M2H unity networking tutorial 1

About this tutorial

I always thought Unity needed a proper networking tutorial. When I started unity networking the

networking example was a bit too confusing; A proper networking example should have

independent examples so you know where to look for something within seconds. With that in mind

I decided to join the UniKnowledge contest and finally give the community a networking tutorial,

This tutorial is written by Mike Hergaarden (“Leepo”) from M2H

(www.m2h.nl). We've been using Unity for over two years now, though

most of our unity development time has been spent in the past few months.

We've been concentrating on unity multiplayer since the very beginning. In

fact the first unity game we made featured multiplayer; it's that easy to add! Our multiplayer games

include: Crashdrive 3D, Cratemania, Surrounded by Death, Verdun Online and our current

upcoming multiplayer challenge is Hyberon.

Have fun going trough this tutorial. If you made something exciting thanks to this tutorial, let me

know!

How to use this tutorial?

Combined with this document is a zip file containing the unity project which is used in this tutorial.

It is assumed you have already made yourself familiar with the unity editor and basic scripting, if

not: check out the unity (video) tutorials.

Multiplayer isn't much fun to debug since you need to have two instances of your game running

“Edit → Project settings → Player” .

Tutorial 1: Connect & Disconnect

Let's get you going!

• Open the very first tutorial scene: The scene can be found at “Tutorial 1/Tutorial_1”. This

scene consists of one camera, one gameobject with the Connect script attached to it and one

gameobject to display the scenes title.

• Build a webplayer and run it.

• Start the scene in the editor as well and click on “Start a server”

(using the default values for IP and port)

• Click on “Connect as client” in the webplayer.

• You should now see “Connection status: Client!” and

“Connection status: Server!” on your two instances.

input from the GUI field, these values are used when pressing the button to connect. The GUI

function is divided in four parts; For servers, connected clients, connecting clients and for

disconnected clients. We use the provided networking status “Network.peerType” to easily check

our current connection status. We call the Network.Connect function to connect clients to servers,

this function takes IP, port and optionally a password as arguments. TO start a server a similarly

easy function is called: Network.InitializeServer. This takes a port and maximum allowed number

of connections as argument. Do note that you can always lower the maximum numbers connection

on a running server, but you can never set it higher than the value you used when initializing. You

need to keep one more setting in mind before connecting to a server or when initializing a server,

that is the “Network.useNat” bit you see just above the corresponding connection/initializing code.

Now, on to the last bit of code in the file; The +/- 10 functions that are automatically called by

Unity. It is important to note that you don't need any of these functions anywhere in your code if

you don't want to use them, you can remove them all and this demo will still work. The first 6 client

and server functions should be very self explanatory; They are called on only the client(s) or only

the servers. If you want to use the parameter passed by the functions, checkout the unity manual

entries for these functions.

The last three functions are different. OnFailedToConnectToMasterServer is called on a client

when you somehow can't connect to the masterserver, more details about the masterserver will

follow later on. OnNetworkInstantiate is called on instantiated objects, we'll also have a look at
