MagmaCraft

A Custom Voxel Multiplayer Game

MagmaCraft is a voxel-based sandbox game built entirely from scratch using C++ and OpenGL. Built upon my Magma Framework, it serves as a technical showcase of voxel rendering, client-server networking, and entity management.

Key Features

• Custom Voxel Engine: Multithreaded chunk rendering, texture atlasing, and world streaming.

• Multiplayer Networking: Robust client-server architecture with the help of ENet.

• Supports Hosting and Joining worlds.

• Entity interpolation for smooth movement across the network.

• Real-time player synchronization and connection handling.

• 3D Rendering: Custom rendering pipeline supporting FBX model loading, shaders, and dynamic textures.

• World Management: Infinite terrain generation with chunk compression and saving/loading systems.

• User Interface: ImGUI for server browsing, login, and in-game crosshair using Low Level Game Dev's GLUI library.

Tech Stack

• Language: C++ (C++20)
• Graphics: OpenGL 4.6
• Networking: ENet
• Windowing/Input: SDL3
• Math: GLM
• Build System: CMake

Getting Started

MagmaCraft uses CMake for cross-platform building.

1. Clone the Repository (Ensure you have Visual Studio or a C++ compiler installed).
2. Open Visual Studio and select File -> Open -> CMake Project.
3. Navigate to the repository folder and select CMakeLists.txt.
4. Allow CMake to configure the project (dependencies are managed via Vcpkg or submodules where applicable).
5. Select MagmaCraft.exe as the startup item and run!

Note: Ensure the resources folder is in your working directory or next to the executable for textures and models to load correctly.

Controls

• W, A, S, D: Move
• E, Q: Fly up and down
• Mouse: Look
• Esc: Release Mouse
