[written by Claude Code w/Opus 4, guided by me (David Cornelson)] When players type "TAKE COIN" in an IF game, what seems like a simple command actually triggers a sophisticated chain of questions: Can the player see the coin? Can they reach it? Do they even know

Sometimes you're testing code and go through the pipeline of connected code and realize something just "smells wrong". emitSuccess() - for success events with messages emitError() - for error events with messages emit() - for generic events emitMany() - for multiple events at once createEvent() -

When I designed the world model, I decided to implement a pattern that separates behavior from data. These are called Traits. If you apply the Pulling Trait to an entity, it will have all the necessary logic to handle being pulled. Initially the Pulling action in standard library had logic

In a previous post I got a little carried away with all the great testing results, but that ran into an expected wall. Unit and integration tests are meant to validate your architecture and code and expose gaps. Well we discovered a few gaps and it took us a minute

Now sure if this is true in other platforms like Inform or TADS, but while designing Sharpee it became clear that the Parser makes a ton of assumptions about vocabulary and command structure that are directly tied to the language the author is using to tell their interactive story. I

In the midst of testing the platform (everything is building and Core, IF Domain, Event Processor, World Model, lang-en-us, Standard Library, and Engine all compile), there were some actions without clear implementations. For scoring, where do we keep that data? In the player entity? In the world model at some

I've copied the ADRs to the GitHub repository. You can view them here: https://github.com/ChicagoDave/sharpee/issues

So we ran into a goofy problem that would only happen in a modern architecture. Encapsulation is something IF development has rarely adhered to and Sharpee leans into it. The event source and spatial indexing (the implemented world model) have event-based interfaces and you currently can't change things
