Get the full engine here. Be careful examples are update with the last code version on the Citrus Engine's GitHub. It may have differences with the SWCs build.

The Citrus Engine is a professional-grade, scalable Flash game engine built for industry-quality games. It is built upon modern Flash programming practices, allowing you to focus on making your game awesome! It comes built-in with a "platformer" starter-kit, which you can use to easily make awesome 2D or 3D sidescrolling games.

The Citrus Engine is not only made for platformer games, but for all type of games. It offers a nice way to separate logic/physics from art.

It offers many options, you may use :

  • select between : the classic flash display list, blitting, Starling (including Feathers) and Away3D.
  • select between : Box2D, Nape, AwayPhysics and a Simple math based collision detection.
  • a simple way to manage object creation, and for advanced developers : an entity/component system and object pooling.
  • a LevelManager and a LoadManager which may use Flash Pro as a level editor.
  • a Console, Sound management class, Keyboard and input handler...

  • lib : the different swcs used by some demo.
  • src : different demos ready to use! You just need to copy & paste the Main from the package you want into the src/Main.as and the demo will run. Be careful with package & import.
