subscribe for cute lil snakes - watch the next part here kzitem.info/news/bejne/p6CFwKaJiX6QYI4 Wishlist my new game BUMBI on Steam! store.steampowered.com/app/2862470/BUMBI/ small bug fix - in PlayerLength OnNetworkSpawn() after subscribing to the length changed event, put: // If there was another player already in the match, the beginning tails of them won't be updated. These lines check the length of the snake and spawn the tails of the other clients accordingly. if (IsOwner) return; for (int i = 0; i < length.Value - 1; ++i) InstantiateTail(); Also before spawning the Food object make sure to do if (!obj.IsSpawned) obj.Spawn(true); And when despawning you can just do if (NetworkObject.IsSpawned) NetworkObject.Despawn();, and not Destroy it.

You can add this at any time, it’s just so that when a new player joins it can spawn the tails of the other players if they had already grown in length. The section before 1:10:03

Not sure if mentioned in the comments yet but I just finished the object pool section and Unity has already updated the script for object pooling on their doc page. You no longer have to create the non pooled object variable as they replaced the queue with an object pool object which keeps track of how many active and inactive objects are in the scene. No fault to the creator of the video as she is doing a wonderful job teaching, just we all know unfortunately unity updates stuff every week it seems haha. But just wanted to point that out if anyone is having any issues following on the object pool section.

In Netcode GameObjects version 1.3.1 they added this: Network prefabs are now stored in a ScriptableObject that can be shared between NetworkManagers, and have been exposed for public access. By default, a Default Prefabs List is created that contains all NetworkObject prefabs in the project, and new NetworkManagers will default to using that unless that option is turned off in the Netcode for GameObjects settings. Existing NetworkManagers will maintain their existing lists, which can be migrated to the new format via a button in their inspector. (#2322) Does this mean that I no longer need to add my prefab to the Network Prefabs List, because as soon as I assign the Network Object it is added to the default List? I updated mid project and now I can't add stuff to the list... :(

My newb guess would be something along the lines of being in a list and needing to be called from the list now instead of just spawning, but I am so new to this I won't find the answer for at least another month or two after my knowledge catches up... to this one little problem. :D

On the other clients none of these are destroyed ! Same on the server. There is just dead bodies all over ?!?:) * & since the tails were collapsing over each other when the head stops, i changed the tail update method, private void Update() { deltaPos = followTransform.position - transform.position; deltaPos.z = 0f; if (deltaPos.magnitude < distance) return; transform.position += deltaPos * Time.deltaTime * moveStep; transform.up = deltaPos.normalized; // Added 'legs' to each tail-segment needed this transform .up }

But net code does not seem to work with addressable scene. Any advice? I am thinking two options : 1) Use RPC to manually load the addressable scene on all clients 2) Make all the contents of the scene an addressable prefab and then include the empty scene in build settings which can be loaded through netcode. Then instantiate the adressable when the scene is loaded by netcode. Thanks in advance 😃

@@samyam oh! But even with Client-Auth set up I’m using ParallelSync and Input System keeps switching the active control scheme on me. It doesn’t want both players using the same control scheme for whatever reason

The speed might be the lag between the client and host and not related to the input system. As for Parallel Sync I haven’t tried in depth with the input system, I know I was having issues with it and determining the mouse position. Can be a silly workaround but maybe you can check if the window is currently active (I explained in the video) and perhaps disable the input on one while you test in the other. Or maybe you can make two control schemes of the same controls, and have each player have a different control scheme once they spawn in. And feel free to join our Discord you can ask in the help chat as well.

Haha I added the active window check to my project after watching you do it 😅 The scheme idea is a good one and will totally work for my project because it’s a max of 2 players. Thanks for the suggestion!

You show a shooter, but would you not use photon for a shooter?

Solution: In the project file, right click, Netcode, make the NetworkPrefabList SO, put your GO there, and put this SO on the Network Manager

I hope you make video on Client Side Prediction, there is no tutorial for that for NGO.

Good course. I am following it and I hope to learn to create some multiplayer game. To develop multiplayer games like this for Android and Apple, do you think a Mac Mini M2 with 8gb of RAM can be enough? or would it have to have 16gb of ram? Greetings.

Hey Samyam! Was wondering if you've used any of the Photon tools before? (apologies if you mentioned it in the video and I missed it) I've been using "Photon Unity Networking 2" for a long time but seeing the activity around other devs and Unity Netcode, my interest is piqued. Is there a particular reason you chose this solution over Photon or any other? Thank in advance!

I tried Photon once years ago but I haven't tried it recently!

I have a slight problem with prefabs reference to themselves. After Instantiating reference changes to the instance of the prefab. So some pooled object can’t return himself to the pool because it has different prefab reference than the one that stored in NetworkObjectPool. What can we do with that? Change the key in ObjectPool to string?

How is the movement done using the new input system? how does the input manager change when doing it multiplayer from doing it single player?

Great video. This was the best explanation of NGO. I am however having some really silly problems with just the basic client connect and host connect calls. Initially I had the buttons in my game scene, but the client connecting duplicated the scene which created a scene that wasn’t responding to game logic over the top of the actual scene that seemingly was… I then took the client connect and host connect buttons and put them on the title screen, so the host connect just calls and then loads the game scene, the client does the same, and they join the game scene, however the host doesn’t think it’s the host! Network manager says the main unity editor is the host, but isHost or isServer isn’t working as intended now… has anyone come across either problem? Thanks!

I don't understand why there is a seperate script lying around in the documentation (ClientNetworkTransform) - instead of including it as a boolean flag in the NetworkTransform or whatever? I am totally confused by this

This seems like a lot, and it's very manageable on a low scale. But, I have to wonder how you'd manage this on a big game with many features. I would get lost trying to find the code to edit a feature, or implement a new feature with existing code on a big game.
