What is the ZX FFI Reference skill?

It is a specialized extension for Claude Code that provides documentation and implementation guidance for the ZX console's Foreign Function Interface (FFI).

Which programming language does this skill support?

This skill focuses on the ZX console API, which uses Rust-style bindings (zx.rs) for its system, rendering, and input functions.

Does it cover 3D rendering functions?

Yes, it includes detailed references for meshes, textures, materials, camera settings, and 3D transform stacks using a Y-up, right-handed coordinate system.

How does it help with debugging lifecycle errors?

The skill provides specific rules on function timing, distinguishing between functions that must be called during initialization (like set_tick_rate) versus those only allowed during the render loop (like draw_mesh).

Game Development

Provides comprehensive API documentation and implementation patterns for the ZX console FFI bindings.

About

This skill equips Claude with specialized knowledge for the ZX console environment, offering instant access to over 250 FFI functions across categories like 3D rendering, input handling, audio processing, and system management. It streamlines the development process by enforcing correct API usage patterns, such as distinguishing between initialization-only and render-loop-only functions, while providing clear templates for asset loading, coordinate transform stacks, and 3D mathematics within the ZX ecosystem.

Key Features

Quick-lookup for system, debug, and 2D/3D rendering APIs
Access to 250+ ZX console FFI function signatures and categories
Guidance on lifecycle-specific function usage for Init vs. Render loops
Standardized patterns for asset loading including textures, meshes, and audio
Detailed reference for 3D transform stacks and right-handed coordinate systems
1 GitHub stars

Use Cases

Building high-performance 3D games or applications using the ZX console engine
Debugging FFI call signatures and resolving lifecycle timing errors
