Enum Shape2D 

pub enum Shape2D {
    Circle {
        radius: Fix128,
    },
    Polygon {
        vertices: Vec<Vec2Fix>,
    },
    Capsule {
        radius: Fix128,
        half_length: Fix128,
    },
    Edge {
        start: Vec2Fix,
        end: Vec2Fix,
    },
}

2D collision shape.

All shapes are defined in local space relative to the body’s center of mass.

Variants

Circle

Circle defined by its radius.

Fields

radius: Fix128

Radius of the circle.

Polygon

Convex polygon defined by vertices in CCW winding order.

Fields

vertices: Vec<Vec2Fix>

Vertices in counter-clockwise order. Must form a convex hull.

Capsule

Capsule defined by a radius and half-length along the local X axis.

Fields

radius: Fix128

Radius of the capsule’s hemicircles.

half_length: Fix128

Half of the segment length between hemicircle centers.

Edge

Line segment (edge) from start to end.

Zero thickness and two-sided: it collides with circles, capsules and polygons from either side, but not with other edges (two segments enclose no area, so parallel edges never overlap).

Fields

start: Vec2Fix

Start point in local space.

end: Vec2Fix

End point in local space.
