Don't include the lazy precompiled.h everywhere, only what's required for the compilation unit. platform.h needs to be included instead to provide all essential defines and types. All includes use the relative path to the neo or the game specific root. Move all idlib related includes from idlib/Lib.h to precompiled.h. precompiled.h still exists for the MFC stuff in tools/. Add some missing header guards.

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.
