Time for action – building a GamePiece class: constructors

Add two constructors to your GamePiece.cs file after the declarations:

  public GamePiece(string type, string suffix)
  {
      pieceType = type;
      pieceSuffix = suffix;
  }

  public GamePiece(string type)
  {
      pieceType = type;
      pieceSuffix = "";
  }

What just happened?

A constructor is run when an instance of the GamePiece class is created. By specifying two constructors, we will allow future code to create a GamePiece by specifying a piece type with or without a suffix. If no suffix is specified, an empty suffix is assumed.

Updating a GamePiece

When a GamePiece is updated, you can change the piece type, the suffix, or both.
