Synchronizing Data between Clients/Server | Unity Multiplayer Tutorial

[@arin_faraj]

You basically started the best networking course for unity keep it up

[@nickjasperr]

i couldnt agree more

[@publicalias8172]

Love how the essentials are just, explained. Like why is every tutorial so spaced out and under-explained ? "just type this and this very specific function will work" this is a gem!!

[@tehuster]

Liked, Subbed, Belled all the hola's. You got a great talent for explaining things. Please continue making great content like this!

[@openpineapple2205]

I've been trying to wrap my head around this stuff for weeks and it turns out all I needed was this one 30 minute video. Thank you.

[@brokenMikrophone]

These Tutorials are incredible. I love how well structured and organized they are with the labeled sections. Keep it up!

[@mauricioolavarria6479]

Thanks so much, i was so lost in the mirror implementation, im a huge fan of your content, if i wasnt broke as and with a child i woul pay you for this. im sick of good tutorials giving limited information and asking for payment, im looking foward to make some money with my game, and i promise you will be in the credits for that :D

[@ShrineApp]

no worries man I hope you build something great!

[@zyntist]

These are the best multiplayer tutorials, period. Thank you again. Just a little clarification on the [SyncVar] example, in case someone was confused like me. As the holaCount property is initialized in the player instances, there will be one holaCount property for each client, althought they have the same variable name. So if client 1, sends 10 holas, its holaCount will update and be sent to client 2, but client 2 will still have 0 holas. If you add this to the OnHolaCountChanged() you will know of which client is the shown holaCount: Debug.Log($"Player with NetID {netId} had sent {oldCount} holas, but now he has sent {newCount} holas.");

[@hoody4289]

Thank you ! I was wondering why I wasn't getting the same amount on each...

[@robertholl8914]

3 days trying to figure out how to send Commands without authority... wish I'd of gone through this series a bit earlier. Great tutorials a lot of information and looking forward to more. The information here is the most relevant I've seen on the subject and very informative

[@Ayyouboss]

Simple Incredible and definitely way to underrated! I've subbed from the bottom of my heart. You have made my day!

[@alexanderpaul5775]

Great video, keep on the awesome work!

[@fillament]

i spend the whole weekend trying to make commands work. Now it works.

[@iksuddle]

WHO WOULD DISLIKE THIS SERIES IS GOING TO BE AWESOMEE

[@NoelTugy]

I'll definitely watch this tutorial again when I'll try things around! Thanks man! :)

[@nickjasperr]

every other tutorial ive seen up till now has been just showing me what to do, but i dont care about all that, i wanna understand how everything works, how to use mirror on my own, this and the last are the first acctually useful tutorials, thank you, you helped me sooo much dude u have no idea

[@grey3623]

I don't write comments often but this one deserved it. Easily the most useful tutorial I've seen on Mirror, even compared to their own documentation! Quickly, cleanly and without confusion you explained all the things I needed to feel confident about what I'm working with. Earned a sub! :)

[@tauheedgamedev2388]

Real in-depth guide on Mirror. I was thinking about adding network support to one of my games but couldn't get to grips with it. After watching this video Im gonna give it another go and if it works I might even add network support to my current Game project. Thanks. 👍 Subbed

[@nikilkumar1000]

Who the hell are those disliking these videos? Something is surely wrong with them. These videos are so well made and concise.

[@eduardorabanal2803]

great tutorial, I've already enabled the notifications, thanks a lot

[@ゆかなえ]

Amazing! Best networking course! I have started writing unity for a month, and 2weeks with mirror. I have almost finished the single mode UI, but when I imported mirror, I MESSED UP so hard.... After watching this video, I start understanding the data Synchronization logic, THANKS!

[@gamedevtitan5040]

The only mistake i could find in this video is that at 24:42 there is a ' ] ' missing after ClientRPC other than that the video is perfect.

