In this video we address the topic of multiplayer games made with unreal engine. Blueprints are an amazing tool for developing games especially for those who prefer the visual layout over written code. There are many amazing courses and tutorials to begin learning blueprints for free, however many of those that are made for multiplayer functions aren't developed with real world latency conditions in mind.

[@sundaysquire4013]

lol i did not expect GMC to be the first comment. Shout-out to GRIM, doing gods work with custom movement frameworks

[@MrSofazocker]

What does that exactly do? I read their store page, and it lists a bunch of stuff that is built into unreal engine as "Features", I get that its supposed to be a more general movement component, but why does it come with a "steam integration with UI backend"? like, even the confusion is confused here on what this thing is supposed to be.

[@sundaysquire4013]

@@MrSofazocker I've never even seen the steam UI feature of GMC? It's god tier for extending the character movement class though. Try and make a character with directional gravity and you'll see why this plugin is lauded so much

[@MrSofazocker]

​@@sundaysquire4013 It's at the bottom of the featurelist, they call it "Steam UI backend", how a UI can be backend idk, if he means they made bindings you can call from UI, then that's pretty weird, as the Steam integration already gives you those!? But you can extent anything from the character movement component using your own components, or even make child class of it and expose the things you want? Like to donwards vector? I still don't get it, sry. Like I do not doubt it will speed up the setup of characters, animations etc, it seems to support a wide-range of them. But depending on how you want to trigger those and how they affect gameplay, you will end-up making your own system either way. Nothing can fit your game perfectly, or elese you'll end u making your game conform to the tools you used. But the notion that this is somehow not at all possible using plain Unreal Engine is myth.

[@Studio1-7]

Thank you for doign this video! I hope everyone learning Unreal stubble across this. For I was in the same situation that you were in and had to go through all of the headache that you did.

[@yahootube90]

From personal experience, I can tell you that Unreal's movement component is very, very rigidly coded in certain ways. This is just as big of an issue in C++ as blueprints. As an example, I was doing a project with spherical worlds. Unreal's movement component however is hard-coded with gravity going in a specific direction, up being a specific axis, etc. So custom rotation? Yeah... no. You basically have to rewrite entire sections of the component to get it to do things like that. And that movement component is freaking massive. Latency may be a bigger issue in BP, but the movement component is thousands of lines of rigidly structured code.

[@Gorgonzeye]

I'd say its not that hard to fix the gravity yourself in a child class, but they seem to have changed it so the get gravity function is no longer public. Hooray for maintaining a custom engine branch.

[@MrSofazocker]

That pretty much a non-problem. You also dont have to recode everything, the movement component isnt a component by mistake. Components enable you to compose (duh) functionality. Instead of being stuck with the functionality, you can simply extend the character component with your own stuff, by utilizing all the replications already setup from the character movement component, as it is server authored, you can let the server handle everything, The players only get their updated position from the server, they dont move themselves. This is also to prevent cheating. For things like speed hacks, etc. Imagine you could tell the server what ever you want, and the server updates your position for all other players, simply bcs you said so... That's not how you do multiplayer games. (Tell that Bethesda... yeah Fallout76 movement speed was tied to your fps, and was not server authored, so you could sprint at mach2, not fun)

[@jacobsoares7068]

​@@Gorgonzeyeyou could just copy-paste the source code of UCharacterMovementComponent into a new class and modify the parts you need.

[@Gorgonzeye]

@@jacobsoares7068 That method would cascade into having to replace ACharacter, and then recreate everything that normally references AQCharacter.

