hook problem - Sanady - 06.02.2016

Hey, I tried hook function with ALS method, but when I do hook, I get warning that symbol already exsists here is the code:

pawn Код:

#if defined _ALS_OnPlayerEnterDynamicRaceCP
    #undef OnPlayerEnterDynamicRaceCP
#else
    #define _ALS_OnPlayerEnterDynamicRaceCP
#endif
#define OnPlayerEnterDynamicRaceCP dym_OnPlayerEnterRaceCP
forward dym_OnPlayerEnterRaceCP(playerid, checkpointid);

public OnPlayerEnterDynamicRaceCP(playerid, checkpointid)
{
    CallLocalFunction("dym_OnPlayerEnterRaceCP","ii");
    return 1;
}

public dym_OnPlayerEnterRaceCP(playerid, checkpointid)
{

    return 1;
}

You won't be able to hook such large callback names because samp allows only 31 characters for a deceleration/element.

You have to use ALS method, by cutting some part of the callback's name while hooking.

Is possible to change 31 characters of deceleration/element?

Sorry for bump but I need really help.

Re: hook problem - Nero_3D - 07.02.2016

The ALS hook must be after the function!, also use hook method 7
The reason is simple because you redefine the function name

PHP код:



public OnPlayerEnterDynamicRaceCP(playerid, checkpointid)

{

    #if defined dym_OnPlayerEnterRaceCP

        return dym_OnPlayerEnterRaceCP(playerid, checkpointid);

    #else

        return true;

    #endif

}


#if defined _ALS_OnPlayerEnterDynamicRaceCP

    #undef OnPlayerEnterDynamicRaceCP

#else

    #define _ALS_OnPlayerEnterDynamicRaceCP

#endif

#define OnPlayerEnterDynamicRaceCP dym_OnPlayerEnterRaceCP

#if defined dym_OnPlayerEnterRaceCP

    forward dym_OnPlayerEnterRaceCP(playerid, checkpointid);

#endif


// in another file

public OnPlayerEnterDynamicRaceCP(playerid, checkpointid)

{

    return true;

}
