ActionScript 3.0 :: Swap Children Of Stage From Inside A Child?
Apr 26, 2008
I have 9 movie clips which are all of the same object, they get larger or smaller as the mouse gets closer to their respective centers. The functionalilty for this is in an AS3 class file that extends flash.display.MovieClip.How do I go about swapping depths so that the largest one is in the foreground, I am new to AS3 and dont seem to be able to find a way of getting the depth of the movieclip I am currently inside (this) and if I try to access the stage to call swapChildren I get the following runtime error:

i am slightly confused about the parent and child relationship. lets assume we have several different instances, what would be difference of adding them all as children of the stage and creating a parent-child hierarchy between them(other than the access path).

I have 4 tab movieClips (Suppose 1_mc,2_mc, 3_mc, 4_mc).Not 1_mc is on top and covering some part of 2_mc, same as 2_mc is covering some part of 3_mc, and 3_mc is covering some part of 4_mc.Now whenever i clicked any tab Movieclip. it should come on top of all MovieClips.
in AS2 there was a method swapDepths(This.getNextHighestDepth()) and by that we can swap current movieclip by all other MovieClips.So is there any code in AS3 also, which can swap child at once with all the Movieclips? I checked from setChildIndex and swapChildren too but its taking more length of code and complexity too, to understand which movieclips has to be swaped now?

I use swapChildren(mc_1,mc_2) to switch depth between 2 movieclips from the root level. Everything work just fine....
but when I create a container_mc and place the two movieclips into it then the 1120: nullobject reference error occurs?? container_mc.swapChildren(mc_1,mc_2);

I have got a heirarchy of objects which goes like this -> stage.control_mc.gaincontrol_mc.knob_mc
i am trying to register an event listener for stage from within knob_mc using stage.addEventListener("mouseUp",this.mup2); and i have defined the function mup2 within the knob_mc class - but when i run the movie and dynamically add the knob_mc to the stage i get this error
TypeError: Error #1009: Cannot access a property or method of a null object reference.
i dont know why stage is a null object. when i trace stage from within knob_mc i get null....

I have a feeling I might be going about this all wrong. I have 3 objects (mask_cat, mask_dog, mask_sea_monster)on the stage and I want the user to be able to move them independently with the ol' click and drag. This is what I have:

I've ran into a very nasty little problem that has been buggin me for few days.
Basically I have a main (parent) swf which loads the content of the sub pages into a MovieClip called mc_container.
Inside every child SWF I have a code to repostion and resize its contents as I need with stage.addEventListener (Event.RESIZE, relocateandresize);
But the problem is, once this SWF is embedded into the main (parent) swf, this code stops working.

I have a Sprite called pageContent. Inside pageContent are 12 more Sprites with unique names, a couple of Buttons, and some TextFields. Inside each of the 12 Sprites I have either one or two TextFields and one TextInput. My question is, since they are children inside a child of pageContent, how can I access them? Here is how I am trying to do it:
[Code]...
In my mind, this should totally work. But surprise, surprise, it doesn't. I have debugged it and it works fine for the first two lines, but when it tries to get numChildren of a Child of pageContent (line 3), I get this error: PHP Code: 1119: Access of possibly undefined property numChildren through a reference with static type flash.display:DisplayObject.

in AS2 i can access it directly by changing itemButtonExp[a].text, but how do i do it in AS3?

I have 3 objects (mask_cat, mask_dog, mask_sea_monster)on the stage and I want the user to be able to move them independently with the ol' click and drag.[code]So far only the, sea_ monster moves. The odd thing is the sea_monster moves when I click on the dog or the cat also, but not if I click anywhere else.

I have 170 images that I need to place on the same place on the left side of the stage and and have them move across the stage one at a time, increase in size and then fade out after 10 sec. The sequence then continues for all 169 images. My initial thoughts are to animate the first image inside a movie clip, duplicate it and swap the image. When I tried this it worked fine until the image had shape tweened to the larger size (at this point the image displays for 10 sec and fades out). At the key frame at this point the image changed back to the original one. What do I need to do to make the new image visible throughout the whole movie clip when I swap the image like this? Is there a better way to produce this type of animation? I am using Flash Professional 8 and quite new to the world of Flash and Action Script.

