Enum DynShape 

pub enum DynShape<T> {
    Circle(Circle<T>),
    Triangle(Triangle<T>),
    Rect(Rect<T>),
    Quad(Quad<T>),
    Polygon(Polygon<T>),
}

A circle, triangle, rect, quad, or polygon.

This itself implements Shape<T> and defers to each variant’s implementation of the trait’s methods.

This is convenient when you want lists of shapes that can be one of any of the variants, rather than all being the same. For example, colliders for entities in a core engine.

Variants

Circle(Circle<T>)

Triangle(Triangle<T>)

Rect(Rect<T>)

Quad(Quad<T>)

Polygon(Polygon<T>)

Implementations

impl<T: Float> DynShape<T>

pub fn overlaps(&self, other: &Self) -> bool

Returns true if this shape overlaps the other.

pub fn extract_from(&self, other: &Self) -> Option<Vec2<T>>

If this shape overlaps the other, returns a push-out vector that can be used to translate it so they no longer overlap.

pub fn hull_points(&self, circle_seg_len: T, plot: impl FnMut(Vec2<T>))

Plot the vertices of the shape. For polygons, it will be the vertices of the polygon, and for circles it will be CAP points distributed evenly along the circle’s radius.

pub fn hull_points_n(&self, circle_count: T, plot: impl FnMut(Vec2<T>))

Plot the vertices of the shape.

pub fn hull_edges(&self, circle_seg_len: T, plot: impl FnMut(Line<T>))

Plot the edges of the shape. For polygons, it will be the edges of the polygon, and for circles it will be CAP edgds distributed evenly along the circle’s radius.

pub fn hull_edges_n(&self, circle_count: T, plot: impl FnMut(Line<T>))

Plot the edges of the shape. For polygons, it will be the edges of the polygon, and for circles it will be CAP edgds distributed evenly along the circle’s radius.

pub fn transform_into( &self, into: &mut Self, circle_out: CircleOut<T>, rect_out: RectOut, f: impl FnMut(Vec2<T>) -> Vec2<T>, )
