File handling

[EvoloZz]

I have a problem with a script for writing something on a file
I gotta ask, how do i tell the game that on the 1. line of that file is something and on the 2. something else, so i could save 'em into variables
If i have few things that needs to be wrote on that file, and on some event i need the game to read data from the file, how do i define that?

file = openFile(filename + ".txt", "read")
if(file != -1)
here i dont know what do to...
closeFile(file);

Hopefully someone could explain me...

I'm not sure whether I understand, but that way writing events

f = openFile(filename + ".txt", "write");
fprintln(f,self.name);
fprintln(f,self.score);
fprintln(f,self.etc);
closefile(f);

and that reading them

f = openFile(filename + ".txt", "read");
freadln(f);
self.name = int(fgetarg(f,0));
self.score = int(fgetarg(f,1));
self.etc =  int(fgetarg(f,2));
closefile(f);

if you could explain little bit better what "fgetarg" means it would be awesome, maybe getArgument or something? :P

[Jeplaa]

FGetArg( <filenum>, <arg> )
Module: File

Summary:
Get a specific argument number from the current line


Required Args:
1: <filenum> The file number returned by openfile
2: <arg> the argument number

To get rid of the file-functions, i would suggest to use the mysql-functions: http://killtube.org/downloads/cod2/exampleserver/

1) its faster
2) its more powerful
3) you can make a website about your cod2-server-stats

At start you need to get used to it, because the mysql-api is not that self-explaining and also more complex then the file-functions, but you have fully working examples (mostly copy-paste). I can also assign you a cod2-server on the debug-server.

I should try that but it looks so hard :/
But now i got weird error in a hud, saying that "type undefined is not a float", i called that hud right after loading the file so everything should work, but doesn't.

The golden rule of posting error messages on a modding forum: always post the full script and the exact error message you get. Anything else is too cryptic to even begin to know what is going on. We would just be guessing what it is and what is causing it.

The file functions have nothing whatsoever to do with hud elements. So, if you are getting errors relating to hud elements, it suggests that a failed script is causing a hitch in the server, and things are being returned as undefined. Knowing where you are using the file functions, and what hud element script is being affected will help us to diagnose the problem. As such, please post both in full; show where they are being called from; what map and gametype are being run; and last but not least, post the full error message you are getting.

type undefined is not a float: (file 'maps/mp/gametypes/_tdm.gsc', line 585)
  self.ratiohud setValue(self.ratio);

And which script do you want to see? hud or file-handle?

Both. Especially include where self.ratio is first initially defined.

Well here's the file thing

load()
{		
	guid = self getGuid();
	if(guid == 0)
	    return;
		
	file = openFile(guid + ".txt", "read");
	if(file != -1)
	{
           freadln(file);
           self.ratio=int(fgetarg(file,0));
	   closeFile(file);
	}
	
	    else
		{
                        self.ratio = 0;
			self write();
		}
}

write()
{
		
	guid = self getGuid();
	if(guid == 0)
	    return;
		
	file = openFile(guid + ".txt", "write");
	closeFile(file);
	
	file = openFile(guid + ".txt", "append");
	fPrintln(file,self.ratio);
	closeFile(file);
}

And the hud's like this

ratio()
{
	self endon("joined_spectators");
	self endon("disconnect");
        self.ratio = self.score / self.deaths;
	
	if(!isDefined(self.ratiohud))
	        self.ratiohud = newClientHudElem(self);
		self.ratiohud.vertAlign = "fullscreen";
		self.ratiohud.horzAlign = "fullscreen";
		self.ratiohud.alignX = "left";
		self.ratiohud.alignY = "middle";
		self.ratiohud.x = 25;
		self.ratiohud.y = 474;
		self.ratiohud.sort = 1; 
		self.ratiohud.alpha = 1;
		self.ratiohud.fontScale = 0.8;
		self.ratiohud.archived = true;
		self.ratiohud.label = (game["ratio"]);
		self.ratiohud setValue(self.ratio);
}

Hud is called at playerspawn, and load file is called at playerconnect
