1 year ago @fernando-cortez With in-scene placed NetworkObjects, you can use the awake method to accomplish this type of functionality.
using System;
using Unity.Netcode;
using UnityEngine;
public class ServerIngredient : ServerObjectWithIngredientType
{
}
public enum IngredientType
{
Red,
Blue,
Purple,
MAX // should be always last
}
public class ServerObjectWithIngredientType : NetworkBehaviour
{
// NOTE: this is a workaround on an issue NGO-side. NetworkVariables should be able to be set pre-spawn.
[SerializeField]
private IngredientType m_StartingIngredientType;
private NetworkVariable<IngredientType> m_CurrentIngredientType;
public event Action IngredientDespawned;
private void Awake()
{
m_CurrentIngredientType = new NetworkVariable<IngredientType>(m_StartingIngredientType);
}
public override void OnNetworkSpawn()
{
base.OnNetworkSpawn();
if (!IsServer)
{
enabled = false;
return;
}
Debug.Log($"Current Ingredient Type: {m_CurrentIngredientType.Value}");
}
public override void OnNetworkDespawn()
{
IngredientDespawned?.Invoke();
}
}Replace the ClientDriven bite sample's ServerIngredient file with the above adjustments. It just instantiates the NetworkVariable in Awake based on the m_StartingIngredientType property's value.
The NetworkVariable documentation provides an order of operations table (dynamically spawned vs in-scene placed). For both dynamically spawned and in-scene placed NetworkObjects, you can instantiate a NetworkVariable within the Awake method and assign the initial value based on a serialized property's value.

1 year ago Side note: Since this type of functionality can be achieved in NGO, I am going to mark this as a feature request. I do think we can make an adjustment that would allow you to accomplish this without having to instantiate the NetworkVariable within the Awake method.
Description
One cannot modify NetworkVariables on in-scene placed NetworkObjects. When one does, you get the following warning message:
and the NetworkVariable is reset to the default value.
Reproduce Steps
Actual Outcome
NetworkVariables on in-scene placed NetworkObject was reset.
Expected Outcome
NetworkVariables on in-scene placed NetworkObject should not be reset and should be saved in the scene.
