Actionscript 3 :: Memory Gain Changing Alpha Value Of An Object?

Dec 30, 2011

for a periodic table tool I'm making, I've incorporated an effect that changes the alpha value whenever I hover over an element (pretty standard). I've noticed a mysterious gain in memory when hovering over my elements; using SYSTEM.TOTAL_MEMORY - there would be about 0.005MB increase in memory usage when I hover over an element, which isn't relinquished when I move my mouse off. However, if I move my mouse back on again, there isn't a second memory gain.

[Code]...

Does anyone know why this memory gain is happening when the alpha value is changed? And curiously why it only happens once? Some extra info: my Element class is a MovieClip, with a couple of TextFields, primitive variables and a MovieClip in it. It has had its mouseChildren property set to false (and buttonMode property set to true).

I am very new to Flash and I have the following script:

function changeAlpha(){ fader_mc.alpha = Math.round(root.mouseX/550*100) }
This is simply to change the Alpha of my object as I change the X value of the mouse cursor. I keep getting the following error message:

ActionScript 3.0 :: Changing The Alpha Of A Swf

Aug 10, 2010

I'm trying to create a tab system on my website. I have a small 25 pixel tall swf file at the top of the page that acts as the tabs. It uses PHP to communicate with the rest of the site. I have a larger swf below that acts as a directory to my files. When the user finds a file, he or she can open it in a new tab by clicking a certain button. And then switch between tabs using the top swf. I've got all of this down using AS3, but I'm not as good at the basic web design elements. How do I communicate to have every lower layer except for the one that the viewer wants to look at go to 0% alpha? Also, I cannot just have the tab system be all in one swf because some of the files that I want the user to open will be in AS2, which won't run inside an AS3 host.

Actionscript 3 :: In Flash Does Extending An Object Use More Memory Even If The Object's Methods Aren't Used

Jul 20, 2011

I am creating an object pool to cache some recyclable objects in memory at the outset of my application in order to avoid (as much as possible) the performance issues caused by GC running; if possible I'd like to minimize the memory my object pool reserves, so I'm attempting to pool generic forms of the objects (with no methods) and then casting the generic variants to more specific and complex object types which extend the generic form when I actually want them on the stage.

The trouble is that to do this requires the generic variant class to import/extend MovieClip (because the more complicated objects are themselves MovieClips and make use of DisplayObject methods)-- does simply importing and/or extending a class add to the memory an object takes up when instantiated even if it never uses methods from the inherited class? It makes sense that it would, and some light profiling seems to suggest that it does, but I'm not 100% certain. About how large should an 'empty' MovieClip instance be in bytes?

Actionscript 3 :: Changing Alpha Of A MC On Hover?

Apr 11, 2011

this.addEventListener(MouseEvent.MOUSE_OVER,function() {
this.alpha=0
})

In an MC, I want it to become invisible when the mouse hovers over it. The reason I'm putting this code inside the MC and not making an instance out of it is because this MC will recur numerous times. The listener does work, as tested with trace(). For whatever reason, alpha doesn't.

ActionScript 2.0 :: Changing Alpha Settings?

Apr 28, 2003

i made text into a movie clip and put in this code to adjust the alpha.

onClipEvent (load){
this._alpha=100;
i=1;
}
onClipEvent (enterFrame) {
if(this._alpha=0 && i==0){

[Code]...

The alpha is going down.I think, because the text isnt there. What i'm having trouble with is getting it to go back and forth. Increasing and decreasing the alpha when it gets to it's maximum or minimum. I hope I'm making some sense.Does anyone have any ideas? And no I cannot do this with a simple motion tween because there are things happening in the background.

ActionScript 3.0 :: Dynamically Changing Color Of MC - Using Alpha?

Mar 8, 2009

I am changing colors of an mc dynamically, in this way: I have an mc of the color green for example. What I want is it to turn to a specific color in time. I have in that mc a sprite, that is that specific color (red in this case). iIset it's alpha to 0 and put it in the layer above the green part. Now when I set its alpha to 1, it will be that colour. When I set it to 0.5 ofcourse it'll be a mix between those colours. Is it faster to do it, but changing 0xFFFFFF? I wouldn't know how to do it though. i want to be able to tell it to go 3/4 of color nr 1 and 1/4 of color nr 2, for example. i also want to be able to choose those colours specificly, for the sake of art. so just choosing 0xFF0000 for red, wont do, for artistic reasons.

ActionScript 2.0 :: Changing Alpha On Multiple Movie Clips?

Jan 7, 2010

I know how to change the alpha of one movie clip at a time on rollover, rollout, and release. But I'm a bit stuck trying to figure out how I would change the alpha of multiple movie clips, when one is clicked. It's for a simple photo gallery and I want all the thumbnails to darken once one has been clicked & the image is loading. I can't just fake it by having a somewhat transparent black movie clip appear over everything, because I need the alpha of each thumbnail to be able to change again once people roll over a new thumbnail.(a section of my code is included for reference but there are like 30 thumbnails so I didn't include it all, the code is the same for everything)

Code:

thumb_001.onRollOver = over;
thumb_001.onPress = down;
thumb_001.onRollOut = out;
thumb_001.onRelease () {

ActionScript 3.0 :: Saving Alpha Property When Changing Frames

Mar 22, 2010

i have this little display and when you click on certain items their alpha changes to 0.1, this worked fine until i added another frame with a different display on another frame. so now when you change frames and go to the new display then go back to the old display on frame 1 the alpha properties are all reset back to 1. So to fix this i thought i could simply add all the movieclips with an alpha less than one to an array when i left the frame then when you come back to the frame you could reset all the moviclips in that array back to having an alpha of 0.1. But this doesnt seem to work. here is the code i used.[code]But this code doesnt seem to work, the strange thing is even when i add some trace statements they tell me that the alpha does in fact equal 0.1 but visibally they haven't changed.

Steps to reproduce:

1)Click on a HTML Text Field which is inside a Iframe

2)Click on a Flex Field.

3)Begin to type some text.

Expected Result is the entered text should go in the Flex TextInput field but the actual Result is it goes into HTML text field.

This is the bug which was filed but closed without any resolution. The workaround suggested there doesnt work. ( bugs.adobe.com/jira/browse/SDK-12377 )

ActionScript 3.0 :: Object Not Deleted From Memory?

Oct 11, 2009

what I have is:

- listener added with weak refference, therefore it shouldn't keep the GC away

- object set to null

- trace of the object m shows null

- debugger shows the value of m as null

But the "frame" trace still keeps on appearing, so where exactly is that object and how to check for it, how to delete it and kill it. I know that listeners keep objects in the memory, but then how to find them, and at the end of the day also used weakReference=true while assigning it, so that should take care of it. What exactly is going on here?
