From what I saw on your pawn code, your mistake is you identified Barrierdown in this script:

pawn Код:

barrierdown = CreateObject(968,1810.89941406,-1882.89941406,13.60000038,0.00000000,90.00000000,269.99450684); //object(barrierturn) (1)

Now, I looked at the cords, the find that they match exactly int his pawn code:

pawn Код:

CMD:rentcar(playerid, params[])
{
    MoveObject(barrierdown, 1810.89941406, -1882.89941406, 13.60000038, 2.0);
    return 1;
}

Meaning it is not actually moving, but is practically despawning, where you have MoveObect(barrierdown, 1810.89941406, -1882.899414406, 13.60000038, 2.0) You should replace the cords with where you want them to be, rather than where they currently are.

Hope I helped.
