Simplify your Box2D projects with QuickBox2D

In this quick example I am going to add a sphere to the stage and make it draggable.

Before looking at this script, take a look at Dragging objects with Box2D Flash to see how many lines of code I needed to make those crates draggable.

This is what you need with QuickBox2D:

package　{
　import　flash.display.MovieClip;
　//　importing　required　library
　import　com.actionsnippet.qbox.*;
　//　it　must　be　a　MovieClip!!　With　a　Sprite　it　won't　work!
　public　class　quickbox　extends　MovieClip　{
　　public　function　quickbox()　{
　　　//　setting　up　the　QuickBox2D　world
　　　var　qb:QuickBox2D=new　QuickBox2D(this);
　　　//　default　fill　color
　　　qb.setDefault({lineAlpha:0,　fillColor:0xff0000});
　　　//　automatic　stage　walls　creation!!!!!!!
　　　qb.createStageWalls();
　　　//　adding　a　ball...　that　easy...
　　　var　ball:QuickObject=qb.addCircle({x:3,y:3,restitution:0.9,lineAlpha:1,fillColor:0x00ff00,allowSleep:false,fixedRotation:true});
　　　//　automatic　mouse　dragging!!!
　　　qb.mouseDrag();
　　　//　starting　the　simulation
　　　qb.start();
　　}
　}
}

and this is what you get…
