ActionScript 3.0 :: Creating A Conditional To See If Child Exists
Mar 9, 2010
I m making a basic menu effect. Normally I would animate all this in flash on the timeline but im trying to learn as much as i can about coding. I was actually impressed that i was able to create just this simple animation, but i want to write a conditional that lets me see if a child exists on the stage, if so remove it, if not run a function. Heres where I am so far.[code]as you can see the hardware text drops down and comes in from the top but stays on screen when you mouse out.basically what i want to do in my hardwareOut function is to run a conditional to see if topText exists, if so remove it and if not then gotoAndPlay().
I am trying to add a Child to the stage depending on what xml string is loaded based on a button click. I created a function for buttonFeedback but it breaks my code
My page has 2 tab menus. When the page first loads, it defaults to the first tab, but when the second tab is hit, an image is loaded to the stage. I want to remove the image from the stage once the first tab is hit again.I keep getting the error "Access of undefined property Image1" but the whole point is to check if this child exists with the if statement.
//Tab 1 if (Image1 != undefined) { stage.removeChild(Image1);
I have an event driven flash program. I need to be able to call removeChild() if and only if an object is a child. getChildByName() and most other functions don't seem to allow for this and if you call removeChild() on an object that isn't a child it will throw an error. I suppose an option may be to catch the thrown error and just ignore it, but that seems like a bad solution.
I have been through many threads and none have helped. I am trying to remove a child if it exists. I am clicking on the button and sometimes there is no other child loaded. I want some code that looks to see if a child is loaded and then if so unloads. There are going to be at lease 5 possible .swf files loaded. [code]
With this code, I need to determine if the xml child is null and form a conditional statement upon that info.I have it very close but something is just "un-tweeked" enough that it wont work correctly.AS3 and XML provided below...
Code: var url = txtBox_mc.getTix.url; var request:URLRequest = new URLRequest(url); txtBox_mc.getTix.addEventListener(MouseEvent.CLICK, GetUrTix);[code].....
The problem now only the " if (url == null) { " is read, thus returning those results. I believe the issue is within the definition of url " var url = txtBox_mc.getTix.url; "...
I'd like to remove a child of the display list if it exists before adding another to the stage. This gives me Error the first time I call it because 'myMC' doesn't exist.
HTML Code: function callMc(){ if(myMc) removeChild(myMc);
i am slightly confused about the parent and child relationship. lets assume we have several different instances, what would be difference of adding them all as children of the stage and creating a parent-child hierarchy between them(other than the access path).
I want to ask if someone can give me an example of creating child through xml. I mean creating custom components through xml (for every xml tag you create your own custom component and then add it as a child to the stage). I hope is it clear enough... :)
I am creating a pile of stackable movieclips. The dragging function is not a prob but I have a problem with the parent/child relationship in the "bringtotop" function.
Code: package { import flash.display.MovieClip; import flash.display.Graphics; import flash.events.Event; import flash.events.MouseEvent; public class Colorbox extends MovieClip { [Code] .....
The error generated is : RangeError: Error #2006: The supplied index is out of bounds. at flash.display:isplayObjectContainer/setChildIndex() at Colorbox/bringtotop()
I have a picture on the stage that has multiple items that have hotspots/links over them that should open a child swf on top of the background and show details about the items. then have a button in the child swf itself that removes the child from over the background so the user can click on another item etc.I found this code in someone's post and I am trying to modify it so that works for multiple swf files...it currently works for a single swf.I wan to pass the name of the button in front of the .swf in the URLRequest to have the same name as the instance name of the referring button. But I can't figure it out. Here is the code I am using on the stage
So I'm not that familiar with using conditional statements yet, and I'm trying to get my head around it. I know what I need it to do, I'm just not sure of the correct syntax.I basically want a statement that says:
if( movieClip1 == frame 10) { then play movieClip2
I have FLV files that continue playing when I leave the frame that they are on. I can stop the playing FLV by putting this code on the following frame:
if (demo.playing) { demo.stop();}
Where .demo is the name of the instance of the .flv component.
