Game Development How to Make a Video Game Pickups Spawn Pickups Randomly

Why are all the flies disappearing?

Here is the code to the fly spawner and fly pickup, I just want to know if I did everything correctly because for some reason whenever I try to test the game out, the flies disappear and they don't respawn:

FlySpawner.cs using System.Collections; using System.Collections.Generic; using UnityEngine;

public class FlySpawner : MonoBehaviour {

[SerializeField]
private GameObject flyPrefab;

[SerializeField]
private int totalFlyMinimum = 12;

private float spawnArea = 25f;

public static int totalFlies;

// Use this for initialization
void Start () {
    totalFlies = 0;
}

// Update is called once per frame
void Update () {

    // While the total number of flies is less than the minimum...
    while(totalFlies < totalFlyMinimum) {

        // ...then increment the total number of flies...
        totalFlies++;

        // ...create a random position for a fly...
        float positionX = Random.Range(-spawnArea, spawnArea);
        float positionZ = Random.Range(-spawnArea, spawnArea);

        Vector3 flyPosition = new Vector3(positionX, 2f, positionZ);

        // ...and create a new fly.
        Instantiate(flyPrefab, flyPosition, Quaternion.identity);
    }
}

} FlyPickup.cs using System.Collections; using System.Collections.Generic; using UnityEngine;

public class FlyPickup : MonoBehaviour {

[SerializeField]
private GameObject pickupPrefab;

void OnTriggerEnter (Collider other) {

    // If the Collider other is tagged with "Player"...
    if (other.CompareTag ("Player")) {

        // ...add the pickup particles...
        Instantiate(pickupPrefab, transform.position, Quaternion.identity);

        // ...decrement the total number of flies...
        FlySpawner.totalFlies--;

        Destroy (gameObject);
    }
}

}

I have the same problem and I don't know why...

It's not your code . .You likely have the pickupParticlesDestruction script attached to your Fly preFab.
