🎮 UE4/UE5 Multiplayer - Part 4: Multicast & RepNotify

📹 Part 4 of our replication series unlocks limitless potential with Multicast and RepNotify! In this video, we dive deeper about how Unreal Engine's Actor Replication really works as well as introduce ourselves to a variable replication and how combining the power of variable replication with an event driven design can help us build a multiplayer game with proper client-server communication to keep our game in sync!

Hey Bry, I just wanted to say that this video was extremely well crafted and informative. This is such an important part of good game design which I feel is really easy to mess up unless you dive deeply into the theme. Thanks for doing the work for us and showing it in such an instructive way.

[@brynertoma]

Hey Endre, thank you so much for the kind words! You’re absolutely right in your thinking. Multiplayer opens up so many doors for your games yet if done wrong it can completely ruin the experience. I’m glad you enjoyed it. More coming soon.. just waiting for UE5 to come out before I do any more just in case they change all the buttons on us haha 😁

[@avikb]

I really enjoyed this tutorial Thank you!. I wish you continued this series.

[@TheEightshot]

Also, gratz, you are the FIRST every KZbinr i have ever actually rang that bell for :)

[@xuelongmu7265]

Thank you for this incredible tutorial series, I learned a ton. After testing out the code, there are a few corrections that should be made, in my opinion: 1) The FlipFlop on the chest Multicast Toggle Open event should be replaced by a check on IsOpen. It seems that individual clients have their own version of whether they're Flip or Flop, so you can run into syncing issues on the chest opening animation (e.g. Client 1 opens the Multicast + RepNotify chest. Client 2 then walks over, once they enter the relevancy area the chest snaps open. When Client 2 goes to open the chest, it will actually play the opening animation, even though it should be closing. This is because Client 2 was still set to Flip, i.e. Open, when Client 1 had been set to Flop). Using explicit checks on state variables is probably a better idea for multiplayer scenarios than FlipFlop. 2) For the Multicast + RepNotify, there should be an additional Switch Has Authority node before the RN Toggle Open. Only the server should call RepNotify events. If a client tries to, you get the following error: "UNetDriver::ProcessRemoteFunction: No owning connection for actor Chest4..." By using the switch, you can eliminate this error. 3) The chest's Emissive should be set in the OnRep_IsOpen function. That way, the appearance (rotation + glowing detail) of the chest will be consistent across all players. The way it is currently, if Client 1 opens the chest (which turns off the glow), and later Client 2 comes along, Client 2 will see the chest open and glowing, even though the chest shouldn't glow when open. Thanks again BRY for this series, these minor fixes don't detract at all from the overall quality of the explanations and the amazing production value - just wanted to help others who may be trying to integrate multiplayer into their own games!

[@brynertoma]

It's been a while, but I finally got around to fixing all of these lol.. except now 4.25 users can't open the map since it's on 4.26. Also, a lot of new crashes started happening with trying to create a Dynamic Material Instance in the constructor as the client but only for Text components (UE just crashed) - so that's been changed to. I just have to rebuild part 3 now. Thanks for the feedback brother, hopefully all is well. I love your vids btw. Keep it up (you inspired me again)!

[@xuelongmu7265]

[@ThePavilionWeb]

Part 5 was going to be the Holy Grail I have been after, why stop there?, this was great content, come on Bry you tease!

[@solidreactor]

If one is serious about learning the longer videos are better for those reasons you mentioned. I did get the "aha moment" and a good conclusive summary after I saw the chest and the rainbow (repnotify and multicast). I wouldn't had that learning experience if you had chopped this video up into 3-5 bits.... unless I would have binge watch them all but that would just be the same thing in the end :) So keep doing them long enough so that the whole message gets across in one swoop and ONLY divide the videos *IF* they make sense as a standalone module! Your videos are 9/10, one of the absolute best learning vids for learning these abstract contexts in a such a concrete way. Thank you! You have a superb skill and a and unique way of teaching.

[@brynertoma]

Excellent feedback! Thanks a bunch. It seems like everyone is leaning towards the longer videos and having the message delivered / concluded in 1 single video. I will continue to go with what is logical and not worry so much about the time. Your point about binging them all anyway is bang on lol Thanks a bunch for the kind words, it truly means a lot 😊 I'm glad you're enjoying them and I'm glad my crazy ways of illustrating things is actually making sense to everyone, haha 😁

Oh, and YES The longer videos are much better. I'll gladly wait between releases because when it's all said and done, this is just a better way to learn and like you said; doesn't lose momentum.

