The following table describes the differences between ActionScript 2.0 and 3.0.

	ActionScript 2.0	ActionScript 3.0	Comments
	Compiler directives
	#endinitclip	Removed
	#include	Removed	See the include statement for similar functionality.
	#initclip	Removed
	Constants
	false	false	The value false, rather than undefined, is the default value of a Boolean object.
	NaN	NaN	The value NaN, rather than undefined, is the default value of a Number object.
	newline	Removed	Use the escape sequence composed of the backslash character followed by the character 'n' ("\n").
	null	null	The value null, rather than undefined, is the default value of the Object and String classes.
	undefined	undefined	The value undefined can be assigned only to untyped variables; it is not the default value of any typed object.
	Global functions
	asfunction	flash.events.TextEvent	Replaced by the new event handling model. You now get the same functionality by using the syntax: Event: instead of asfunction:. When a user clicks the link, Flash Player dispatches a TextEvent object of type TextEvent.LINK, which your code can listen for with the addEventListener() method. Any text that you decide to include is stored in the event object's text property.

	_soundbuftime	flash.media.SoundMixer.bufferTime	Replaced by the bufferTime property of the SoundMixer class.
	this	this	Instance methods are bound to the instance that implemented the method; therefore, the this reference inside the body of an instance method always refers to the instance that implemented the method.
	Accessibility class	flash.accessibility.Accessibility
	isActive() Method	flash.accessibility.Accessibility.active	Changed from function to accessor property, name changed from isActive to active.
	updateProperties() Method	flash.accessibility.Accessibility.updateProperties()
	arguments class	arguments	The caller property has been removed.
	caller Property	arguments.callee	Removed. You can achieve the same functionality by passing arguments.callee from the caller function as an argument to the callee function. See the Examples section of arguments.callee for an example.
	Array class
	CASEINSENSITIVE Constant	Array.CASEINSENSITIVE	Data type changed to uint.
	DESCENDING Constant	Array.DESCENDING	Data type changed to uint.
	length Property	Array.length	Data type changed to uint.
	NUMERIC Constant	Array.NUMERIC	Data type changed to uint.
	RETURNINDEXEDARRAY Constant	Array.RETURNINDEXEDARRAY	Data type changed to uint.

	AsBroadcaster class	flash.events.EventDispatcher
	_listeners Property[read-only]	flash.events.EventDispatcher.willTrigger()	Not a direct equivalent. The willTrigger() method tells you whether any listeners are registered, but not how many.
	addListener() Method	flash.events.EventDispatcher.addEventListener()	Not a direct equivalent, because the ActionScript 3.0 event model lets you add event listeners to any object in the event flow, not just to the broadcasting object.
	broadcastMessage() Method	flash.events.EventDispatcher.dispatchEvent()	Not a direct equivalent, because the ActionScript 3.0 event model works differently. The dispatchEvent() method dispatches an event object into the event flow, while the broadcastMessage() method sends messages directly to each registered listener object.
	initialize() Method	Removed	There is no direct equivalent in ActionScript 3.0, but similar functionality is achieved by subclassing EventDispatcher. For example, the DisplayObject class extends EventDispatcher, so all instances of the DisplayObject and DisplayObject subclasses are capable of sending and receiving event objects.
	removeListener() Method	flash.events.EventDispatcher.removeEventListener()	Not a direct equivalent, because the ActionScript 3.0 event model lets you add event listeners to and remove them from any object in the event flow, not just the broadcasting object.
	BitmapData class	flash.display.BitmapData	ActionScript 3.0 uses the BitmapDataChannel class as an enumeration of constants that indicate which channel to use.

	rectangle Property[read-only]	flash.display.BitmapData.rect	Property was renamed for consistency with other members of the API.
	width Property[read-only]	flash.display.BitmapData.width	Data type changed from Number to int.
	copyChannel() Method	flash.display.BitmapData.copyChannel()	The srcChannel and destChannel parameters are now uint data types.
	draw() Method	flash.display.BitmapData.draw()	The source parameter is now IBitmapDrawable; DisplayObject and BitmapData both implement the IBitmapDrawable interface, so you can pass either a DisplayObject or a BitmapData object to the source parameter.
	fillRect() Method	flash.display.BitmapData.fillRect()	The color parameter is now a uint value.
	floodFill() Method	flash.display.BitmapData.floodFill()	Now accepts int values for x and y and a uint value for color.
	getColorBoundsRect() Method	flash.display.BitmapData.getColorBoundsRect()	Now accepts uint values for the mask and color parameters.

	pixelDissolve() Method	flash.display.BitmapData.pixelDissolve()	Now accepts an int value for the randomSeed and numPixels parameters and a uint value for thefillColor parameter. (The numPixels parameter was named numberOfPixels in ActionScript 2.0.)
	scroll() Method	flash.display.BitmapData.scroll()	Now accepts int values for the x and y parameters.
	setPixel() Method	flash.display.BitmapData.setPixel()	Now accepts int values for x and y and a uint value for color.
	setPixel32() Method	flash.display.BitmapData.setPixel32()	Now accepts int values for x and y and a uint value for color.
	threshold() Method	flash.display.BitmapData.threshold()	Now accepts uint values for the threshold, color, and mask parameters, and returns a uint value.

	_ymouse Property[read-only]	flash.display.DisplayObject.mouseY
	_yscale Property	flash.display.DisplayObject.scaleY
	getDepth() Method	flash.display.DisplayObjectContainer.getChildIndex()	ActionScript 3.0 provides direct access to the display list so depth is handled differently.
	onDragOut() EventHandler	flash.display.InteractiveObject dispatches event: mouseOut	Replaced in the new event model by a mouseOut event, after a call to InteractiveObject.setCapture().

Color values can be assigned directly by using ColorTransform class constructor or properties. ColorTransform objects can then be assigned to the colorTransform property of a Transform object, which in turn can be assigned to the transform property of a DisplayObject instance.
	Color Constructor	flash.geom.ColorTransform.ColorTransform()	Removed. You can specify color values by using the ColorTransform() constructor.
