Submitted by user gklompje; MIT; 2026-05-11

An extensible, graph-based state machine framework for Godot. Features a visual editor, composition-based behaviors, nested machines, and built-in persistence.

Key Features:
- Graph-based UI: Create and edit complex state transitions visually.
- Composition-over-Inheritance: Extensible behavior framework for adding logic to states.
- Decoupled Logic: Model state flow independently from the scene tree.
- Visual Data Tracking: Track how data and signals flow through your machine at a glance.
- Blackboard System: Share parameters easily between states and other game systems.
- Built-in Persistence: Native saving and loading support.
- Nesting: Sub-state machines for modular, reusable logic.
