bevy_fsm

What problem does this crate solve?

A safe finite state machine. Instead of churning components and manually ensuring that only one state can be active at a time, variants of a single enum are used as FSM. Comes with mechanisms for observing and executing state transitions.

Features

• Transitions rule controls
• Component for per-entity override for the rules
• State enter, exit, and transition events for handling logic
• Paired with a crate for converting each variants into a separate type for event handling
