there is a Tip: Reducing Display Object References I need help with.
if I do:
[Code]...
without removing the listener, does that still leave a reference to "myMovie" in memory?
I'm trying to get it so whenever the object is clicked it reduces in opacity by 10% each time, and if it gets to 10% and it's clicked again it stays at 10% instead of going to 0. I got it to keep going down in opacity fine I just don't know the code to keep it from going lower. this is what I have so far
function fadeOut(e:MouseEvent):void {
instrument.alpha -= .1;
} if (instrument.alpha<.1) {
instrument.alpha = .1
} else {
instrument.alpha -= .1;
}
I've been using Senocular's free transform tool: [URL] in tandem with an image upload (using the fileReference class) so that users can upload an image and the transform it.
The free transform class has a function that allows you to restrict the scaling of the movieClip that you apply the free transform to, but it works on a 'scale' rather than specific height and width properties. My problem is, that I don't know what he dimensions of each uploaded image will be, so if it's restricted to a scale, some images will be allowed to be bigger than others....
I am only at the very beginning and I want to make certain that I go through this understanding everything that can so maybe I won't have to ask as many questions in the forums and can start answering more. In this part:The code for making a standard generic object in Flash is as follows:
myObject = new Object();
The variable myObject then becomes a object variable which can then have more variables added to it using dot syntax like so.Is myObject the actual name of the variable and the = new Object simply stating that there is a new object called myObject?
I'm writing an application where I have many objects (data models) that are identified by a unique String ID that every such object possesses and these objects can refer to each other by their IDs.So far so good but now I need to keep track of which object keeps a reference to another object and of course there are cases where an object references (or is referenced by) more than one other object and I was wondering what would be the best method to store these references? In a simple map data structure I could just map one object's ID to another but as mentioned there are cases where an object can hold a ref to an arbitrary amount of other objects
View 1 RepliesDoes anyone know if it's possible to list the references an object currently has in ActionScript3 (e.g. listeners, children etc)?
I'm trying to clear an object from memory ready for garbage collection but for some reason it's hanging around.
I am trying to create an object that is handling the events of different objects. The object is created in the 1st frame of a code layer:
ActionScript Code:
var gImageEdit:ImageEdit = new ImageEdit( imgAction, movImageFront,
movToolbar.btnZoomInImage, movToolbar.btnZoomOutImage, gZoomSound );
[code].......
I'm just getting to grips now with how the Garbage Collector works.
Is there a way (like a function or a custom class available somewhere) to check an object for all its references and return them so that you can see what it's connected to?
* Is it possible to create weak references to objects (like theventListener/EventDispatcher is able to do) so that if they are removed, you won't be stuck keeping a reference and taking up space to something that should be garbage collected?* Is there any way to find out how many active variables are referencing a certain object? This would be handy to actually create weak references, since, if you for example, have a static array containing all objects created in that class, you can do a regular check to see if there is only one remaining reference, and if so, you can safely remove it.
* Also, might there be any way to list the entire space (one big chunk of binary data, most likely) of every variable currently running in the program, all references, basically, what Flash is currently storing in RAM?I'm pretty sure that Flash (as crappy and lacking as it is in so many areas) does not have anything like any of these built in, but hopefully there is at least something.
I want to do is create several arrays to hold groups of movie clips (i am using as buttons) which have similar functions so that I can add event listeners using a for loop statement rather than making a huge list of add and remove event listeners.I have seen this method working before but I cannot get my code to work!! This is probably a very noob concept but I have been struggling with it for hours.Ok, so in the extends movie clip bit on my as file I declare the array as such:public static var controlBtns:Array;Then in the initializing function I put values into the array as such: [code]The trace seems to output all the object names (as they are listed in the library) and then I get this error: TypeError: Error #1010: A term is undefined and has no properties.Which is kind of obvious as I cannot seem to access the movie clip instance names that I have set up in the array.I tried putting quotation marks around the names in the array making them strings but then I can't access properties of strings - which is obvious enough to.
View 8 RepliesI have a bit of a memory leak issue in my Flex application, and the short version of my question is: is there any way (in AcitonScript 3) to find all live references to a given object? What I have is a number of views with presentation models behind each of them (using Swiz). The views of interest are children of a TabNavigator, so when I close the tab, the view is removed from the stage. When the view is removed from the stage, Swiz sets the model reference in the view to null, as it should. I also removeAllChildren() from the view.
However when profiling the application, when I do this and run a GC, neither the view nor the presentation model are freed (though both set their references to each other to null). One model object used by the view (not a presenter, though) IS freed, so it's not completely broken. I've only just started profiling today (firmly believing in not optimising too early), so I imagine there's some kind of reference floating around somewhere, but I can't see where, and what would be super helpful would be the ability to debug and see a list of objects that reference the target object. Is this at all possible, and if not natively, is there some light-weight way to code this into future apps for debugging purposes?
I have a 2-dimensional array of Objects. Their location in the array determines where they appear on the screen. When I want to move an object down, I am trying something like this:
[AS]LocationArray[i][j+1] = LocationArray[i][j];
LocationArray[i][j] = null;[/AS]Of course, with the way AS3 handles objects and references, it removes the object completely. How can I simply move a reference (or remove an reference) without destroying the object?
loading external SWF's and its class files hanging around after the movie is unloaded....Its kind of tricky to explain, but you can see it very clearly in this file... http:[url]...Just run the main_stage.fla within flash [mx 04] and you'll see that if you click "Tester A" it will trace out "My Name is Tester A", then if you click on "Tester B" it will load a different swf, with a different class, but still trace out "My Name is Tester A" when it should be "My Name is Tester B"....
I have tried, unloading the swf's, removing the mc_Dropper and re-attaching it, re-declaring the variable testObj as null before declaring the class,
I am a new flash developer and I cannot seem to understand this problem. Whenever I try and trace one of these variables of type XMLList they all return NULL except for the last one in the array.The createDatsSets() function is designed to pull XMl data and copy it to an variable of type XMLList which resides in an array. This should happen 8 times to add data to all 8 variables.It works fine with a single variable but, in the for statement when.I try and trace any of the variables in the xmlList array only the last one has XML data in it.
View 4 RepliesI'm trying to get my head around optimising AS3 code and clearing things out for garbage collection.
I understand that each time an item is referred to in the code it has its reference count increased by one, so I was wondering if there is a trace option I can use to see how many references each of my objects has?
I can then see where things are getting left behind (if they are) and where I can make optimise better.
I think it would help me work out several issues if I was able to do this
If I create a rectangle with 100px width and 100px height and then rotate it, the size of the element's "box" will have increased.With 45 rotation, the size becomes about 143x143 (from 100x100).Doing sometimes like cos(angleRad) * currentWidth seems to work for 45 rotation, but for other bigger angles it doesn't.At the moment I am doing this:
var currentRotation = object.rotation;
object.rotation = 0;
var normalizedWidth = object.width;
[code].....
I was thinking about Flash GC the other day and came up with a question about how reference counting would work in the following 4 class scenario (assume GuiMain is the movie's document class):

