ActionScript 3.0 :: Creating A Symbol Within A Class?
Feb 13, 2009
I have a class called "playerClass" which I want to create multiple players from. I have made a movie clip symbol called "soldierOrange" and exported it for actionscript. I have also removed it off the stage. I have tried various bits of code to add it to a child and then the stage, read many tutorials but nothing has worked so far.
Here is my code below with the unrelevent code taken out.
Code:
package{
import flash.display.*;
public class playerClass{
I am having trouble incorporating graphical assets created in Flash with my haXe code.
In the Flash IDE, I've created a symbol with the linkage name "MySprite". I compile this into assets.swf. I know that to use symbols in this .swf from my haXe code, I need to add the following option when using the haxe compiler:
-swf-lib assets.swf
I'd now like to write a class called "MySprite" which is associated with this symbol, like so:
class MySprite extends Sprite { public function new() { // ... } }
Basically, I'd like to achieve something similar to the technique presented in this tutorial:
Library symbol "Card" is linked to class "Card" which extends "MovieClip". Library symbol "Card" contains a card background image.Library symbol "Ace" is linked to class "Ace", which extends class "Card". Library symbol "Ace" contains a TextField with a big letter "A".So we have Ace extends Card which extends MovieClip. Ace therefore extends MovieClip, but does not DIRECTLY extend MovieClip.When I drop an instance of Ace on the stage and compile the clip, all that shows up is the big letter A. However, I expected the background image from Card to be included, since Ace extends Card, and the Card symbol contains the background.It seems like Flash ignores symbol content unless it belongs to the top-level class being instantiated.I think it's LAME that one symbol can't extend another. The IDE could easily draw Card as a non-editable background while I'm editing Ace which extends it, and it should instantiate Card's content and then Ace's content when an Ace is instantiated.
When we create several instances of the same symbol, can we instantiate them using a single variable, or is it required to use a different variable per instance? In the following example, the "var c:Circle" is used 10 times to instantiate the same MC symbol. How can those be altered or removed one by one if all instances refer to the same variable name?
I am creating an image gallery with thumbnails on the right inside a symbol so that they can all fade in at the same time, and the bigger images on the left that also fade in. I can only fit 8 thumbnail images at a time, and want to have more than that. So I'll add an arrow below the thumbs so that when you click on it, you can see the other thumbs. I have the first 8 thumbs on the first frame of a symbol and the rest on the second frame.
My problem is that the symbol that contains the thumbs is a graphic symbol, so that the thumbs in it, that are button symbols can be clicked on. I tried using button and movie clip symbols for the thumbnails container but then the buttons (thumbs) can't be clicked any more. That was not a problem till I had to add more than 8 thumbs, cause i need to give the container an instance name, and graphic symbols can't have one.
Here is the link to download the .fla [URL] In case I didn't make my self clear, what I need is to know if there's a way to have a movie clip or button symbol that can have buttons in it that can be clicked on.
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'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 have a simple progress bar symbol (ProgBar) in the library of main.fla. If I don't define a class and allow Flash to assign a placeholder class of ProgBar, then the symbol displays ok using progBar = new ProgBar();addChild(progBar); If I define a class, even the basic empty version below, I get the following error: ReferenceError: Error #1056: Cannot create property percent_txt on ProgBar. at flash.display::Sprite/constructChildren() at flash.display::Sprite() at flash.display::MovieClip()
Class code: package { import flash.display.*; import flash.text.*; public class ProgBar extends MovieClip { public function ProgBar(): void { } }}
percent_txt is a text field I've given an instance name to. If I delete the text field (or its instance name) the error changes to reference the next item in the symbol and so on until there are none left!
Im just learning classes and objects.... and read that a movie clip is (or has) a movie clip class... So I'd figure that buttons and graphic symbols also are classes? If yes, why are they called 'symbols' instead of 'classes' by Flash dialog?
If I've already specified in the symbol's package which class the symbol's class extends, do I still need to specify the base class in the symbol properties dialog?
There is a simple method of linking a symbol to a class in flash cs5 in the gui designer. But how can i do the same thing in actionscript alone using code because iam not using flash cs5. Iam using notepad++ and flex compiler.
I'm trying to write a custom class for a library object. for example i have a movieClip in my library and there is a textField in it instance name is textField .
i exported my clip for actionScript and i write class definition like "com.xxx.MyClipClass". it's ok, there is no problem. but when i want to access to textField in MyClipClass like this.textField.text ="abc" i got an error undefined property.
