Class TileRotationBuilder

Builds a TileRotation. This class lets you specify some transformations between tiles via rotation and reflection. It then infers the full set of rotations possible, and informs you if there are contradictions.

As an example of inference, if a square tile 1 transforms to tile 2 when rotated clockwise, and tile 2 transforms to itself when reflected in the x-axis, then we can infer that tile 1 must transform to tile 1 when reflected in the y-axis.

Syntax

public class TileRotationBuilder

Constructors

TileRotationBuilder(RotationGroup, TileRotationTreatment)

Declaration

public TileRotationBuilder(RotationGroup rotationGroup, TileRotationTreatment defaultTreatment = TileRotationTreatment.Unchanged)

Parameters

Type	Name	Description
RotationGroup	rotationGroup
TileRotationTreatment	defaultTreatment

TileRotationBuilder(int, bool, TileRotationTreatment)

Declaration

public TileRotationBuilder(int rotationalSymmetry, bool reflectionalSymmetry, TileRotationTreatment defaultTreatment = TileRotationTreatment.Unchanged)

Parameters

Type	Name	Description
int	rotationalSymmetry
bool	reflectionalSymmetry
TileRotationTreatment	defaultTreatment

Properties

RotationGroup

Declaration

public RotationGroup RotationGroup { get; }

Property Value

Type	Description
RotationGroup

Methods

Add(Tile, Rotation, Tile)

Indicates that if you reflect then rotate clockwise the src tile as indicated, then you get the dest tile.

Declaration

public void Add(Tile src, Rotation rotation, Tile dest)

Parameters

Type	Name	Description
Tile	src
Rotation	rotation
Tile	dest

AddSymmetry(Tile, TileSymmetry)

Declares that a tile is symetric, and therefore transforms to iteself. This is a shorthand for calling Add(tile,..., tile) for specific rotations.

Declaration

public void AddSymmetry(Tile tile, TileSymmetry ts)

Parameters

Type	Name	Description
Tile	tile
TileSymmetry	ts

Build()

Extracts the full set of rotations

Declaration

public TileRotation Build()

Returns

Type	Description
TileRotation

SetTreatment(Tile, TileRotationTreatment)

Declaration

public void SetTreatment(Tile tile, TileRotationTreatment treatment)

Parameters

Type	Name	Description
Tile	tile
TileRotationTreatment	treatment
