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 having a problem that I have not found a good solution for. I think this is a problem related to the Flash Player's architecture so an experienced eye here would be welcome.
Imagine you've got 3 symbols in the Library and create instances of them by dragging them onto the stage. Each object is linked to a class. Let's say the object classes are named ObjectA, ObjectB, ObjectC. Their stage instance names are objectA, objectB and objectC.
The classes of these objects reference stage instances. For example, ObjectA might have a reference to ObjectC, like this:
var _objectC = MovieClip(root).objectC;
ObjectC might have a reference to ObjectA, like this:
var _objectA = MovieClip(root).objectA;
It sounds like this should work but it doesn't. When the SWF is published, objects on the stage are instantiated in the order that they were dragged from the Library. This means if objectA is instantiated before objectC, it's reference to objectC will return null and the code will fail.
I know there are ways around this, but I'm trying to come up with a solution that doesn't involve the document class, a helper class like a singleton, or instatiating objects with addChild().
It seems that the only way you can be absolutely certain that all the objects have been instantiated is on the first frame of the movie. So I've been using a system that adds an enterFrame event listener to just get references of stage objects when the first frame runs, like this:
function findStageInstances(event:Event):void
{
var _objectA = MovieClip(root).objectA;
var _objectB = MovieClip(root).objectB;
[code]....
(Note: The ADDED_TO_STAGE event won't help in this case because objects are added to the stage by the SWF based on the order they were dragged onto the stage from the Library.)
I'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?
- I put 3 dynamic text field to stage. I selected Verdana both of them and select bold and italic for other 2 field. after that I created a textfield.
.embedFonts = true;
assigned "Verdana" font as TextFormat.
and when I assigned a htmlText to my field like that :"<b>this is bold</b> this is normal". I use Flash CS4, AS3
I decided to try to use setInterval for myanimation, which is just a mouse trail.However, I'm trying to get teh mouse trail to be a dynamic mask.In my previous swf this was achieved by using a holder mc with the animation inside and then using this as the mask. But this time I just canpt seem to hit on the right way to get it to work. The code I am using for the mouse trail is:
Code:
var i:Number = 0;
var myInt:Number;
var t:MovieClip;[code].....
in the function, but now the trail doesn't resize and the mask still doesn't work.
I have 2 input textfields on the stage and 1 dynamic textfield.
-input1 is for quantity
-input2 is for page count
When a user enters a number into the page count it makes a calculation and places the outcome into the dynamic textfield. This textfield is for the individual price.All of this so far works. What I want to do now is create another dynamic textfield for the total. So the individual price is multiplied by the quantity and this result is put in the new dynamic text field. I have the code for that working but here is where it gets tricky (for me anyway).The total price is to start off invisible. When I roll over the individual price the total price is to appear (For a test lets just say when I roll over an area the total price appears).To stop cursor flickering this should be done inside a movieclip. So... I have create a movieclip and placed a dynamic textfield inside it. They all have instance names BUT how do I reference it in script?I need to tell the resulting calculation to be placed inside the textfield which is inside the movieclip. If it isn't inside a movie clip I can do it. But how to I reference it when inside one?
I 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

View 1 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]...

I have about 100 movieclips that scroll across the stage from out of bounds. They are supposed to hit another movieclip both in bounds and out of bounds, but it seems like Flash only detects the hittest when it happens within the frame.
if(_root.sceneclip.reef1.hitTest(this._x+300, this._y+350, true) ){
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 Replieshow can i get any classname from a string without instantiation ? [code]
View 1 RepliesOk so when I test the file in Flash it appears totally fine and works...as an swf on it's own, it also works just fine. (I have a text box, mask, scrollbar etc etc). Text is loaded externally and seems to be happy and error free...
When I test the swf on a html web page, i can see the scrollbar and arrows etc, but none of my text appears. I've tried embedding the font characters but that doesn't help either.
I'm trying to make text disappear and appear letter by letter, so i'm using dynamic text. I've made this code which should do this, the only problem is that the text won't show up. I used trace to check what does the dynamic text box contains after the code has done it's job and it contains what it should. So I don't really understand where the problem is. I've embeded all the lowercase letters since I'm only using those... I don't know what else to add here... except the code offcourse:
Code:
if (_root.butonselectat<>"")
{
stop();
[Code]....
Ignore all the "ifs" they just make the code do it's job when it should. And it seems that they work correctly. The first "for" cycle removes the text letter by letter and it only works if there is some text in the dynamic textbox while the second "for" adds the text letter by letter. I have the same code on two keyframes in the first layer and the the dynamic textbox on the second layer with only one keyframe.
how to make my package use stage.stageHeight so I can tell a ball to bounce when it reaches the bottom of the stage. I'm calling my ball to the stage from the library in a way I'm not used to and have never done so I'm assuming it has got to do with that. if you take a moment to look at it (pretty simple i've stripped out everything except for the physics that makes a ball drop and bounce) and let me know why I cant detect the stage.

I have a project in mind in which I would like 3 sets of interlinked images that are displayed on the same stage. While the mouse is over one set the wheel button allows for scrolling through that set of images and so on for the other two sets of images.
How do I separate the three sets of images, so that scrolling through one set doesn't affect the other sets on the stage? Each set has about 30 images each.
I have a typical logo on the right top corner and a menu bar just above it. Above the menu bar, I have a UIloader in which I load photoalbum.swf when one of the menu buttons is pressed. The problem is that setting the scaleContent property to true doesn't load my external swf.Setting it to false, everything appears as expected, except that the bottom part of my photo album is cut since the scaleContent property set to false (this makes the loaded swf file's size the same as the stage's and as the UIloader begins just above the menu, the bottom part gets cut off).
View 2 RepliesI have tried everything I can think of but I just can't get my mask to move with my content when my stage is resized.
I am using flex and I embed symbols/assets in an assets class then instantiate them in my main class and call addChild on them.
I have a Sprite (maskSprite) that is the same size as the content, and I use this as a mask, calling
Code:
this.mask = maskSprite in my main.
This works fine but when I resize the swf it stays at the top left of the window when my content moves (I am using stage.scaleMode = StageScaleMode.NO_SCALE). I have used maskSprite as a non-mask and it moves with the content fine, but when it is a mask it doesn't.
I 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.
