Fusion is a game engine written in C++ that I'm mainly working on as a hobby project, when I'm not working at my day job (where I'm also working on an engine).

Fusion is a game engine written in C++ that I'm mainly working on as a hobby project, when I'm not working at my day job (where I'm also working on an engine).

The main goal of Fusion is for me to expand my knowledge in game engine architecture, graphics programming, as well as learning more about programming in general.

Since this is a hobby project you should keep in mind that I constantly break it. And will make arbitrary choices based on personal preference, not strictly what's best practice. I highly recommend that you don't use Fusion for anything other than checking it out!

Roadmap

• Finish Direct3D 11 + Direct3D 12 API abstractions (and ensure they're stable)
• Refactor actor selection system (including proper selection using mouse picking)
• Fix up editor UI a bit
• Convert textures to be assets + texture importing
• Implement a simple material system
• Implement a basic physically-based renderer
• Initial physics implementation (Consider either Jolt, PhysX 5 or custom)

Building

Fusion uses Premake as a build configuration system, meaning Fusion in theory works with whatever toolchains / compilers that premake supports. However the only compilers / toolchains I've actually tested Fusion on are these:

Currently Fusion only supports Windows, which is made apparent by it only support Direct3D as a graphics API. Vulkan support is planned for the future however, and I do plan on supporting Linux down the line.

Compilers

• MSVC
• Clang

Toolchains

• Visual Studio 2022

Building on Windows

Either run the GenerateProjects.bat file located in the Scripts folder, or if you have premake installed locally (and it's in your PATH environment variable) you can just run premake5.exe [action] --cc=desired_compiler from the root directory.
