Resolved Mirror Button Button Conversion Issues in Online Scene

Hello all-

I have been using Unity Mirror to make an online project. I am currently trying to replace the NetworkManagerHUD with my own buttons. My technique is creating a new button, adding a new OnClick function, and setting the NetworkManager object into the function. Then I make the function StartHost(), for example.
This works OKAY in the lobby, but there is no way to make this work in the online mode with a "Leave" button. This seems to be because when you have the NetworkManager in the DontDestroyOnLoad category, the leave button can't register the NetworkManager. The function, therefore, is not called and the button does not work. My solution was disabling the NetworkManager from being in the DontDestroyOnLoad category. This also doesn't fully solve my problem. When you run it again, you ARE transported back to the lobby when you click the leave button, but this time you get these messages if you try to reconnect:
Is it not transporting fully? Here is what my online scene's OnClick() looks like:

Here is how I set my NetworkManager:

What do I try? I am sincerely confused!

Thanks in advance!

 

I'd avoid adding the NetworkManager directly into the OnClick callback as you won't be able to do the same in the online scene. As a simple solution have another GameObject in each scene to handle the starting and stopping of the network:

Code (CSharp):

1. public class OfflineSceneController : MonoBehaviour
2. {
3.     public void OnClickNetworkStart()
4.     {
5.         if (!ParrelSync.ClonesManager.IsClone())
6.         {
7.             NetworkManager.singleton.StartHost();
8.         }
9.         else
10.         {
11.             NetworkManager.singleton.StartClient();
12.         }
13.     }
14. }

Code (CSharp):

1. public class OnlineSceneController : MonoBehaviour
2. {
3.     public void OnClickNetworkStop()
4.     {
5.         if (!ParrelSync.ClonesManager.IsClone())
6.         {
7.             NetworkManager.singleton.StopHost();
8.         }
9.         else
10.         {
11.             NetworkManager.singleton.StopClient();
12.         }
13.     }
14. }

 

Do I have to include the "ParrelSync" part of the script? I don't use Parrel for testing but I guess I could download it.

 

You don't have to include it, but you'll likely be using it at some point. You don't need to use it here if you're using separate buttons for host and client.

 

so then how would I rewrite the script to make it work without the ParrelSync section? I am using separate Host/Client buttons...

 

There's not much to change, just create a method for each button. For example:

Code (CSharp):

1.     public void OnClickStartHost()
2.     {
3.         NetworkManager.singleton.StartHost();
4.     }

 

I tried you method. It kind of worked, but there is still a weird bug. Here is my script:
Here is the leave button's inspector:

Here is how the cycle runs (and fails):
As you can see, when I am teleported back to the Lobby, the Host and Client buttons do not work anymore. Here are the warnings I get on clicking them:

What steps do I take next? Am I misunderstanding something? Do I need to terminate the server in my script?

All images: (NOT IN ORDER)

 

I can't see enough to tell you, the hud suggests the server is stopping but the host's client isn't disconnecting, I don't know why that would be. Try re-adding the NetworkManager to the offline scene again to get back to its default settings.

All you should need at this point is a button in your offline scene to StartHost and a button in your online scene to StopHost.

 

You were correct. I re-made the scenes and your solution works!

I have another question (I'm a pain, I know). How do I make my UI so that when someone joins as a host, they can only click the stop Host button, and as a client they can only click the stop client button.

 

You can use the above ParrelSync example to share the same button, that way the original project is the host and the ParrelSync clone projects are the clients. That will suffice with testing for now, you'll need more elaborate connection scenes in builds anyway.

By the way there's some networking and Mirror video's on this channel that are worth watching: https://www.youtube.com/@ShrineApp/videos

 

Cool! Thanks for your help! I think this thread is RESOLVED.
