Features not available in Flash Lite 1.x
ActionScript
Because Flash Lite player is based on an older version of Flash Player, it does not support all
the programming features available in more recent releases of Flash Player or other
programming languages that you might be familiar with. This section discusses programming
features not available in Flash Lite 1.x ActionScript and available alternatives and
work-arounds.
User-defined functions
Flash Lite 1.x does not support the ability to define and call
custom functions. However, you can use the
call()
function to execute code that resides on
an arbitrary frame in the timeline. For more information, see “Using the call() function to
create functions” on page 13 .
Native arrays, objects, or other complex data types
Flash Lite 1.x does not support
native array data structures or other complete data types. However, you can emulate arrays
using pseudo-arrays, a technique that involves using the
eval()
function to dynamically
evaluate concatenated strings. For more information, see “Emulating arrays” on page 11 .
Runtime loading of external image or sound files Unlike the desktop version of Flash
Player, Flash Lite 1.x ActionScript cannot load external JPEG files or MP3 files. In Flash Lite
1.1 you can use the
loadMovie()
function to load external SWF files. For more information,
see “Loading external SWF files” on page 22 .
