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.

Declaration Manager
|
|
|
|
All "small text" data types, like materials, sound shaders, fx files,
|
|
entity defs, etc. are managed uniformly, allowing reloading, purging,
|
|
listing, printing, etc. All "large text" data types that never have more
|
|
than one declaration in a given file, like maps, models, AAS files, etc.
|
|
are not handled here.
|
|
|
|
A decl will never, ever go away once it is created. The manager is
|
|
garranteed to always return the same decl pointer for a decl type/name
|
|
combination. The index of a decl in the per type list also stays the
|
|
same throughout the lifetime of the engine. Although the pointer to
|
|
a decl always stays the same, one should never maintain pointers to
|
|
data inside decls. The data stored in a decl is not garranteed to stay
|
|
the same for more than one engine frame.
|
|
|
|
The decl indexes of explicitely defined decls are garrenteed to be
|
|
consistent based on the parsed decl files. However, the indexes of
|
|
implicit decls may be different based on the order in which levels
|
|
are loaded.
|
|
|
|
The decl namespaces are separate for each type. Comments for decls go
|
|
above the text definition to keep them associated with the proper decl.
|
|
|
|
During decl parsing, errors should never be issued, only warnings
|
|
followed by a call to MakeDefault().
