Struct ButtonSettings

pub struct ButtonSettings { /* private fields */ }

Manages settings for gamepad buttons.

It is used inside GamepadSettings to define the threshold for a GamepadButton to be considered pressed or released. A button is considered pressed if the press_threshold value is surpassed and released if the release_threshold value is undercut.

Allowed values: 0.0 <= ``release_threshold`` <= ``press_threshold`` <= 1.0

Implementations

impl ButtonSettings

pub fn new( press_threshold: f32, release_threshold: f32, ) -> Result<ButtonSettings, ButtonSettingsError>

Creates a new ButtonSettings instance.

Parameters

• press_threshold is the button input value above which the button is considered pressed.
• release_threshold is the button input value below which the button is considered released.

Restrictions:

• 0.0 <= ``release_threshold`` <= ``press_threshold`` <= 1.0

Errors

If the restrictions are not met, returns one of GamepadSettingsError::ButtonReleaseThresholdOutOfRange, GamepadSettingsError::ButtonPressThresholdOutOfRange, or GamepadSettingsError::ButtonReleaseThresholdGreaterThanPressThreshold.

pub fn is_pressed(&self, value: f32) -> bool

Returns true if the button is pressed.

A button is considered pressed if the value passed is greater than or equal to the press threshold.

pub fn is_released(&self, value: f32) -> bool

Returns true if the button is released.

A button is considered released if the value passed is lower than or equal to the release threshold.

pub fn press_threshold(&self) -> f32

Get the button input threshold above which the button is considered pressed.

pub fn try_set_press_threshold( &mut self, value: f32, ) -> Result<(), ButtonSettingsError>

Try to set the button input threshold above which the button is considered pressed.

Errors

If the value passed is outside the range [release threshold..=1.0], returns either GamepadSettingsError::ButtonPressThresholdOutOfRange or GamepadSettingsError::ButtonReleaseThresholdGreaterThanPressThreshold.

pub fn set_press_threshold(&mut self, value: f32) -> f32

Try to set the button input threshold above which the button is considered pressed. If the value passed is outside the range [release threshold..=1.0], the value will not be changed.

Returns the new value of the press threshold.

pub fn release_threshold(&self) -> f32

Get the button input threshold below which the button is considered released.

pub fn try_set_release_threshold( &mut self, value: f32, ) -> Result<(), ButtonSettingsError>

Try to set the button input threshold below which the button is considered released.

Errors

If the value passed is outside the range [0.0..=press threshold], returns ButtonSettingsError::ReleaseThresholdOutOfRange or ButtonSettingsError::ReleaseThresholdGreaterThanPressThreshold.

pub fn set_release_threshold(&mut self, value: f32) -> f32

Try to set the button input threshold below which the button is considered released. If the value passed is outside the range [0.0..=press threshold], the value will not be changed.

Returns the new value of the release threshold.
