
2.         {
3.             canSpawn = false;
4.         }

with

Code (CSharp):

1. canSpawn = numberOfCans < 3;

 

i can spawn 3 objects but then when they are destroyed i cannot spawn this objects again and also i get error message "Destroying assets is not permitted to avoid data loss"
