AS3 How can I solve the bug of setChildIndex - actionscript-3

I've gathered all game pages on different frames of movieclip called game. in that game movieclip there are 4 different frames. on third frame I have some drag & drop functionality. When I drag one item, I want it to be on the front, I mean all other objects on that frame must not block the view of current dragging object. I used this.setChildIndex(currentDraggingObject,this.numChildren-1); but the problem is whenever I drag objects, when I change the frame, those objects are shown on that frames as well.
In short description: When I set an object's Index in MovieClip(game) , that object is seen in each frame of MovieClip(game) , how can I fix this?
I've searched the result online but couldn't find a solution.
Thank you

Instead of this:
this.setChildIndex(currentDraggingObject,this.numChildren-1);
You can simply use this:
this.addChild(currentDraggingObject); //shorter and clearer
If you have some object on a frame and you actually add it again, it indeed stays there in the other frames (I found this out too). The best/fastest solution would be to simple remove them before you are going to change the frame with this.removeChild(object)

as3 how can i prevent that a new instance is created by entering a frame?

i am working with several nested movieclip objects in a project. but i get into trouble with the buttons i created and implemented in the nested movieclips:
to describe it in a simple way:
I have a main movieclip with five frames, including two buttons with listeners to browse between the frames. Then inside of one Frame I have another movieclip with its own buttons. i instanciated it by hand not through code and gave it a specific name like "nestedMc".
Now I dont want to build the Listeners for those buttons inside the class of the nested movieclip class but in its parent class, which works fine until i then goto another frame in the main movieclips timeline and come back.
obviously every time flash enters a frame its contents get created anew (and therefore get new instance names). I could now try solve this through filling the frames via code.
But maybe there is another way to make sure the frame contains the same instance everytime i enter?
Timeline scripting is a dirty business, and really, a carry-over compatibility layer for Actionscript 2 projects. Whenever possible, I highly recommend not doing it, and simply keeping all of your code in your document class. As you're experiencing, timeline code causes headaches.
Consider instead just creating both states of your Stage (it sounds like that's what your two buttons are jumping between) and simply hiding them offstage or setting their alpha to zero and their mouseEnabled state to false. Furthermore, if the purpose of your frames is to play animation (a tween), consider instead switching to a much more powerful suite such as TweenLite. Moving an object over a hundred pixels (smoothly) can be as easy as:
TweenLite.to(redBall, 3, {x:100});
Now, if you're manually adding these items to the stage, as long as the object is a dynamic one, you can assign an instance name to it which will be saved between frame loads. Be aware the object name is not the same as the instanced name. For example:
var redBall:Ball = new Ball();
redBall.name = "bubbles";
The object's name is Ball, but it's represented as a variable called redBall. Its actual DisplayList name will likely be ambiguous (such as "Instance71"), and I can manually define it as "bubbles". 3 different names for the same object, all very different and necessary.
Even if you give the object a displayList name, you may not be able to reference it through code unless you enable Automatically declare stage instances, which basically creates on each object a pointer to the displayList object.
That said, you can always fetch the object by other means. Obviously, your buttons are always appearing, but you're trying to find a very specific object on the stage. At this point, we can use getChildByName() or getChildAt().
Hope that helps.

Merging MovieClips into a larger MovieClip

I have these 2 separate FLA (AS3) files and I want to merge them together. One FLA, let's name "Animation.fla", consists of a 1-frame animation with a class assigned to its main stage, let's label it "MainStage.cs." The other FLA file, label it, "Navigator.fla", consists of 3 frames where I have to navigate different frames to get to the animation on the Animation.fla.
I have tried nesting the two but I gain errors when trying to convert the whole Animation.fla to movieclip and put it on the frame of the Navigator.fla. It's seems it's not the correct way to do it.
Please fill me in with ideas on merging animations with Classes since I'm still new to this.

