That was the single clearest explanation of the UE networking basics I've seen. Great job!

[@mapleint997]

I'd most definitely love a part 2, is the resource on it's own extensive enough?

[@reubs]

If you're a beginner, grab a coffee and in 30 minutes I promise you'll have a much better understanding of networking in UE4.

I feel like i understand it well, but cant implement it. I have a project, its still small but i want it to be a Multiplayer Game. Now i have to change lots of things. My Problem is for example that i have a Blueprint Widget which shows my Health as Number, dont know how to replicate that, it turns my Health float into a string or name and just sets it on screen. But every client shares the number.

[@leonidkhamadakov7778]

Thank you!

[@squarerootof2]

Hi Reuben, where's the link for the Network Compendium? BTW. great channel and excellent tutorials. Edit: Thanks, I found it at the link on the screen at 1:30. I was looking for it in the description.

[@chadgtr34]

can you discuss which method is best for Sim Racing Multiplayer? where cars will be hitting each other and crash , multiplayer Nascar.

[@JafsBox]

Wish I had found this when I started out, it would've saved me so many headaches!

[@snappydue1616]

Yesss! I need more of this! :) I've been trying to do a simple 1v1 sniper game, and I have a hard time keeping information that are in the PlayerState when the client travel. Since everything is destroyed and recreated when traveling, I don't know how to store that information on the server and then pass it back to the client. (Array of PlayerState? Save on file then reload? Save on the server?) Anyway, thanks for that video, it was a great revision!

[@CENSOR_1337]

This is a fantastic content, We absolutely need part 2 :D

[@II-er7gj]

Please make Part 2 for Unreal Networking! Awesome!!!

[@MrPstewart84]

Best network tutorial for UE I've seen and I've been searching. Well done and thank you!

[@fictionalgaming912]

30 minutes with it on loop....thats going to be the best way to memorize this topic before actually implementing it.

[@jakemillian8758]

This is the best one to explain how the network frame of UE4 works, amazing video, thank you man!!!

[@20cnVision]

This makes it seem so much less intimidating. Thanks a lot, amazing video.

[@wiglord]

thanks for this, for me the clarity on replicating variables was what I was missing out on the past few weeks. Now I know the server rules all changes I can fix up some of the issues in my replication events :)

[@TechnoVikingOz]

talk more about replication. specifically, flow of join and leaving games, and traveling between servers. Bonus points for dealing with an end game state (show the game scores for a little while), before traveling to the next map.

[@axonpark]

I think I am missing the hundred plus page resource you mentioned at the start of the video

[@hahugo9334]

thanks，clearly explained the basics of UE networking

[@SuperMontana2008]

You are unstoppable 👍

Thanks man 8)

[@avtaras]

Super underrated. Best video I’ve ever seen on replication.

[@alexmomot6268]

Thx a lot for such amazing tutorial with excellently chosen strategy to explain the replication basics in UE4. Thanks again.

[@da_cat]

Nice explanations ... now i am more confident in making a multiplayer game, i think i can pull it off.

[@adamodimattia]

I've been through some of your videos and they are really awesome so I've become a patron to be able to follow along survival game course. I've been learning and using Unity for the past two years and I'm using Unity at work and so and I wanted to finally check out Unreal in my spare time also because C++ is my favorite language. I'm just beginning with Unreal but my thoughts for now are that if I were to develop my own game I would probably prefer to do it on Unreal.

thanks thats really simple explained.!

[@Ashborne907]

THANK YOU SO MUCH! Been searching the web for hours before I found this video and it helped me a ton! Finally understood what the hell is going on. :D

[@swrcPATCH]

You should have explained what RPC stands for so that people who do not know already will understand what it is.

[@Carrotgold]

Your channel content looks amazing 🙃

[@vectonaut1503]

Hey man this is golden. I'm currently going through your BR course and this is such a good overview for how replication works as a whole.

