Metamod plugin writing

I need a TUT for how to start make an metamod plugin step by step .I use msvc2010 and i tried again and again and always get errors and when is compiled then is not loaded by metamod on server .I tried even metamod/stub_plugin to compile and i dont did it. If anyone want to help me because I'm tired of trying get a good compiled plugin and this stop me from continue coding a metamod plugin.

Re: Metamod plugin writing

Example as mine:

C:\amxx\amxmodx-source
C:\amxx\metamod-1.19
C:\amxx\hlsdk-2.3-p3\

This pattern metamod plugin:

C:\amxx\metamod-1.19\stub_plugin\meta_api.cpp

Or for test:

PHP Code:


		
			
#include <extdll.h>

#include <meta_api.h>



plugin_info_t info = {

   META_INTERFACE_VERSION,            // ifvers

   "HELLO WORLD",                  // name

   "1.01",                        // version

   "2011/01/15",                  // date

   "--===((((][@KIRjkeeee))))===--",   // author

   "http://ultra.ucoz.ru",            // url

   "HELLOWORLD",                  // logtag, all caps please

   PT_ANYTIME,                     // (when) loadable

   PT_ANYPAUSE                     // (when) unloadable

};



enginefuncs_t g_engfuncs;



void WINAPI GiveFnptrsToDll(enginefuncs_t* pengfuncsFromEngine, globalvars_t *pGlobals)

{

   memcpy(&g_engfuncs, pengfuncsFromEngine, sizeof(enginefuncs_t));

}



C_DLLEXPORT int Meta_Query(char *interfaceVersion, plugin_info_t **pinfo, mutil_funcs_t *pMetaUtilFuncs)

{

   *pinfo = &info;

   ALERT(at_console, "[HELLOWORLD]: meta_query\n");

   return(TRUE);

}



C_DLLEXPORT int Meta_Attach(PLUG_LOADTIME now, META_FUNCTIONS *pFunctionTable, meta_globals_t *pMGlobals, gamedll_funcs_t *pGamedllFuncs)

{

   ALERT(at_console, "[HELLOWORLD]: meta_attach\n");

   return(TRUE);

}



C_DLLEXPORT int Meta_Detach(PLUG_LOADTIME now, PL_UNLOAD_REASON reason)

{

   ALERT(at_console, "[HELLOWORLD]: meta_detach\n");

   return(TRUE);

}

To compile it, you must open stub_mm.sln

C:\amxx\metamod-1.19\stub_plugin\msvc\stub_mm.sln

You need to add hlsdk folder

stub_plugin - properties - VC ++

You can add all

C:\amxx\hlsdk-2.3-p3\utils;
C:\amxx\hlsdk-2.3-p3\ricochet;
C:\amxx\hlsdk-2.3-p3\pm_shared;
C:\amxx\hlsdk-2.3-p3\network;
C:\amxx\hlsdk-2.3-p3\game_shared;
C:\amxx\hlsdk-2.3-p3\engine;
C:\amxx\hlsdk-2.3-p3\dmc;
C:\amxx\hlsdk-2.3-p3\dlls;
C:\amxx\hlsdk-2.3-p3\dedicated;
C:\amxx\hlsdk-2.3-p3\common;
C:\amxx\hlsdk-2.3-p3\cl_dll;

( multiplayer )

meta list will display like this:

PHP Code:


		
			
meta list

Currently loaded plugins:

      description      stat pend  file              vers      src   load  unlod

 [ 1] HELLO WORLD    RUN   -    stub_mm.dll       v1.01  ini   ANY   Pause

1 plugins, 1 running

I can not explain it better, because of my bad English

Re: Metamod plugin writing

I use msvc 2010

and about this

Code:

stub_plugin - properties - VC ++



You can add all



C:\amxx\hlsdk-2.3-p3\utils;

C:\amxx\hlsdk-2.3-p3\ricochet;

C:\amxx\hlsdk-2.3-p3\pm_shared;

C:\amxx\hlsdk-2.3-p3\network;

C:\amxx\hlsdk-2.3-p3\game_shared;

C:\amxx\hlsdk-2.3-p3\engine;

C:\amxx\hlsdk-2.3-p3\dmc;

C:\amxx\hlsdk-2.3-p3\dlls;

C:\amxx\hlsdk-2.3-p3\dedicated;

C:\amxx\hlsdk-2.3-p3\common;

C:\amxx\hlsdk-2.3-p3\cl_dll;

on stub_plugin - properties - VC ++ i found this

Code:

Executable Directories

Include Directories

Reference Directories

Library Directories

Source Directories

Exclude Directories

so where i add that folders ?

