}

Specifies how distance between effect source and listener attenuates effect.

They are based on OpenAL Specification (chapter 3.4), but the best way to see how they differ is to run ff_pos example.

Make sure that all parameters are ≥ 0. Additionally Linear and LinearClamped models don’t like if ref_distance == max_distance while others would prefer ref_distance > 0.

Trait Implementations

impl Clone for DistanceModel

fn clone(&self) -> DistanceModel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DistanceModel

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

Formats the value using the given formatter.

impl Default for DistanceModel

fn default() -> DistanceModel

Returns the “default value” for a type.

impl PartialEq for DistanceModel

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

This method tests for self and other values to be equal, and is used by ==.

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

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