Try to clean up the frametime global. fix some quirks with r_dynamic -1 Added scr_fov_mode cvar to control whether the fov is defined relative to horizontal, vertical, or guessed. fix a few fteqcc bugs tab completion for the gamedir command. fix the savegame_legacy command. it wasn't entirely compatible. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5254 fc73d0e0-1445-4013-8a0c-d673dee63da5

/*

|
|
|
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.
