Actionscript 3 :: Pass Arguments To Stage Instances
Sep 26, 2010
I have an instance on my stage that I dragged from my library at design time.This instance links to a custom class who's constructor takes an argument.[code]Is there any way to set arguments on an instance that has been manually dragged to the stage?
Is it possible to pass constructor arguments to instance objects which I place on the stage? Are the instantiations of instance objects centralized somewhere as with .NET WinForms so I can just edit the xxx = new CustomRecangle() constructor?
public class CustomRectangle extends MovieClip { public function CustomRectangle(width:int, height:int) { this.width = width; this.height = height; } }
In "my actionscript theory", I'm supposed to see a circle that follows the mouse when I click it. (The draggable is not fully implemented) But the circle doesn't even budge .how to access the main class's stage property. I've googled for it, but still no progress.
I am teaching myself AS3 and using FlashDevelop for all of my work (so far so good) and I have hit a snag with passing arguments.What is the best way to pass arguments of one array to another? Ie, I want the Harvester class to have visibility to the Resource class so I can do some iteration.
I have been given the requirments to modify a website intro. Basically it has names fly in and out one at a time. Each name that flys in has some text effect on it. They had each name set up as it's own movie clip.
I want to make this more dynamic by putting the list of names into an XML file. Then after reading the XML file, pass each name one at a time into a movie clip. I thought I could set up several different movie clips for the different text effect and then randomly choose one.
I know how to read the XML file, but that's about it.
I need to know how to pass info into a movie clip. I need to know how to call random movie clips. And it would be nice to know how to make it loop through the names and have the effect appear on screen.
I am creating the columns of a datagrid dynamically at run time and I need to allocate the sort compare function to those columns based on the data type of that column, is there a way I can pass some argument to that compare function which could tell the function what type of column is it going to operate on?
I have searched the web for a satisfactory answer and have not got one yet.
Below is a function that has an argument passed to it that I would like to pass on to an event Listener. The listener should pass the variable on to another function. Looking at the structure of listeners this is not acheivable[code]...
I'm passing a DisplayObject to a command that will instantiate it. Something like this:
// ViewClass is passed into this method typed as a Class var view : DisplayObject = new ViewClass() as DisplayObject;
Is there a way to pass arguments to ViewClass() without knowing it's type? I'm assuming the list of parameters passed to any object's constructor is an array, but I'm not certain how to proceed.
I know I can do something like this:
// Assume arguments, an Array of arguments, has also been passed in var view : DisplayObject = new ViewClass(arguments[0], arguments[1], arguments[2], arguments[3], arguments[4]) as DisplayObject;
But clearly I'd like something more dynamic, like to be able to just pass the arguments Array directly. I suppose all of this, however, goes against any type safe checking
I searched the interweb for DAYS trying to find how to accomplish this via an event listener in AS3, but everything I found suggested creating a custom Event. The problem with this, is you have to decide the arguments you wish to pass in advance, and I wanted to create them dynamically on the fly ( for example: passing a string that a user entered into a textfield to some function for processing ).
So last night I spent hours scouring forums - and UREKA! I finally found something that I was able to tweak to send a variable number of arguments of any data type. I've never posted on a forum, but it was such a breakthru that I had to share it with the world.
Here is the code:
btn1.addEventListener( MouseEvent.CLICK, function onClick(e:Event ) { displayArgs(e, new Array("Larry", "Curly", "Moe") ) } ); btn2.addEventListener( MouseEvent.CLICK, function onClick(e:Event ) {
I want to pass through configuration arguments to a class. These are all the optional vars that go into configuring the class - and should be able to run in any order.
at the moment i just pass through the optional vars the regular way. Supposing the constuctor was like the following:
private var _reqVar:String; private var _optVar1:String; private var _optVar2:String;
[Code].....
assigning the argument to the var of the same key (i know in php to reference a variable name from a key you can use $$key = $value, is there an equivalent in as3?) display an error (using the 'throw' method) for variable names not supported by the class
var service:HTTPService = new HTTPService(); if (search.Location && search.Location.length > 0 && chkLocalSearch.selected) { service.url = 'http://ajax.googleapis.com/ajax/services/search/local'; service.request.q = search.Keyword;
[Code]......
