Hi Theodore, When you say 'addChild(mySprite)' mySprite *is* the child of something: the instance you call addChild on (addChild(mySprite) is equal to this.addChild(mySprite)) To remove mySprite you have to call removeChild(mySprite) on the same instance. From the error it seems that myChild is not a child of the instance you call removeChild on. Did you trace mySprite.parent to see if mySprite is actually a child of an instance? (traces null if mySprite is not a child of anything, traces the parent if mySprite is added as a child) parentName.removeChild(mySprite) does the trick then.

Hi Theodore,
When you say 'addChild(mySprite)' mySprite *is* the child of
something: the instance you call addChild on (addChild(mySprite) is
equal to this.addChild(mySprite))
To remove mySprite you have to call removeChild(mySprite) on the same
instance.
From the error it seems that myChild is not a child of the instance
you call removeChild on.
Did you trace mySprite.parent to see if mySprite is actually a child
of an instance? (traces null if mySprite is not a child of anything,
traces the parent if mySprite is added as a child)
parentName.removeChild(mySprite) does the trick then.

Re: [Flashcoders] Finding and Removing a Sprite
Bingo!
Try this instead:
var mySprite:Sprite = new Sprite();
function createBar(dfile:String):void {
...
function createGraph():void {
mySprite.graphics.
addChild(mySprite);
}
}
function clearBar():void {
removeChild(mySprite);
}

you could also make createBar return a reference to the sprite...
function createBar(dfile:String):Sprite {

mySprite = new Sprite();
// do stuff
addChild(mySprite);
return mySprite;
}
var mySprite:Sprite = createBar(string);
then you can remove it using your stored reference to the sprite...
function blah():void

You could parent them.
Var barMom:Sprite = new Sprite();
addChild(barMom);
function createBars():void
{
for (var i:int=0; itotalbars; i++)
{
var bar:Sprite = new Sprite();
bar.name = barBrat+i;
...
barMom.addChild(bar);
{

This way at least you know where they live.

Re: [Flashcoders] Finding and Removing a Sprite: PART II
ok, bar isn't the name of the sprite, it's a variable with name bar which
contains a reference to your sprite... if you want to use names then do
something like bar.name = String(bar_ + i); but personally i'd use an
array like so...
var bars:Array = [];
function createBars():void
{
for (var i:int=0; itotalbars; i++)
{
var bar:Sprite = new Sprite();
...
addChild(bar);
bars.push(bar);
{
}
then you can get at the bars later to do stuff with them or remove them...

Re: [Flashcoders] Finding and Removing a Sprite: PART II
You could create an empty array (outside the functions)
And add each newly created bar to the array.
Afterwards, say in another function, you can reference the array
indexes.
Something like:
myBarsArray = new Array();
function createBars():void
{
for (var i:int=0; itotalbars; i++)
{
var bar:Sprite = new Sprite();
...
addChild(bar);
myBarsArray.push(bar);
{
}
function removeBars(i:uint):void
{
removeChild(myBarsArray[i]);
//don't remove the bar from the array
}

Re: [Flashcoders] Finding and Removing a Sprite: PART II
Inside your loop, you can add the sprite to a movieclip and give each movieclip
a name using the variable in your loop like:
mcName.name = mc+i; //or whatever your for loop var is
And then remove it by getChildByName(mc#);

RE: [Flashcoders] Finding and Removing a Sprite: PART II
I agree with Mr. Tom Rhodes. Storing references to your buttons in an
array is far better than trying to create and use dynamic instance
names like bar+i. You can tack on data properties to the buttons as
well, so they have information about themselves that travels with them.

Glad you got it fixed. I'm late to the discussion, so didn't
contribute anything yet--but I will now :-)
Do yourself a favor now. One of the real advantages of AS3 is
eliminating timeline code--you have to do that eventually to take
advantage of AS3's OOP capabilities.
Make a backup of your .fla before you do this, in case something goes wrong.
In the same folder where your .fla file is, create an ActionScript
file called Main.as. Inside it, use this:
package
{
public class Main extends Sprite
{
//functions go here
}
}
Now cut and paste all your code from the timeline and put it after the
line //functions go here. You can overwrite that line--just keep your
functions in between the inner set of curly brackets.
In the .fla file, in the Properties window, set your document class to
Main. Remember, ActionScript is case sensitive.
It should compile and run the same as before, but you will have taken
a good first step towards utilizing AS3's power.
Cordially,
Kerry Thompson

Re: [Flashcoders] Finding and Removing a Sprite: PART II
I think it depends on the circumstances:
If you are not manipulating the child sprites in any way, just adding
them at the start, removing at the end and possibly listening for events
on them, why would you want to use more memory by storing the sprite
instances in an array or a vector when you already have a storage medium
for them - the parent container?
If I was needing to move things around, or juggle the display order, or
manipulate sprites in the container, I may want to store a reference to
them, but if they are just display elements, it's even simpler just to
add them to a container sprite then iterate through the container when
you are done with them if you need to remove listeners.
Obviously this is purely down to coding preferences, but why waste
arrays, when your DisplayObjectContainer does it for you...

You can use the addChildAt method and tell it where to add the object in the
displaylist.
addChildAt(objectName, 0); will add the objectName to the bottom of the display
list.

