Title: Noob question --> setting a client var
Post by: SPK on November 13, 2010, 03:41:22 pm

Well I'm just learning to code basic things in QVMs, the only thing is that I dont know C, just the basic programming syntax...
I want to set a client var, and be able to change it on console by '/var value'

BTW I have this:

In g_local.h:    
---------------------------------------

typedef struct
{
...
lang_t           lang;  
...
}

---------------------------------------



In bg_public.h:
--------------------------------------

typedef enum
{
  LANG_ESP,
  LANG_ENG,
  LANG_DEF
} lang_t;

--------------------------------------


In g_client.c:
--------------------------------------

s = Info_ValueForKey( userinfo, "cl_lang" );

  if( !Q_stricmp( s, "esp" )  )
    client->pers.lang =   LANG_ESP;
  else if( !Q_stricmp( s, "eng" )  )
   client->pers.lang = LANG_ENG;
  else
   client->pers.lang = LANG_DEF;

-------------------------------------


Whats the noob thing I'm missing?
Thanks for reading : /

EDIT: Additional obvious info:
I can compile the qvm and check that the server loads it correctly, so dont think about this

You're looking in the wrong place, try searching the files for the name of an already existing cvar like "cg_teamOverlayMaxPlayers" perhaps, or "cl_useMumble". It isn't that hard to add, don't try to write much code beyond variable declarations and the definition of the cvar (which gives it an initial value). In total it will be around 3 lines of code in a few different files.

My apologies, cg_* variables aren't in the file I'm thinking of. Here is a section of the diff from my build queue slowdown mod (src/game/g_main.c). Playing around with this should give you most of what you want.

The client needs to have the cvar with CVAR_USERINFO, either from a custom cgame or the user setting it by setu cl_lang eng

Thank you guys = )  If I get anything I'll post here

EDIT: David, you mean I cannot do anything just with the qvm code? : /

You can, but the user will need to set it with setu instead of set.