I have a movieclip called "myClip" and I add a random child to myClip which is either "myChild1", "myChild2", or "myChild3" and inside of all of these is a child called "myLittleChild".
How would I call on the child "myLittleChild"?

Building a menu with drop downs. Each menu item is a child of a movie clip and has an "open" state and a "closed" state. When the user clicks on a menu item it "opens" and drop down menu slides out. If they click it again it "closes" and the drop down menu slides away. What I am trying to do is make any "open" menu items "close" when any of the other menu items are clicked. Here is a generalization of my code at the moment:

trying to remove instances of child/children. I have a function (btFnc) that creates a child (bT) and then the function is called several times to add instances to the stage - btFnc(264,3.6); btFnc(304,4.6); btFnc(344,5.6); btFnc(384,6.6); btFnc(424,7.6);Yet i cannot for the life of me remove all of the children, only 1.
Code:
public class screen18 extends MovieClip {
private var scrnXMLLoader:XMLLoader;//XML Loading class
private var screenTxt:Array;
[code]....
This then repeats for screens 2, 3 & 4.

I am working on an application that has buttons (movieClips) to set the color of user input (graphics, type, etc...). When clicked, the selected button displays a movie clip of a palette of 35 colors.I open the palette with the following function (is that the same as a method?):function openPalette(event:MouseEvent):void event.target.addChild(colorPalette);}I can then click on the colors in the palette to select the color I want.However, since the palette is a child of the button, clicking on a color within the palette triggers the same function as clicking on the parent button again. I get the following error:ArgumentError: Error #2150: An object cannot be added as a child to one of it's children (or children's children, etc.). at flash.display::DisplayObjectContainer/addChild() at design_AS3_ii_fla::MainTimeline/openPalette()

I am trying to create a gallery where each thumb is housed inside of it's own movie clip that will have more data, but it keeps failing because it won't let me refer to the newly created instance of the movie clip. Below is what I am trying to do.

It dies every time on that last line. How do I refer to that vidThumbn instance so I can add the imageLoader? I don't know what I'm missing. It feels like it should work.

I want 3 movieclips to change positions (swap places) on the stage randomly when I push a button and make sure they are always in different positions, so they don't randomise the same way.
cat, dog, fish
position_a,position_b,position_c
position_b,position_c,position_a
position_c,position_a,position_b
then loop and randomize the position they popup in again. So I can just keep on clicking the screen and they always change.
xxxa
xxbx
cxxx
I will have the 3 movie clips on the stage with instance names.
position_a
position_b
position_c

I'm trying to make a dynamic image gallery from and xml. From my tutorials, right now i've got it so it will constantly add the next thumbnail below the other, which is fine, but I'm trying to figure out how to make it that once it reaches a certain y coordinate, it will move the x coordinate over and stack them again. So that rather one long list of thumbs, it will be a side by side stack. For some reason, I can't get it in my head how something like this would work. My goal is to have a side by side stack that I will end up putting in a movie clip that will be masked to show only 2 stacks at a time. Then when clicking a button will slide it over. I was planning to use the "movieclip.length" to calculate how far over to move it, but i haven't gotten that far yet. This is what I got:

inside a MouseEvent.CLICK function, I usually used e.target to address the movieClip that I clicked, but that only work with a movieClip that doesn't have any children (such as text and other symbols) inside. When it has children inside, the e.target return the child inside the Mc but not the Mc itself. The e.currentTarget didn't work, either; it returned [object MovieClip] but not the instance name of the Mc.

What's the best way to scale a container mc but not scale the children inside it? Basically I have a box mc with a background colour, with a logo added using addChild, if the user changes the browser size the box scales to the height of the window but it's also scaling the logo, I just want to change the height of the container box really.
