I don't understand you but you need to try this:

PHP код:

public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if(oldstate == PLAYER_STATE_ONFOOT && newstate == PLAYER_STATE_DRIVER)
    {
        SetPlayerArmedWeapon(playerid, 0);
    }
    if(oldstate == PLAYER_STATE_ONFOOT && newstate == PLAYER_STATE_PASSENGER)
    {
        SetPlayerArmedWeapon(playerid, 0);
    }
    return 1;
} 


When player enter in vehicle as driver or passenger, it select his weapon to 0 (Don't reset, just select) and he cannot shot.
