Is making a server better using riptide or using your old networking tutorials code?

[@enderduck4253]

@@fortnitegiftcard8541 definitely Riptide. It's like he mentioned in the video. Riptide is cleaner and easier to work with. And a test conducted a while ago showed it to be 10 times more resource efficient than the previous solution.

Yeah Riptide is free to use, but keep in mind that renting servers (which you'll need to do for any sort of public release) will still cost you money, regardless of what networking system you use.

Hey Tom, I've been following you for 2 years now and your content just keeps getting better and better! Whether the videos, or the multiplayer solutions! Riptide is fucking awesome!

[@tomweiland]

Thank you! I'm always looking to improve the work I do-glad you like it :D

[@spidernh]

I like how this solution seems like a balance between your old solution, where you had to write everything and I didn't understand it, and Mirror, where I could understand it easily but didn't know exactly what was going on since I wasn't controlling everything. I'm excited to see more of this series!

[@tomweiland]

Yeah, I feel like Riptide is a good middle ground between the two. It saves you the pain of writing the really low level network code (which you most likely wouldn't ever need to modify anyways), but leaves the higher level stuff up to you so that you're fully in control of what's going on.

[@FlubsYT]

[@Kristopher_Logan]

I got my ServerClient Configuration working, and trasmitted by first message to the server. I already had a setup going called UML that I am using for Educational Content. You tutorial really helped me alot - now I just need to set things up so there are two message types, client and server. messages from clients need to be blocked from accessing server functions. since it all uses my UML system, I just need to setup a dictionary that checks for keywords that clients are not allowed to use - such as shut down server commands and whatnot. I already have most of the stuff done, its just networking that needs to be completed, and thanks to this, I am way farther ahead. I had used riptide in the past in an effort to make an RPG maker with online features. the rpg maker failed, but riptide did not. hence why I am coming back here again to use it. Thank you for such a great tool.

Perfect timing for starting up this new multiplayer networking series! I recently built my gaming pc so I'm back up with Unity game dev. I can't wait to see what you'll make with it. Good touch on showing if you're either working on the Server or Client project/code. Huge improvement in quality compared to your previous tutorial series!

[@tomweiland]

Yeah, it's an upgrade on all fronts. The code is better and so are the videos :P

[@K3rhos]

Exactly what I needed, I'm coming back after like 3 years without working with Unity, and I recently wanted to do some networking, I just took my old networking code from your old tutorials and slowy tried to remake everything properly, fixing issues and stuff, and I quickly became to conclusion: "This thing is garbage lol !" I have a lot of performance issues and everything with the old net code, issues when disconnecting, time out issues and more. Since I'm making a complexe game that manage a lot of entities at the same time, I need something stable and efficient ! And I just saw your new tutorial, and I don't wanted to go with Mirror or other stuff like that, Riptide seems to be exactly what I wanted.

[@phee3D]

even the tutorial itself makes a lot more sense than your previous series. What I mean is, in the previous tutorials it was more of a "follow what I'm doing" kind of thing with explanations sprinkled in here and there and many people who weren't interested in understanding how the code works or didn't have enough knowledge to understand how it works didn't have a great time. This makes a lot more sense because now you're just showing how to use your multiplayer system instead of building it and anyone interested in understanding how it works can just read the source code. Big brain move right there

[@tomweiland]

Yeah, I didn't do a great job of explaining things in the old tutorials, and they (especially the earlier ones) were much too fast. This is definitely a major improvement on all fronts 😅

[@vintoncerf7562]

Note to all new viewers: Server.Tick() method was replaced with Server.Update()

Personally, i think a video explaining the methods that rapid uses in detail would be really cool. It will definitely help with solving more complex problems.

[@tomweiland]

You mean you want an explanation of Riptide's internals? That's unlikely to happen-it'd take forever and most people wouldn't really benefit much from that knowledge (because they just want to get on with making their game). The source code _is_ pretty well commented though, so I think you could probably make sense of the majority of it without a video explaining it all.

[@chrisfonte4987]

Interesting. I’ve been following your other networking tutorials, is this going to be a similar series? And if so do you think the previous tutorials are going to be helpful still?

[@tomweiland]

The previous tutorials might be beneficial because you'll be writing all the low level code yourself. On the other hand, I didn't do the greatest job at explaining all that so it may not actually help you learn anything. In this series we don't write the super low level stuff and just stick to what applies to the process of setting up mechanics in a multiplayer environment, so these videos will probably also be more beginner friendly.

@@tomweiland Thank you!

