Use Math.atan2. So handy but forgetable. var targetAngle:Number = Math.atan2(mouseY - this.y, mouseX - this.x); var angle:Number = targetAngle * (180/Math.PI) - this.rotation = angle;

If you've set 'cancelable' to true in your event dispatch call, you can call e.stopPropagation(); To stop the event in its bubbling track at the first listener. Good if you've got a CLOSE event for example, and want the first parent who can handle closing things to close it rather than higher great-grandaddy clips.

Just a wee code snippet in case I need it again one day. Adding stylesheet functionality I'd usually use external CSS for from within the actionscript. Pretty easy: static private function setStyleSheet():void { styleSheet = new StyleSheet(); // create object for each style //links var a:Object = { color: "#FF0000" } styleSheet.setStyle("a", a); var hover:Object...

Basic printing in AS3: var my_pj:PrintJob = new PrintJob(); if (my_pj.start()) { try { my_pj.addPage([params]); } catch(e:Error) { // handle error } my_pj.send(); } Where you replace [params] with the Sprite you want to print. If you want to print the provided clip to the print page width, you can resize it to the right... Continue Reading →

SharedObjects are awesome, store variables locally on the users machine if you're unable to use a database etc. to store it. Here's some code from something using it to increase / store a viewCount variable. public function createSo():void { //create the local Shared Object try { cookie = SharedObject.getLocal(String(moduleID)); // direct reference to the moduleID's...

Some useful snippets of code for dealing with the date function in Flash. Needed this stuff when using a database provided start date for a user using an application, so as to know how many days had elapsed since they'd 'started' so had access to new stuff. var then:Number = Date.parse("Oct 25 2010"); var now:Number...

To stop Flash caching every URLRequested file you pull in, you need to trick flash into thinking the file is different. You can do this by changing the URL with a date/time reference, so the URL is different every time. Try sticking the below on the end of the url to load: "&nocache=" + new... Continue Reading →

Just a silly wee snippet - often one might forget the -.5! var randomIndex:Number = Math.round(Math.random() * myArray.length-.5);

function topicNavHandler(event:MouseEvent):void { switch(event.type) { case MouseEvent.ROLL_OVER: trace("rollover!"); break; case MouseEvent.ROLL_OUT: trace("ROLLOUT!"); break; }
