A Hex tile centre hexG grid HGrid coordinate.

Companion object of HCen trait, contains HVert values for hex tile 0, 0. As well as apply method and Show implicit.

An array of hex tile or hex centre data. For efficiency the data is stored as a flat Array. No run time information distinguishes this from an ordinary linear sequence array of data. Whether in a game or a non game application the data of the grid tiles is likely to change much more frequently than the size, shape, structure of the grid. The compiler knows this is hex grid array and hence the data should be set and retrieved through the HGrid hex grid. So nearly all the methods take the HGrid as an implicit parameter.

Companion object for HCenArr, contains an apply factory method.

A Hex grid array class of Arrs.

An HCen hex tile centre grid Arr of ArrayBuffers corresponding to the centres of an HGrid hex tile grid.

Companion object for the hex (centres) grid Array of ArrayBuffer classes.

An immutable Arr of Opt Tile data for a specific hex tile grid HGrid. This is specialised for OptRef[A]. The tileGrid can map the HCen coordinate of the tile to the index of the Arr. Hence most methods take an implicit HGrid hex grid parameter.

Common trait for hex centre and hex side coordinate. The position of these coordinates is proportional, unlike the Hex vertices positions.

A row or a segment a row of Hex tiles in a grid. The start / left centre HexGrid coordinate and the number of tiles in the row..

An efficient array[Int] based collection for HCens hex grid centre coordinates.

A coordinate with in a Hex grid. It may be a Hex tile centre HCen, a HexSide HSide or Hex tile vertice HVert.

A 2d line upon a HexGrid defined by its start and end HGrid HCoords.

A grid of Hexs. The grid may be a regular rectangle of hexs or an irregular grid with variable length rows.

An irregular hex grid, where the rows have different lengths and irregular start row coordinates. This is backed by an Array[Int] The (0) value gives the number of tile centre HCen rows. The (1) value gives the rTileMin the bottom row coordinate. There are 2 more values for row. Each row from lowest to highest has two values length of the row in the number of tile centres HCens and the rTileMin coordinate for the row.

An irregular hex grid, where the rows have different lengths and irregular start row coordinates. This is backed by an Array[Int] The (0) value gives the number of tile centre HCen rows. The (1) value gives the rTileMin the bottom row coordinate. There are 2 more values for row. Each row from lowest to highest has two values length of the row in the number of tile centres HCens and the rTileMin coordinate for the row.

A Regular hex grid where the tile rows have the same length, except the tile rows where r %% 4 == 2 may differ in length by 1 from tile rows where r %% 4 == 0 rows.

Companion object for the HGridReg class. Contains an applr method that corrects the r and Y minimum and maximum values.

A Hex side coordinate in a Hex Grid. So Side 1 on its primary Hex tile goes from Vert 6 to 1 while it is Side 4 on its secondary Hex tile and goes from Vertex 4 to vertex 3 So Side 2 on its primary Hex tile goes from Vert 1 to 2 while it is Side 5 on its secondary Hex tile and goes from Vertex 5 to vertex 4 So Side 3 on its primary Hex tile goes from Vert 2 to 3 while it is Side 4 on its secondary Hex tile and goes from Vertex 6 to vertex 4

Companion object for the HSide class, provides an apply factory method that throws an exception for an invalid Hex side coordinate.

Boolean data corresponding to the sides of a hex grid, stored using an underlying Array[Boolean]. Thhese classes should be created, initalised and used using an [HGrid]] class. For convenience the HGrid is passed as an implicit parameter.

An efficient array[Int] based collection for HSides hex grid centre coordinates.

Companion object for HSides trait efficient array[Int] based collection for HSides hex grid centre coordinates, contains factory apply and uninitialised methods.

A step on a hex tile grid HGrid can take 6 values: upright right, downright, downleft, left and upleft.

A step downleft on a hex tile grid HGrid.

A step downright on a hex tile grid HGrid.

A step left on a hex tile grid HGrid.

A step right on a hex tile grid HGrid.

A step upleft on a hex tile grid HGrid.

A step upright on a hex tile grid HGrid.

A trait for HSteps. The purpose of the trait rather than a class is to allow the consumer to mix in their own traits. Its not clear whether this is useful in Scala 3 or its bettter to use union types with the HSteps class.

A hex tile vertex coordinate.

An array[Int] based collection for HVert.

Common trait for Hverts and PolygonHC

Hex centre coordinate and hex step.

A polygon with the vertices defined by hex tile corrdinates HCoords.

Companion object for the polygon whose vertices are defined by hex tile coordinates PolygonHC trait.

A Square tile centre square grid SqGrid coordinate.

An array of hex tile or hex centre data.

An Array of ArrayBuffers corresponding to (the centres of a) Hex tile Grid.

Companion object for the Hex (centres) grid Array of ArrayBuffer classes.

An immutable Arr of Opt Tile data for a specific square tile grid SqGrid. This is specialised for OptRef[A]. The tileGrid can map the SqCen coordinate of the tile to the index of the Arr. Hence most methods take an implicit SqGrid square grid parameter.

A square grid integer tile coordinate.

A grid of Squares. A regular rectangle of squares.

Companion object for the HGridReg class. Contains an applr method that corrects the r and Y minimum and maximum values.

A Square tile side square grid SqGrid coordinate.

A square tile step can take 8 values

A non-diagonal square tile Step can take 4 values.

An downward step / move / addition of one square tile in a square tile grid.

An upward of one square tile in a square tile grid.

A non-diagonal square tile Step can take 4 values.

An rightward step / move / addition of one square tile in a square tile grid. Increases the column coordinate by 2

An upward step / move addition of one square tile in a square tile grid. Increases the row coordinate by 2.

A Square tile vertex square grid SqGrid coordinate.

A coordinate in a tile grid TGrid. The row is the first field, the column is the second.

Companion object for TCoord trait will contain a Show[TCoord] implicit instance in Scala 3, but this produces an error in 2.13.5.

A TileGrid is a description of an abstract TileGrid. It contains no data for the elements of any particular TileGrid. The Data for TileGrids is stored in flat arrays. The TileGrid gives the dimensions of a tileGrid. It has methods to interpret the data in flat Arrays created for that TileGrid specification. It has methods to map the elements of an Array to the the 2 dimensional geometry of the Tile Grid. On its own a TileGrid can produce the outlines of the grid, coordinates vector positions and other pure mathematical data. Combined with a simple function it can for example produce a Chess board. Combined with a 64 length array it can produce a Chess board position. For anything but the most simple games, you will probably want multiple arrays to describe the game state. The terrain for example may remain invariant, so the terrain data does not need to be reproduced with every move.

A TileGrid is for use cases where the proportions of the Grid predetermine the proportions of the visual representation, as opposed to a use case where the proportions of the enclosing space are a factor in determining the proportions of the grid. For example the various grid layouts of the Stars on the American flag.

A tile step, move or addition, or no move.

The hex centre step values.

The square centre step values.
