Ghost Commands

What is it?

A developer console for Unity. Slap a [Command] attribute on any method or property, and you can execute it from a command field in the editor and in-game. No setup required. It was born out of wanting a faster way to test and debug during game development.

• Turn any method or property into a command with a single attribute
• Works in both the editor console and in-game
• Suggestions and auto-completion with keyboard navigation
• Supports static and non-static methods, overloads, and optional parameters
• Add and remove commands dynamically at runtime
• Modern UI built with UI Toolkit, fully customizable

Architecture

Built around a custom parser that tokenizes command strings, a registry that discovers commands at startup, and an extensible framework where users create new commands by implementing a simple interface. I focused on breadth, implementing most of the 15+ built-in commands (camera, physics, scene, fog, lighting, player prefs, and more) through the same public API our users get.

Testing & CI

Some bugs only showed up on specific Unity versions, a fix that worked in 6000.2 could break in 6000.4. Catching that meant manually spinning up a fresh project, installing the package, and retesting every version by hand. I built a pipeline to automate it instead: every push to main runs the test suite I wrote across six Unity versions in parallel, so version-specific breaks get caught before an update ever ships.

• 110 tests covering command parsing, string conversion, and every built-in command
• Runs in parallel across 6 Unity versions on every push to main (our release branch), 660 test runs per pipeline
• Wrote a script to convert Unity's NUnit output into JUnit, so GitLab can parse and display results natively
• Per-version Library caching keeps each job under 8 minutes
• Code coverage tracked on every run
