I have an XMLListCollection object that contains items with an ID property. I want to find one particular item by id and then get it's index in the collection. This is done to be able to tell the comboBox (whose dataProvider is the XMLListCollection) the index of the item to display.

So, for sending to individual streams we have to reference the connected netStream we want to send to in some way like this:
sendStream.peerStreams[0].send("MyFunction",param1,param2);
and I have to determine which peer I'm sending to by their ID such as "peerID1234"
I know that you can check the peerID of the stream by doing:
sendStream.peerStreams[0]["farID"]
how can I make my send stream function know to use the array index where the peerID is?
so basically it could be like:
sendStream.peerStreams[where peerStreams[]["farID"] == peerID].send("MyFunction",param1,param2);
I use flex4 list[code]...
as far as i know , i can only know the the index that i already select by function
list.selectedIndex
did flex4 proivde some other function that i can use?
I have a simple list in Flex that is populated every N seconds by a dataprovider. My goal is to avoid scrolling the list after the dataprovider has been changed.
So, before I populate the list, I save the selectedIndex, and once the dataProvider is filled, I call:
list.selectedIndex = index;
list.scrollToIndex(index);
Trouble is that this moves the selected item of the list to the top. The solution would be to get the index of the first element displayed in the list: but I have no idea on how to get that.
How can I delete the element with a certain index in a Flex XMLList?
View 1 RepliesI'm trying to create a virtual keyboard.
I have a class VirtualKeyboard which contains an array called keyboard of 26 movieclips, each one representing a letter.
In the main class, I create an object of the class VirtualKeyboard and added an eventlistener on it when a letter is clicked.[code]...
But the index always returns the value 4294967295.
How can I know which letter was clicked, I mean the index in the keyboard array corresponding to that letter?
The same code is working correctly if I put it in the VirtualKeyboard class, but not from the main class.
I search the stage for the level I created and put the floor pieces into an array. I'm trying to test the properties I created for each piece by tracing to output when the hero sprite is within the floor pieces sides. This works fine when I specify the array index to do this for, but does not work when I try to loop through every element of the array. I see no reason why this code should not work.

Say, I have an array of movie clips (dummies). Each dummy has an event listener and reacts to clicks. And when a dummy is clicked, I want to know the index of the clicked dummy.
I've only come up with this solution: run through the whole array of dummies and find out which dummy is the target, then exit the 'for' cycle and assign some global variable the value of counter variable, but this way the application I am building will demontsrate poor performance.
Supposing that i've a lot of MC placed on stage, every MC is stored into an array. Clicking on one of it, can i retrive the position in which it's stored into the array?

Here is the problem I have: after I change the index of one movieclip using this code
oldIndex=getChildIndex(DisplayObject(e.target));
setChildIndex(DisplayObject(e.target), numChildren - 1);
when I give the object its old index
setChildIndex(DisplayObject(e.target), oldIndex);
and go to another frame of the movie, this element I have changed the index of stays on top of all elements on the new frame. My question is am I doing something wrong and if not, what can I do so that this element stays only in the frame it is placed.

View 2 Repliesi'm breaking my head over something, and will be very grateful to any creative ideas:
I created kind of drag and drop game: i have cards that should be placed on squares.
in case the card touches any square, the square changes it's color. the problem occurs when the card touches 2 squares at their middle: they both change their color.
in fact, I need that only one of the square will change it's color, and it should be the square that the card touches it with "the most of him". i thought of using the hitpoint but i know it won't work, because in case the card touches both square in the middle it won't work..
Like I have a parent with 5 children which are the same type of object, like the same class. Is there a function or property that tells me what index this particular child is in its parent? Like this child is the 3rd child in its parent.
View 2 RepliesI'm building a plugin and I'm using actionscript to save the selection of an object in an illustrator document and then reference it later.
var arrObj:Array=new Array();
arrObj.push(app.activeDocument.selection[0]);
If I select now the same object in the document and check if its in the array it returns a -1 for the index value.
var id:int=arrObj.indexOf(app.activeDocument.selection[0]);
trace (id); //-1
Why is the selection not considered the same object as in that of the array?

reading the index from an array object?
if I have done something like this:

I'm writing a multi-layered drawing app, and I want to be able to move the layers up and down. It's easy enough to change the objects in the display list and move the buttons, but in order for it to work continuously I need to be able to change the index of the button objects in the array so they are targeted properly by the function. Is there a way to do this in AS3?

Is it possible to control an object/element on a instance? If so, how is it done through actionscript? There is an instance "instance140" off of the root, that has an element named img4 that i need to reference... does anyone know how I would go about that? using root.instance.object form returns undefined.

updateObject is the loop for all my objects. I have one centralized loop and in that loop it calls on an array of objects that have been placed on the stage. all of them containing the method updateObject. to update the status of the object. addGameChild() is a encapsulated addChild() , that not only adds the object to the stage, but places it in a array so it's updateObject() method can be called on. it is also used to make it easier for garbage collection.
How do I find an object's index in an array
I have an array of objects similar to[code]...
After chatting with my coworkers, they have suggested I enumerate this into a large array of indexed values with references to which index they are associated with, for instance [code]...
I was just wondering whether it would be possible to remove an object from an array without referencing its index, for example when the index is unknown, or when you want to splice it from within the class itself, like ina die function for an enemy in an array. I have a project due on Friday morning, GMT.
