[@jacobwoodman4488]

Hey everyone, if you don't want to lose 10 minutes like me at 8:50, be sure that you have Run in Background enabled in Edit->Project Settings->Player->Resolution & Presentation on your server, or else it won't run while tabbed out, making you think you messed up the movement implementation. Also not sure if I missed this, but you will also want to tag your player camera as Main Camera, so that Unity knows to switch to the player camera when you connect.

[@tomweiland]

It'd be good if Run in Background was enabled by default, although I suppose that could cause undesired behavior in singleplayer games.

I'm just glad people are finally actually using it 😅

[@not__nugget]

Super cool video! I admit I have lost pretty much all my desire to work on games ever since I got my job as a software engineer, but watching this stuff surely helps rekindle that inspiration. One suggestion I have so far is in regards to sending inputs, and is actually an issue which I was also attempting to solve in an elegant way. Instead of allocating a large array of boolean values (a collection of yes/no answers) you can send a single number which behaves as a bit-flag (or a collection of yes/no answers) that can be sent much easier and with much less bandwidth. Of course the complexity increases the more complex a game becomes, but thankfully this can be created and expanded very easily using enums in C#. By assigning the value of each enum entry to a power of 2 (up to the maximum value the underlying value type can support), you can not only send the inputs as a single number, but you can also set them explicity by type and name. At the end of the day, a bool array works wonders, especially for smaller games with already minimal transport loads, but I love looking for any way to optimize, and this is a phenominal candidate!

[@tomweiland]

Riptide's AddBools method actually already packs 8 bools into each byte, so you can use a regular bool array (which is definitely easier to understand for people who've never used bitshifting) and still get the same bandwidth efficiency as doing it manually. Of course, you can also do it your way-in some situations it may be easier to not have to deal with an array at all. Here's the code if you're interested: github.com/tom-weiland/RiptideNetworking/blob/b063398f96faa068534d3e1ea7591ae9a6f0080d/RiptideNetworking/RiptideNetworking/Message.cs#L391-L403

[@tomweiland]

Glad you're liking it :D

[@FICHEKK]

Hey, I'd love to point out that you might reconsider your message creation with "Enum" base class as method parameter for the following reasons: 1. Passing any concrete enumeration will cause a boxing allocation. 2. Nothing stops anyone from passing an invalid out of range value by using an enum whose integral type is int, uint, long or ulong (or even short/sbyte and using negative values). What I suggest as an alternative is to create an extension method on your enum as such: public static ushort Id(this MessageType messageType) => (ushort) messageType; Usage is very simple, but more importantly, is compile time safe: Message.Create(MessageType.SomeValue.Id()); Hope you find this useful and thanks for the videos! :)

[@tomweiland]

But why? The overload that takes in an Enum is just there for convenience-the Create method that takes a ushort as the ID is still there and accessible, so nothing is stopping you from adding that extension method if you want it. I don't see a reason to remove the method again, especially now that it's already in use and removing it would be a breaking change to the library...

[@FICHEKK]

@@tomweiland I understand the convenience, however, convenience is not always the optimal solution unfortunately. Since message creation is something that can happen hundreds of times per second, you are allocating a lot of unnecessary garbage for no reason. This comment was purely a suggestion of something you might have not been aware of. I am just saying that if you want your library to be faster and safer for your users, you should probably deprecate that method. At the end of the day, it is your library and you decide what's the best. :)

I'm really looking forward to your next video about movement prediction!

[@tomweiland]

Do you at least have some prior programming experience? Multiplayer stuff is quite literally the "deep end" of game dev, and although jumping straight into it with no experience building games isn't the end of the world, the learning curve will be extraordinarily steep if you're simultaneously learning the basics of programming, so just be aware of that. Either way, best of luck with your project :)

[@K3rhos]

Question here ! I'm making a game with a lot of entities, Player, Props and Vehicles, with a lot of high speed movements etc... Honestly I feel I would prefer to send position from clients to the server and simply send back infos to the all other clients (except the one sending the data), because it's less laggy this way from the client that actually drive a car for example, sending inputs is a good way to prevent cheating but add a lot of inputs lagg, so what do you recommend ?

