ActionScript 3.0 :: How To Remove Child (Ball) From Stage
Nov 4, 2009
I have a movie clip on the stage with the instance name "ball". In my code, I addChild(ball) to a Ball object called "mainBall". After doing that, I want to remove "ball" from the stage. Finally, I add addChild(mainBall) to stage. The code takes place in my Document class:
var mainBall:MovieClip = new Ball()mainBall.addChild(ball)stage
.removeChild(ball)addChild(mainBall)
From the code, I get the error: "The supplied DisplayObject must be a child of the caller".

I created movie clips that I want to add to the stage (from the library) by the use of buttons. I have a total of six buttons (and six moviclips) but I am trying to get the first two to work before I move on to the next buttons. The problem is I can't seem to remove the movie clip when another button is clicked, or the same button... Like I said I am new at this and I think a created a mess of things... I am getting error 2007 now
import flash.events.MouseEvent;
import flash.display.MovieClip;
mix_btn.addEventListener(MouseEvent.CLICK, addbear);

I am trying to remove a swf that I import to the stage, but it is not working.
Code:
function btn_cima_3call(clickEvent:MouseEvent):void{
page = 5;
esconder();
content.gotoAndStop(page);
ld.load(new URLRequest("trabalhosV0.swf"));
ld.x = 0;
ld.y = 100;
addChild(ld);
}
So when 1 button is pressed this swf is imported to the stage. but im now trying to remove this when another button is pressed and it isnt working?
Code:
function btn1call(clickEvent:MouseEvent):void{
removeChild(ld);
page = 1;
content.gotoAndStop(page);}

I'm trying to use a variable to remove a child from the stage and I get this error:
Scene 1, Layer 'action', Frame 108, Line 471067:
Implicit coercion of a value of type String to an unrelated type
flash.display:DisplayObject.
What I'm trying to do is to link some keys to add movie clips to the stage. But I need to have only one movie clip at the time on the stage, so, if I press a key to add a movie clip on the stage, the one that is already there needs to be remove. So I set a variable called "actualConf" to hold witch movie clip is on the stage. I simplified the code a bit to add it here (If I press "Q", the movie clip "lise" is added to the stage, then if I press "W", I want the movie clip "lise" to be removed than "nancy" to appear), I added a comment where I get the error :
Code:
Select allstop();
var actualConf:String = "null";
var lise:mcLise;
var liseX:Number = 50
var liseY:Number = 50
[Code] .....
Because I will have about 15 keys linked to 15 possible movie clips, I don't want to use the "if" condition 15 times.

I have a map with various regions as movieclips. When you mouse over a region, a sprite appears containing xml data. Among this data is a hyperlink. I want the sprite to stay on the stage until one of two
things happens:
- you mouseout of the sprite
- you go to a new region
That seems to be the problem. I've successfully coded the program to remove the child if you mouseout of the sprite. But if you go to a new region, it makes a new sprite and now you have two sprites with xml data on the stage! If I remove the child when you mouseout of the region, then the sprite won't stay on the stage for you to click the hyperlink. How can I make the sprite stay on the stage until:
- you mouseout of the sprite
- you mouseout of the region IF you aren't on the sprite

I am using the following code to generate a bullet (I have a bullet it the library linked Bullet):
ActionScript Code:
function createBullet (bulletSpeed:Number, startx:Number, starty:Number) {
var bullet:MovieClip = new Bullet();
bullet.x = startx;
[Code].....
upon the bullet.x getting to less that 50 it deletes the movieclip ok (other instances of the bullet are still onstage, which is what I want) but it gives the error:
ActionScript Code:
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
at flash.display::DisplayObjectContainer/removeChild()

if I add a clip to the stage as a child and remove the parent and set the parent equal to null, does the child get collected and removed from memory? What if the child has an image loaded into it as its child?
In my application I'm loading a series of png images as overlays that can be tinted for customizing in this app. When I trace my memory, the basic app idles at 64,000 k. The exact second I load those overlay images it goes up to 205,000k. If I remove those clips and "clear" the stage I should go back down to 64,000 k if everything is removed and collected correctly, right? It's not, it's hanging at 215,000 k. Are my images being cached and that is the reason for the memory staying up? If so, how do I prevent that. Or upon removing the parent of the image how can I un-cache the image.
If a user switches between models and loads several different items then the application actually crashes the Flash environment because of too much memory usage. It also does the same to browsers.

I have this class below I created that shoot's balls at the screen when a user clicks either the A or B button on their Wiimote. When it hits a target, which is detected onBallEnter-it then finds how relative the scaling is and if it's equal or greater, it removes the Event Listener, and removes the child from the parent object. Unforntually, It does neither. When it hit's this section it deletes the target (which is shot at by the ball), which is referenced at target.terminateObject(), but it does not delete the ball or remove the listener.

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.

var gravity = 2;
var speed = 0.03;
var ground = 300;
Object(this).ball.addEventListener(Event.ENTER_FRAME, fl_bounce);

When I bounce a ball off the walls of the stage using the following technique.[code]Not only is the ball jumpy and skippy. but after so often it begins to go either in a vertal motion y = 5; x = 0; or a horzontal motion x = 5, y = 0. And stays that way. Why is it that the first method works fine but the other method works terrible. Could it be because the Math.cos and Math.sin returns very large decimals.I really prefer to use the second method.

I tried to modify this code so:
1- The boarder of the ball hit exactly the the boarder of stage
2- When the ball hit any boarder of stage it go in reverse way in different directions
Code:
stage.frameRate = 30;
ball_mc.addEventListener(Event.ENTER_FRAME, moveBall);
function moveBall(event:Event):void {
if (ball_mc.x < stage.stageWidth - ball_mc.width + 40&& ball_mc.y < stage.stageHeight - ball_mc.height + 30) {

I have recently started Learning Actionscript 3.0 out of my own interest. I was trying on making a ball bounce off the edges of the stage using the Actionscript 3.0. But the code not working. The Ball happens to move on X and Y, till it hits the end of the stage, and then it just does not reverse its direction to give the effect of bounce, it gets stuck to the X axis and moves out of the stage. I tried to make changes, but failed.
Code:
function bounceBall(evt:Event):void {
var vx:Number=Math.random()*10+5;
var vy:Number=Math.random()*10+5;
var radius:Number=mcBall.height/2;
var top:Number=0;