[@MaxIzrin]

Works well, thank you. Couldn't get the Message Handler to work, kept saying there's no handler for the given ID. Got around it by using the message received event, on client. Nice and simple over all.

[@tomweiland]

If it's complaining that there's no handler for an ID despite you definitely having a handler method set up for that ID (with the attribute), the method's parameters are probably incorrect. Server-side message handlers are defined by having two parameters (a ushort and a Message instance) and will only be detected/used by Server instances. Client-side message handlers are defined by having only one parameter (a Message instance) and will only be detected/used by Client instances. What probably happened is that your handler method was supposed to be for the client side (or vice versa) but didn't have the appropriate parameters and was therefore not used.

[@lukass1604]

I don't know if you've already done this in newer versions of this framework but you could wrap your Client.Connect method which takes a string with another method. Then you would avoid the exposed string parameter. Something like this: public void ConnectClient(ushort ip, ushort port) => Client.Connect($"{ip}:{port}); then only expose this method.

[@tomweiland]

I mean you can wrap it yourself if you like, but Riptide's connect method won't receive a wrapper like that as not all transports take an IP and port as the host address. For example, the Steam transport needs a Steam ID to connect to-a wrapper that takes an IP and port wouldn't work for that at all.

[@RasmusLeonid]

For some reason, I was skeptical at first, but I'm glad I started using riptide instead of the old solution. it's so much better to work with. Also, I noticed if I had two clients/projects running at once with the old solution, if I wasn't tabbed in, the game would run at like 1FPS, which made testing on one machine very annoying. Idk if that was caused by the networking, but one of the first things I noticed after implementing riptide, was that I no longer had this issue. Also nice that you're working on a transport for steam. Another cool thing would be a transport for epic online services, since(if I understood it right) they offer pretty much the same features as steam, but it works independent from epic launcher and is designed to work on literally every platform.

[@straightafitness]

i have a question: is there a player that has a specified client that is host and not a server?

[@tomweiland]

I'm glad you're enjoying Riptide! I've added the Epic transport to my things-to-look-into-eventually list, but I have no idea how soon I'll get around to that. I'm also not sure how that would work considering Riptide is built in C#-is there a C# API/wrapper for their online services stuff? _"if I had two clients/projects running at once with the old solution, if I wasn't tabbed in, the game would run at like 1FPS"_ That's very strange...my initial thought was that maybe you had the Run in Background option disabled in one/both of your projects, but if that was the case it should stop completely when you tab out, not run it 1fps 🤔 The old networking solution is/was substantially slower than Riptide, but unless you've got quite an old computer, I don't think the networking solution alone (in otherwise equally performance-intense projects) would make a large enough performance difference to go from 1fps to no noticeable lag...

[@RasmusLeonid]

@@tomweiland Sweet! EOS has a C# SDK but their documentation is far worse then the one from streamworks, and there is way less information about it from what I could see. Maybe that's just because I'm somewhat used to the steamworks stuff now though. About the 1fps thing, I'm also having my doubts that it was caused by the networking alone, but at least I don't seem to have the issue at the moment.

I'm not sure if this is already mentioned in the tutorial but in case you are experiencing a bug where the server/client isn't sending messages when minimized just add this line of code in the start method of a script: Application.runInBackground = true;

[@tomweiland]

You can also set this in the project settings and avoid having it in the code. The reason it's not mentioned in the video is because in the version Unity that I was using it was enabled by default-it seems they've changed that in newer version, which is odd.

[@CiarantDev]

stupid question but is there a way to play with other poeple without using port foward ?

[@tomweiland]

A lot of games run relay servers and have the servers hosting games, so even when you click "host" and it _seems_ like you're hosting the game, you're technically not-you just have get special permissions that allow you to change game settings and stuff. You can also use relay services like Steam's networking.

[@phee3D]

Hey Tom, a question: in the rudplistener class I noticed that you are constantly listening for messages in a while loop. I tried to find when you break it but it seems you don't break it as long as the connection is required or if there is an error. If this is true, does it mean that every single player in the game will have its own separate rudp client on the server which is constantly listening for packets from that player, hence having a separate thread for every single player? and if that is also correct, does this mean this only works because you run the Receive packets loop on a separate thread? since otherwise it would freeze the whole application if you do it on the main thread.

[@tomweiland]

No, RudpClient contains client-side logic for clients and is not used at all by any server-related code. An RudpConnection instance is used to represent each client on the server-side, but that doesn't inherit from RudpListener. RudpServer inherits from RudpListener and runs a single receive thread for _all_ connections.

