Unity-Python-TCP-Server

Project Overview

This project includes a server and a client script for a decentralized peer-to-peer network game. The server, implemented in Python as unityserver.py, facilitates communication between multiple clients, allowing them to interact with each other in the game. The C# client script TCPClient.cs is designed for Unity and connects to the server via TCP for data exchange.

The server is responsible for handling incoming client connections, client authentication, peer-to-peer communication setup, data synchronization, error handling, and security measures.

The client is a Unity TCP client that can connect to the server and receive data. It is designed to be efficient, robust, and easily integrated into Unity projects.

Server Features

The unityserver.py script includes the following features:

• Server Setup: Sets up a Python server socket to listen for incoming client connections. The server can run continuously, accepting connections from multiple clients without interrupting the gameplay experience.

• Client Authentication: Implements a secure client authentication mechanism to ensure only legitimate clients can connect to the server. You can customize the authentication logic to suit your game's requirements.

• Peer-to-Peer Communication: Handles communication between clients in a peer-to-peer manner. The server facilitates the initial connection and communication setup, but the actual communication between clients is direct and decentralized.

• Data Synchronization: Manages synchronization of game data between connected clients. This includes handling player actions, positions, game state, and other relevant gameplay information that must be consistent across all players.

• Error Handling and Logging: Implements robust error handling mechanisms to handle potential issues such as client disconnections or network errors. Logging functionality records server activities and errors for debugging purposes.

• Security Measures: Includes necessary security measures to protect the server and clients from potential security threats, such as unauthorized access, data tampering, or denial-of-service attacks.

Client Features

The TCPClient.cs script includes the following features:

• TCP Communication: Implements a TCP client for Unity that can establish and maintain a reliable connection to the server. The client can send and receive data in a structured format.

• Data Serialization: Provides a basic data serialization mechanism for converting complex data structures (e.g., JSON, binary) into a format suitable for transmission over TCP. You can customize this serialization based on your specific data requirements.

• Error Handling: Implements proper error handling to address various scenarios, such as connection failures, data corruption, and server unavailability.

• Threading: Uses appropriate threading mechanisms to handle TCP communication without blocking the main Unity thread. This ensures a smooth user experience and prevents application freezes.

• Callbacks/Events: Designed to use callbacks or events to notify other parts of the Unity application when new data is received or the connection status changes.

Installation

1. Clone this repository to your local machine using Git:

git clone https://github.com/agx-r/Unity-Python-TCP-Server.git

2. For the Python server script, ensure you have Python 3.x installed. No additional dependencies are required.

3. For the Unity client script, open your Unity project and place the TCPClient.cs script in the appropriate Unity project folder.

Usage

1. Start the Python server:

python unityserver.py

2. In Unity, attach the TCPClient.cs script to an empty GameObject.

3. Customize the unityserver.py and TCPClient.cs scripts according to your game's specific needs.
