Description:

This is a revamp of sourcenet, a module designed to expose Source's networking.

Notes:

- All allocated objects (sn3_bf_write, sn3_bf_read, UCHARPTR, dataFragments_t) must be freed, see examples.
- Do not call :FinishReading/Writing on bit buffers passed as arguments, only free objects you create.
- If you're not using the hooking base, always detach from functions before you change level. Not doing so will cause a crash.

SVN:

http://christopherthorne.googlecode....gm_sourcenet3/

Includes Windows and Linux binaries, as well as the source code and examples.

Global Functions:

-- Server: Retrieves specified player's net channel

I'll update this post when it's released

Another freaking brilliant module. This probably means nothing coming from me, but well done.

Where can we find how the different messages are structured? Didn't valve have an online repository of the SDK code too? I can't find it..

The messages aren't in the SDK. Take a look at sn3_base_netmessages.lua for structures.

[ColdFusion]

include( "sn3_base_incoming.lua" )
local convar = CreateConVar("disconnect_msg", "Disconnect by user.")

FilterOutgoingMessage( net_Disconnect, function( netchan, read, write )
	write:WriteUBitLong( net_Disconnect, 6)
	read:ReadString()
	write:WriteString( convar:GetString() )
end )

Custom disconnect msg. aka change "SomeFaggot disconnected(Kicked by admin)" to "Somefaggot disconnected(Suck my donkey dick)"

( should probably say that you run this clientside, and that the people in the server see this when you disconnect.)

Doesn't work. Because it detaches before the disconnect msg is send.

[ralle105]

Am I just being stupid or could you not free the allocated objects in their __gc metamethod?

Sweet module either way

[Flapadar]

Awesome.

That would cause objects passed as arguments to be deleted when they shouldn't be + there's not really any reason to use the garbage collector.

[Chrisaster]

I've fixed some problems in the base code for the next revision, however I'm having trouble with hooking since the last engine update. Currently looking into it.

[Chrisaster]

Fixed. The problem was caused by GetData returning a pointer at a byte offset, which caused problems when the previous data (before the net messages) wasn't a set of complete bytes.

[mr.wolf]

Quick question. As per Chris' code above, it is possible to detect the disconnect msg a player would normally transmit, and modify it as you want, however is it possible to modify the player's name as well?

SomePerson disconnected (random reason)

Becomes

SpecificPerson disconnected (reason to be determined)

Also, how would you read what a user's disconnect reason was and respond to it?

To modify the player name you would have to hook the svc_GameEvent message (outgoing), but I haven't added a wrapper for that yet. As for reading and responding, you can probably just add an incoming filter for the net_Disconnect message using the base code.

At first i thought the addon was gm_skynet3

I've added the necessary functions to parse game events in revision 6.

include( "sn3_base_gameevents.lua" )

hook.Add( "SendGameEvent", "ChangeReason", function( netchan, event )
	if ( event:GetName() != "player_disconnect" ) then return end

	local reason = event:GetString( "reason" )

	if ( reason == "Disconnect by user." ) then
		event:SetString( "reason", "Disconnected after " .. math.floor( netchan:GetTime() - netchan:GetConnectTime() ) .. " seconds" )
	
		return event
	end
end )

The name displayed is calculated using the "userid" key, so it won't be as easy to change.

[mr.wolf]

Would it be possible to combine this with the normal user disconnect hook? Use sourcenet to find the reason for the disconnect, and pass the string off to the player.disconnect hook to display whatever you want?

Does this take place prior to the player.disconnect hook?

[mr.wolf]

Where are you reading the reason they disconnected in there?

If the hook chris used above gets executed before the player.disconnect hook, then I can just assign the reason to a var and read it in the disconnect hook. Then I can print out whatever I want, in addition to the reason.

What I am trying to do is alter the player's name, but keep the reason intact. Also, it would be cool to respond to reasons, but with chris's example above, I can do that. I only need to know which hook is executed first. I can experiment, but I don't have access to gmod at the moment.

[Chrisaster]

include( "sn3_base_incoming.lua" )

FilterIncomingMessage( net_Disconnect, function( netchan, read, write )
	local reason = read:ReadString()

	write:WriteUBitLong( net_Disconnect, 6 )
	write:WriteString( string.reverse( reason ) )
end )

Client "Chrisaster" connected (192.168.1.9:27006).
Dropped Chrisaster from server (.resu yb tcennocsiD)

This will change what the server sees the reason as too. Use the previous example if you just want to change what other clients are sent.

Edited:

This won't work if you kick the user.

im not sure if i understand what this does exactly, but it seems like its pretty useful. lol i think its used to transfer data from the client and server.

anyone wanna give me an example on how to use this? lol

So I tried to use the module on my Linux srcds today...

error loading module 'sourcenet3' from file '/home/srcds/orangebox/garrysmod/lua/includes/modules/gm_sourcenet3_linux.dll':
        /home/srcds/orangebox/garrysmod/lua/includes/modules/gm_sourcenet3_linux.dll: undefined symbol: META_IGameEventManager2_name

My bad, I forgot to add the new obj files to the makefile. I'll fix it now.

Edited:

Fixed.

Possible to get a function for the CRC check?

What?

What?

[ clc_FileCRCCheck ] = { -- 14 (Untested)
			DefaultCopy = function( netchan, read, write )
				write:WriteUBitLong( clc_FileCRCCheck, 6 )
				
				local unk1 = read:ReadOneBit()
				write:WriteOneBit( unk1 )
				
				local gamepath = read:ReadUBitLong( 2 )
				write:WriteUBitLong( gamepath, 2 )
				
				local unk3

				write:WriteUBitLong( clc_FileCRCCheck, 6 )
				
				local unk1 = read:ReadOneBit()
				write:WriteOneBit( unk1 )
				
				local gamepath = read:ReadUBitLong( 2 )
				write:WriteUBitLong( gamepath, 2 )
				
				local unk3

				if ( gamepath == 0 ) then
					unk3 = read:ReadString() -- 10h
					write:WriteString( unk3 )
				end
				
				local unk4 = read:ReadUBitLong( 3 )
				write:WriteUBitLong( unk4, 3 )
				
				local filename = read:ReadString()
				write:WriteString( filename )
				
				local unk6 = read:ReadUBitLong( 32 )
				write:WriteUBitLong( unk6, 32 )
	
				debugprint( "FileCRCCheck", unk1, gamepath, unk3, unk4, filename, unk6 )

Possible to use this netmessage?

I'll look into it.

Edited:

That base code is really wrong (it writes the type twice), not sure how that happened.

Edited:

Fixed. I'm fairly sure the message is only used for sv_pure servers, so I'll have to find out how the server requests files to be checked.

This video should just about sum my thoughts up:

There is an example to remove client ip's from being sent to other clients in game events.

This module is amazing.

For some reason, whenever I try to create a game (Single or Multiplayer) I'm disconnected...
Here what is returned in console:

Do you have the latest version installed?

Edited:

Including the base code.

Edited:

I can't recreate it on my server.

Yep, gm_sourcenet3 r6b

I put all the example files in lua/autorun
but even with only basic files it still happens

It seems to be a listen server problem - I'll see what I can do about it.

[Kill coDer]

With respect to the VoiceData example, is it possible to grab the data on the server, send it with sockets in binary mode to another server then send it to all clients?

The issue I'm having is that I don't know how to get the server to send the mic chat to the clients on the other end. Will I have to create fake player objects? Or is it possible to stream the VoiceData with gm_bass?
