I'm new to Adobe Flash. I'd like to create a button or component in Flash Professional using MovieClip and add label to it, and build my own button with special functions.
And i'd like use ActionScript to edit code. I faced a problem: i can not edit all code of my component (that cotains several ui-elements) in one AS3 class. I create empty document, add rectangle to it, then convert it to symbol. Next, i go to Advanced ActionScript 3.0 Settings of IDE, add path to folder where i put my Class.
Then add MyClass to Document class in that window.
But when i add new elements to the document, it doesn't appear in MyClass.as
Is it possible to edit complex component in Flash IDE in one ActionScript class ?
Sorry for a long explanation and for my poor english.
I create empty document, add rectangle to it, then convert it to
symbol.
Make sure symbol is type: MovieClip. Give it a name you prefer (no space is good idea). Further down (see Advanced section?) there is section called Linkage click "Export for ActionScript" and remember the name shown in Class box (you can edit it) and just click OK. No need for folder paths etc.
Lets assume the name used for Class is : myComponent
Now you can use it in your code. To make a document class open the Properties panel (ctrl+F3) and just type a name example Main (no extensions) and press enter and then save FLA and secondly also save the class code (it will ask for a file name so use as Main.as).
Now If you click that pencil icon in properties you will be editing class code (Main.as) for the FLA document and it knows your component if you reference it by code:
public var test_comp : myComponent = new myComponent (); here test_comp is just a quick reference name. Use your own preferred reference name.
You can edit the MovieClip of myComponent by right-clicking and choosing "edit" (not "edit Class"). Now you can add/draw different things and even convert them to Graphic or MovieClip and give them instance names. A MovieClip object is like a mini-stage so it has its own unique timeline and you can work exactly like if this was the main stage (but without actually affecting main stage).
If you add something to Component MC such as drawing a circle (as some button?) and convert that circle to MC or Graphic type with instance name circle1, in the code you access that as:
test_comp.circle1.alpha = 0.5; since test_comp is your code's reference name for that myComponent MC in the Library.
After testing the above example... now begin your own component.
Remember... If an object is inside the MC access it via it's instance name and if you need to addChild it from the Library instead then use its AS3 linkage name.

Previously in my code, I had a Variable, Chip. Chip moved around the screen and everything was fine.
var chip:Shape= new Shape();
chip.graphics.lineStyle(0,0);
chip.graphics.beginFill(0x3333FF,0.8);
chip.graphics.drawCircle(0,0,10);
chip.graphics.endFill();
was the code to make chip. Now I've make a movieClip and I would like to use the movie clip instead, so I know I'd start with something like
var chip:movieClip;
but I'm lost after that. How would I be able to use him in place of making the shape?
So I'd guess that you are using Flash IDE and have created a movieclip for your Chip that is now in your library and you don't know how to add it to the stage :)
Right-click on your movieclip in the library and select "Properties". In the advanced section select the "Export for actionscript" checkbox and give your movieclip a linkage name in the "Class" Input field, for example "Chip". Leave the "Base name" as MovieClip.
Now your movieclip is accessible via actionscript and you could add it to your stage:
var chip:ChipMC = new ChipMC();
addChild(chip);
trace(chip.x, chip.y);
Here's the situation:
Making an app in Flash CS6 that has 11 frames. Some frames have actions dependent to that frame and then there are some global actions. There are no external classes, everything is incorporated into one flash file.
Now I want to incorporate AdMob and found an offer that should work for me, but it calls for setting a document class linked to external AS file. Doing this messes up my timeline based actions.
I am more front-end that back-end when it comes to designing/programming. So, my question is: How can I incorporate this external admob actionscript into my flash document file without messing up my current scripts? Is there a way to remove it's package attributes and put it on the timeline?
Hope this description wasn't confusing.
Thanks!
Some brief about document class & classes & timeline :
Consider the whole stage as a movieclip. Now the document class would be a user defined, external class for the stage movieclip. When you don't specify the document class, flash uses a predefined one, which derives a plain movieclip class. The frames added from the IDE are converted as calls to addFrameScript and the script in the frames are scheduled to run at an interval as per the frame rate (timeline). Even the shapes you draw, images you add, everything goes in as code in the frame scripts of the stage movieclip.
Now if you add a movieclip onto the stage, the above process is repeated for it as well. You may set a class or derive from an existing class for any movieclip. The class will be initialized when the movieclip instance is created, Be it frame script or place the movieclip itself in the frame.
Now to your question.Any frame script can access the external class as well. So if you have an external class named AdMob in a file AdMob.as, lying next to the fla, you may call it anywhere, in any frame as:
new AdMob()
However you must take care of the package name & path. So if the package for AdMob is abc.bbc.AdMob then the location of the as file should be abc/bbc/AdMob.as
You may import the whole package as :
import abc.bbc.*;
So I've been following this tutorial on AS3 and Flash. Its been going well until, note I have tried to contact the writer of the tutorial and had no reply. Here's what it tells me to do;
Right-click PlayScreen in the library, select Properties, and check Export for ActionScript. This time, instead of accepting the default value, enter the name of your document class. Click OK.
