File handling

[Tally]

Ok, I found out what the problem is - once a file has been created using the "write" function, it wont update. So, you are fine entering data into file the very first time. After that, it simply doesn't update any more. So, you have to use the "append" function, and read the data back from that basis.

Here is what I have:

onPlayerConnect()
{
	// initialize the player kills flag
	if( getPlayerKills() )
		self.pers["kills"] = self.kills;
	else
		self.pers["kills"] = 0;
}

onPlayerKilled()
{
	attacker.pers["score"]++;
	attacker.score = attacker.pers["score"];
	// update the player kills flag along with player score
	attacker.pers["kills"]++;
	// save the new player kills value
	attacker thread saveKills();
}

saveKills()
{
	filename = self.name + ".txt";
	filehandle = openfile( filename, "append" );
	
	if( filehandle != -1 )
	{
		value = "";
		if( value != "" ) value += " ";
		value += self.pers["kills"];
		
		fprintln( filehandle, value );
		closefile( filehandle );
	}
}

getPlayerKills()
{
	filename = self.name + ".txt";
	file = OpenFile( filename, "read" );
	
	if( file == -1 )
		return( false );
	
	for( ;; )
	{
		elems = freadln( file );
		
		if( elems == -1 )
			break;
			
		if( elems == 0 )
			continue;
	
		line = "";
		for( pos = 0; pos < elems; pos++ )
		{
			line = line + fgetarg( file, pos );
			if( pos < elems - 1 )
				line = line + ",";
		}
			
		array = strtok( line, "," );
		self.kills = array.size;
	}
	
	CloseFile( file );
	
	return( true );
}

I was using a simple player name for the data file name, but obviously you simply replace that with a more robust player GUID name (although I would shorten the file name to the last 8 digits).

I didn't do anything with a HUD element showing these values. I will take it that aspect of the thing can be easily created yourself.
