UniKnowledge entry: Unity Networking the Zero to Hero guide

leepo i have a question are you still gonna update the networking scripts or are you gonna let it slip

because your project in unity 2.6 was beast and now i try to get it to work but cant get it to work i like the old idea of making a server on a pc so anyone can make a server i like to see that back in your new upgrade

thats the reason why i love that project i have also use smartfox sever for another project but your project is nicer so every one can make a server not only the maker

please make that back and i hope that you have the shooter function back because those 2 reasons is why i love it a online shooter

let me know if that is comming back again

and is there a way to make your old project work on the unity 3 let me know what i have to change to get the Network.useNat function

or give me a hint so i can make it work again thanks for reading greets dr-mad

 

NAT does work in U3.... master server also works..... if you know what you are doing, playing around with his tutorial even in the old 2.6.1 state in U3, a few changes should allow it to work. It is a solid base to use.

 

Hello. I'm using Unity 2.6 and every tutorial so far has been working, but when I get to Tutorial 2B, when you are suppose to be able to control 2 different cubes, the client's cube won't move. I can only move the server cube.
I built and ran the scene in the webplayer and then ran the scene in the editor and started a server there and then connected as a client in the webplayer just like in previous examples. Both the cubes are showing and both server and client show the correct position and movement of the server cube. But the client cube simply won't move in neither the client and server.
Can anyone please help me with this problem?

 

Hi all, thanks for all Posts. The new forum wiped my notifications so i missed some Posts here.

I'm still in Montreal ATM but I will be updating the tutorial for unity 3 asap and upload it to the unity store as well. Furthermore I recently made a networking helper class that I'll upload as well. This helper class adds some more custom made networking features.

 

Great with update for Unity 3!

 

Really nice tutorial Leepo. Would be nice to see all scripts in C# too.

 

As I'm going to author it for 3.0, I will be converting it all to C#.
Not sure if I should keep JS support too? I guess so, even though it's a pain to me .

 

Hi, i am familiar with unity but am still very new to the more complex stuff (including scripting) let me first say, the tutorial is incredible and i owe you so much for making it, but none of the scenes in the project are "put together" so to speak, none of the scripts are attached, none of the materials are attached to objects etc. i'm not sure if things are supposed to be like this or not but the tutorial lead me to belieave that the examples were pre-made, please help me

 

mellow991: Nope that's not OK. the entire project should run out of the box with everything working. You are on 3.1 I assume?
I am going to revise the entire tutorial for a Unity store release in the next few days.

 

Im on 3.0

 

Yes please, keep JS support.
Thank you Leepo.

 

View attachment $Example2.rar
Example2 on C# for 2.6.1. Array like List<T>, runs significantly faster and requires no sorting, for 3.0 to modify a bit NAT. Hope this will help you. And many thanks for code.

 

heya Leepo,

Have you decided if you will keep a JS version - it would be great if you did.

Cheers

Jeff

 

Yeah sorry for the doubt/confusion guys, I'll keep JS as main language and offer C# conversions as well.
So far I've added 1 extra example, new lobby code, a new main menu (host/join-direct/masterlist/quickjoin) and a reusable networking class that makes connecting masterserver stuff a lot easier (adds retry feature and custom timeouts etc.)

 

wow klinkt als goed werk

thanks for the great work

is there gonna be a shooter element to???

nice options you have now when are you think its gonna publish?? i use your template last time and i change alot of it to make it work but is that ok to do

im just asking can i modify it for friends to play it

im looking forward to it

 

Leepo you are a Legend! Your new example is exactly what I am working on at the moment and cant wait to see how you have implemented it. I am mostly hacking your old examples to pieces with some added spice from the new U3 scripting reference.

May I ask for a timeframe when you are looking to finish the rewrite up? Not to pressure you or anything

 

looks usefull. But I couldn't use it. It is because of the older version ( probably hear that one before) But Ill keep checking. Happy scripting!

 

I've tried certain unity networking games, and either noones online, or they don't work; but Red Crucible is astounding! How would one go about making something similiar to Red Crucible in every way but game play? (Instead of tanks, make it FPS, or RTS, or what have you.) What's the caliber of networking in your tutorial?

 

Looking forward to the update as a c# user who wants to get into Unity networking.

 

Yes! I got the examples to work. You just have to remove the 2nd and 3rd pragma's. After hat the tutorials are quite worth it. Just one thing, is there anywhere you know where people can get more into depth about wireless multiplayer (LAN)?

 

Wireless multiplayer (proxy)? That doesn't make much sense, please clarify yourself.

Furthermore proxy is a wide subject as well; what do you want to know about it? You can run a proxy to proxy all unity networking traffic via your own unity-proxy server to ensure everyone is able to connect to eachother. You can not use that proxy on both the server and the client though.

 

Sorry, I had changed proxy to LAN, I know that's anoying but in that hour I learned that proxy was much mre complicated than LAN.

 

heey how is this project comming along can you say how far you are and what you have for the 3.x versions ???

im really waiting till it comes out please reply to this

your the greatest

groeten dr-mad

 

Thanks! This is brilliant - but...
Whenever I run any scene, I get errors: "unknown pragma: 'implicit' " and "unknown pragma: 'downcast' ".

Any suggestions as to why this is?

Many thanks,

Arthur

 

Oh,

Note that I'm using the latest Unity version except 3.0 - 2.6?

