You could run it in OnPlayerUpdate() tho it will be ran very often.

Edit: This will fuck up your script..

Код:

new Float:health;
        GetPlayerHealth(playerid,health);
        if (health < 1000)
        {
            SetPlayerHealth(playerid, 100);
        }
    }
   
    return 1;
}

Remember health is a Float. Also this will set your health to 100 like all the time, should probably add a zero(0) at the SetPlayerHealth().
