Ashley javadocs and wiki

Ashley, your favourite entity framework now has online javadocs and a wiki.


The javadocs correspond to the latest repository snapshot. Our Jenkins instance grabs the code, runs the tests, builds the jars and publishes the javadocs to the badlogic.com server. Kudos to Mario for the setup.

I just started putting stuff into the wiki yesterday so it’s pretty empty as of now. Expect more content soon!

Super Jumper Ashley remake


Ashley Super Jumper has been my weekend project. It is nothing more than a clone of the Libgdx demo game. The catch is that it goes for an entity system approach rather than the classic inheritance model. Naturally, it uses Ashley.

The point was to have a reference project folks could check out in order to understand how entity systems in general and Ashley in particular work.

Maybe one day, I’ll post a proper article explaining the design behind the entity systems at play in Super Jumper. I guess that could be useful.

Libgdx setup tool now supports Ashley

gdx-setup ashley

Last night I added Ashley support to the official Libgdx setup tool. Creating Libgdx projects that use Ashley entity framework is now even easier. Simply make sure you tick the Ashley checkbox before generating your project.

By the way, if you already have a a project, adding the extra dependency is also trivial.

  • Core project: com.badlogicgames.ashley:ashley:1.0.1
  • Android project: com.badlogicgames.ashley:ashley:1.0.1
  • GWT project: com.badlogicgames.ashley:ashley:1.0.1:sources

Remember that using Ashley in non Libgdx projects is also perfectly fine.

Ashley entity framework

Loads of stuff in the pipeline lately: new job, finishing my book and some Ashley development. What? You don’t know what Ashley is? Here is a brief, straight from GitHub.

A tiny entity framework written in Java. It’s inspired by frameworks like Ash (hence the name) and Artemis. Ashley tries to be a high-performance entity framework without the use of black-magic and thus making the API easy and transparent to use.

Long story short: Ashley is awesome.

Stefan Batchmann started the project on February 2013. Since he is rather busy making actual games, he asked me to look after the project and I gladly accepted.

Entity systems are really cool and can help you write cleaner game code, avoiding the classic inheritance hierarchy hell. This article does a pretty good job at explaining the benefits of entity systems.

It’s funny how strongly opinionated developers seem to feel towards entity systems. Some love them, some hate them. Have a read, experiment with Ashley and decide for yourself.

The readme will help to you get started. Please, do not hesitate to open an issue if you find any problems. If you send a pull request, you will have our unconditional love.

Expect more Ashley related articles soon!

Libgdx Cross-platform Development Cookbook announced

libgdx cross platform development cookbook

Almost a year ago, I started working on a Libgdx recipe book with Alberto Cejas, an old University mate. Now, Packt Publishing, have announced the project on their website, Libgdx Cross-platform Development Cookbook.

You can even pre-order a printed copy or the e-book version (DRM free).

Exciting times!

The book offers step-by-step guides on how to master Libgdx subsystems to build 2D games that run almost everywhere: Windows, GNU/Linux, Mac, Android, iOS and browsers. It only requires basic knowledge of games development and comes with a ton of sample code to help readers understand each topic.

I will post more information soon!
