1061: Call to a possibly undefined method start through a reference with static type flash.media:SoundChannel

[oliversen]

I have a problem with function start sound(startstart). I cant compile the program before getting an error.

var channel:SoundChannel = new SoundChannel();

I have 3 similar functions as NRKP1

mcButikker.btnNRKP1.addEventListener(MouseEvent.CLICK, NRKP1); 

function NRKP1(e:MouseEvent){ 

     var SoundNRKP1:Sound = new Sound(); 
     channel.stop();
     var req:URLRequest = new URLRequest("http://lyd.nrk.no/nrk_radio_p1pluss_mp3_m"); 
     SoundNRKP1.load(req);
     channel = SoundNRKP1.play(); 
}

When I added start/stop buttons for starting and stopping I got the error. But when I dont have them, and choose one of the 3 functions, it will stop the sound, and play another sound. "channel.start(); is the issue here. I have tried several ways around this but nothing seems to work.

btnStart.addEventListener(MouseEvent.CLICK, startstart);  

function startstart(e:MouseEvent){ 
     channel.start(); 
}    

btnStopp.addEventListener(MouseEvent.CLICK, stopstop); 
 
function stopstop(e:MouseEvent){ 
     channel.stop();  
}

Play the music, it seems nothing happens when I push the soundbuttons. Yeah, I have traced alot

OK! Here we go.

Basically:

- You were adding individual listeners for the buttons but was checking for clicks as the event listeners had been added to the containers. I changed it and added the listeners to the containers.

- I added names to the buttons from the list ("song0", "song1", and so on). This is needed to get the index for the current song.

- I also set the buttons' (list) mouseChildren property to false so the text inside is not selectable.

I might have done other changes, but I don't really remember now. xP

Thank you so much!

I had to take a few hours to look at the changes and correct a minor issue.

I got a issue with the channel not changing the song. After a while I understood it was the 10 first songs all playing the same song,

the traces all showed up "0" for the 10 first buttons. I changed the "name.slice" from 5 to 4, and it solved the problem Thank you so much!

I have another question to ask. Because when I scroll up/down it almost all the time choose the channel my thumb is when I remove my thumb after scrolling, if you understand. For me it looks like the scroll is too sensitive. The same happens in the emulator on the pc when using a mouse. Is there a way to code around this? Because it is kinda annoying

Yet again, thank you!