[@BoryDev]

I hate it too! I totally understand where you are coming from. That's why I tried to suggest Smooth Sync plugin depending on your type of game (seriously if big game with online cheaters may not be an issue for you, then smooth sync is a decent option). In the original recording of this video, I had a section towards the end saying that I really don't like that the only solution I can provide to people is to spend more money, but at the end of the day that's what we need to accept when it comes to these topics I think. Either we gain the years of experience ourselves (which I think is astronomically helpful in the long run) or we can pay for the work of others, which is what we have decided is best for this project given its timeline.

sick video, what multiplayer series do you recommend for unreal? trying to find one that does things through steam using blueprints and it's a bit of a struggle lol

[@capnc4ke]

I'm currently facing this same issue in my game. I've gotten as far as I have by coding it all in the character, but even in "low" ping cases the player will rubber band. Especially if they spam the sprint key, like you showed. I've had my eyes on the GMC for ages, and it's good to hear from another dev that it's worth it. Once I can scrap together enough money to get it, I will definitely be buying it, as I think it'll truly make my game WAYYYY smoother for clients. Though I am still worried if it can replicate some stuff that's specific to my game. Either way, I appreciate the insight! Spanky looks really interesting, you've got my sub, and as a fellow multiplayer dev, I can't wait to see further progress!!

[@BoryDev]

I really appreciate it! Your game looks like an incredible amount of work, I'll definitely be keeping up! The GMC has definitely saved our project as more then half our movement is custom (and was broken with latency) but it does have it's learning curve.

@@BoryDev Talkin about GMC and Smoothsync. Non Competitive Multiplayer game comparable to FiveM Lobbies : Smoothsync or GMC ? Which is easier to setup in the long run? I may have to redo everything, but i just want to start with the basic movement there is in UE5 and then redo it later on when i got enough experience.

[@BoryDev]

​@@DarkSession6208 If you aren't worried about cheaters *at all* then smoothsync will work. But I will say, using smoothsync is basically heaven for cheaters, it is pretty much entirely syncing data from your PC, which means a cheater can manipulate data as they please. You can also use smoothsync in conjunction with the regular movement component as it is not really adding movement, but syncing location & rotation from your local PC to the server (and everyone else) so its useful for physics objects too if you need. I wouldn't just throw it on everything though, performance is still necessary. GMC is great if you are ok with rebuilding all movement and finding solutions to movement problems yourself (most people will help in discord but its still all you) and it is also much more authoritative in the sense that the server will correct you if there are location or data differences. So it will protect you more than smoothsync. If you are still early stages of figuring it all out, I would recommend staying with the default movement and smoothsync if you run into issues. When you have more experience or know *exactly* what you need to make, you will understand if you need the GMC or not - until then smoothsync would be ok.

[@DarkSession6208]

@@BoryDev i know your game was very specific, but i thought some months about this whole problem and still did not come to a conclusion. Do you think it would be a good approach to use a C++ Approach for Sprinting and slap Smoothsync on everything else ? (Vaulting for example) ? My goal would be to rule out velocity changes and teleport, so speedhack and tp. Im just not sure what Cheaters can use to hook on, i mean from what i know the walking state, jumping state is well replicated and not the problem, its just the custom movement different from the CMC that is causing hackers to hook onto this right? So if i would use C++ for those 2-3 custom states i have and keep everything else default or use smoothsync for non critical stuff? Im asking because 1) i looked into GMC and hell people say it took them as long as if they would learn C++ and with V2 they raised the price to 700€ .

[@rifat.ahammed]

Thank You

[@RDD87z]

very very useful,. I v got 2 questions :) plsss. How much did you take to learn all the programing part to get to this game? (with ur animation and 3dmodeling base)? and a curious question,. if its 200 ping, why did at 9:50 ur left player takes 500 miliseconds (30 frames at 60fps) to actually hit the player on the right screen

[@BoryDev]

Took me a decent 6-8 months to really feel comfortable with the programming. I was up and running about 2-3 months in, but to really understand the flow of everything without needing tutorials and such took some time. I think it's important to highlight that, even though I was (and still am) deep in developing our game, I am always learning and getting better. Second, the ping is a little bit misleading on games that are peer-to-peer. And there is no way around it, the simple fact is when you are peer-to-peer the actual network ping is pretty much double. Because there is the time to the server player, the processing time, then the time back to the client player. It's not exact but as a general concept the ping takes roughly double the time to process on peer-to-peer. Glossing over that fact, we display the ping of just your machine in our game. We could "fake" it and double it to give a better representation, but at the end of the day as long as it gives a general idea of your connection then that's what's most important. It would also be a little misleading for people to see themselves on 140 ping when connecting to close friends, they might think something is wrong when really its just the peer-to-peer ping.

