This is the last time I'll ask this question on the list. I promise. :)
I'm going to try to explain in depth so maybe someone will have a sudden
idea that might work.
Overview -
I want to be able to access server CVAR's on the client. By server, I
mean a CVAR that can only be set on the server (such as sv_gravity or in
this case a new one I've made: mp_aquashotgun). I really don't care HOW I
get to access it on the client, just as long as I can do it.
Scenario 1 -
In this best case scenario, I can somehow tell Half-Life to propagate
the CVAR to the client by its own internal networking. For example, when I
define the CVAR I could let Half-Life know it should be like
FCVAR_SENDTOCLIENT or some such thing. In this case, I could somehow access
the CVAR with a CVARGetFloat kind of function on both the server and the
client.
Because the CVAR I am dealing with must be used by a weapon, it has to
be accessible in a weapon file shared between the server and the client. My
main problem here is the CVAR_GET_FLOAT function used on the server is not
accesible by the client. The equivalent client-side function
(gEngfuncs.pfnGetCvarFloat) can't be used in a weapons file because the
weapons file is shared between the server and the client. If I try to use it
hear, gEngfuncs is undefined. If I include the correct headers, they
conflict with other already included headers (ie. util.h). If I try to add
just the definition of gEngfuncs, the whole file just becomes one big
unreadable mess where nothing works.
Scenario 2 -
Somehow I could detect when the CVAR changes. When it does, I send a
custom message (through MESSAGE_BEGIN, etc) to the client to update a
variable there. I can now access this variable on the client. Question: how
do I access this variable? Can I just declare it as extern or something? I'm
really not sure how this whole 'shared' thing works.
Conclusion -
Those are the only two options I can think of. The whole problem stems
from the client-side weapons and the shared weapons files. Before, when the
weapons were server-side only, there was no problem. But if I don't
propagate the CVAR to the client (mp_aquashotgun), it might show the
animation for firing under water when really the server won't allow it or
vice versa.
Anyone! Valve! There MUST be a way to somehow go about doing this. I'm
missing it, but I hope you can point it out! It's been a problem for me for
over a month now, and I still haven't found a solution. I will be very
thankful to the kind soul who can solve this problem.
