Hey guys,
I’m currently trying to load a gallery.swf into my mainmovie.swf. But when I try this I get this ERROR #1009:
TypeError: Error #1009: Der Zugriff auf eine Eigenschaft oder eine Methode eines null-Objektverweises ist nicht möglich.
at Handle()
at flash.display::Sprite/constructChildren()
at flash.display::Sprite()
at flash.display::MovieClip()
at Gallery()
TypeError: Error #1009: Der Zugriff auf eine Eigenschaft oder eine Methode eines null-Objektverweises ist nicht möglich.
at Gallery()
The gallery.swf consists of 3 classes:
The gallery.as:
package
{
import flash.display.MovieClip;
import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.events.*;
public class Gallery extends MovieClip
{
private var imagesToShow : Number = 4;
public var spaceBetween : Number = 20;
public var defaultWidth : Number = 195;
private var backend : String = 'backend.php';
private var xmlLoader:URLLoader = new URLLoader();
private var xdata : XML;
public var images : Array = new Array();
private var orgImgId : Number;
private var skipTo : Number = 0;
private var loaded : Boolean = false;
public var imagesClip : MovieClip = new MovieClip();
public var stageWidth : Number;
public function Gallery() : void
{
stageWidth = stage.stageWidth;
theHandle.addEventListener( "sliding", slide );
imagesClip.y = 180;
addChild( imagesClip );
xmlLoader.load( new URLRequest( backend + "?" + new Date().valueOf() ) );
xmlLoader.addEventListener( Event.COMPLETE, loadImages );
}
private function loadImages( _e : Event ) : void
{
xdata = new XML( _e.target.data );
var i : Number = 0;
for each( var img:XML in xdata.img )
{
images* = new Img( img, this );
images*.x = 200 * i;
images*.id = i;
i++;
}
goTo( 0 );
}
private function slide( _e : Event ) : void
{
var percent : Number = ( theHandle.goToX - slider.x ) / ( slider.width - theHandle.width );
var imgId : Number = Math.round(percent * ( images.length - 1 ));
goTo( imgId );
}
private function goTo( imgId : Number ) : void
{
var direction : Number;
if ( orgImgId != imgId )
{
if ( imgId > orgImgId ) direction = 1;
else direction = -1;
for ( var i : Number = - Math.floor(imagesToShow/2); i <= Math.floor(imagesToShow/2); i++ )
{
if( imgId + i < images.length && imgId + i >= 0 ) images[imgId + i].makeActive( i, direction );
}
for( var j : Number = 0; j < imagesClip.numChildren; j++ )
{
var tile : Img = imagesClip.getChildAt(j) as Img;
if ( tile.id < imgId - Math.floor(imagesToShow/2) || tile.id > imgId + Math.floor(imagesToShow/2) ) tile.deActive( direction );
}
countTxt.text = imgId + 1 + "/" + images.length;
}
orgImgId = imgId;
}
}
}
The handle.as:
package
{
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.events.Event;
public class Handle extends MovieClip
{
public var goToX : Number = x;
private var slider : MovieClip = MovieClip(parent).slider;
private var mousePos : Number = 0;
public function Handle() : void
{
buttonMode = true;
addEventListener( MouseEvent.MOUSE_DOWN, moveHandle );
stage.addEventListener( MouseEvent.MOUSE_UP, stopHandle );
}
private function moveHandle( _e : MouseEvent ) : void
{
mousePos = mouseX;
stage.addEventListener( MouseEvent.MOUSE_MOVE, followHandle );
}
private function stopHandle( _e : MouseEvent ) : void
{
stage.removeEventListener( MouseEvent.MOUSE_MOVE, followHandle );
}
private function followHandle( _e : MouseEvent ) : void
{
var newPos : Number = stage.mouseX - mousePos;
var orgX : Number = x;
if ( newPos < slider.x )
goToX = slider.x;
else if ( newPos > (slider.x + slider.width) - width )
