Assuming you're using GDK it could be the bug that overwrites some memory when an error occurs (anything that would trigger an error in DBPro). Why TGC haven't fixed this amazingly serious bug after all this time, I don't know.

I'm curious to know what the differences are between MikeNet and Multisync 1.4.1..... Multisync uses TCP. Does MikeNet use UDP? Are there any other differences? I posted a similar question on the MikeNet thread.

Lets start by saying: "Awesome plugin!"

Lets follow by: "I got it installed on GDK and i tought if there are any example for DarkGDK? This might have bene asked before. Anyway, if there are can u point me to any?"

Hello everyone

I was wondering, how to let someone connect to my PC (my pc is running the server app) through the internet? i only succeed getting this to work connecting from my pc to itself, or to a pc on my network, but not over the net, does this have anything to do with ports? what port should i use? and which IPs i should host/connect with?

go to [href]www.whatismyip.com[/href] and thats your IP adress... just give that to your client, but if you are behind a router, you are gonna have to make some port forwarding... which you can google

I've posted this information numerous times on these forums but unfortunately the search feature is practically useless for finding them. So, here we go again...

1. Host with your computer's LAN IP (you can obtain this from ipconfig).

2. In your router settings forward TCP port 3999 (or whatever you've changed the port to) to the computer (using the LAN IP again).

3. Have clients on the internet connect using your internet IP. Clients on the same LAN will have to use your LAN IP.

Hope it helps.

@bergice; If I recall correctly, that green arrow next to the breakpoint means it is the next statement to run, not the current one - which probably means your problem is somewhere prior to that.

Where is typeOfPeer delcared?

The yellow arrow is the next statement to run, and the green arrow represents a function that was on the stack at the time of the exception.

I'm thinking of using an old computer (nvidia geforce mx440) as a server, but when i ran the Example 1 server as a test, it came up with the standard crash dialog saying "modname: multisync.dll". I have dx 9.0c installed, but is there anything else I would need?

Quote: "I also found out the connection will time out and disconnect the client after 30 seconds "

Thanks for this! Otherwise I might have been throwing a tantrum right now. Actually, something i'm doing now is stopping it from disconnecting, even without sending messages. Perhaps calling net connected(), or similar.

This is much faster than the standard DBP multiplayer commands for connecting. Also, I am able to tell the host to stop hosting, then restart, which I couldn't manage with the standard commands (I may have missed something). This is what I will be using. Thanks for the dll.

Hey! I just download this plugin and works well.

But there is one thing what im missing from it.

I hosted a server, and my question is how can i list the available servers on the client side.
So when i join i dont want to type the server ip. I need a functions for it to list the servers.

And other question, is there a function to get my ip?

I've been trying to test this and I'm not getting anywhere. When I have a player join, he's now connection num1. Someone else joins and hes now connection num2. If connection num1 leaves, is the second guy still connection num2? Or is he bumped down to connection num1?

Hi,
Every time I attempt to use multisync while joining as a client the connection fails and the error report says "Timed Out". I know it's not just my code because even Agent's MMORPG in the WIP section uses your DLL and I still receive the "Timed Out" message when attempting to join.

Any suggestions?

Theres a really annoying bug that has given me tons of problems.
I can'ts "net put int" a UDT and/or DIM() variables. Everytime I want to put said variable type I have to set that variable to a local variable and then put that variable.

I'm having exactly the same problem.
Any ideas / workarounds would be nice (may it be that the library requires something from the DarkGDK library ie. for memblock support?)

Ah, seems mr Benjamin answered that over here.

Quick fix is to slap this in the main loop (of the server) to handle the message queue of the app:

(Where msg is declared as MSG pointer (from Windows.h)).

Is it possible for a server to open up a second connection as a client while it is still serving its own clients?

I have a client server game fully operational at the moment but I am looking to implement a copy protection system in which the client sends its cd-key to the server when it connects, and the server then connects to the authentication server to check if the key is valid before accepting the connection from its own client. In order to do this, I need my game server to continue serving its existing clients while it opens up a new connection as a client, to talk to the authentication server.

Can this be done?

I have done the same thing with my server. Just program your authentication program as a CLIENT and have the server wait for the authentication program to connect before letting any other clients connect. I've done this by simply rejecting all outside connections until a client connects with a certain IP.

You might consider doing it the way I did when using Multisync. I had the clients connect to the authentication server to both verify their key and give them the server list. If they have an invalid key you simply don't send them the server list. If there is no way to manually enter an IP in the client this works pretty well.

