[Opde-devel] Inheritance Service

[Filip V. <f.v...@ce...>]

Hello everybody,

as I promised, I started working on the InheritService. A working
skeleton is present in CVS, currently only listening to MetaProperty
relation messages, and updating it's internal source/destination 
inheritance maps. It does broadcasts too itself, which will be used by
caching inheritors, so those will be able to rebuild the internal map of
effective object id's.

Now I would like to finish this soon, hopefully this week (But I know
that this is little bit too optimistic). After this, All the
modifications to the property service will be made. I do not know yet if
even the inherited property should be a source to the property change
broadcasts. It seems that Dark handles this in a sorta fuzzy way,
because some key properties are not concrete inherited - only archetype
inherited. That means that the property itself (not an inherited one) is
used on concrete objects (copied upon instantination of the archetype),
so maybe broadcasting inherited property asignments will not be needed.
If it will, the change will be rather simple really. I'd like to split
the properties to active/passive (only active would broadcast), but this
probably won't fit...

Object service will be next. That one will handle: createFromArchetype,
create, nameToID, idToName, object death, pre-death, object creation
messages, some clever ID mapping for objects, etc.

I really wish to finish this soon, because the main work on the engine
will then be possible - all those fancy core features, such as tweq's,
frobbing, particle systems, etc.

Please report any compilation problems to me if you try to build opde
now, it may be inconsistent (mainly as I have some pending modifications
in the DarkSceneManager, and won't commit those till I have a working
stencil/lightmap global shadows - and that will take some time to do).

As a side note: I migrated to Code::Blocks, as SVN version of it finally
works like a charm, and CMake CVS version can generate project files for
it. If somebody want's cmake cvs ebuild for gentoo, I can send it. The
C::B really is a nice dev. platform, finally the code completion works
as it should (with one exception - completion over the -> operator,
which is used in shared_ptr template).
