Dont output some message of error.What i do is create a new flash proyect save the fla file and then create a class where in the constructor i put the trace function with the message "hello world".I follow the instruction, and concepts, and understand everything, im not a new programmer i have experience with several lenguages.
View 8 RepliesI'm making a game which loads map .swfs at runtime. The maps will contain graphics and code, which can both vary from map to map. I've decided to make all the maps implement an interface, so they can all be used in the same way by the game. I'm using a .swc to contain the interface, like in this page.
I can get classes to work in the .swc, but not interfaces!
I'm using Flash cs5, and flashdevelop for editing, in AS3. Here's how I've been doing it:
1- create map.fla with a symbol called Map, and a Map.as:

I'm surprised that a XML loader works only if it is embed in a MovieClip class and not any external class.
I have my XMLLoader class and the loader didn't work.
I've added "extends MovieClip" and it worked.
I have a movie that reads class files located in folder called 'src' and has been working once I changed the path to absolute. for some reason now my movie has decided not to work.
this is how I create the path:
Go to porperties and click 'Edit' then clicking the AS3 'settings'. I then go to the 'Source path' tab and click 'browse folder' icon to the folder of the classes. having done all this my movie still does not work.
I can't make the tween to work. I've tried hundreds of tutorials and such (and they are all basically the same), I even followed the troubleshooting section of this tut with no results.If I download any file with that same script it works, if I copypaste it and do the exact same thing it doesn't. Maybe is something very simple that I just can't see but this is driving me nuts.
Partial code from flash tutorials:
Code:
import mx.transitions.Tween;
import mx.transitions.easing.*;
new Tween(ball_mc, "_x", Elastic.easeOut, 0, 300, 3, true);
I made a class named "fo" :
Code:
class fo {
function onEnterFrame(){
trace("HERE");
}
}
the swf file calling this file had:
Code:
var tr:fo = new fo();
Now when i run this swf ... it traces nothing ... ?( The as file is named fo.as and is in the same foledr as the swf file )
Basically I have a class called player.as The symbol "Player" is the only linkage it has.[code]It is trying to make the player, a movieclip onscreen, with an instance name "Player", move with the arrow keys. Sadly it doesn't work.
View 9 Repliesi'm trying to learn about clases, and i tried to make an easy XML loader, but i gotta a problem with the attributes that doen't take the value i provide with the att variable. it shows me on the trace statement like undefined, and for example if i change the atrribute instead of being dynamic, to be static, it does work.

I'm trying to use Greensock LoaderMax on a Starling Framework project, but since Starling have a lots of its own class, how I can make it work with other classes that is using the native class?
Exp:

will return the error:
Error: Implicit coercion of a value of type com.greensock.loading.display:ContentDisplay to an unrelated type starling.display:DisplayObject.
Is there any way to auto-import as3 classes (internal/intrinsic Flash Player classes at least) using Emacs ?
Looked for as3-mode and actionscript-mode but nothing working was found. as3-mode can import class if it is opened in buffer (but not *.mxml files)
The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.
I am creating a library in AS3. Inside the library I make use of a bunch of classes/packages that need not be exposed to the end user of my lib. I want to only expose one of these classes.
I guess my questions are:
1) How are libraries commonly distributed in AS3?
2) Is there a .jar equivalent in AS3 that developers can include, but will only have access/knowledge of the classes I've declared as public?
I have an actionscript project which uses visual symbols from an SWC. I have a CheckoutButton which has the following class associated with it (compiled into the SWC in Flash CS3).

I'm trying to import a class from a class that is located in another folder. How do you move up a directory? Using./ or ../ doesn't seem to work. Essentially I want to access a TweenLite Class but not from the document class. My class is at com/myName and the class I want to access is at com/TweenLite. import ../TweenLite doesn't work... I realize I could just copy and paste the entire Tweenlite folder again, but there's got to be a less duplicative way of doing this..
View 2 Repliesinheritance and building classes from other classes.
I have 3 classes:
gfxRoomText - changeable colour
gfxRomInter - changeable colour - interactive
gfxRoomImg - interactive - only image / no colour
The first two incorporate the same text field and functions to change colour. The second and third incorporate another class to interactive with. What is the best way of creating these classes using inheritance and how?
I have to use many custom classes for a project, each class includes lots of elements(methods,properties) and I generally forget their names when coding. Is there any editor which I can enumarate the elements of my classes after pressing "." like Flash's built in classes?

I've created a base class to house some basic functions I'd like to have across several movie clips in a game I'm making, however, when I link a custom class to the same movie clip I get the message; "The base class will not be used because the class specified is already defined and extends its own subclass. If you wish to use the base class, specify a class name in the Class field that will be auto-generated or enter the default base class 'flash.display.MovieClip' in the Base Class field." I removed the 'extends MovieClip' inside the Class but it still shows the message. Does this mean that I cannot use a custom class and a custom base class on a movie clip?

I am creating a clock with a textfield and I am loading fonts from a SWF library: the available classes/linkages are "Arial", "ArialBold", "MyriadPro", "MyriadProBold" and "Verdana".This is the line where I get the class from the SWF, and it extracts the class correctly

I have run across a strange problem. When I load products2.swf by itself, I can call the two "copy" files and everything works. When I open 0342.swf (the index page), I can switch between the home and products2 pages, but I can't view the "copy" pages.I'm guessing there may be some sort of conflict with variable names, but I have been messing with it for most of today.I have uploaded all of the FLA files to here:[url]....
If you make an swf file out of each of the attached items, and open the 0342 file, you will see what is supposed to be happening.

I have a button object that I need to scale to align with the variable width of an array of images.However, when I set the width in code, the button does not actually become that width. Tracing out the width gives me the correct value, but on screen.. it's off.
I've proved it to myself by scaling the same button object manually in the properties pane and visually comparing. Both of the buttons below have a width of 410.
Code:
navigatorDown_btn.width = 410;
navigatorDown_btn.x = (stage.stageWidth/2)-(navigatorDown_btn.width/2);
trace(navigatorDown_btn.width); // output: 410

View 8 RepliesI have a completed project (AS2) that contains a lot of FLVs. I burned it onto DVD and it works great on Mac (guide.app) and PC (guide.exe).Here's the web version of the project.http:[url]....Now, months later, I have to provide the project with source files (FLA's) and some other stuff - so I got an external HD, copied the files from the working DVD onto it. Running the guide.exe off of the external (connected to WinXP SP3) works just like running it off the DVD - EXCEPT for the FLVs which simply to not appear.
http:[url]...Everything up to that step works: When I click on "guide.exe", the "splash screen" opens showing the title and 4 buttons. These buttons are to choose a language and they work.When I select a language and click its button the GUI for the language with menus appear and they work. When I click on a topic from the menu, the topic's skin appears but the video inside the skin doesn't play. Everything works but the FLVs.
Even weirder - If I use VLC Player to open an FLV directly - the FLV will play. That tells me there is some path issue but how can a path change when it's compiled into the SWF? Besides - the paths from swf to flv has not changed when I copied all the files to the external.why the FLVs will not play on the external the same way they play when on the DVD?
been working with AS3 for a while. not and expert but not a beginner either. Somewhere in between I guess. One thing i haven't been able to get a grip of yet is using objects with AS3, so I'm doing some tutorials and experimenting to see if I can't become a better "programmer". So to start, i made a constructor, did a few traces- simple stuff. But now I'm trying to mess with a mc on the stage. in my fla file i have on the stage an instance of a movie clip of a box called "box_mc". I've exported is for actionscript with the class name of "box" and a baseclass of flash.display.MovieClip.
