Actionscript 3 :: Clone An Instance Of A Class (Display Object)
Jun 3, 2011
I have a collection of movieclips, I would like to create a clone (a new instance) of a instance everytime I create a new object.
For example
var s:Star = new Star(); // star-shaped movielcip
addChild(s);
// then I want to duplicate an instance of s and add it beside s
For an example like above, it's simple enough to create a new instance with a different name and just add it to the display list. But I have a list of objects I would like to clone as a group...?
I've created a class that utilizes setInterval...I call it in a different class...and I can't get it to make the setInterval call. I'm thinking there's a scope problem but I don't see it.
Class w/ setInterval:
Code: class Foo { private var id:Number; public function Foo() {[code]....
The function will get called but I need access to the class's instance variables inside display().
Is it possible to get dynamically created children of a display object instance in action script 3? Example trace(_view.getChildByName("name")) = returns name of display object (success) trace(_view.getChildByName("name").getChildByName("name2") = returns error 1061
I have the Dynamic Text field that has an instance name on a mid-timeline frame in Flash CS4. I have a class that inherits from Sprite, and which is always added to the stage on instantiation. How can I get a reference to my Dynamic Text instance from this class?
Example: My Main class (linked in Flash's publish settings) goes like this: protected function beginGame(e:MouseEvent){ gotoAndStop(8); var game:GameContainer = new GameContainer(41,8); addChild(game); game.x=36; game.y=128; }
Game Container extends MovieClip, and draws some pretty gfx. On Frame 8, in the Flash IDE, there is a Dynamic Text element instance named "scoreText". I want to access this from the GameContainer class. Possible?
Using Flash CS5 Professional I have created a symbol, dragged it onto the stage, and given it an instance name of GreenLight1. If I want to make this visible from the document class, I can simply do the GreenLight1.visible=true; and poof it's good to go when I test the file. As long as I stay in the document class I am good to go, but now I'm trying to move to another class and hitting ALL kinds of trouble just trying to get Flash to allow me to access this simple object. All I am looking to do is have this GreenLight1 go invisible (visible=false) when a certain condition occurs in this new class and Flash just won't let me access GreenLight1 at all. Things I've tried thus far:
stage is passed to the class and is referenced by _stage and is working just fine when I do _stage.addchild or anything like that. So I have tried "_stage.GreenLight1.visible=false;" and I get "ReferenceError: Error #1069: Property GreenLight1 not found on flash.display.Stage and there is no default value." My document class extends Sprite, so I figured I'd try the root function. So I tried "Sprite(root).GreenLight1.visible=false;" and I get "1119: Access of possibly undefined property GreenLight1 through a reference with static type flash.display:Sprite." I tried to create the Resource class as described therein. To which I came across the same problem that I started with in that it doesn't know what GreenLight1 is to begin with so I got "1120: Access of undefined property GreenLight1." Here is my code for Resource.as (am I supposed to pass something to this class from the document class?)
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]...
If I pass a MovieClip through as an argument in the constructor for a class I am writing, how do I create a new instance of that MovieClip from within the class?
The MovieClip has a custom class name that is unknown to the class I am writing, it is simply passed through as a MovieClip.
I tried:
Code: _class = Object(mc).constructor; _mcArray[i] = new _class;
How can I instantiate another class object from a class instance? In the code below (which doesn't work) I'd like the function to return a new class instance based the passed argument's class. In other words, I want the function to return a new instance of MySprite without having to call new MySprite();.
var mySprite:Sprite = new MySprite(); var anotherSprite:Sprite = makeAnotherSprite(mySprite); function makeAnotherSprite(instance:Sprite):Sprite { return new getDefinitionByName(getQualifiedClassName(instance)); }
I am trying to get the index of an object which is an instance of a class. I need to get the index from within the class.So I have an instance of a class. When its clicked I need to get the index. I dont really know how to write this. I tried a few things like:[code]
I need to be able to clone an object. The object is not a visual one, only having basic information (strings, booleans and integers). What I want to do is be able to get another object that is identical with the current one. Let me be more specific. I have the class RAM that has some info (like capacity and stuff like that). I have different object with different specs. let's call them ram1, ram2 and ram3.
I want a function that given an object will return another object with the same specs. I can always implement a clone() method inside the RAM class...but this isn't something portable and it won't work with other objects, for example CPUs. Is there any way I can clone an object. I already tried this: [URL] but that returns null.