Here is the problem - I have many frames with many flvs, and when I tell flash to stop multiple FLVs, for instance:
if (demo.playing) { demo.stop();} if (demo2.playing) { demo2.stop();}
I get this error: TypeError: Error #1009: Cannot access a property or method of a null object reference
As far as I know, flash is telling me that since the instance of "demo2" has not started playing yet (ex. the user only went to the page with the "demo" flv, but not the "demo2" flv yet) that flash has no idea what demo2 is yet. I thought using a conditional statement would remedy this, but I suppose the .swf can't stop playing something it does not yet know exists.
Is there any way I can introduce all of the flv's at the beginning of the file, yet not have them play and not have flash "forget" about them so that I can stop them using the code above? Or is there a way to have the conditional statement not error in the event that the referenced instance has not yet been "introduced"?
I really wish they would have added an "exit frame" command in AS 3.0...
I'm trying to make a gallery loaded from external files, and I try to not use ready packages or swfs, so I wrote a code. I have many images in a folder and a xmlListfile of this images, and I accomplished to load them one by one, but when the list reach to end in both ways (start or end), Button function for the next images continue to work, I treid to solve to problem with a conditional in function but it didn't help.
The code is:
ActionScript Code: var i:uint = 0 var imageLoader:Loader; var xml:XML;
It's a little more complex than that, actually. Inside a function, which is called by a Timer Event, I have many conditional statements based on CurrentCount of my Timer. Nested within these conditionals are more conditionals. <<<I know it's amateur programming, and I'm sure there are much more elegant ways, but I'm just learning (via attempting a difficult challenge).>>> One way I'm trying to control all these conditionals is via a random number, from 1 to 3. My problem is that after generating the number within one "if (currentCount == )" statement, the variable is no longer available to be used by the next "if (currentCount ==)" statement. Is this some terrible side effect of using the Timer class??
Code: var timerMain:Timer = new Timer(900, 25) timerMain.addEventListener(TimerEvent.TIMER, takeTurn); timerMain.start(); function takeTurn(e:TimerEvent):int { if (timerMain.currentCount == 4) { [Code] .....
I have a gallery loading jpegs from an xml file into a mc called mainPicArea, on frame 5. I have other content on frames 1,2,3,4,6,7.I want to run an if statement to check whether mainPicAreaexists and if it does, then run a removeChild(mainPicArea), and if not do nothing.
code: if (MovieClip.mainPicArea){ trace("exists"); //removeChild(mainPicArea);
[code]....
this is my code. When I test, it comes back with the trace "doesent exist", even though it does exist.
Is there a way to see if a class exists? something like:
if( MyClass exist in the Library or has been imported in to the class ){ var myClass = new MyClass() addChild(myClass); }else{ trace("MyClass doesn't exist") }
I'm not trying to see if it exists on the stage just want to know if I have access to it.
Im gonna make an image gallery that loads thumbnails 1.jpg, 2.jpg 3.jpg..etc... into thumbnail mc's it creates, and when it gets to a number of a file that doesnt exist i want it to stop making thumbnail mc's. What AS could i use. As of right now it trys to load the jpg that doesnt exist and the preloader keeps going forever.
i have problem with swfLoader in flex, when i close following code in click method i can easly add many swf to main application
<mx:VBox id="content" width="100%" height="100%" ></mx:VBox> public function doIT():void {[code]....
when i close adding those swfs in loop i have the same error, it looks like child apps couldn't access certain objects that were instantiated by another child app, so what can i do?
I have a movieClip with one frame on the timeline containing one child whose instance name is "myContent"I am using this function to swap "myContent" with any number of possible class instances.
I've used this site as a resource leading up to this, not particularly sure if I worded this correctly I have a class "Block" which is just a square (will be something else later on in the process) I want each block to have controls to add an additional block in either direction so I have another class BlockButtons which has my buttons for each direction.
And another class GlobalVar where I keep all my variables for funsies
In the code below how can I use the movieclip in the conditional statement? This is simplified, there is lots more going on but the basic issue is shown. I want to say if currently dragged mc is dot1_mc do the copyDragTo35 function
PHP Code: var item:MovieClip; //add event listeners to all dots kite_mc.dot1_mc.addEventListener(MouseEvent.MOUSE_DOWN, onItemDragStart); kite_mc.dot2_mc.addEventListener(MouseEvent.MOUSE_DOWN, onItemDragStart); function onItemDragStart( e:MouseEvent ):void {
