    pub state: u16,
    pub previous: u16,
}

Fields

state: u16

previous: u16

Implementations

impl DPad

pub fn new() -> Self

pub fn copy_current_to_previous_state(&mut self)

Must be called once per frame, prior to setting any value for the current state.

pub fn is_down(&self, button: Button) -> bool

Whether the given button is currentl down.

pub fn is_up(&self, button: Button) -> bool

Whether the given button is currentl up.

pub fn is_just_pressed(&self, button: Button) -> bool

Whether the given button has just been pressed this frame. Requires [copy_current_to_previous_state] to have been called at the beginning of the frame

pub fn is_just_released(&self, button: Button) -> bool

Whether the given button has just been released this frame. Requires [copy_current_to_previous_state] to have been called at the beginning of the frame

pub fn set_state(&mut self, button: Button, value: bool)

Sets the bit for a particular button.

Trait Implementations

impl Clone for DPad

fn clone(&self) -> DPad

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DPad

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DPad

fn default() -> DPad

Returns the “default value” for a type.

impl PartialEq for DPad

fn eq(&self, other: &DPad) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
