Actionscript 3.0 :: Centering Stage And Background Image Using Actionscript?
Jun 13, 2010
I did a website using actionscript 2 where the content was centered on the browser window both vertically and horizontally.
e.g. [URL]
all that took was a small piece of actionscript code that i can't remember now.
Now using actionscript 3, I can't find such code anywhere, instead I am guided towards using dreamweaver and css which seems like a nightmare for me to achieve. Such a fundamental thing should be possible with minimum effort surely?
Also, I have a similar problem where I'm trying to repeat tile or just add a textured background behind the stage. This also seems like I'm having to use html/css to achieve. I'd rather just use flash if possible??

I'm told that the following chunk of script will center the stage on resize, but not knowing much of anything about actionscript,
myListener = new Object(); myListener .onResize = function () { ... } Stage.addListener( myListener ); // later ... Stage.removeListener( myListener );

i've created a rotating banner with images and wanted to increase the stage size so i can put an opaque larger image in the background and have the other images rotate on top of it. when i made the stage larger i'm having difficulty selecting the other photos so i can center them back on the on the stage. i was able to get the first image centered but i only see the outline of the other images.

I have a menu that is driven by AS3 and XML, I am trying to simply put a background image behind the menu but when I import a jpg and place onto the stage the background is always in front of the menu? The menu is an external AS file and is not on the timeline. What I can do to get the image to sir behind the menu?

everything is working well with the exception of the background image/stage. Whenever I preview it in a browser, the site gets stuck in the upper left corner. I need it to automatically resize according the to viewers browser size. How do I do this? From what I've seen online, it involves possibly putting everything in a movieclip, which I can do, I just don't know how to proceed from there.

I'm writing a web based flash app that's written entirely in AS3. I have objects on the screen as part of a GUI. I would like the user to be able to resize the window, or make it full screen. I would like everything to auto-scale with the resize, but also remain in the same relative position on the stage.

I'm wondering if I can lower the transparency of any skin in QuickBox2D, I have searched the documentation but I can't find it. Transparency value or filters(Multiply/Overlay). Example: If I create a movieclip, and make it overlayed and then call it through a QuickBox2D, it will become invisible. I want to blend skins with the stage background image. [URL]

I have a code for a page I am using and I would like to add a background and have it resize with the screen like the rest of the page. I have created a movie button named "pic" with the image in it but I don't know how to write the code and place it in the existing AS3 code file.how to place the code like i was in 3rd grade, that would be great. Here is the existing code.

I have been struggling with this with CS4 and CS5. I am working on an animation with a couple of characters comprised of several pngs I converted to symbols. When one characters symbols overlap another characters the swf file shows the stage color rather than the background image I have placed in the file. I can publish it as an html with the option of playing it windowless transparent and it will remove this problem. But I would like to just be able to play the swf file without this issue.

I would like to have a project where the background fits the whole window (can squeeze) and the content is automatically resized and centered; keeping its ratio.Auto-Resizing and Centering your Content But here's my problem :
My main project is 1400*900px.
My MC to handle is 1000*680px.
I load an external SWF in that MC (with addChild).This external SWF is 1000*680px too (same size than parent).I have a lot of clips in my external SWF and some of them are "out" the project zone.So when I load it in my MC; the MC is no more 1000*680 but more.I thought that what was outside didn't matter; but it seems that flash do not ignore what is out.So, when I use the code to resize/recenter the MC; it broke as it do not center as it should.I did try to use masks but it do the same.

So I am working on a full screen website, and background_mc I want to be centered and scaled 100% to the stage. But I also do not want the image to loose it's proportions. Here is my code so far, it is only seeming to center the movieclip:
Code: Select allfscommand ("fullscreen", true);
Stage.scaleMode = "noScale";
Stage.align = "TL";

When I open a new document in flash, the stage is in the top left corner of my screen and I cannot figure how to center it in the middle. I cannot go to the left or above the stage which is making it very difficult to work with as I cannot access those areas.

I have a movieClip that starts out a a specific scale. I then tween the images properties and as it tweens it also scales again. What I'm trying to do as it tweens and scales its obviously changes the width and height of the movieClip. So I'm trying to constantly keep the clips position in the center of the stage.
I'm using tweenMax and I tired an update event so I could keep checking the width and height of the clip as it scales and then using this code to center it but it doesn't seem to be centering the image. On other thing to note is my MovieClip is using its top left corner as the registration point.

I've come across a new snag to a previous project. I'm not quite sure why, but when the full image is loaded to the stage, it is not centering it properly. The trace of fullLoader returns "0" for the width and height of the full-sized image, and I'm not quite sure how to pass the necessary information into the showPicture function so that it correctly centers the image. I tried tracing the content of fullLoader and got an error message.[code]

I'm heaving trouble centering the preloader on the center of the stage. The preloader is basically a rotating oval shape.
so, below is the code that for some reson puts the circle in the top left corner...
Code:
stop();
var circle:LoadCircle = new LoadCircle();
var circle_WIDTH:Number = circle.width;
[Code]....
meaning... the stage is not static, but it dynamically shrinks and expands to the size of the oval preloader...
how to make the stage "static" so that when I set the size in the document properties, centering an object in AS3 will stick to it?

