Struct amethyst::StateMachine

pub struct StateMachine<'a, T> { /* fields omitted */ }

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

Methods

impl<'a, T> StateMachine<'a, T>

pub fn new<S: State<T> + 'a>(initial_state: S) -> StateMachine<'a, T>

pub fn is_running(&self) -> bool

Checks whether the state machine is running.

pub fn start(&mut self, data: StateData<T>)

Initializes the state machine.

Panics

Panics if no states are present in the stack.

pub fn handle_event(&mut self, data: StateData<T>, event: Event)

Passes a single event to the active state to handle.

pub fn fixed_update(&mut self, data: StateData<T>)

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

pub fn update(&mut self, data: StateData<T>)

Updates the currently active state immediately.
