Cobalt Engine

Cobalt Engine is a 2D game engine written in C++ using SDL3 and SDL3 GPU. It is a personal long-term hobby project for learning and experimentation rather than a commercial engine.

Note

The engine is currently in an early stage and not yet capable of making games.

Platform support

• Windows
• Linux

Note

Only tested on Fedora Workstation 44 and CachyOS

Roadmap

The primary goal for version 0.1 is to make the engine capable of creating a simple game through its editor.

• Asset management
• Input
• Scripting
• Audio
• Physics
• Runtime GUI
• Building and Packaging
• Project launcher

Building

Requirements

• CMake ≥ 3.24
• C++ Compiler supporting C++23
  • MSVC (Visual Studio 2022)
  • Gcc ≥ 11
  • Clang ≥ 18
• Ninja (optional)

Clone the repository

git clone --recursive https://github.com/Resongeo/Cobalt-Engine

Change directory

cd Cobalt-Engine

If you’re building from an IDE, use its built-in CMake tools to configure and build the project. For manual builds, run the following commands:

Configure the project:

cmake --preset debug

Build the project:

cmake --build --preset engine-debug

For a minimum size release build:

cmake --preset min-size-release
cmake --build cmake-min-size-release

AI Usage

AI tools are used as a support aid for research, build system setup, and library recommendation. They are not used for code generation, agentic development workflows, or code completion. All code in this project is written by hand.
