Allure of the Stars is a near-future Sci-Fi roguelike[2]

and tactical squad combat game. Binaries and the game manual

are available at the homepage[6]. You can also try the game out

in the browser at http://allureofthestars.com/play.

Not a single image in this game. You have to imagine everything

yourself, like with a book (a grown-up book, without pictures).

Once you learn to imagine things, though, you can keep exploring

and mastering the world and making up stories for a long time.



The game is written in Haskell[1] using the LambdaHack[10] roguelike

game engine.

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.

Please offer feedback to [email protected] or, preferably,

on any of the public forums.



Game installation from binary archives

--------------------------------------



The game runs rather slowly in the browser (fastest on Chrome) and you are

limited to the square font for all purposes, though it's scalable.

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 are available through the release page[11]

(and Linux dev versions from GitHub Actions[18] and Windows from AppVeyor[19]).

To use a pre-compiled binary archive, unpack it and run the executable

in the unpacked directory or use program shortcuts from the installer,

if available. On Linux, make sure you have the SDL2 libraries installed

on your system (e.g., libsdl2-2.0-0 and libsdl2-ttf-2.0-0 on Ubuntu).

For Windows (XP no longer supported), the SDL2 and all other needed libraries

are included in the game's binary archive.



Max OS X binaries for the few most popular OS versions are accessible

from Homebrew via `brew install allureofthestars`,

which also takes care of all dependencies.



Screen and keyboard configuration

---------------------------------



The game UI can be configured via a config file.

The default config settings, the same that are built into the binary,

are on github at [GameDefinition/config.ui.default](https://github.com/AllureOfTheStars/Allure/blob/master/GameDefinition/config.ui.default).

When the game is run for the first time, or whenever the config file

is deleted, the file is written to the default user data location,

which is `~/.Allure/` on Linux,

`C:\Users\\AppData\Roaming\Allure\`

(or `C:\Documents And Settings\user\Application Data\Allure\`

or something else altogether) on Windows

and `Inspect/Application/Local Storage` under RMB menu

when run inside the Chrome browser.

If the user config file is outdated or corrupted, it's automatically

moved away together with old savefiles. At the next game start,

the new default config file appears at its place.



Screen fonts and, consequently, window size can be changed by editing

the config file in the user data folder. The default bitmap font

`16x16xw.bdf` used for the game map covers most national characters

in the Latin alphabet (e.g. to give custom names to player characters)

and results in a game window of exactly 720p HD dimensions. The `8x8xb.fnt`

bitmap font results in a tiny window and covers latin-1 characters only.

The config file parameter `allFontsScale` permits further window size

adjustments, automatically switching to the scalable version of the large

game map font (`16x16xw.woff`). Config file option `chosenFontset` governs

not only the main game map font, but also the shape of the rectangular fonts,

if any, in which longer texts are overlaid over the map.



For high resolution displays and/or if fullscreen mode is requested

in the configuration file, `allFontsScale` needs to be set.

E.g., scale 3 works for 4K displays. Otherwise, the letters may be

too small or, in fullscreen or on retina displays in OS X,

the screen may be automatically scaled as a whole, not each letter

separately, softening letter edges of the square fonts that should

rather be pixel-perfect and crisp.



If you don't have a numeric keypad, you can use the left-hand movement

key setup (axwdqezc) or Vi editor keys (aka roguelike keys) or mouse.

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 the Control key instead. The game is fully playable with mouse only,

as well as with keyboard only, but the most efficient combination

may be mouse for menus, go-to, inspecting the map, aiming at distant

positions and keyboard for everything else.



If you run the ANSI terminal frontend (`--frontendANSI` on commandline),

then numeric keypad (especially keypad `*`, `/` and `5`) may not work

correctly, depending on the terminal emulator you use. Toggling

the Num Lock key may help or make issues worse. As a work around

these issues, numbers are used for movement in the ANSI frontend,

which sadly prevents the number keys from selecting heroes.

The commands that require pressing Control and Shift together won't work

either, but fortunately they are not crucial to gameplay.



Some effort went into making the ANSI frontend usable with screen readers,

but without feedback it's hard to say how accessible that setup is.

This doesn't work on Windows, due to extra code that would be required.

As a side effect of screen reader support, there is no aiming line

nor path in ANSI frontend and some of map position highlighting

is performed using the terminal cursor. Screen readers may also work

better with animations turned off, using `--noAnim` or the corresponding

config file or main game menu options.



Compiling native binary from source

-----------------------------------



To compile with the standard frontend based on SDL2, 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 ghcjs[15] compiler and optionally the Google Closure

Compiler[16].



The latest official version of the game can be downloaded,

compiled for SDL2 and installed automatically using the 'cabal' tool,

which may already be a part of your OS distribution, but if it's too old

(version 3.4 or later is required) you can download the whole current

compilation suite as described at https://www.haskell.org/downloads/.

You can get and run the Allure of the Stars package from Hackage[3] as follows



    cabal update

    cabal install Allure

    ~/.cabal/bin/Allure



For a newer, unofficial version, clone the game source from github[5],

clone a matching LambdaHack library snapshot into ../LambdaHack and run



    cabal run --project-file=cabal.project.LH.dir



Alternatively, if you'd like to develop in this codebase,

the following speeds up the turn-around a lot



    cp cabal.project.local.development cabal.project.local



and then you can compile (and recompile) with



    cabal build



and run the game with



    make play



The SDL2 frontend binary also contains the ANSI terminal frontend

(`--frontendANSI` on commandline) intended for screen readers

and a simplified black and white line terminal frontend (`--frontendTeletype`)

suitable for teletype terminals or a keyboard and a printer (but it's going

to use a lot of paper, unless you disable animations with `--noAnim`).

The teletype frontend is used in CI and for some tests and benchmarks defined

in Makefile. The terminal frontends leave you on your own regarding font

choice and color setup and you won't have the colorful squares outlining

special positions that exist in the SDL2 frontend, but only crude

cursor highlights. The terminal frontends should run on Windows,

but Windows disables console for GUI applications, so they don't.



Testing and debugging

---------------------



Integration tests can be run and displayed with



    cabal test --test-show-details=direct



The [Makefile](https://github.com/AllureOfTheStars/Allure/blob/master/Makefile)

contains many sample automated play test commands.

Numerous tests that use the screensaver game modes (AI vs. AI)

and the teletype frontend are gathered in `make test-locally`.

Some of these are run by CI  on each push to github.

Test commands with prefix `frontend` start AI vs. AI games with

the standard SDL2 frontend to view them on.



Run `Allure --help` to see a brief description of all debug options.

Of these, the `--sniff` option is very useful (though verbose

and initially cryptic), for displaying the traffic between clients

and the server. Some options in the config file may prove useful

for debugging too, though they mostly overlap with commandline options

(and will be totally merged at some point).
