• updated extensions package to version 1.1

Version 1.9

In this version, we

• added custom shapes for all basic, non-polar grids in the editor
• slightly changed the design of LayeredGrid and LayeredPoint to make them more re-usable and robust
• fixed the position of gizmo labels for polar grids
• fixed a bug that caused null pointer exceptions in interactive grids with null cells
• fixed a bug with cell dimensions in hex grid builders that caused bugs when used with non-regular hexagons
• fixed a bug that caused editor code to be called in builds
• fixed a bug with Pointy hex shapes in the editor(fat and thin rectangles were swapped)
• removed the ToolTip and Description attributes (which implemented built-in functionality)
• made many documentation improvements

Version 1.8

In this version, we

• added grid builders that allows you to build grids in the editors, including the classes for supporting them, including
  • grid builder classes and their editors
  • classes for implementing custom maps and shapes that can be used with builders
  • classes that allows implementation of grid behaviours
  • cells and their editors
• added LineGrid and related classes for making 1D grids
• added ArchimedeanSpiralMap for use with a LineGrid to map cells in a spiral
• added LayeredGrid and related classes for making 3D grids made from layers of 2D grids
• added GenericSplicedGrids and related classes for making arbitrary semi-regular grids
• added PointListMap that maps a sequence of LinePoints to an arbitrary set of world points
• added VoronoiMap for mapping 2D space to an arbitrary point set
• added IGridToWorldMap, an interface for one-way maps that can be used by maps that does the inverse mapping automatically
• added method GetNeighborHood for RectGrid that returns a square region of points around a given point
• added method Stretch to map building to make it easy to get a grid stretched over a rectangle
• added class PoissonDisk for generating a PoissonDisk sample of points
• added constructors to InspectableVectorPoint and InspectableSplicedVectorPoint that takes other points as parameters
• added ToString methods to InspectableVectorPoint and InspectableSplicedVectorPoint
• made GetLongestConnected Obsolete (use GetLongestConnectedLine instead)
• removed ToString and GetHashCode from IGridPoint interface (these are redundant)
• made AnimatedMap also work with EditorApplication.timeSinceStartup
• fixed a bug with the edge grids of tri grids
• renamed “SuperRectGrid” to “NestedRectGrid”
• made enhancements to make Grids workbetteroniOS, including
  • rewriting certain methods to avoid problems with deep generics
  • adding more compiler hints for built-in cells

Version 1.7

In this update, we

• added Mod, Div and Mul methods for all uniform grid points.
• added Dot and PerpDot methods for all uniform grid points.
• added consistent coloring functions for all built-in grid points.
• added spiral iterator for hex grids.
• added some LINQ-like methods for grids, as well as GetValue and SetValue methods to make LINQ constructions easier to write.
• removed Equals from the declaration of IGridPoint. It is unnecessary, but more importantly caused unwanted boxing of points.
• added wrapped versions of Rectangular, Diamond, Hexagonal and Triangular Grids. Use the static WrappedX functions to use them.
• added a polar maps for Rectangular and Hex Grids that can be used with wrapped RectGrids and HexGrids to make polar grids.
• added some shapes for the Cairo grid.
• added a version of AStar that lets you specify the cost, not just the heuristic cost.
• fixed a bug with vertex and edge grids that plagued rectangular and diamond grids.
• fixed a bug with the canonical positions for hex-point shapes.
• simplified the underlying storage mechanism; this makes it easier to construct grids from scratch. It also had the result of default shapes changing from ragged rectangles to parallelograms (rect grids’ default shape remains a rectangle).
• changed some of the shape functions to make it more intuitive “where” a shape will be in relation to the origin.
• Made static helper functions in the Op classes that were accidentally exposed private. The public geometric functions provided by points should be used instead.
• improved the AStar algorithm’s run speed and its garbage generation.
• removed VectorPoint as implementation base for uniform points, thereby making them slightly faster.
• made many improvements to the documentation.

We also restructured the examples to make it easier to work through them in sequence.

Version 1.6

This is a maintenance update. We

• made the library more robust for AOT compilation by using safe containers and comparers, and providing hints for the compiler
• fixed the neighbor directions for DiamondGrids
• added the experimental SuperRectGrid class, a grid of grids
• added more point arithmetic for RectPoint
• added a safe implementation of IList for points
• removed most dependencies of List from the library interface, replacing most instances with IEnumerator, or IList in some instances.

This version also contains a new example of SuperRectGrid.

Version 1.5

We updated the documentation, added a few new examples for rectangular grids, and fixed two bugs:

• a bug with hex maps causing malfunction when the hex cells are not regular
• a spelling mistake with some enums containing the word North.

Version 1.4

We updated this guide, and re-organised the library slightly.

Version 1.3

This version contains mostly bugfixes and more examples. We

• added geometry calculations for hex points
• fixed wrong spelling of some methods that contains the word Middle – old methods have been made obsolete, so this change should not break your code
• fixed a bug in one of the 3D to 2D extension methods provided for Transform
• made lots of small code quality improvements under the hood (including a few optimisations).

There are three new examples that show how colourings work, how to use Grids in 3D games, and how Grids handles a very large hex grid.

Version 1.2

In this version we start adding technology that makes it easier to build your own grids. We

• added the PolygonMap class
• added CairoGrid, CairoPoint and CairoMap classes

There are also two new examples using the CairoGrids.

Version 1.1

This version contains mostly bug-fixes and a few small additions. We

• added grouping for shape building
• added symmetric difference for shape building
• added more parallelograms for triangular grids
• changed the diamond grid / point coordinate system to be more intuitive
• fixed a bug with hexagonal shapes for triangular grids
• fixed a bug with composite shape building
• fixed a bug with vertex and edge grids.

There are also two new examples, and we improved some of the existing examples slightly.
