Synchronizing Spawn game object in unity and using Photon pun 2

Question

Working on Multiplayer Game using photon pun 2 in Unity. I am trying to synchronize Box which is spawned when player trigger a function. So i need to synchronize game object for all players.enter image description here

Here is Spawning Codeenter image description here

private void SpawnBox()
{ 
    PhotonNetwork.Instantiate(Path.Combine("PhotonPrefabs" , "PickableCube"), transform.position, Quaternion.identity); 
} 

private void OnTriggerEnter(Collider other) 
{ 
    if (other.CompareTag("Player")) 
    { 
        SpawnBox(); 
    } 
}

I want to synchronize the game object for all players so if any player let the game it should not effect the game objects which are spawned in map . I tried PhotonNetwork instantiate , and also Photon view and photon view transform is applied on the box.

Answer 1

One issue I noticed is that there is no constraint on who runs the Instantiate function.

Imagine there are 2 players total and P1 enters the trigger.
That player enters the collider on each client.
P1 sees them enter and executes Instantiate.
P2 sees them enter and executes Instantiate.

Adding a local player check before spawning the box will prevent each client from instantiating the box.

private void SpawnBox()
{ 
    if (!photonView.isMine) return; // Not our player, don't spawn box

    PhotonNetwork.Instantiate(Path.Combine("PhotonPrefabs" , "PickableCube"), transform.position, Quaternion.identity); 
}
