Not having a movie clip on the stage until needed (attachMovie when it's time, and then kill it as soon as it's temporarily of no use).visible = false^ Is there a difference in processor demand? When setting visible to false, it seems to me that a few extra variables would need to be stored for the movie clip..._x, _y, _width, _height, _alpha, etc., etc., etc...but I wasn't sure how Flash goes about handling these things or which was better practice?
View 9 RepliesI am just wondering what the differences between these two are. I have an animation that I am trying to make as optimized as possible to get the best possible frame rate. I have clips on the stage that start out visible, but are then set to _visible = false for the remainder of the animation. Basically I am just wondering, is a clip still using cpu power if it is set to invisible? Would it be more optimized to swapdepth the clip to a removable depth, then remove it from the stage with AS?
View 2 RepliesI followed Kirupa's custom scroll bar tutorial and I'm trying to tweak a few things. Where would I put the code to make the arrows invisible when the content can't be scrolled any higher or lower? This is different from the scrollFace being invisible. I don't mean when there is no scrolling at all. Also, where would the "return to visible" (else) code go? The code I plan on using is:
btnDown._visible = false;
else btnDown._visible = true;
btnUp._visible = false;
else btnUp._visible = true;
how the _visible property works and how I can use it with loading external movies into my main.swf...I have 3 movies loading into my main and I want to hide two of the movies until my main movie is preloaded. I am using a preloader for the main movie but I don't need it for the other two movies...
View 1 RepliesLong time listener, first time caller here. I'm having trouble with how Flash sets the _x property of a dynamically created movieclip. If I create a rectangle on the stage using the Drawing API:
Code:
//for the purposes of this example, assign a value to i
var i:Number = 0;
//assign var squareName
var squareName:String = "square" + i;
//create an empty movieclip named [squareName] at depth 1
this.createEmptyMovieClip([squareName], 1);

I'm not new to Flash by any stretch of the imagination, but I have never come up against this problem before. For context, I'm actually getting my feet wet with the Tween class, and am having trouble animating dynamically created movieclips due to this confusion with coordinates. When I tween a dynamically created clip from one set of coordinates to another, they are offset by the movieclip's _x and _y properties starting at 0, 0, rather than their actual position on stage.
Are you aware how to set a variable to true or false in AS3;

I have 2 EXTERNAL movies being loaded with initial load of my site into my main.swf, one of which (movingbg.swf) is being loaded with a preloader.

I have some AS that creates a movie clip and later tries to make it go away. However, _visible isn't working as I would think. Here's a sample: I create the triangle:
[Code]...
It doesn't work, however. So, I tried trace(triangle30._visible) both before and after the second chunk of code, and it does indeed change from true to false. However, the movie clip is still visible on the screen.
Here 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.
How do you make the childAllowsParent property of an SwfLoader go from false to true, that is, how as a parent application do you set up security to make the child app's events and other properties accessible to you. To read the flex docs on this, one would think nothing could be simpler:
"This property [childAllowsParent] is set to true if the child object has called the allowDomain() method to grant permission to the parent domain or if a URL policy is loaded at the child domain that grants permission to the parent domain. If child and parent are in the same domain, this property is set to true . [emphasis added]" So, I'm in a development environment and want to load an swf from my own system via an SWFLoader and then be able to monitor its events within the parent app.

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 trying to create these 17 textfields in a for loop. I ended up instanciating them manually and now I am trying to set some of their properties in a for loop. The problem is that when I trace them I just see [object textfield] but not the names. If I try to trace the ".name" I get instance 1, instance 2, etc. The real problem is when I try to set the "y" property I get an error "1010 A term is undefined and has no properties"

This marks a new chapter for me asking a question about an entirely different subject that I know nothing about I'm following a book called "Flash Games" and it's not for beginners and I'm a beginner so lots of jargon that I don't know and simple google searches don't come up with anything. What is the Flash IDE? Does this author mean the application Adobe Flash to build applications. So that means there is Flex, and Flash Catalyst, and Air IDEs? I don't really treat this like IDEs in terms of programmer but I guess I just don't know. The author says to set the document property on my file.fla to Game. How to do this?

