FastSM

FastSM is a finite state machine (FSM) library for GameMaker that provides a more lightweight alternative to SnowState. It employs different design paradigms that offer greater flexibility in certain scenarios while imposing specific limitations to maintain performance and simplicity. ## Key Features - **State Management** — Define states with enter/update functions and assign tags for categorization - **Trigger System** — Create triggers with include/forbid rules to control state transitions - **Event Handling** — Add custom events like "update" that can be called on active states - **Tag-based Organization** — Assign up to 64 tags to states for grouping and filtering - **Transition Control** — Configure allowed and forbidden state transitions per trigger ## Philosophy FastSM prioritizes simplicity and performance with explicit limitations, making it suitable for projects where a lightweight FSM implementation is preferred over feature-rich alternatives.
