The class or interface 'flash.utils.ByteArray' could not be loaded.

Question

Hi there..

I am a total Flash newbie. I just installed Flash CS5 and ran this code.

import flash.display.BitmapData
import flash.geom.Matrix
import com.adobe.images.JPGEncoder;
import flash.net.FileReference;
import flash.utils.ByteArray;

//get the default camera
//change your Default camera using the Flash Player Settings.
cam=Camera.get()
//this event is called whenever permission to access the local camera, is accepted or denied by the user
cam.onStatus=function(e)
{
    //if we are given permission
    if(e.code == "Camera.Unmuted")
    {
        //start the application
        initialize()
    }
    else
    {
        System.showSettings(3)
    }
}

var snapshot:BitmapData=new BitmapData(cam.width,cam.height);

function takeSnapshot()
{   
    var i:Number=1;
    var fileRef:FileReference = new FileReference();
    snapshot.draw(cam,new Matrix());
    //saveImage();
     var encoder:JPGEncoder = new JPGEncoder();
     var ba:ByteArray = encoder.encode(bitmapData);
     fileRef.save(ba,"capture"+i+".jpg");
     i++;
}


//if there are no Cameras
if(cam == null)
{
    System.showSettings(3)
}
else
{
    cam.setMode(1024, 768, 30);
    cam.setQuality(10000,0);
    output.attachVideo(cam);
    setInterval(this,"takeSnapshot",100);
}

Then on exporting to SWF I get the error: The class or interface 'flash.utils.ByteArray' could not be loaded.

Any help here ?

Are there any AS3 settings I need to change ?

Answer 1

Sounds like you're not exporting using AS3, when you got to export be sure to select "Actionscript 3" as the language. I just tried it using CS3 (but I doubt CS5 changed anything in this regard), and everything worked fine.

To change a project to AS3 (in CS3): Go to File > Publish Settings... > Click the flash tab > Change ActionScript version to "Actionscript 3.0".