View 4 RepliesI'm trying to convert an MXML component to an ActionScript Class. The component consists of a Form with a TextInput, TextArea, and two buttons - Save and Cancel, and a Validator for the TextInput, and other logic to handle events that occur. This component is currently extended by several other components. Now, in the MXML component binding the TextInput text property to a property in an Object was very easy:
<mx:TextInput text="{_itemToEdit.name}" />
But in ActionScript, I'm creating the TextInput and setting the text property before the Object is set, and the TextInput is not being updated:
public var itemToEdit:Object = {};
private var nameInput:TextInput = new TextInput();
public function MyClass() {
nameInput.text = itemToEdit.name;
}
How can I make sure that the TextInput text property is bound to the specified property in the Object?
I'm looping through a recordset, and for each item I create at runtime a spark Label and set the text property from a field of the recordset. The labels must have a fixed width and some text goes multiline.

how to get the label height?
Short version:Setting a TextField's 'text' property seems to be quite slow. Any way to optimize this?Long version:For a video player I'm working on, I've rewriting a bunch of code I've written in the past and optimizing where I can, and I've noticed something a bit strange.I have a time readout (the typical "00:00 / 01:00" thing) that I'm updating every frame, and it seems to be gobbling up FPS (I'm using mrdoob's great little Stats class for monitoring).The thread to make the call is a bit heavy -- involving a dispatched custom event from the FLVPlayer class (with the current netStream.time as a property) onEnterFrame, which is passed up 2 parents and then back down via a function call -- but I've isolated each step along the way and everything is totally fine (running at or close to 30fps) right up until that very last call where I set the TextField.text property, which results in about a 10fps drop.
If I comment out the setting of TextField.text it runs great, but even if I set it to something arbitrary (like currentTime.text = "0") -- bypassing the reformatting math -- it just tanks.Anyway, anyone know if there's something I can do about this? I've considered using a Timer set to 100m instead of onEnterFrame, but I actually assumed the overhead would come from the dispatching of and listening to the event as well as the reformatting of the time, but *not* the very last step of setting the .text property, which is something I can't avoid whether I use a Timer or onEnterFrame.
I am using the combocheck example from the following site: [URL]
It's a very useful component and works very well.
Now, I need to set the text property of this combo box upon application startup with certain values (which are defined dynamically according to some criteria). The problem is that although I have no problem setting the text property of the combo box at other times of the application run, setting the property at startup seems to have no effect unfortunately.
For example, I want to set the text property of the combobox to "Bob" (which is one of the items in the dataprovider for the combobox) and the "set text" method is called on the combo box. Performing a step-through shows that the "set text" method is receiving the correct value item but not setting the _text property.
I have tried not doing anything until "ApplicationComplete" but no joy there either.
Here is the code (a combination of the code from the URL above and some other changes to it). However, as I've stated above, the codes does work. The problem is that it doesn't work at the application startup. Whenever an event is fired and setComboText is called as a result, the text of the combo box is set correctly.
private function onComboChecked(event:ComboCheckEvent):void {
var obj:Object=event.obj;
var index:int=selectedItems.getItemIndex(obj);

i'm creating a completely dynamic form. i want to assign a variable name to a textfield and then pass that variable with a LoadVars() object.
here's a small piece of code i can't get working:
//create movieclip (used like a form)
_root.createEmptyMovieClip( 'dialog_body', 0 );
//create textfield input

bottomline: if i create a textfield using the traditional method and assign the 'var' it works fine. if i create a textfield dynamically at run time, and use the *.variable property, the variable is NOT sent..
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.
does setting the fixed property of a Vector to true before entering a loop is better for performance?