[@tomweiland]

Virtually all fast-paced competitive games don't let the clients decide anything and only have them send inputs to the server, because they want to prevent cheating as much as possible. They hide the input lag that comes with that approach by having the client predict the server's response (while waiting for said response) so that something happens immediately upon pressing a key, and then once the client receives the response it reconciles its prediction with the newly received authoritative state to avoid desyncs. The concept is called _client prediction_ and there are a number of articles & videos out there discussing/explaining it. However, if you don't really care about potential cheaters, then it's a big waste of time to maintain server authority.

[@K3rhos]

@@tomweiland Okay, thanks for your fast answer, yeah my game is not going to be really competive, there will be minigames and everything with cars and other entities, but I feel it's cheaper, it's not going to be an FPS competive game, so I think I'm okay with the classic: Send client position -> Server -> Send back to other clients. I'm handling some stuff only server side, like the time of day, the current weather etc... it's all decided by the server and redirected to the clients.

[@zengakukatsu]

You make good videos, I am excited for client prediction tutorial.

[@tomweiland]

😅

[@Kristopher_Logan]

I took a different approach with my setup. instead of having a client and a server, the client and server are one program. in this way I have setup a client-server configuration where the player can be the host and clients connect to him/her the the server player information gets sent to connected clients just like any other player. works quite nicely actually and makes it way easier to test things since I do not have to juggle two projects.

[@tomweiland]

Yeah that works. There's also a demo project in the repo set up this way if you want to check it out.

[@inevitable.3991]

@@tomweiland Yes but doesn't that make it less secure since the server side code is available to the player?

[@tomweiland]

@@inevitable.3991 yeah, but if you want a client to be able to host a server, you have to give them the server code. Obviously if you just want players to create _rooms,_ you can still have your official servers running those, but if you're building a co-op game or something not-super competitive then you're wasting money to prevent cheating in a context where there's not much incentive to cheat 🤷‍♂

Hi. My character does not move on the Client side. But it acts on the server side. I couldn't solve the problem. What can be the problem ?

[@Enrique_editz]

Great Vid Tom, also how can I switch to the first person camera when I press connect, because the screen gets stuck there whenever I press it, thanks

[@tomweiland]

Does your local player prefab not have a camera attached? Normally whichever camera is activated last becomes the one that is visible-if that's not working you, you may have to add some code to disable the main camera when the local player is spawned.

[@Retr-eo5uz]

Hey Tom! I have a question, so I am using the PlayerHosted Config, so when the client updates it's movement it's smooth, but when the server-client does it, it takes like 1s for each update.

As I said in my response to your other comment (and in the video), just take the code in the Move method and replace it with whatever you want. How would you make movement in a 2D game? Literally just take that and put it in the Move method. As long as you call SendMovement at the end (and change the Vector3 that's being sent to a Vector2), you'll be fine from a networking point of view.

Does your bool's name have the same spelling & capitalization as in the animator window? If that snippet you posted there is copy/pasted from your code, then you have an extra closing parenthesis-it should be _.SetBool("IsMoving", true)._

[@Kristopher_Logan]

I used this to create a multiplayer server with a map editing system where the client side, if the logged in user is an admin or a builder, the can edit the game map and upload map objects to the server. I figured out a method for transferring mesh data from client side to the server using a multi-step uploading procedure. same thing for uploading map part location data. and downloading that data to connected clients. just need to setup the functions that turn mesh data into gameobjects and I can make a blank server, with the ability to upload gameobjects to it from a client logged into the server as an admin. Also made threaded saving and loading for server data

[@tomweiland]

Nice.

[@eleocraft278]

There is an error in the animator, on the transition from PlayerSprint to PlayerIdle: you checked two times for IsMoving, but never for IsSprinting. Minor error, just noticed. great tutorial

[@tomweiland]

Oh true 😅 Although it actually doesn't matter in that case because if the player isn't moving, he's obviously not sprinting either, so just checking IsMoving is enough.

