Function pathfinder::tools::plot

pub fn plot(
    coordinates1: Coordinate,
    coordinates2: Coordinate
) -> Vec<Coordinate>

Implemented according to https://en.wikipedia.org/wiki/Bresenham%27s_line_algorithm

Plots the pixels between two coordinate points. Checks so that the applied adjustments stay within a u8.

Examples

First we create a simple path between two coordinates.

use pathfinder::{tools, Coordinate};
let a = Coordinate::new(0, 0);
let b = Coordinate::new(1, 1);
let path = tools::plot(a, b);

To confirm the small path created. Larger paths are more difficult to manually test.

let correct_path = vec![
    Coordinate::new(0, 0),
    Coordinate::new(1, 0),
    Coordinate::new(1, 1),
];
assert_eq!(path, correct_path);
