Spawn NetworkObject and change sprite at runtime

[davidegalifi]

I’m a super noob with Game Development and with Unity and I’ve been playing with networking but I think there’s something I’m missing
The idea is really simple. I’m instantiating a GameObject at runtime and its color depends on some variables loaded at runtime but for simplicity let’s supposed I want to set it as red at runtime.

My GameManager Start() method looks like this

 var prefab = Instantiate(Prefab);

var prefabBehaviour = prefab.GetComponent<MyBehaviour>();
prefabBehaviour.GetComponent<SpriteRenderer>().color = Color.red;

prefabBehaviour.NetworkObject.Spawn();

The result is that the object is instantiated as red on the server but on client it’s spawned with the default color.

How would I achieve something like this?

I have not tested it, but maybe it will help

using UnityEngine;
using Photon.Pun;

public class GameManager : MonoBehaviourPunCallbacks
{
    public GameObject Prefab;

    void Start()
    {
        // Instantiate the prefab
        var prefab = Instantiate(Prefab);

        // Set color on the server
        var prefabBehaviour = prefab.GetComponent<MyBehaviour>();
        prefabBehaviour.GetComponent<SpriteRenderer>().color = Color.red;

        // Check if the current instance is the master client (server)
        if (PhotonNetwork.IsMasterClient)
        {
            // If yes, spawn the object and synchronize color
            prefabBehaviour.NetworkObject.Spawn();
            photonView.RPC("SetObjectColor", RpcTarget.OthersBuffered, Color.red);
        }
    }

    [PunRPC]
    void SetObjectColor(Color color)
    {
        // This method will be called on clients to set the color
        var prefab = Instantiate(Prefab);
        var prefabBehaviour = prefab.GetComponent<MyBehaviour>();
        prefabBehaviour.GetComponent<SpriteRenderer>().color = color;
    }
}

I’m not sure about this Photon library but I’m fairly sure you can’t instantiate a game object on the client

Do you know how multiplayer works?

No I don’t. I’ll give it a try
