Flash :: Do Playing MovieClips Cause A Performance Hit If Visible Property Is False
Jun 10, 2010
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?
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 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?
if 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?
When the checkbox (cb1) is clicked the "my_Dyn_Txt1" is visible. The problem I'm having is - when I move forwad and back in my frames the checkboxes which were clicked are not visible due to
Code: my_Dyn_Txt1._visible = false
How can I make ("my_Dyn_Txt1"), a clicked checkbox STAY VISIBLE even after I move forwad and back in my FLA frames?
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.
I 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.
CS5.5: Does animated movieclip still animate when visible=false?I'm trying to save as much processor resources as possible to reduce lag of an iphone/computer app.
I am working on a school project using arduino and flash.
I am using motion sensor to make a movieclip symbol visible and invisible. I want to play a sound when symbol.visible = true and then turn it off when it is false.
I tried using gotoAndPlay but it said the method was no long supported? so I couldn't do that.
I want that the s:VGroup container has the height only of its visible children. In this example there is a free space even the visibility mx:HorizontalList is set to false. 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.
// the purpose is to unload the content and use the width property // or visible property to trigger the opening animation // of the next swf file onSelfEvent (load) {
on 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.
i have a tabbar with 10 button. when i change the some buttons visible and includeInLayout property false then tabbar size is not change..it is same as when it has 10 button
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)
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.
This was something I looked at a while back but couldn't figure it out. Now returning to give it another go.Basically I want to find out how to check if a movieclip is visible under a mask.I've got a row of thumbs in a movieclip under a mask. Some are out with the the masked area so I've got some script to make the movieclip scroll the other thumbs into view of the masked area. Is there any code I can apply to the thumbs to check if they are in or not in view of the masked area?
I used the following code to read a file "images.txt" and build a movieclip by loading the images specified in the file.
I wanted to make this dyanmicaly built movieclip invisibe. i.e "setProperty (_root.preloader['part'+count], _visible, false);" line in my code below is not working.
