= Operation Lambda README (Version 1.0 alpha 3) 2009-06-21 == What is Operation Lambda? Operation Lambda is a remake of the original Operation Lambda, a fantastic action/puzzle game for the Apple IIgs by Bret Victor. To quote the author, "My biggest IIgs production. A logic/action game, where you work your way through a space station under distress, deflecting laser beams and saving hostages. 100 levels of fun and excitement." The original Operation Lambda, released in 1996, was written entirely in 65816 assembly and never available for anything other than the IIgs. This version is a remake written entirely in Ruby, and should run on more or less any modern computer (though not, alas, on a IIgs). === Relevant Links 1.

SDL: http://libsdl.org/ == Requirements If you are using a pre-packaged copy of Operation Lambda for Windows or OS X, you should not need any extra software. You can skip to the next section. If you have downloaded the Operation Lambda source, you will need to have these programs to be able to play the game: * ruby >= 1.8.6, including 1.9.x * gosu >= 0.7.11* * texplay >= 0.1.0 Older versions might work, but they have not been tested. Please note, on Windows and Linux there seem to be problems using TexPlay with versions of Gosu newer than 0.7.11. This is expected to be fixed soon. On OS X, versions up to and including 0.7.13.3, work fine. This should be fixed in Gosu 0.7.13.4. If you have Mac OS X or Linux, you probably already have ruby installed. Windows users can get it from http://www.ruby-lang.org/ . The simplest way to install Gosu is with RubyGems, with which you would just run `gem install gosu`. Alternatively, download it at http://www.lib-gosu.org == Install If you have a pre-packed copy of Operation Lambda, just double-click the included Operation Lambda.app (if on OS X) or Operation Lambda.exe (if on Windows.) If you are running the game from source, just run 'ruby OperationLambda.rb` in the directory containing the source. If you installed Gosu via RubyGems, and you have a ruby version earlier than 1.9, you'll likely need to run `ruby -rubygems OperationLambda.rb` instead. == How to Play === Menu Controls Navigation: Arrow keys or Tab and Shift-Tab Selection: Space-bar/Enter/Return Back/Quit: Escape === Gameplay Controls Gameplay controls can be configured in the 'Settings' menu. The default controls are: Move player: Arrow keys Fire pistol: Z Turn mirror: X Pause menu : Escape === Objective Travel through each level, rescue the hostages, and get to the exist without being shot or blown up. Don't let the hostages get killed either! Details on what objects do what (with pictures) are available through the in- game help, accessed from the 'Info' menu. === Time and Score There is a timer in Operation Lambda; the amount of time available to you varies between levels; you also have less time available in harder difficulty levels. The more time you have left when you finish the level, the greater the bonus added to you score. In Relaxed mode, that is all that the timer does. In Easy mode and higher, if you run out of time, you lose a life. Higher difficulty levels give you a score multiplier compared to lower difficulty levels. == The Level Builder The Level Builder is fully functional, but not particularly polished at this time. If you want to tinker with it, though, feel free. Note that among other problems, you cannot set the keys used for previous/next 'tool'. They are hard-coded to '[' and ']', respectively. All other keys can be changed from the Settings menu. Note that you cannot edit the built-in levelset. You can, however, create a copy of it using the 'Clone Levelset' item in the Level Builder menu, then edit the copy. == History 1.0 alpha 3 - 2009-06-21 * Fixed laser-overlap-in-switch bug.
