How do I instantiate gameobject again after i destroy it?

Hi, i am new to C# and Unity.
what i'm trying to do is after i click and destroy the game object, the new one will instantiate on a different way point. i have search for ways to do this but i'm stuck, and any advice or idea would be much appreciated.

Code (CSharp):

1. public class ClickAndDestroy : MonoBehaviour
2. {
3.     void Update()
4.     {
5.         DestroyBall();
6.     }
7.     void DestroyBall()
8.     {
9.         if (Input.GetMouseButtonDown(0))
10.         {
11.             RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);
12.             if (hit.collider != null)
13.             {
14.                 if (hit.collider.gameObject == gameObject)
15.                 {
16.                     DestroyObject desScript = hit.collider.GetComponent<DestroyObject>();
17.                     BallSpawn ballScript = hit.collider.GetComponent<BallSpawn>();
18.                     if (desScript)
19.                     {
20.                         desScript.Remove();
21.                         if(ballScript)
22.                         {
23.                             ballScript.SpawnItems();
24.                         }
25.                     }
26.                 }
27.                 else if (hit.collider.gameObject != gameObject)
28.                 {
29.                     print("you lose");
30.                 }
31.             }
32.         }
33.     }
34. }

Code (CSharp):

1. public class BallSpawn : MonoBehaviour
2. {
3.     public Transform[] spawnPoints;
4.     public GameObject[] balls;
5.  
6.     void Start()
7.     {
8.         SpawnItems();
9.     }
10.  
11.     void Update()
12.     {
13.        
14.     }
15.  
16.     public void SpawnItems()
17.     {
18.         int spawnIndex = Random.Range(0, spawnPoints.Length);
19.         int spawnObject = Random.Range(0, balls.Length);
20.  
21.         Instantiate(balls[spawnObject], spawnPoints[spawnIndex].position, spawnPoints[spawnIndex].rotation);
22.     }
23. }

 

In your SpawnItems() method, do you use ball prefab, to spawn from?
I suspect, you use existing balls for instantiation, see second script line 21.

Here is one of few way you can do it.
https://docs.unity3d.com/Manual/InstantiatingPrefabs.html
In inspector of InstantiationExample.cs, you just need attach your prefab, in myPrefab field.

 

hi i use the ball prefab to spawn from. the problem i got is that when i click on the ball and destroy it the next one doesn't pop up in the next way point.

 

I suspect issue with random spawn object. Try set it to 0 and see if any results.
