Hello .. I am building 4 players online game on Unity .. I have figured to spawn two players only in different places .. but I need to spawn another two players in another different places .. PLEASE HELP

here is my C-Sharp code:

void SpawnPlayer()

{
if (PhotonNetwork.IsMasterClient) { playerPrefab = PhotonNetwork.Instantiate(playerPrefab.name, new Vector3(0, -800, -315), Quaternion.identity);
}

else
if (!PhotonNetwork.IsMasterClient)
{
playerPrefab = PhotonNetwork.Instantiate(playerPrefab.name, new Vector3(0, -800, 315), Quaternion.identity);
}
}
