pub struct AxisSettings { /* private fields */ }
Expand description

Settings for a GamepadAxis.

It is used inside of the GamepadSettings to define the sensitivity range and threshold for an axis. Values that are higher than livezone_upperbound will be rounded up to 1.0. Values that are lower than livezone_lowerbound will be rounded down to -1.0. Values that are in-between deadzone_lowerbound and deadzone_upperbound will be rounded to 0.0. Otherwise, values will not be rounded.

The valid range is [-1.0, 1.0].

Implementations§

source§

impl AxisSettings

source

pub fn new( livezone_lowerbound: f32, deadzone_lowerbound: f32, deadzone_upperbound: f32, livezone_upperbound: f32, threshold: f32 ) -> Result<AxisSettings, AxisSettingsError>

Creates a new AxisSettings instance.

Arguments
  • livezone_lowerbound - the value below which inputs will be rounded down to -1.0.
  • deadzone_lowerbound - the value above which negative inputs will be rounded up to 0.0.
  • deadzone_upperbound - the value below which positive inputs will be rounded down to 0.0.
  • livezone_upperbound - the value above which inputs will be rounded up to 1.0.
  • threshold - the minimum value by which input must change before the change is registered.

Restrictions:

  • -1.0 <= livezone_lowerbound <= deadzone_lowerbound <= 0.0
  • 0.0 <= deadzone_upperbound <= livezone_upperbound <= 1.0
  • 0.0 <= threshold <= 2.0
Errors

Returns an AxisSettingsError if any restrictions on the zone values are not met. If the zone restrictions are met, but the threshold value restrictions are not met, returns AxisSettingsError::Threshold.