[@JasonCaylor]

I'll say that this video is as informative as Epic's official video on the same topics, but much more entertaining. This makes the longer videos much more tolerable and keeps the viewer engaged. As long as the (understandably time-consuming) entertainment persists, you are fine keeping the videos longer covering multiple topics.

Man, I love all of your vids (just 4 for now lol). They are so compact so I sometimes have to pause and think hard to understand and resume. I don't mind vids up to 30 mins, but anything longer than 30 mins I tend not to watch, since I know that I am a quiter. I was struggling so much with Multicast and RepNotify, but you got them so well in this video, so thank you so so so much. I hope that you keep posting good vids (I am looking forward to watching your next vid(s) about optimizing network communication). Also, if you don't mind would you be able to run some quick collision/physics vids? I am not sure if I have to tick the enable physics box for collision object, mesh object, or both... Also, do masses from collision and mesh combine for physics calculation? Thank you!!!

If you have, well, we all do anyway so just jump back in 😊 We have a lively Discord server so feel free to join us if you haven't already! discord.gg/GGeMXh7 I will be doing tuts on physics stuff eventually. If you want to simulate physics, it's usually the thing that's visible (like the mesh). It needs to have a physics asset for it to be able to simulate physics (the mannequin has it by default). I know it's not a super explanatory answer but I hope that kinda helps.

hey what should we do if we want to Show Respawning on both Server And Client side.Sould we just Replicate the function of Respawning?Does it work?

[@MetalHeadsGame]

Hey mate, I just want to say that your videos are absolutely amazing and honestly should be an official reference to learn from. So many videos (as you would know) have someone that has a terrible microphone or doesn't talk clearly, and they ramble or mumble for 30mins to get ONE point across, or they go on an overly complicated tangent that just makes the viewer yawn a million times and eventually wake up in a puddle of drool and a saw head from slamming into the desk at mach 10. You, despite having MINOR little tangents, make it entertaining, and those small tiny tangents are like little breaks to let the information sink in, plus those tangents are like 5 sec long, not 5mins long, not 5 mins. I'm guessing you have some teaching experience? Because this is textbook! :D While I worked on a personal battle royale project that was purely online and everything was procedural etc, I was actually really good with replication, and the project before that, purely online, same thing, and the project before that, so my knowledge SHOULD be good, but my current game, Metal Heads, has been mostly just Local multiplayer with the intention to do online later, and having been over 2 years since even touching online stuff, I for some reason seemed to have forgotten most of that online knowledge, which sucks. The last 2.5 weeks, I have been working on getting online play into my game, couch vs couch, drop in, drop out etc, and as I learn, I'm finding myself rapidly getting quicker and more efficient at the online integration. For example, yesterday, in a few hours, I converted a bunch of offline/local mini-games to have full online functionality, where as 2 weeks ago, I was dreading the thought, I figured they would take several days each. I only just saw this video this morning, as if the world was trying to tell me "You need this" and this video has helped clarify a few things for me, and taught me to rethink how I have replicated some things to try and smooth out the gameplay, since my mini-games have potentially hundreds of things on screen all at the same time pretty much all of which are moving, and all needing to be shown on server and client...and all relevant to gameplay, so it's difficult to try and optimize things, I simply cannot have the server updating positional data at all times. Plus I also need to factor in players dropping into a session at random, so they need to be updated with current information without lagging the entire server (of course if it is unavoidable, I do have the option to effectively pause gameplay while a client is joining, then unpause once they are updated, but that would really disrupt the flow). I have started delegating the aesthetics to the client now instead, and have the server just dealing with things like player deaths, triggers etc, but need to work on keep the client in sync with positional updates. For example I have a mini-game called Blue-Ballin', the level is on one giant rotating blue ball with 5 segments that rotate independently, and each segment has hazards, such as saw blades, and sweepers that rotate around these segments, knocking players off, plus the tops and bottoms of the ball have a hex grid, with each grid piece being a pillar that lights up, pulses for a bit, shakes to warn players, then launches outward to launch players flying...so yeah, lots happening, most of which the movement is handled in Timelines, there's timers too, and the server just cannot handle all of that at once, especially if it's a listen server. So I've now got the client dealing with a lot of it, but only aesthetically. And the server just makes sure that the client is in sync. This is the mini-game here: kzbin.info/www/bejne/bZ7ao6aXr76sq7s Anyway, thank you so much for this clear, concise and perfectly pieced together video, keep on doing it, you're doing amazing work and deserve all the positive attention. My only suggestions would be to add time-stamps in your description so we can easily just navigate to what specific things we need, if we need it. It just helps for reference later on if we come back to the video. I also posted on Twitter to help share your channel: twitter.com/MetalHeadsGame/status/1243340077641510918 Stay safe and stay healthy in this time, and keep up the amazing work :) If anybody IS interested in Metal Heads, the OFFLINE demo is available on Steam now, but I am working hard to get online functionality in place for you all. store.steampowered.com/app/1132670/Metal_Heads/

