Sure, i use also an own include and i use OnPlayerKeyStateChange callback there with hooking.
On my Gamemode i don't have anything and here's my include.

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if(PRESSED(KEY_FIRE) || PRESSED(KEY_JUMP))
    {
        TextDrawHideForPlayer(playerid, Stats[playerid]);
    }
    return CallLocalFunction("menu_OnPlayerDisconnect", "iii", playerid, newkeys, oldkeys);
}

#if defined _ALS_OnPlayerKeyStateChange
    #undef OnPlayerKeyStateChange
#else
    #define _ALS_OnPlayerKeyStateChange
#endif
#define OnPlayerKeyStateChange menu_OnPlayerKeyStateChange
forward menu_OnPlayerKeyStateChange(playerid, newkeys, oldkeys);

Nothing too much and i don't see any error there.
