you can't put a callback in the script and leave it without a calling function.. it's like nothing in the script.
use a timer, callback function that is called by the timer it's self.

pawn Код:

new vtimer;
public OnGameModeInit()
{
     vtimer = SetTimer("Dealercars", 100, true); // this timer for the dealercars callback, per 100 ms, and repeatable.
     return 1;
}

pawn Код:

public OnGameModeExit
{
     KillTimer(vtime);
     return 1;
}
