\brief .fgd entity description format
FGD loading code by Dominic Clifton - Hydra (Hydra@Hydras-World.com)
Overview
========
This module loads .fgd files, fgd files are split into classes:
base classes
point classes (aka fixed size entities)
solid classes (aka brush entity)
This program first scans each file, building up a list structures
in memory that contain the information for all the classes found
in the file.
Then the program looks at each of the non-base classes in the list
and build the eclass_t structure from each one.
Classes can request information in other classes.
Solid/Base and Point/Base classes can have the same names as other
classes but there can be only one of each solid/point/base class with
the same name,
e.g.:
this is NOT allowed:
@solidclass = "a"
@solidclass = "a"
this is NOT allowed:
@pointclass = "a"
@solidclass = "a"
this IS allowed:
@solidclass = "a"
@baseclass = "a"
Version History
===============
v0.1 - 13/March/2002
- Initial version.
v0.2 - 16/March/2002
- sets e->skinpath when it finds an iconsprite(<filename>) token.
v0.3 - 21/March/2002
- Core now supports > 8 spawnflags, changes reflected here too.
- FIXED: mins/maxs were backwards when only w,h,d were in the FGD
(as opposed to the actual mins/maxs being in the .def file)
- Made sure all PointClass entities were fixed size entities
and gave them a default bounding box size if a size() setting
was not in the FGD file.
- Removed the string check for classes requesting another class
with the same name, adjusted Find_Class() so that it can search
for baseclasses only, this fixes the problem with PointClass "light"
requesting the BaseClass "light".
v0.4 - 25/March/2002
- bleh, It turns out that non-baseclasses can request non-baseclasses
so now I've changed Find_Class() so that it can ignore a specific class
(i.e. the one that's asking for others, so that classes can't request
themselves but they can request other classes of any kind with the
same name).
- made all spawnflag comments appear in one place, rather than being scattered
all over the comments if a requested class also had some spawnflags
v0.5 - 6/April/2002
- not using skinpath for sprites anymore, apprently we can code a model
module to display sprites and model files.
- model() tags are now supported.
ToDo
====
* add support for setting the eclass_t's modelpath.
(not useful for CS, but very useful for HL).
* need to implement usage for e->skinpath in the core.
* cleanup some areas now that GetTokenExtra() is available
(some parts were written prior to it's creation).
* Import the comments between each BaseClass's main [ ] set.
(unfortunatly they're // cstyle comments, which GetToken skips over)
But still ignore comments OUTSIDE the main [ ] set.
