ActionScript 3.0 :: Check If An Element Exists In Array

Feb 18, 2009

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]

ActionScript 2.0 :: Check An Array To See If An Element Has Already Been Added?

Feb 4, 2005

is there a way to check an array to see if an element has already been added? I'm working with an XML document where there are 4 possible variables, but these 4 vars are repeated several times over. It's reading in fine... I just want to pull those specific variables out of the XML and add them to an array, but I do not want them to duplicate. To say it another way... I don't want my array to be more than 4 items long (it is possible to be less) with a max of those 4 different vars.

ActionScript 3.0 :: Check If Text Exists Or Not?

Oct 30, 2010

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

if(orderMenu_mc.Item2_txt.text == "")
{
emptyText = 2
trace(emptyText+"Hello")
}

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 have a movieclip created with the following code:

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.

trace("exists")
}

and

if ("thumbContainer" in this) {

ActionScript 2.0 :: Check If Camera Exists?

Jan 12, 2010

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?

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.
