as3 image load position

[jagguy999]

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.

[jagguy999]

NOt sure wheat you mean
can you give me an exampe?

[Hakan_KIRIK]

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.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");

[Hakan_KIRIK]

it works.

You need to use:

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

addChild(li);

no it doesnt work.

Here is my whole code and I get1 error with addchild

package

{

[

SWF(backgroundColor="blue", width="400",height="300")]

import flash.display.Sprite;

public class atest1 extends Sprite

{

[

SWF(backgroundColor="0x00ff00", width="400",height="300")]

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();

private var img1:String;

public function atest1(myimage:String)

{

var loader:Loader = new Loader;

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;

addChild(image);

}

}

}

var li:atest1= new atest1("ladybug.png");

var addChild(li);

[Hakan_KIRIK]

it works.

Please download my example (fla+as) and test it.

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.

[jagguy999]

i cant open fla files so could you paste it?

[Hakan_KIRIK]

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.

[jagguy999]

Hi,

no no that is not the file that is old code and I get an error with addchild in flashbuilder

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;
        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();
        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;
            addChild(image);
        }
       
    }
}var li:as2= new as2("explorer.png");
this.addChild(li);

[jagguy999]

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.
