Setting a Timer, first:

pawn Код:

SetTimer("WantedLevel", 100000, false);

- I setted it at 100 seconds, change it, with your time wich you want to decrease level !

- Then we need to make a new public, from WantedLevel Timer;

pawn Код:

forward WantedLevel();

public WantedLevel()
{
    new playerid;
    SetPlayerWantedLevel(playerid,GetPlayerWantedLevel(playerid)-1);
}
