Struct Shown

The terrain shown on every tile of a scene’s view and of the ring of tiles just outside it.

Implementations

impl Shown

pub fn of<U>(scene: &MapScene<U>) -> Self

What scene shows: each tile’s terrain, or what a spell being aimed would turn it into; a tile off the map (or one the scene doesn’t say) as the nearest tile that has terrain.

pub fn at(&self, dx: i32, dy: i32) -> Option<TerrainId>

The terrain shown on the tile dx right of and dy below the view’s first: a tile of the view or of the ring round it. None further out, or when no tile has terrain.

pub fn corners(&self, i: i32, j: i32) -> [Option<TerrainId>; 4]

The four tiles that meet at the top-left corner of the tile i right of and j below the view’s first: the ones up and left of the point, up and right, down and left, down and right.

pub fn sides(&self, dx: i32, dy: i32) -> [Option<TerrainId>; 4]

The four neighbours of the tile dx right of and dy below the view’s first: up, right, down, left.