[@zerohcrows]

Holy fuck what a perfect time to find this video, ty so much

[@hieptranngoc2584]

thanks

[@timothyedrickburhan]

Regarding GMC, What about other actions? (except movement) such as: punching, kicking, shielding. is the prediction & rollback still applies?

[@BoryDev]

I'll try to answer my best however I don't want to confirm anything as I'm not the developer. From what I can understand the GMC is meant to handle everything that 'moves' the player as it is essentially made to replace the movement component only. However It's up to you if you want to handle a punch or kick anim through the GMC, we do our slap animation through it (doesn't need to be) but you need to make sure any logic that happens as a result needs to be handled accordingly. Our slap is on overlap outside the GMC. Other people have asked about knockback etc which needs to be handled outside the GMC too but then 'tied' into it properly since knockback is a form of movement. So it's a very situational answer, it will handle prediction of any variables you bind inside it but you need to be smart about that. I think if you want fast rapid kicks and punches, it could be good to handle the replication and prediction of those inputs and drive the animations, then any resulting gameplay logic done outside. Don't put things like health, stamina, or shield etc meters inside it.

[@chickenslips]

It's unreal to me (pun intended) that this is such a MAJOR flaw in the engine, and nobody talks about this. If you want your game to have any kind of uniqueness/sauce at all, it's gotta have its own movement system. I feel like Epic is putting all of their resources into impressive graphics, and forgetting about all the actual GAME pieces. I see so many show off videos of rendering things in UE5, but almost nobody has a handle on how the CMC works, and how to extend it. In general, the design of the CMC is abysmal, and I can't believe Epic hasn't provided a better solution or at the very least more insight on how to make something that goes beyond the standard movement modes and simple "go to position" type movement. The GMC from what I can tell is superior in every way, but it's so expensive. I don't understand how Epic hasn't bought it out and adopted it. I personally can't spend that kind of cash on an asset right now, but it seems incredible.

[@nodesofnature603]

The character movement can be client predicted and server authoritative with GMC but what about other actions such as weapon simulation, is there any solution for that?

[@MrSofazocker]

Have everything server authored, you dont need any plugins for that to do so. Weapons are similar, let the server simulate everything, only send the results to the player. Idk why the creator of the video makes such a great fuzz about it. If you programm the thing like you should (using the tools epic gives you) you wont have any problem. Not with custom movement, custom items, physics replication, everything works flawlessly, if yuo do it like epic wants you to do things, aka the easy way = Server authoritative. You can of course execute everything the same way client-side optimistically, and update from the servers result, so things happen immediately, but end up using the servers result.

[@charlay23]

Seems you got thrown in the deep-end, and it's a success story! Really great video, happy to watch. Thanks for sharing! Inspiring and hopeful 🥺

[@DarkSession6208]

I also find it amusing that the whole unreal community sees this as the hugest problem that they use Client Authoritive Data Streaming when basically GTA V, DayZ in its early stage, EFT etc... all had absolutely ZERO anticheat and everything was client side, and now they added at least anticheat and people are still cheating because you just can't prevent Aimbots and Wallhacks. I don't see any reason to focus so much on anticheat when everyone will cheat anyways. CSGO would not need to have VAC at all because everyone who wanted to cheat could cheat without problems in the past. So where to draw the line...

[@aycaramba1773]

200ms is ok for fun game, but if u want competitive multiplayer, for exemple like valorant, CS:Go, Call Of Duty, it's too much delay :/ we can't grab C++ code and add to our project like plugins ? and then have same performance than people who use C++ ?