Thanks again,

Arthur

 

Hi, just noticed this thread as I start to look into multiplier 'how to'.
I think your tutorial would be great for me. Will it work with the latest 3.1 version of Unity3D?

Cheers

 

The current online version will work (on 2.X and 3.X), but has some rough edges (#pragma implicit and downcast are added by Unity). Furthermore it doesnt cover the new NAT stuff.

I have a greatly improved version for the unity store in the works thats aimed at Unity 3.

 

What is a pragma anyway?

 

cool can't wait for the Unity 3 version of your tutorial
thanks for the info

 

Thanks,

If I built the game should it run correctly? Anyway, this is epic, and has greatly helped my game.

Arthur

 

Thanks for the tutorial, it's helping me a lot.

It is in dire need of a copy editor though. For instance, what exactly does this mean?

Code (csharp):

1. the script is now not always only run by the objects networkview owner

"Now not always only run"?

I'm also having trouble understanding the code because the client and server code seems mingle and overlap in places. For instance, there's an RPC function called "SendMovementInput". Simple enough, but then you call it directly from server code which makes it betray its name (There is "send" in the name but you're not sending anything over the network). This makes it confusing.

You also have ambiguous statements like this comment in the code:

Code (csharp):

1. //Call an RPC on this new networkview, set the player who controls this player

I think you should make an effort to distinguish between a player as in NetworkPlayer and a player as in a user playing the game.

Unless I am misunderstanding something, but even then I hope this helps you make this more clear.

 

That sounds awesome. Any ETA on when it will be complete?

 

To test the Asset Store I've uploaded a improved (and now integrated) version of my JS -> C# converter yesterday. The asset store seems to be running now so I expect to submit the whole new Unity networking project next week or the week after.

 

Hey

Couple of questions

How can you do this conversion in C#

var playerNumber : int = parseInt(newPlayer+"");

Also

Rigidbody createdCraft = Network.Instantiate(aircraft, new Vector3(-3798.679f, 131.9899f, -5415.493f), new Quaternion(0,0,0,0), pId) as Rigidbody;

createdCraft.networkView.RPC("SetPlayer", RPCMode.AllBuffered, p);

gives me a Null Object reference, any ideas?

 

Awesome. You are my hero. Will it include a PDF like the original zero to hero guide?

 

Mike, Do you have a good example on the use of 'groups'?
I have tried various things based upon what I see in the online docs but am not able to isolate messages to groups when sending RPCs. Even when I have the server set the clients group using the incoming NetworkViewID and set it in the client.. ..the next call RPC call to that group goes to all of the clients..

Any help would be appreciated?

 

Yes, it's an improvement to the previous tutorial.

twoopy:
I have no group examples as of yet, but have worked with it in the past. Hm, grouping should work and I believe you only need to assign the groups on the server. Then again to be sure you better assign them on both client servers to test.
Note: SetScope does not work on RPCs, but groups should.

 

This tutorial was gold, Im just having issues intergrating it into my game (I should work them out over next few days hopefully) Maybe with the next updated version include multiplayer in something other than a FPS start. And what Price range are we looking at? Im Interested , Going to by your converter next pay.

 

Thanks.
I am thinking of a 50-100€ price range for the complete project, suggestions are welcome.

 

I could probably do a 50€ - 70€ or more depending on how brilliant it is. (And if it is very drop inable sort of thing).

Either that or you could go with something like 30€

Though it would deffinitally have to work with something other than FPSes example wise. My game is fully 2D.

 

70€ is very good price

 

Your tutorial has helped me understand networking more than anything so far, but I am still getting errors on my script. I am posting a beta site and the script and a jpg of the the errors at TurtleWolf.info. I am thrilled with my progress but would appreciate any help getting a second player into my reality.

 

Can anyone guide me to a good SmartFoxServer/Unity3.0 guide?

 

this is really hatefull

charge money for a example first it was free now its 50-100 euro

eerlijk vind ik dit nu een klote example ik ga hem niet kopen


sorry but i hate to hear that it now cost money im looking for another way

then il go for the smartfoxServer its alot better then this and that is worth buying more options and more functions

serieusly i now definitly step over to a smartfoxserver that has the new fps example with accounts and other stuff

or i go work on my mmorpg some more with smartfoxServer

 

look on the smartfox site it has a new example for 3.x and there you must ask the questions here almost nobody know how the scripts work and try using the documentation on smartfoxserver site

that is better to try i use the fps example from smartfoxserver 2.x that is for unity 3.x and before i use the 1.6.9 version with unity 2.x but there i make a new mmo now im converting it till it works on 3.x unity

just look for the extensions to make it better

 

Leepo, thanks!

 

Your tutorials where a good start, I finally got what I needed. Anyone reading this might also want to look into the unity multiplayer tutorial and the post called from lan...to wan (or man) the last couple posts should help you figure it out.

 

Leepooooo..... When's the premium version coming to the asset store?!

 

Can't wait for the new 3.0 tutorial. I just recently got into networking for Unity and started using your first tutorial project after discovering that Unity's Networking Example wasn't working right for Unity 3.0.

Anyway, great job with the current tutorial and I can't wait for it to appear in the Asset Store (hoping that it is leaning towards the $50 end (or maybe even $30, lol)) I'll still buy it regardless.

 

Any news on this???
