I have an array of Sprites on stage and want to now the rectangle that bounds them. I could do a loop and check each element's getBounds() but that could be computationally expensive.
View 1 RepliesIs it possible to make a bounding circle instead of a bounding box?The objects should bounce INSIDE the circle.I have now a bounding box outside the circle, but the objects exceeds the circle at the corners.
I was thinking of making an array of Points on the edge of a circle and when the object is < or > then do something... but that would be a lots of if/else statements.
I as this working in AS2 and need to update to AS3...shows that AS3 doesn't like sloppy coding. Here's what I need: I pull data from an XML and that works when I put the data into a dynamic text box. However, I can't seem to get the date of birth into a variable. I have some code that calcs age in years but uses a string literal that I thought I could just replace with a variable from my XML...ain't a workin'. Here's the code I have:

I've got some MC's in my library that have radiobuttons in them -- all of this created at design time -- and pull them onto the stage dynamically. My question is how do I get the selectedData from the group? The setup is like this: In a MC called pageOne, I have a group of buttons with a group name of Q1, Q2, etc. I pull the MC onto the stage like this:

Do I need instance names on each of the buttons and add listeners to all of them?
I have some code here for some falling leaves. I was wondering how it can be altered so there is a delay between a group of leaves falling and the next group falling? also to slow down at the end of the fall? [code]

How can I use displayObjects as animation frames?I have six symbols in my library I want to animate with a timer. The advantage would be the ability to change the speed of the animations, and the elimination of the messy timeline.
The only drawback is the initial setup of the objects in the library. I've tried switch/case design patterns, visible=true, and z-depth, but I can't get it to work properly. Any answers?
//setup code
var timer:Timer = new Timer(100, 20);
timer.addEventListener(TimerEvent.TIMER, countdown);
function countdown(event:TimerEvent) {

I'm working on a world builder that will load a toolkit which is represented by an xml document. The document will look similar to the following:[code]Now, I want to be able to represent this structure in flash. Vertical layout is easy enough, simply placing the elements from top to bottom. It gets mind-boggling when I need to do the following:Be able to click any folder and have all its children hidden/shown.Position the elements horizontally based on hierarchical position (indent children of folders, children of the child folders, etc)Position the folders/tools vertically when folders above and in the same "directory" are hidden.It either sounds a lot easier than it is, or I'm missing a vital and obvious step.Just to save confusion - when I make reference to "folders" and "tools", these are a MovieClip which is a simple block with text over it, like:[code]
View 1 RepliesI'm creating my first AS3 project and I've already hit my first snag, nested display objects (aka buttons and movieClips). Let's say you create a movieClip and place buttonA on frame 1 and buttonB on frame 10. You create a class for that movieClip that tells it to jump to frame X after evoking a custom method. With the same method you want to assign the buttons on that frame their functions, but you can't because Flash thinks that DisplayObject does not exist. How do you make sure all DisplayObjects for a frame have been loaded, so that you can reference them?
I have figured a way around it by using the ADDED event listener. Apparently this event is triggered every time any DisplayObject is added, whether it is nested or not. What's interesting is the number of children (numChildren) for the parent movieClip stays constant. So, this code takes advantage of that fact.

