Customizing Network Visibility

Hi guys,

I need to implement custom network visibility code in my game for a few reasons:

1) enabling/disabling objects instead of spawning and destroying when network visibility changes
2) send updated data about the object to a player when they begin observing it

I can't use the built-in SyncVar or OnSerialize functions, as it does not fit my needs. Ideally, I'd like to send the data along with the packet which re-enables the object on the client.

So far, I created my own Network Proximity Checker, but I cannot find the place where I can override the messages sent. According to the docs, an ObjectHide message is sent to destroy a no longer visible network object, and ObjectSpawn is sent to create it again. Where can I override this behavior and instead of sending ObjectSpawn, send a custom message? I couldn't find this information on Google or the docs.

Thanks!

 

After some dotPeek usage, it actually appears this is not possible. I hope I am wrong about this, though.

NetworkConnection.cs:

Code (CSharp):

1.     internal void AddToVisList(NetworkIdentity uv)
2.     {
3.       this.m_VisList.Add(uv);
4.       NetworkServer.ShowForConnection(uv, this);
5.     }
6.  
7.     internal void RemoveFromVisList(NetworkIdentity uv, bool isDestroyed)
8.     {
9.       this.m_VisList.Remove(uv);
10.       if (isDestroyed)
11.         return;
12.       NetworkServer.HideForConnection(uv, this);
13.     }

NetworkServer.cs:

Code (CSharp):

1.     internal static void ShowForConnection(NetworkIdentity uv, NetworkConnection conn)
2.     {
3.       if (!conn.isReady)
4.         return;
5.       NetworkServer.instance.SendSpawnMessage(uv, conn);
6.     }
7.  
8.     internal static void HideForConnection(NetworkIdentity uv, NetworkConnection conn)
9.     {
10.       conn.Send((short) 13, (MessageBase) new ObjectDestroyMessage()
11.       {
12.         netId = uv.netId
13.       });
14.     }

Anyone have ideas? It's pretty bizarre that we cannot substitute this functionality.
