Spawn in a fix position 2D Game - unity3d

Question

I am trying to do a multiplayer game and I have a problem with spawning prefabs. I want this prefabs to be spawn in 2 fix position but I don't understand why my script doesn't work because when I start the game the objects are spawn in one position. I created an empty game object( I named it Spawner and added the script) and added 2 game objects ( Position1 , Position2 ) as Childs. The prefab is spawn in the position of the Spawner and not position 1 and 2 .
Here is the script I used. Also do I have to add to it PhotonView and Photon Transform ? and something with PunRPC?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class SpawnPosition : MonoBehaviour
{
public GameObject[] powersPrefab;
public Transform[] points;
public float beat= (60/130)*2;
private float timer;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
if (timer > beat)
{
GameObject powers = Instantiate(powersPrefab[Random.Range(0, 2)]);
powers.transform.localPosition = Vector2.zero;
timer -= beat;
}
timer += Time.deltaTime;
}
}

Answer 1

You always set
powers.transform.localPosition = Vector2.zero
The object is instantiated on root level without a parent this equals setting its absolute position .... you always set it to the Unity origin.
You probably wanted to spawn it at the position of on of the elements in points like e.g.:
var powers = Instantiate(
powersPrefab[Random.Range(0, powersPrefab.Length)],
points[Random.Range(0, points.Length)].position,
Quaternion.identity
);
see Instantiate for available overloads.
However as you also state this is for multiplayer so you shouldn't use Instantiate at all since this only spawns this object on this client but not on others. You should probably rather make sure that this spawner is only running on one of your clients and use PhotonNetwork.Instantiate instead.
Something like e.g.
public class SpawnPosition : MonoBehaviour
{
public GameObject[] powersPrefab;
public Transform[] points;
public float beat= (60/130)*2;
private float timer;
// Update is called once per frame
void Update()
{
// only run this if you are the master client
if(!PhotonNetwork.isMasterClient) return;
if (timer > beat)
{
// spawn the prefab object over network
// Note: This requires you to also reference the prefabs in Photon as spawnable object
Instantiate(
powersPrefab[Random.Range(0, 2)].name,
points[Random.Range(0, points.Length)].position,
Quaternion.identity,
0
);
timer -= beat;
}
timer += Time.deltaTime;
}
}

Answer 2

This should work
void Update() {
if (timer > beat) {
GameObject powers = Instantiate(powersPrefab[Random.Range(0, 2)]);
powers.transform.localPosition = points[Random.Range(0, points.Length)].position;
timer -= beat;
}
timer += Time.deltaTime;
}
}
You are not assigning right position, and since they are parentless power.transform.position = Vector2.zero means that power's global position would always 0,0,0. So you must assign it as I wrote above, and it's also randomized.
