1) Player events are dispatched – This includes events dispatched by
the Timer, Mouse, ENTER_FRAMEs, URLLoader, etc…
2) User code is executed – Any code listening to events dispatched by
step 1 are executed at this stage.
3) RENDER event is dispatched – This special event is dispatched
when the user calls stage.invalidate() during normal user code
operation.
4) Final user code is executed – User code listening specifically for
step 3 is executed at this point.
5) Player renders changes to the display list.

• Tamarin is the code name used for Adobe’s
virtual machines that
• implement ActionScript 3 (AS3) [1], a flavor of
ECMAScript [11].
• JavaScript is also a flavor of ECMAScript,
however AS3 supports
