All pointer<->integer conversion truncation warnings I'm aware of are now enabled for MSVC, to hopefully finally get that tool code 64bit-clean. I had to adjust the idCVar code for this - it should've been safe enough (highly unlikely that a valid pointer is exactly 0xFFFFFFFF on 64bit), but triggered those warnings - now it should behave the same as before but the warnings (which are now errors) are silenced.

Console Variables (CVars) are used to hold scalar or string variables
|
|
that can be changed or displayed at the console as well as accessed
|
|
directly in code.
|
|
|
|
CVars are mostly used to hold settings that can be changed from the
|
|
console or saved to and loaded from configuration files. CVars are also
|
|
occasionally used to communicate information between different modules
|
|
of the program.
|
|
|
|
CVars are restricted from having the same names as console commands to
|
|
keep the console interface from being ambiguous.
|
|
|
|
CVars can be accessed from the console in three ways:
|
|
cvarName prints the current value
|
|
cvarName X sets the value to X if the variable exists
|
|
set cvarName X as above, but creates the CVar if not present
|
|
|
|
CVars may be declared in the global namespace, in classes and in functions.
|
|
However declarations in classes and functions should always be static to
|
|
save space and time. Making CVars static does not change their
|
|
functionality due to their global nature.
|
|
|
|
CVars should be contructed only through one of the constructors with name,
|
|
value, flags and description. The name, value and description parameters
|
|
to the constructor have to be static strings, do not use va() or the like
|
|
functions returning a string.
|
|
|
|
CVars may be declared multiple times using the same name string. However,
|
|
they will all reference the same value and changing the value of one CVar
|
|
changes the value of all CVars with the same name.
|
|
|
|
CVars should always be declared with the correct type flag: CVAR_BOOL,
|
|
CVAR_INTEGER or CVAR_FLOAT. If no such flag is specified the CVar
|
|
defaults to type string. If the CVAR_BOOL flag is used there is no need
|
|
to specify an argument auto-completion function because the CVar gets
|
|
one assigned automatically.
|
|
|
|
CVars are automatically range checked based on their type and any min/max
|
|
or valid string set specified in the constructor.
|
|
|
|
CVars are always considered cheats except when CVAR_NOCHEAT, CVAR_INIT,
|
|
CVAR_ROM, CVAR_ARCHIVE, CVAR_USERINFO, CVAR_SERVERINFO, CVAR_NETWORKSYNC
|
|
is set.
