ActionScript 3.0 :: Way To Iterate Through All Parents In A Display Object
Dec 10, 2010
I would like to know is there a way to iterate through all parents in a display object. I need to do this because i am loading swfs to application and swfs have different number of nested movieClips and i would like to be able to access loader properties like width and height dynamically from within any depth. How can i do that?

If I create a rectangle with 100px width and 100px height and then rotate it, the size of the element's "box" will have increased.With 45 rotation, the size becomes about 143x143 (from 100x100).Doing sometimes like cos(angleRad) * currentWidth seems to work for 45 rotation, but for other bigger angles it doesn't.At the moment I am doing this:
var currentRotation = object.rotation; object.rotation = 0; var normalizedWidth = object.width;
Can you make one Bitmap Object (I'm using an external jpg) or something similar, and then display it many times simultaneously without creating a separate object each time?
Also, would they be easily removed or hidden?
I've got a little checkmark jpg graphic loaded here, but I'm not sure how to go about using it in many places at once.. I can only display it in the one place at any one time...
I'm thinking there might be a way to load the picture once, then use its bitmapData elsewhere in new display objects somehow, without needing to reload the image over and over?
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.
How can i cast a object to another type? in AS3 i tried putting (objectType) infront of the variable but it doesnt work, below i have added objects of fishes into the child, and i am getting the fishes back out when mouse down is triggered, and then calling the fishes what to do. however i cant call the method of the custom class fish because it is a displayobject.[code]...
I have an created an associative array of MovieClips, but when I try to iterate through them, the for loop never gets entered (nothing gets outputted). It's like as-if the Array is empty.
var navItems:Array = new Array(); navItems["home"] = item_home; navItems["featuredfilms"] = item_featuredfilms;
Say, for example, I have a car on a flat plane. It can move either left, up, right or down. I also have 10 obstacles on the stage. Each time the car hits one of them it should automatically turn to avoid it. I could loop through each obstacle and check if it is colliding with the car but a better approach would be to make an obstacle class that checks if the car is going to collide with that obstacle and if it does, make it change direction. My problem though is what about if I had 5 cars? Would the obstacle class have to loop through each of the cars to check if any are colliding with it? My main concern with this is how much the performance of the program would be affected. I imagine with only 5 cars the difference would be insignificant, but what if I had 1000 cars and 1000 obstacles? Going back to the first example, it is easy to see how you can use a class as opposed to using a loop but with the second example, I just don't know.
Is it possible to iterate through a MovieClip's child MovieClips?
Lets say I have a MovieClip "a_mc" which itself is made up of n number of child movieclips. Is there a way to iterate through all the children without creating an instance for each one?
I'm accessing the classes from an externally loaded SWF so that I can "skin" SWF applications at runtime. Everything works fine but I'd like to make it as dynamic as possible and allow developers to access all the class definitions in a loaded SWF without having the FLA file or a list of their names.
I've got a loop which creates a movie clip for each day of the month and lines them up. so, depending on how many days are in the current month, the counter var for the loop is 28, 30, or 31.
Code: for(var j:Number=1; j <= lastDay; j++){ // Create the Empty Movie Clip _root.createEmptyMovieClip("dateClip"+j,300+j); var dateClip:MovieClip = _root["dateClip"+j];
Within this very same loop I am also using the same counter var (j) to iterate thru an array that is created from parsing my xml file. Now, I don't have 28, 30, or 31 dates in my xml file -- just about 4 or 5. so if i trace out this array I'll get values for the first 4 or 5 positions but then a series of 'undefineds' for the rest. that's normal, right?
Code: trace(ArrDate[j].attributes.day); The problem comes when I try to target the movie clip instances based on the "dateClip" and the "ArrDate". Here it comes up totally undefined in all circumstances.
Code: trace(dateClip["thisDate"+(ArrDate[j].attributes.day)]); I can trace out dateClip and I can trace out the ArrDate (even though it returns only 4 values and the rest undefined).
Question regarding math: I am trying to interate through an xml set (the xml will constantly change) and display 6 items at a time. If the total from xml is not divisible by 6 and lets say 4 left from the array, only show 4 and set the other attached mcs to false. I am adding them via attachMovie and basically do not know how to set up the math on it, can anyone shed some light?
I'm trying to optimize a site I'm building with Django/Flash and am having a problem using Django's iterate over chunks() feature. I'm sending an image from Flash to Django using request.POST data rather than through a form (using request.FILES). The problem I foresee is that if there is large user volume, I could potentially kill memory. But it seems that Django only allows iterating over chunks with request.FILES. Is there a way to:
1) wrap my request.POST data into a request.FILES (thus spoofing Django)
ok, my Digital arts class is making a flash project, and im like the only one actually making a game, so im pretty much alone. i got a lot of help from the people on the AS3 forum, but im pretty sure that my question is too easy to put there. so, i have an array, and it basicly puts a spike on the screen at a random Y, and moves it across the screen, but, when i hit a spike, and ti goes to the you lose screen, the loop keeps adding children, and putting them on the screen, is it possible to just say stop adding children, and go to the next frame? i have a break, but when i stop colliding with the spike in the next frame, the spikes start coming again. also, can i totally reset the movie? cause when i just go to frame 1, the array plays itself ontop of itself and it gets twice as hard
I basically have a large bar of items that fills up dynamically, they are all added to a dispCont movieclip as a container. When you click on one it gets pulled to the front, scales up and I want all the unselected Items to blur or become semi transparent. So i figured i could just tween the dispCont object, however this affects whatever is brought to the front, so i want to switch that into a new MovieClip called centerCont. Here is the code, ive been trying different things, I could just use a little input.[code]when I click on it because i am trying to set event.target.parent = centerCont;otherwise, uncommented and that removed i get Code:1118: Implicit coercion of a value with static type Object to a possibly unrelated type flash.display:DisplayObject.
