Eiffel Game 2

A Game library for ISE Eiffel.

This is a library for game development using the Eiffel Language. The library is compatible with the IDE EiffelStudio 16.05 and newer from ISE.

The library is compatible with Linux, macOS & Windows. It should also work with any other operating system (FreeBSD, Android, IOS, etc.), but it is not officially supported.

The Audio and Audio_Sound_File sub-libraries are under the LGPL license. Every other sub-libraries are under the zlib license. Every examples are under the GPL license.

The project uses those libraries: SDL2, SDL2_image, SDL2_gfx, SDL2_ttf, OpenAL, Libsndfile, libmpg123, GLEW.

Installation on Linux (Ubuntu)

  • I assume that you already have a functional EiffelStudio on your system. If not, install it.
  • If you obtained the library sources by cloning the git repository, fetch submodules (run git submodule init and git submodule update in the library folder)
  • Rename the library folder (containing this README.md) to game2.
  • Add the game2 folder library in the contrib/library folder of EiffelStudio. This folder is usually under /usr/lib/EiffelStudio_XX.XX or /usr/local/Eiffel_XX.XX.
  • Install the C libraries SDL2, SDL2_image, SDL2_gfx, SDL2_ttf, OpenAL, libsndfile, libmpg123, OpenGL, GLU, libepoxy along with their development toolkits and dependencies:
sudo apt-get install libsdl2-dev libsdl2-gfx-dev libsdl2-image-dev libsdl2-ttf-dev libopenal-dev libsndfile1-dev libmpg123-dev libepoxy-dev libgl1-mesa-dev libglu1-mesa-dev libglew-dev libavcodec-dev libavformat-dev libavutil-dev libswresample-dev libswscale-dev
  • Execute the compile_c_library.sh script (from the game2 directory).
  • Create a project and add the sub-libraries you need (.ecf files) in the project. (You can use the EIFFEL_LIBRARY environment variable to add those libraries. For example: $EIFFEL_LIBRARY/contrib/library/game2/game_core/game_core.ecf)

Note: If you have a dependency error while running the apt-get command like libsdl2-dev depending of libgles2-mesa-dev, install the latest and try this:

sudo apt-get install libgles2-mesa-dev
sudo apt-get install libsdl2-dev libsdl2-gfx-dev libsdl2-image-dev libsdl2-ttf-dev libopenal-dev libsndfile1-dev libmpg123-dev libepoxy-dev libgl1-mesa-dev libglu1-mesa-dev libglew-dev libavcodec-dev libavformat-dev libavutil-dev libswresample-dev libswscale-dev

Installation on Windows

  • Note: For an easy installation, see: https://github.com/tioui/Eiffel_Game2/tree/windows_build.
  • You must have a working EiffelStudio. If you don't have it already, install it.
  • Rename the library folder (containing this README.md) to game2.
  • Add the game2 library folder in the contrib/library folder of EiffelStudio. This folder is usually under C:\Program Files\Eiffel Software\.
  • Install the C library dependencies. To get them, download the files at https://github.com/tioui/Eiffel_Game2/raw/windows_build/C_libraries.zip. After extracting them, you should have a C_lib_win directory. Put the C_lib_win directory in the root directory of the Eiffel_Game2 repository.
  • Using the "EiffelStudio command prompt" (within your Start menu), execute the compile_c_library.bat script in the game2 directory.
  • Create a project and add the libraries you need (.ecf files) in the project. (You can use the EIFFEL_LIBRARY environment variable to add those libraries. For example: $EIFFEL_LIBRARY/contrib/library/game2/game_core/game_core.ecf)
  • Put all .dll files within C_lib_win\DLLXX\ in the new project directory or in C:\Windows\System32\.
