Professional :: Warning: All Instances Named 'head' Will Be Automatically Declared As JessHead In Symbols That Use Character As Their Base Class
Nov 3, 2010
In my library I have:A Sprite named Emily of base-class "Character" with a sub-sprite labeled "head" of auto-generated Class "EmilyHead".A Sprite named Jess of base-class "Character" witha sub-sprite labeled "head" of auto-generated Class "JessHead".
Flash compiles with the following warning: Warning: All instances named 'head' will be automatically declared as JessHead in symbols that use Character as their base class. In symbols that are linked to user-defined base classes, instances with the same name must be of the same type. And then the runtime error:TypeError: Error #1034: Type Coercion failed: cannot convert EmilyHead@3a0d1e81 to JessHead. at flash.display::Sprite/constructChildren() at flash.display::Sprite()at Character() I can turn of auto-declare stage instances in the Actionscript 3 panel, but then I have to manually add a public var for all sub-child's, such as the head sprite. But then at least everything works as expected. This is more setup than I'd prefer to do, but everything else about this workflow is very fast & easy. What can I do to sidestep this error, while keeping the same workflow?

I frequently create a lot of Library Symbols, export for Actionscript, letting Flash auto-generate the Class & extending a custom base-class in order to give them all custom functionality w/out having to create a Class for each, and/or without having to create a FactoryClass for instantiating X number of ClassObjects for each Symbol to be added to.It's really fast for prototyping, and with this workflow I've only hit a few obstacles. Those are:
1 - If the Symbol has children you cannot give the children instance-names, else the compiler gives an error related to automatically declaring stage instances. Two workarounds for this are that you can uncheck automatically declare stage instances, and do it manually in your base-class. or you can avoid using instance-names, and use getChildAt().
2 - If the Symbol is a MovieClip, the timeline doesn't inherit the base-classes imports. I don't have a workaround for this.are these limitations that could be addressed by Adobe's Flash team, or are they limitations that are unavoidable without altering the workflow?

I'm slightly new to Flash CS3 + AS3 combo, so its more of a lack of practice question. My question stems from the problem described here http:[url].... . Note, its not the same problem, its a new one.The Problem ,So I have multiple library assets (which are on teh stage) and I want to assign similar functionality to all of them.
Attempt 1: So I create the n assets, create a custom class in AS3, link them to Flash CS3 and obviously enough it gives me the error that multiple assets can't be linked to the same class.Obvious enough to understand (well not completely, because from a programmers background it doesn't make sense).
Attempt 2: Same as attempt 1, but instead of linking all the assets to the same class I make the base class the same class, and let the derived class be dynamically created by Flash on compile time.So the linking works, but the problem is, in my base class I have a method which does something (say an tween) on a child of the library asset. So if the assets on the stage/library are called asset1, asset2, asset3 (same name for asset name, class name, id name), each of them has a sub-movieclip called ... say 'foo'. now if I manually wrote a class for each asset, I could do 'this.foo' to play with the sub-movieclip. However since this functionality is in the parent class, I'm unable to do it.
P.S. If you're form a programming/OOP background, its basically a abstract class problem. My Base class knows how to doSomething(), but it needs aSomething, which is defined in the Derived classes. However I found out that AS3 classes don't support virtual(C++ )/abstract (Java) in the true sense of the word (unless I missed some obvious documentation).

I'm a very new user to AS3 and I'm attempting to migrate a site from Flash CS3 to CS4 on a Mac. I keep getting the following compile warning: "Warning: Actions on button or movie clip instances are not supported in Action Script 3. All scripts on object instances will be ignored." This is very confusing to me. I thought that scripts could be attached to both frames and objects? Is this a bug that is a result of switching from versions? Or is this warning true; and I have to abandon all uses of attaching scripts to objects on the stage?
Also: Can anyone illuminate me on the keystroke to call the actions window in AS3? It is supposed to be the F9 function key and another that I can;t locate on my keyboard!? As I said,I'm a very new user, so be kind!!

I'm writing a series of Search windows for an application. I create the FLA files on the stage, each has 3 simple buttons: next_btn, prev_btn, and close_btn. Those all have event listeners which call findNext(), findPrev() and closeWin() respectively. Each search window looks for different things, some with a text box and some with a combo, etc.
So I have a base class com.search that extends Sprite and adds the eventListeners at startup (actually, on addedToStage). Like this:
function isAddedToStage(evt:Event){
next_btn.addEventListener("click",findNext); prev_btn.addEventListener("click",findPrev); close_btn.addEventListener("click",closeWin);}
[Code]....
If I add the event listeners in the derived class rather than the base, it works fine. But that seems to defeat the purpose of inheritance, plus it infers that I won't be able to derive new classes/swfs from those derived classes.
how does one reference objects created on the stage from a base class of that document's class?

I am stumped as to how to use an animated symbol repeatedly in a timeline while being able to alter its visual qualities without breaking the animation motion.I make a simple 3-layer animation of a body with two legs doing a walk cycle in place.I convert the completed animation as a new graphic symbol in the library.
I can then drag copies of that animated symbol to different timeline layers and alter their overall scales or give them each additional motions with a motion tween so various versions of it can move across the stage independently with tweens while keeping the walk cycle movements of the symbol.
I can change the colour properties of the added symbols but this only affects the whole image, so if the object had a body and legs in different colours, altering the properties changes all of the body parts to the same colour.Doing this does preserve the walk cycle motion, but the new object looks crude because it has become all one colour.I can then alter the visual properties of the components individually, but then it loses its animation motion.Whether I just group it again or convert it to a new symbol, it has lost the animation motion (the walk cycle of the legs) of the original. how to make such an animated symbol so that I can reuse it in the timeline while changing its visual properties (so it looks like a different character in the story) and yet keep its original animation motion.I have tried to duplicate the symbol and to copy and paste the motion but nothing seems to work.

