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,
Quote:
var mcRef;
var mc:MovieClip = new MovieClip();
this.addChild(mc);
mc.name = 'mc';

if i have a movie clip with an even listener attached to it, is the event listener being removed automatically when the movie clip is removed from the stage or should i always remove the event listeners manually?

I have two FLV files playing on the stage. The main FLV is instance is: MyVideothe 2nd is MyVideo2I have imported the videos using the wizard. The 2nd video is just a movie I created in Affter Effects that says...loading please wait....this is a really nice video and I don't want it to just use a standard preloader. Anyway, the goal is when the playback for "MyVideo" begins I would like "Myvideo2" to = visible = false;I have tried this many different ways and have been unsuccessful. I am obviously a newb at this. Also, does anyone know where I can get a list of all available eventListener actions...etc?
//var nc:NetConnection = new NetConnection();
//connection_nc.connect();

The problem is with smallImg_mc. Later on when it is clicked, it gets removed using the removeChild(smallImg_mc) command, and my question is how do I signal it through an if statement where it says
if (smallImg_mc.visible !== false) {
setChildIndex(smallImg_mc,1);
setChildIndex(logo,1);
}
It's causing annoying output errors.
I have some MXML elements which i would like to remove and add to a parent element. Unfortunately I am constrained to removing the MXML object as this is handled by the custom component. So is there any way to reinstate a removed MXML element back into the display list?
View 1 RepliesI have six objects which are on the stage when my game loads up. I have stored them in an array in my Document class. Occassionaly I run through this array and check if something has hit these objects and remove them if so. i don't actually remove them from the array though. I'm finding though that even after these objects have been removed from the stage, the hittestpoint still returns true when something crosses the area where these objects once where?! Doesn't the object have to be there for hitTestPoint to return true?

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 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?

I read some articles about ActionScript's weak references. There are two types.
Trick with Dictionary class.
EventDispatcher class.
I expected weakly referenced object to be disappeared immediately when last strong reference removed.(regardless of GC behavior) But those tricks didn't work like that. The object referenced only weakly still live a while, and looks disappear when next GC time.Removing all of strong references didn't make weakly referenced object to be disappeared from object graph.(I know it'll not be deleted immediately)
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) {

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'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 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:

I have a movieclip that contains two frames, each frame contains a different set of buttons.
it seems that i cannot add the event listeners to buttons that are not in my current viewed frame.
so.. problem one: is there a way to add event listeners to all the elements in the movieclip even if the elements are in a different frame.
problem two: after I added an event listener to some elements in current frame and then I move forward to the next frame and go back to the same frame, all the event listeners are removed and i need to initialize them again. is there a way to resolve the issue without the need to re-initialize the event listeners ?
On one frame I add a child:
ActionScript Code:
var insert4:spin2MC = new spin2MC();
insert4.x = 490;
insert4.y = 380;
addChild(insert4);
setChildIndex(insert4, 12);
This MC is communicating with other MC's on this frame. It is for example placing MC hitspider at the same x as itself on EnterFrame.
[Code]....
But it still gives me an error. That it can't find the hitspider MC. Which is true cause it's not there. But since I removed the child why does it still look for this MC hitspider?

I've got a shell movie clip which loads some other clips. In one of the sub clips, I have a key listener. Inbetween loading of the sub clips, I have it removing the key listener and the movie clip.
But the function that was attached to the key listener is persistant, even after the sub clip has been deleted, and I've attempted to remove the key listener from the main shell. What ends up happening is the second time you load the sub clip, it runs the function *twice*, or three times, or as many times as you click the link to load it.
When i run the shell movie, it shows trace actions from the sub clip even after it's been removed!
i need to be able to check if a child has been removed. is there some kind of event listener for this, or is there some other way of doing it?
