Struct EllipseColliderShape

pub struct EllipseColliderShape(pub Ellipse);

An ellipse shape that can be stored in a SharedShape for an ellipse Collider.

This wrapper is required to allow implementing the necessary traits from parry for Bevy’s Ellipse type.

Tuple Fields

0: Ellipse

Methods from Deref<Target = Ellipse>

pub fn eccentricity(&self) -> f32

Returns the eccentricity of the ellipse. It can be thought of as a measure of how “stretched” or elongated the ellipse is.

The value should be in the range [0, 1), where 0 represents a circle, and 1 represents a parabola.

pub fn focal_length(&self) -> f32

Get the focal length of the ellipse. This corresponds to the distance between one of the foci and the center of the ellipse.

The focal length of an ellipse is related to its eccentricity by eccentricity = focal_length / semi_major

pub fn semi_major(&self) -> f32

Returns the length of the semi-major axis. This corresponds to the longest radius of the ellipse.

pub fn semi_minor(&self) -> f32

Returns the length of the semi-minor axis. This corresponds to the shortest radius of the ellipse.