[@Sagaan42]

These tutorials are the best multiplayer not only tutorials but even just explanations I've EVER SEEN. You're amazing.

[@yiguanliu2318]

Learned so much from your tutorial as someone who has zero knowledge on how multiplayer works! Thank you ! Very clear content

[@Tr0janH0rs3]

Thank you so much for this amazing tutorial! I was stuck because I didn't know how to use properly mirror but this tutorial helped me SO much.

[@anselmx3]

Liked and subscribed, it's amazing how you describe everything clearly and quickly. The visuals really help too, keep it up!

[@yuribento]

Thank you so much! as a web developer i was searching for something like this for a while... i have to say: this is the best unity multiplayer tutorial that i ever seen. Subscribed!

[@Kromahtique]

Your explanations couldn't be more clear. Thank you so much for you work.

[@cainen6355]

This is a brilliant series! Very well structured and explained! Great work.

[@siRrk1337]

this is the best of all the tutorials on mirror i could find! by far. i think i can do with what you taught us, but i would be watching and linking additional entries to the series :) for example, id like some common mechanics implemented, like players shooting at npcs and each other. basicly principles on where and how to use commands and rpc!

[@nilla_studios]

Man you are awesome! I am creating a multiplayer game and was just doing stuff without knowing how exactly it works. But now I am working like a boss 😂. I have subscribed + turned on bell notification for not missing any video you upload. Hopefully I can complete what I have started 😀

[@Exori]

Amazing for someone with dev experience who wants a kickstart into multiplayer dev in Unity, please continue, I love the videos.

[@fernanlaracapito5961]

Thank you, the best mirror networking tutorial !

[@TheDaKSn]

Really well made. Subbed! Keep it up!

[@HelPfeffer]

I love this serie. Thank you, this helps me A LOT.

[@RugbugRedfern]

Thank you so much! This is amazing, and exactly what I needed. A sub for you!

[@drummsnikk5073]

Keep this up man, it's really incredible!

[@NETRUNNER_03]

I cant describe how amazing this is. Thank you Thank you Thank you!

[@glenzhang3646]

Super great video, looking forward to more

[@alexleonardkrea]

I wish I could like this more than once! All of these tutorials are top notch! I'm now subscribed for anything you feel up to releasing in the future. Thank you for putting the time in on this!

[@noscopeowl4653]

You are amazing, really blew my mind how a 30 min video could teach me so much

[@harrydavies6531]

Really good series and very useful. You’ve got potential man and I can see you becoming a big game dev youtuber one day

[@suryanshkulshreshtha4095]

I love how you give time for part its a time saver

[@antoniodiaz4603]

great stuff. Can't wait for serialization, it seems very useful

[@philipp3250]

That's hands down the best Unity Mirror tutorial series out there. Hope you'll get more attention in the future so that you stay motivated to provide more of these brilliant videos for us.

[@amadhia]

FANTASTIC tutorial in every regard! Thank you so much for creating such a top-notch tutorial! I’m looking forward to watching the rest in your series!

[@Future_Guy]

Learning a lot about Mirror from these. My only wish is that the example you give for the various tagged methods, they happen across multiple clients and not just one client and server. For example, regarding the TargetRPC tag, I want to see the behaviour of a different client when pressing the X key.

[@mrhandy1784]

Love the tutorials! Super helpful and educational. I am trying to build my first multiplayer game and these videos are a lifesaver. Cant wait for the next one! :)

[@richardstevenson371]

This video... is amazing. Feels like I'm getting a proper lecture that I would pay for. Subscribed for sure! : )

[@matthewwoodc0]

Wow. All I can say. This is a fantastic tutorial, could be the best one out there!

[@thesporehero]

Thanks, great tutorial! This helped me past a bit of a networking brick wall in something I was working on

[@CarlosHernandez-gv8sn]

One of the best, simplest, and easiest to understand Mirror networking tutorial out there. Having said that, I am having difficulty with Instantiation. Could you do a video on instantiating object and they’re specific Authority / updating all clients?

