Working With Large Arrays in Action Script

17 ביולי 2010

While working on partly connected system using flex technology I figured out quick enough that working with large data sets (thousands of records) is not applicable. Especially because i held a number of those sets which I needed to  cross reference in number of occasions. My solution was to create an indexed collection which i can benefit both worlds of Dictionary and ArrayCollection , with that in mind I designed and implemented the IndexedArrayCollection. The collection extends ArrayCollection and adds the capability of indexing a more

Box2D Flex Complex Shapes Mapping

13 ביולי 2010

One of the drawbacks in box2d is that it's not supporting concave polygon shapes . for that box2d flex employs several algorithms and converts a complex shape to a set of polygons (I took the idea from 3d modeling) at this point i would like to give credits to for he's shape outline algorithm for he's polygon2d both state that their algorithms are far from perfect but for a v0.2 it's a good start. in this case I'll start from the demo and more

Simple Box2D Flex Example

11 ביולי 2010

following my previous post announcing Box2D Flex framework i want to share some techniques via examples on how to use the library. First thing we create add a SkinableContentContainer to and drop some contorls inside it This, still, does not do anything fancy it just initializes box2d and registers & measures all controls inside our physics container. next step we add some bindable controls that will change our physics gravity and debug and the bindable properties to our physics container now we can play with the gravity sliders and more

Announcing Box2D Flex framework

Prefix In a previous post demonstrating box2d integration with flex I made a promise (mainly to myself) to share the demo code. When I started to review with sharing in mind it looked cumbersome and overly verbose. So I started cranking on it fixing and straightening the code & architecture and step by step I realized that I'm creating a small Integration layer rather then a POC. Announcing Box2DFlex Box2DFlex framework allows you easely integrate box2d into flex framework using mxml. The framewok helps easy integration with more

CSS Mask in HTML 5

8 ביולי 2010

< התוכן שמופיע כאן מועמד לסטנדרטיזציה ב html5  יתכן וחלק מהדברים לא יעבדו כרגע על כל דפדפן > בהמשך לפוסט הקודם על css ב html5 עשיתי עוד ניסוי קטן לגבי masks (אולי  מיסוכים?) . רציתי להחליף צבעים תכנותית לתמונה קיימת . כדי לעשות את זה ניגשתי למלאכה והתחלתי לנבור ברשת , די מהר מצאתי שגם לזה יש פתרון ב css3. מיקמתי שני div אחד מעל השני - בראשון תמונה של מכונית (המכונית חייבת להיות לבנה כדי שנוכל לצבוע אותה בקלות)
