Overrideing variables

Question

Hello I'm trying to figure out how to override variables spawned in a derived class that are declared in a base class. For instance: public class construct { public bool DENSITY = false ; } public class mob : construct { DENSITY = true; } Is this possible with some sort of modifier or something or do I have to change DENSITY in a method/function/procedure/sub-routine (what name do C# programmers use?) in the derived class?

FWIW you can hide a variable declared in a parent class by declaring a similarly named variable in a child class and preceding it with the 'new' keyword. You can still access the parent class variable either by using a cast or (within the child class code) by using the 'base' keyword. For example: using System; class Program { static void Main() { mob m = new mob(); Console.WriteLine(m.DENSITY); // true Console.WriteLine(((construct)m).DENSITY); // false Console.WriteLine(m.BaseDensity); // false m.BaseDensity = true; Console.WriteLine(m.BaseDensity); // true Console.ReadLine(); } } public class construct { public bool DENSITY = false; } public class mob : construct { public new bool DENSITY = true; public bool BaseDensity { get {return base.DENSITY;} set {base.DENSITY = value;} } }

You have to change it in a method. For exposing public variables it's better to expose it as properties instead. IMHO.
