Hi, i started using multisync today, but i am having a problem... I created server and client apps, and i am able to host a game in the server app, but cant connect to it with client on another computer. Maybe that is because i have a router, and i could have some ports blocked. Besides, there is no documentation about that in C++...
Client:

+ Code Snippet

#include "DarkGDK.h"
#include "multisync.h"

int result;
char ip[50] = "127.0.0.1";     //the same as in server
void DarkGDK ( void )
{
	dbSyncOff();
	dbAutoCamOff();
result = NetConnect(ip);
if(!result)
{
	dbText(0,0,"Couldnt connect to server");
	dbWaitKey();
	return;
}
	dbSyncOn   ( );
	dbSyncRate ( 60 );
	while ( LoopGDK ( ) )
	{
		dbText(0,10,"Connected");
		dbText(0,30,dbStr(NetGetPlayerAmount()));
		dbSync ( );
	}
	return;
}

Server:

+ Code Snippet

#include "DarkGDK.h"
#include "multisync.h"

int result;
char erro[512];
char ip[50] = "127.0.0.1";

void DarkGDK ( void )
{
	dbSyncOff();
	dbAutoCamOff();

result = NetHost_IP(2,ip);
if(!result)
{
	dbText(0,0,"Coudnt create server");
}
	dbSyncOn   ( );
	dbSyncRate ( 60 );
while ( LoopGDK ( ) )
	{
		dbText(0,10,"Server successfuly created !");
		dbText(0,30,dbStr(NetGetPlayerAmount()));
		dbSync ( );
	}
	return;
}

Btw, how does NetGetError() work ? It doesnt return a string or something...

See this thread for some information.

If you're using 127.0.0.1 then you can only connect a client on the same computer, as that address bypasses any networking card you have installed. Specifying 0.0.0.0 on the server and the servers's LAN IP on the client should work (assuming you want to connect from another computer on your LAN).

The server needs to regularly call NetPlayerJoined to check if players have joined, but more importantly it also allows players to join. The same applies for NetPlayerLeft.

Thanks, it works now, but the amount of players is always zero...
Server:

+ Code Snippet

#include "DarkGDK.h"
#include "multisync.h"

int result;
char erro[512];
char ip[50] = "127.0.0.1";

void DarkGDK ( void )
{
	dbSyncOff();
	dbAutoCamOff();

result = NetHost_IP(2,ip);
if(!result)
{
	dbText(0,0,"Coudnt create server");
}
	dbSyncOn   ( );
	dbSyncRate ( 60 );
while ( LoopGDK ( ) )
	{
                if(NetPlayerJoined()>0) dbText(100,0,"Player joined");
		dbText(0,10,"Server successfuly created !");
		dbText(0,30,dbStr(NetGetPlayerAmount()));
		dbSync ( );
	}
	return;
}

Also, if i see the ipadress of this computer on internet, can i use it as the server ip adress so other players can join it, somewhere else ?

In that snippet you're still using 127.0.0.1.

Not sure what you mean, could you rephrase that?

Yes, i was using 127, but tested to connect to server on the same computer...
For example, my IP address is 213.13.200.6 from (http://whatismyipaddress.com/) Can i use it as the ip of the server app, so other players can join the game online?

If you're asking if you can use it in NetHost_IP, the answer is no unless you are directly connected to the internet (without a router, which is rare these days). In order for users on the internet to connect you need to either use your computer's LAN IP, or 0.0.0.0 as it's easier. Users on the internet then connect using your internet IP.
