ActionScript 3 :: How To Update Array Automatically When MovieClip Null
Mar 30, 2012
I am trying out the following code, so that whenever I make a movieclip null, the array containing it's reference too becomes null. I understand the following code cannot do this, but I want somehow, the array can provide information, if the movieclip has got null.
import flash.display.MovieClip;
import flash.events.Event;
var a_arr:Array = new Array(a_Mc,b_Mc);
trace(a_arr);
a_Mc= null ;
trace(a_arr);
Output is:
[object MovieClip],[object MovieClip]
But I want something like null, [object MovieClip ]
I've been working on a project the last few days in AS2 and decided I'd try and re-write it in AS3 as I'm yet to venture in to the AS3 world. I've done most of the conversion, but I'm stuck on what should be an easy problem. I'm loading images from an xml. The images get put into movieclips.
I have a function that resizes the images when the stage is resized. This then runs another function to update an array of the image widths. The problem I have is trying to update the new widths into an Array. I just can't seen to reference my MC's to get the widths!
I've got a movieclip, which has got a dynamic text element.The movieclip uses a package for its codeThe package if obviously derived from the MovieClip classI've got a timer, that updates the dynamic text field every second.When debugging the code, I see that the timer works well. Its updates the value of the dynamic text field.
why i keep getting Parameter child must be non-null. And my code won't display 5 enemyBlock objects onto the stage but only just one.
returns: TypeError: Error #2007: Parameter child must be non-null. at flash.display::DisplayObjectContainer/addChild() at flash.display::Stage/addChild()
I have a project with an XML Connector that goes out and gets data from an xml file and displays it in a label in my flash. It does this when the swf file loads using ActionScript in frame 1. The ActionScript is simply: this.labels_xc.trigger(); It loads the data from the XML file no problem. But the data in the XML file changes every so often. How do I get the swf file to go out and get the new data on a regular interval (say every 2 minutes or so)? I've looked at scripts with timers and I can't figure it out. Here is the url to the page I'm testing it on:[URL]
I have datagrid binded with data acquired from web service which, as you may suspectretrieves data from some db. Datagrid has some editable columns and I want to update db through appropriate web service call without adding button "Update" as a last column in datagrid.
If i have flash reading from an XML file feeding the background color of the .swf. and that XML were to change... is there a way to have flash constantly ping the xml file and detect changes?
I have been having a hard time trying to stream from YouTube! It seems they have been changing things a lot. What I need to do is link a player on a flash (AS 2.0) site to a YouTube channel, so it will update automatically from the feed.
Im working with a flex application that pulls data from a java class file using message handler event. The received message string is added to ArrayCollection. The string consists of codeID and other values related to codeID. Had displayed the detail in a datagrid. The codeID is randomly generated and is pushed to flex for every second. Now, the problem is, I needa update the datagrid cell values, for instance, if i have pushed codeID's of (0001,0007,0005,0003) to the front end, that displays the corresponding values of each codeID in the datagrid, second instance of (0001) should update records in the existing row of (0001). I tried to check the existence of codeID in ArrayCollection using search algorithm, but dont know how to proceed further.
Lately I've found myself constantly writing removeEventListeners everywhere, which makes code quite messy. I know it's a best practice and such, but in general it has no sense. Garbage collector should handle such a simple task by itself, shouldn't it? Is it that hard to remove all listeners automatically when object is set to null?
So I just want to be sure if that's the case. Does setting an object to null, automatically remove all attached event listeners? In my case scenario is like this - I create an object and attach bunch of event listeners to it, then after a while I need to re-initialize this object. Of course setting this object to null is much easier then unbinding every listener by hand. And on most part listeners are anonymous functions, which means that it's not possible without code refactoring. When I simply re-initialize a variable with new I do not get duplicate listeners and such, but I'm not sure that it's previous value, along with all the listeners gets garbage-collected. Is it?
I am trying to use the following code to convert an object read in from a ByteArray to an Array and store it:
var data:Object = ba.readObject(); var invObjects:Array = data as Array;
In debugging, I find that 'data' is indeed populated with the correct data and takes up memory and is in an Array friendly format. However, invObjects is NULL. How does merely saying 'data as Array' make the holding variable suddenly null?
Have recently started de-activating "automatically declare stage instances" in order to get code-completion for stage assets in FlashDevelop and also because I find it's better to have visible declarations of all class properties. Problem is that I'm getting some weird issues with TextFields being null for no apparent reason. For example, I have a MovieClip with a linkage class - this works fine. Any Sprites within it work fine and can be accessed in the Class itself. However, all TextFields are null despite being declared in the Class and instance named in the IDE.
filterFunction is a method to apply a filter on the content of a collection.But the filter is not apply into the orginal Array (the one which use in the ArrayCollection) So, after apply a filterFunction, the original Array lenght doesn't change, neither the content because the Array is not update; Only the Arraycollection does changes after filterFunction method.is there anyway to synchronise the content of an arraycollection with an array ?