Glad you got it fixed. I'm late to the discussion, so didn't
contribute anything yet--but I will now :-)
Do yourself a favor now. One of the real advantages of AS3 is
eliminating timeline code--you have to do that eventually to take
advantage of AS3's OOP capabilities.
Make a backup of your .fla before you do this, in case something goes wrong.
In the same folder where your .fla file is, create an ActionScript
file called Main.as. Inside it, use this:
package
{
public class Main extends Sprite
{
//functions go here
}
}
Now cut and paste all your code from the timeline and put it after the
line //functions go here. You can overwrite that line--just keep your
functions in between the inner set of curly brackets.
In the .fla file, in the Properties window, set your document class to
Main. Remember, ActionScript is case sensitive.
It should compile and run the same as before, but you will have taken
a good first step towards utilizing AS3's power.
Cordially,
Kerry Thompson

RE: [Flashcoders] Finding and Removing a Sprite: PART II
IMO, an array is hardly a waste of space, and allows for expanding your
app easier if need be, but you're right, could come down to coding
preferences in that case. More often though I think, the benefits of
storing them in an array outweigh the benefits of dynamic naming.

Subject: Re: [Flashcoders] Finding and Removing a Sprite: PART II
I think it depends on the circumstances:
If you are not manipulating the child sprites in any way, just adding
them at the start, removing at the end and possibly listening for events
on them, why would you want to use more memory by storing the sprite
instances in an array or a vector when you already have a storage medium
for them - the parent container?
If I was needing to move things around, or juggle the display order, or
manipulate sprites in the container, I may want to store a reference to
them, but if they are just display elements, it's even simpler just to
add them to a container sprite then iterate through the container when
you are done with them if you need to remove listeners.
Obviously this is purely down to coding preferences, but why waste
arrays, when your DisplayObjectContainer does it for you...

I agree with Mr. Tom Rhodes. Storing references to your buttons in
an
array is far better than trying to create and use dynamic instance
names like bar+i. You can tack on data properties to the buttons as
well, so they have information about themselves that travels with
them.

Subject: Re: [Flashcoders] Finding and Removing a Sprite: PART II
ok, bar isn't the name of the sprite, it's a variable with name bar
which
contains a reference to your sprite... if you want to use names then
do
something like bar.name = String(bar_ + i); but personally i'd use
an
array like so...
var bars:Array = [];
function createBars():void
{
for (var i:int=0; itotalbars; i++)
{
var bar:Sprite = new Sprite();
...
addChild(bar);
bars.push(bar);
{
}
then you can get at the bars later to do stuff with them or remove
them...

...

And see this this is where my ears start to bleed... this is
seemingly
creating, say, 9 Sprites ALL with the same name bar I need to
keep the
new Sprite() line in the loop for them to be created... but then I
need some
way to access them to delete them
Any ideas?

We're talking about only nine instances here. It would be a different matter if it were tens or hundreds of thousands, but even then the additional memory required to store another reference to them would be insignificant compared to the memory the Sprites themselves would use, and performance would be the far bigger issue. So, a descriptively named collection has a higher benefit, for readability alone. Preferably a Vector, so casting isn't necessary even when the Sprites for the bars become a proper Bar class, as they probably should. I'd still put them in their own container, though. Then the container goes on top of another with the lines. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
RE: [Flashcoders] Finding and Removing a Sprite: PART II
More than one way to get things done. Depends on your needs. Check out
DisplayObjectContainer in the docs.
var barMom:Sprite = new Sprite();
this.addChildAt(barMom, 0);
function createBars():void {
for (var i:int=0; i 9; i++) {
var bar:Sprite = new Sprite();
bar.name = barBrat + i;
barMom.addChild(bar);
}
}
function spankABrat(container:Sprite, childName:String):void{
container.removeChild(container.getChildByName(childName));
}
function eightySixBrats(container:Sprite):void {
var len:uint = container.numChildren;
for (var i:uint = 0; i len; i++) {
container.removeChildAt(0);
}
}
trace(barMom.numChildren =,barMom.numChildren);// 0
createBars();
trace(barMom.numChildren =,barMom.numChildren);// 9
spankABrat(barMom, barBrat3);
trace(barMom.numChildren =,barMom.numChildren);// 8
eightySixBrats(barMom);
trace(barMom.numChildren =,barMom.numChildren);// 0

Doesn't storing them in an array create a set of references that will need
to be cleaned up?

RE: [Flashcoders] Finding and Removing a Sprite: PART II
Doesn't storing them in an array create a set of references that will need to be cleaned up? Absolutely (if the app performance even needs cleaning up and/or the items are even removed). But that's easily taken care of with a cleanup function. So for small uses, as I mentioned, may not be worthwhile, but I am thinking long term scalability. I just hate to see people default to dynamic naming all the time when architecturally, using arrays as storage is better in the long run. For this, the dynamic naming would be fine. I'd just be careful to make it a habit for everything.

Re: [Flashcoders] Finding and Removing a Sprite: PART II
yeah, horses for courses... if you want to better encapsulate stuff, i find it easier to work with arrays (in fp10 vectors) and pass them around if needs be. tying your code to specific timelines gives you more work to do if you want to reuse that code imho. for something quick and dirty in timeline code though that you know you don't want to reuse then whatever's clever. Mr. Jason Merrill is right though about having cleanup functions for whatever you create being a great way to not getting into trouble later i reckon...
