| Appendixes | Conventions | Frames
The following table describes the differences between ActionScript 2.0 and 3.0.
| ActionScript 2.0 | ActionScript 3.0 | Comments | |
|---|---|---|---|
| Compiler Directives | |||
| #endinitclip | Removed | The #endinitclip directive identifies the end of initialization code in ActionScript 2.0, but has no use in ActionScript 3.0. |
|
| #include | Removed | See the include statement for similar functionality. |
|
| #initclip | Removed | The #initclip directive identifies the beginning of initialization code in ActionScript 2.0, but has no use in ActionScript 3.0. |
|
| 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.text.TextField dispatches event: link | 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. |

|
| _parent | flash.display.DisplayObject.parent | Replaced by the parent property of the DisplayObject class. |
|
| _quality | flash.display.Stage.quality | Replaced by the quality property of the Stage class. |
|
| _root | flash.display.DisplayObject.stage | Removed. The closest equivalent is the Stage, which serves as the root of the ActionScript 3.0 display list. | |
| scroll | flash.text.TextField | Removed. Replaced by the scrollH and scrollV properties of the TextField class. |
|
| _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. |
|
| Operators | |||
| add (concatenation (strings)) | Removed | Use the concatenation (+) operator instead. | |
| eq (equality (strings)) | Removed | Use the equality (==) operator instead. | |
| gt (greater than (strings)) | Removed | Use the greater than (>) operator instead. |
|
| ge (greater than or equal to (strings)) | Removed | Use the greater than or equal to (>=) operator instead. |
|
| <> (inequality) | Removed | Use the inequality (!=) operator instead. |
|
| instanceof | is | Although the instanceof operator is available, it only checks the prototype chain, which is not the primary inheritance mechanism in ActionScript 3.0. Use the is operator to check whether an object is a member of a specific data type. |
|
| lt (less than (strings)) | Removed | Use the less than (<) operator instead. |
|
| le (less than or equal to (strings)) | Removed | Use the less than or equal to (<=) operator instead. |
|
| and (logical AND) | Removed | Use the logical AND (&&) operator instead. |
|
| not (logical NOT) | Removed | Use the logical NOT (!) operator instead. |
|
| or (logical OR) | Removed | Use the logical OR (||) operator instead. |
|
| ne (not equal (strings)) | Removed | Use the inequality (!=) operator instead. |
|
| Statements | |||
| delete | delete | The delete operator works only on properties of objects, but not on variables that hold references to objects. |
|
| import | import | The import statement is not optional. To use a class, you must import it, whether or not you use a fully qualified name. |
|
| intrinsic | Removed | ActionScript 3.0 has a similar, but not identical, keyword named native. The native keyword is similar to intrinsic in that it directs the compiler not to expect a function body, but is dissimilar in that native has no effect on compile-time type checking. |
|
| private | private | The ActionScript 3.0 private keyword specifies that an identifier is visible only within a class, and does not extend to subclasses. Moreover, in ActionScript 3.0 the private keyword is enforced at both compile time and run time. |
|
| set variable | Removed | Use the assignment (=) operator instead. |
|
| super | super | In ActionScript 3.0, the call to super() in a subclass constructor does not have to be the first statement in the constructor body. |
|
| 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 | ||
| caller Property | 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. | |
| UNIQUESORT Constant | Array.UNIQUESORT | Data type changed to uint. | |
| Array Constructor | Array.Array() | Parameter changed to use the ...(rest) parameter format. | |
| push() Method | Array.push() | Parameter changed to use the ...(rest) parameter format. | |
| sort() Method | Array.sort() | Data type of the options parameter changed to uint. |
|
| sortOn() Method | Array.sortOn() | Data type of the options parameter changed to uint. The ActionScript 3.0 version also has added functionality; you can now sort on more than one field name by passing an array of objects for the fieldName parameter, and each sort field can have its own matching options parameter if you also pass in a matching array of options flags for the options parameter. |
|
| splice() Method | Array.splice() | The parameters can have any data type, but the preferred data types are int and uint. The value parameter changed to the ...(rest) parameter format. |
|
| unshift() Method | Array.unshift() | The value parameter changed to the ...(rest) format. Data type of the return value 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 the EventDispatcher class. 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. | |
| height Property[read-only] | flash.display.BitmapData.height | Data type changed from Number to int. | |
| rectangle Property[read-only] | flash.display.BitmapData.rect | Property 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 sourceChannel 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 the x and y parameters and a uint value for color. |

