Re: [hlcoders] Server Plug-in Loading Order
Michael:
I'm doing that exact same thing right now, for a module for a plugin
manager that shall remain nameless :P
Your plugin is loaded before any ents are created, obviously, but
after all the factories are initialized and the class maps prettied up
and whatnot - a very good time for loading. Hooking CreateEdict is
nice, but it won't tell you what type of entity is being created.
So I went on to hooking EntityFactoryDictionary, which I've become
quite fond of :D A windows only way of getting the EFD ptr is in my
sigscanner thread on the forums of that place (nasty, I know, but hey
it works - haven't had to update it since I made it) - the linux way
is a ton easier. Using my vfunc hook thing again from those forums
heres a way to hook the creation of any ent, and do with it what you
will (too lazy to make my vtbl hook work on lin atm, but I'll be
forced to soon - again it's a ton easier)
class CEntityFactoryDictionary : public IEntityFactoryDictionary {
public:
CEntityFactoryDictionary();
void InstallFactory( IEntityFactory *pFactory, const char *pClassName );
IServerNetworkable *Create( const char *pClassName );
void Destroy( const char *pClassName, IServerNetworkable *pNetworkable
);
public:
IEntityFactory *FindFactory( const char *pClassName );
CUtlDict IEntityFactory *, unsigned short m_Factories;
};
CEntityFactoryDictionary* pEntityFactoryDictionary = NULL;
CSigScanner SigEntityFactoryDictionary(SigEntityFactoryDictionary,
SIGRANGESERVERDLL, pEntityFactoryDictionary,
xxxxxxxxxxx,
\x8A\x0D\x58\x16\x5A\x22\xB0\x01\x84\xC8\x75\x21\x8A\xD1\x0A\xD0\xB9\x08\x16\x5A\x22\x88\x15\x58\x16\x5A\x22\xE8\x60\x00\x00\x00\x68\x30\xD9\x3A\x22\xE8\x2F\x99\x01\x00\x83\xC4\x04\xB8\x08\x16\x5A\x22\xC3,
17, false, 2); //lol
DEFVFUNC(EntityFactoryDictionary_Create, CBaseEntity*,
(CEntityFactoryDictionary*, const char* lpcClassName));
CBaseEntity* VFUNC myEFD_Create(CEntityFactoryDictionary* pEFD, const
char* lpcClassName){
CBaseEntity* pEntity = EntityFactoryDictionary_Create(pEFD,
lpcClassName);
LOG(Made ent: [%s] %x, lpcClassName, pEntity);
return pEntity;
}
init
HOOKVFUNC(pEntityFactoryDictionary, 1,
EntityFactoryDictionary_Create, myEFD_Create);
Regarding modifying those entities, hook their vtbls - you can do
anything you want ot them. If you want a single instance only hook
then swap out the ent's vtable ptr (which I've had no luck with,
honestly), or hook all ents of that type by just modifying it's vtable
directly (which I've had luck with).

RE: [hlcoders] Server Plug-in Loading Order
They are loaded just after the DllInit() call to the game server dll.

RE: [hlcoders] Server Plug-in Loading Order
Alfred, Thank you for the quick reply. At 05:40 PM 2/19/2005, you wrote: They are loaded just after the DllInit() call to the game server dll. What are you doing that requires a particular ordering of load? So the Game DLL's - DLLInit() is called, passing in the engine interfaces and what have you. Then any server plug-ins specified in the mods '/addon' folder get their DLLInit() calls. Then the map begins loading and we start spawning game entities ? The reason I asked is because I am considering some really evil low-level [EMAIL PROTECTED] in order to provide some of the the API hooking functionality that Metamod provided which the server plugin interface does not. Particularly with regard to tracking the game DLL's entity creation and possibly modifying those entities as can be done with Metamod, but there are other ideas I have that are not very concrete yet. Mostly, I'm scoping out capabilities at the moment. - Alfred -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Michael A.

Re: [hlcoders] Server Plug-in Loading Order
What sort of low level hacks are you considering? You may want to look into what Pavol Marko did for SourceMod, a general manager for creating iterated lists of hooks to members in virtual interfaces: http://www.sourcemod.net/devlog/index.php?p=17 (this gives metamod style functionality for things like IVEngineServer and the GameDLL interface). Entities are a bit different, of course, because you need to hook non-virtual things (so far)... Lance can probably tell you more about this if you ask him nicely, he's done it :) ---David BAILOPAN Anderson http://www.sourcemod.net/ Michael Hobson wrote: Alfred, Thank you for the quick reply.

Re: [hlcoders] Server Plug-in Loading Order
Dave, Make your own damned threads to plug *your* mod on, please. Trying to hijack *my* thread is just plain rude. At 07:49 PM 2/19/2005, you wrote: What sort of low level hacks are you considering?
