Unchained, Ultimate, Ultra, Up Yours, Underworld, Underground, Unified, Unity, etc. You know the drill. This takes care of the "standalone" problem with the wrong name, and the recent snafu with multiple developers working on the same files simultaneously...expect me (and probably others) to start locking dirs when updates are taking place. And yes, this update is really as large as it looks. Software only at the moment, but I will have the makefile updated to build the GL builds as well.

/*
|
|
|
|
cvar_t variables are used to hold scalar or string variables that can be changed or displayed at the console or prog code as well as accessed directly
|
|
in C code.
|
|
|
|
it is sufficient to initialize a cvar_t with just the first two fields, or
|
|
you can add a ,true flag for variables that you want saved to the configuration
|
|
file when the game is quit:
|
|
|
|
cvar_t r_draworder = {"r_draworder","1"};
|
|
cvar_t scr_screensize = {"screensize","1",true};
|
|
|
|
Cvars must be registered before use, or they will have a 0 value instead of the float interpretation of the string. Generally, all cvar_t declarations should be registered in the apropriate init function before any console commands are executed:
|
|
Cvar_RegisterVariable (&host_framerate);
|
|
|
|
|
|
C code usually just references a cvar in place:
|
|
if ( r_draworder.value )
|
|
|
|
It could optionally ask for the value to be looked up for a string name:
|
|
if (Cvar_VariableValue ("r_draworder"))
|
|
|
|
Interpreted prog code can access cvars with the cvar(name) or
|
|
cvar_set (name, value) internal functions:
|
|
teamplay = cvar("teamplay");
|
|
cvar_set ("registered", "1");
|
|
|
|
The user can access cvars from the console in two ways:
|
|
r_draworder prints the current value
|
|
r_draworder 0 sets the current value to 0
|
|
Cvars are restricted from having the same names as commands to keep this
|
|
interface from being ambiguous.