|
| getPixel32() Method | flash.display.BitmapData.getPixel32() | Now accepts int parameter values and returns a uint value. |
|
| hitTest() Method | flash.display.BitmapData.hitTest() | Now accepts uint values for the firstAlphaThreshold and secondAlphaThreshold parameters. |
|
| loadBitmap() Method | Removed | This function is no longer needed because of the new bitmap support in ActionScript 3.0. | |
| merge() Method | flash.display.BitmapData.merge() | Now accepts uint values for the multiplier parameters. | |
| noise() Method | flash.display.BitmapData.noise() | Now accepts an int value for the randomSeed parameter and uint values for the low, high, and channelOptions parameters. |
|
| perlinNoise() Method | flash.display.BitmapData.perlinNoise() | Now accepts an int value for the randomSeed parameter and uint values for the numOctaves and channelOptions parameters. |
|
| pixelDissolve() Method | flash.display.BitmapData.pixelDissolve() | Now accepts an int value for the randomSeed and numPixels parameters and a uint value for the fillColor parameter. (The numPixels parameter is 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 the x and y parameters and a uint value for color. |
|
| setPixel32() Method | flash.display.BitmapData.setPixel32() | Now accepts int values for the x and y parameters 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. |

| tabEnabled Property | flash.display.InteractiveObject.tabEnabled | ||
| tabIndex Property | flash.display.InteractiveObject.tabIndex | ||
| _target Property[read-only] | Removed | ActionScript 3.0 identifies display objects directly; therefore, identifying a display object by its path is no longer necessary. | |
| trackAsMenu Property | flash.display.SimpleButton.trackAsMenu | ||
| _url Property[read-only] | Removed | See DisplayObject.loaderInfo.url. | |
| useHandCursor Property | flash.display.SimpleButton.useHandCursor | ||

| copy() Method | flash.ui.ContextMenu.clone() | ||
| hideBuiltInItems() Method | flash.ui.ContextMenu.hideBuiltInItems() | ||
| onSelect() EventHandler | flash.ui.ContextMenu dispatches event: menuSelect | Instead of invoking the onSelect() event handler, the ActionScript 3.0 class dispatches a menuSelect event. |
|
| ContextMenuItem class | flash.ui.ContextMenuItem | The ContextMenuItem class is now part of the flash.ui package. | |
| caption Property | flash.ui.ContextMenuItem.caption | ||

| clone() Method | flash.filters.DropShadowFilter.clone() | Now returns a BitmapFilter object instead of a DropShadowFilter object. | |
| Error class | Error | Added a new getStackTrace() method to assist in debugging. |
|
| ExternalInterface class | flash.external.ExternalInterface | Parameters changed for two methods in this class. | |
| addCallback() Method | flash.external.ExternalInterface.addCallback() | The ActionScript 3.0 version of this method does not accept the instance parameter. The method parameter is replaced by a closure parameter, which can take a reference to a function, a class method, or a method of a particular class instance. In addition, if the calling code cannot access the closure reference for security reasons, a SecurityError exception is thrown. |
|
| call() Method | flash.external.ExternalInterface.call() | If a problem occurs, the ActionScript 3.0 version of this method throws an Error or SecurityError exception, in addition to returning null. |
|
| FileReference class | flash.net.FileReference | The ActionScript 3.0 version inherits the addEventListener() and removeEventListener() methods from the EventDispatcher class. Dispatched events replace the event handler functions. |
|
| postData Property | flash.net.URLRequest.data | The postData property is added to ActionScript 2.0 in Flash Player 9 to send POST data with the file upload or download. In ActionScript 3.0, use the data property of the URLRequest class to send either POST or GET data. See flash.net.URLRequest.data in this language reference for details. |
|
| size Property[read-only] | flash.net.FileReference.size | Returns a uint data type instead of a Number data type. | |
| addListener() Method | flash.events.EventDispatcher.addEventListener() | In the new event model, there is no need to have a class-specific addListener() method, because the class inherits the addEventListener() method from the EventDispatcher class. |
|
