Flash :: Remove A Child With Enterframe Running?
Oct 21, 2011
Whenever I try to remove an object/child with enterframe running I always get null reference error.In my particular case, the setup is Battlefield contains a lot of Robot:
A child (Robot) dispatchEvent that it is destroyedThe parent container receives the event and starts removing the child by removeChild and remove the child from an array of Robots.on enterframe, during a loop to move the robots around, sometimes I would get null reference, so I have to call if (robots[i] == null) continue;
How do you safely remove the child without sprinkling if robot is null all over my enterframe?

I am trying to create a simple play, stop, rewind. fforward controller. I have the slideShow and the Control in the same time line. As the enterframe event is nested inside a function it will rewind but then none of the other buttons will work as I am not able to removeEventListener for the enterframe event.

i'm new to AS3 and i was wondering what is the best way to remove a child at a point. i tried Holder.removeChild(Holder.getObjectsUnderPoint(new Point(exampleX, exampleY))[0]); however that returned ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

I have an issue where removechild won't infact remove a child. I think its something to do with my dropTarget.parent issues. The concept of the code is that you drag a source onto a destination. When you drop the source onto the destination you will get a text field that says "Hello" or "Goodbye". The objective i want to achive is that once i drop a source onto the destination, removechild will remove any previouse textfields added. This is proving difficult.

So try running a test where you've placed several copies of a movieclip on the stage in the authoring environment and then linked the clip to this class:
Code:
package {
import flash.display.*
import flash.events.*;
[Code]....
The first clip will remove itself but the rest won't. The trace statement in the contructor isn't even executed which indicates that the other clips aren't even contructed.
So I suppose Flash has some method of contructing all the clips which were placed in the authoring environment and it involves counting the clips and noting their position on the display list. So removing a clip during the process of constructing them will disrupt the process by altering the display list.
But it gets even weirder. Try adding a click event listener to the stage. The clips won't respond at all. But it's not like they're just not mouse enabled, because if they were then the stage would still respond when you clicked them because you'd be clicking what was behind them. Instead they block any mouse events from reaching behind them. So not only are they not constructed, they obstruct any mouse events from occuring in their space, and they're still visible.
I also just discovered that the same applies to all clips that are to be contructed afterwards, regardless of whether they're the same class.

I am working on a website right now, which involves using framescripts to invoke instance methods from the document class. These methods are supposed to trigger the new content of each page, e.g. a galleryCreate() method that creates an instance of a custom Gallery class. The other job that this method must perform is run a check to see if there are any other children that need to be removed prior to trying to bring up the new content (for example, to prevent multiple Gallery instances from being created, or a Gallery instance being created when a Newsfeed instance is still on the display list).
This was the solution I tried:
script on frame labeled "gallery":
ActionScript Code:
galleryCreate();
Script in document Class after the main constructor. Spaceball is an empty MovieClip declared at the beginning of the class as an easy point of reference to the root.
ActionScript Code:
public function galleryCreate () {
if ((spaceball.parent.getChildByName("gallery")) != null) {
trace("An instance of the Gallery object was found and deleted");
removeChild(spaceball.parent.getChildByName("gallery"));
} gallery = new Gallery();
addChild(gallery);
}
When I ran the program, I clicked on the button to the gallery page, and the gallery came up alright. However, when I clicked on it a second time, I could see from the alpha of some of the elements that additional classes were being placed on top of the original ones. The trace in the if statement was never registered. So to troubleshoot this problem, I inserted the first two traces into the beginning of the galleryCreate() method, and the last trace at the end.
ActionScript Code:
trace(spaceball.parent) //returns [Object Body], Body being the document class
trace(spaceball.parent.getChildByName("gallery")); //returns null
//after Gallery has been instantiated in the new gallery object
trace(gallery.parent); //this returned [Object Body]
Running the program again, the trace(spaceball.parent.getChildByName("gallery") would consistently return null, followed right after by a trace that recognizes the parent of the newly instantiated Gallery object to be the Document class. Doesn't that mean that it should be recognized as a child during the second iteration of galleryCreate()?

I've only started using Actionscript 3 recently and am having difficulty removing a number of childs from my flash game (a variant of frogger). My aim is when the player's character (WWalk) touches the EndGameZone on the other side of the stage, the generated Lorries should disappear, so I can put an ending animation on scene two. I can get it to load Scene 2 but cannot get rid of the lorries - They just stay still and don't disappear.
Code:
stage.focus = stage;
//adding keyboard control over the character to control direction
stage.addEventListener (KeyboardEvent.KEY_DOWN, CWWalk);
function CWWalk (e:KeyboardEvent) {
switch (e.keyCode) {

I have a set of swfs that open one on top of the previous as buttons are pressed. Thing is, once you've pressed buttons so many times that there are a ton of swfs on top of one another, the browser begins to run slower.
Is there anyway to remove all the swfs under the current swf in the code without disrupting the running of the current swf?

Is it possible to start a seperate flash application from a main flash application. I really want it to be like how a messenger works... where the chat window is independent of the parent program and the user can minimize it or move it around the screen. I also need to be able to pass variables to the "chat window". I am thinking about using something like fsCommand maybe.. but I would also like the child window to be a swf and not exe file.What I got is a parent program that will be responsible for child programs The child programs will be started using variables that the parent initializes the child with (flashVar). The child window will be similar to chat windows such as Yahoo messenger.

I have an older program that I need to update. In it I there is a movieclip that displays text. Embedded in that movieclip is a timer that makes the text disappear after a few seconds. Everything worked fine before when I was using flash to put the clips on the stage. Now I need export the symbols and use addChild to display them. My problem is that the timer is starting when I assign the clip to the variable (frame 1), not when I need it to; which is after I add the child (frame 70-ish). If I were starting over there is probably a million simple solutions to this, but I am trying to not rework everything I already made to fix this seemlingly small problem.

flash and am trying to create a vending machine game but I seem to have come unstuck. The coin_slot that I have added doesn't seem to remove from the stage after frame3. I have included colour to the the event triggers to allow me to see what is happening at the moment the coin_slot image that I add does seem to remove from the stae but there still seems to be something hidden within the stage. This is still in really rough stage of development I just need to figure out the code at the moment.

none of it worked, It's just a minor cleanup really. Whenever you click a new picture you can see all the ones underneath it during the load so I just want to clear out those items or rather clear the loader before it loads something new.

I have a missile which gets fired once the mouse button is down. The main class snippet is:
ActionScript Code:
public function moveTheBullet(event:Event):void
{
if(buttonDown)
[code]....
The bullet is now flying across the screen thanks to the Rock class which control its velocity and direction. When the missile is off the screen, however, I'd like to remove it, so it doesnt eat up memory. This is how I'm trying to accomplish that (the code's in the Rock class):
ActionScript Code:
public function moveIt(event:Event):void
{
if(this.x > 200)
[code]....
But yeah, its not working at all. I'm getting the error: Error #2025: The supplied DisplayObject must be a child of the caller. how to remove the bullets.

I am making a game (surprise, surprise). In the game there are things to collect, possibly lives. I can add them to the screen but removing them is an issue. The best way I have worked out is to create a sprite called livesContainer, add all the lives to that, then, if the user returns to the main menu, I can remove all of the lives by removing that one container. Here's how I create all of the lives and add them to the stage. This all works and you don't really need to read all of it.[code]...
