BUILDING A SIMPLE GAME WITH FLASH PRO

BEGINNER’S TUTORIAL
You are going to learn Citrus Engine (http://citrusengine.com) basics. Citrus Engine
is lightweight GPU accelerated game engine for Flash and AIR and includes
platformer kit for side-­‐scroller platform games. It runs on top of Starling Framework
(2D) and Away3D framework (3D) and you can choose one of the physics engines
that are included as well – Box2D, NAPE, AwayPhysics. For our game we are going to
use Starling + Box2D combination.
Setup the most basic scene with Citrus Engine.
Start Flash Builder 4.7 and later we are going to use Flash Pro for level design and
animations , but project management and coding will be done in Flash Builder as it’s
more suitable for it. Design = Flash Pro, Programming = Flash Builder.
Create a new project in Flash Builder
File -­‐> New -­‐> ActionScript Project
(name the project MAXBeginner or similar)
Link Citrus library
Right click on the project -­‐> Properties -­‐> ActionScript Build Path -­‐> Add SWC
(locate CitrusEngine’s SWC file) -­‐> OK
In the main class add following code:
package
{
import citrus.core.starling.StarlingCitrusEngine;
}
[SWF(frameRate="60", width="1024", height="768")]
public class MAXBeginner extends StarlingCitrusEngine
{
public function MAXBeginner()
{
setUpStarling(true);
}
}
state = new GameState();
