How can I implement the chess rule where the white pieces always move first in my digital chess game?

Implementing the White Pieces First-Move Rule in a Digital Chess Game Using Unity

To implement the rule where the white pieces always move first in a digital chess game developed with Unity, follow these steps:

1. Define Player Colors

First, ensure that your player class or structure includes a color attribute. This will help you manage which player is controlling the white pieces:

New challenges and adventures await!

public class Player {
    public string Name { get; set; }
    public string Color { get; set; } // "White" or "Black"
}

2. Initialize Game Setup

At the start of your chess game, assign colors to the players strategically. Allow the white player to be designated and control the starting move:

Player whitePlayer = new Player { Name = "Player1", Color = "White" };
Player blackPlayer = new Player { Name = "Player2", Color = "Black" };
Player currentPlayer = whitePlayer; // White starts the match

3. Game Loop Logic

In your main game loop, check the current player’s color before allowing a move. If it’s the first move, ensure the white player is set:

// Main game loop
while (!gameOver) {
    if (currentPlayer.Color == "White") {
        AllowMove(currentPlayer);
    } else if(currentPlayer.Color == "Black") {
        AllowMove(currentPlayer);
    }
    currentPlayer = SwitchPlayer(currentPlayer);
}

The SwitchPlayer function toggles between the white and black players after a move:

private Player SwitchPlayer(Player currentPlayer) {
    return currentPlayer.Color == "White" ? blackPlayer : whitePlayer;
}

4. Enforcing First Move Rule

Ensure the starting condition enforces that the white player cannot change before any move occurs. This can be achieved by invoking the initial setting in a setup function:

void StartGame() {
    currentPlayer = whitePlayer; // Ensuring white starts
    StartMove(currentPlayer);
}

5. Testing and Validating

Test your game extensively to ensure the logic holds under all conditions, focusing on scenarios where white might inadvertently lose the first-move privilege.
