ActionScript 2.0 to 3.0

Miscellaneous

This section describes miscellaneous changes to the ActionScript language.

MovieClip

MovieClip has been replaced by Sprite as the parent class of the base object for Flex controls, 
UIComponent. 

The following table lists changes to methods of MovieClip: 

The drawing methods such as 

moveTo()

 are now accessed via the 

graphics

 property of the 

MovieClip object. To use them you must import the flash.display.* package. 

ActionScript 2.0 method ActionScript 3.0 equivalent

beginMeshFill()

The 

beginMeshFill()

 method has been removed. There is no 

ActionScript 3.0 equivalent.

swapDepths()

Target paths are not supported in ActionScript 3.0. Instead, 
you can specify depth as integer depth value, or rewrite your 
code using ActionScript 3.0 Sprites instead of MovieClips.

setMask()

Target paths are not supported in ActionScript 3.0. Instead, 
you can specify the mask as a DisplayObject, or rewrite your 
code using ActionScript 3.0 Sprites instead of MovieClips. 

loadMovie()

The method (GET or POST) optional argument to the 

loadMovie()

 method is not supported in ActionScript 3.0. 

getURL()

The 

getURL()

 method has been deprecated. You should 

instead use the 

navigateToURL()

 method. For more 

information, see the Flex 2 Developer’s Guide.

loadMovieNum() 

The 

loadMovieNum()

 method is no longer supported in 

ActionScript 3.0. To achieve similar functionality, rewrite your 
code to use ActionScript 3.0 Sprites instead of ActionScript 
2.0 MovieClips. 

loadVariables()

The 

loadVariables()

 method is not supported in ActionScript 

3.0.
