What is RogueSharp?

RogueSharp is a free library written in C# to help roguelike developers get a head start on their game. RogueSharp provides many utility functions for dealing with map generation, field-of-view calculations, path finding, random number generation and more.

It is loosely based on the popular libtcod or "Doryen Library" though not all features overlap.

Getting Started

  1. Visit the RogueSharp Blog for tips and tutorials.
  2. The quickest way to add RogueSharp to your project is by using the RogueSharp nuget package.
  3. If building the assembly yourself, the solution file "RogueSharp.sln" contains the main library and unit tests. This should be all you need.
  4. The solution file "RogueSharpPerformanceTests.sln" contains a wrapper for libtcod and was only used to test performance of similar functions between RogueSharp and libtcod
  5. The solution file "RogueSharpDocumentation.sln" requires Sandcastle Help File Builder to be installed. It can be used to generate documentation for the library from the XML comments on public methods.

Creating a Map

Most interactions with RogueSharp is based around the concept of a Map which is a rectangular grid of Cells.

Each Cell in a Map has the following properties:

  • IsTransparent: true if visibility extends through the Cell.
  • IsWalkable: true if a the Cell may be traversed by the player
  • IsExplored: true if the player has ever had line-of-sight to the Cell
  • IsInFov: true if the Cell is currently in the player's field-of-view

To instantiate a new Map you can use its constructor which takes a width and height and will create a new map of those dimensions with the properties of all Cells set to false.

Usage

IMap boringMapOfSolidStone = new Map( 5, 3 );
Console.WriteLine( boringMapOfSolidStone.ToString() );

Notice that the ToString() operator is overridden on the Map class to provide a simple visual representation of the map. An optional bool parameter can be provided to ToString() to indicate if you want to use the field-of-view or not. If the parameter is not given it defaults to false.

The symbols used are as follows:

  • %: Cell is not in field-of-view
  • .: Cell is transparent, walkable, and in field-of-view
  • s: Cell is walkable and in field-of-view (but not transparent)
  • o: Cell is transparent and in field-of-view (but not walkable)
  • #: Cell is in field-of-view (but not transparent or walkable)

A more interesting way to create a map is to use the Map class's static method Create which takes an IMapCreationStrategy. Some simple classes implementing IMapCreationStrategy are provided with RogueSharp but this is easily extended by creating your own class that implements the strategy.

Usage

IMapCreationStrategy<Map> mapCreationStrategy = new RandomRoomsMapCreationStrategy<Map>( 17, 10, 30, 5, 3 )
IMap somewhatInterestingMap = Map.Create( mapCreationStrategy );
Console.WriteLine( somewhatInterestingMap.ToString() );
