Sending events from sessions to uplink

[Jon100]

I'm currently building a controller script to run on the uplink that loads up game sessions as needed. I can get the controller to send events to its local sessions, but not the other way around.

Code: Select all

function main() 
{
	LavishScript:RegisterEvent[My_Event]
	Event[My_Event]:AttachAtom[MyEventExecuted]

	while (1) 
		waitframe 
} 

atom(script) MyEventExecuted(string mydata)
{
	echo "Event detected! ${mydata}"
}

The command

Code: Select all

Relay is1 -event My_Event "some data here"

works from uplink to session.

But when I try sent events from the sessions to the uplink....

Code: Select all

uplink -event My_Event "some data here"     is invalid
relay uplink -event My_Event "some data here"     does nothing.
relay all -event My_Event "some data here"    does nothing

Am I missing the right command or is this just not possible?

To relay to the uplink with the relay command, you must refer to the uplink by its given name, which defaults to your computer name.

You can alternatively execute the event as a command:
uplink Event[My_Event]:Execute["some data here"]

The -event switch is a convenience to reduce the amount of escaping you need to do in certain circumstances, and is not available on the uplink command

Fantastic!

By the way, is there a way to get your computer's name in LS?

Do a "Uplink RemoteUplink -list"

Hi Joe.

No, I mean a scripted way of getting the name. I currently have to create a servername.xml file on each of my computers containing the name of the current server so that my scripts know the server's name.

I can manually work out the name of my computers easily enough by looking at the big sicky label on the front case with their names printed on

Is there something like ${System.SystemName} that I could use instead?

Ah.. sorry. Sounds like a feature request

Or, you could write a quick extension that adds a SystemName command that returns the Windows local hostname. Use ISXDK and MKISX.exe, modify the resulting project.

After you add your command

Code: Select all

pISInterface->AddCommand("Sysname",Sysname,true,false);) 

and its return

Code: Select all

int __cdecl Sysname(int argc, char *argv[])
{
	printf("szHostName");
	return 0;
}

Something along the lines of..

Code: Select all

#include <winsock2.h>
WSADATA WSAData;

if&#40;&#58;&#58;WSAStartup&#40;MAKEWORD&#40;1, 0&#41;, &WSAData&#41; == FALSE&#41;

// Get local host name
char szHostName[128] = "";

-j

[eqjoe]

Ok.. that would never work. You dont want szHostName in quotes and you would have to add error handling after checking WSAStartup, but you get the idea...

it would be much easier to use System:APICall to call GetComputerName, but you can grab the name of the uplink via lavishscript.

Copied from DefaultUplinkUI.XML:

Code: Select all

${SettingXML[InnerSpace.XML].Set[Remote].GetString[Name].Escape}

Networking dudes like me use WinSock


Thanks Lax.

Clueless guys like me faint at winsocks API calls. Thanks guys
