Jam game made in 72 hours, made with LibGDX and Artemis-ODB. Tested for desktop and html5 via gwt.
This particular game uses odb 2.1 fluid entities!
Didn't get the web version done before submission hour so had to rig a few things at the last moment, specifically how the shader operates is a bit rushed.
Artemis Entity System takes a way a lot of the lifecycle management, and composition is a natural match for a time constrained Jam. While made in a rush, I hope this code gives you an idea or two how to benefit from using an entity system in your project.
While the meat is with peeking at the systems and components, you might like to compile the game!
The project was created on top of libgdx-artemis-quickstart, which uses gradle for build automation, and snapshot versions of artemis and libgdx. gradlew desktop:run should run the game. See the libgdx wiki for how to use gradle with your ide.
