forEach is a nice wee function to speed some bizzo up on particular arrays. myArray.forEach(myFunction); // for each item in this array, runs myFunction function. } public function myFunction(element:*, index:int, arr:Array):void { // element returns the current item (ie. myArray[0] etc. and the rest is clear) }

This'll reset the matrix to it's default and in so doing will clear any 3d rotation fuzziness that may have been generated if you use rotationX or rotationY or anything. myDisplayObject.transform.matrix = new Matrix(1, 0, 0, 1, myDisplayObject.x, myDisplayObject.y);

// flip vertical scaleY *= -1; // flip horizontal scaleX *= -1;

Pretty standard here. Say you've a class which you wish to extend a parent class - but you want that parent class to be able to access all the display objects within the child class. You might get a 1152 error - naming conflict between the two. A way around this is to make that... Continue Reading →

AS3 You can do it with a link event: html text would be: <a href='event:moveUp'>UP</a> listener on the field: myHTML.addEventListener(TextEvent.LINK, linkHandler); function linkHandler(event:TextEvent):void { trace(event.text); // traces 'moveUp' } See this page if that's not enough: http://blog.circlecube.com/2008/12/portfolio/asfunction-texteventlink-tutorial-for-as3-flash-html-link-to-call-actionscript-function-tutorial/ In as2 it was a bit different, see below: AS2: You can use htmlText to call AS functions....

Pretty basic stuff here, but for each is quite handy for looping through an array that may hold more than one type of content for each (var o:Object in gridArray) { // do something } That'll pull out each object in gridArray for you to manipulate as o.

There is no onReleaseOutside call in AS3. So, to get that, the best way is to, when your MOUSE_DOWN event function is called, to add a MOUSE_UP event listener to the stage. Then remove that listener when the event is triggered. eg. myBtn.addEventListener(MouseEvent.MOUSE_DOWN, downHandler): function downHandler(event:MouseEvent):void { stage.addEventListener(MouseEvent.MOUSE_UP, upHandler); // do whatever on mouseDown eg....

If you trace a colour you've input as 0xFFFFFF, it'll trace back as some big number (no time to do exmaple properly). If you need to say, then reuse this color number and put it back in to htmltext formatting for colour (which deals in hex) - you can use toString(16) to convert it back... Continue Reading →

fieldColor.substring(2, fieldColor.length); That'll strip the first two items from fieldColor (ie. return the rest, minus the first 2 characters)

See this thread: http://stackoverflow.com/questions/792451/want-to-send-parameters-with-custom-dispatch-event Incase they remove it, public class YourEvent extends Event { public static const SOMETHING_HAPPENED: String = "somethingHappend"; public var data: Object; public function YourEvent(type:String, date: Object, bubbles:Boolean=false, cancelable:Boolean=false) { data = this.data; super(type, bubbles, cancelable); } override public function clone():Event { return new YourEvent (type, data, bubbles, cancelable); } }
