How do I properly adjust spawned network prefabs

    Hello all,
    Here's my problem: I spawn a network object from a prefab, it has some network behaviours with network variables. Upon spawning the prefab I want to adjust values of the network variables for this particular instance that I just spawned.
    I tried setting values before calling NetworkObject.Spawn() - this gives me a warning:

    NetworkVariable is written to, but doesn't know its NetworkBehaviour yet. Are you modifying a NetworkVariable before the NetworkObject is spawned?

    Ok then, I decided to set the values of network variables after the NetworkObject.Spawn() call. This works, but on the clients (when the spawned object gets spawned there) I get a few frames of invalid values in my network variables. So the question - is there a way to adjust a network object upon spawning before syncing it to the clients?

    A solution I can think of is to spawn the networkObject only on server and hidden from clients, change the values and then show it to the clients

    Hi @YurySedyakin , there's an example on how to initialize clients upon spawn here, using OnNetworkSpawn. It's not exactly what you're asking for, but should give you an idea of the workflow.

    As a side note:

    NetworkVariable is written to, but doesn't know its NetworkBehaviour yet. Are you modifying a NetworkVariable before the NetworkObject is spawned?

    is an unharmful error, and if your purpose is to modify a variable before the object spawns, that's the right workflow!
