Cue Points

Question

I have a flv which im loading in from another location (ie
its not embeded), and Im trying to create a loop point using cue
points.
I have 3 cue points: begining, loop_point, end
Basically when the playhead reaches the "end" cuepoint, I
want it to jump back to "loop_point"
Can anyone help? I have a deadline for monday to get this
finished!

Okay, I'm not exactly clear on what you just said, so I'm
going to
proceed as if you're using the FLVPlayback Component. Here's
the scoop on
using ActionScript. Just about everything is an object.
Objects are simply
"things" that behave a certain way. Movie clips are objects,
buttons are
objects ... FLVPlayback Component instances are objects --
you get the idea.
:) Objects are defined by something called classes. Think of
a class as a
given object's blueprint. You'll genearally see up to three
categories in a
class: properties, methods, and events. Properties are
characteristics an
object has, such as a movie clip's width and height. Methods
are things an
object can do, such as movie clip's ability to gotoAndPlay()
some frame.
Events are things an object can react to, such as a mouse
click.
In your case, the FLVPlayback events include a cuePoint
event. You can
see detailed information -- often including sample code --
for all the
properties, methods, and events of the FLVPlayback class by
looking up the
phrase "FLVPlayback class" in the Components Language
Reference right in the
built-in Help documentation. Component classes are listed in
this
reference, and normal classes are listed in the ActionScript
2.0 Language
Reference. In the AS Language Reference, the three categories
are combined
in each class entry, but for some reason the Components
Language Reference
separates them. But you'll see 'em when you look up the
class.
You'll want to take things slow and start with a *simple*
example.
Assuming you've added cue points through the Component
Inspector panel, your
FLV will honor those cue points during playback. Start your
journey by
looking up the cuePoint event in the "Event summary" section
for the
FLVPlayback class.
You'll see this:
var listenerObject:Object = new Object();
listenerObject.cuePoint = function(eventObject:Object):Void {
// insert event-handling code here
my_FLVplybk.addEventListener("cuePoint", listenerObject);
... which may look scary if you're not a coder, but it works
like this:
first, a variable named listenerObject is delcared as a
generic Object
isntance. This object is your "ambassador" for the
FLVPlayback instance,
which features the cuePoint event. You assign a function to a
new cuePoint
property of your generic object. This function will be
executed when any
cue point occurs. Finally, you use the addEventListener()
method to
"subscribe" your FLVPlayback instance to the generic object,
listenerObject.
Now you're "listening" for cue points.
In the above example, the instance name for your FLVPlayback
instance
must be my_FLVplybk -- but you can make it whatever you like,
as long as the
ActionScript matches the instance name.
Where it says "// insert event-handling code here," you may
want to use
a trace function ...
trace("Here's a cue point!");
... just to prove to yourself that it works. Read up in the
documentation,
and you'll see that the eventObject object received by the
function contains
valuable information about the FLVPlayback instance that
dispatches the
cuePoint event. You can trace eventObject.target, for
example, and get a
reference back to your FLVPlayback instance.
trace(eventObject.target);
That reference would let you refer to the FLVPlayback
instance and
invoke FLVPlayback methods on it, such as your various seek
options for
looping.
