Struct TileRegion

pub struct TileRegion {
    pub origin: Vector2<i32>,
    pub bounds: OptionTileRect,
}

A region of tiles to be filled from some source of tiles.

Fields

origin: Vector2<i32>

The position to put the (0,0) tile of the tile source. If origin is not within bounds then the (0,0) tile will not actually be used.

bounds: OptionTileRect

The area to fill.

Implementations

impl TileRegion

pub fn from_bounds_and_direction( bounds: OptionTileRect, direction: Vector2<i32>, ) -> Self

Construct a region with its origin in one of the four corners of the given bounds. The corner of the origin is based on the given direction.

pub fn from_points(origin: Vector2<i32>, end: Vector2<i32>) -> Self

Construct a region with bounds that contain origin and end.

pub fn with_bounds(self, bounds: OptionTileRect) -> Self

Copy the region and replace its bound.

pub fn deflate(self, dw: i32, dh: i32) -> Self

Reduce the size of bounds by deflating them by the given amounts.

pub fn iter(&self) -> impl Iterator<Item = (Vector2<i32>, Vector2<i32>)> + '_

Iterator over (target, source) pairs where target is the position to put the tile and source is the position to get the tile from within the tile source. Every position within bounds will appear once as the target. If origin is within bounds, then (origin, (0,0)) will be produced by the iterator.

Trait Implementations

impl Debug for TileRegion

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

Formats the value using the given formatter.

impl Default for TileRegion

fn default() -> TileRegion

Returns the “default value” for a type.