[@jacckmgr2763]

Part 2 please

[@luckypratama5295]

Thank you very much for this! I’ve seen a lot of videos about replication but this is the one that provides the easiest explanation of all. I still don’t quite understand how you can actually “play” the game over a network. I’ve made a simple 3-player level with replication but all it does is launching 3 windows, one for each player. Could you give me a direction on what do I need to do? Do i have to set up a listen server or something?

[@axonpark]

Superb!

[@unrealmagedev]

Amazing, thank you.

[@bad-dev3135]

amazing video, i would listen to a lot more on that topic if you would upload.

[@DeeOdzta]

Nice one Reuben! - reposted ..and yeah please talk about networking for hours thanks for all your knowledge you share :)

[@ireheartstudios]

Can you do an update video of changes between UE4 and UE5?

[@TheJacksonblair]

You legend this is great

[@zytron615]

What about client prediction and smoothing, is there any ressource on how to add that?

[@emptybruh]

So basically everything we want to happen on a multiplayer game must be hooked up so server does it instead? For example, a game that would be fully multiplayer, each and every function would be called server side?

[@ElementalCode]

back to the example of the disappearing cupcake: if we are authority: should we still call the server RPC or should we realize that we are the server and just do stuff? Thanks a lot for this videos. Good tutorials that use both c++ and blueprints are hard to find

[@szlobi2276]

he mentions using the switch has authority node. that is what you need. If you have authority (server) you do your thing, and if you are remote (client) just call a server RCP

[@mobildisko579]

16:40 When the x key is pressed, Instead of using "run on server", couldn't we use "switch has authority"?

[@henkmassink6713]

Superb comprehensive tutorial. What I find the most difficult part is to compile the server en client and the get this working online, for example on a linux or windows vps. Until now I am not able to get this working. And, to my knowledge, there is now proper information / tutorials te be found. I am following the Flopperam tutorials now, this looks promising, but is based on AWS. So are you covering the compiling to dedicated server and get it running on a server in your course?

[@TechnoVikingOz]

hi henk, the survival game course's last video is around 40min of getting the game compiled, cooked, and setup and deployed with a linux server and windows clients.

[@jensenraylight8011]

btw, why you build your own infrastructure, if you can use AWS?, i mean AWS are more scalable

[@henkmassink6713]

@@TechnoVikingOz I have access to survival game now.

[@henkmassink6713]

@@jensenraylight8011 Could be, but I find it extremely difficult to understand. But hopefully the tutorials of Flopperam wil guide me.

[@mattg6550]

In a real game should the server be one of the players, or should it be some sort of manager object that players can't interact with? In this demo, it seems you have 3 clients and a server but all are characters in the scene.

[@PhoebeJCPSkunccMDsImagitorium]

When you tick on 'replicate,' how many lines of code is that adding to the blueprint? I wonder if just flipping everything Unreal Engine has to 'on' might be less efficient than getting into the C++ weeds and coding it ourselves

[@squarerootof2]

You have o chick all the chickboxes.

[@glassbunnyy]

[@thechronicgrump3906]

So I need to use an OnRep if I’m going to be replicating to server?

[@sharvanpoonia6797]

Can u make your course available on udemy

[@timos9416]

can you make a video about how your IDE is working as intened? all that code completion stuff only appears after a certain time on my system - somehow your library looks more on point :D

[@AuraGamesIn]

Is this work same way in mobile

[@KornelSevinger-pb7nw]

chickbox thanks for the tutorial btw.

[@callmedeno]

Is there still no integrated solution to networked physics in the unreal engine? I remember they bought psyonix who made rocket league and was thinking 'hmm maybe they could bring that tech into the engine for everyone'... but as far as I know it hasn't happened

[@Lord.Caridos]

hmm, can you using cloud gaming for the networking?

[@hassanalhobail8084]

17:38 But what if I want to hide everyone's cupcake? What does it mean that I'm using this "blueprint" in particular?

[@nickgeiserr]

Hi this is late but you forgot to leave that one long sheet of networking info! If you see this could you link me that? Would love to read it
