as3 image load position

Sep 29, 2010 1:38 AM

q1)where do i set screen dimensions?
q2)how can i set the images position on screen without using the imageLoaded function because I need to display many images and dont want to create this imageLoaded for every image.

package
{
    import flash.display.Sprite;

    public class atest1 extends Sprite
    {
        import flash.display.Bitmap;
        import flash.display.Loader;
        import flash.display.Sprite;
        import flash.events.Event;
        import flash.net.URLRequest;

        public function atest1()
        {
            var loader:Loader = new Loader;

            loader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoaded);
            loader.load(new URLRequest("ladybug.png"));
            //loader.x=200;
            //loader.y=100;
        }

        private function imageLoaded(event:Event):void
        {
            var image:Bitmap = new Bitmap(event.target.content.bitmapData);
            addChild(image);
            //image.x=200;
            //image.y=10;
        }

}
}

var li:atest1= new atest1 ()

You can use a double loop and increase
x and y positions for every loader.

here is an example (with just one loop):

var array:Array=["url1","url2","url3"]; // u should fill that array somehow with more data...

var wid:Number=150;
var hei:Number=100;
var x_counter:int=0;
var y_counter:int=0;
var columns:int=4;

function loaderFunc():void{

for (var i:Number = 0; i < array.length; i++){

var thumb_url = array[i].toString();

var thumb_loader = new Loader();

thumb_loader.load(new URLRequest(thumb_url));

thumb_loader.x = (wid+10)*x_counter;

thumb_loader.y = (hei+10)*y_counter;

addChild(thumb_loader);

if (x_counter+1 < columns){

x_counter++;

} else {

x_counter = 0;

y_counter++;

}

}

}

An easier way is using paramters in the constructors but it doesnt work??
why does this code fail to load anything without an error?

package

{

import flash.display.Sprite;

public class atest1 extends Sprite
{

import flash.display.Bitmap;

import flash.display.Loader;

import flash.display.Sprite;

import flash.events.Event;

import flash.net.URLRequest;

import flash.text.*;

private var myy:int;

private var myx:int;

private var txt1:TextField = new TextField();

public function atest1(x:int,y:int)
{

var loader:Loader = new Loader;
myx=x;
myy=y;
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoaded);
loader.load(
new URLRequest("ladybug.png"));
txt1.text =
"Text1";
addChild(txt1);

import flash.text.*;

}

private function imageLoaded(event:Event):void
{

var image:Bitmap = new Bitmap(event.target.content.bitmapData);

image.x=myx;
image.y=myy;
addChild(image);
}

}
}

var

li:atest1= new atest1(10,200); //doesnt work

You will need again a loop if you wanna use more than one image (and calculate each time x and y positions)

I thought AS3 was OOP?
I cant pass paramters in constructors so I need to pass them when an imge is loaded .
If I need to load 3 images how do i do this in as3 without constructors????

var li:atest1= new atest1("img1");
var li:atest1= new atest1("img2");
var li:atest1= new atest1("img3");

it works.
You need to use:

var li:atest1= new atest1(10,200);
addChild(li);

I have flashbuilder and
my code has changed a little since then as you can see.
Could you try my current code where I want to load a file by passing the filename in the constructor?

Might be flashbuilder is no good.

I did it before:

codes in fla file:

var aa:atest1=new atest1(33,44);
addChild(aa);

The .as file is in the Rar file and with Flashbuilder you can open it.

What I wanted to do is pass the string of the image to display

package

    import flash.display.Sprite;

    public class as2 extends Sprite
    {

        import flash.display.Bitmap;
        import flash.display.Loader;

        private var myx:int;
        private var txt1:TextField = new TextField();
        private var img1:String;

        public function as2(myimage:String="")
        {

            var loader:Loader = new Loader;
            this.img1=myimage;
            myx=100;
            myy=100;
            loader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoaded);
            loader.load(new URLRequest(img1));



        }

        private function imageLoaded(event:Event):void
        {
            var image:Bitmap = new Bitmap(event.target.content.bitmapData);

            image.x=myx;
            image.y=myy;

I suspect my flashbuilder isnt working so could some one try my code on the next post above and just load any image.

I spent hours on this and all I need is someone to verify if this does work.
Then I can look at my installation.
