CoD4 - openfile

[BlancO]

The problem is I can't open file.

Console_mp.log

		Error: 
******* script compile error *******
Error: return value of developer command can not be accessed if not in a /# ... #/ comment: (file 'blanco/_start.gsc', line 25)
 f = openfile("file.txt", "write");
     *
************************************ 
	

Script

		f = openfile("file.txt", "write");
fprintln(f, "Save it to file.");
closefile(f); 
	

[IzNoGoD]

In cod4 its only avail in developer mode. Not advised for running servers with developer enabled.

Use kung's cod4 extension for a full mysql interface.

[Peterlankton]

Actually I've never met a CoD4 scripter who used openfile() etc. They used getStat() and setStat() if they wanted to save any data.
Either do what IzNoGod said or try it my way.

[BlancO]

Should I use it like:

		self setStat("kills", 0);

kills = self getStat("kills"); 
	

[Peterlankton]

Yup, that actually should work.

Though I would recommend using it like this.

		self maps\mp\gametypes\_persistence::statSet("kills", 0);
kills = self maps\mp\gametypes\_persistence::statGet("kills"); 
	

Also you have the statAdd() function.
For example:

		self maps\mp\gametypes\_persistence::statAdd("kills", 1); 
	

This would add 1 killpoint to the existing ones.
It's a bit shorter than

		 curValue = self maps\mp\gametypes\_persistence::statGet("kills");
self maps\mp\gametypes\_persistence::statSet("kills", curValue+1);

The very big problem about stats is that they are not saved on the server, but on the client's PC. So it's kind of easy to hack and fake stats. So I'd rather recommend you mysql to be honest.

No, setStat() and getStat() only work with integers - not strings. If you want to use a string, do what IW themselves did and invent a method which allows you to keep a list of your stats against a string reference. Check out COD4 _persistence.gsc and the accompanying playerStatsTable.csv. These are the 2 primary functions:

/*
=============
statGet

Returns the value of the named stat
=============
*/
statGet( dataName )
{
if ( !level.rankedMatch )
		return 0;
	
	return self getStat( int(tableLookup( "mp/playerStatsTable.csv", 1, dataName, 0 )) );
}

/*
=============
setStat

Sets the value of the named stat
=============
*/
statSet( dataName, value )
{
	if ( !level.rankedMatch )
		return;
	
	self setStat( int(tableLookup( "mp/playerStatsTable.csv", 1, dataName, 0 )), value );	
}

An example of how they are used:

 self satSet( "kills", 10 );

That would go to the satSet() function, and it would lookup the string "kills" in playerStatsTable.csv and find the stat number against the string reference.

Yup, that actually should work.

Though I would recommend using it like this.

		self maps\mp\gametypes\_persistence::statSet("kills", 0);
kills = self maps\mp\gametypes\_persistence::statGet("kills"); 
	

Also you have the statAdd() function.
For example:

		self maps\mp\gametypes\_persistence::statAdd("kills", 1); 
	

This would add 1 killpoint to the existing ones.
It's a bit shorter than

		 curValue = self maps\mp\gametypes\_persistence::statGet("kills");
self maps\mp\gametypes\_persistence::statSet("kills", curValue+1);

No, it wont work - getStat() and setStat() only works with numbers (integers).

As pointed out already, the File functions only works in developer mode. However, if you want to READ data, use COD4 tableLookUp() function. I did this for a rank system in COD4 1.0 - 1.4, before IW enabled the getStat() and setStat() for mods. Before that, ranks could not be saved (the "write" File function only worked in developer mode), but we could at least read data.

Following on from above post:

If you want to create your own stat-finding function similar to IW's, the following is a list of the free stats available. Just put them in a .CSV file and put a string reference of your choice in line 2:

Call the table customStatsTable.csv.

Now, the custom functions to find the stat by string reference:

statGetCustom( dataName ) {
	return self getStat( int(tableLookup( "mp/customStatsTable.csv", 1, dataName, 0 )) );
}

statSetCustom( dataName, value ) {
	self setStat( int(tableLookup( "mp/customStatsTable.csv", 1, dataName, 0 )), value );	
}

Well, thanks a lot but I have few questions.

Are these stats server-side or client-side? (I mean can player edit his stats) (What is the path to it)


Is it correct?

customStatsTable.csv

		3150,kills
3151,score
3152,connects
3153,spawns 
	

.gsc script

		getData( dataName )
{
    return self getStat( int(tableLookup( "mp/customStatsTable.csv", 1, dataName, 0 )) );
}

setData( dataName, value )
{
    self setStat( int(tableLookup( "mp/customStatsTable.csv", 1, dataName, 0 )), value );    
}

addData( dataName, value )
{
    newValue = getData( dataName ) + value;
    self setStat( int(tableLookup( "mp/customStatsTable.csv", 1, dataName, 0 )), newValue );    
} 
	

mod.csv

		stringtable,mp/customStatsTable.csv
