ActionScript 3.0 :: Check To See If Movieclip Exists Without Throwing Errors

Nov 7, 2009

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

Actionscript 3 :: Check If MovieClip Exists?

Feb 17, 2010

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")
}

and

if ("thumbContainer" in this) {
trace("exists")
}

Actionscript 3 :: Check If A Movieclip Exists On A Specific Location Relative To Event.currentTarget?

Sep 22, 2011

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
}

ActionScript 3.0 :: No Script In File But Throwing Ten Time Errors

Jul 8, 2009

I'm having a nightmare - always at the last minute of the project Flash craps out...

I have stripped all the actionscript from the file, but the animated sprites cause the following error throughout the timeline (about 5/6 times) [url]...

I changed two main elements to buttons, then back to movie clips via the library panel and the properties window. Could this 'break' the objects?

ActionScript 3.0 :: Sprite Trying To Remove Itself From Stage (Throwing Errors)

I'm trying to have a bullet Sprite remove itself from the stage once it is off the stage, but Flash keeps throwing #1009 errors at me. I've looked over the code several times and don't understand what's wrong.

Bullet code:
package {

import flash.display.MovieClip;
import flash.events.*;
public class Bullet extends Sprite {
private var bullet_direction;

Error message:

Flex :: Asdoc Throwing Errors For MXML Component That Includes A Separate .as File?

Jul 27, 2010

I have an MXML component that includes a .as file with

<fx:Script source="myfile.as" />

Running asdoc throws a whole bunch of errors like

"Error: The private attribute may be used only on class property definitions."
"Error: The public attribute can only be used inside a package."

Solution 1 is to move the AS code into the MXML file. Kind of defeats the objective of using external .as files for MXML components in the first place, so really a last resort option. Code inside a mxml file is messy (I really don't want logic mixed in with mxml), and would also require using the < !--- ---> asdoc syntax.

Solution 2 is to have the MXML component inherit from a normal class file. That would mean no private members in the base class, only internal (meaning a separate package for the component to be safe) or protected. This would make things tedious to say the least.

Are there any other work-arounds or possibly a beta/nightly version of asdoc that fixes the problem? I am using the Flex 4.1.0.16076 SDK, the "latest production quality release".

Update:Just tried using asdoc from the svn trunk, (4.5.0 rev. 16942) and the problem persists.

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.

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?

Actionscript 3 :: Check If A Variable Exists In Flex?

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?
