This video will teach you how you can create a basic server hosting and joining system

Hello @kibibytecompany, I was wondering for all of your games that you've used Peer-To-Peer is this as far as you need to go involving BP's and any code? Or when creating the game would you need to implement them into any BPs I.E. a door that uses an interact key to open and close? I had the issue where only the client could see the door opening but on the server hosts screen it was shut the entire time. So even though the client saw it opened they couldn't walk through because the server hosts saw it closed still.

The video only shows how to create the basic system for connecting with other players. You will need to replicate everything you want to be replicated. So yes, you will need to code.

If you have troubles with find sessions advanced, you need to add exclusion for local network in windows firewall.

@kibibytecompany 2 ай бұрын

That’s good advice if it helps. Personally, I haven’t had such problems with windows firewall.

Can you elaborate what exclusions should be added? Please and thank you :)

A question. I created a similar host/join sessions but when I tried it with a friend from a different country the host would open the level but the client could not find it. Is it possible to make a multiplayer without the epic online services? I would love a tutorial on this topic if you dont already have one

@kibibytecompany 11 ай бұрын

The video only shows how to do it with Steam. If you want to use the Epic Online Subsystem there are other ways you need to follow.

I'm still having an issue getting this to work. Clicking "host" allows the game to run, but on the other instance, clicking "join" does nothing. The button greys out, but it doesn't join when in the editor. I followed the exact video instructions twice (created 2 separate projects) and got the same result. It's unlikely I'd make the exact same mistake twice. I saw a comment that'd you'd be uploading a video about some "fix" you found in the next few days? Is that still a thing?

By default, would this allow people to open the steam overlay and join/invite people to their lobbies through clicking those respective buttons, or does extra work need to be done? I don't currently have an AppID so I have no way to test this.

You can use the AppID 480 for testing. This works right away. But some viewers reported having issues in UE5.3

@splurpy_ for testing you can easily create 2 instances in your editor on PIE and connect to each other without Steam like shown in the video. If that works Steam should also work.

Hello! Thank you for the very quick and clear tutorial. I tried it and I have my project running on 2 different machines with 2 different steam accounts. I can invite a friend, they can join, and I can see in the log that the P2P connection opens. However, it then keeps trying to finish diagnostics on the client before timing out. Also, client does not spawn in on the 'host's' end. Would you happen to know how to fix this?

@@kibibytecompany I implented the plugin as you described and am trying to join a different session. Now when I create and join a session in the viewport with 2 players it works just fine, but I am currently trying to join a Session on a different PC. Creating a Standalone Session with one Steam Account works fine, but as soon as I try to join the session with another Steam account the System loads for a while, then start the Default Map from Project Settings. I have now tried to find the error, and Event NetworkError indeed shows a "Connection Timeout" Error, meaning the Find Advanced Session succeeds, finds a Session, then tries to join the session, succeeds, but in the proceess of joining, seems to timeout for some reason, then starts the Default Map. Essentially I am asking if you have any idea, why the Join Session Function might time out. I am struggling to find a solution.

@kibibytecompany 10 ай бұрын

Hello and thank you for explaining. This can have multiple potential causes. You are connected to different steam servers (e.g. EU and US), The internet connection isn’t stable, you have wrong server creation settings. You can also declare what should happen when someone timed out in the games instance. I never encountered a timeout when traveling that’s why I can’t help you that much. Other reasons could be that just something else is overloading some unreal engine system thus it has not enough resources to keep a stable connection.

Yes, but you will also need to host your own server for that. That is why I use peer to peer connection in this video, as you don't need a server for that. It always depends on what game you are trying to create. If it is a competitive multiplayer game, then you will need a dedicated server. If not and it is just a calm game to play with some friends, then you can use peer to peer connections