[@kankurokano3926]

The tutorials that you make are the only tutorials on youtube that teach just the basics of Mirror in a really simple and understandable way Great Job If possible could you make a tutorial on making rooms and matchmaking?

[@Whaiitran3106]

impressive class! you made a such complex thing like this looks like so simple! thanks!

[@RogueWorlds]

awww yeah, give me that multiplayer juice!

[@icebrn]

I love these multiplayer videos. Keep up with the good work

[@andrey3061]

You explain to me that I try to understand for a week, thanks!!!!!

[@midniteoilsoftware]

Another excellent video. I’m looking forward to the next one.

[@asfand6904]

Great series bud, keep em coming!

[@randyh3761]

Great content! Love your examples and explanations

[@techmaster90]

This is very well made and you explain things clearly.

[@Crocofrozen]

Very good explanation, great youtube channel !! I can't wait to see the next videos !!

[@tatomarinelli7937]

Amazing tutorials! Greetings from Argentina 🇦🇷

[@brucescott7156]

I need more of this, it's so good

[@edwardkarra6027]

you are just... GREAT! Thanks!

[@stevengibson4773]

Having trouble as the docs don't seem to specify the answer to this. The tutorial looks a tad out of date. This callback no longer seems to exist public override void OnClientConnect(NetworkConnection conn) it looks like it throws an error for not existing. I looked at the docs and there looks like a virtual method, but it doesn't seem to behave the same way. Any ideas how to move forward?

[@caindallm9746]

hey, i got the same issue, have you found any solutions mate ?

[@oriongames1211]

That wont work because its NetworkClient.connection is a static class. OnClientConnect doesnt take any parameters. I was able to get this to work by doing the following. public override void OnClientConnect() { base.OnClientConnect(); Debug.Log("Connected to Server!"); } public override void OnClientDisconnect() { base.OnClientDisconnect(); Debug.Log("Disconnected from Server!"); }

[@BudPuen]

@@oriongames1211 You save my day mate.

[@ahmedthegreat3973]

25:13 You Forgot A Close Bracket "]" After ClientRpc. BTW I LOVE THESE VIDEOS. VERY DETAILED. Subscribed

[@piztech5168]

29:31 The holaCount value doesn't stack together in the server when you press X on different clients. When I press X in 1st client, it starts adding 1 until I reach 10 for example, but when I press X in 2nd client then holaCount value starts from 1 or goes back to 1, the holaCount should be 11 to all clients by that time. Isn't SyncVar supposed to update the variable's value to all clients and the clients can add by 1 each time they press X and continue to keep stacking in the server? Idk why this happens and it's not making any sense

[@danielemessina1979]

having the same issue here, did you find the explanation? EDIT: I get it now, the sync var is shared and sync'ed among the instances of the same object across server and clients, but two objects, like the two players, will each have its own, it's not like a static class variable. So what we see is holaCount for player 1 and holaCount for player 2.

[@piztech5168]

​@@danielemessina1979 I forgot to edit this comment, I moved to MLAPI networking. And before that, I just thought it had the same system as Roblox Networking where u sync 1 variable and it would automatically sync to all. In MLAPI, I solved this by doing an "if this is server then variable is incremented" condition after you send the signal from client to server. MLAPI is not much different from Mirror so give it a try.

[@mickmickymick6927]

A tutorial I can actually understand. I only see one more video, I really hope you didn't stop this prematurely cause it's much easier to follow than Tom Weiland's one and goes further than Dapper Dino's one.

[@nootherkyle]

Admit it its the most explained networking tutorial..

[@xGAMER-xc4tm]

im an absolute beginner but u rly gived me a lot of informations :DDD

[@mahdiruzmeh7862]

thank was very helpful. keep continue

[@Celcious]

just love this channel.

[@JimboS1ice999]

please continue this series!

