Struct bevy::math::primitives::CircularSector

pub struct CircularSector {
    pub arc: Arc2d,
}

A primitive representing a circular sector: a pie slice of a circle.

The segment is positioned so that it always includes Vec2::Y and is vertically symmetrical. To orient the sector differently, apply a rotation. The sector is drawn with the center of its circle at the origin Vec2::ZERO.

Warning: Circular sectors with negative angle or radius, or with angle greater than an entire circle, are not officially supported. We recommend normalizing circular sectors to have an angle in [0, 2π].

Fields

arc: Arc2d

The arc defining the sector
