is there a way to make it so that they can spawn at random times 1 by 1

public class newSpawner : MonoBehaviour

void Start()

    Vector3 center = transform.position;

        Quaternion rot = Quaternion.FromToRotation(Vector3.forward, center - pos);

    }
}

Vector3 RandomCircle(Vector3 center, float radius)
{
    float value; 
    value = Random.value * 360;
    Vector3 pos;
    pos.x = center.x + radius * Mathf.Sin(value * Mathf.Deg2Rad);
    value = Random.value * 360;
    pos.y = center.y + radius * Mathf.Cos(value * Mathf.Deg2Rad);
    value = Random.value * 360;
    pos.z = center.z + radius * Mathf.Sin(value * Mathf.Deg2Rad); 
    return pos;
}

public float maxSpawnDelay = 3f; //Max delay until next spawn in seconds
public float minSpawnDelay = 1f; //Min delay until next spawn in seconds

private bool _spawning;   //Determine if spawn sequence is active
private float _lastSpawn;  //Last time a prefab spawned
private float _curDelay;     //Current delay in seconds until a spawn should occur
private int _curIndex;      //Amount of objects spawned

void Start(){
_curDelay = Random.Range( minSpawnDelay, maxSpawnDelay ); //Get a new delay for next spawn
_lastSpawn = Time.time;  //Cache time when begun

_spawning = true;   //Starts the spawn sequence
}
//Progress the spawn sequence, should be called every time the prefab is instantiated
void OnSpawned() {
_curIndex++;
_lastSpawn = Time.time;
_curDelay = Random.Range( minSpawnDelay, maxSpawnDelay );

}

void Update() {
if( !_spawning ) {
return;  //Stop if spawn sequence is not active
}

if( Time.time - _lastSpawn >= _curDelay ) { //When enough time has passed spawn a new prefab instance
Vector3 pos = RandomCircle( transform.position, 20f );
Quaternion rot = Quaternion.FromToRotation( Vector3.forward, center - pos);
Instantiate( prefab, pos, rot );
OnSpawned();
}

if( _curIndex >= numObjects ) {
_spawning = false;   //Stop spawn sequence when the target number of objects has been instantiated
}
}

One, of multiple ways to achieve this. :slight_smile:
