Trait rltk::Algorithm2D

pub trait Algorithm2D: BaseMap {
    fn point2d_to_index(&self, pt: Point) -> usize { ... }
    fn index_to_point2d(&self, idx: usize) -> Point { ... }
    fn dimensions(&self) -> Point { ... }
    fn in_bounds(&self, pos: Point) -> bool { ... }
}

Implement these for handling conversion to/from 2D coordinates (they are separate, because you might want Dwarf Fortress style 3D!)

Provided methods

fn point2d_to_index(&self, pt: Point) -> usize

Convert a Point (x/y) to an array index. Defaults to an index based on an array strided X first.

fn index_to_point2d(&self, idx: usize) -> Point

Convert an array index to a point. Defaults to an index based on an array strided X first.

fn dimensions(&self) -> Point

Retrieve the map's dimensions. Made optional to reduce API breakage.

fn in_bounds(&self, pos: Point) -> bool
