RectGrid

A grid of rectangular tiles. Wraps a 2D array to provide grid-based access to tiles.

struct RectGrid (

T

) if (

isArray2D!T

) {

alias TileType = typeof(_tiles[0][0]);

this(T tiles);

auto numCols();

auto numRows();

auto numTiles();

bool contains(RowCol coord);

auto ref tileAt(RowCol coord);

auto ref tilesAt(R coords);

auto allCoords();

auto allTiles();

int opApply(int delegate(ref TileType) fn);

int opApply(int delegate(RowCol, ref TileType) fn);

auto maskCoords(RowCol offset, in T mask);

auto maskTiles(RowCol offset, in T mask);

auto maskCoordsAround(RowCol center, in T mask);

auto maskTilesAround(RowCol center, in T mask);

auto adjacentTiles(RowCol coord, Diagonals diagonals = Diagonals.no);

}

Constructors

this this(T tiles): Construct a grid from a 2D tile array. See rectGrid for a constructor with type inference.

Members

Aliases

TileType alias TileType = typeof(_tiles[0][0]): The type used to represent a tile in this grid

Functions

adjacentTiles auto adjacentTiles(RowCol coord, Diagonals diagonals = Diagonals.no): Return all tiles adjacent to the tile at the given coord (not including the tile itself).
allCoords auto allCoords(): Get a range that iterates through every coordinate in the grid.
allTiles auto allTiles(): Get a range that iterates through every tile in the grid.
contains bool contains(RowCol coord): True if the grid coordinate is within the grid bounds.
maskCoords auto maskCoords(RowCol offset, in T mask): Same as maskTiles, but return coords instead of tiles.
maskCoordsAround auto maskCoordsAround(RowCol center, in T mask): Same as maskCoords, but centered.
maskTiles auto maskTiles(RowCol offset, in T mask): Select specific tiles from this slice based on a mask.
maskTilesAround auto maskTilesAround(RowCol center, in T mask): Same as maskTiles, but centered.
numCols auto numCols(): Number of columns along a grid's x axis.
numRows auto numRows(): Number of rows along a grid's y axis.
numTiles auto numTiles(): The total number of tiles in a grid.
opApply int opApply(int delegate(ref TileType) fn): Foreach over every tile in the grid. Supports ref.
opApply int opApply(int delegate(RowCol, ref TileType) fn): Foreach over every (coord,tile) pair in the grid. Supports ref.
tileAt auto ref tileAt(RowCol coord): Get the tile at a given position in the grid. The coord must be in bounds.
tilesAt auto ref tilesAt(R coords): Access tiles via a range of coords. Tiles are returned by ref.
