I have a movieclip created with the following code:
var thumbContainer:MovieClip = new MovieClip();
thumbContainer.name = "thumbContainer";
stage.addChild (thumbContainer);
If the window gets larger/smaller I want everything back in place. So I have an stage Event Listener. Now I want to see if this mc exists to put back in place. I've tried different ways but keep getting an error that does not exist.1120: Access of undefined property thumbContainer.
if (this.getChildByName("thumbContainer") != null) {
trace("exists")
}
In AS2, I'd create a movieclip and give it an instance name. Then all I'd have to do for example is, check if _root["myinstance"+i] == undefined but in AS3, if i'm dynamically creating 10 movieclips, how do i check to see if it already exists?
What can I use to check if a movieclip has been added to the stage yet without flash throwing a bunch of errors at me? For example, I have a movieclip with the instance name(mcONE) on my stage. And I'm currently using this bit of code to check if it's on the stage
How can I check if the stage contains a movieclip on a specific x and y location on the stage?I'm building a colour-guessing game. The purpose is to walk a path through a generated field of hexagons, each assigned a random colour (yellow, red, blue or green), based on what soundfile you hear. So if you hear "yellow", you have to click a yellow tile etc.But because I want it to be a path, and the colours of the tiles are randomly generated, I have to check which colours border the currently active tile. I literally have no idea how to do this. I thought this might work but it doesnt:
if ((this.tile.y == (event.currentTarget.y - 64)) != null) { //add the colour of this tile to array }
I have a Dynamic text field embedded into a movie clip on the same frame different layer there is some action script. A series of If statements Which is basically to see if text field contains text so if it dosent contains text I can assign text to the text box
There is no text. Yet the if statement is false. Is this a logic error or is there a better method of achieving this PS i have tried orderMenu_mc.Item2_txt.text.length == 0 which also evaluates to false when there is no text in the field.
I want to check if the element in this structure exists for each child. The problem is that the children don't have the same name (product,prepack) and I don't want to change the order. Additionally I can't change the XML structure.
I am using flash cs5 and developing for iOS. I am using the application storage directory as well. But, in my code, a file in the storage directory is trying to be read before it is created, and therefore results in errorst?
if (XMLData.product[i].image[0].thumb) {thumbURL = XMLData.product[i].image[0].thumb;}Returns: TypeError: Error #1010: A term is undefined and has no properties.Same withif (XMLData.product[i].image[0].thumb!=undefined) {thumbURL = MLData.product[i].image[0].thumb;}
I want to add the possibility to take a webcam picture to my project, but only if the user's system has a webcam installed (obviously). In other words, those without a webcam should not notice the new function at all.
So basically, I need to check if a webcam exists on the user's computer.
I found a couple of ways to accomplish this, but none seem to work when I test them on a webcam-less system.
* One way to detect the presence of a webcam is to check if (Camera.names.length > 0).
However, on my 'blind' (webcam-less) computer, Camera.names.length returned 1 nonetheless.
* The other is to check if (Camera.getCamera() != null).
If I understand it correctly, 'getCamera' is specific to Actionscript 3. My whole project is in Actionscript 2, I'm afraid it's too late to switch. The AS2 equivalent would be (Camera.get() != null). But I tested that on my 'blind' system and again, it didn't return null.
In short, both these methods indicated the presence of a webcam where there was none.
So my question is:
Is there a really foolproof way to detect the presence/absence of a webcam in Actionscript 2? Before the 'allow/deny' dialog pops up?
actionscript but have managed to load an external .SWF file into an existing flash file.I have a button that runs the following code which successfully removes the loader:
removeChild(myLoader); SoundMixer.stopAll();
My problem is that if I click to go elsewhere my loader keeps playing.What code can I include on all my other buttons to unload the loader before going somewhere else in my flash file? I've tried just running the 2 lines above but get an error because sometimes myLoader doesn't always exist.
So i have a timer running infinitely time, and there are 2 things that can trigger the timer to stop and be removed, and both scenarios can occur, so I need to check if the timer is on before trying to stop and remove it. How can I check whether a timer exists and/or is running?
In flex, how to check if a variable exists? I have tried using
if (this['some_variable'] != undefined) { //do something }
There is a run time error saying the property some_variable does not exists. I have checked with null instead of undefined, still the same error.
Based on the replies I have used this.hasOwnProperty('variable_name'). I found that its returning true if variable_name is a public but false if its private/protected. How to check for a private variable?
I need to access information in my XML. The information I need is not stored on every object in my XML, only on the parent. But how can I check if there is a parent or not, so it wont throw an error when selecting the first object in the tree (having no parents)?
Well, I looked at the example, and looks like that was still not what I wanted. Interestingly, I took the middle for loop out and now it appears I am not having issues anymore.[code]
check to see if a node exists in an XMLList object. I have a list of objects to convert to XML, but if an xml entry already exists, then the following objects with the same name get added as children.
I'm trying to check to see if an object exists by using a simple if statement.
if (object.name) { //Do this }
However, if the object doesn't exist, I get this error, "Error #1010: A term is undefined and has no properties" - which I understand is because the object doesn't exist. Is there a better way to check to see if an object exists?
I am trying to avoid this error:TypeError: Error #1010: A term is undefined and has no properties.It is being caused when I reference an object that does not exist. My code automically goes through an array of objects and will sometimes try to reference a location that does not exist (like [-1][6] for example).I am trying to set a variable based on another variable from an object in that array like so:ob.upleft = Map.baseTileArr[ob.upY][ob.leftX].walkable;If it does not exist, my program stops and I am thrown that error. My question is, how can I check to see if that object's variable in the array even exists before assigning the variable?
I've tried this, but it did not work: if(Map.baseTileArr[ob.upY][ob.leftX]){ ob.upleft = Map.baseTileArr[ob.upY][ob.leftX].walkable;
