ActionScript 3.0 :: Creating Copies Of A Dynamic Class?
Aug 13, 2009
I'm working on a particle emitter, and I want to be able to pass in custom sprites (one for smoke, one for fire, et cetera). They are instanced on in the library as separate classes, but I want to be able to call a function like, "ParticleEmitter.SetSprite(Smoke)", then have it start creating instances of the smoke class.
The problem is, I don't know how to pass in a class name as an argument or how to use it to create copies. Is there any way to do this, or would it be best if I just put all my different particles inside a MovieClip and set the frame for each one it created?

I have the following code
///Get BitmapData from library in SWC
var ClassReference:Class = getDefinitionByName(products[i].producticon+"Data") as Class;
// Create new BitmapData Instance From it
[Code]....
I get null in the trace. How do I make a dynamic class that I can refer to for this bitmap similar to how your reference a class from and embedded media?

Is there a way to generate an instance of a class that implements an interface based on the name of the class?
I am trying:
var ClassReference:Object = getDefinitionByName("movement.OuterSpaceMovement") as IMovement;
var m:IMovement = new ClassReference as IMovement;
trace("startup..." + m);
-But I am getting an error message ReferenceError: Error #1065 (OuterSpaceMovement) not defined.
I have several classes that implement the same interface (IMovement) but I need to be able to generate new instances of these classes and then pass these instances as a datatype (IMovement datatype) to other classes...
So then I tried:
var ClassReference:Class = getDefinitionByName("OuterSpaceMovement") as Class;
var m:IMovement = new ClassReference() as IMovement;
and this doesn't seem to work...but the following
var m:IMovement = new OuterSpaceMovement();

I'm trying to create a new instance of a MovieClip when the original one has been used. Would sound easy enough. Just use: var
instanceName:ClassName = new ClassName();
the class name/mc in the library im trying to duplicate is MCg1 so
var instanceName:MCg1 = new MCg1(); right?
However, the particular object in the library i'm trying to duplicate has a base class that is an external class file (just to control it's drag drop functionality)... i.e baseclass is not set to the standard flash.display.MovieClip, or whatever the case maybe. So i end out with a: TypeError: Error #1009: Cannot access a property or method of a null object reference.

I want to generate a mc for each rep with 6 text fields containg the 6 values for eash rep.So for this xml there would be 3 mc's with 6 text fields in each. This is one of my first times really diving in to xml parsing in Flash.

I'm creating a slideshow where each slide can have:- a video or a still- 1 audio track or many (up to 3)- 1 button or many (up to 3)I was thinking that each slide can be it's own object, and then I would pass the video, audio, buttons, etc., into it as parameters:

I have a class that represents a turret in the center of my screen.When I hold down SPACE, I want it to create a "bullet"-object that moves in the direction of the turrets cannon, every frame the SPACE key is held down. I am having problems with this cause I am getting this error when I am trying to create the object:
Error #1009: Cannot access a property or method of a null object reference.
This is where the error occurs:
ActionScript Code:
public function chaingun(x_:int, y_:int, rot:int, cd:Number, spd:Number, sprd:Number, life:Number) {
this.Cooldown = cd;
this.Speed = spd;
[code]....
PS: What happens is that when I press the SPACE key, the "turret" class event handler runs the function "Shoot_Chaingun" and that function creates a new Chaingun-object (which actually is a bullet), that inherits the x, y, and rotation of the turret, along with some additional varaibles, including lifetime. Then upon creation, I use "addChild(this)" to add it to the main stage, and "removeChild(this)" once it's lifetime is up.
EDIT: And also, I just realized I don't have a MovieClip linked to this chaingun class. How do I make sure that every time a chaingun object is made, the MovieClip is also loaded?

I've used the New Library panel to copy symbols from one Flash document to another & subsequently closed the extra Library panel. I did this twice for on different occasions.
My Library panel is usually docked & collapsed so ocassionally I use Crtl-L to expand it. Now, when I do that, the previous 2 extra Library panels also appear & I have 3 Library panels on the screen - 1 docked & 2 extra floating ones! How do I get rid of the other 2 for good?

I have a movieclip wich has a simple movement of a simple shape. This movieclip is copied many times to create a graphical effect. As the number of copies, or the complexity of the movieclip increases, CPU usage goes up. As from 90 copies, when I keep moving the mouse over the swf movie in a circle, playback stops (hangs). When the mouse movement stops, the swf continues again at the right position, as if calculation has continued, but updating the display has not. Now this is a quadcore pc, and we're 2010. I can't believe or accept that 100 mc's is the maximum number of movieclips that can be rendered. The obvious question is what can be done to optimize CPU performance ?
I'm using AS3, flash player 9.
Movieclip is a simple rectangle shape which moves along 1 axis.
var myLinkage:Class = Class(getDefinitionByName(getQualifiedClassName(McToRepeat)));
var newMC:MovieClip = new myLinkage();
containerMC.addChild( newMC );

I attained the print count but unfortunately I can't get the
no of copies during print. When the user increases the no of
copies i need increment the PrintCount.

I load images into my .xfl project and use them amond movie clips - everything is ok at beginning. But after a some moment (which is absolutely undefined) Flash Professional CS5 starts duplicating all of them at saving and new copies names with "Copy 1", "Copy 2" and so one, or just with blank string. Because Flash duplicates them EACH saving, so after a several savings Flash refuse to save at all (shows "Too big project ..." error).

