If you want SMG only:

Under OnPlayerStateChange:

pawn Код:

if(newstate == 3) // Entered a vehicle as a passenger
{
    // Drive-by weapons (SMG only)
    new weaponid, ammo;
    GetPlayerWeaponData(playerid, 4, weaponid, ammo); // 4 is the SMG slot
    SetPlayerArmedWeapon(playerid, weaponid);
}
