Allure of the Stars

Allure of the Stars6 is a near-future Sci-Fi roguelike2 and tactical squad game. Try out the browser version of the LambdaHack sample game at [http://allureofthestars.com/play](http://allureofthestars.com/play)! (It runs fastest on Chrome. Keyboard commands and savefiles are supported only on recent enough versions of browsers. Mouse should work everywhere.)

Please see the changelog file for recent improvements and the issue tracker for short-term plans. Long term goals are high replayability and auto-balancing through procedural content generation and persistent content modification based on player behaviour. Contributions are welcome.

The game is written in Haskell1 using the LambdaHack 10 roguelike game engine. Long-term goals of the project are high replayability and auto-balancing through procedural content generation and persistent content modification based on player behaviour.

Game installation from binary archives

The game runs rather slowly in the browser (fastest on Chrome) and you are limited to only one font, though it's scalable. Keyboard input and saving game progress requires recent enough version of a browser (but mouse input is enough to play the game). Also, savefiles are prone to corruption on the browser, e.g., when it's closed while the game is still saving progress (which takes a long time). Hence, after trying out the game, you may prefer to use a native binary for your architecture, if it exists.

Pre-compiled game binaries for some platforms are available through the release page11 and from the Nix Packages Collection12 (Linux) and AppVeyor (Windows 32bit17 and Windows 64bit18; note that these no longer work on Windows XP, since Cygwin and MSYS2 dropped support for XP; they may also be broken in other ways; feedback and help appreciated). To use a pre-compiled binary archive, unpack it and run the executable in the unpacked directory.

On Linux, make sure you have the SDL2 libraries suite installed on your system (e.g., libsdl2, libsdl2-ttf). For Windows, the SDL2 and all other needed libraries are already contained in the game's binary archive.

Screen and keyboard configuration

The game UI can be configured via a config file. A file with the default settings, the same that is built into the binary, is in GameDefinition/config.ui.default. When the game is run for the first time, the file is copied to the default user data folder, which is ~/.Allure/ on Linux, C:\Users\<username>\AppData\Roaming\Allure\ (or C:\Documents And Settings\user\Application Data\Allure\ or something else altogether) on Windows, and in RMB menu, under Inspect/Application/Local Storage when run inside the Chrome browser.

Screen font can be changed by editing the config file in the user data folder. For a small game window, the highly optimized bitmap fonts 16x16x.fon, 8x8x.fon and 8x8xb.fon are the best, but for larger window sizes or if you require international characters (e.g. to give custom names to player characters), a modern scalable font supplied with the game is the only option. The game window automatically scales according to the specified font size. Display on SDL2 and in the browser is superior to all the other frontends, due to custom square font and less intrusive ways of highlighting interesting squares.

If you don't have a numeric keypad, you can use mouse or laptop keys (uk8o79jl) for movement or you can enable the Vi keys (aka roguelike keys) in the config file. If numeric keypad doesn't work, toggling the Num Lock key sometimes helps. If running with the Shift key and keypad keys doesn't work, try Control key instead. The game is fully playable with mouse only, as well as with keyboard only, but the most efficient combination for some players is mouse for go-to, inspecting, and aiming at distant positions and keyboard for everything else.

If you are using a terminal frontend, numeric keypad may not work correctly depending on versions of the libraries, terminfo and terminal emulators. Toggling the Num Lock key may help. The curses frontend is not fully supported due to the limitations of the curses library. With the vty frontend started in an xterm, Control-keypad keys for running seem to work OK, but on rxvt they do not. The commands that require pressing Control and Shift together won't work either, but fortunately they are not crucial to gameplay.

Compilation from source

If you want to compile native binaries from the source code, use Cabal (already a part of your OS distribution, or available within The Haskell Platform7), which also takes care of all the dependencies.

The recommended frontend is based on SDL2, so you need the SDL2 libraries for your OS. On Linux, remember to install the -dev versions as well, e.g., libsdl2-dev and libsdl2-ttf-dev on Ubuntu Linux 16.04. (Compilation to Javascript for the browser is more complicated and requires the ghcjs15 compiler and optionally the Google Closure Compiler16 as well. See the Makefile for more details.)

The latest official version of the game can be downloaded, compiled for SDL2 and installed automatically by Cabal from Hackage3 as follows

cabal update
cabal install Allure --force-reinstalls

For a newer version, install a matching LambdaHack library snapshot from a development branch, download the game source from github5 and run cabal install from the main directory.

Testing and debugging

The Makefile contains many sample test commands. Numerous tests that use the screensaver game modes (AI vs. AI) and the teletype frontend are gathered in make test. Of these, travis runs test-travis on each push to github. Test commands with prefix frontend start AI vs. AI games with the standard, user-friendly frontend.

Run Allure --help to see a brief description of all debug options. Of these, --sniffIn and --sniffOut are very useful (though verbose and initially cryptic), for monitoring the traffic between clients and the server. Some options in the config file may prove useful too, though they mostly overlap with commandline options (and will be totally merged at some point).
