ActionScript 3.0 :: Create A Class For Movieclip In The Library
Aug 3, 2009
I create a dot as a movieclip in the library. also i set the linkage to Dot class. Is it OK to create an external class Dot to associate with the movieclp inside the library? if it's ok. I would like to ask that is there any wrong in my code?
Code:
package {
import flash.display.MovieClip;
import flash.events.Event;
public class Dot extends MovieClip {
[Code]....
I'm creating a mask effect. i create 10 movieclip with a library class reference that appear on the screen with a random alpha effect. THe problem is that if i try the effect alone all works ok. if i mask the layer that contains the effect on an image i don't see the effect. i see directly the image masked with the boxes. i can't explain that because i've the effect first but it seems that when i test the movie the effect doesn't play and the boxes appear directly on the screen.
I'm having an issue using a class I've created as the base class for library symbols: I've created a class AvSkin which will act as the display for an instance of AvChild. It looks like this:
In my fla file, I created a movieclip in library which links to class MyMovieClip. I add some functions in the class. I fla file, when I drag the movieclip to stage, all the functions are working well. But I want to dynamic create the movieclip in stage(not dragging from library). This is the codes in my first frame of fla:
var tf:MovieClip= new MyMovieClip(); addChild(tf);
but all the time it display those error information: TypeError: Error #1009: Cannot access a property or method of a null object reference.
at MyMovieClip() at dragExample_fla::MainTimeline/frame1()
anybody can tell me what the problem is and how to dynamically create a movieclip which link to a class.
I want to create a movieclip class that subclasses another movieclip class and inherits all its properties (rather than having to rely on the include statement). In my project I'm using:An abstract parent class that extends a movieClip: "infantryDroid".[code]However everytime I try this, flash acts as though nothing was imported from the parent movieclip class.If I was to try the above code I would get the message that _root and speed (which were defined in the parent class) "are undefined".
I'm trying to write code that will dynamically add a falling leaf to a tree sprite every so-odd frames. But try as I might, I can't get the little retard to appear.[code]...
how to add a MovieClip from the library by a class i've MovieClip and i want to add it to the stage by a class note i've already a class and linked to a MovieClip and what i woona do is to addChild another MovieClip in the stage
I am working on a flash game that I am building in Flash Builder 4. I have a library of movieclips in the FLA file and need to create instances of these movieclips within objects of a custom class. I am unsure how to refer to the library of the flash file while in a class file. I also would like to call these movieclips dynamically based on the combination of two strings. I know it is possible to create variables dynamically with this[variableName]. Can I refer to library objects from the flash doc in the same way?
i try to migrate from as2 to as3 and i have one problem When i attachMovie from library (addChild in as3) and i add custom property its work fine.Here is ex.
Code: var i:int; for (i=0; i<5; i++)[code]....
when i attach to that symbol custom class in the library.i got the error: #1056:Cannot create property...
I just want to ask if is it possible to load a movieclip from the library using the Loader class together with the URLRequest and then use gotoAndPlay method?
Is it even possible to associate a class file to a movieClip manually placed on the stage without setting up the class linkage in the library? If so, how?
P.S. linking in the library then placing on the stage is not a viable option. Nor is using "addChild" from the library.
I've created a simple class that defines a scrollbar to scroll content. I've applied this class (ScrollBox.as) to a movieclip in the library as the Base Class.
Now, I'd like to add this movieclip to the stage with AS3. So for the Linkage, I've given the movieclip a class name of 'AboutBox'. This is the code I've written to add it to the display list[code]...
I have a MovieClip in the library with a class associated with it. I can instanciate the MovieClip just fine using code and add it to the stage without any problems. But how can I manually add the MovieClip to the stage and feed it the one parameter when it's instanciated? I've tried all the usual stuff but nothing seems to work:
var testClip:className = new className("helloworld");
testClip is the name of the MovieClip that's been manually placed on the stage.

Okay, so I decided to try putting some child movieclip switches into the .as instead of in the frames. After a lot of Googling and reading, I think I learned that each of those movieclips need to be in their own .as. Anyway, I tried to do it and the movieclip, which is located in the .fla library and does have export checked off, is not showing up when I play the file. The movieclip has this .as to itself:
I want to add MovieClips from the library at runtime onEnterFrame to create a trail behind the movieClip that is moving on stage: [Code]...
This just creates one instance of a movieClip "Follower". But how to make trail like effect - adding movieClips onEnter frame and positioning them according to "mcToFollow"?
