Struct DPad8 

pub struct DPad8 {
    pub left: bool,
    pub right: bool,
    pub up: bool,
    pub down: bool,
}

8-directional DPad-like representation of the Pad.

Constructed with Pad::as_dpad8. Useful for simple games and ports. The middle of the pad is a “dead zone” pressing which will not activate any direction.

Implements all the same methods as DPad4.

Invariant: it’s not possible for opposite directions (left and right, or down and up) to be active at the same time. However, it’s possible for heighboring directions (like up and right) to be active at the same time if the player presses a diagonal.

For completeness, here is the full list of possible states:

• right
• right and up
• up
• left and up
• left
• left and down
• down
• right and down
• none

Fields

left: bool

right: bool

up: bool

down: bool

Implementations

impl DPad8

pub fn any(&self) -> bool

Check if any direction is pressed.

pub fn just_pressed(&self, old: &Self) -> Self

Given the old state, get directions that were not pressed but are pressed now.

pub fn just_released(&self, old: &Self) -> Self

Given the old state, get directions that were pressed but aren’t pressed now.

pub fn held(&self, old: &Self) -> Self

Given the old state, get directions that were pressed and are still pressed now.

Trait Implementations

impl Clone for DPad8

fn clone(&self) -> DPad8

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DPad8

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

Formats the value using the given formatter.

impl Default for DPad8

fn default() -> DPad8

Returns the “default value” for a type.

impl From<DPad4> for DPad8

fn from(value: DPad4) -> Self

Converts to this type from the input type.

impl From<Option<DPad8>> for DPad8

fn from(value: Option<DPad8>) -> Self

Converts to this type from the input type.

impl From<Pad> for DPad8

fn from(value: Pad) -> Self

Converts to this type from the input type.

impl Hash for DPad8

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DPad8

fn cmp(&self, other: &DPad8) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DPad8

fn eq(&self, other: &DPad8) -> 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.

impl PartialOrd for DPad8

fn partial_cmp(&self, other: &DPad8) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
