Question

NetStream() and CuePoints

Hi,

Iv recently started using flash again after a few years of neglect (I finally have a job that pushes me!) and I'm finding I'm a little rusty...

Very simply Im having some issues creating reactions to CuePoints when using NetStream();

I can get what I want to work when the video is embedded directly onto the stage by using the following code:

vid.addEventListener(MetadataEvent.CUE_POINT, cp_listener);


function cp_listener(eventObject:MetadataEvent):void {

     obj = eventObject.info.parameters;

     for (key in obj) {

          if (key == "CuePointName1") {

               // then do whatever I want to happen when CuePointName1 is reached in the video

          }

}

But when I translate it over to work with NetStream it doesn't work:

// START NETSTREAM


var nc:NetConnection = new NetConnection();

nc.connect(null);

var ns:NetStream = new NetStream(nc);

ns.client = this;

ns.play("video.flv");

var vid:Video = new Video();

vid.attachNetStream(ns);

addChild(vid);



// CUEPOINT LISTENERS

function onCuePoint(infoObject:Object):void {

     for (key in infoObject) {

          trace(infoObject["name"]);

          if (infoObject["name"] == "CuePointName1") {

               // then do whatever I want to happen when CuePointName1 is reached in the video

          }

     }

}

The trace statement is returning the name of the CuePoint correctly, but 4 times like this:

CuePointName1

CuePointName1

CuePointName1

CuePointName1

Witch I assume is why the if statement isn't picking it up.

Any help will be most appreciated!

Thanks

Ross

Because info object has four parameters (name, parameters, time, and type) and you loop through them. Also, why do you use "name" as a string when you can just do infoObject.name?

In any case do that and you will see the key name and value:

function onCuePoint(infoObject:Object):void {
     for (var key:String in infoObject){
          trace(key, infoObject[key]);
     }
}

Hi Andrei1,

Thanks for your help and for improving my script, but i'm essentially no further forwards...

How do I compare only the name value and ignore the other 3? Because if I understand you correctly (and testing shows):

if (infoObject.name == "CuePoint1") {
     // what to do when CuePoint1 is reached
}

Is the same as:

if (infoObject["name"] == "CuePoint1") {
     // what to do when CuePoint1 is reached
}

Just slightly better coding.

Thanks for your help so far.

Excuse my stupidity, I really am rusty!

The reason I was having problems was that I had simply attached the video directly to the stage (ontop of all the other objects) so I simply couldn't see what was happening!

By creating n empty movie clip on the very back layer and loading the video into it like this:

vidholder.addChild(vid);

it sorted it.

Sorry for wasting your time!
