Implementing a Simple Matchmaking System with Sockets in Python

In this tutorial, we will learn how to implement a simple matchmaking system using sockets in Python. A matchmaking system is used to match people together for a game, such as chess, number guessing, or pong, Based on their preferences and settings. We will split the tutorial into two parts:

1. Implementing a basic matchmaking system that matches people based on a simple STRING input.
2. Implementing a number guessing game with a central server that includes the matchmaking system.

1. Introduction

Welcome back! In today's video, we're going to learn how to implement a simple matchmaking system using sockets in Python. This system will allow us to match players together for various games based on their preferences and settings. Let's dive right into it!

2. Understanding Matchmaking Systems

2.1 What is a Matchmaking System?

A matchmaking system is a mechanism used in multiplayer games to match players together based on their preferences, skill levels, and other criteria.

2.2 The Basic Idea of Matchmaking Systems

The basic idea of a matchmaking system is to find suitable opponents or teammates for players based on their desired game settings. This could include factors such as the maximum number, the number of tries allowed, or specific roles in the game. The goal is to ensure a fair and enjoyable experience for all players involved.

2.3 Different Types of Matchmaking Systems

There are various types of matchmaking systems, ranging from simple string matching, as we will implement in the first part of this tutorial, to more sophisticated systems based on skill ratings, ranking systems, or algorithms that consider various factors to Create balanced matches.

3. Implementing a Simple Matchmaking System with Sockets in Python

In this section, we will implement a basic matchmaking system using sockets in Python. We will split the tutorial into two parts: setting up the client and setting up the server.

3.1 Setting Up the Client

To start, we will create a simple client script in Python. The client will connect to a localhost server on port 9999 and send a configuration string to the server. This configuration string will include the player's desired maximum number, number of tries, and role (guesser or decider).

import socket

# Create a TCP socket client
client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect(('localhost', 9999))

# Send the configuration string
config_string = f"{tries}-{max_number}-{role}"
client.send(config_string.encode())

# Receive and print the server's message
message = client.recv(1024).decode()
print(message)

# Enter input based on the user's role (guesser or decider)
if role == "guesser":
    input_string = input("Enter your guess: ")
else:
    input_string = input("Enter the number to be guessed: ")

# Send the input to the server
client.send(input_string.encode())

# Receive and print the match message or other updates from the server
match_message = client.recv(1024).decode()
print(match_message)

# Close the connection
client.close()

3.2 Setting Up the Server

Next, we will create the server script that handles client connections and performs the matchmaking logic. The server will listen for incoming connections, handle each client's connection, and match clients with compatible settings.

import socket
import threading

# Create a TCP socket server
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(('localhost', 9999))
server.listen()

# Define a list to store connected clients
connected_clients = []

# Function to handle client connections
def handle_client(client):
    # Send a prompt to the client
    client.send("Enter matching string:".encode())

    # Receive the matching string from the client
    matching_string = client.recv(1024).decode()

    # Look for a match among the connected clients
    found_match = False
    for i in range(len(connected_clients)):
        if connected_clients[i][1] == matching_string:
            # Found a match, create a new thread to handle the match
            threading.Thread(target=handle_match, args=(client, connected_clients[i][0])).start()

            # Remove the matched client from the list
            del connected_clients[i]

            found_match = True
            break

    if not found_match:
        # No match found, append the client to the list
        connected_clients.append([client, matching_string])

    # Close the client's connection
    client.close()

# Function to handle matches between clients
def handle_match(client1, client2):
    # Implement game logic here

# Main loop to accept client connections
while True:
    # Accept a client connection
    client, address = server.accept()

    # Handle the client connection in a new thread
    threading.Thread(target=handle_client, args=(client,)).start()

3.3 Handling Client Connections

In this part, we handle client connections in the server script. Each client connection triggers the handle_client() function, which receives the client's matching string and checks for a match among the connected clients. If a match is found, a new thread is created to handle the match. If no match is found, the client is appended to the list of connected clients.

3.4 Handling Matches

In the handle_match() function, we implement the game logic between the two matched clients. This is where You can define the rules of the game, receive input from the clients, and send game updates back to them.

4. Enhancing the Matchmaking System: Adding a Number Guessing Game

In this section, we will enhance the matchmaking system by adding a number guessing game. We will modify the client and server scripts to handle the game logic between matched clients.

4.1 Setting Up the Client

To begin, we update the client script to handle the number guessing game. The client will input their guess based on the configuration received from the server. They will continuously receive messages from the server, make guesses, and receive updates until the game is over.

# Same code as before...

# Enter the game loop
while True:
    # Receive a message from the server
    message = client.recv(1024).decode()
    print(message)

    # Check for keywords in the message to determine game status
    if "tries" in message or "lost" in message:
        break

    # Make a guess if the client is the guesser
    if role == "guesser":
        guess = input("Enter your guess: ")
        client.send(guess.encode())

# Close the connection
client.close()

4.2 Setting Up the Server

Next, we update the server script to handle the number guessing game between matched clients. We implement the game logic, including sending Prompts and receiving guesses from clients. The server will send match messages, inform clients of correct or incorrect guesses, and handle the end of the game.

# Same code as before...

# Function to handle matches between clients
def handle_match(client1, client2):
    # Get the configuration settings from the clients
    config1 = client1.recv(1024).decode().split('-')
    config2 = client2.recv(1024).decode().split('-')

    # Convert configuration settings to integers
    tries = int(config1[0])
    max_number = int(config1[1])

    # Determine the decider and guesser
    decider = client1
    guesser = client2

    if config2[2] == "decider":
        decider = client2
        guesser = client1

    # Send prompt to the decider
    decider.send("Enter the number to be guessed:".encode())

    # Receive the number to be guessed from the decider
    number = int(decider.recv(1024).decode())

    # Check if the number is within the valid range
    if number > max_number:
        # Invalid range, inform clients and terminate game
        decider.send("Invalid range".encode())
        guesser.send("Your partner messed up: invalid range".encode())
        decider.close()
        guesser.close()
        return

    # Start the game loop
    guess_counter = 0
    while True:
        # Increase the guess counter
        guess_counter += 1

        # Prompt the guesser for their guess
        guesser.send("Enter your guess:".encode())

        # Receive the guess from the guesser
        guess = int(guesser.recv(1024).decode())

        # Compare the guess to the number
        if guess == number:
            # Correct guess, inform clients and terminate game
            guesser.send(f"Correct! It took you {guess_counter} tries.".encode())
            decider.send(f"Your partner guessed correctly after {guess_counter} tries.".encode())
            guesser.close()
            decider.close()
            return
        else:
            # Incorrect guess, inform clients
            if guess < number:
                guesser.send("Your guess is too low. Try again.".encode())
            else:
                guesser.send("Your guess is too high. Try again.".encode())
            decider.send(f"Your partner guessed {guess}.".encode())

    # Close the client connections
    guesser.close()
    decider.close()
