[RESOLVED] AS3: looping video error message

[dennisRep]

Here is my site sans looping video: http://fantasy-animation.com

I am setting my video up to loop. I used the following code:

__________________________________________________ ___________

var vid:Video = new Video();
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
ns.addEventListener(NetStatusEvent.NET_STATUS, ns_onPlayStatus);
addChild(vid);
vid.attachNetStream(ns);
ns.play("main.flv");

/////loop video
var count:Number = 0;
function ns_onPlayStatus(event:NetStatusEvent):void {
trace(event.info.code);
if (event.info.code == "NetStream.Play.Stop") {
if(count == 0){
ns.play("main.flv");
count++;
trace("now what?");
} else {
ns.seek(0);
}
}
}

__________________________________________________ ___________

It works but returned this error message:
__________________________________________________ ___________

NetStream.Play.Start
NetStream.Buffer.Empty
NetStream.Buffer.Full
Error #2044: Unhandled AsyncErrorEvent:. text=Error #2095: flash.net.NetStream was unable to invoke callback onMetaData. error=ReferenceError: Error #1069: Property onMetaData not found on flash.net.NetStream and there is no default value.

__________________________________________________ ___________

How can I change the code to eliminate this message?

Thanks in advance.

netStream.addEventListener(AsyncErrorEvent.ASYNC_E RROR, doAsyncError);
netStream.addEventListener(IOErrorEvent.IO_ERROR, doIOError);

Also, register for Metadata:

var clientObject:clientObject = new Object();
clientObject.onMetaData = doMetaData;

function doMetaData(infoObject:Object):void {

}

[dennisRep]

var clientObject:clientObject = new Object();

type was not found or was not a compile time constraint: clientObject

[Beathoven]

var clientObject:Object = new Object();

[dennisRep]

Thanks Beathoven,

The following statements contain variables that have not been defined?

netStream.addEventListener(AsyncErrorEvent.ASYNC_E RROR, doAsyncError);
netStream.addEventListener(IOErrorEvent.IO_ERROR, doIOError);

access of undefined property netStream,
access of undefined property doAsyncError,
access of undefined property doIOError

[regbolD]

var clientObject:clientObject = new Object();

type was not found or was not a compile time constraint: clientObject

Sorry, I misspelled it, but

Beathoven corrected it.

Thanks Beathoven,

netStream.addEventListener(AsyncErrorEvent.ASYNC_E RROR, doAsyncError);
netStream.addEventListener(IOErrorEvent.IO_ERROR, doIOError);

access of undefined property doIOError

Yes, I didnt wrote the whole thing.
Open flash help to see in details.

netStream you defined as ns, and these functions need to be defined as well:

_netConnection.addEventListener(SecurityErrorEvent.SECURITY_ERROR, doSecurityError);        _netConnection.addEventListener(NetStatusEvent.NET_STATUS, doNetStatus);
_netConnection.addEventListener(IOErrorEvent.IO_ERROR, doIOError);
_netStream.addEventListener(AsyncErrorEvent.ASYNC_ERROR, doAsyncError);
_netStream.addEventListener(NetStatusEvent.NET_STATUS, doNetStatus);
_netStream.addEventListener(IOErrorEvent.IO_ERROR, doIOError);

private function doSecurityError(e:SecurityErrorEvent):void {
            
        
}
        
private function doIOError(e:IOErrorEvent):void {
            
        
}
        
private function doAsyncError(e:AsyncErrorEvent) {
            
        
}

I have posted this question because I don't know AS3 very well. I don't know anything about the code you are posting. Posting incomplete answers is confusing me more than I was at start. I suspect your last post is incomplete as well as I am getting more errors with more undefined properties.

I appreciate your help, but incomplete answers don't help me.

[Beathoven]

nc.addEventListener(SecurityErrorEvent.SECURITY_ER ROR, doSecurityError); nc.addEventListener(NetStatusEvent.NET_STATUS, doNetStatus);
nc.addEventListener(IOErrorEvent.IO_ERROR, doIOError);
ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, doAsyncError);
ns.addEventListener(NetStatusEvent.NET_STATUS, doNetStatus);
ns.addEventListener(IOErrorEvent.IO_ERROR, doIOError);

private function doSecurityError(e:SecurityErrorEvent):void {


}

private function doIOError(e:IOErrorEvent):void {


}

private function doAsyncError(e:AsyncErrorEvent) {


}

[dennisRep]

Ok, thanks.

When I post the script as is, I get message 1013: The private attribute may be used only on clas property definitions.

If I remove 'private' from the code, 'doNetStatus' is undefined.

Looks like we are almost there. Are you over me yet?

[Beathoven]

Sorry I just quickly skimmed over reg's code.

If you are not using classes, then you can remove the private statements. They are used within classes to make the functions only available within that class. They are irrelevant to timeline coding.

The reason doNetStatus is undefined is because you need to create the function.

The way this works if you look at this statement:

nc.addEventListener(NetStatusEvent.NET_STATUS, doNetStatus);

This is what it says:

Take the object nc (You created this object a few lines above and made it an object of "NetConnection" type) and add an event listener to it. Event listener will listen for events that are dispatched from that nc object.

If the nc object receives an event of type "NetStatusEvent.NET_STATUS", then the program needs to execute the function "doNetStatus".

Thinking you would grasp the concept, reg gave you a few function definitions and figured you could fill in the blanks. This is how you would define the doNetStatus function:

function doNetStatus(e:NetStatusEvent):void
{

}

What this does is say create a function named "doNetStatus". This function will recieve an event of type "NetStatusEvent" as an argument and assign the value of that "NetStatusEvent" to the variable "e". (ie: (e:NetStatusEvent)). The last part, ":void" means the function will not return anything, there will be no return statement within the brackets. ( {} ).

So for this whole piece of code to work, it needs this:

nc.addEventListener(SecurityErrorEvent.SECURITY_ER ROR, doSecurityError);
nc.addEventListener(NetStatusEvent.NET_STATUS, doNetStatus);
nc.addEventListener(IOErrorEvent.IO_ERROR, doIOError);
ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, doAsyncError);
ns.addEventListener(NetStatusEvent.NET_STATUS, doNetStatus);
ns.addEventListener(IOErrorEvent.IO_ERROR, doIOError);

function doSecurityError(e:SecurityErrorEvent):void {


}

function doNetStatus(e:NetStatusEvent):void {

}

function doIOError(e:IOErrorEvent):void {


}

function doAsyncError(e:AsyncErrorEvent) {


}

Thank you so much for taking the time to not only help me with the code but EXPLAIN it as well. I am a digital artist not a developer, so I am a beginner level at best when it comes to code. Just giving me the code is great, but I would like to learn what the code is doing line by line as well.

I have made the changes and everything works great.

[dennisRep]

It would be a great policy to follow Beathoven's example when helping others with code. It would be very helpful to comment out each line of code so we can understand what it does. After all, I think most of us want to learn it, not just copy and paste it.

[Beathoven]

Please mark the thread resolved. (Top Right, Thread Tools, Mark Thread Resolved)

[dennisRep]

I did.