I want to create swf file without any DisplayObjects. All it has to do detect Events and save a Log. My main Application will load it as external swf file.
Is any way I can compile swf file do not extending Sprite or MovieClip?
there is a Class A, it has a timer which updates its x position periodically. So all the instance of Class A will update their own x position. There is another Class B which extends Class A and overrides the function which updates position to change y position and call the trace function.
Now what I do now is create two instance alpha1, alpha2 of Class A and other two instance beta1, beta2 of Class B.
- alpha1 is only instantiated, but not added to the stage.
- alpha2 is instantiated, and there after added to the stage.
- beta1 is only instantiated, but not added to the stage.
- beta2 is instantiated, and there after added to the stage.
- let say after few seconds, I remove alpha2 and beta2 from stage.
Now suppose the GC fires collection, who all would be collected ?
I've got another interesting Flash issue, and I was wondering if there was some weird case I had to account for. Here's the code: var c:DisplayObject; var t:Rectangle; c.width = t.width; trace(c.width, t.width); This results in output of: 0 13 I'm expecting '13 13' as the output..what would cause this to happen? It's sporadic, sometimes it'll happen, sometimes it doesn't. Is there some weird race condition I should double check for?
View 5 RepliesI am adding DisplayObjects to a Canvas using
ContentContainer.addChild(c);
Where ContentContainer is my Canvas object and c is the DisplayObject I have created at run-time. Some of these DisplayObjects also have children of there own which are added at run-time prior to the DisplayObject being added to the Canvas.
I then need to iterate over all the children of ContentContainer but the first time I do this, it says that ContentContainer has no children (i.e., ContentContainer.numChildren = 0). If I do it again tho then it is fine and returns the correct number of children. Is there something I need to call to get ContentContainer to recalculate how many children it has?
I am very new to AS3, and I'm confused about how things that would have been simple in AS2 are so complex and tricky now. For example, I want to create a bunch TextField objects that, for some reason, rise up every frame (as in : object.y-=1; ).However, I also need each TextField to reference the TextField that was created just before it.
I tried creating a variable that would hold such a reference : ThisTextField.Ref=LastTextField; but - this returns an "Access of possibly undefined property..." error. It seems I can only have custom properties on mere Objects ! This is annoying because an Object doesn't seem to accept event listeners (remember, I need them to do something every frame). Is there a way to simply set custom properties on my TextFields, without having to use custom packages ? Or is there a way to use event listeners on Objects ? I've read something about strict mode which could allow setting properties on other objects - what are the risks of turning it off ?
ActionScript Code:
private function drawMap(tile1:DisplayObject, tile2:DisplayObject):void
{
var _tile1 = tile1;
[Code].....
The idea behind this is to store custom sprites in an array and then feed the array to the drawMap function, which would use the sprites from the array to draw a map.
why Bitmaps are not considered children of displayObjects (at least from my observations, I think this is true). They themselves are displayObjects so therefore should be part of the display list. In fact, when multiple Bitmaps are in one MovieClip, it recognizes them as one child, a Shape instance. Could anyone explain this to me? I'm attaching an example with a few display objects in a movieclip.
View 8 RepliesI wanted to use dispatchEvent inside the MOUSE_OVER event of a menu item, setting the event type to a unique label which another displayobject somewhere in the display list (NEITHER a parent nor a child of the event dispatcher) would listen for, so that it could brighten. See the following lines of code:
in menu item class MOUSE_OVER handler: dispatchEvent( new MenuEvent( xml.@label.toString().toUpperCase()+"over") );
in "site button" class constructor - the thing I want to respond to your hovering over the menu by brightening (which over() does) :
addEventListener( xml.@label.toString().toUpperCase()+"over", function( e:Event ) { SiteButton( e.currentTarget ).over(); } );
It doesn't work. I screwed around with capture and bubble parameters.
how to do what I want in a simple way? I spent 2 hours already trying to figure this out.
I'm new to ActionScripts and was tasked to complete a project. I'm trying to split a big image so I can send them to a http server in chunks. I'm using a recursive function below and increasing the DisplayObjects X position on every iteration. The problem is I get the same image in every iteration and checking the encodeByteArray string value is always the same.