Does this framework work on console? or will this limit a game to PC only?

[@paxphillips3125]

About six months late here, I fear, but... While the framework only ships with Windows binaries (and an AllowedPlatformList of only Win64), I can attest that it works fine on macOS and Linux as well; the Windows limitation in the .uplugin and on the store page isn't because the code is Windows-specific, it's because Grim can only build and test it for Windows. Given that it *does* work fine on macOS and Linux once you strip the AllowedPlatformList out (and build the plugin yourself), I would assume it would also work fine on consoles.

[@BoryDev]

I don't think any game is safe from huge headaches in regards to replication unless you have enough experience to say that for certainty yourself. Best I can say is to prototype as much as you can and at each stage always remember: launch 2 separate instances/windows in standalone with one as a host (or host in background) and play with "NetEmulation.PktLag 500" where 500 can be any number you want to test in milliseconds of network delay. I did not know to do that myself, and that's when I ran into the realization when testing with friends that my movement is more complicated than I thought. So always test with emulating pktlag and just look for anything you wouldn't want to see in a real game

[@BoryDev]

We don't use any vehicles but I know its possible and there are others in the discord developing vehicles and ships with it. Depending on how realistic you want the physics interaction will dictate the amount of work. It's not a plug n play solution especially if you want to build a physically simulated vehicle (looking at the discord this seems possible but is some uncharted territory), but for arcade feeling cars I think it would be similar setup to characters. Overall it seems like physics is the biggest hoop for vehicles, I would imagine the replication and prediction part would be just as stable as anything else in the GMC

[@JOSE-rl7dd]

Eos integration system helpful for this custom movement? Can anyone explain

[@BoryDev]

EOS or any other online subsystem don't really have much to do with the moving or replication. They handle the sessions, lobbies, friends etc. and other online systems. But the replication of data is the same with all - so using different ones shouldn't affect movement or gameplay at all.

Sorry for my ignorance. I'm still just looking into game engines. Can someone explain the following. In the GMC plugin page, it say it only supports windows platform. What does that mean? does it mean that any code I make cannot be then exported to game consoles in the future? sorry, noob here trying to develop my own game.

[@BoryDev]

Many plugins will say the same thing, it just means that the developer is only making it to work for windows but for a lot of plugins you can still export for other platforms, sometimes you may have to recompile the plugin yourself. Essentially the plugin developers don't guarantee anything will work on anything other than what they support, but that doesn't mean it's impossible for you to do yourself :)

@@BoryDev Thanks, and really cool game you are making, I really enjoy the videos! Just to clarify what you are saying. This 'limitation' would limit me on the dev side, or you are saying it could limit the final product side (eg it won't compile on PS5). Because a quick look though plugins, I don't see a single plugging that shows PlayStation support per see. It seems to me its more for the dev purposes. On a different topic. Can you make a video of the plugins you have used/ recommend? Thanks again!

@@user-zy6wg5qt5f I'm not sure if this is what you mean, plugins shouldn't affect you as the dev working on your project unless perhaps the plugin doesn't natively support Mac and you are working on a Mac. In that case it would affect you because you would need to rebuild it. But otherwise, if you worked on a PS5 project, it wouldn't affect you until you need to actually build and test the project on a PS5 The way I understand it is that Plugin Developers will only list what platforms are supported based on what they are able to test with. If a plugin developer doesn't have a Mac, they would not put Mac on the list of supported platforms. Same goes for PS5 or Xbox, if the plugin developer can't test their plugin specifically on those platforms then they would not say it can - BUT in a lot of cases the plugins will work perfectly fine (might still need a quick recompile to allow that platform) because the code that the plugins provide are just C++ that the engine exports to those platforms normally anyway. However if the plugin uses an external library / dependency (idk what the correct language is) that is not native to the consoles or unreal and is some custom library of data that's when it gets tricky.. I think .. don't quote me on that because I am not 10000% sure but that's my understanding

