Struct StateMachine

pub struct StateMachine { /* private fields */ }

A simple stack-based state machine (pushdown automaton).

Implementations

impl StateMachine

pub fn new<T>(initial_state: T) -> StateMachine

where T: State + 'static,

pub fn is_running(&self) -> bool

Checks whether the state machine is running.

pub fn start(&mut self)

Initializes the state machine.

Panics

Panics if no states are present in the stack.

pub fn handle_events(&mut self, events: &[i32])

Passes a vector of events to the active state to handle.

pub fn fixed_update(&mut self, delta_time: Duration)

Updates the currently active state at a steady, fixed interval.

pub fn update(&mut self, delta_time: Duration)

Updates the currently active state immediately.