[@thereborne5219]

what do i do if my game is based of moving by clicking? and not keys

[@tomweiland]

Client sends the target/clicked position to the server > server moves player in that direction > server sends position updates to clients. It's just a matter of swapping out what kind of input you're sending to the server.

[@sanaytyagi1125]

Great video and really well explained! I was wondering, when you are working with multiplayer shooting, would you make the code server-side or client-side. I was trying to implement it and i used client-side, but i’m not sure if that will bring any issues along with it, thank you!

[@tomweiland]

Either works, and which is better depends on your goals. Letting clients handle hit detection is easier, but it leaves the door wide open for cheaters. If you care about preventing cheating as much as possible, you'll want to have the server do hit detection instead.

[@ndrcreates_per]

How can we pervent code duplication in server & client? Networkmanager shares many implementations in both server & client. Shared library with inheritence maybe?

[@tomweiland]

You could use a local Unity package to share code & assets, but what's usually better is to have both the server and client in the same project. I just think that when first getting into multiplayer development, it's easier to understand the separation between server and client if they're in separate projects.

[@ndrcreates_per]

Yeah you're right, i think having the client and the server in the same project is the most valid approach and is going to be awesome when you define the server from an Rest API so we can know who is the server and who is the client on multiple devices. the thing i amazed by that is, How does the Mirror and Photon managed to create their tool and the unity server wont be necessary for using those solutions. @@tomweiland

[@gameranon]

@@tomweiland I think what he means is 3rd person. Where you can see your own character as well with animations. You have 1st person. Though should be easy to adapt. You would just need an animation controller on your localPlayer prefab setup the same way and then attach the script to local player as well. Since it's movement speed based animating, should just work. Will be testing myself. Good videos by the way and looking forward to #3

[@gameranon]

Also, animations should be triggered via server as well depending on the type of game you are developing as well. A fighting game for example or 3rd person type argp game. You don't want attacks happening without an animation or cheating via non-server oriented attacks.

[@inevitable.3991]

No, I think he means that the other players should be visible as human models instead of beans. This can be easily done by replacing the bean with the player model and replacing the animations with the imported human animations. I have done this in my project a while ago and it was very easy.

(tho this will be answered when i look at the source code)

[@tomweiland]

If you want players to be able to host their own servers you need to either give them access to the server application or include the server code in the client project. You don't have to do any threading for it to work, that's entirely up to you though.

Since the tutorials are really fast paced straying from them becomes really hard, as some things seem to lack direct explanation on what to do for side cases.

[@tomweiland]

I'm not sure I understand how "a dedicated c# server receiving messages" is an example of something "[lacking] direct explanation on what to do for side cases", or how the solution that you came up with addresses/solves the supposed problem... The server in the video receives messages-what "side cases" are you referring to that need more explanation? What does moving the players dictionary outside of the Player class do to help your problem?

All classes, methods, properties, etc. are technically documented via XML comments, which should show up in your IDE's intellisense. Maybe I'll write some more elaborate/"official" documentation at some point, but that probably won't happen at least for a few months because I don't have much spare time and it's not high on the priority list (since everything already has an explanation of what it does/how to use it).

Your code and tutorials are awesome. I have one question about this package tho, a lot of the games now allows players to create rooms where they can join in and play, and each room have a limit for the amount of players that can join that room. So i was wondering, how would you do that with this package? is it already implemented? If not, do you think it would be better to have that as the default? where the default would be 1 room and that would have the max limit of player, however the number of rooms can be increased. Or is that already implemented in the package?

[@bolagadalla]

Actually, now that i think about it, I can create a singleton class Rooms, which will hold a dictionary of string and Room. Room would have a list of connected players and a max of x players. and add a method to the EventHandler "ClientConnected" that would add the player to one of the rooms or specified room (if slot available). And just i would just use the "Send" method to Send to each player in the room.

