Module bevy_state::state

Provides definitions for the basic traits required by the state system

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)).
• 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.

Enums

• NextState
  The next state of State<S>.

Traits

• ComputedStates
  A state whose value is automatically computed based on the values of other States.
• FreelyMutableState
  This trait allows a state to be mutated directly using the NextState<S> resource.
• 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.

Functions

• last_transition
  Returns the latest state transition event of type S, if any are available.
• setup_state_transitions_in_world
  Sets up the schedules and systems for handling state transitions within a World.