I have asked this question in another forum but haven't got an answer yet. I have just started using Flash CS5 recently and have a question about the classic tween. I have noticed that when I make a classic tween Flash automatically makes symbols out of my grouped objects. I have worked with previous versions and it was sufficient to just group my objects on the stage to make a tween. Is there a way to turn this feature off? I'm an animator and it's very annoying and messy to make a symbol out of all the objects I want to animate.
When I add a tween (CS3) I always used the Properties panel and choose "motion" from the tween settings. This way there's no symbols added in the library. Just noticed that there are also tween symbols added if I add a tween using right Mouse click or via the menu Insert>Timeline>CreateMotionTween. Never used this before. But I can't seem to see any tween settings on the properties tab anymore in CS5.

I have this Fla which contains a symbol that is linkaged to a certain class that is in my project. That class inherites a base class named CMovieClip which resides in one of the libraries that is in the class path (and inherites from MovieClip).Of some reason, every change that I do in the base class doesn't seem to influence the resulting linkaged class, much as if this library is cached somewhere that I can't feagure out.I tried to create the same conditions in a separate Fla but it does not repeat the issue.I tried to duplicate the symbol but the issue isn't solved that way.

This question stems from this question that I asked yesterday.I've followed Theo's advice and created a .swc with all the common classes and added the .swc as an external library to my module .swf. This all seems to have worked smoothly--I don't get TypeErrors and my classes are all present in the catalog.xml of the .swc file when I unzip it--but now I've encountered a new problem: when I try to link a symbol in the module .fla's library to a base class from my .swc rsl, it says the base class definition can't be found in the classpath. The whole reason I want to use rsls is so I can do this,If I now include the project's source path or the .swc in the normal (not external) library path, will that cancel the sharing benefits of the rsl, or will the compiler still know not to compile the shared classes into the module .swf?

I'm working on an isometric-view prototype game, and I thought a good way to do the collision detection would be to put four empty movie clips on each of the character's base corners (it's a cube), convert those corner's _x and _y to the Stage, and go from there. Problem is, how to get it to work.My character is on the stage in an otherwise empty "clip" MovieClip. Here's what I have inside my character:
Code:
onClipEvent(enterFrame){
var point:Object = new Object();
point.rightX = right._x;[code]....
Whenever I trace any of these, it always traces the local coordinates. Otherwise, everything is fine.

I'm attempting to use CS4 (PC/Vista, if that matters) to create a SWF file that will basically act as a "library" of commonly used symbols. This SWF would be loaded at runtime by other SWFs, which could then use the symbols within it, including all art and code assets.

I am using CS3 / AS2 and was wondering if it was possible to load a movie into a symbol, not just an instance of that symbol, from the main timeline. I tried exporting the symbol for actionscript then using loadMovie but I suspect that is not the correct way to go about this.
PHP Code:
symbol.loadMovie("urlToMovie");
Is it even possible to do this or do I have to change every instance of the symbol individually?

Should I use Movie Clip or Graphic Symbols for Character Animation? What do people who make TV shows use. If I'm not planning on manipulating any symbols with ActionScript and I'm not using a symbol that requires it's own time line like a walk cycle, is there any reason to use movie clips symbols? If I put my animation on the web will it download noticeably faster if I use graphic symbols instead of movie clip symbols?

My workflow usually goes like this: i create a symbol in Flash IDE with textfields, containers, etc. Then I select "export for actionscript" and type in the classname (automatic declaration of stage instances, of course, is off). Then i create a corresponding classfile in FDT and declare all this textfields and other objects that are in my symbol. This is pretty routine and boring process that takes a lot of time.
Is there a way to automate it? Maybe some plugin for flash IDE that will automatically create a class file based on symbol exported for AS?
Update: So, following the answer Pavel fljÅt provided, i wrote my own command to accomplish this task.[URL]..

I understand it's probably best practice to name your custom classes differently than the built-in AS3.0 classes; however, what kind of problems could I run into if I don't?Specifically, I have a class which, ideally I want to name DataProvider. But, as you know, there is already a DataProvider class on the Flash platform (used for list-based components and such).Now, I don't think I'll ever use BOTH of those classes, so I'm assuming as long as I reference the correct DataProvider class in my import statements I should be ok?What if I DO need to use both, is that even possible?

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 created a movieclip with a star. Then, I creates a document class and I named it as Main.as.
In that document class I wrote:
package
{
import flash.display.*;
public class Main extends MovieClip
[Code]....
I´m not posting here all the code, but you can easily see that I´m using x_origin and y_origin variables to keep the original position of the movie clip. I will use them to move the star back to the original position.
The problem is that instead of being 20 and 30 respectively, tracing them I see that they are both ZERO. So when I drop the star, instead of going to x=20,y=30 it moves back to x=0 and y=0. I´ve to get the star position relative to stage, but I can´t find anyway!

I am creating a Weapon class for a game and the weapons itself will be the sub classes. The sub classes will hard code some values (such as max ammo and the weapon name).
I trying to access this declared data in the base class constructor, at the moment it's not outputting the values. Is this possible?
I've broken my Weapon class for simplicity:
ActionScript Code:
package
{
import flash.display.MovieClip;
[Code]....
My current workaround is creating a protected method in the base class to trace the information and calling that method in the sub class's constructor, this works fine but this doesn't seem like the most efficient technique?