[@phee3D]

Sorry to bother you. ive finished this first tutorial part for making this mutiplayer game. Everything is working fine but when the client disconnects from the server.

Also when i put in AddUShort and AddString on the Player Script on the server side it gives me errors so not sure what to do for that.

[@tomweiland]

If I remember correctly we address the player not being destroyed in the second video. As for the errors you're getting, if you need help with those I recommend joining the Discord server and asking there-troubleshooting here in the comments is a pain.

[@d0c_dev]

hey so my project has got to a point that having 2 separate projects is really hard to maintain, how would i go about merging the server and the client into a single project, how would i go about managing the scenes as the server uses a type of scene and the client another one

[@tomweiland]

If you're building a player hosted game, take a look at the player hosted demo in the repo.

[@elaivelite]

It's amazing to find so quality tutorial! Thank you so much! I have a question: why Riptide, not Photon you choose?

[@tomweiland]

I've never used Photon, but the idea of having an arbitrary CCU limit imposed on me just for using a certain solution (even if you host your own servers) doesn't really appeal to me. Also most of the people I've talked to who have used Photon said they didn't really like it 😅

[@arshpreetsingh5186]

Can you please provide documentation for Riptide

[@tomweiland]

In case you don't know, everything _is_ documented and explained via XML doc comments (which should also show up in your intellisense when hovering over stuff), but yes, putting all that onto an actual site is on my list of things to do.

[@arshpreetsingh5186]

Thanks 👍

I have created a fps game and It works really great . Thanks and great work.♥️

Hello, I am having a problem connecting by putting an IPv6 address as the client IP. I got this IP by using a script and it gets device IP automatically, but instead of debugging an error, it debugged a message showing "Connection to server failed". Do you know how to fix it?

[@tomweiland]

Can you connect if you manually enter the host computer's IPv6 address? How does your IP retrieval script work? Are you sure it's retrieving the IP of the host computer and not the IP of the computer it's being run on? I'd recommend joining the Discord server and asking about it there, the KZbin comments section isn't really suited to this kind of question/discussion.

[@MrIndiemusic101]

Out of curiosity does riptide support something similar like fishnet's network animator? How are you using riptide to manage animations of characters or is that handled client side somehow.

[@tomweiland]

Riptide is a much lower level library than Fishnet, and as a result there are no built in components that "magically" synchronize parts of a project for you. I admittedly also have not dealt with animations _too_ much in my own project, but so far it has been mostly sufficient to ensure other parts of the game state are synchronized (and then the animations can be played based on that), though in some cases I do sync specific animation-related data.

Awesome ❤️❤️, can't wait to see next part 😁

[@PowerSkor]

Thanks for the awesome video! Small question, Unity released Netcode for GameObjects, is this a better alternative or when do I want to use this instead of the Unity one? Your solution is a dedicated server instead of the Unity one where it seems that the server is also inside the client project, which is annoying for larger projects? Also how secure is Riptide for eg people trying to hack and send fake messages to the server.

[@tomweiland]

Riptide and NGO aren't really comparable as they operate at quite different levels of abstraction (NGO is far more similar to Mirror than to Riptide). Riptide can be used to build a dedicated server or a client-hosted game, and as far as I know, NGO is capable of both of those things as well. As for security, Riptide is basically as secure as you make it-out of the box it doesn't deal with session tokens or anything like that.

[@lgent2435]

Hello, is there any tutorial to make Riptide's RPC, client-server prediction, lag compesation, and reconciliation?

[@tomweiland]

Not that I'm aware of, no.

[@mary-os]

Hey, just wondering, could people steal all my data -- including IP, location, etc -- with this?

[@tomweiland]

Anyone who connects would be able to see the IP of the host computer, so yes, if you host the server(s) on your personal computer, people would have access to your IP. However, that's not something you want to do for a released game anyways because then you need to have your computer on 24/7 and eventually (if your playerbase grows) you wouldn't have sufficient processing power to run enough servers. This is just how the internet works though-if you visit a website, you can see the IP address of that website, and the webserver can see your IP too. The solution to this is to use cloud hosted servers so that people can connect without getting access to your personal IP, _or_ if you're releasing your game on Steam, you can take advantage of Steam's free relay system to mask your IP (like a VPN).

[@ethankuhrts2799]

Seems great so far, one thing I've been wondering since your previous networking solution, is there a way to run a client and a server in the same instance at a time for example someone may want to host and play at the same time and let friends connect to them. are there any big complications to changing to that sort of setup on my project?

