Problem with passing an array of images to another class

Report · Nov 15, 2013

Hi,

I try to pass an array of images into a constructor of another class which then displays the images in a loop.

For some reason the stage doesn't display the images and I don't get any error messages.

This is the document class ImageRotateDemo.as :

package

{

import flash.display.Sprite;

public class ImageRotateDemo extends Sprite

{

private var images:Array;

private var rotate:ImagesRotator;

private var tAmount:Number;

public function ImageRotateDemo()

{

this.images = new Array();

this.images = ["images/image1.png", "images/image2.png", "images/image3.png"];

this.rotate = new ImagesRotator(this.images);

rotate.timeAmount = 2;

} // end constructor

} // end ImageRotateDemo class

}

This is the ImagesRotator.as class :

package

{

import flash.display.Loader;

import flash.display.LoaderInfo;

import flash.display.MovieClip;

import flash.display.Sprite;

import flash.events.Event;

import flash.events.ProgressEvent;

import flash.events.TimerEvent;

import flash.net.URLLoader;

import flash.net.URLRequest;

import flash.utils.Timer;

import fl.transitions.Tween;

public class ImagesRotator extends Sprite

{

////////////////////////////////// FIELDS ////////////////////////////////////////////

private var myLoader:Loader;

private var imgArray:Array;

private var timer:Timer;

private var myImage:MovieClip;

private var currentImg:uint;

////////////////////////////////// PROPERTIES ////////////////////////////////////////

private var _timeAmount:Number;

////////////////////////////////// CONSTRUCTOR ///////////////////////////////////////

public function ImagesRotator(img:Array)

{

this.currentImg = 0;

this.imgArray = new Array();

//this.imgArray = ["images/image1.png", "images/image2.png", "images/image3.png"]; // testing as the document class

this.imgArray = img;

// Display the first image

this.myLoader = new Loader();

this.myLoader.load(new URLRequest(this.imgArray[this.currentImg]));

this.addChild(this.myLoader);

this.currentImg++;

this._timeAmount = 2;

// Initialize timer

this.timer = new Timer(this._timeAmount * 1000);

this.timer.addEventListener(TimerEvent.TIMER, doNextTween);

this.timer.start();

} // end constructor

////////////////////////////////// METHODS ///////////////////////////////////////////

private function doNextTween(e:TimerEvent):void

{

if (this.currentImg == this.imgArray.length)

{

// Reset the timer

this.currentImg = 0;

this.timer.reset();

this.timer.delay = (0);

this.timer.start();

} // end if

this.myLoader = new Loader();

this.myLoader.load(new URLRequest(this.imgArray[this.currentImg]));

this.addChild(this.myLoader);

this.currentImg++;

this.timer.delay += (this.timeAmount * 1000); // increase the time for each image

} // end doNextTween method

////////////////////////////////// GETTERS AND SETTERS ///////////////////////////////

public function get timeAmount():Number {return this._timeAmount;}

public function set timeAmount(value:Number)

{

if(value > 0 && value < 11)

this._timeAmount = value;

else

this._timeAmount = 2 // default value in case of wrong data

} // end set

} // end ImagesRotator class

}

Like I said I don't get any errors and if I use the ImagesRotator.as as the document class and uncomment this line: //this.imgArray = ["images/image1.png", "images/image2.png", "images/image3.png"];

then everything works fine since I don't pass anything.

I'm sure I miss something about passing an array of data... ???

Thanks in advance.

Ok, sorry folks found the problem:

Forgot to add this line in the document class this.addChild(this.rotate);