I was wondering if it possible to write up some AS that will take line paths that you have drawn and convert them into a Path object? For example say you drew a jagged line from left to write, would there be a way to have AS convert that into a Path object.

View 1 RepliesCan you make one Bitmap Object (I'm using an external jpg) or something similar, and then display it many times simultaneously without creating a separate object each time?
Also, would they be easily removed or hidden?
I've got a little checkmark jpg graphic loaded here, but I'm not sure how to go about using it in many places at once.. I can only display it in the one place at any one time...
I'm thinking there might be a way to load the picture once, then use its bitmapData elsewhere in new display objects somehow, without needing to reload the image over and over?
It's my understanding that a display object cannot be in the display list more that once.So if I add something to the stage shouldn't a second addition of the same object replace the first? for instance:
[code]...
there should now only be one "myDisplayObject" on the stage.
How can i cast a object to another type? in AS3 i tried putting (objectType) infront of the variable but it doesnt work, below i have added objects of fishes into the child, and i am getting the fishes back out when mouse down is triggered, and then calling the fishes what to do. however i cant call the method of the custom class fish because it is a displayobject.[code]...
View 1 RepliesI building a website and i have animations from after effects I will be importing into flash. Any time a menu button is clicked it triggers the flash timeline and plays the corresponding anumation embedded in different flash graphics. Also before the webpage moves to the main page an Flv is streamed (90seconds log. It is not embedded it is streamed). I have about 260 frames of jpegs Already compressed to about 70k each for each image. how I can reduce my file size? also my time line is 2750 frames long. This is for a client and the client requested all the animation, so how can I make this work, currently my swf file is 14.6mb
View 4 RepliesI could really use some help here, I'm trying to reduce the size of my animation for obvious reasons, usually ends up about 4mbs, im exporting from swift 3d, about 200-250 frames depending on editing. When I import the animation into flash to work with my website the resulting file is too large I think :P I was told to export from swift in avi and then import to flash after converting. Thats definetly reduced the filesize, but when I import to flash cs5 I get an empty symbol even after export from flash, nothing shows in the symbol.Can anyone tell me if im doing this right, or another way to reduce the filesize.
View 1 RepliesI have a game were there are a lot of little guys moving around on the screen independently of each other and I have a function for zooming in and zooming out. I want the guys to look good when I zoom in but not lag when I zoom out and show a lot of them. What I'm thinking of doing is just making different levels of detail that it uses for the guys at different zoom distances.I don't know what makes vector graphics lag. Is it the number of shapes it has to redraw every time something moves? Or is it just determined by the number of objects on the screen at a time regardless of detail? I want to know if it would make a big difference in lag before I go redraw everything because it would be a big task and I don't want it to be for nothing.
View 1 RepliesI am making a websites with fairly large videos in the background.The site is extremely heavy for the cpu and I was wondering if any of you guys know a trick on how to make flv streaming less heavy.Here are all my specs :

codec : On2 VP6 encode alpha channel, framerate : same as source.
Using progressive download
Video plays in a flvplayback instance nested in a swf that is loaded and added to the stage by an other swf.
Embed in the html page with swfobject, wmode = opaque.
Movie playing at 31 fps.
I have a 3D animation that is rendered to bmp frames.I have inserted the animations into a Flash doc.After editing, my final Flash movie/file is 20MB.what are the best ways of reducing or compressing the file size down to a resonable "web-ready" level? Around 8MB or lower
View 2 RepliesI'm trying to scale my timebar according to the time. So the longer the time passed the timebar will reduce. It's kind of opposite from the preloader bar. But when I tried my loading bar is increasing towards the left. Is there a way I can make it look like the bar is reducing?
function countTime():void{
var startTime:int = getTimer();
// this is for the seconds
var seconds:int = Math.floor(startTime/1000);
// this is for the minutes ...
var minutes:int = Math.floor(seconds/60);
seconds -= minutes*60;
time_mc.scaleX= -second
trace(minutes +":"+seconds);
