Blindspot: Online 3:3 top-down tactical shooter game

About

• Blindspot is a dedicated game server and client project designed for a 3:3 top-down tactical shooter.
• This project is still a work in progress.

Features

1.Asynchronous Networking

• Built with Boost.Asio for high-performance, non-blocking I/O operations.
• Handles multiple concurrent connections using a scalable Session-based architecture.

2. Robust Packet Serialization

• Utilizes Google Protocol Buffers (Protobuf) for efficient and structured data exchange between server and client.
• Automated packet handling system with a custom PacketHandler.

3. Security-Conscious Design

• Session-Key Authentication: Implements a token-based session management system to prevent Player ID spoofing.
• Server-Side Authority: All critical game logic (movement, room management) is validated on the server to prevent client-side manipulation.

4. Thread-Safe Game Logic

• Managed concurrency using modern C++ features: std::atomic, std::mutex, and std::shared_ptr.

Tech Stack

Server (C++)

Language: C++20

Networking: Boost.Asio

Serialization: Protobuf

Build System: vcpkg

Client (Unity)

Engine: Unity

Language: C#

Networking: TCP Socket communication

System Architecture

The server follows a modular architecture to separate networking, logic, and data management:

Network Layer: Manages raw TCP sockets and packet framing.

Session Layer: Handles individual connection states and authentication tokens.

Logic Layer (Room/Player): Manages game rooms, matchmaking, and player metadata.

Packet Handler: Dispatches incoming packets to their respective logic functions.

Getting Started

Prerequisites

Server: Visual Studio 2026, Boost, Protobuf

Client: Unity Hub, Unity 6000.3.3f1

Installation

Clone the repository:

git clone https://github.com/ryujm1828/BlindSpot.git

Build the Server:

Server Setup (C++)

1.Clone the repository:

git clone https://github.com/YourUsername/Habitus.git

2.Install Dependencies via vcpkg: Open your terminal/PowerShell and run:

vcpkg install boost-asio:x64-windows protobuf:x64-windows

3.Integrate vcpkg with Visual Studio:

vcpkg integrate install

4.Open the Solution:

Navigate to the Blindspot_Backend folder.

Double-click the Habitus.sln file to open it in Visual Studio.

5.Build & Run:

Set the solution configuration to Debug or Release and the platform to x64.

Press F5 or click Start to run the server.

Run the Client:

Open the Blindspot_Frontend folder in Unity.

Ensure the server address is set to 127.0.0.1.