I am making a Thumbnail class which is part of my Photo Gallery Package that I am building with the intent of automatically generating my thumbnails. I do not want to limit myself to just AS3 animations, I would also like the ability to use timeline animations. I have a system using "in" and "out" for frame labels which I find very efficient and I get stuff done quickly. So I created the thumbnails holder MovieClip with the animations and have it linked in my Library, however, when I try to pass it to my Thumbnail Class, I only get one instance and I need to create several instances.
Document Class ActionScript Code: var thumbCont:mcThumb = new mcThumb(); thumbNails = new Thumbnails(thumbCont);
Thumbnails Class ActionScript Code: var thumbContainer:MovieClip; public function Thumbnails(thumbCont:MovieClip,) { thumbContainer = thumbCont; }private function createThumbs():void { for (var i:int = 0; i < aThumbs.length; i++) { [Code] .....
I eliminated most of the additional stuff. What this does is that it doesn't create several thumbContainers, rather it just uses the one. So how would I be able to generate several of them? I can obviously create an Array with them and create them in my document class, but if I can avoid that and have my thumbnail class do it by itself, that would be perfect.
How do I reference a library movieclip in a class? I couldn't get it to work entering the name of the class in the linkage properties (as2 class name text field). The variable was undefined. I know I'm missing something....what is it?
can you declare multiple classes and then register each movieclip from the library to a different class? It isnt working for me.I created two different classes and created two entire different movieClips and registered each movie clips to a different class.However, I can only use on movieClip at a time, when I use the duplicateMovieClip... command to create copies of the movieclip, i find that only those movieclips, whose class i declared first, appear on stage.
Running Flash CS3, I've reviewed the lynda.com tutorial on building particle systems in ActionScript 3.0 to try and build some shooting sparks in an animation.I'm getting stuck at what I think is a really elementary point, but I can't seem to get past it.
Basically, all I'm trying to do at this point is create a class called Particle (which I will teach to do things that particles do a little later) link it to a MovieClip on the stage in my .fla file and use the particle's update function to move it across the stage in a manner defined in the instance (so I can later give different movement properties to each AS generated instance of the MC). I know there are easier ways to accomplish my base task without loading an external package, but this seems so strightforward that I must be doing something very simple wrong I just can't see so I thought I'd post the code here and see what I'm missing.
I start with a file called Particle.as in the same folder as my Spark Test.fla file.
In Particle.as I have the following code:
package{ import flash.display.*; public class Particle extends MovieClip { public xVelocity:Number; public yVelocity:Number; public function Particle() { xVelocity = 0; yVelocity = 0; } public function update():void { this.x += xVelocity; this.y += yVelocity; } }}
So I'm declaring that all particles are built with no motion, but if they are explicitly granted an x or y velocity, they will move by that much when the instance's update function is called in the timeline.
Then in my Spark Test.fla file, I have a small shape in a MovieClip called Spark. In the Linkage properties of Spark I have chosen to Export for ActionScript and Export in FIrst Frame. The class is called Spark and the Base class is Particle. For testing purposes I've dropped an instance on the stage and called it spark. Then in the actions layer in the first frame (the timeline is just the spark layer and the actions layer, one frame long each with no "stop();" so it should run forever) I have included the following code:
spark.xVelocity = 5;spark.yVelocity = -1; function updateSpark(event:Event):void{ spark.update();} addEventListener(Event.ENTER_FRAME, updateSpark);
What it looks like this should do is on each ENTER_FRAME Flash should call updateSpark which is a function that runs the update() event for the spark instance which is a instance of a movieclip that has an update event which moves x and y position by their relative velocity variables. This all seems pretty straightforward to me, but when I ctrl-Enter to test the movie, I get the following 3 compiler errors:
Particle.as Line 1: 5000: The class 'Particle' must subclass 'flash.display.MovieClip' since it is linked to a library symbol of that type. Particle.as Line 7: 1071: Syntax error: expected a definition keyword (such as function) after attribute public, not xVelocity. Particle.as Line 7: 1084: Syntax error: expecting rightbrace before semicolon.
I'm new to Flash AS3. I started making a game and I am a bit confused. Let's assume that I want to create a game that has multiple levels/modes, how can I do this in an object orientated way?
When i create games in other languages e.g. XNA C#, i create a separate class then create an object of that class within the main class and run the game based on a simple statement.
possible to create a movieclip and apply it to a class file that you could make? I mean...When you have a movieclip in the library in flash and have it be exported for actionscript...is it possible to do this for movieclip made in actionscript?
I'm using Flash CS3. Inside my document class, how can I create a child MovieClip that loads an image from a URL? what I did wrong? I tried changing the Main class to a Sprite, still not working.
googled it and hardly found any answer(seriously)need a quick solution for this:- How to create object from class that extends MovieClipSay i have a class name MC
