If you want to get this done simply and quickly, you can use this rotateAroundCenter function:

 private function rotateAroundCenter (ob:*, angleDegrees:Number, ptRotationPoint:Point) {
      var m:Matrix=ob.transform.matrix;
      m.tx -= ptRotationPoint.x;
      m.ty -= ptRotationPoint.y;
      m.rotate (angleDegrees*(Math.PI/180));
      m.tx += ptRotationPoint.x;
      m.ty += ptRotationPoint.y;
      ob.transform.matrix=m;
 }

Here’s a screenshot:

Hey, I just did a quick experiment with bitmaps in AS3. Nothing fancy, I just loaded in an external JPEG, resized it into 3 different sizes and then drew them to stage. I’m sure someone can use this. For now, everything is hard-coded and the code is right in the .FLA. Maybe I’ll try and make a nice class out of this, although I’m sure there’s already one out there. Anyway, check out the code or download the FLA.

var mediaLoader:Loader = new Loader();
var bmFullsize:Bitmap;
var bmHalfsize:Bitmap;
var bmThumbsize:Bitmap;
 
mediaLoader.load(new URLRequest("ostrich.jpg"));
mediaLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, resizeImages);
 
function resizeImages(e:Event):void
{
	bmFullsize = new Bitmap(e.target.content.bitmapData.clone());
	bmHalfsize = new Bitmap(e.target.content.bitmapData.clone());
	bmThumbsize = new Bitmap(e.target.content.bitmapData.clone());
	bmFullsize.width = 300;
	bmFullsize.height = 300;
	bmFullsize.smoothing = true;
	bmHalfsize.width = 150;
	bmHalfsize.height = 150;
	bmHalfsize.x = bmFullsize.width;
	bmHalfsize.smoothing = true;
	bmThumbsize.width = 75;
	bmThumbsize.height = 75;
	bmThumbsize.x = (bmFullsize.width + bmHalfsize.width);
	bmThumbsize.smoothing = true;
	showImages();
}
 
function showImages():void
{
	addChild(bmFullsize);
	addChild(bmHalfsize);
	addChild(bmThumbsize);
}

Just now I ran into a problem when trying to use to VideoPlayer class for the first time.  Dang.

Click above for a giant layout of all the APE classes and the way they inherit each other. Definitely helpful.

If you have any interest in Flash + Math/Physics, I recommend you try out APE (the Actionscript Physics Engine) library by Alec Cove. It’s a set of AS3 classes that will easily let you create a world of particles that are affected by physics. If you’ve ever thought about making an action-type game, this might be the place for you to start.

Just today I stumbled upon some great examples by a guy named Andrew Garrahan that were posted to Google Group called APE General.

Follow this link to see the examples: APE Cornerstones: Basic Examples

(Thanks Andrew, these should really help me get started)

There’s also some other great examples in this group and I imagine it will grow as well. I hope this helps someone out there!

I had some trouble with the CS3 UIScrollbar properly latching onto a dynamic textbox earlier this week. I found a solution and I thought I’d share.

Any good animation changes camera angles from time to time. Unfortunately these is no easy way to do this in Flash… by itself.

However, a fellow named Sham Bhangal wrote a little application using actionscript that allows us to have a virtual camera that can be animated within scenes.

Whether you’re just starting out in Flash, or have been playing with it for some time, chances are you have run into problems with sound synchronization. If you’re new to Flash and have been experiencing problems in this area, chances are the solution is very simple as I will explain in a moment. However, if the following isn’t news to you and you’re still having problems, keep reading, the solution may follow.
