1. This was the old implementation of the modifier system

Player_Manager.cs

public void CheckStatsForDebuffs() //
    {
        Sluggishness();
        ShortSightedness();
    }

    //Debuffs and Buffs
    private void Sluggishness() //Every modifier was a function in the Player_Manager Script
    {
        if (current_Hunger_Level < 90) //Inside every function they had their threshold check, in this case checking if
        {                                       //if hunger is below 90
            current_Speed =  Max_Speed*.5f;
        }
        else
        {
            current_Speed = Max_Speed;
        }
    }  

    private void ShortSightedness() //This is another modifier
    {

        if (current_Water_Level < 90)
        {
            Player_Camera.orthographicSize = 2.5f;
        }
        else
        {
            Player_Camera.orthographicSize = 5;
        }

    }
}
