View 1 RepliesWhat's the difference between Extends and Instantiation? It seems like they're both ways of getting content from a class.

View 1 Repliesi came across this problem and i have no clue why it's happening. basically, consider 2 nested movieclips on the stage, something like stage -> main -> filler. both movieclips have instance names (main and filler).
[Code].....
this throws an error 1119: Access of possibly undefined property filler through a reference with static type A. can anyone give me a hint on that, as it works with class A, but not B extending A? i understand it was meant to work?
I am trying to call a custom component but it keeps telling me this:

Having a bit of a problem creating an instance of an object. Bear in mind that this is timeline based and NOT an external class¦

Everything runs fine until the 'new_foo = new foo();' bit, at which point I get the #1007 error.
i am getting an error"TypeError: Error #1007: Instantiation attempted on a non-constructor" at: mybytes = ByteArray(new myClass());

it possible to create a button in flash that when clicked the flash interface extends to fit fullbrowser?
View 4 RepliesI created a movieclip symbol and exported to actionscript, I created the .as file:
class BRIQUE extends MovieClip
{
function BRIQUE()
{

"graphics" is an image imported on the stage inside my symbol, but it seems not to be accessible this way (I get an error), nevertheless it works this way in as3 then what is the right way in as2 ?
I'm encountering something a bit bizarre, but maybe someone else came across this before.
I've got a base class, that doesn't extend anything. Let's call it...
public class FooBar {
//...
}
But I want to bind EVERY single one of its exposed properties:

clarify the different logical instantiations of objects in actionscript?So far it seems there are 3 layers of instantiations, for lack of a better term.The first one is declaring a variable/type.Next is instantiating that variable with something solid in the code, like a method or function? Is this just a way to glue things together? Then after that you instantiate it on the stage, is this something you have to do explicitly, or is it a side effect? Is this "3 layer" concept the correct way of looking at it, kind of like the MVC for flash app logic?
View 2 RepliesWithin my flash file, some of the layers/objects go off of the sides of the document as I want them to. When I play the file within the test movie function within flash, the file plays fine and none of the layers that extend of the document cause problems(the samething happens when I play it in flash player). But when I open the file in a web broswer the layers that extended off the edges of the document show up. Is there anyway to get rid of this without having to redo the whole file? (ie, crop around the main document size, or set it to export only everything within the document and nothing that extends off of it?)
View 1 RepliesI am looking at the singleton design pattern and trying to really understand what is going on here. But I have some questions that it would seem my logic and/or the way I am reading this is wrong. Take the following code for example

I'm getting the following error:TypeError: Error #1007: Instantiation attempted on a non-constructor.at Website()[/Design/The Silver Collective/_classes/Website.as:42]
This is line 42:var top = new top();

Is it possible to have a string "ClassA" and use it in order to instantiate a real ClassA in my application?
View 4 RepliesI wrote a script to make a random image from an array appear and float up through the stage. The problem is that at some random time in the movie, i get the error: TypeError: Error #1007: Instantiation attempted on a non-constructor. at Untitled_fla::MainTimeline/enterFrame() This occurs at random intervals. From that point on, the script stops working. There must be something wrong with the way I generate MCs from the array.[Code]...
View 1 Repliesfirst it might be valuable to mention that i have a one document class and a child of that class, which is the one im having problems with. My library objects is added to the stage perfectly, but after i wrote the last code (in bold), i get:
TypeError: Error #1007: Instantiation attempted on a non-constructor.

I'm building an application where it would be sweet to use dynamic instantiation of Classes.I'm using "flash.utils.getDefinitionByName" to get this done and, if I instantiate the Class in my code once, there is no problem at all.But, I want to be able to do this without instantiating the Class at least once before I go with the getDefinitionByName method.I'm using Flash Develop and the Flex SDK, coding with pure AS3.Is there any way to instantiate the Classes only dynamically?Or, any alternative to the getDefinitionByName method?
View 7 RepliesI've been coding a bunch of movie clips as buttons (gives me more flexibility) and the lines of code is phenomenal... was wondering if i could create a template of functions, and instantiate it for each object?

unimatic.gotoAndPlay(2);

I am just trying to explore flash by my own little cognitive thinking..
import flash.events.Event;
var slot:Array = new Array(26);
var letters:Array = ['a','b','c','d','e','f','g','h','i','j','k','l','m ','n','o','p','q','r','s','t','u','v','w','x1','y1 ','z1',"hypen"];
var posx:Number = 125.5;
var posy:Number = -47;
[Code] .....
And the error is pointing in this line of codes:
this[getChildByName(letters[rand]+counter)] = new this["mc_"+(letters[rand])];
import flash.events.*;
var cloudInstance:Cloud = new Cloud;
this.cloudInstance.x = this.hero.x;
this.cloudInstance.y = this.hero.y;
[code]....
I instantiate my Cloud class that has that name from the library and exported for AS.I give it the x and y positions of another mc
I found two difference that I feel might be important:
-If I decide to put the variables within a constructor, then I must have an object parameter for any function that wish to alter the variables, even if the code is internal to the class.
-Subclassing would cause the variables to not appear, something that causes problems when the class and any subclasses must have the variables in order to operate properly.
I am instantiating the 'Target' object five times on the stage. This is happening, but only one object is able to have hitTestPoint performed on it. Can anyone help as to why this is happening?[code]
View 1 RepliesI've just migrated to AS3 and am trying to get my head around how to instantiate library symbols as instances of a class.Here's the problem: I'm making a tile-based game with a Map object to which are linked many Tile objects. Now while I initially create blank tiles, I later want to populate them with terrain. This operation will change thus the tile's _terrainType property. Finally, I want to then draw the map consisting of its many tiles. Tiles without a terrain type will remain plain vanilla, but those that have terrain types specified would obviously appear different.
Now the Tile object itself extends Sprite, so it is a DisplayObjectContainer (k, no problems there). My question is, how do I now either a) directly assign it a library symbol graphic,following it's instantiation (if this is even possible?) or b) dynamically use addChild() to add a library symbol graphic of a certain classname (my preferred tactic)? The problem is if I have to do something like this...
Code:
var tileImg:MovieClip = new mountainTerrain();
addChild(tileImg);
then I have to write a bleedin' huge switch() statement to reference a hash table which specifies which terrain type refers to which symbol class type, which is just ugly and crap.The most logical thing to me would seem to be something like this...
Code:
var tileImg:MovieClip = new eval(classname)();
addChild(tileImg);
...but clearly I'm misguided because eval() doesn't even exist in AS3 and I have attempted it's equivalent with no likelihood of success.How do I dynamically add a graphic to represent each instance of my Tile class?
how can i get any classname from a string without instantiation ? [code]
View 1 RepliesI have an image gallery with thumbnails and a previous button and next button. "nextPrevPosition:Number" starts out with the value of 0 and increases or decreases by 1 every-time the previous or next buttons are pressed. The thumbnails assign a value when those are pressed:
Quote:
private var nextPrevPosition:Number = 0;
private var currentPort:MovieClip;
private var POSITION:Array;
[Code].....
all works fine except when NextPrevPosition reaches the original value 0...and this is when I get the error message. It looks like the line "currentPort = new(POSITION[nextPrevPosition] as Class)(); is when it is happening.
After a couple of hours of looking into a weird 1007 error i give it up. I hope you guys can help me with the Error #1007: Instantiation attempted on a non-constructor error i have.The problem seems the creation of the laughing man icon instance.[URL]..