[@tomweiland]

Yeah something like that, but keep in mind that if your game gains any significant amount of traction, you'll need to run multiple servers to handle all the players, so it may just be easier to have each server function as a single room.

I know this isn't related to the video, but how do I call a function in the client code from the server code? I have tried setting a bool and passing it on but there is a delay.

Send a message (no need to add any data to it) to the client, and then call the method in question from inside the client's message handler.

I Just wanted to Say that i really appreciate your hard work on this, i'm finishing my Mirror multiplayer game (which taught me a lot), and i started thinking about using your solution. I wanted to ask if it would be enough for bigger multiplayer games, or should I Just code my own solution?

[@tomweiland]

It should be enough for bigger multiplayer games, although that still heavily depends on how well you optimize what data you're sending and when. Obviously you're going to have a much better-running game (regardless of what networking solution you use) if you only send data to players that's relevant to them-for example, they don't need to know about where another player is if they're out of view distance (and they probably shouldn't know anyways, as that will make it easy to build cheats). Riptide is pretty fast, and I'm not sure if there's much that can be done to make it any faster than it is, apart from maybe getting into writing unsafe C# 🤔 Unless you want to build your own solution for the learning experience, I'd definitely recommend using something that already exists.

[@kreskot2]

@@tomweiland Thanks for the tips! I thought that I would need a networking that is "outside" unity, like your previous one (where things were printed in cmd etc.), but i think i'll give this one a try.

[@tomweiland]

Riptide is completely independent from Unity-there's a console app demo in the repo which demonstrates this. However, Unity also has a server build mode which strips out the graphics, sounds, etc. and basically just gives you a console app.

[@dmrdev9934]

one little question why are we using static void on messagehandlers?

[@tomweiland]

Message handler methods have to be static because if you made them instance methods Riptide would somehow need an instance of the class to actually call the method, and the return type has to be void because handler methods don't return anything.

I have an issue relating when new clients join the server. The scenario is a client joins the server and rotates backwards 180 degrees, then a new client joins that server, the first client that joined will now have their controls reversed. How do I avoid this effect.

[@tomweiland]

This doesn't happen in the demos or the sample project, so you must have done something differently-unfortunately I'm not sure what that might be. Your best bet is probably to compare your code to mine (you can find it on GitHub).

[@dashingwarrior3187]

​@@tomweiland​ So I launched the sample project and in it does not create the same problems as in my project. In my project at the beginning of each scripts I added the name of What project they where associated with, There's also only one Riptide networking and one Message Extensions script that the client and server share. I might have put the wrong script name in the wrong place, but would having only one Riptide networking and one Message Extensions script cause issues in this scenario.

[@dashingwarrior3187]

K I fixed the issue. I just took the needed code from the sample project, change the name of the scripts to my desired name for them and swap them for the ones in my project. I think just I put the wrong script name in the wrong place some where the first time. Also having only one Riptide networking and one Message Extensions script that the client and server share was not the problem.

Your videos are really helpful, but as a beginner programmer, I do not understand a lot of it. I was wondering how I could make it so that there is a single player option in addition to the "connect" option.

[@tomweiland]

That depends on your game. I'm pretty sure games like Minecraft actually run a local server when you're playing singleplayer, which is why it's possible to let others connect to you via LAN so easily. Unless you want to basically build a whole separate singleplayer version of your game, you'll have to do something like that.

Thanks for this, dead chuffed your releasing these tutorials and making the source code available! Just wondering if the server being a Unity client was best performance dedicated server you had in your travels or if its just ease of use for these tutorials?

