Since Flash Player 9, we’ve been able to use the BitmapData.draw() method in order to capture visual data from a display object. The major limitation of using this method, is that it will render the visual at the stage quality with which the swf has been embedded/compiled. One trick to get around this is to […]

In the past, if we wanted to copy some data from a camera object to a bitmap, we would need to draw the data from the display object using flash.display.BitmapData.draw() and then manipulate it in some way. This is problematic at times… if there is no way of knowing whether we have valid bitmap data

In the past, we’ve been able to attach a local camera to Video display objects within Flash Player with relative ease. The flash.media.Video object, of course, is part of the traditional display list and is not accelerated by the system GPU whatsoever. Using the newer flash.media.StageVideo object, we can implement a GPU-accelerated video display beneath

With Flash Player 11.3 and above, the ability to listen for a frame label event is now included in the runtimes. For example; if you have a MovieClip symbol with a certain set of animation within it, and you have a number of frame labels defined upon the symbol’s timeline… you can now listen for

With Flash Player 11.3 and above, the ability to detect a mouse release outside of embedded Flash content makes a triumphant return! Missing in ActionScript 3.0 from Flash Player 9 onward, crafty developers have come up with some strange hacks to compensate for the missing event – but with the modern Flash Player runtime such

We’re looking all the way back to Flash Player 10.2 for a peek at native mouse cursor support! This feature allows us to use bitmap based mouse cursors that run at the OS level rather than inside the display list in Flash Player. Huge performance gains!

For most of my “AS3 Quickie” series, I’ve focused on Flash Player 11.2-11.4, but really have plans to cover all sorts of interesting bits in the recent runtimes – even some additions with Flash Player 10. For those who would like a comprehensive guide to everything new in Flash Player 11 and AIR 3, O’Reilly

Another great feature in Flash Player 11.2 is the combination of the mouseLock boolean in flash.display.Stage along with the ability to read movementX and movementY from MouseEvent.MOUSE_MOVE. When used within Flash Player, we must be in fullscreen for mouse lock to be enabled and the relative mouse coordinates made available. The primary focus of this

One of the great new features introduced with Flash Player 11.2 is the ability to detect when the runtime throttles, pauses, or resumes normal activity through the flash.events.ThrottleEvent class. This is useful for saving state, or pulling back our activity when a throttle is detected. What does the throttle actually do? Well, if you have

One of the great new features introduced with Flash Player 11.2 is the ability to intercept the right-click from a user’s mouse. A simple MouseEvent listener can be added to the Stage or any object which extends flash.display.InteractiveObject. Not only does this have the effect of completely removing the right-click menu from Flash content, but
