Most commonly used re-exported types.

Structs§

EnterSchedules
System set that runs enter schedule(s) for state S.
ExitSchedules
System set that runs exit schedule(s) for state S.
OnEnter
The label of a Schedule that only runs whenever State<S> enters the provided state.
OnExit
The label of a Schedule that only runs whenever State<S> exits the provided state.
OnTransition
The label of a Schedule that only runs whenever State<S> exits AND enters the provided exited and entered states.
State
A finite-state machine whose transitions have associated schedules (OnEnter(state) and OnExit(state)).
StateScoped
Entities marked with this component will be removed when the world’s state of the matching type no longer matches the supplied value.
StateTransition
Runs state transitions.
StateTransitionEvent
Event sent when any state transition of S happens. This includes identity transitions, where exited and entered have the same value.
TransitionSchedules
System set that runs transition schedule(s) for state S.

AppExtStates
State installation methods for App and SubApp.
ComputedStates
A state whose value is automatically computed based on the values of other States.
StateSet
A States type or tuple of types which implement States.
States
Types that can define world-wide states in a finite-state machine.
SubStates
A sub-state is a state that exists only when the source state meet certain conditions, but unlike ComputedStates - while they exist they can be manually modified.

in_state
Generates a Condition-satisfying closure that returns true if the state machine is currently in state.
last_transition
Returns the latest state transition event of type S, if any are available.
state_changed
A Condition-satisfying system that returns true if the state machine changed state.
state_exists
A Condition-satisfying system that returns true if the state machine exists.
