Technical Details
Framework & Cross-Platform Scaffolding
- Codebase Ownership: FNA source is copy-vendored directly into the repository, allowing direct engine modification and eliminating external dependencies.
- RID-Aware Deployment: Formulated MSBuild logic in the project build configuration to map native runtime libraries (win-x64, osx-x64, linux-x64) into build outputs based on target execution environment.
- SDL3 Platform Layer: Canonicalized SDL3 native libraries as the primary platform layer, providing native Wayland, modern controller, and macOS HiDPI support.
Render loops & Vector Fonts
- FontStashSharp Custom Adapter: Wrote a thin 75-line custom adapter to bridge FontStashSharp's platform-agnostic font processor to FNA's hardware drawing pipelines.
- On-the-Fly Rasterization: Avoided MonoGame content compiler pipeline overhead by using dynamic, runtime TTF vector font generation.

Retrospective
- Dependency Conflicts: Dragging in external game framework assemblies from NuGet causes type conflict errors. Clean, platform-agnostic packages combined with custom adapters preserve dependency isolation.
Vibe Check // Prompt Record
Developer:
“Vendor FNA so we own the platform layer. Configure MSBuild for win, mac, linux. Render spacecraft mesh.”
AI Agents:
FNA has been successfully copy-vendored. SDL3 native binaries mapped. Spaceship.glb wireframe rendered in the game window. Pre-push compilation gate set.
