MovieClip.onEnterFrame
Availability
Flash Player 6.
Usage
my_mc.onEnterFrame = function() {
// your statements here
}
Parameters
None.
Returns
Nothing.
Description
Event handler; invoked repeatedly at the frame rate of the SWF file. The actions associated with
the
enterFrame event are processed before any frame actions that are attached to the affected
frames.
You must define a function that executes when the event handler is invoked. You can define the
function on the Timeline or in a class file that extends the MovieClip class or is linked to a symbol
in the library. For more information, see “Assigning a class to a movie clip symbol” in Using
ActionScript in Flash.
Example
The following example defines a function for the onEnterFrame method that sends a trace()
action to the Output panel:
my_mc.onEnterFrame = function () {
trace ("onEnterFrame called");
};
