Adds two hexagons.

Gets the corners of the hexagon for the given layout, starting at the E vertex and proceeding in a CCW order.

Returns the list of hexagons that are visible from a given hexagon.

Determines if a given hexagon is visible from another hexagon, taking into consideration a set of blocking hexagons.

Returns the slice of hexagons that exist on a line that goes from hexagon a to hexagon b.

Returns the neighbor hexagon at a certain direction.

Returns the set of hexagons around a certain center for a given radius.

Returns the set of hexagons that form a rectangle with the specified width and height.

Scales an hexagon by a k factor.

Subtracts two hexagons.

HexToPixel returns the center pixel for a given hexagon an a certain layout.

PixelToHex returns the corresponding hexagon axial coordinates for a given pixel on a certain layout.

Hex describes a regular hexagon with Cube Coordinates (although the S coordinate is computed on the constructor) It's also easy to reference them as axial (trapezoidal coordinates): - R represents the vertical axis - Q the diagonal one - S can be ignored http://www.redblobgames.com/grids/hexagons/#coordinates/ _ _ / \ _ _ /(0,-1) \ _ _ / \ -R / \ /(-1,0) \ _ _ /(1,-1) \ \ -Q / \ / \ _ _ / (0,0) \ _ _ / / \ / \ /(-1,1) \ _ _ / (1,0) \ \ / \ +Q / \ _ _ / (0,1) \ _ _ / \ +R / \ _ _ / */.