I'm having trouble with the positioning of objects within the NativeWindow. So my code below creates a NativeWindow, and then draws a rectangle and adds it to the stage of the NativeWindow. I can't seem to have the rectangle centered in the window. I've tryed playing with the stage scale mode, and align properties. By default the align should be center, but it doesn't appear to be the case. The rectangle seems to be drawn from somewhere between the center and top left of the window. I've also drawn a rectangle onto the main app window using identical code.
Code:
import flash.display.NativeWindowInitOptions;
import flash.display.NativeWindow;
var NWIO = new NativeWindowInitOptions();
[code]....
Left window is the main app, and the right window is the NativeWindow.

I would like to call up images from myXML and I would like to center them on the stage. Each object is a different size therefore I can't place them to a set _x position. Hopefully someone may have the answer.... here's the function that will call up the firstimage:
function firstImage() {
if (loaded == filesize) {
var myHoriTween:Tween = new Tween(content_mc, "_x", normal, 0, 480, .75, true);
content_mc.loadMovie(image[0]+".jpg", 1);
content_mc_num();
}
The highlighted '480' is the number i would like to replace to center. I'm not being to vague with this request, otherwise i'll offer more information.

I have a picture of a mine which is nested within an object, nested within another object. Now what I want it that on the keypress of shift, I created mine image at the same position of the tank. The issue is that the main object that is nesting the mine moves, thus not creating at the the center, rather on that position of the object.
Here are how my images go by instance names;
1. Tank Stays in the center
//////
/////
1. Land (moves) -- 2b. map -- 3b. All objects that hitTest

2a. Objects

3b. All the objects that don't get hit (in here is mine.)

I have a movieclip on the stage which has the dimensions 400x400.I currently load images,and add them to this component.Each image is a different size. At this moment in time, they are placed at position 0,0 within the movieclip container.Some of the code looks like
var data:XML;
var total:Number;
var url_list = new Array();[code]....
Is there anyway I could get the loaded images placed at the center of the movieclip container.I dont know if I have to do something like subtract the images width and height from the containers width and height, and then divide by 2?

I want to center a big movieclip (1400 px wide) on my stage on stage resize. This big movieclip moves to the right on certain events so I can't use code like this:
currentPage.x = ((stage.stageWidth/2) - (currentPage.width/2))
Is there a way to maybe use its offset from 0 (the left side of the stage 'viewport') and use that offset in centering? The movieclip only changes in x.

I'm currently working in Flash 8 with Actionscript 2.0.
I've been trying different alternatives and none of them are working. I've even posted here previously and tried a few things but I haven't quite resolved my centering to stage problem. Some of you may have already read pieces of this from another post.
I have a landscape that functions sort of like a 360 vr tour. The main movie clip directly on the stage is labeled, "mainMovie", and within it is another movieclip labeled, "singleStrip".
To simulate the 360 vr tour, there's script inside, "mainMovie" to duplicate "singleStrip". Also, inside the "singleStrip" movie clip, I have different elements appearing through the landscape, in this case, we'll use letters as an example. The letters A - Z are sitting on the landscape throughout the entire "singleStrip" movie clip.
Everything rotates fine with the script that's placed some sensitive area movie clips that are placed on the root level. When you place your mouse pointer to the left edge of the stage, the landscape shifts left, when you move the mouse pointer to the right edge, the landscape shifts right, (or vice versa, I can't remember).
The problem I'm having is for the letters that are in view on the stage, I want the user to be able to "click" on them and then that letter zoom up to the center of the stage, (through the "x" coordinate). I'm having difficulty with this since the letter movieclips, (example, "letterA"), are within the "singleStrip" movie clip, which sits inside the "mainMovie" movie clip, which are both constantly moving and their x position continues to change.
I've been using the tween class in order to animate them with easing and it's usually the "endx" variable that I'm having trouble because I don't know how I can match it up to the center of the stage, whether it's a "endx = stage.width._x /2; " or something else. Here's an example of some of the [code]...

i am trying to get an empty movieclip to center after a jpg loads into it. the images load, but they don't center. my first attempt (using loadMovie) would read the size too quickly and would only center after a second click. i thought using a MovieClipLoader would work, but my leftEdge always returns 350. i'm getting a 0 value for _width.
on a related topic, i want to apply a DropShadowFilter to the same empty movieclip.i haven't tried it with the MovieClipLoader, but it didn't work using loadMovie. any ideas on that? if i have to, i can create a generic dropshadow and position and scale it accordingly, but again, i will need to be able to read the size and position of the empty movieclip.
Code:
var mcl:MovieClipLoader = new MovieClipLoader();
var mclListener:Object = new Object();[code]...