I am making a platforming game for an assignment and I have a problem with this bit of code:
package { import flash.display.MovieClip; public class PlatformTest extends PlatformManager
[Code].....
All platforms are loaded into this class, and there are currently 2 instances within a Level movieclip. It's kept at 2 for seeing if it works purposes. This code basically gets the y values and x values for all sides which is used for collision detection purposes, loads it into an array, and the array number is incremented.
I'm not exactly sure if this method works or not, and I don't even know if every instance of the symbol is being loaded into the array, but is this code right, if not how do I fix it?
I am currently develoing a flash game and I am trying to spawn 2 different symbols from a class. I have a Class called 'PLayerClass', which contains a variable called 'hero' which I assign a symbol to. This works fine with 1 symbol but I have no idea or if it is possible to assign a different symbol to the variable 'hero'. The 2 symbols are 'soldierOrange' and 'soldierGrey'. For both of these symbols I have matching classes (ie. soldierOrange.as).soldierOrange.as
i have been working on this project. I made a class with a empty blank symbol.
package { public class imgHold extends MovieClip { public function imgHold (imgSrc:String)[code]....
I want to be able to add this class on my stage and put in a string in the contructor parameter and the class will display w/e symbol accordingly. How would i make this class link to different symbols depending on the parameter in the contructor?
I am trying to create a simple drag and drop Flash program where a user can drag xmas ornaments onto a tree. Instead of being able to drag the ornament once, I want a function so that every time an ornament is clicked on, it adds a new ornament of the same class to the stage where the ornament is clicked. Currently I have this working but there is one problem. It is not dynamic. Looking in the "drag" function, I have chosen the class "Symbol31" as the default ornament that gets added. Instead, I want the ActionScript to read the class of the ornament that was clicked on and to add that class, not "Symbol31" everytime.
Code: public class DragDrop extends MovieClip { private var originalX:Number;
i have a MainTimeLine.as Document Class using as3 in flash cs4.it beginning looks like:[code]where the as file is declared in the Document Class of the primary fla file. under this primary fla file, i have a MovieClip symbol which points to another fla file. well this file declares a Class Linkage and i can access the properties and objects of the embedded symbol fine from the MainTimeLine.as script file.however, i have the above public player variable defined, as shown above, in the MainTimeLine.as code.i am having trouble accessing the player properties/methods from the embedded symbol fla file. how do i do that?
Im having problems with classpaths. I have used them before with "import" but I'm not able to link a class directly to symbol in the library.
I have a class c:/myfolder/src/myclass.as . In prefernces > AS3 settings, I have c:/myfolder/ as default classpath. I click linkage on the symbol and enter src.myclass . When I click the checkmark, it says 'class not found'. I am able to do: *import src.myclass; and attach the class to an instance on th stage. That works fine, but thats not what I need to do.
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:
I am trying to create a dynamic class from a symbol in an embedded swf, basically I need to be able to add arbitrarily named properties for some exciting math, but it appears the only way is to create a dynamic class.
[Bindable] [Embed(source='ExternalAssets/Assets.swf', symbol="assetName")] private var AssetNameObject:Class;
Can any answer the following questions and maybe point me to a "for dummies" tutorial on 'Classes'. I have the books but they have seemed to disappoint me. Unfortunately I can never ask "why" when reading a book.
1) Does a Class file need to be attached to a library symbol?
2) How do you know what to import?I know this sounds funny but should you always import flash.display.MovieClip? I just want to create a line using a class to begin with and call it from a flash swf with two parameters (start and end).Wouldn't it only need to be a import flash.display.Graphics
3) What is "Base class is final."? Anybody had this error before?[code]
i have a fla document with a symbol in the library (which i set Linkage ID). i have also two classes : for example parent and child that parent class in a loop places some child copy on the stage.
how could i send my symbol in the library to the child class (from parent class) properly?
Code: //in fla document var myParent:parent = new parent(mysymbol); //create 7 child myParent.createchild(7);
i need to have NEW symbol copy in for each child instance.
I have a mc in my library called SimpleButton and in the class path for that mc I have the path to my class: com.company.ui.buttons.SimpleButton.
But when I try to instantiate the symbol using the following code, it does not appear on the stage.
Code: var simpleButton = new SimpleButton(); addChild(simpleButton);
The code works fine when the mc class path is just SimpleButton, the symbol is added to the stage. However when I try to use my own class, the base class disappears from the linkage box in the mc properties dialog and the symbol does not appear on the stage.
I created a movieclip symbol and exported to actionscript, I created the .as file:
class BRIQUE extends MovieClip { function BRIQUE() {
[Code].....
"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 ?
