## 🔄 Bookshelf Finite State Machine Module Describe behaviors as states and transitions, and run them on entities or globally. > *"FSMs are without a doubt the most commonly used technology in game AI programming today. They are conceptually simple, efficient, easily extensible, and yet powerful enough to handle a wide variety of situations."* > > — Daniel D. Fu & Ryan Houlette ### ✨ Features - Describe a state machine as a template, stored and edited with plain data commands - Validate a state machine before running it (initiality, unicity, acceptability, reachability) - Run a state machine globally or bound to specific entities - Trigger transitions manually, or from a predicate, a command, or a delay - React to state changes with enter, tick, and exit commands 📚 [Documentation](https://docs.mcbookshelf.dev/en/latest/modules/fsm.html) ## About Bookshelf This module is part of the Bookshelf library: 🧩 Find more in the [Bookshelf Organization](https://modrinth.com/organization/mcbookshelf) \ 📦 Get the full [Bookshelf Suite](https://modrinth.com/datapack/bookshelf-suite) ## Get involved 💬 Join our [Discord](https://discord.gg/MkXytNjmBt) \ 🛠 Learn how to [contribute](https://docs.mcbookshelf.dev/en/latest/contribute/)
