Hi, II would do something like that, in gamemodzie gives:

Код:

native StartScript();

and every filterscripcie works:

Код:

public OnScriptInit()

//Edit

And how to take advantage of the MySQL plugin, for example, to retrieve the name of the item and return it.

Well, I guess it's better for you to stick with PAWN... But if you really want to create something using C++ functions I'd recommend this site -> http://www.cplusplus.com/

I KNOW you might not answer, but I happen to get 2 errors, tried some fixing, but no success, I'm a newbie @ VS.

Код:

error C2065: 'MyNat' : undeclared identifier
error C2365: 'MyNat' : redefinition; previous definition was 'formerly unknown identifier'

code

Код:

static cell AMX_NATIVE_CALL MyNat(AMX *amx, cell *params)
{  
    logprintf("Test, test :p.");
    return 1;
}

and

Код:

AMX_NATIVE_INFO projectNatives[] =
{
   { "MyNat", MyNat }
};

Re: How to create a plugin - RyDeR` - 17.05.2011

I have no idea why you get the error, but you shouldn't get it if you have done everything correctly. Just begin a new project and try again, should work!

Re: How to create a plugin - Raimis_R - 17.05.2011

I was searching something like this about 2 weeks.

Thanks RyDeR`!

Edit: where i can read about amx functions or something ho can help in dev plugin.

Like ur

pawn Code:

int __IsPlayerConnected(int playerid, AMX *amx) // AMX *amx must stay but it's just the playerid parameter that counts in his function.
{
    int
        index
    ;
    if(!amx_FindPublic(amx, "__IsPlayerConnected", &index))
    {
        cell
            retVal
        ;
        amx_Push(amx, playerid);
        amx_Exec(amx, &retVal, index);
        return (int)retVal;
    }
    return -1;
}

Where i can find like __IsPlayerConnected or this like stock in pawn?

Re: How to create a plugin - me-borno - 19.05.2011

Hello,

like -2000 becomes about 300 billion.. i already used float() int() etc. but nothing helps..
how to uses floats in c++

Ty in advance!

Solved, use amx_ctof or amx_ftoc

Re: How to create a plugin - Patrik356b - 21.05.2011

This tutorial is good, but the sdk seems to be a bit goofy, since the compiler complains about not finding amxplugin.h even after i choose to include all files. Tried with MS Visual C++ 2008

Re: How to create a plugin - 0x5A656578 - 21.05.2011

There's no amxplugin.h in it, did you mean amx.h?

Re: How to create a plugin - Patrik356b - 21.05.2011

No, my compiler asks for "amxplugin.h"

Will try to get around it by checking project settings and such

and

Code:

AMX_NATIVE_INFO projectNatives[] =

Put this:

pawn Code:

static cell AMX_NATIVE_CALL MyNat(AMX *amx, cell *params)
{  
    logprintf("Test, test :p.");
    return 1;
}

Before this:

pawn Code:

AMX_NATIVE_INFO projectNatives[] =
{
   { "MyNat", MyNat }
};

Re: How to create a plugin - 1337connor - 29.05.2011

1. I can't seem to get logprintf to work with a string for example
logprintf("%s",params[1]);
2. How do I make it say something when my plugin is loaded.

Re: How to create a plugin - iggy1 - 30.05.2011

You could use existing c++ libraries to write text to the console. Just a suggestion.

pawn Code:

#include <iostream>//at top

static cell AMX_NATIVE_CALL MyNat(AMX *amx, cell *params)
{  
    std::cout << "test " << params[1] << std::endl; // cout defined in iostream
    return 1;
}

1. Of course it won't work. You have to use "amx_StrParam(amx, params[1], buffer);". After this the data in params 1 will be in buffer.
2. Put it under "PLUGIN_EXPORT bool PLUGIN_CALL Load(void **ppData)"
