BooleanEvent

class wpilib.event.BooleanEvent(loop: wpilib.event._event.EventLoop, condition: Callable[[], bool])

Bases: pybind11_object

This class provides an easy way to link actions to inputs. Each object represents a boolean condition to which callback actions can be bound using IfHigh().

These events can easily be composed using factories such as {@link #operator!}, {@link #operator||}, {@link #operator&&} etc.

To get an event that activates only when this one changes, see {@link #Falling()} and Rising().

Creates a new event with the given condition determining whether it is active.

Parameters:

loop – the loop that polls this event
condition – returns whether or not the event should be active

castTo(ctor: Callable) → object

A method to “downcast” a BooleanEvent instance to a subclass (for example, to a command-based version of this class).

Parameters:: ctor – a method reference to the constructor of the subclass that accepts the loop as the first parameter and the condition/signal as the second.
Returns:: an instance of the subclass.

debounce(debounceTime: wpimath.units.seconds, type: wpimath.filter._filter.Debouncer.DebounceType = <DebounceType.kRising: 0>) → wpilib.event._event.BooleanEvent

Creates a new debounced event from this event - it will become active when this event has been active for longer than the specified period.

Parameters:

debounceTime – The debounce period.
type – The debounce type.

Returns:

The debounced event.

falling() → wpilib.event._event.BooleanEvent

Get a new event that triggers only when this one newly changes to false.

Returns:: a new event representing when this one newly changes to false.

getAsBoolean() → bool

Check whether this event is active or not as of the last loop poll.

Returns:: true if active, false if not active. If the event was never polled, it returns the state at event construction.

ifHigh(action: Callable[[], None]) → None

Bind an action to this event.

Parameters:: action – the action to run if this event is active.

rising() → wpilib.event._event.BooleanEvent

Get a new event that events only when this one newly changes to true.

Returns:: a new event representing when this one newly changes to true.
