Struct Space2d 

pub struct Space2d {
    pub width: f32,
    pub min_distance: f32,
    pub max_distance: f32,
    pub model: Distance,
}

How a 2D position relative to the listener becomes a pan and a gain.

The horizontal offset x pans the sound with the mixer’s constant-power law: pan = x / width, limited to -1..=1, so a sound width units to the right is fully right. The distance d = √(x² + y²) sets a gain of 1 up to min_distance and 0 from max_distance; in between, Distance::Linear falls in a straight line and Distance::Inverse follows min/d, shifted and scaled so it reaches 0 at the maximum instead of jumping there.

Fields

width: f32

Horizontal offset at which a sound is fully to one side. Default 1.

min_distance: f32

Distance up to which a sound plays at full gain. Default 1.

max_distance: f32

Distance from which a sound is silent. Default 10.

model: Distance
