PHP код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER && GetPlayerState(playerid) != PLAYER_STATE_PASSENGER)
{
    if(newkeys & KEY_FIRE)
    {
        new Float:vx,Float:vy,Float:vz;
        GetVehicleVelocity(GetPlayerVehicleID(playerid),vx ,vy,vz);
        SetVehicleVelocity(GetPlayerVehicleID(playerid), vx * 1.8, vy *1.8, vz * 1.0);
    }
    if(GetPlayerState(playerid) != PLAYER_STATE_DRIVER)
    {
        if (newkeys & KEY_CROUCH)
        {
            new Float:x, Float:y, Float:z;
            GetVehicleVelocity(GetPlayerVehicleID(playerid),x, y,z);
            SetVehicleVelocity(GetPlayerVehicleID(playerid),x, y,z+0.3);
        }
    }
}
return 1;
}