[@paxphillips3125]

To add to this thread, I can personally attest that GMCv2 builds fine on Linux and macOS. The plugin is set up for only Windows (because that's what Grim can build and test on), and only provides Windows binaries, but the dev does make an effort to ensure that everything still works pretty much out-of-box on macOS and Linux if you strip the "AllowedPlatformList" out of the plugin file and are prepared to build it from source yourself. In testing on Linux and macOS for Grim, I've also tested on Android and iOS and can confirm that (not shockingly) it also works there. As such, I figure the chances it would compile fine for consoles as well are fairly good.

Most unreal tutorials are like this, they lead you down the wrong path just to get something quick to put in a video. Then you go to make a real game with those techniques and it falls apart. Epic themselves are the worst for this, they do those short tutorial streams where there's no way they could cover the topic in enough detail to be real. It's a big trap indeed.

[@aadityarajkarki7610]

does this plugin support android build?

[@BoryDev]

It's only officially supported for windows at the moment

[@Madd_Jack]

As an engine used in one of the biggest multiplayer games (fortnite), I feel like they should have this NAILED DOWN somewhere other than custom addons.

[@larrynachos]

Kinda bummed that the answer was a 350$ plugin... very informative though.

[@xjuliussx]

it was 350$ when you checked? 10 months later is 682$!

[@misc.2331]

Does GMC prevent the client-authoritative cheating problem or cheating in-general?

[@BoryDev]

No not really, although technically server authoritative approaches like the GMC are better, if people want to cheat they still can.

[@misc.2331]

@@BoryDev Ah damn. Still sounds like a good plugin though. Even with this plugin would you still say that blueprints are not well-suited for creating professional-level multiplayer games?

[@joel6376]

So.. if one was making a PVE add on for an existing game (that is multiplayer and works okish) and wanted to ensure I don't have to recreate everything if I decided to do multiplayer - would it be advisable to use this from the get go. The cost is not prohibitive at all (for me) and on the off chance I decided to go that route (or if I reuse what I create in another project in future) would you recommend just starting with this plugin instead?

[@BoryDev]

Is the existing game made by you or is the PVE add on kind of like a user mod? I guess this is a bit of a larger design choice, if I thought that there's a chance that movement in your pve add-on could become a limiting factor then I would personally just start with the GMC. In my current project I spent longer than needed making my movement only to redo it all with the GMC. And unless I learned more about the unreal movement component and C++ I don't really see myself needing to go back at all for this project.

[@joel6376]

@@BoryDev We have been playing/polishing (to our ability, I have videos uploaded) multi for a few years and tinkering with the idea of doing something that involves single player. I guess my ultimate concern would be doing this, being mildly successful and people asking for coop. So if this is some middle ground for doing that.. it might be useful. To clarify this is more for the enemies and not the players.

[@BoryDev]

I think I understand a bit more now (your movement looks very nice btw). The GMC is good for singleplayer too and code-wise is pretty much exact same workflow as multiplayer GMC. So if you made singleplayer with GMC then want to convert that to coop - you shouldn't have much issue at all swapping from single to coop as the only major difference is just making sure the variables are replicated properly, that's it. However if this is just for your enemies (supposed they're AI), I can't really vouch for AI yet because that is our next months task we have yet to undertake and I don't see a lot of people posting AI showcases / W.I.Ps in the discord. I know some people are doing it, I just don't see it posted much.

It's weird hearing an Australian say "a couple friends" without the "of" in there.

[@unrealstudent2239]

i dont get why epic games dont just buy gmc and include it in the engine, or make something better (if thats possible). its difficult to understand how they can focus on metahumans and all that stuff but networking which is arguably one of the most important parts of games is so weak without a plugin like GMC. is it that they dont want multiplayer competition for fortnite from indies?

5.4 has the solution, also ability to change collision shape at runtime.
