openage

openage: a volunteer project to create a free engine clone of the Genie Engine used by Age of Empires, Age of Empires II (HD) and Star Wars: Galactic Battlegrounds, comparable to projects like OpenMW, OpenRA, OpenTTD and OpenRCT2. At the moment we focus our efforts on the integration of Age of Empires II, while being primarily aimed at POSIX platforms such as GNU/Linux.

openage uses the original game assets (such as sounds and graphics), but (for obvious reasons) doesn't ship them. To play, you require an original AoE II : TC installation or AoE II: HD (installation via Wine or Steam-Linux).

The foundation of openage:

Technology Component
C++17 Engine core
Python3 Scripting, media conversion, in-game console, code generation
Qt5 Graphical user interface
Cython Glue code
CMake Build system
OpenGL3.3 Rendering, shaders
SDL2 Cross-platform Audio/Input/Window handling
Opus Audio codec
nyan Content Configuration and Modding
Humans Mixing together all of the above

Our goals include:

  • Fully authentic look and feel
    • This can only be approximated, since the behaviour of the original game is mostly undocumented, and guessing/experimenting can only get you this close
    • We will not implement useless artificial limitations (max 30 selectable units...)
  • Multiplayer (obviously)
  • Matchmaking and ranking with a haskell masterserver
  • Optionally, improvements over the original game
  • AI scripting in Python, you can use machine learning
  • Re-creating free game assets
  • An easily-moddable content format: nyan yet another notation
  • An integrated Python console and API, comparable to blender
  • Awesome infrastructure such as our own Kevin CI service

But beware, for sanity reasons:

  • No network compatibility with the original game. You really wanna have the same problems again?
  • No binary compatibility with the original game. A one-way script to convert maps/savegames/missions to openage is planned though.

Current State of the Project

Dependencies, Building and Running

  • How do I get this to run on my box?

  • I compiled everything. Now how do I run it?

    • Execute ./run.
    • The convert script will transform original assets into openage formats, which are a lot saner and more moddable.
    • Use your brain and react to the things you'll see.
  • Waaaaaah! It

    • segfaults
    • prints error messages I don't want to read
    • ate my dog

All of those are features, not bugs.

To turn them off, use ./run --dont-segfault --no-errors --dont-eat-dog.

If this still does not help, try our troubleshooting guide, the contact section or the bug tracker.

Development Process

What does openage development look like in practice?

Can I help?

All documentation is also in this repo:

  • Code documentation is embedded in the sources for Doxygen (see doc readme).
  • Have a look at the doc directory. This folder tends to outdate when code changes.

macOS Version

Running openage on macOS worked in the past, and might or might not work right now.

Setting up continuous integration for this platform has some complications. Running a hackintosh VM seems to be not so legal, while buying dedicated hardware for it seems to be not so cheap. If you know of a legal and cost-free way of doing so or want to sponsor a semi-recent Mac Mini, please open a ticket in our issue tracker. Until then, PRs untested on macOS will make their way into the master branch and occasional breakage will occur.

Windows Version

The Windows port of openage is under development.

Setting up continuous integration for this platform has problems similar to the OSX version. If you know of a legal and cost-free way of acquiring and running a Windows VM, please open a ticket in our issue tracker. Until then, PRs untested on Windows will make their way into the master branch and occasional breakage will occur.

Contributing

  • Being typical computer science students, we hate people.
  • Please don't contact us.
  • Nobody likes Age of Empires anyway.
  • None of you is interested in making openage more awesome anyway.
  • We don't want a community.
  • Don't even think about trying to help.

Guidelines:

  • No bug reports or feature requests, the game is perfect as is.
  • Don't try to fix any bugs, see above.
  • Don't implement any features, your code is crap.
  • Don't even think about sending a pull request.
  • Please ignore the easy tasks that could just be done.
  • Absolutely never ever participate in this boring community.
  • Don't note the irony, you idiot.

To prevent accidental violation of one of those guidelines, you should never

cheers, happy hecking.
