If you're having trouble adding the packages by git url, simple add these lines to your Packages/manifest.json file at the root of your project: "com.veriorpies.parrelsync": "github.com/VeriorPies/ParrelSync.git?path=/ParrelSync", "com.unity.multiplayer.samples.coop": "github.com/Unity-Technologies/com.unity.multiplayer.samples.coop?path=%2FPackages%2Fcom.unity.multiplayer.samples.coop#main", "com.unity.netcode.gameobjects": "1.0.0-pre.9",

@hollowsoul5499 2 года назад

Hello i installed the packages by adding those lines in the manifest but after installing it now says that the script har errors of missing semicolons and invalid expressions term '[' they are all invalid errors since that I checked the place where he said expected semicolon it has it there so do I need to do something to make it work well ?

@hollowsoul5499 2 года назад

I found my problem ... for fututre reference to people this doesn't work on older versions of unity I was on 2019.4.11f1 and it gave me an error then updated to 2020.3.32f1 and it worked well

Told my wife at dinner that i wanted to possibly incorporate some bit of online multiplayer in my next project but wasn't sure it'd be feasible to add so much networking code to add the system and an hour later this video drops on my notifications 🤯🤣

@SpicyMelonYT 2 года назад

This is exactly how I feel with a game I am making. I told my friend that we just couldn’t do multiplayer yet cause it would be too much for me with my current understanding and then this banger drops

@stephenc281 2 года назад

This video is the best networking video I've seen so far. Thank you so much for making it! I've been trying to figure out multiplayer in Unity off and on for almost a year, and this video explains things so much better than all the other ones I've tried to follow in the past. But of course, it's only half the solution because, to make a real multiplayer game, you need to implement relay/NAT punchthrough so other people can actually connect and play with each other, and I'm SO glad you're going to do a video on that part as well. I can't wait for it! I feel like with these two videos, I'll finally be able to dive deeper into multiplayer games.

@168LAN 6 месяцев назад

if you are having trouble adding the packages from git, try add them manually 1. open the git link. 2. open " code" tab, its underneath the folder name on the left side of ur screen 3. press the green "code" button, you should be able to download it as zip. 4. extract the file 5. open unity package manager, then add from disk. the file you need to add is package(.)json, for multiplayer samples its in "Packages/...unity.multiplayer.../package(.)json "

@grommy9179 7 месяцев назад

Oh my god, thanks so much for this. I have spent the last 2-3 weeks trying to figure out how to properly sync shooting in my school project. Since I didnt understand Client prediction I was just trying anything to make it work even if it meant it would be easy to cheat in but my knowledge of the netcode isnt great since this is my first project in it so i just stumbled and every idea would just create new errors. Every video i found on this is just people using ServerRpc and then show it off locally so theres no lag, completely useless. However you showed it off with the delay how it would actually look after implementing a true multiplayer into the project and then showed how to easily fix it. Really awesome, youre the only guy that actually showed the problem with using ServerRpc and an easy fix. Just wanted to say how grateful I am since I needed to resolve this sync problem in 2 more days and I was about to spend the whole day probably making no progress just digging through someone elses code trying to figure out how to make it work.

@michaelwilson8461 2 года назад

Nice example. I like when people show straight forward examples without a lot of bloat. It keeps it simple to grasp the basic mechanics, from there it's easier to build out functionality as needed. Rather than wrestle with a bunch of nuance to determine what is and is not necessary.

@VyvyanTheGreat Год назад

VERY IMPORTANT: If you're using Netcode 1.0.1 Or higher, adding the "Destroy(this)" in the OnNetworkSpawn throws an error and breaks everything. Alternatively, you can put an ` if(!isOwner) return; ` at the start of your update function instead.

@huryelcb2746 Год назад

Yeah, unfortunately :/

@jenssundqvist17 Год назад

Running through an Update() for every player feels iffy. I changed the if (!IsOwner) Destroy(this) to: if (!IsOwner) this.enabled = false; and it works like a charm

@DanielPham831 2 года назад

21:45 I think you should also need to send the shootPosition + shootDir because at the time the other clients run the ExcuteShoot(Vector3 dir), that player could possibly be at another position which leads to the balls go at different pos too. But anyway, thanks for the tutorial. I have learned a lot since I pressed that subscribe button 😁

RigidBody physics across a network is a pretty advanced topic, where you would have to implement client side prediction and server reconciliation. It was definitely oversimplified here.

For people getting an error after adding the code at 6:40 - when you add your player to the player prefab in the network manager, also add it as a network prefab. This fixes the sync issue without adding this line of code to the player controller.

Primero que nada, TE AMO (tu comentario me ahorro mucho trabajo), segundo en mi caso esto me dejaba otro problema el cual era que en mi pantalla se movían los dos personajes (tanto el base como el del clon), y lo que hice para solucionar eso fue crear un if en start que marcara un a una variable como True si el personaje era controlado por el usuario y dejara como false si era de otro jugador, y en Update un if que permitía e la ejecución del movimiento si el personaje era por el usuario y negaba el movimiento si era de otro jugador.

This content is absolute GOLD TD. Thanks for all your efforts and sharing your knowledge. I've just dropped PUN2 to come over to Unity Netcode because I see it's pretty new in comparison and it's gonna have a lot longer LTS I'm sure than that of PUN2. I really don't want to have to learn Photon Realtime right now and Netcode seems way easier in comparison. Interested to see how I'll get on, but the concepts and the way you teach them seem pretty reasonable. Famous last words eh? :D

@Tarodev 3 месяца назад

PUN2 is an amazing product, and it actually handles a lot for you. For example, PUN2 is netcode + relay + lobby combined. Saying that, in my last mini project I still used netcode over PUN. It's simple and gets the job done. Good luck!
