UNET Scene Objects not Spawning w/ Custom NetworkManager

5.2.2f1
TLDR
Don't EVER call Awake() in a custom NetworkManager!


So after a lot of testing I think I finally tracked down the source of my problems. If you have a custom Network Manager that inherits from NetworkManager it appears to override NetworkManager's base initialization if you call your own initialization during Awake(). This causes things like the NetworkManager.singleton not to be set, and also causes SceneObjects not to be "spawned" when a scene is loaded. Calling Awake() in a NetworkManager child doesn't cause any warnings and the NetworkManager.Awake() method is not protected/public so it can't be called by the child... so this means you can't use Awake(). This post is just a heads up for anybody having the problem (it took me a long time to track it down!).

Here's example code that appears ruin the NetworkManager.

Code (csharp):

1.  
2. public class TestNetworkManager : NetworkManager
3. {
4.     private void Awake()
5.     {
6.         //This causes NetworkManager.Awake() not to be called, and doesn't initialize properly causing very strange behaviors...
7.     }
8. }
9.  

Keywords
Inherit NetworkManager scene object not spawned enabled disabled singleton Awake initialize

 

Edit: It appears calling Awake() causes 3 bugs.
-NetworkManager.singleton not being set
-SceneObjects not spawning (NetworkServer.SpawnObjects() isn't automatically called)
-NetworkServer.OnServerSceneChanged() does not get called

 

Please submit this bug, I believe I ran into this on the weekend and it's been causing me huge headaches! Nice find!

 

Looks like it's bug reported and going to be fixed in 5.3.0
Issue #: 735015

Argh I'm on 5.2.3 and just hit this. Thanks!

 

Ran into the same problem in 5.3.4

 

I have custom network manager but i didn't use Awake event in my custom class but still getting the problem that my network identity object are disabled. Can anyone help?

 

I made my custom network manager but i did n't use or call awake event but still i am getting the problem that my additive scene loaded object are disable. The loaded scene object contains network identity. why i am getting this problem?

 

@MFKJ u fixed this problem yet? ..i also have it now.

 

I found out the hard way that if you do a

Code (CSharp):

1. public override void OnServerConnect(NetworkConnection conn)
2. {
3. //your code
4. }

The player prefaf is also not spawned. This does not apply to OnStartHost, OnStartClient, OnClientDisconnect, OnServerConnect or OnServerDisconnect. Only OnServerConnect. Weird.

 

2018.1.9f2 the bug still exist
funny aint it?

 

UNET seems more or less abandoned at this point. I've moved over to Steamworks.NET and had a lot better time (If you plan on using Steam anyhow).
