I'm working on a game that has many elements on stage, so I'm looking to optimize my loops. I know that Vector is faster than looping an array, but I'm also in some cases using:[code]My question is when I use getChildAt, is that accessing an Array or Vector or linked list or other? Should I instead store references to my objects in a Vector and loop through that instead?
View 2 RepliesI have a list containing display objects from throughout the application (insertion order). I want to process the list either top-down (parent, child) or bottom up (child, parent). The only requirement is that either a parent is processed before any child or vice versa a child before its parent. What is a good approach? This question is not about sorting a list. It's about retrieving the depth of a particular display object.
Example
Display list:
A (root)
B1
C1
C2
D1
B2
......
My list:
list = [E1, F4, A, B2, B1, C3, ..., N9, N8]
Bottom-up:
N9, N8, F4, E1, C3, B2, B1, A
Top-down:
A, B2, B1, C3, E1, F4, N9, N8
Does not matter if N9 before N8 or N8 before N9. Important is that any N is before M (first run) or any M before its children N* (second run).

View 1 RepliesDoes anyone have suggestions for a good method to manage the display list in an actionscript 3 project? I'm building an application at the moment and keeping track of all the modules which need to be displayed and reordering them has become unwieldy.I have loaded swfs and instantiated classes that also load in swfs, images and video.. Should I just reference everything to the stage? How should I keep track of the display tree? How can I always force one particular module to the top of the tree?
View 3 RepliesShort Answer: Yes, FullScreenEvent temporarily adds 1 child to the stage. Long Rant: Well how about that.. I'm not crazy.. I don't know if this is documented but - it's true. That little message that pops up saying 'you can press esc to exit full-screen' adds a single child to the stage temporarily and keeps it on the top level until it fades out. The sudden intrusion of indexes really messed me up.. so there's my answer, I guess. Now i just need to figure out how to get around this slight annoyance.
[Code]...
Now, bear in mind i'm not ruling out that my code is faulty because that's more than likely the case, but after pondering for ages and coming up empty handed, I keep getting a little superstitious that flash is playing tricks on me and that the 'little message' is not independent and is actually added to the display list..
Does anybody know if I'm just imagining things? or is the 'press esc' message a part of my swf on the display list?
I am using several instances of the same custom component on the same SWF. The component is essentially just a textfield with special sizing requirements. I also have another "wrapper" component that deals with the info from the textfield components. I was initially planning on using the stage index to associate the data with the textfield component it came from. This became more complicated than I anticipated. When I trace from the wrapper i can't get the index of the textfield components. So I got it in the component code and sent it with the info to the wrapper via a custom event. The problem there is that i can't tell which component is which because they are indexed identically. I can also see the component shim as well as the textfield.I'm just really confused about how programmatic components work on the display list.
My main Question. Is there a better way to associate the info with the proper component? I guess that's my only question. Please point me in the right direction.
EDIT2: I created a dummy place-holder component that just draws a rectangle then at runtime replaces it with programmatically generated textfield component.
It's my understanding that a display object cannot be in the display list more that once.So if I add something to the stage shouldn't a second addition of the same object replace the first? for instance:
[code]...
there should now only be one "myDisplayObject" on the stage.
If an asset (say an swf) is already loaded. Does it increase memory use to add and object to the display list?
View 4 RepliesIf anyone has a framebuffer implementation, could you please share some performance benchmarks? Or at least tell me how much difference are there in your point of view.

View 4 RepliesI have a list box in my flash file that I would like to display a string from an xml file that has been run though html entities in php. So for instance I need the string.
Code:
Hey "Leonardo£$£$()*%£% '"' [1999]
to display as
Code:
Hey "Leonardo;$;$()*%$% '"' [1999]
I can get this to happen in my dynamic text boxes by using .htmlText to display but I have no idea how I would do this in the list box?
I've got MovieClips on the stage, both manually added, and added with code. I used this code to trace them all:
for(var i:int=0 ; i<stage.numChildren; i++) {
var myObject = stage.getChildAt(i);
trace(i);
trace(myObject);
}
All it returns is 0 and [object MainTimeline]. Is there something wrong with Flash, or did I do my coding wrong? The objects I put on the stage should be on the Display List, right?
How do I removeChild only if it's in the Display List?One button on my stage will addChild(radioButton) and another removes it. If the remove button is clicked first, then it obviously tries to remove something that has not yet been added and an error is returned. I've tried using the DisplayObjectContainer class with the contains() method to no avail.
View 12 Repliesin my Main.as file, this works as expected:
var t:TextField = new TextField();
t.text = "hello in main";
addChild(t);
However, when I create an instance of a class, and I have that same code in the constructor of that class, the text doesn't show up. I am creating the text field variable at the class level, not the contstructor level, so I think the variable should still hang around.
Do I have to get an instance of the stage, or something?
The documentation for the List component at[URL].. states "A list can also display graphics, including other components," but nowhere can I find an example of HOW to make this happen. Can anyone please point me to a working example, I really need to be able to leverage this functionality, but I cannot for the life of me find anywhere it's being done.

Is there a way to make a display object always be at the top of the display list?For example, I know you can set the childIndex, i.e:setChildIndex(myDisplayObject, numChildren-1);But is there a way that an object has sensed that something else has been added to the display list and restack themselves accordingly?

Ok so my document class loads pictures and adds them every so interval once they're done loading. So when the next picture loads, it will be higher on the display list than the picture previous to it(on the left). So if a child(a tooltip) of the previous picture(on the left) appears over the picture to the right, the tooltip will always appear underneath that following picture, since the tooltip is a child of the previous picture.how do i get it to appear above everything? (addChildAt won't work) . i need a quick fix, is there a way to get my document class to add that tooltip ?

View 2 RepliesI'm making the game Breakout as an AS3 application using OOP. I am getting very confused though. I know that objects should be only responsible for themselves. But this is where I get stuck, they need to communicate as some level to add and remove screens, and I am getting majorly confused as to what is going too far, when it could maybe achieved in a simpler more OOP way. I've worked out the hierarchy of my classes, in terms of where they are being added (I think). I've added a screenshot of the hierarchy.
Have I got the order right based on OOP principles? Like, Introscreen will listen for play being pressed then call a method of the document class that will remove introscreen and then attach gamescreen. Is that right? Another thing that puzzples me. It seems to me if I made a level and put the paddle and the ball in that, then arranged all the bricks in that level, that I'd be duplicating work (based on the fact I need paddle and ball for level 2 also). So it would be best if I could have gamescreen with paddle and the ball and then add level1/2/3 to display list which would therefore set up the appropriate brick placement. But then, wouldn't that mean that I couldn't do hittests because my level 1/2 or 3 wouldn't be a sibling to the bat and the ball, them residing as a sibling in the level's parent class?
