ActionScript 3.0 :: Movie Clip Instance Life Cycle During Class Between?
Nov 2, 2010
Nice to be back to this forum again. I need to know if instances of the movieclip, that is "classically tweened" are reused between keyframes, or are they recreated (reinstantiated). Thus may I rely on the fact, that only the properties of one single instance change during the classic tween, or are new instances created on entering keyframes?
My little experiments on that show that the bad variant is happening (instances are recreated), but maybe I misunderstand or misuse something? here is the link to the file which made me doubt (CS4). In the last frame of the animation all previously saved references to the instance are saved abnd compared in pairs. Not all of them are equal and sometimes event some are null.[URL]...
I am confused with how component life cycle goes when component build in MXML. and if MXML calls methods automatically then how to call any method in life cycle explicitly.
In UI component life cycle, I heard validation and invalidation events. Please explain me about these events in short. What does updateDisplayList() method do in that life cycle. Please explain me in short if possible.
Driven on by curiosity, I'm trying to understand the Life Cycle used by Flex Application. I've done a little research on this argument; the two key concepts used into the FlashPlayer are:
SWF Frame: it's the logical unit that contains graphical code and as code Flash Player Frame: it's the time interval used by Flash runtime to update the screen and defined by frameRate property
If so, could you explain me the relationship bewteen these two concepts? In particular, are they paired togheter or not? The main rule is: the Flash Player streams in a swf; until a full SWF Frame is read, the Flash Player cannot render it.
I'll try to explain what I need to understand. For the sake of simplicity, suppose you have a two frame application: SWF FR 1 and SWF FR 2.
In general (for example in CS4) a frame is considered as a logical unit (delimited by ShowFrame tag) where you can attach as3 code. This as a simplified version of a swf file, i think:
Header // frameRate is defined here Symbols, classes etc... // this is FR1 === ShowFrame === Symbols, classes etc... // this is FR2
If you have two frame, FR1 and FR2, Flash starts executing FR1 and goes to the next one (FR2). If you don't stop the excution, the Player executes and renderes code contained into FR1 and FR2 through an infinite loop. On the contrary, when you stop the execution, for example in FR2, the flash player loops executing code contained in FR2.
that said, i have a simple movie clip animating that i want the user to be able to click different buttons to cycle through different versions of this movie clip. so, my question is, how do i allow the user to click one of these 4 buttons, and have the movie clip change to the corresponding version of that movie clip? again, this is all pretty basic stuff and i'd like to keep it as simple as possible, since i'm still new!
I placed a movie clip instance inside a button, and I want this movie clip to play when the button is released. I'm using this code on the frame containing the button:
function playMovie(event:MouseEvent) { this.theButton.theMC.gotoAndPlay(3);
In my project are pages of text with each word having a button that when pressed will display a movieclip presentation about that word (its pronounciation and spelling etc..). In the project I am working on now I have over 450 unique presentations of words to deal with. I don't want to have all of these hundreds of movie clips on the stage and tell them one at a time to stop and rewind and then have one play each time a word button is pressed. That seems to be very inefficient to me.
add movieclips to the stage using addChild(movieclipname) and remove them using removeChild(movieclipname) but there is a problem. I have hundreds of unique movieclips and I don't want to have to manage hundreds of variables containing the indivudual movieclip instancess. It is a real pain having to figure out what instance is still on the stage before i delete it.In Adobe Director all I have to do is this:
I have a label I am referencing form a movie clip inside the movie clip which contains the "label_2." Here is the code I used: MovieClip(parent.parent).gotoAndPlay("return_2"); Now I need to reference a instance name of a movie clip in side the same scene.
i created a bouncing ball effects with as2 .it shows 8 ball bouncing each other and moving. now i need is when i click on each ball it should display ball1, ball2, ball3 ..etc to a text box. when i put this code
how to get rid of an instance of a movie clip in the following Scenario. I have tried several methods, e.g., setProperty _visible to false, and the setProperty _scale to 0 (below). But none of these methods really get rid of instance; it merely hides them.
if (_root.yellow, hitTest(_root.wall)) { speedx = 0; speedy = 0;
I have a base class which is being created via remote_object [RemoteClass alias] from the server.I have other specialized classes that are derived from this baseclass, but serialization with the server always happens with the base class.The base class has meta data that defines what the derived class is, for example
[RemoteClass (alias="com.myco...')] public Class Base {
I know reverse movie clips have been discussed a million times before but I gues I'm jsut stupid and can't figure it out. I have an instance of a movie clip on my timeline that I want to play on mouseover and start going in reverse on mouse out. How do I do it?
is there a way to set the depth of a movie clip instance that is on the stage, ie. not created via createEmptyMovieClip, attachMovie, duplicateMovieClip and so on? Something like
I want to load an instance into a empty movie clip on my scene1. On scene1 I have an empty movie clip empty_mc. In my library I have a jpeg I converted into a symbol. I through the symbol onto stage1 and gave it an instance name of jpeg_1. I want the empty Movie clip to load jpeg_1. I thought it was something like this.
I have an issue while trying to create an instance of a movie clip, in order to rotate it dynamically. How can I have a variable of type myMovieClip in which I can invoke the _rotate method?
How do I access an object (in this case a button) within an instance of a movie clip on the stage?Basically I want to listen for a button (but_1) within the movie clip instance (menu_bar_1) which is set on the stage of my main movie.I want to use that same movie clip in several different parts of the main file, and each time the button will play a different sound.