Since flex memory management is poor, objects once instantiated dont die very easily (even when they go out of scope), one would need to check on various properties of components. I am using one such thing to know if the screen (which is a display object) is in current view. For this I am turning on a boolean property (currently visible), and I am setting it true on show event of the display object.
What I need to know is, which event (something opposite of show, e.g left?) could be used when the screen is replaced by another display object?
Something like focusIn and focusOut from dotnet.
Or if there is some property which could directly tell me if the display object is currently in view (hasFocus doesnt seem to be giving me expected results).
How does Flash deal with elements that are off-stage?Obviously Flash doesn't actually render them (because they don't appear anywhere on-screen), but is the process of rendering them still existent, slowing down my game as much as it would if the elements were on-screen?
Or does Flash intelligently ignore elements who don't fall into a renderable area?Should I manually manage removing objects off the DisplayList and adding them back on as the exit and enter the stage, or is this going to be irrelevant?
anyway, so i'm having an issue when getting the dimensions of an image that is masked. I want to get only the dimensions of the visible image, but AS3 seems to only return the height/width of the whole image, even the areas that are not visible (because of the mask).
I could create a custom class that extends the DisplayObject and overwrites the height and width getter to return the dimensions of the mask, but my problem is that I'm placing these masked images into a container DisplayObject, and scaling that container to fit the browser window.
I'm trying to simulate some fade in/out effects in Action Script 3 programmatically, using Timer class and controlling alpha property of the specified DisplayObject in time. In general it works and looks great. As I was expecting. But after I add some more child DisplayObjects to the parent Sprite it starts to behave weirdly. Children seem to not fade at the same rate as parent object and it visually noticeable, and ugly. There seems to be a short lag after parent already started to fade out and before children actually follow. Are there any additional measures I should take to avoid that? I do alpha manipulation only on parent object. I thought that'd be logical...
View 2 RepliesI have noticed when setting a bounding box on a drag object, if you go outside the bounds of the box you have set, the mouse won't let go of the object unless you go back inside the bounds and click on it again. Is there any way to force the stopDrag if you go outside the bounds while dragging? I have tried this bit of code:

I am currently in the middle of creating a project which essentially uses Flash as a type of augmented reality system. The idea behind it is that a webcam input will capture a users hand which is placed on a white pedestal (esstially creating a complete white backbround in contrast to the hand). Create a bounding box around the hand so that objects will only move in the space taken up by the hand.
The problem I am having is wondering which functions i should use to create a bounding box that will select the space that the hand is taking up in the webcam input. I have seen the function GetColorBoundsRect but it only seems to focus on one colour and it seems to be a static function instead of one that will need to constantly create the bounding box if it moves. This isn't just a motion dection but will need to detect the hand even if it isn't moving.
This PNG image is rather large, and only a small portion is filled with pixels. Most of the image is transparant.I want to apply the effect only to the part with pixels, so I'd like to create a boundingbox around that part of the image. I need to know 4 things to do this (the way I see it...): The position of the top-most non-transparant-pixelThe position of the left-most non-transparant-pixelThe postition of the bottom-most non transparant-pixelThe position of the right-most non-transparant-pixel
View 1 RepliesIs there any simple code that will make a hittest not work of the bounding box in flash, because I've been looking for something for a while now, and can't find anything about how to do that.
View 1 RepliesI am trying to create buttons on a 45 degree angle. They are simply text. I have tried drawing different hit areas for the button, but when I publish the swf the hit area for the button is always its bounding box (so there is a huge space in the upper left and lower right corner which activates the button).
View 1 RepliesI'm trying to do collision detection for my game, but I don't necessarily like the premade methods hitTestObject or hitTestPoint just as they are. I've been searching all over the place for how to change the bounding box of a symbol, but all I found was how to get its bounding box. I'm aware of the pixel perfect collision detection code out there, but I'm looking to use bounding boxes for certain classes.
Is it possible to change the symbol's bounding box and still have that box recognized by hitTestObject or hitTestPoint? If not, I might have to write my own colllision detection code. =/
I like to know is "where, exactly, are you drawing that glyph?" The TextField class provides the methods getBounds and getCharBoundaries, but these methods return rectangles that extend far beyond the actual bounds of the whole text object or the individual character, respectively.
var b:Sprite = new Sprite();
b.graphics.lineStyle(1,0xFF0000);
var r:Rectangle = text.getCharBoundaries(4);
[Code].....
Is there any way to get more precise information about the actual visual bounds of text glyphs in ActionScript?