If an object, or say... a document class, creates an instance of a class (and stores it as a variable), and it doesn't pass any arguments to the constructor of the class, can that class object, by simply having a function of it called by the parent, tell who sent it that command/request?In other words, can a class object know who called it (such as it's parent) via a (seemingly) anonymous call?
I have created some (TextInput, ComboBox, CheckBox) Component instances (created as a public objects) in a Document class and added them to the stage.
Now I have created a custom class for a movieclip in library and instantiated it in the document class (also a public instance).
I need to access the component instances in the custom class. How to do this ?
Also, Is it a good practice to use ENTER_FRAME event frequently ? because if I can't access the above components instances in the custom class then I will be left with no choice but to use ENTER_FRAME event in the document class every time I need to change some value in the components...
Im building a shooter game where a bullet is call from a class and the enemy is also called from a class.I cant make them collide. In order for stuff to start exploding.I have already tried two collision detectorsI keep getting this error
Code: 1120:Access of undefined property nBullet Code:
I can't work out how to create a temporary copy of a 3D point class on which I'll perform some calculations which I don't want to effect the original. In C++ it's called deep copying. How do you do it in actionscript?
(I see this same type of question was posted almost three years ago with no resolution, does anyone have a solution now? am trying to save a clone of a custom object (contains arrays and other custom objects as properties) to a Shared Object.Basically I have a menu system that created this program, it's running and at any point I want the user to be able to save it so he can go back to that exact point at a later date. Here is what I do so far:1. Pause the program2. The menu saves the variable that references the running program using a bytearray to a shared object3. A a later time, to load the program I pull the data from the shared object and save it to a variable, which I then treat like the original programHere is my code to save the data:
Code: var byteArrayCloner:ByteArray = new ByteArray(); byteArrayCloner.writeObject(myProgram);
I have this "left half of a door" image in my library, and I did cloned the same image to the stage, making it "right half of a door" but really would like to know what would be the right way of doing such things..[code]Should I just make new instance, or do it through function? Is there a memory issues in one of those, what hurts Flash more?
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 {
Does creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
I am using Flex 4 and for whatever reason I cannot get the following code to work which happens inside of a ListEvent handler for a dataGrid: _tempRule = DataGrid(event.currentTarget).selectedItem as Rule;
Rule is a custom class, and the above code always returns null. The dataprovider for the datagrid is an ArrayCollection. If I try to wrap the above code to make it like the following: DataGrid(event.currentTarget).selectedItem as Rule
I get this error: TypeError: Error #1034: Type Coercion failed: cannot convert Object@e15a971 to com.mycompany.arcc.business.Rule
Now I know I have done this before with native Flex classes like Button, etc, but it my case it will not work. Here is the Rule class: package com.mycompaany.arcc.business { import flash.utils.describeType; import mx.collections.ArrayCollection; [Code] .....
If an object, or say... a document class, creates an instance of a class (and stores it as a variable), and it doesn't pass any arguments to the constructor of the class, can that class object, by simply having a function of it called by the parent, tell who sent it that command/request? In other words, can a class object know who called it (such as it's parent) via a (seemingly) anonymous call?
I want to load some .swf files using the Loader class. I'm all set with that and got the image on screen but I wish to have multiple instances of it. Do I have to reload one for each that I intent on using?
For example say I'm attempting to load a power up's graphic from an .swf (i'll call it ex.swf). I load it and then put the image I loaded into the power up. But then I also want to have another power up of the same type somewhere else, and I want to use that same graphic. Neither adding the loaded ex.swf's contents or simply assigning the contents to a child of the power up will work obviously. So do I have to load a new copy every single time i want a new one, or can I just clone/duplicate the contents?
I mean I know it must be common for games to have 100's of copies of the same graphic being used by different things, yet If I try to preload the amount I'd need it's not exactly flexibly and if I load them as I need them it seems bad practice..
I am programming a web based application with Actionscript 2.0 classes for flash 8, and I want to save user data using the local shared object.As the data is potentially rather complex I would prefer to store it in an instance of a custom class that I then stick in an array property of the local shared object data property.However, when I try to do this, if I retrieve the stored object it seems to have lost all its instance methods. If I do a for in on it, I can see the private properties to which I have assigned my data, but as they are private I cannot retrieve them.how I can store an instance of a custom class in a local shared object without it being corrupted in this way?
//The test_close is an instance name which I drew on the canvas. var cloneMe:MovieClip = new MovieClip(); cloneMe.graphics.copyFrom(test_clone.graphics); //here is my clone codes addChild(cloneMe); trace(cloneMe.getBounds(cloneMe));
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.