EDIT: Though what Qqite suggested is a pretty good idea too.

Thanks for the suggestions, guys. The problem with this idea though is that the authentication server will need to connect to every single game server out there. First of all, how will it know where they all are, and secondly how can it connect, as a client, to more than one server at the same time?

Does anyone know how to establish a connection past a router without port forwarding? I'm planning on making a matchmaking service that people connect to (static IP and such) and when they want to start a game, it let's one of the players become the server and everyone else connects to that player.

I got the matchmaking down, but once everyone is ready to connect to one of the players I don't know how to bypass the port forwarding issue.

This is possible because almost 99% of PC games has this feature; you can go online to find a list of games and then join them without having to gset up ports and such.

Clients don't require port forwarding, only the servers do.

I know that, but how are games like Halo 2 Vista and other "matchmaking" games able to give a random player the ability to server a game? Does the main server relay the data? That sounds very inefficient and slow...

It only does that if you call the connect function without returning a value.

Thanks dude! Multisync works really well.

One of the things that was confusing when I started though was that looking at the readme, none of the functions are listed with "()" at the end, and without "()" they work but can't return variables.

I got a crash when I tried to host when another host already existed (on the same machine). That's not something i expect users to do though so it's no big deal.

Multisync connects so much faster than the standard DBP multiplayer commands. (which seem broken when compiled in the latest DBP anyway!)

That's what I asked earlier, Ceto. Apparently the answer is that it was a planned feature for the future that never made it into final, so no this isn't possible.

I've worked with tempest in the past (a few years ago) and have since been working on a new multiplayer game. I want to use this game primarily for LAN connections and later across the internet. But I want to be able to call a list of local games much like tempest did. What do people suggest as the best/most secure/fastest/easiest way to do this? I've toyed with creating a list of local servers so that someone can check their ip against a list, then see the local ips under that main ip. This seems a bit excessive traffic wise to be updating an online list for LAN IPS.... but then again it's just my one idea. Any help or pointing in the right direction I would love.

And this is also my first post in a LOOOOOOOOOOONG time. So... hey TGC I'm back!

Just wanted to share my solution to my own problem, listed a few posts above this one.

I now run a master server on a static IP. When a game server is run, it first connects as a client to the master server, and tells it "Hi, I'm a game server, this is my IP". The master server sends an acknowledgement and then drops the connection. The game server then sets up fresh netcode as a server, and begins accepting connection from game clients. If the game server is exited normally, it drops all client connections, becomes a client and connects to the master server again, telling it "We're done here, I'm out". The master server receives this signal, removes that game server's IP from its list and drops the connection. Then the game server terminates.

When clients wish to connect to a game server, they first connect to the master server on the master IP and sends it "Hi, I'm a game client, this is my authentication key". The master server checks the key and validates it. If the validation check fails, the client is immediately disconnected. If the check passes, the master server sends the client a list of game server IP's. The client can then choose one, drop the connection to the master server and establish one to the selected game server.

The advantages of this system are that the master server can enforce authentication key validation, which will provide for suitable copy protection. Additionally, this system is a pretty common way of registering servers for clients to find, so your server will always be listed for all clients. Because every client will connect to the master server during its startup, the master server can send things like message of the day and development news to clients so they can be kept up to date.

There are two fairly major disadvantages to this system though. If the master server goes down, no client in the world will be able to play the game at all. This holds true for most commercial multiplayer games however, so this could still be acceptable provided I field a nice and stable master server. The other substantial disadvantage is that if a game server quits in any way other than normally (ie, crash or Alt-F4 rather than a typed QUIT command) then the master server will never be notified that this game server is offline.

I wanted to have the master server periodically ping all game servers that it's aware of to see if they are still alive and remove any game server that doesn't respond. There seems to be no way to do this, though. If I can find a way to accomplish this periodic check-alive ping while continuing to serve clients (or to have game servers periodically send a keep-alive ping to the master server while still serving their clients) then this will no longer be a problem.

Any ideas?

That's a good question. I gather things have to be client or server and not both. Perhaps there could be 2 programs running on the server. One host for accepting connection from users, and another client program that cycled through list of hosts and checks that it can connect to each. The two programs can talk to eachother by either the client connecting to the host, or via some shared file - it only need contain the list of host ips - if the checker fails to connect, it takes the entry off the list.