I want to pass the search object to the result method (onServerResponse) but if I do it in a closure it gets passed by value. Is there anyway to do it by reference without searching through my array of search objects for the value returned in the result?
I have an object that has all the elements I would want to pass arguments: var args:Object = { 'dog', 11, myArray }; and I want to be able to pass the contents of args to doSomething without making any changes to doSomething (assume it's someone else's function) and I'd like to do it in a way that doesn't assume I will know anything about the contents of args.
Basically what I'm trying to create is a custom timer that uses frames rather than milliseconds. But I can't figure out how functions like setInterval calls the function you passed along with the arguments. First I create a reference to the function I want to execute after a certain interval and name it fc, then I create a list of arguments my function want to pass using Array, but then how do I put those arguments in fc()?
I need to be able to communicate between two applications that reside on the same machine. One is using Flex and the other is in C++. I would like to be able to call functions and pass arguments to each other. What is the best way to communicate between them?
Since when using sql lite if you try and do a function at the same moment it throws an error, im just trying to make a function that will check if its executing, and if it is try again in 10 milliseconds, this exact function works fine if i dont have to pass any arguments to the function but im confused how I can pass the vars back into the function it'll be executing.[code]
For example, I have the class Bullet, with a constructor: Bullet(start:Point, target:Point)constructor
But, if this Bullet class extends the MovieClip class, how do I pass start and target into it? Right now I am using attachMovie to create instances of the class. (They behave correctly with the static properties set by the constructor, but to be useful it needs arguments.)
How can I achieve the following for any number of elements in the arg array? If it was a function, I'd use Function.apply(), but I can't figure out how to do it with the new operator.
var arg:Array = [1,2]; new MyClass( arg[0], arg[1] );
I have this library with more than 80 objects that i want to bind to my keyboard. My idea is use the "keyCode" to call the object to the stage, constructing the object's name inside a variable.This is the code that I'm trying to use, but the bold text line always give me an error (constructor, syntax and others) depending how i write that line.[code]I'm not very experienced with AS3 so i don't know if this is the right approach to solve my problem. Any help is well received.
I am making a flashcard game with five subjects. It has buttons for moving forward and back,and buttons for switching to another subject The card instances for each subject are stored offstage, in separate frames (five in all), and their names are stored in arrays (five in all) Each time a button is pressed, the appropriate card tweens onto the stagepoint were still visible (not sure why, since the menu's on it's own frame), so I wrote a function to clear everything offstage whenever the menu button is clicked.My problem is weird: if you are in the math subject, switching to geography returns this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at flashcardapp1_fla::MainTimeline/frame3() at flash.display::MovieClip/gotoAndStop()
I'm new to this OOP stuff, and I'm having a hard time understanding all of this.I'm trying to recreate in AS3.0 with classes a simple whack-a-mole game I created in AS2.0 using timeline coding.I've read through a lot of forums, but I still don't understand what exactly I'm doing wrong.Heres my setup:I have a movie clip named mrBunny (my girlfriend told me to change it to bunnies as moles were too ugly.). Now there are 6 instances of mrBunny on the stage, each named mrBunny0-5.The mrBunny symbol is linked to the com.mrBunny class.The class has a method called randomPlay(); which I use to randomize the animation times of mrBunny.I also have a button on the stage with the class stageBtn.
I'm working with Flash Builder 4.6 as an IDE and Flash CS5.5 to create library items. The problem is - when I put an instance of a library item on the stage or inside of another item, Flash Builder fails to detect the instance name that was declared in Flash CS. This doesn't prevent the code from compiling just fine though.
I understand that the IDE only sees the fields that I have declared directly in the .as file, but it really hinders me that I the IDE goes crazy when I do this.
Is there any way to circumvent this - other than dynamically creating and placing the instances?
I was just wondering if there was a way to find all button/dynamic text instances that are on stage. This would allow the dynamic creation of array instead of having to manually create this array.