I thought this would be a simple one, but i am stumped. So I resulted to using this less than optimal solution, just to get it working...
if (lobby.gamemap.selectedItem.label == "Map1") map.AddMap(new Map1) else if (lobby.gamemap.selectedItem.label == "Map2") map.AddMap(new Map2) //Map1 and Map2 are movie clips in my fla library, with linkage Map1 and Map2
ActionScript Code: myVar.addEventListener(MouseEvent.MOUSE_OVER, dothis); function dothis(event:MouseEvent):void { myVar.gotoAndPlay("rollover"); }
I have a hundred instance of a movie clip on the stage. I would like to use "myVar" to store the name of the instance that the mouse is currently hovering over, so the function will run for that instance.
how to dynamically assign the instance name to myVar on MOUSE_OVER?
I need to make movieclip carbondot and its actions automatically duplicate into a new instance after being dragged, but my current coding for carbondot isn't working:
I'm trying to get a button that I made, which is in a different movie clip, to change the video in the video list.[code]The button instance name is "v1btn" and it's in the movieclip instance name "menuBtn"
I've got a map, of those you roll over the mouse on the sections and it displays the section name.I want to add to these code, the instance of changing the colour of the section, so sections are more visible each time you move your mouse over the map.[code]...
I have four movie clip instances inside an instance. ("root" or "stage" > mcInstance1 > mcInstance2)
I have my actionscript codes enterd on the first frame of the mainTimeline.but my knowledge on actionscript 3 is so short I couldn't control the mainTimeline from the instances which I have created as buttons by actionscript coding.Here's what I'd like to do: When one of the movieclip instance is clicked and onEnterFrame,I want another movie clip instace to play which is on the mainTimeline (or "root" or "stage") on top of everything.I even tried to loadMovie and addChild to the stage onEnterFrame of the movieclip instance, but since it does the loadMovie inside instance stage, it appears only on top of the same movie clip instace and not on top of everything else.how to control a movie clip instance on mainTimeline inside the movie clip instance onEnterFrame in AS3.
Building a dynamic map that displays State Senate districts for a US State. Each district is a movie clip that I want to manipulate from a ColorTransform perspective on the flash map. The data that drives the map is being pulled from a php/mysql script. I have built out the actionscript up to the point of being able to trace the name and desired highlight color of the Senate district passed from the php (the passed name corresponds to the movie clip instance name of the district on the flash map). The traces work fine as far as the values of the data passed, one field is the district and the other is the color for the transform. The .as file compiles on the test, but will not treat the variable name used for the passed district as anything other than a String. I get an Error #1069: Property transform not found on String... Have gone through adobe reference pages and have tried every method of type conversion I could find to no avail. I get coerce errors on most attempts to force the String to be an Object.
I've started to Flash again after a long time. I'm excited. Whatever, my problem is simple. I want to reach a instance name from a movie clip. For example, I made a movie clip that has 2 frames. Name of the second frame is "secFrame". There's a movie clip inside the frame(i'm talking about the frame that named as "secFrame") that has a instance name as "mcSecFrame". Also the instance name of the main movie clip is mcMain. Now, the problem is, how I can control the mcSecFrame instance name with the code that is written on the mainTimeline's frame? For example, I want to control its frame rate. I wrotethis:mcMain.secFrame.mcSecFrame.frameRate = 5;But it doesn't work.
I'm using a library that has a function that returns an instance of some class Engine.
I'd like to tack on some interfaces to Engine, so I subclass it class InterfacedEngine extends Engine implements AwesomeInterface. but when I change the code that uses the classes from this:
var engine:Engine = generateEngine();
to this: var interfacedEngine:InterfacedEngine = generateEngine();
It gives me a runtime error (elision mine):
TypeError: Error #1034: Type Coercion failed: cannot convert ...::Engine@1bc2bf11 to ....InterfacedEngine.
I have to admit I pretty much ran away from Flash when AS2 came along and only used it for animation purposes over the last 5 years.So I'm having a major crash course in AS3 in Flash CS3 and I'm not enjoying it one bit. I'm getting maybe 10mins of finished work per hour as I try to figure out the limits and rules of AS3. Quite often it seems that AS3 simply can't do what I want it to. Anyway: Characterchecks.as is the main class and it loads a bunch of XML into four arrays. The file starts like this:[code]If I trace the value of, say, cc._Categories from the main FLA, it's empty. I'm guessing that the next line of AS in the main FLA doesn't wait for the previously called function to complete? (This may tie in to my next problem)My next step is that I want to display various things based on the data in the array. I have another class, Display.as which will hold all the functions to create the items on display. I thought it would be best for these to be a separate object. I wonder if I'm right?
So I declare an instance of Characterchecks in the main FLA and call it cc, and then run the functions to populate the arrays... Now I create an instance of Display and call it cd. How can I get functions in cd to see the values of the variables in cc? And if the main timeline can't tell that the functions aren't finished filling the arrays, how is cd supposed to know?I might be asking dumb questions, or maybe I'm doing things ***-backwards, I don't know. I'd appreciate any help, I really would. This whole thing has me at the end of my tether... being the most technically advanced person in my circle of co-workers and web design friends means I have no-one to explain why things need to be done a certain way or what the best way is.