[@tomweiland]

_"if the server being a Unity client was best performance dedicated server you had"_ In comparison to what? Obviously you could use a console app instead and build everything (physics, collisions, transforms, etc.) yourself and it'd probably be more performant, but it'd also be a crazy amount of extra work-trust me, I tried it and it sucked. You can watch my "2 years of game dev" video for more about that experience. It's honestly similar to deciding whether to use a game engine for a singleplayer game. You could probably squeeze out a bunch of extra performance if you built your own custom engine, but you have to ask yourself if that's really worth it. Do you want to build a game and actually release it at some point, or do you want to spend all your time building the engine and never getting around to the game itself? Multiplayer development is already inherently more complex and time-consuming, so at least in my opinion, a Unity server is good enough. The performance I'm sacrificing is well worth the saved time and effort of building literally _everything_ from scratch.

[@inevitable.3991]

When building the project from Unity, you have the option to make it a 'Headless build'. Which means it will act as a regular console app.

[@wils991]

I have an odd question to ask. I seem to be having an issue when running both the client and server. if I click connect in the client I have to click on the server for it to update, and same with movement I have to be pressing the keys then click on the server and the player will move. Has anyone else had this problem? I believe its to do with unity or windows.

[@wils991]

Update: it a setting in unity, I will link how to do it here for anyone else. answers.unity.com/questions/42509/stop-unity-pausing-when-it-loses-focus.html

[@tomweiland]

You need to enable "run in background" in the project settings. Unity seems to have changed the setting's default value for some reason-Unity 2020 has it enabled by default, but I think 2021 and newer versions have it disabled by default.

[@tomweiland]

Yes, what networking solution you use really has nothing to do with how many dimensions your game has.

[@TheRealBillyB]

@@tomweiland as a complete beginner to both coding and game design would you recommend me building my game using a style like this? or the steamworks and mirror style? I plan to release on steam to begin with and hope to expand later

[@tomweiland]

When I was first starting with multiplayer, I remember disliking UNet (Mirror is basically an improved, community-maintained version of that). When I tried Mirror several years later, I didn't like that either because it felt like it did too much for me, and as soon as I wanted to do something that wasn't officially supported, it became really complex and messy. However, by that point I was used (and addicted) to the freedom, flexibility, and control that solutions like Riptide offer, so I'm probably at least a little biased. Mirror may be more convenient and easier to get into, but in my opinion I'm not sure that's actually a good thing in the long run, especially if your goal is to _learn_ how multiplayer stuff works. What you choose to use is really up to you and what your goals are. Do you just want to build a small game that works asap? Mirror is probably the way to go, as long as you don't mind it doing a lot of things for you under the hood. Are you aiming for a much bigger/long-term project that requires more flexibility and control? Are you trying to learn as much as possible? Riptide (or something like it) will probably serve you better then. Much like Mirror, Riptide also has a Steam transport, so it integrates pretty seamlessly with Steam's networking. All that being said though, if you're really a "complete beginner to both coding and game design", I would recommend not touching multiplayer at all just yet. Getting into networking with no programming experience, no familiarity with Unity, and no understanding of how to debug & resolve errors is setting yourself up for a lot of pain and frustration. It's like trying to learn to swim, but instead of doing so in the shallow end of a pool, you go do it in the ocean on a day with 10-foot waves. It can probably be done, but it'll require a strong will to _actually learn_ (not just copy/pasting stuff and relying on others for everything) and a _LOT_ of patience, motivation, and determination, otherwise you'll just end up drowning (aka giving up). Building some small singleplayer games first would probably be wiser, as it allows you to familiarize yourself with Unity, learn basic programming skills, and encounter & learn to solve common errors on your own, without the added complexity of networking making everything 100x more difficult and confusing.

[@TheRealBillyB]

@@tomweiland I thank you for your advice and for the lengthy response. I have messed around with coding before but strictly following tutorials so I have like the super beginner understanding of it, same with unity. As for the multiplayer part, I know it’s probably not the greatest idea to start with but I have an amazing game idea that I want to capitalize on. My plan was to build something show worthy and find someone who knows networking better for the debugging parts of it but I would like to learn as well so it won’t be all “do this for me” Anyways as for right now I’d probably be better off with something that does more for me at least for the early build of the game so I might go with mirror just to start, I would love more control later down the road tho