goToX = (slider.x + slider.width) - width;
else
goToX = newPos;
x = goToX;
if( goToX != orgX ) dispatchEvent( new Event( "sliding", true ) );
}
}
}
The img.as:
package
{
import flash.display.MovieClip;
import flash.display.Loader;
import flash.display.Bitmap;
import flash.text.TextField;
import flash.events.Event;
import flash.net.URLRequest;
import flash.events.*;
import fl.transitions.easing.*;
import flash.text.TextFormat;
import gs.TweenLite;
import fl.motion.easing.*;
import flash.text.TextFieldAutoSize;
public class Img extends MovieClip
{
public var active : Boolean = false;
public var id : Number;
private var src : String;
public var imageLoader:Loader = new Loader();
private var orgWidth:Number = 0;
private var orgHeight:Number = 0;
private var main : Gallery;
private var deactivating : Boolean = false;
public function Img( load : String, m : Gallery ) : void
{
orgWidth = width;
orgHeight = height;
main = m;
src = load;
alpha = 0;
}
public function loadImage() : void
{
if ( numChildren < 3 )
{
imageLoader.load( new URLRequest( "img/" + src ) );
imageLoader.contentLoaderInfo.addEventListener( Event.COMPLETE, displayImage );
}
}
private function displayImage( _e : Event ) : void
{
if ( main.images[id + 1] != null && !main.images[id + 1].parent ) main.images[id + 1].loadImage();
Bitmap( imageLoader.content ).smoothing = true;
imageLoader.x = main.spaceBetween/2 - ( orgWidth /2 );
imageLoader.y = main.spaceBetween/2 -( orgHeight /2 );
addChild( imageLoader );
var descr : TextField = new TextField();
descr.text = src;
descr.y = ( orgHeight /2 ) - 27;
descr.x = 10 - ( orgWidth /2 );
descr.autoSize = TextFieldAutoSize.LEFT;
descr.embedFonts = true;
var format : TextFormat = new TextFormat("cFont", 15, 0);
format.color = 0x5B4846;
descr.setTextFormat( format );
addChild( descr );
}
public function makeActive( position : Number, direction : Number ) : void
{
deactivating = false;
if ( parent == null )
{
x = ( direction == 1 ? main.stageWidth + main.defaultWidth * 2 : - main.defaultWidth * 2 );
alpha = 0;
main.imagesClip.addChild( this );
}
visible = true;
if ( numChildren < 3 ) loadImage();
parent.setChildIndex(this, ( parent.numChildren-1 ) - Math.abs( position ) );
var extra : Number = Math.round( position * ( main.defaultWidth + main.spaceBetween ) );
var newX : Number = ( Math.round( ( main.stageWidth / 2 ) /* - ( main.defaultWidth / 2 )*/ ) + extra );
flyTo( newX, false, (position == 0 ? 1.2 : 1 ) );
}
public function deActive( direction : Number ) : void
{
if ( ! deactivating )
{
active = false;
var moveTo : Number = ( direction != 1 ? main.stageWidth + main.defaultWidth * 2 : parent.x - main.defaultWidth * 2 );
flyTo( moveTo, true );
deactivating = true;
}
}
private function flyTo( newX : Number, removeAfter : Boolean, scale : Number = 1 ) : void
{
var tweeningOptions : Object = new Object;
tweeningOptions.x = newX;
if ( removeAfter )
{
tweeningOptions.ease = Linear.easeIn;
tweeningOptions.alpha = 0;
tweeningOptions.scaleX = tweeningOptions.scaleY = 0.3;
tweeningOptions.visible = false;
}
else
{
tweeningOptions.scaleX = tweeningOptions.scaleY = scale;
tweeningOptions.rotation = (Math.random() * 20) - 10;
tweeningOptions.ease = Back.easeOut;
tweeningOptions.alpha = 1;
}
TweenLite.to ( this, 0.4, tweeningOptions );
}
private function motionEnd () : void
{
visible = false;
}
}
}
Therefore I read through some threads and found Event.ADDED_TO_STAGE as a solution… But I’m pretty new to this and don’t realy know how to do this…
Could you help me out?
Thank you!
