COM_LoadPackFile

[Stealth Kill]

hi,

How can i use the function COM_LoadPackFile?
I made a Language menu

here is a small part

case 0:
COM_LoadPackFile ("PAKeng");
M_Menu_Main_f();
break;

case 1:
COM_LoadPackFile ("PAKdt");
M_Menu_Main_f();
break;

I removed my singleplayer.lmp from PAK0
and added it to PAKeng and PAKdt with different languages.

The Game starts with the language menu.
If I choose a language it should load the pak file and
go to main menu but
says singleplayer.lmp not found.

i think it doesn´t load the pak file but i don´t know why.

case 0:
COM_LoadPackFile ("PAKeng");
M_Menu_Main_f();
break;

case 1:
COM_LoadPackFile ("PAKdt");
M_Menu_Main_f();
break;

With the code above, you aren't specifying a directory or a file extension so it isn't finding the file.

Code: Select all

//
// add any pak files in the format pak0.pak pak1.pak, ...
//
	for (i=0 ; ; i++)
	{
		sprintf (pakfile, "%s/pak%i.pak", dir, i);
		pak = COM_LoadPackFile (pakfile);

The sprintf above is printing the directory into the variable with the extension.

case 0:
COM_LoadPackFile ("PAKeng");
M_Menu_Main_f();
break;

case 1:
COM_LoadPackFile ("PAKdt");
M_Menu_Main_f();
break;

ADD: Try these instead COM_LoadPackFile(va("%s/pakeng.pak", dir)) and COM_LoadPackFile(va("%s/pakdt.pak", dir));

Should work, at least as far as properly getting the pak file acknowledged as a place to look for files.

However, it looks like you are doing the above in the menu. The .lmp files are read rather early. Unless you are doing a command line parameter to specify the language, you'd need to get the menu elements reloaded.

hmmm i don´t know how to reload the menu

Sometime later today (several hours from now), I'll help you add it as a command line parameter (i.e. "yourquake -english") which will at least get this initially working for you for testing.

From that point forward, I'll look and see what surprises lie in reloading the menu elements (if any).

[Baker]

The command line parameter method of solving your problem:

In the example, there are 2 pak files named menu-dt.pak and menu-eng.pak.

If "-lang_dt" is added to the command line as such:

c:\quake\quake.exe -lang_dt

It will load the menu-dt.pak, otherwise it will by default use the menu-eng.pak.

void COM_AddGameDirectory (char *dir)
{
int i;
searchpath_t *search;
pack_t *pak;
char pakfile[MAX_OSPATH];

strcpy (com_gamedir, dir);

//
// add the directory to the search path
//
search = Hunk_Alloc (sizeof(searchpath_t));
strcpy (search->filename, dir);
search->next = com_searchpaths;
com_searchpaths = search;

//
// add any pak files in the format pak0.pak pak1.pak, ...
//
for (i=0 ; ; i++)
{
sprintf (pakfile, "%s/pak%i.pak", dir, i);
pak = COM_LoadPackFile (pakfile);
if (!pak)
break;
search = Hunk_Alloc (sizeof(searchpath_t));
search->pack = pak;
search->next = com_searchpaths;
com_searchpaths = search;
}

/* Begin modification */
if ((i = COM_CheckParm("-lang_dt"))) { // Check for command line param
// Load German Menu
sprintf (pakfile, "%s/menu-dt.pak", dir); // set filename
} else {
// None specified, load English
sprintf (pakfile, "%s/menu-eng.pak", dir); // set filename
}

pak = COM_LoadPackFile (pakfile); // Try to load it
if (pak) { // If successfully loaded, add to end of search paths
search = Hunk_Alloc (sizeof(searchpath_t));
search->pack = pak;
search->next = com_searchpaths;
com_searchpaths = search;
}

/* End modification */


//
// add the contents of the parms.txt file to the end of the command line
//

}

I didn't test this out but it should work as-is.

It works thanks

is it possible with a cvar too?

i tried this

Code: Select all

/* Begin modification */ 
if (i = (language.value == 1)) { 
// Load German Menu 
sprintf (pakfile, "%s/german.pak", dir); // set filename 
} else { 
// None specified, load English 
sprintf (pakfile, "%s/english.pak", dir); // set filename 

if i write this language "1" to my config.cfg
it stilll loads the english.pak.

Not as easily in the way you want to do it. The pakfiles are read at startup. Then the graphics are loaded.

It would almost be easier to load both menus at startup and have both sets of menus available. Then you could use a cvar.