So it pops up an error, first we’ll have to make a new document class, since no two different objects can share the same class. Cancel the Properties box.
Hit File > New and select ActionScript File. Enter the (by now familiar) code.
Save this in the Classes directory as DocumentClass.as. (There’ll be no confusing the purpose of this file!) Now, back in your FLA, change the document class to DocumentClass.
Check everything’s fine by clicking that pencil icon — if it’s all OK, that should bring up the AS file that you just created.
// So this bits all fine, its the next that i'm stuck with:
Now you can set the PlayScreen‘s class to AvoiderGame. So do so!
// So I go ahead into the properties and change the name but then it pops up with the same error as before: 'Please enter a unique class name that is not associated with other library symbols'
What does this mean!? How do I resolve this!?

Its hard to tell what you are trying to accomplish without knowing what all the parts you are referring to actually do, which are objects in the library and which are classes, but maybe this can help:
First of all, document class in AS3 typically refers to the project's main set of code that initializes the app. This class can be called anything but is often called Main, and is entered in the property panel that is displayed when you click the projects main stage in the field called class.
Now, when linking a class to an object in the library, its a little different. In the library object's property panel, tick the box for Export for Actionscript, and put a unique name in the top box. This is what you reference in your code to call it, like new somethingOrOther() or using the pic below as an exaample, new Ball(). The second box is the base class, pathed to where it lives in your code base. This is the class you will write that actually controls the object you've linked the class to. Giving a linked object a base class and a unique identifier allows you to use the same base class for multiple linked objects.
Note that when you do this approach, Flash will warn you that there is no class associated with Ball and one will be created for you. Don't worry, this is normal behavior. If you set this up properly, your object will still be controlled by its base class.
What I am trying to do is add a MovieClip which I have created, but deleted from the actual stage itself, from a seperate class to a sprite which I declare in the document class.
The link between the main document class and the others works fine, as well as references to the stage, from the class in question.
It is only one line of the function which is giving me the error: Type was not found, or is not compile-time constant:SequenceA
I have already tried changing the settings for 'Export for Actionscript' in the library properties and still get the same message every time.
Pretty lost with this one so any help is appreciated. Cheers!
What have you set as the "Class" in your Export for ActionScript settings? It looks like you're trying to refer to an instance rather than the class itself. For example, mc is an instance of the MovieClip Class.
Assuming you've chosen the Class "SequenceA", you would do this instead:
var seqA:SequenceA = new SequenceA();
There's a little bit more detail about objects and classes here.
I started reading this tutorial: http://active.tutsplus.com/tutorials/actionscript/creating-a-reusable-flash-uploader-with-actionscript-3-0-and-php/
I'm using FlashDevelop, and I pasted the full code into an ActionScript file. The errors I'm receiving are like this:
C:\Users\tempus\Documents\uploaderas\Uploader.as(30): col: 4 Error: Access of undefined property select_btn.
select_btn.addEventListener( MouseEvent.CLICK, browse );
^
C:\Users\tempus\Documents\uploaderas\Uploader.as(31): col: 4 Error: Access of undefined property progress_mc.
progress_mc.bar.scaleX = 0;
...
I understand that the errors appear because the objects have not been declared ( and they appear to be instantiated from somewhere ), but I don't understand how/what should I include to declare them. Could you point me towards a solution?
It's because the buttons are created in the Flash IDE (as the tutorial was meant to be compiled using the Flash IDE). Since the buttons don't exist in the code aspect you get that error.
You can either create the elements yourself via code, or use the Flash IDE and export a swc/swf of the neccessary UI elements and include that in your flashDevelop project. I'm assuming you'll want to do the latter -
in the Flash IDE, open the .fla, open the library panel, find the progress asset, right click it and bring up the properties. Check the "Export For ActionScript" option, then in the 'Class' field give it a unique name like "SelectBtn". Do the same for the 'progress' asset (only a different class name like 'ProgressBar'). Go to the flash publish settings, and on the flash tab select 'export swc'. publish the file and place the published swc in your flash Develop project folder (traditionally the lib folder of your project).
In Flash Develop, right click your swc and choose 'Add To Library'. (You may need to right-click again and go to options and choose the include completely option). Now you can access those classes you setup in Flash. Then in your code, declare and initialize the display assets:
public var select_btn:SelectBtn = new SelectBtn();
public var progress_mc:ProgressBar = new ProgressBar();
You'll also need to do that textField too. It would be easiest just to do it in your code though.
public var label_txt:TextField = new TextField();
Keep in mind you'll need to manually position and use addChild on all three elements this way. If you want to keep the positioning that's in flash, just select all the elements on the stage and press F8 to convert them to a MovieClip. Then in the library setup linkage the same as the others and give it a class name of something like "DisplayAssets" and export a new swc. Then your code would look like this:
public var select_btn:Sprite;
public var progress_mc:Sprite;
public function Uploader(){
var displayAssets:DisplayAssets = new DisplayAssets();
addChild(displayAssets);
select_btn = displayAssets.select_btn;
progress_mc = displayAssets.progress_mc;
//the rest of the code
}
