Creating a Text-Based Chess Game in C#

Explore our comprehensive guide on creating a text-based chess game in C#. Whether you're a beginner or an experienced programmer, this guide will help you enhance your skills and provide invaluable assistance with your C# assignment. Master the art of game development while crafting captivating text-based gaming experiences. Our step-by-step instructions and detailed code explanations make it easy for you to grasp the intricacies of C# game development, ensuring you have the knowledge and expertise to tackle your programming assignments with confidence.

Block 1: Class Definition and Fields

```csharp public class GameBoardClass { char[][] state; int score = -100000; } ```

This code block defines the `GameBoardClass`, the heart of our game. It contains two crucial fields: `state`, which represents the game board as a 2D character array, and `score`, initialized to a very low value.

Block 2: `ToString` Method

```csharp public string ToString() { string result = ""; for (int i = 0; i < 9; i++) { for (int j = 0; j < 9; j++) result += state[i][j]; result += '\n'; } return result; } ```

The `ToString` method generates a visual representation of the game board. It loops through the `state` array and converts it into a string for debugging and display purposes.

Block 3: `SCORE` Property

```csharp public int SCORE { get { if (score == -100000) score = GetScore(this); return score; } } ```

The `SCORE` property calculates and returns the score of the game board. If the score hasn't been computed already, it utilizes the `GetScore` method to do so.

Block 4: Constructors

```csharp public GameBoardClass(string[] vs) public GameBoardClass(GameBoardClass gB) private GameBoardClass() ```

These constructors create instances of `GameBoardClass`. The first constructor initializes the game board from a string array, the second constructs a copy from an existing instance, and the third constructor is private and not intended for general use.

Block 5: `Reverse` Method

```csharp public GameBoardClass Reverse() { GameBoardClass gb = new GameBoardClass(); gb.state = new char[9][]; for (int i = 0; i < 9; i++) { gb.state[8 - i] = new char[9]; for (int j = 0; j < 9; j++) { char piece = this.GetPiece(i, j); if (IsAlly(piece)) piece = (char)(piece - 'a' + 'A'); else if (IsEnemy(piece)) piece = (char)(piece - 'A' + 'a'); gb.SetPiece(8 - i, j, piece); } } return gb; } ```

The `Reverse` method returns a new `GameBoardClass` that's a mirror image of the current board. Uppercase and lowercase pieces are swapped in the process.

Block 6: Piece Manipulation Methods

These methods allow you to get, set, swap, and change pieces on the game board. They offer various ways to manipulate the board:

  • `GetPiece(int r, int c)`
  • `SetPiece(int r, int c, char ch)`
  • `Go(int r, c, int nr, int nc)`
  • `Swap(int r, c, int nr, int nc)`
  • `Change(int r, int c)`
  • `Go(PointClass now, PointClass nxt)`
  • `IsEmpty(int r, int c)`
  • `IsEmpty(PointClass pos)`

Block 7: `IsSentinelNearHere` Methods

These methods check if a sentinel piece is near a specific location. They are used to identify nearby sentinel pieces on the board:

  • `IsSentinelNearHere(int r, int c)`
  • `IsSentinelNearHere(PointClass pt)`

Block 8: Utility Methods

These methods serve to check various conditions related to pieces and positions on the board. They're crucial for game logic:

  • `IsEnemy(char c)`
  • `IsAlly(char c)`
  • `IsOutPosition(int r, int c)`
  • `IsEmpty(char c)`

Block 9: `GetScore` Method

```csharp public static int GetScore(GameBoardClass gB) { int score = 0; int ws = 0, bs = 0; for (int i = 0; i < 9; i++) { for (int j = 0; j < 9; j++) { char piece = gB.state[i][j]; switch (piece) { case 'z': bs += ZombiesClass.GetScore(); break; case 'Z': ws += ZombiesClass.GetScore(); break; case 'b': bs += BuilderClass.GetScore(); break; case 'B': ws += BuilderClass.GetScore(); break; case 'm': bs += MinerClass.GetScore(); break; case 'M': ws += MinerClass.GetScore(); break; case 'j': bs += JesterClass.GetScore(); break; case 'J': ws += JesterClass.GetScore(); break; case 's': bs += SentinelClass.GetScore(); break; case 'S': ws += SentinelClass.GetScore(); break; case 'c': bs += CatapultClass.GetScore(); break; case 'C': ws += CatapultClass.GetScore(); break; case 'd': bs += DragonClass.GetScore(); break; case 'D': ws += DragonClass.GetScore(); break; case 'g': bs += GeneralClass.GetScore(); break; case 'G': ws += GeneralClass.GetScore(); break; default: break; } } } score = bs - ws; return score; } ```

This static method calculates the score of the game board. It iterates through all pieces on the board and calculates scores based on piece types using `GetScore` methods from other classes.
