I was just wondering is it faster and better practice to remove stuff that is invisible from the displayList.
e.g if i have 100 objects that sometimes are visible, sometimes are not. would removing the objects from stage give any speed boost compared to simply setting them visible=false;
If I have a MovieClip with its "visible" property set to "false", would it aid performance to "stop()" its timeline? Or will that have no effect, since its not being rendered, anyway?
View 3 Repliesif I have various items on stage that I want to appear later, is it better to set .visible to false than setting the alpha to zero? For instance, there is an object that I want to fade in from alpha zero to 100%...when the object is invisible, should I just leave it at alpha zero, or should I set the visibility to false to help with performance. Does it make a difference? Would it further help performance if I removed the object using removeChild when I'm done with it?

I have a problem with my flash application because after a while that it is running, it eventually starts to slow down. My application involves something that needs to be replicated with the addChild() method. I've read some info on the internet which states that the cause of the slowing down or the lag in the application is that the removeChild() does not remove the child from the memory
View 2 RepliesI have a combobox in a view that receives information about application state changes, and then is supposed to show or hide it's children based on the whole application state. It receives state change messages, it traces the correct values, it does what it's supposed to do, however, it just doesn't seem to work. Essentially, all it needs to do is hide a combobox during one state, and show it again during another state.[code]

I have an app that displays XML as items. I am taking the createLayout() and trying to create a class that i can call from my custom component rather than having tons of code in the same file. The issue i am having is that when i call it, and run/debug, the display objects (text,links,date..) all have their visible property set to false. This happens even though I set the property to true in my code.

Every time I change the visibility of the child element I want that the parent (s:VGroup) will change his height. How to do this in flex?

I am trying to use the _visible property of loaded swf files to trigger the opening animations of these files to prevent the animations from playing before the preceding swf animation finishes. The problem is that the property of the loaded swf files read true when false and vice versa. If you click the link again, the property reads correctly (false when false etc). The onEnterFrame handler seems to be the issue, but I need it to read the property. The code is a bit lengthy, but I posted it for reference sake.

// or visible property to trigger the opening animation

View 4 Replieson frame 1 I've got 10 movieclips and each movieclip has a toggle button to make it visible true and false.
How do write the script to do the following on frame 10?
if only 1 movieclip is visible make one_mc visible true
if only 2 movieclips are visible make two_mc visible true
if only 3 movieclips are visible make three_mc visible true
... so on for all 10 hope this make sense.
In Flex I've got a component, which is based on a Canvas.It looks like this (I removed the <mx:Script> for better reading):

If I set customComponent.Visible to false, the component gets hidden (as expected). But doesn't trigger the hideFX at all. Am I doing something wrong? Or isn't this the correct way to use hideEffect and showEffect?

View 1 RepliesI have a container with children that needs to be replaced by other periodically. Those children are sprites and they have one weak referenced event listeners for MOUSE_DOWN event.When I call removeChild on children, numChildren from container decreases to 0 but they are still visible in flash. I even tried to remove container and recreate new one but it still doesn't work. Also tried to add some dummy simple sprite instead, without any event listeners but it didn't bring any results. I presume that garbage collector is not working as I wish :)Here is my code for creating sprites:
itemHolder=new Sprite();

I have an intropage with two mc buttons that resides in another mc. They are for an English and a Dutch part. So when I click on either one of them, they go to the "Home" label (frame 2). But now at the same time when the main timeline goes to "Home" I want the movieclip container that contains 6 buttons (The English or Dutch ones) to be visible false or true when I click on one or the other. As a part of the code will show some of you there must be an 1119 error that I can't figure out. It has to do with the FrameLabel that is supposedly undifined. [code]If i remove the if statement and just put the visible statement that also gives an error.But maybe the conflict could be that btnTxtFrameN_mc nor btnTxtFrameE_mc exist on the first frame where I wrote the code and only appear as from label "Home" (second frame)
View 9 RepliesHere is what I want:
1) a sprite with a rollover/out tween, going from alpha 0 to 1 on rollover, and back to 0 on rollout (let's call it "containerSprite"). That part is cake.
2) another sprite within the container (let's call it "closeButton"), that goes along for the ride (i.e., its alpha gets tweened along with the container). That's easy enough to do by making it a child of "container". When I say it is "within" the container I mean in terms of x/y.
3) when I move the mouse within containerSprite and onto closeButton, I want the container to stay visible (easy enough by setting mouseEnabled or mouseChildren to false). But I want closeButton to respond to mouseDown events, so I can't set it to mouseEnabled=false, nor can I set containerSprite.mouseChildren=false.
4) there will be several other sprites within the x/y of containerSprite, each with their own rollover/out tween. The catch is, when the mouse is within containerSprite and rolls onto one of them, the alpha of containerSprite SHOULD tween out (unlike when rolling onto closeButton).
For the life of me, I cannot get it all to work. I can get the desired behaviour in (4) easily enough, either by making the other sprites (mouseEnabled) children of containerSprite, or by making them siblings of containerSprite but higher in the display list. But the desired behaviour in (2) and (3) is vexing me: if closeButton is a child of containerSprite then its alpha tweens along with containerSprite (desired), but because it must be mouseEnabled, moving the cursor onto it triggers containerSprite's rollout event (undesired). If instead it is a higher sibling of containerSprite rather than a child, it has the same problem: if it is mouseEnabled, moving onto it counts as a rollOut event for the container. It seems like the solution ought to be easy, and I'm just missing something that is in plain sight.
Is there a performance and/or memory usage difference between these two scenarios?
Scenario 1: N visual elements all added to stage;
N-1 have visible = false, 1 has visible = true;
Scenario 2: N visual elements, only 1 added to the stage at any time.
