Understanding the Game

Musical Chairs is a beloved party game that combines fun and strategy. Players walk in a circle around a set of chairs while music plays in the background. However, when the music stops, the real excitement begins. Players must quickly find a chair to sit in. The catch? There are fewer chairs than players. The player left standing without a chair is eliminated from the game. This process repeats until only one player remains victorious.

Prerequisites

Before you embark on this coding journey, make sure you have Haskell installed on your computer. If you haven't already, you can download Haskell from the official Haskell website.

Implementation Breakdown

Let's break down the implementation of Musical Chairs into several key components:

Player Data Type

```haskell data Player = Player { playerName :: String } deriving (Show, Eq) ```

We begin by defining a `Player` data type to represent each participant in the game. Each player has a unique name.

Game State Data Type

```haskell data GameState = GameState { players :: [Player] -- List of players still in the game , currentRound :: Int -- Current round number , rng :: StdGen -- Random number generator } deriving (Show) ```

The `GameState` data type holds crucial information about the game, including the list of active players, the current round number, and a random number generator.

Initializing the Game State

```haskell initGameState :: [String] -> IO GameState ```

Our next step is to create the `initGameState` function, responsible for initializing the game state. This function takes a list of player names as input and sets up the initial state of the game.

Playing a Round

```haskell playRound :: StateT GameState IO () ```

The `playRound` function is where the action happens. It simulates one round of the game, including shuffling the list of players, eliminating one player, and updating the game state accordingly.

```haskell runMusicalChairs :: [String] -> IO () ```

Our `runMusicalChairs` function serves as the entry point for running the game. It sets up the initial game state and begins the gameplay by calling `playRound`.

Shuffling Helper Function

```haskell shuffle :: ([a], StdGen) -> ([a], StdGen) ```

To keep our code organized, we've created a `shuffle` function that uses the Fisher-Yates algorithm to shuffle a list. This function ensures a random order for our players in each round.

Running the Game

To start the Musical Chairs game, simply call the `runMusicalChairs` function with a list of player names. The game will continue until only one player remains.

```haskell runMusicalChairs ["Alice", "Bob", "Charlie", "David", "Eve"] ```

Conclusion

In this guide, we've taken you through the process of implementing a simplified version of Musical Chairs in Haskell. This example showcases how Haskell's functional programming features can be applied to model and simulate a game. Whether you're using this code as a starting point for more complex game development or as an educational exercise to deepen your understanding of Haskell, we hope you find it both enjoyable and informative.
