I have an object what I use only in one scene, so I do not want to make it prefab. This object has network identity, and a script which is increasing a syncvar integer in the update method. When the game starts this object got disable because the server is not running. When I start hosting the server this object got enabled. Everything fine is this point but when a client is joining this object is still disabled in the client and not synchronized.
If I am right it is because the objects are not connected to each other. how and I solve it without making this object a prefab and just spawn it?
How can I spawn objects without a player prefab with authority on the server (it would be a singleton service object)?
NetworkIdentities have to be spawned. If it is already in your scene you can enforce it to be spawned by using
NetworkServer.SpawnObjects();
Also you can spawn any prefab you defined in the NetworkManager. Look for the Registered Spawnable Prefabs Array. To spawn a registered prefab you can use
NetworkServer.Spawn();
For example spawn a registered prefab on the server using a Command:
[Command]
public void CmdSpawnGameObject()
{
var spawnObject = Instantiate(prefab, Vector3.zero, Quaternion.identity);
NetworkServer.Spawn(spawnObject, connectionToClient);
}
How can I spawn objects without a player prefab with authority on the server (it would be a singleton service object)?
You can't. You have to have a playerPrefab spawned and you have to have authority. But you can also hand over authority using
identity.AssignClientAuthority(conn);