[@nefuzo627]

Nice video, helped a lot :D

[@chatbear69]

Love your videos and how you explain the details and the implementation of the code. When you get a chance could you make a short video on how to create a custom GUI for the multiplayer. That would give me, and maybe others, the next step in completing a game. Thanks for your time and expert advise on getting things up and running.

[@xGAMER-xc4tm]

thx dude yu rly helped me a lot :)))

[@theholycity7498]

This video is very informative and well- explained, very helpful! Will you be making more tutorials on Mirror in the future still? I noticed it has been a while since you posted any.

[@NLPIsrael]

not sure if you are the adress for my question but i wonder how can i call simple events from one sciprt to another - if i want ti add listeners and invoke a message i discover the listenr is not getting the event. i usepublic static class EventsManagerand i put there all the relveant actions and it worked - untill netocde...

[@gabrieldj8191]

I have a problem with synchronizing the player itself. I am using the karlson movement script (rigidbody) and every time a client joins a Host (Client + Server) It blacks out the clients view and causes the Host To be in control of the other rigidbody character. This is weird, I also have Network Rigidbody and Network Transform

[@somedevstuff5060]

Awesome tutorial

[@harunakdogan41]

Nice tutorial!

[@potatolegacy]

ur a life saver man thx

[@12457p]

I want to say thank you Senpai

[@keepinitreal551]

For some reason OnClientConnect and OnDlientDisconnect does not appear as an option for me. Has this changed?

[@oneeypi]

Check if you inherited from NetworkBehaviour instead of NetworkManager

[@noobsaibot7688]

in commands section when i press x only the host receives the msg from the method Hola() + when i press x in the second unity editor the msg exectutes in the host .. need help please .

[@Zihenroy]

So syncvar alone is not enough to sync player hp? Since player hp is on client not server? Cuz mines are synced without hook. What did i misunderstan?

[@Hazuuur]

Hello, I facing issue with synchronization in my project. I have interaction system where player must look at target and then press 'E', so it works fine when host tries to do that. But if you are a client it works only when host loot at target, client press 'E' and event happens on host's target, not client. I tried to use [Command] [Client] [Server] in different places but problem is always the same. Maybe someone has any clue where I made mistake.

[@moe9647]

amazing work

[@techmaster90]

Can I sync "Collision2D x" using a command and then a SynVar with a Hook and then a ClientOnly Method? I get an error. I don't think I can pass in the new Collision2D value in the the client method. How can I do this?

[@vader777]

So would you say that sync vars would be the best to keep track of the transforms/actions of AI agents in a game?

[@petsiskonstantinos1347]

@Shrine what if i want to call a [Command] from an object that is not a Player???

[@arandomrcreature]

idk if its in this video, but how would I call a function from a spawned prefab?

[@shivamchauhan2673]

You are amazing!!

[@jayantbarthwal4470]

how to syncVar from client to server .(if i want to send my player input to server to perform some movement )??

[@BluePhantomStudio]

Ok So I understood what u said but I m confused that which rpc to use to show projectiles and flash to other clients

[@blue_lobster_]

Wow that's awesome

[@_zero9343]

So say I instantiate a game object with its own Network identity using the host's scene. The client then joins the game, but the game object (fallen tree) is not instantiated because it does not exist for the client. The initial code for the instantiation was on the tree controller which is now destroyed. Is there a solution to this issue? My only thoughts were the following: leave the tree controller running, and allow the fallen tree to remain a child of the gameobject... or perhaps store a list of all the possible fallen trees on a serverside controller, which then instantiates all fallen trees when the player joins. Has anyone else run into a situation like this? Any suggestions?

How to communicate between client1 to client 2

[@MrQQtis]

Lets just say I want to register players for event. I need 5 players from whole server. They are on different scenes. Can't see each other. They click button to register and plays there own game till event start. Is there any way to notify registered players without sending message to all players on server?