[@tomweiland]

I actually just added a player-hosted demo project to the repo the other day: github.com/tom-weiland/RiptideNetworking/tree/main/Demos/Unity/PlayerHostedDemo However, it's making use of a feature (the auto message relay stuff) that will be in v1.2.0 (hoping to release that in the next few days) but which doesn't exist yet in the current version.

[@honakna2117]

I am new into networking in C#. I have only used Photon before and I didn't like it for the same reasons you said, If I want to test it with someone else what will i do with the server? Will i build it or leave it like that and what will the other ones do with server? Sorry for asking a lot of questions but i really don't know😅😅

[@tomweiland]

You can build the server or run it in the editor. In order to have a friend connect from a different network, you'll need to portforward the port that the server is listening on (in your router settings) and then change the IP that clients connect to to your public IP.

[@honakna2117]

Meaning that the server should be always running on my machine right? Cuz i really want to use Riptide

[@tomweiland]

If you release your game, you'll always want a server running (otherwise players wouldn't be able to connect and play), but you definitely don't want to do that on your own computer unless it's only your friends/people you trust playing. Even then, having your computer on 24/7 is suboptimal, so you'd most likely want/have to pay for server hosting.

[@honakna2117]

Thanks alot♥️

[@eleocraft278]

Is it possible to use riptide to make a localhost game like most multiplayer survival games (and for example muck from Dani)? Or do I need to pay for servers

[@tomweiland]

Yep, you can build lobby based games with it, and if you want to avoid server hosting costs you can use something like Steam's relay services (which is what Muck does). You'll need Riptide's Steam transport if you want to do that though, and like I mentioned in the video, it's functional but still in development: github.com/tom-weiland/RiptideSteamTransport

[@eleocraft278]

@@tomweiland ok thanks, this is exactly what I wanted to know. Looks like I will be using riptide for the game I am working on 👍

[@StarriApps]

This is really awesome! Really looking forward to the complete series! Is this udp or tcp based or both? 🌟

[@tomweiland]

Riptide's default transport uses only UDP.

[@enderduck4253]

It's RUDP or Reliable UDP, so you're retaining UDP's speed but you can still send information reliably if you need to.

[@Nervniyak]

How would you proceed with making Host&Play option? A lot of players have no idea what dedicated server is or how to run it. How do we implement it while having client and server as 2 different projects?

[@tomweiland]

You can combine the client and server code into one project if you want to allow players to host games.

[@Nervniyak]

@@tomweiland But how would you do that, if you already have dedicated server project built with it's own "mindset". Are games really built as one project for host&play and dedicated? I saw that unity's sample FPS has custom tools to create different builds for client and dedicated server from one project. But it was beyond my comprehension. And I remember Unet which allowed to host and join out of the box. Because general gamer doesn't know anything about hosting dedicated server all they want is to buy game in Steam, launch it and press Host (to Host & Join via Steamworks). Dedicated is good for games where regular players are not supposed to host lobbies.

[@tomweiland]

Take a look at the PlayerHostedDemo in the RiptideNetworking repo, or at the example scene in the RiptideSteamTransport repo.

You're a real genius

I'm not sure about that 😅

[@matheusdev726]

Could you please add a matchmaking system to Riptide Networking?

[@tomweiland]

That's kind of out of the scope of a networking library like this, so most likely not (at least not any time soon).

[@matheusdev726]

@@tomweiland It is a room system where only players who are in the same room will have the data synchronized 4 years ago Kevin Kaymak posted a video showing this matchmaking system

[@Errors404]

What type of game is Riptide best for? Will it work well with fast pace shooting game efficiently? Should i learn the previous tutorial which is said to be outdated to know the inner workings in case i wanna tweak or make my own? or is this tutorial enough for any customization?

[@tomweiland]

Because of how low level it is, Riptide doesn't really have any particular strengths or weaknesses when it comes to game genres. You can pretty much use it for any type of game. Riptide was a full rewrite of the internals, so while the old networking tutorials may teach you a thing or two about socket networking in general, it's not exactly going to give you a thorough understanding of "the inner workings" of Riptide (could still be helpful though). This tutorial series will show you how to use Riptide-if you want to understand the internals you'll have to dive into the source code but everything is pretty well documented/explained, if I do say so myself 😅

[@Errors404]

Thanks man. I really appreciate you replying to every comment here and clearing doubts (I personally wouldn't be able to😂)

[@famoviem4157]

Yeahh ❤️ Thanks tom. Quick question, in this series you'll implement create room? if don't, it possible to implement create room using this series? anyway thanks for this 🙏

I don't think I'll cover lobby systems in this series, but it's definitely possible to implement that with Riptide.
