Aaaa... OK. Now I understand.

pawn Код:

CMD:hood(playerid, params[])

    new vehicleid,engine,lights,alarm,doors,bonnet,boot,objective;
    vehicleid = GetPlayerVehicleID(playerid);
    GetVehicleParamsEx(vehicleid,engine,lights,alarm,doors,bonnet,boot,objective);
    if(!IsPlayerInAnyVehicle(playerid))
        return SendClientMessage(playerid, COLOR_LIGHTRED, "Error: You are not in a vehicle.");
    if(GetPlayerVehicleSeat(playerid) != 0)
        return SendClientMessage(playerid, COLOR_LIGHTRED, "Error: You are not in the drivers seat.");
    if(bonnet == 1)
    {
        if(boot == VEHICLE_PARAMS_ON)

Actually, it's strange your problem because if you do that (let's suppose that hood is open and trunk closed):

pawn Код:

GetVehicleParamsEx(vehicleid,engine,lights,alarm,doors,bonnet,boot,objective);
//Return:          vehicleid,  0,      0,      0,     0,    1,  0,       0
//And we set them again with same values just changing trunk to true.
SetVehicleParamsEx(vehicleid,engine,lights,alarm,doors,bonnet,VEHICLE_PARAMS_on,objective);
//Everything else should be the same, except the trunk.
