TGrid

trait TGrid

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.

@inline

The bottom, lowest or minimum Side Row of this TileGrid. The r value, the row number value.

@inline

The number of Rows of Sides.

The line segments LineSegs for the sides of the tiles.

Foreachs over each Row of Sides. Users will not normally need to use this method directly.

This gives the all tile grid lines in a single colour and line width.

@inline

The top, highest or maximum Side Row of this TileGrid. The r value, the row number.

Value members

Abstract methods

The bottom or lowest tile centre row, r coordinate.

The TileCenOrSide coordinate centre of this tile grid.

Foreach tile centre coordinate. A less strongly typed method than the foreach's in the sub traits.

Height of the tile grid from furthest tile edge or vertex to furthest tile edge or vertex.

The minimum or lowest tile centre column c coordinate in the whole tile grid. This is called c rather than x because in hex grids HGrids there is not a 1 to 1 ratio from column coordinate to the x value in a Pt2.

Number of rows of tile centres. This will be different to the number of rows of sides and and will be different to the number of rows of vertices for HexGrids.

The total number of tile centres in this tile Grid.

the Maximum or highest tile centre column c coordinate in the whole tile grid. This is called c rather than x because in hex grids HGrids there is not a 1 to 1 ratio from column coordinate to the x value in a Pt2.

The top of highest tile centre row, r coordinate.

Width of the tile Grid from furthest tile edge to furthest tile edge.

@inline

The centre of this grid in the y axis. For SqGrids this will be equal to the cCen Int value, but this is not the case for HGrids.

the ratio of r => y, when translating from TCoord tile grid coordinates to Pt2 and Vec2s.

Concrete methods

The centre of the hex grid in terms of c column coordinates.

The centre point as a Vec2. Not sure why this id implemented here.

flatMaps over each row number.

foldLefts over each row number.

Foreach grid Row y coordinate.

maps over each row number.

@inline

The number of Rows of vertices.

The centre of the hex grid in terms of r row coordinates.

Gives the text graphics for the row and column of each tile centre.

@inline

The bottom or lowest tile side row, r coordinate.

@inline

The top of highest tile side row, r coordinate.

@inline

The centre of this grid in the X axis. this will be equal to the cCen Int value.
