Getting message details

Geesu · **Author**

Is it possible to loop through like numbers 1-100 to try to find valid message IDs, then to see what the names of the messages are as well as how many arguments each takes? (yes I know I'm probably dreaming)

Anyone know?

Yes and No.

You _can_ look though message indexes and retrieve the 'text' name of them. However if you try and get an index that doesn't exist (out of range) the server crashes.

What function lets me loop through them?

Code:

bf_write* VFUNC myUserMessageBegin(IVEngineServer *pEngine, IRecipientFilter *filter, int msg_type)
{
	LOG("myUserMessageBegin([%x] [0x%X] [%d])", pEngine, filter, msg_type); 
	bf_write *pTemp = engine_UserMessageBegin(pEngine, filter, msg_type);
	
	if (INTERFACES_(pUserMessages))
	{
		char *szName = NULL;
		
		szName = INTERFACES_(pUserMessages)->GetUserMessageName(msg_type);
		
		LOG("[%d] = [%s]", msg_type, (szName) ? szName : "NULL");
	}
	else
	{
		LOG("0x%x of pUserMessages", INTERFACES_(pUserMessages));
	}
	return pTemp;
}

//CUserMessages *pUserMessages;

This is the code I use when messages are sent. Or basically: char *CUserMessages::GetUserMessageName(int msg_type);

Only problem is, you don't have direct access to usermessages, so you have to use something like Lance's sigscanner, or maybe even GetProcAddress, to derive the address from the server.dll.

Ouch, reading you post Manip I realized I responded on thegizmo's post and not the original... my code was about displaying the usermessages sent and the arguments...

Me, I use the "built" in:

Code:

UserMessageBegin( filter, "VGUIMenu" )

So I don't need to know the number...

My code kicks all of your code's asses:

Code:

short CCoreNatives::UserMessageIndex(const char *messageName)
{
	char name[128] = ""; int sizereturn = 0; bool boolrtn = false;
	// TODO: Find out how to get total number of user messages on a server DLL
	// HACK: If the total number of user messages < 22 it will crash the mod(!)  
	for(int x=1; x<22; x++)
	{
		boolrtn =  m_GameDLL->GetUserMessageInfo(x, name, 128, sizereturn);  
		if(name && strcmp(messageName, name) == 0) 
			return x; 	
	}
	return -1; 
}
