Adding a
Console Variable
I was putting a few new cvars into my code
recently, and had to go and look at a tut to see how it was done. That tut
wasn't on CVARS so I decided to put one together, partialy to make my own life
easier when i wanted to do it again.
This is a fairly easy one. No new files. It does
require a few changes to a few files though. The cvar I will be adding will be
called teamplay Simply chage it to whatever you want your cvar to be
The first file anything will be added to is
g_local.h Big surprise isn't it?.
Find the line which reads
extern cvar_t *maxclients;
And just under it put
extern cvar_t *teamplay;
extern means it isn't defined here but that it
exists and can be used. As this is in g_local.h it can be used anywhere in the
source.
Next open up g_main.c and find the line that reads
cvar_t *sv_cheats;
just under it insert
cvar_t *teamplay;
Thats it defined. now we need to initilize it.
open g_save.c and find the line
bob_roll = gi.cvar ("bob_roll", "0.002", 0);
And yet again insert this line under it
teamplay = gi.cvar ("teamplay", "1",CVAR_SERVERINFO|CVAR_LATCH);
CVAR_SERVERINFO|CVAR_LATCH makes it server
information and makes it latch (stick around until the server restarts). I'm
not going to list the flags you can use. the number is the default value of the
cvar
Thats the basics of adding a cvar., heres how to
use it
check the value of coopexit->value in code
where you want to check the cvar. easy don't you think?
