Struct bevy::audio::SpatialListener
pub struct SpatialListener {
pub left_ear_offset: Vec3,
pub right_ear_offset: Vec3,
}
Expand description
Settings for the listener for spatial audio sources.
This must be accompanied by Transform
and GlobalTransform
.
Only one entity with a SpatialListener
should be present at any given time.
Fields§
§left_ear_offset: Vec3
Left ear position relative to the GlobalTransform
.
right_ear_offset: Vec3
Right ear position relative to the GlobalTransform
.
Implementations§
§impl SpatialListener
impl SpatialListener
pub fn new(gap: f32) -> SpatialListener
pub fn new(gap: f32) -> SpatialListener
Creates a new SpatialListener
component.
gap
is the distance between the left and right “ears” of the listener. Ears are
positioned on the x axis.
