Plugins

You can easily create plugins for the game by putting a new folder into plugins/ with the name of your plugin and then compiling your code into a shared library placed inside this folder named ".so" (-shared -fpic). You might want to include the game.h file from plugins/game/game.h. Have a look into it to see available API. See the existing plugins for examples.

Dependencies

If you want to make a plugin that needs to use ABI from another plugin (including the game itself), make sure to depend on that plugin. To add dependencies to a plugin, create a file named dependencies.txt in the plugin folder. Put the names of all plugins your plugin depends on into that file. You can use spaces or newlines as seperators.

Makefile inclusion

All Makefiles that are placed in plugin directories are included by the main Makefile, so you might want to include a makefile in your plugin. The plugins target simply depends on ${PLUGINS}, so just add things to this in your plugin Makefile to add them to the plugins target (usually your plugin.so)
