SyzygyEngine

SyzygyEngine is a Windows-focused C++20 game engine with a DirectX 12 renderer, scene-based runtime framework, and integrated debug/editor tooling.

The repository is designed to be used with the included project generator, which creates a full game solution that references this engine as a submodule.

Engine features

Features

• DirectX 12 rendering pipeline with Shader Model 6.6
• Scene-driven runtime flow (initialize, setup, update, draw, finalize)
• Render DAG-based rendering path configuration
• Built-in asset systems for:
  • Meshes
  • Textures
  • Shaders
  • Audio
  • Skeleton and node animation
  • Primitive
• Background asset loading
• Debug/editor mode (ImGui-based) with:
  • Hierarchy and scene view tools
  • Asset browser and asset import helpers
  • Render DAG editor
  • In-editor log window
• Configurable project settings via JSON (window, graphics, frame settings)

Requirements

• Windows 11 / Visual Studio 2022 (MSVC v143)
• Windows SDK 10.0.26100.0 or compatible
• PowerShell, Git
• GPU with DirectX 12 support (Feature Level 12.0+, Shader Model 6.6, Bindless resources, Mesh Shader)

External Libraries

The engine includes and/or references the following libraries inside the repository:

• asio
• assimp
• DirectXTex
• freetype
• imgui (with ImGuizmo and ImNodeFlow extensions)
• msdf-atlas-gen
• nlohmann/json

Quick Start (Recommended)

1. Open a PowerShell terminal in a directory where you want to create your game project.
2. Download and run the generator script:

curl -o CreateSolution.ps1 https://raw.githubusercontent.com/TaiseiHamaya/SyzygyEngine/refs/heads/master/ProjectGeneratorTool/CreateSolution.ps1
.\CreateSolution.ps1 MyGame

3. Open the generated solution:

MyGame/project/MyGame.sln

4. Build with Visual Studio (x64, Debug / Develop / Release).

The generated solution includes:

• Game (your project, static library)
• SyzygyEngine (engine executable)
• DirectXTex
• imgui
• Asio