I made a Post-It note movie clip that is draggable. I want to create a whole pad of notes, or at least simulate this. I thought the best way to do this would be to add another Post-It whenever the startDrag() is triggered.
I first tried creating the Post-It with symbols but didn't think I could dynamically create new ones this way. I then created a class and added it to the stage[code]...

I know very basic AS and ran into a small problem. I have a movie clip that I would like to be duplicated when the user clicks on it and then they can drag and drop it anywhere while the original stays in its place. Right now I have that working, the user can drag as many copies as they want, however when you release the clip you are unable to drag it anymore. "x" is my movie clip.

I currently have one movieclip in my library, but 4 instances of it on the stage. I was wondering what the best way to animate them so they can do things 'separately'- I'm not sure if Actionscript is the answer, but it's worth a try. I just don't want all of them to move when I move one of them (when I try to animate them inside their movieclip).Possible solutions: I already have one that isn't very... resource friendly. For every individual instance I can turn it into it's own Movieclip, so it isn't affected by the rest... but if I were to have many, many movieclips on the stage, that would quickly overflow my library. If that's the only way fine, but I'm sure there's a work around.

I wished to create multiple copies of a variable in a loop.such as:
var pots:String = thisString [i]
and then i wish to reference one of these loop generated variables.Now how would you set it up so you could have all those variables of "pots" had their own names so one could reference say: "pots1" "pots2" or "pots17" ? This kind of situation would bee seen in a situation where I would be bringing in many array values and assigning certain parts of them to the variables. such as array[i][name]

It's easy to share bitmap data between multiple Images: // target and source are instances of the mx.controls.Image class var content_copy:Bitmap = new Bitmap((source.content as Bitmap).bitmapData);target.load(content_copy);
But how to do the same thing for movie clips with vector grapics? The only way I've found is to load movie clip using byte data of another movie clip as the source.
target.load(source.content.loaderInfo.bytes); But it actually duplicates the content.

I am writing a maze program for school. I am using a 2d array to represent to location of walls for the maze. The background (for figuring out where a player can move) is not the problem.I am using this algorithm for places the images...
for (i = 0; i < 22; i++) {for (j = 0; j < 16; j++) {if (maze[i][j] == 1) {instanceName = "wall" add i add j; //for multiple names for each instance
duplicateMovieClip("wall", newname = "instanceName", 1);
setProperty("instanceName", _x, (25*i+13));
[code]....
What needs to be done to use many copies of one instance to build the visible part of my maze? I want to be able to have all pieces anmed "wall" instead of "wall1", "wall2", etc...which isn't working anyway.

I am having trouble using the name of given button to determine my loader URL. If my button is called yerBasicButton_bt ... I would like it to utilize a reuseable function to dynamically determine and load a URL named yerBasicButton.swf. In this manner yerBasicButton2_bt would then load a movie named yerBasicButton2.swf, and so on. So the function looks at the instance name of the calling button to determine it's URL.
stop();
unit133bd3ba_bt.addEventListener(MouseEvent.CLICK, getUnitSWF);
function getUnitSWF (e:MouseEvent):void { var swfLoader:Loader = new Loader(); swfLoader.x = 25; swfLoader.y = 368; var swfURL:String = e.currentTarget-"_bt"+".swf" var swfURLReq:URLRequest = new URLRequest(swfURL); swfLoader.load(swfURLReq); this.addChildAt(swfLoader, 0);}

Create a flash application which will be displayed on a web page which will read from a list of text inside an XML file and display them randomly with fade-in fade-out effects and also at random positions.My current approach to the problem is using a Dynamic Text Area which will read from the xml file, however I only got to the stage where the swf will read the xml file. Trying to get the fade effect and the positioning effect is proving very difficult for me.The sample XML I am working with:

<tagline>Global Jobs Pact</tagline>
<tagline>Green Jobs</tagline>

I want to create a rectangular box and add it to the stage. Easy enough.
At the moment I create custom classes and attach them to movie clips in the library via linkage, but in my example there is nothing to attach it to as it does not exist. How can I create a "generating class" like this?
I just want to call it with a call like
createRectangle() or possibly have some parameters createRectangle("200", "400")

I have the following code:
var page1:Branch = new Branch();
page1.y = 124;
addChild(page1);
I want to have the value "page1" to be dynamic, along with "Branch". Since there's a number of templates (up to 20), Branch is one of the templates. So it would be nice to use one instance creator. Also, I'm not sure how to get "page1" to be a dynamic value.
The closest to this that I've been able to find is:
star1sp.addChild(this["star"+star1Num]);
except that it doesn't fully address what I want to do. I tried adding in a bunch of "this[load_page]" and "this["page"+curpage]" to my code but had no success. I'm still on the prowl for the answer but wanted to put this out there. It's something I've tried to figure out for some time.

I would like to create a simple 2D interactive grid. The user should be able to increase and decrease the number of axis (both X and Y simultaneously) that compose the grid, and also the scale of the grid itself (Zoom in and Out).
If this goes well enough, I would like to be able to plot graphical content on the grid that visually changes as the grid itself changes. They should, in some way, be linked to one another and correspondingly affected by the same two parameters. This, however, would be a second step. I am more concerned with the base grid model at this point.

I got the first part to work. The only problem is when I click any buttons it produces errorTypeError: Error #1009: Cannot access a property or method of a null object reference.at resume_fla::MainTimeline/frame1()not sure what I have to do. All it's supposed to do is when you click a button the target movie clip plays frames 2 - 10 and the previous movie clip plays frame 11 - 20. Not sure what's the problem here.
