Hermes is an experimental game engine leveraging Java's object-oriented systems and the simplicity of Processing to provide an architecture for rapid sketching and prototyping of games and simulations.
Hermes.zip contains a completely built version of the library with examples and documentation. To install, drag the unzipped folder into the 'libraries' folder in your Processing sketchbook.
A beta release of Hermes supporting Processing 3 is available here, but please check the release page for caveats.
See the Tutorial for an introduction to making games with Hermes. See the javadocs for full code and API documentation.
The full source code of the library is in the hermes/ folder; unit tests are in hermesTest/. The library itself is in the package hermes, and testing code is in hermesTest. In the pre-built download, source is included in the src/ folder. See the wiki for details on building the library from source.
Hermes is available under the MIT license. See 'LICENSE' for full details.