You win the record for the longest comment on the planet, hahaha! I know EXACTLY what you mean with the drool / saw-head. That's what caused me to create these videos because it took me way too long to just get the golden nuggets out of videos / documentation that I needed to implement in my projects. This video itself had 1400 different takes of audio.. I wish I could have lower standards and just hit record once and leave all of the um's and ah's in there, but I just can't lol Honestly reading the mindset change made me smile. That's my goal with these videos - to get to rethink the design and learn how to ask themselves questions while programming "where should this go?", "where should I be doing this", "does the server really care about this piece?" etc. I love it 🤩 I checked out your game, that is some FANTASTIC stuff you've got there! I absolutely love the Mario Party feel with the Metal - absolute GENIUS. Your winning screen transitions, cute hardcore characters, music, everything is extremely well done. You should be proud 😎 Also, thanks for the shout-out on Twitter man, I really appreciate it!

[@MetalHeadsGame]

YAY! I won a thing! :D No problems on the shout-out, there are many devs out there who are probably struggling to grasp some concepts, and when there are brilliantly made resources like this that are available, and sadly probably buried because of plethora of rubbish out there, I just wanted to give a little something back if I can. I would totally watch a blooper reel at the end if you had one too :D Thanks for the compliments. I absolutely cannot wait until I get online mode fully implemented, I'll actually be able to contact KZbinrs then, and get the game some more attention. Currently it's sitting at about 1268 wishlists, and 1300+ demo downloads, with demo downloads growing each day. It might sound like a lot, and it is, thanks to the awesome people supporting it, but it needs to be at least 10x that amount for the game to remotely succeed. I couldn't find you on Twitter at all. Have you got an account set up at all?

[@AndreXIII]

We will all be happy if you just release your videos :)

[@brynertoma]

Hahaha, me too.. I like the release part 😂

[@Technokarate]

I think it's worth noting that when you mentioned in 25:25 that the server also calls the OnRep function when the variable is changed only applies to blueprints. I seem to never get this behavior in C++ and have to tell the server to call the function manually.

[@brynertoma]

You are correct. I'll add it in the description / pin a comment just so people know. I've had a lot of C++ users run into this and bring it up on Discord.

[@elmanhamdi]

Hey Bry, please continue to part! 5 !!!!!!!!

[@matka5130]

EPIC

[@pegassus-oj1zj]

if i have an object duplicated in the map but i want each player to see a diffrent one of the object like in racing games how do i do that ?

[@justinpedersen9174]

Willing to donate body parts for part 5 at this point

[@FilipePintoArt]

Nice man! Really awesome content. The Length doesn't really matter. In fact, I think you went a bit too fast on this one a few times. I even had to put the video speed at 0.75 to make sure I listened to the words you were saying haha You can always try to split videos into 2 parts. I know they're pretty important to just split them apart, but you could simply split them and publish one or two days later. People that only find your videos in the future will see them in quick succession anyway and for us "regulars" you now have a reason to say you're publishing more often :p Also... that face at the start forced me to pause the video. I couldn't stop laughing x'D

[@brynertoma]

Good point. Yeah I caught myself a few times speed-talking. Beauty of KZbin is the speed change and the replay-ability lol I like your idea of splitting it and then just tell everyone I release content on the regular 😏 I just felt like this piece was a huge part of multiplayer and didn't want to lose peoples attention once they were invested. I'll perfect it eventually, just need a bit more practice / sample size of videos. That face killed me. The first time I set up the camera to rotate around him like that and hit play, I took a sip of my tea and instantly spat it all over the place as soon as it got to the face 😂😂😂

[@soap3010]

Where is part 5? 🤔🙁 Love your videos. Noone explains and show these things like u do. Longer and in deph is better than shorter.
