Struct GridCone

pub struct GridCone {
    pub pos: IVec2,
    pub angle_dir_rad: f32,
    pub angle_arc_rad: f32,
    pub range: usize,
}

A cone/triangle of points on a 2d grid.

Fields

pos: IVec2

angle_dir_rad: f32

Angle of the cone in radians

angle_arc_rad: f32

Arc of the cone in radians

range: usize

Implementations

impl GridCone

pub fn new(xy: impl GridPoint, dir_deg: f32, arc_deg: f32, range: usize) -> Self

Create a new GridCone from angles represented in degrees.

Note an angle of 0. points to the right, and an angle of 90. points straight up (angle increases counter-clockwise).

pub fn origin(dir_deg: f32, size_deg: f32, range: usize) -> Self

Create a cone with it’s position set to [0,0]

pub fn corners(&self) -> [IVec2; 3]

Retrieve the 3 grid positions of the corners of the cone

The first point is the position of the cone, and the next two points are the two corners making up the cone triangle

Trait Implementations

impl Clone for GridCone

fn clone(&self) -> GridCone

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GridCone

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for GridCone

fn default() -> GridCone

Returns the “default value” for a type.

impl IntoIterator for GridCone

type Item = IVec2

The type of the elements being iterated over.

type IntoIter = GridConeIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for GridCone

fn eq(&self, other: &GridCone) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
