In my script I create a button that when clicked, creates a blue square. However, I want to remove any blue squares that exist before creating the new square (because as it is a low opacity square creating another one will make it more solid, as well it's just more objects that the system has to keep track of).Here is my code:.as
ActionScript Code:
package{
//importing required classes for this to work

I have a name for the object, but it doesn't seem to work.Anyone know why this doesn't work?
Code:
if (sprite) {
removeChild(sprite);

I'm attempting to make a platform game. Each level is contained within it's own MovieClip, which has it's own class. Each of these classes extend the Level class, which provides basic functionality for all levels.
Each individual level has a numPlatforms variable which stores the number of platforms in that particular level. I currently have a for loop that runs from 1-numPlatforms and sets the level area (the image, more or less) the platform contains:

Is there any way to check if a variable exists within a MoveClip? I've trying comparing it to null and also to undefined, but neither works.
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.
[AS]
if (MovieClip.mainPicArea){
trace("exists");
//removeChild(mainPicArea);
[code]....
When I test, it comes back with the trace "doesent exist", even though it does exist.

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´m trying to check if one xml element has a child-element or not, i´ve tried things like if(myxml.doubtelement != null) ; if(myxml.doubtelement != undefined) ; and if(myxml.doubtelement != 'undefined') wich where the solutions i found in forums... but they don´t work at all. i´ve been looking at the xml methods and i found contains() method, but I found out that it works with the element content and not with the node itself.

View 2 RepliesI am trying to check if a MC is on the screen but it says: 1120: Access of undefined property newBullet.
The code that is giving the error is in engine.as
Code:
if(stage.getChildByName(newBullet)) {newBullet.y = gtip.y;
newBullet.x = gtip.x;
}
gtip is an instance name of a movie clip that is in the character when it gets loaded.Here is the code from the files;
Engine.as
Code:
package code {
import flash.display.MovieClip;
import flash.display.Stage;[code]...
My situation is thus: I have an XML file with entries, each of which contains a handle (linkage ID) to the movie clip that represents that entry onstage. So I dynamically load these symbols in from the library accordingly. Only problem is, I need to be able to count how many of those entries are valid, that is, how many of the XML entries have handles that actually do correctly correspond to the names of the symbols in the library. So right now in order to count the entries I am using the value of how many entries were in the XML file but this is wrong, I need a value of how many entries in the XML correspond correctly to a library symbol.
As it stands now, if all the names in the XML file match those in the .fla, all is good. Otherwise, issues. The thing is, I want this setup to be robust so the program takes responsibility and resolves issues if there are errors in the XML. Now, the only way I can see to fixing this simply, is if there is a way to check if a symbol exists in the library -- without actually trying to load it. That way I can count just those symbols from the XML file that also do exist in the library.
in AS3 to check if a file exists before loading it. There was not very much about so I wrote these classes to do it. There are two classes, the FileLoaderUtils and the UtilEvent. the FileLoaderUtils has the function doesFileExist(url:String) and when called the class uses the URLStream class to attempt to load the file. If the file exists a UtilEvent.FILE_EXISTS event is dispatched. If the URL is incorrect or the file doesn not exist a UtilEvent.FILE_NOT_FOUND event is dispatched.

View 1 RepliesYou all know the "loadMovie" command but is there a way to tell if the movie you want to load really exists? For example: I have a movie on my server names "asdf.swf" and I want to use loadMovie to open it. Well what If I want it to check if it exists before I try to load it? Also, can you load picture files to a movie? (gif/png)
View 3 RepliesI have a form that is being created at the point the user clicks on. The algorithm is checking to see if a form exists in the same spot- if it doesnt, new object is created, if it does- result is traced. If no objects are on the stage- a new object is added. For some reason in this code- I get no results for the Mouse_Down event on the form itself. Method being called in main timeline:

the example is this, wich i am trying to remove a movieClip wich is 'mc' by clicking button, but after i click it, the object mc is still traced every time the startTrace initiates, that means its still there right? im using flash cs4,

can I check if a movieclip has a function to call it just when it exists?
View 1 Replies why this does not work? There is an empty Canvas and a Button. When the button is clicked, it creates a new Image and adds it to the Canvas - which happens. But when I click on the Image to drag it, Flex throws this error.1009: Cannot access a property or method of a null object reference.

I'm trying to:Jump from frame 1 to a frame later in the main timeline Reference an object that exists on the stage in that frame, but not in frame 1
Like so:
ActionScript Code:
function endGame():void {
gotoAndPlay("gameOver");
scoreField.visible = false;
}
A movieclip with the instance name 'scorefield' exists in the "gameOver" frame, yet for some reason, I just get a "Cannot access a property or method of a null object reference." This code is all within a function. By the time the reference to scoreField is executed, the timeline is at the right frame.
I have strange problem. I remove sprite object from container and its not visible anymore but still behaves like its existing. here is how i add object to container:
[Code]...
I think that all listeners and vars has been removed from the object but probably not because GC does not remove the object comepletly. Why object is still at its place ? Is there easy way to check what has to be removed from object so GC can collect it?
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.
View 2 RepliesI'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 developing a flash application for a website I have no direct access to. The flash application is supposed to call a javascript function on the website, defined by the website publisher. I got advised to check for the existance of the javascript object before calling its' function from actionscript:
var ok:Boolean = ExternalInterface.call(function() {
return typeof customObject !== 'undefined'
}
[code]....
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;

I have a weird problem. An Object is being passed to my function, and some parameters are optional, so naturally I would check to see if they are there, and if not, do nothing.However, I'm getting a null reference error (#1009) when I'm just checking it. Here's the sample:
public function parseObject(params:Object) {
if (params.optionalParam)

How can I check for the presence of something on the stage? I want to disable mouse clicks on the currentTarget while an image is loading, and I'd like to use the presence of a progress bar as the determinant to proceed.
Code:
If (progressBar is somewhere on the stage)
{
currentTarget.mouseChildren = false;
currentTarget.mouseEnabled = false;
}
I want to do something like this in Actionscript 3:
if(variable is Object) ...;
else ...;
Where variable could be a String(), Number(), Array(), Object()...Currently the above check returns true for all of these types, which makes sense. I only want it to return true for objects made with new Object(), however.
I have a spinning sphere, built using the away3D engine, it is wrapped in a bitmap. I need to be able to check the color value of the pixels in the sphere, however BitmapData only plots the 2D image, not the 3D sphere. So, the values become wrong. If I try to apply it to the sphere I get nasty errors. I have literally been stuck on this for days.
View 1 RepliesIs there a way to check whether a loader object is in the process of loading something? I need to create an if statement that checks if the loader has an open connection. So far, what I thought of is:
ActionScript Code:
if(loaderInstanceName.contentLoaderInfo.bytesLoaded > 0)
{
// do something
}
Here, I'm just assuming that if bytesLoaded is greater than 0, than it's probably loading something. But I don't think it will revert back to 0 after the loader finishes loading an external resource. So after that, bytesLoaded will always be greater than 0 even though it isn't in the process of loading anything. Is there any other property that I can use which says whether the loader object has an open connection?
I want to check whether the color = a certain color then appropriatly react. This is done in flash AS3.
the code I've got is
if(cal_mc.color == 0x0000FF) {
p1score = p1score + 25;
(cal_mc being the object)
It executes without any errors but doesn't work. Can anyone tell me what I'm doing wrong with the if statment?
