Adding Multiplayer Support in Unreal Engine 5

In episode 15 of the UE5 game development series, we'll start adding multiplayer support. We'll first look at how network players spawn and customize our PlayerStart assignments. We'll then learn how client and server movement replication works, and add a client to server RPC (Remote Procedure Call) so our movement is replicated.

Your content is hands down the best I have found anywhere ever on unreal! No course or KZbin channel comes anywhere close and I have watched thousands. Your pace is perfect for me and it’s so concise. Thank you so much.

[@varrickWRLCK]

Amazing video - you just saved a massive amount of time for me! Thank you so much!

[@foxtail8974]

I learned more in this 8 minutes than I did 2 years in college...

[@brennonwilliams9181]

Really like your content and the way you structure your episode. Great to see C++ specific - looking forward to the next one!

[@LivelyGeekGames]

Thanks, glad you enjoy it!

[@sqa1824]

Your content is soooo underated also can’t believe how much unreal has changed especially because epic made it

[@K0UK0U]

Incredibly important video. Thnx

[@MacMiggity]

I'm glad I found your channel.

[@LivelyGeekGames]

I'm glad you found it too! :)

About 6 months late on this, but just wanted to say it's very well done. It's amazing how many AAA games don't do a lot of server side validation you mention at the end, so it's already a great video for those wanting to learn how to build software. Just a bit of validation up front will save a lot of heartache later. ;)

[@LivelyGeekGames]

Thanks! I imagine studios have much tighter timelines so they need to cut some corners. I agree it's always good to have some kind of server-side validation, or at least detection with logging.

[@andrewshandle]

@@LivelyGeekGames The problem is, once a game develops a reputation as being a cheat-fest, it can kill it, even games in early access. I used to always tell my developers to think like testers whenever building anything, because whether it was customer/client facing or internal but needed auditing for whatever reason, the first step is figuring out all the bad stuff people can do with the code and make sure it doesn't happen (or at least we can track it). Multiplayer games are about 100 times worse because history has shown that if there is an easy way to cheat or exploit a system, players will do it and they'll do it on day one. ;)

[@PikaDevs]

Really nice content

[@LivelyGeekGames]

Thanks!

[@ruellerz]

Any upcoming blueprint vids? Im announcing location based on multicast with tick but i foresee lags. Have u tried network prediction plugin?

[@kevincantrell6295]

do you have a video explaining setting up for multiple controllers on a multiplayer game?

[@Hope-kf1nl]

Hey man, where's your Patreon? I'm a 29 year old who's career is a full-time cyber security engineer. I've been really itching to start a passion project using UE5, the new Nanite technology that was released has got me inspired to give it a shot. Also your work has really jumpstarted my learning curve. Thank you so much for this content. It's right on the money.

[@LivelyGeekGames]

I'm glad to hear you're finding it useful! I'm in the same situation, just wanting to learn something new outside of my current tech job. Unreal has been really fun to learn, especially with how many areas it is being used these days. I don't have a Patreon since I'm still new to KZbin, but perhaps I'll set one up soon!

Make that 3 of us

Just found ur channel, any ideas on how to start learning c++ for game development, also things I would like to say 1: yes I’m dedicated enough to learn c++(was told it’s hard to learn) with out any other knowledge of of other programming languages, 2:would u possibly do lessons on the channel, 3: I saw documentations on epic having a service for mp(like steam) for cross play,game chat ect ect what do you think about that

[@LivelyGeekGames]

C++ can be a challenge to learn, but it's very doable. I did from a book while in high school, so you don't need any formal training. Also, for most game code you'll write in Unreal, the engine takes care of a lot of things for you (like memory management, threading, networking, etc) so it's even easier. I would first learn the basics of programming and C++ from some tutorials such as: www.cplusplus.com/doc/tutorial/ Once you have the basics down, read through: docs.unrealengine.com/en-US/ProgrammingAndScripting/ProgrammingWithCPP/IntroductionToCPP/ After that, you could start watching though my UE5 series. I explain most of the code being used line-by-line. If you have any specific questions or don't understand some parts just leave a comment and I'll answer them. kzbin.info/aero/PLLIn4osBl0FsKVoxTF0Xi8tvO34XALuNP I don't have plans to do a generic C++ intro since there are probably plenty of those out there already, but perhaps I will in the future. For now I'm focused on explaining the code needed to build the simple game. As for the Epic Online Services to help out with various multiplayer functions, yes, I'm excited to dive into those and add them to the game in future videos. I plan to use it for user authentication, voice chat, and to save user preferences such as key bindings.

[@HesiGrinds]

@@LivelyGeekGames ok thanks, I’ll look in to it

[@BrandonVox]

Do you use EOS in this tut sir?

[@tristankubih]

How can you make this, so that friends can join the server outside of your connection. So with different internet and stuff

[@preston748159263]

Do you think multiplayer is something that needs to be considered early in a project? I want to build a game and would love to not have to worry about networking and stuff until later when I want to add the multiplayer aspect.

[@LivelyGeekGames]

Yes, for sure. For some things like level design with static assets it doesn't matter, but any form of interactivity certainly does. Whether it be opening a door, player inventory, pawn movement, etc. They all need to happen authoritatively on the server with possible client-side prediction and/or replication to other clients.

[@preston748159263]

@@LivelyGeekGames This is fascinating and sounds like a major learning curve. Thanks!

[@antipainK]

Is the process the same if you want to implement Steam API?

[@alexischarpy4160]

Hello dude! You learnt me a lot in a few minutes... Could you please help me on were to find the cpp to code C++ ? I was able to do everything you made out of UE5, but can't find the cpp to add RPC"s... Thanks mate ! (Win a new sub ;) )

[@1UniverseGames]

Do I need to pay for servers for multi player game mode? Or UE5 can do such things:)

[@CreativelyBad]

When using git for your game do you pay for more storage? Just curious because I am looking to use git with my ue projects and can’t due to storage limitations

[@wesss9353]

Can someone send this video to Bethesda?

[@anonanon2031]

I don't understand. How in GTA can people warp around with their mods when the server can check if a move is legal?

[@ThankYou_AV]

Blueprint please

[@thewellingtoneduardo]

it seems create a mmorpg on my own is too much 😖
