Add this timer under OnGameModeInit() EDIT looks like the guy above me was quicker

pawn Код:

SetTimer("health", 1000, true); //this sets a timer to repeat every 1 seconds

paste this somewhere outside of any callback

pawn Код:

forward health();
public health()
{
     for(new i =0; i<MAX_PLAYERS; i++)
    {
            new Float:h = GetPlayerHealth(i);       
            if(health =< 20)
           {
                  SetPlayerHealth(i, health-5);
           }
       }
        return 1;
}