This is one way to do it. It could be that your code has errors. Please post your code.
In the meantime, check if:
-your MovieClips have instance names
-you are referencing your MovieClips correctly in your code.
You could you create a new movieclip on the stage of Animation.fla and select all of the frames in Navigator.fla, right click and "copy frames". Then go back to Animation.fla and paste them into your new movieclip. This will work if you don't have a main class in Animation.fla.

AS3 Play contents of a symbol

I've grouped a multiple layer 1 frame actionscript driven animation into a symbol. (simply put, imagine a 1 frame image being tweened by code over a few sec, in this symbol)
Now I'd like to play the contents of this symbol using an event listener.
But
stuff_mc.gotoAndPlay(1); and Test Movie doesn't play a thing (doesn't even show the contents of the symbol (the picture) which can actually be seen on stage).
If I go inside the stuff_mc and Test Scene, it works perfectly..
So how do I play stuff_mc from the stage?
Thanks in advance
It sounds to me like you are using multiple scenes. If that's the case then this is most likely where your problem is. Scenes are generally a bad idea in Flash – Adobe itself admits this.

How to click through a display object in Flash with AS3?

I am creating a photo editor app where, at some point, the photo you edit is supposed to be dropped between two layers of DisplayObjects (a background image and an image mask.)
There is a problem, though. When the image you are editing is dropped between the background and the image mask layers, it becomes unclickable, and therefore gets stuck there, with no chance of dragging it again. (The photo editor uses TransformManager library.)
I am looking for a way to allow you to select the image you are editing no matter if there is another DisplayObject on top of it. And that probably means finding some way to click through the image mask.
Is there a way to do that?
I tried setting mouseChildren = false on imageMask, but that didn't have the desired effect.
Many thanks.
I had similar problems and I managed to solve it by using both
displayobject.mouseChildren = false;
and
displayobject.mouseEnabled = false;
on the object that you want to click through.
How about this?
mask.mouseEnabled = false;
You can always attach a Mouse Click listener to the container, and then either use GetObjectsUnderPoint and check for your object or do a hit test and see if the mouse position is over your intended object.
The hit test would look something like this !this.YourPhoto.hitTestPoint(stage.mouseX, stage.mouseY, false)

If I understand your problem, this handy class should solve it:
http://www.mosessupposes.com/utilities/InteractivePNG.html
Take a look at what senocular does here, specifically in the handleUpdate method. Basically: getting a list of everything under the mousePoint to find your object.
I think I stumbled upon similar problem, although in as2.
In flash when you position movie clip over movie clip, and the movie clip on the top has any mouse events implemented, it captures all mouse events so they never reach occluded movie clip.
The solution is not to have any mouse events for the top movie clip and have the movie clip positioned at the bottom capture mouse event and redirect some of them to the top movie clip (you can check mouse position with hitTest to determine if they should be redirected).
i had a strange bug i used;
movieClip.mouseEnabled = false;
but wasn't working for some reason.. was driving me crazy!! as i have used it so many times before. tried lots of different things nothing worked then i deleted the MovieClip and the created a new one and worked.. so the MovieClip's contents must have been corrupt or something as it had a old dynamic Text Area box embedded within the MovieClip.
hope this helps someone out there..

How to make an object be ignored and letting mouse evnets pass through?

Hallo, I been having this problem for a while and I have no idea how to solve it.
I have a flash game (very much like a normal memory game) that has a lot of Movieclips in it that has MouseEvents attached to them. But, when I add a bitmap over the stage (used for covering lots of unwanted things and has to be there) that is the full size of the screen non of my events are fired anymore. The reason is that the overlay bitmap is stealing all of the events.
How can I stop this behavior? Is there a way of letting the events pass through the overlay object? Or for the overlay object to be ignored when it comes to events?
Thanks.
Assuming your overlay is stored in a variable m_overlay, then
m_overlay.mouseEnabled = false;
However you said it is used for "covering lots of unwanted things" so perhaps we need more information on what you are trying to achieve?
I've solved this in the past by creating "proxy" object to capture mouse clicks. The MCs under the bitmap aren't going to receive events.
