Csináltam az index rendszerhez egy textdrawot de nem jó mert nem jeleníti meg error nincs.
 

public OnPlayerKeyStateChange(playerid,newkeys,oldkeys)
{
if(GetPlayerState(playerid)==PLAYER_STATE_DRIVER)
{
    if(PRESSED(KEY_LOOK_LEFT)||PRESSED(KEY_LOOK_RIGHT))
    {
    new veh=GetPlayerVehicleID(playerid);
    if(index[veh][indexing])
    {
        DestroyObject(index[veh][obj1]);
        DestroyObject(index[veh][obj2]);
        TextDrawHideForPlayer(playerid, IndexbTextDraw);
        TextDrawHideForPlayer(playerid, IndexjTextDraw);
        index[veh][indexing]=false;
    } else {
        if(indexcompatible(veh))
        {
               new oldal2=(PRESSED(KEY_LOOK_LEFT))?1:0;
               indexf(veh,oldal2);
           TextDrawShowForPlayer(playerid, IndexbTextDraw);
           TextDrawShowForPlayer(playerid, IndexjTextDraw);
      }
   }
}
}
return 1;
}
