Struct Curve 

pub struct Curve { /* private fields */ }

A curve with owned lists of path points and segment lengths.

Implementations

impl Curve

pub fn new( mode: GameMode, points: &[PathControlPoint], expected_len: Option<f64>, bufs: &mut CurveBuffers, ) -> Self

Create a new Curve.

pub fn path(&self) -> &[Pos]

Path points of the Curve.

pub fn lengths(&self) -> &[f64]

The Curve’s length at each path point.

pub fn position_at(&self, progress: f64) -> Pos

The interpolated position at the given progress.

pub fn progress_to_dist(&self, progress: f64) -> f64

Value between 0.0 and the curve’s distance, depending on the given progress between 0.0 and 1.0.

pub fn dist(&self) -> f64

The total distance of the Curve.

pub fn idx_of_dist(&self, d: f64) -> usize

The index into Curve::lengths to reach the distance d.

pub fn interpolate_vertices(&self, i: usize, d: f64) -> Pos

Interpolate the position between the i’th and i+1’th path position at distance d.

pub fn as_borrowed_curve(&self) -> BorrowedCurve<'_>

Cheaply transform Curve into BorrowedCurve.

Trait Implementations

impl Clone for Curve

fn clone(&self) -> Curve

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Curve

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

Formats the value using the given formatter.

impl PartialEq for Curve

fn eq(&self, other: &Curve) -> 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.
