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: mouseInterval = setInterval(changeAlpha,10); 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: 1120: Access of undefined property mouseInterval
[URL] i want the object to fade out but in the object there's a lot of overlapping pictures and each becomes half transparent. how to make the movieclip to change the alpha as it was without objects?
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.
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?
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.
I have been checking out the following tutorial:on how to adjust the volume with a slider.it's great!what I'd like to do is use that same slider to adjust the alphaof a movie clip.is that possible?or maybe adjust the alpha of a symbol.what i'm trying to do is create "mood lighting"where the user can move a slider and lighten or darken an interiorspace, by adjusting the alpha of a dark square on top of the scene.
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.
I'm blitting a map onto the screen with tiles.. and the source of these tiles are BitmapData objects.I know you can change the alpha of a bitmap.. but I'm not too sure if it can be done on the BitmapData object itself.I want some tiles to have less alpha than others. Applying the alpha to the Bitmap.. makes everything on the current screen have an alpha.. but I only need one tile of it..
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.
The thing should work like this: theres a movie clip in frame 10 of the timeline with two buttons inside, by clicking one of them the movie should jump to frame 15 and take the alpha of two Mc there (they are inside a different movie clip) to 0. This is what ie been trying (code on the button, btw):
on (release) { McScene2.lettuce._alpha = 0; McScene2.pumpkin._alpha = 0;
i really can't belive i'm asking this, but i've been about an hour trying to look after a solution for this but I couldnt find nothing. i'm trying to change a movieclip's alpha when the swf loads and when I press an existing button. the problem is that that movieclip is inside a button and as3 has a problem with it.
this is what i am trying to do in the first frame of the first scene.
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)
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.
I have created a finite menu and it works fine, the only problem is that now I want to have the menu set to 50% alpha and when the user moves the mouse over the menu it gradually increases to 100%, Since I have never messed with Alpha's using action script.
I've been playing around with the presentation screens and slide in Flash, from browsing the web there seems to be very little if any information of how to control MC's within different parts of a presentation i.e. removing them or changing alpha. I've loaded an MC and now I'm am trying to remove it from the stage been experiment on the same slide and I just cant seem to get control of it.
I was using _root.slide1.intromc._alpha = 0; But this doesn't work for. How I can get access to MCs in a slide if its possible !!!!
I tried all zooms, placing objects outside there to gain scroll access, but it won't, and seem to be outside of some lighter gray plate... is it simply the limit? how the hell can I design the rest of my level?
I have wrtitten some code that draws a couple of lines with changing alpha and width whenever the mouse is moved. I need to convert this code to AS3 so that I can use it in conjunction with some video tracking.
Code:
var speed:Number = 100; var myNumber:Number; var myMax:Number = 50;[code]...
I have a web page which has a SWF file embeded. I have an issue with the focus.
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 )
This is happening only in IE 6.0 and IE 7.0. Below is the live example. [URL]
- 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?
When debugging, I see an objects memory reference next to its value. Is it possible to get that as a string or assign a variable based off memory location?
var myInt:int = 5; debugger shows(@afff222) var copy:int = memor(@afff222);
So basicaly the object is removing it self from the parent object,but I still think that it exisits in memory and doing its backend job.How can I remove it completely from memory?
I am getting problem of memory of having repeating object. Below is my code.
import flash.system.System; var counter:Number=0; var systemMemory:TextField=new TextField(); systemMemory.x=200; stage.addEventListener(Event.ENTER_FRAME,showNext); function showNext(event:Event){ [Code] .....
Above code does repeat textField Object continuously. Now I want to destroy previous created textField Object. So that my memory will not be hang. I got some where in the blog that with System.gc() could clear garbage collection. But currently I am not working with system.gc any more I want to clear previous object in programatically way. Is there any way that I could destroy previous created object?
There are a number of posts on here about merging XML with Java, but I can't seem to find any reference to Actionscript for the same task. I have a group of XML files that I need to load. I want them to sort into one XML Object in memory. For example, let's say these were my XML files:
