Description
System message and event handler; contains statements that run each time the playhead enters
the frame.
Place
on enterFrame
handlers in behavior, frame, or movie scripts, as follows:
•
To assign the handler to an individual sprite, put the handler in a behavior attached to
the sprite.
•
To assign the handler to an individual frame, put the handler in the frame script.
•
To assign the handler to every frame (unless you explicitly instruct the movie otherwise), put
the
on enterFrame
handler in a movie script. The handler executes every time the playhead
enters a frame unless the frame script has its own handler. If the frame script has its own
handler, the
on enterFrame
handler in the frame script overrides the
on enterFrame
handler
in the movie script.
The order of frame events is
stepFrame
,
prepareFrame, enterFrame
, and
exitFrame
.
This event is passed the object reference
me
if used in a behavior.