Re: Metamod plugin writing

i get compiled with this error

Code:

sdk_util.cpp(40): warning C4793: 'UTIL_LogPrintf' : function compiled as native :

    varargs not supported under /clr



sdk_util.cpp(44): warning C4793: 'UTIL_LogPrintf' : function compiled as native :

     Found an intrinsic not supported in managed code



sdk_util.cpp(46): warning C4793: 'UTIL_LogPrintf' : function compiled as native :

      Found an intrinsic not supported in managed code

this is what i found in sdk_util.cpp

Code:

void UTIL_LogPrintf( char *fmt, ... )

{

    va_list            argptr;

    static char        string[1024];

    

    va_start ( argptr, fmt );

    vsnprintf_s ( string, sizeof(string), fmt, argptr );

    va_end   ( argptr );



    // Print to server console

    ALERT( at_logged, "%s", string );

}

and on meta list i get this
[ 5] <stub_mm. badf load stub_mm.dl v - ini - -

Re: Metamod plugin writing

i tried now with no sdk_util.cpp

i get a clean compile but is still not loading my metamod plugin

Code:

[ 5] <stub_mm. badf load stub_mm.dl v - ini - -

how can i find where is the problem ?
it could be because of using msvc2010 on windows xp sp2 ?
when i compile amxmodx modules, are loaded. So where can be the problem ?

please someone help me ... i'm sick of it ...

Re: Metamod plugin writing

I will try my best to explain more clear

1.Property of your computer and add some new environment variables. as mine:
METAMOD
E:\AMX MOD X\METAMOD\metamod\
HLSDK
E:\AMX MOD X\hlsdk\multiplayer\
and save the setting.
2.Open the "stub_mm" project(just double click the "stub_mm.sln")
Propertries -> (All configurations) -> Configuration Propertries -> C/C++ -> General -> Additional include directories,for me:
$(METAMOD);$(HLSDK)\common;$(HLSDK)\engine;$( HLSDK)\dlls;$(HLSDK)\pm_shared

3.For the files:
sdk_util.cpp -- I think it was useless, so I delete it usually
h_export.cpp -- read the comment in the file:mrgreen:
meta_api.cpp -- you just need to edit your stub plugin information here.eg:

Code:

plugin_info_t Plugin_info = {
    META_INTERFACE_VERSION, // ifvers
    "minimal stub", // name
    "1.17", // version
    "2003/11/15",   // date
    "Will Day <[email protected]>",   // author
    "http://www.metamod.org/",  // url
    "STUB", // logtag, all caps please
    PT_ANYTIME, // (when) loadable
    PT_ANYPAUSE,    // (when) unloadable

};

OK, now let's start write out sample code for the metamod, I want to call ClientConnect,and it is a dll function, we can find it at the dllapi.cpp,so we can edit the file like this:

Code:

#include <extdll.h>



#include <dllapi.h>

#include <meta_api.h>



DLL_FUNCTIONS gFunctionTable;

BOOL Client_Connect_Pre_Hook(edict_t *pEntity, const char *pszName, const char *pszAddress, char szRejectReason[128])
{
    SERVER_PRINT("\n\n\tServer running stub_mm extension\n\t\"Client_Connect_Pre_Hook\" was call");
    RETURN_META_VALUE(MRES_IGNORED, TRUE);//ignored the return value.
}

C_DLLEXPORT int GetEntityAPI2(DLL_FUNCTIONS *pFunctionTable,
                              int *interfaceVersion)
{
    if(!pFunctionTable)
    {
        //GetEntityAPI2 called with null pFunctionTable
        return(FALSE);
    }
    else if(*interfaceVersion != INTERFACE_VERSION)
    {
        //! Tell metamod what version we had, so it can figure out who is out of date.
        *interfaceVersion = INTERFACE_VERSION;
        return(FALSE);
    }
    memset(&gFunctionTable, 0, sizeof(DLL_FUNCTIONS));

    gFunctionTable.pfnClientConnect = Client_Connect_Pre_Hook; // pfnClientConnect
    memcpy(pFunctionTable, &gFunctionTable, sizeof(DLL_FUNCTIONS));

    return(TRUE);

}

and compile it run the server with this plugin, connect to the server and you could see this on the server console

Re: Metamod plugin writing

Nice thread. Any similar tuts for linux?

Re: Metamod plugin writing

sorry for the Linux I only know a little about windows

Re: Metamod plugin writing

I'm having the same problem here. The stub plugin compiles fine with or without K.K.Lv's code in MSVC 2010 but refuses to load through metamod-p. I'm sure metamod-p is working properly because it loads other plugins without issue.

Does anyone have a working MSVC project for a basic plugin like the stub example?
