Actionscript 3 :: Setting Width And Height Of A Sprite Container?
Feb 27, 2011
I know this might seem like such an easy issue and I can't understand why I cant figure it out but none the less I can't and I've just about given up. Here's the issue:
I have a sprite container which is supposed to hold a bunch of thumbnails to videos. I am able to populate the container with all the videos and the whole works but obviously if I add a bunch of videos its going to exceed the size of the flash document so I need to add a UIScrollBar (which I did) now the scrollbars target is set to the container but isnt allowing me to scroll and if im correct this is because the container doesnt have a set height. So Im trying to set the height of this container but the second I try setting the height or even width all my thumbnails I used to be able to see are gone! It's as if the size is being set to 0 when its not I've even tried to set it to a specified size just to test and nothing.
I created a class, extended the sprite class, and now in the constructor I am trying to set the Sprite's width and height properties which are inherited from the DisplayObject. However, after I set this.width and this.height, and print the values, I get 0 for both.
What the heck is going on? When I view the livedocs I see that DisplayObject has width and height listed as public properties. I have been able to instantiate a Sprite directly, and set the width and height after it's been instantiated, so I don't get it.
package { import flash.display.*; public class ScrollBar extends Sprite {[code].....
I have a root folder that calls a container loading movie-a. The problem is that this movie-a has a red symbol that scrolls from the outside to the inside of the movie. If I loaded the movie-a by itself it wouldn't show the symbol outside but as this is inside a root... well... it shows (see image). Is there a way to set container width-height? I know I can mask it but I don't want to to that because I have other symbols flying around the movie.
Is there a way to retrieve and set the height and width of an FLV/Playback object via actionscript? I was hoping I could interact with the values via simple _height and _width properties, but that seems to offer all kinds of unexpected results in Flash (like reporting width in the thousands when the width is actually under 300, etc... height seems much closer to reality, but still off.)
[code] _buttonUnderline = new Sprite(); with(_buttonUnderline.graphics) { [/code].....
When the Tween takes place though it not only changes the width, it changes the height as if it were scaling it up in both directions. Why does this behavior take place? And how can I get it so that only the width changes? I have also tried using scaleX as the property but it does the same thing.
In a previous thread I asked a question about setting the width and height of a sprite subclass in its constructor method. One of the responses has puzzled me since I read it:
"Setting width and height only makes sense if you're adjusting the width and height of existing content, and the Chart (Sprite) has none at that point."
I don't understand that; what if you're adding children to the sprite that depend on those dimensions?
Here's a simple app which draws a red circle inside of a blue box which demonstrates my confusion as well as one other issue. The full questions are at the bottom.
Main.fla: import Box; var myBox:Box = new Box(200, 200);addChild(myBox);myBox.drawCircle();
[Code].....
Question 2: In this example, the dimensions of Circle are based on the width of its parent Box sprite. Is there a more elegant way to pass the dimensions to the circle? I ask because in my actual project (a chart) the plot area contains a lot of screen locations that must be passed around when I add new objects such as grid lines and markers and passing around the coordinates as parameters seems awfully messy. I'm just not sure how else to do it.
Why does changing the width and height of uiComp not affect the Sprite? Wouldn't UIComponent provide Sprite with a Graphics object, which limits that area where Sprite can draw?

I have a container object that i add children to. I want to change the height & width of the container without the children scaling. In this case I draw a rectangle in flash which I'll use as the container object then export for AS.
I built out a scrolling Flash application that currently resizes the browser to whatever the full-screen res of the user's monitor is... I'm kind of indifferent about it.Anyhow, I'd like to be able to set the browser size to a specific height / width instead of taking up 100% of the user's screen real-estate.
I've a slider class (SliderUI) and I'm passing slider and track images to that class as sprites.
What I'm trying to do is, passing one more image as sprite and changing its width for doing masking in slider. (It will expand or collapse as you move volume slider)
When I try to change width of sprite, it doesn't show up and I guess sprite is just container and resizing it makes it disappeared.
So how can I resize sprite with its child image (it's loaded by a Loader object by the way)?
How can I limit the size of a child container with percentage width/height of 100%?
Example:
<mx:HBox id="container" width="100%" height="100%"> <mx:HBox id="scrollContainer" width="100%" height="100%"> <!-- keep this content limited to the size of "container" -->

Apparently I can get the desired behavior if I change HBox to Canvas but I would still like to know how to accomplish this with a HBox and why it differs from Canvas.
I am working on a Flex mobile application and I want to set initial windows width and height in as3. When my app runs on Desktop, I want to detect screen resolution and set it to windows bounds, something like that this.width = Capabilities.screenresolutionX this.height = Capabilities.screenresolutionY
I want to bring an image in from a folder and then display this image in a specifically sized box.[code]So obviously I want the image loaded into a 200 x 200 box (the image is 1200x1200) and scaled proportionately. What do I need to do? The box won't resize at all.
I gave up on Flash heavy coding when it switched to AS3. Always thought it was less intuitive, longer, and a brand new language and I got tired of trying to keep up when most of my clients did not want to pay for a full flash site. But I got this client...
Here's the problem, I can load a swf into my main stage or into an MC , but I cannot find out anywhere how to set parameters or load into a level so it doesn't replace the current material or fix to a size that doesn't block my other material.[code]...
I have been given the seemingly simply task of resizing a Group container by setting width and height explicitly in response to user interaction. However, changing these values have no effect on the size of the container at all. Changing scaleX and/or scaleY will change the size of the container just fine, but this is not the behavior I am after.I have tried overriding updateDisplayList() to set a specific width and height, but this has not yielded the desired results.
I have a movieclip with the instance name of "container_mc" that I am loading a external swf file into.When I trace(container_mc._width) after the preload it returns 0.Is there any way to tell the movieclip to stay at a width of 760px and a height of 460px regardless of the content that is loaded?Reason being, I then have a function that positions the container_mc movieclip in the center of the stage based on the Stage.width/height..The only way I have been able to get this to work thus far is to have a 760px by 460px square shape, position the movieclip.. then load the content to replace the square shape however I'd rather be able to default everything without having to do that.
Is it possible to set the height of the sprite depending on the height of an textfield inside that sprite? I'm creating a box with a textfield inside it, but I want the box to be sized depending of how much text it is in the textfield..
