class: StateMachine

[16:7] extends: FxObj

Wraps FXGL's StateMachine (com.almasb.fxgl.core.fsm.StateMachine), a generic FSM container with a single parent state plus a queue of optional substates. Pair with the State wrapper (or any AussomState-implementing AJO) to drive gameplay phases, AI, menu transitions.

Methods

StateMachine (object InitialState)

Creates a new StateMachine with the given initial state.

@p InitialState is a State wrapper (or AJO implementing State).

getParentState ()

Returns the current parent state as an AJO.

getCurrentState ()

Returns the current state (substate if any, else parent).

getActiveStates ()

Returns the active states as an AussomJavaObject around a CopyOnWriteArrayList.

isInHierarchy (object StateObj)

Returns true when State is in the parent-or-substate hierarchy.

changeState (object NewState)

Transitions to the new state. If newState.isSubState the state is pushed; otherwise it replaces the parent state.

popSubState ()

Pops the topmost substate. Returns true when a substate was popped, false when no substate was active.

runOnActiveStates (callback Action)

Calls Action(state) for every currently-active state.

@p Action is a callback (stateAjo) -> void.