I'm trying to write some code for a simple product scroller.I have an array of product items and when the user clicks the next button I want to remove the item at the last index of the array add add it to the start index and then update the stage with the results.
I have an inputbox and a submit button and prev and next button in my screen. Whenever users enter a text in the input box and clicks on the button, the text value is stored in an array. Then users click on the next button and again enters new value in the inputbox and click the submit button. The new value is added in the array.
Now suppose if users want to make correction to the values that they have entered for previously entered values, they can click on the previous button and make correction and click on the submit button.
For this I think, we have to remove an array value and add a new value to it. I am confused on how to remove and add a new value to that particular place.
Do I have to use Array.splice method. I think using the splice method I can remove an array item but how can I add the new value to that particular place. For example if users want to make correction to the second item, we should replace myArray[1].
I think I must be missing a step here; I have different data being pulled from an array created from xml depending on a variable (_currentTrackNum).. and the data changes if I set a different initial value for it; but if I change the variable once the program is initialized, none of the data changes even though I rerun the call with the changed variable.[code]
i'm running a simple nested for loop (code below) that when you go over a tile makes it change its color, so far so good but i also want to make it so that when you go over a tile you can then continue only on the tiles connected to it
Code: for (var colum = 0; colum < field_h; colum++) { for (var row = 0; row < field_w; row++)[code].....
i think i should be able to do it using arrays but i can't seem to understand how after the tiles are placed and the array updated accordingly to update the tiles with the new array value (enter frame event ? )
I got a small animation, which starts by the "StartIt" function and keeps going with the "PlayIt" function by triggered by MyTimer. In "StartIt", I let AS save the positions and other stuff of my MC's in order to replace them to their original positions by "StopIt". But strangely, those Arrays keep changing to the MC's ACTUAL position according to the Timer triggered "PlayIt". "Universe" is a custom class, that only calculates new positions.
Code here: var PosxSave:Array = new Array(); var PosySave:Array = new Array(); var VabsSave:Array = new Array(); var VangSave:Array = new Array(); [Code] .....
I have a class called FC. I want to automatically put all instances of it on an array. I think the best way to do this would be to use a loop. I would usually use a For Loop to automatically add code to object by having flashplayer run through the display list. However, instances of my class are not added to the display list. How can I automatically apply code to them?
I was wondering if anyone could help me achieve an outcome for a soccer game penalty shoot out. I have to put the two defenders and the goalie in an Array. they need to move at a set speed automatically to the left and right side of the goal.
I am trying to create a text box which I can dynamically update from an XML file and move around in 3D at the same time. Is it possible?
I can create a dynamic text field and update if from an XML file and.I can create a dynamic text field, convert it into a Movie clip allowing me to move it round the screen but I can't do both without losing the text (I have also tried embedding the font).
Is it fundamentally possible in CS4 or CS3 to dynamically update a text field once it has been converted to a MovieClip/Symbol?
This picture gallery adds children. It does what it needs to, but throws a #2007 error. //Picture Gallery var um0:MovieClip = new z0; var um1:MovieClip = new z1; var um2:MovieClip = new z2; var um3:MovieClip = new z3; [Code] .....
ERROR TypeError: Error #2007: Parameter child must be non-null
ActionScript Code: public function draw():Card{ return deck.pop(); //deck = array of Card } Does not work. Firstly it runs an error which says "cannot convert [] to Card"... Shouldn't it pop() return just ONE element?
Then I correct like this ActionScript Code: public function draw():Card{ return deck.pop() as Card; //deck = array of Card }
And now I get no errors but the function returns null.... why? If I try this: ActionScript Code: public function draw():void{ trace(deck.pop()); //deck = array of Card } It prints [Object Card] which is how it should be ....
I am deploying Updates via SCUP and SCCM to hundreds of Computers. Fortunately Adobe provides an SCCM Update Catalog for both Adobe Flash ActiveX and Adobe Flash Plugin. But now my Problem: After publishing the Update via SCCM, the client is not supposed to be interfered with the Update Progress (which is working) I figured the Updater works like this: First SCCM checks if a Update needs to be deployed, if this is the case, The Flash Updater begins. First the old Flash Version is beeing uninstalled. But now: if the Client has a Browser Window (IE, or Firefox) open, the Updater is not able to install the new Flash Version and quits with an Error. This leaves the Client PC without any Flash (because its being uninstalled before) How can I prevent Flash being uninstalled due to the Update progress not working while a Browser window is open?
