ActionScript 3 :: Conflicting Scope - Global Functions And Class Methods Of Same Name
Jul 6, 2011My question deals directly with ActionScript 3, although it could possibly appear in other languages. Consider the global trace function found in AS3. Calling the method requires no imports and is globally available from all classes.
class A {
public function A() {
trace("Hello, A!"); // Hello, A!
}}
Now, what if I create my own class method of the same name? In AS3, if I have a class method trace and then make a call to trace elsewhere in my class, the call is made to the class method over the global function. Essentially, I've blocked my ability to call the global trace method.
class B {
public function B() {
trace("Hello, B!"); // no output
} public function trace(s:String):void {
// do something else.
}}
Now, I know the obvious answer is to say, "don't create a class method called trace." But what if I'm unaware of the existence of the global trace function? Or what if I have a desire to "override" or "block" the global function? Is doing so bad programming? Or is this just another example of how AS3 is a poor object oriented language?

ActionScript 2.0 :: Accessing Outside Variables From Functions?
Aug 1, 2004how to access variables that are declared in a movie clip from a function declared in that same movie clip.
i.e.

var int2 = 2
[Code]....
I'm trying to do this in the main movie clip of a movie that I plan on importing dynamically in another movie. I've tried to use this.int1++, but I think that flash was looking for a variable that belongs to "myfunction" when I did that. I could just use _root.int1++ but like I said, I plan on dynamically loading this into another movie, in which case it would be pointing to the wrong movie.

Nov 4, 2009I'm trying to find a way to have global functions in my as project, similar to how flash does with stuff like the util functions (describeType()...), where you can just call the function wherever you need it. For example:
[Code]...
So when I call Test(), it prints out "hello world" fine. My problem comes in that I can't change the name of the Test function, and I can't add any other functions without compiler errors. Is it possible to have a load of global functions in one file, or do I have to split them up into separate files like in the example? Also, I know that I can make a Global class and call static functions like Code: Global.doSomething() but I'd like to know if there's a way to do it as flash does it (describeType(), getDefinitionByName(), etc), or rather, how does flash do it?

View 1 RepliesActionScript 3.0 :: Import External Functions / Methods
Dec 29, 2010I have a main actionscript file import other actionscript files into it to use their function. From the tutorials and training videos I have, other external classes apart from the document class always link to an object in the library or an object in the main.as is an instance of the other class, for example:[code]
The problem is I'm not creating any variables from the external class but only want to use the functions from it. When I test the movie, I get error 1180: Call to a possibly undefined method isPossibleNo, which is inside class ProjectileNo that is imported already.So my question is how I can use external functions without creating a new instance of the external class because they only hold calculation functions.

OK. I then need to run through each of them and check for a collision with an object from the main stage (called redDot), which I pass to a method (called doDamage) within the class. I'm using the following code:

It just won't work. I've tried altering the code to:

ActionScript 3.0 :: Accessing Superclass Methods On An Externally-loaded SWF?
Jul 27, 2009I'm trying to set up a large project that has a "shell" application that preloads and eventually displays a bunch of SWFs as a "slideshow". Each SWF could be authored by different people but will reference a base document class so they exhibit consistent behaviour. One of these behaviours is to be able to localise the slideshow into different languages. Since each SWF could have a different number of textfields that need to be localised embedded into their main timeline, the SWFs each must declare their stage instances in their document class. In order to implement the common functionality (such as a "localiseText()" method), I have decided to package all common functionality into a superclass (what I'm calling "Base Class" in this example) and using a subclass as each slide's document class.
This Example:This is a simple example I set up because in my actual project my compiler was throwing a coercion error when I tried to cast the Loader.content as my external class. The structure of this example is the following:
+ loader.fla : this is the main "shell" application.
+ SWFLoader.as : the Document Class for loader.fla
+ external_1.fla : this is the external SWF file that will get loaded and displayed
[code]....
I've set it up this way because a hypothetical external_2.fla might have different public variables to declare its stage instances so would need a separate implementation of ExternalBase (presumably External2.as).
The code (in reverse):
base/ExternalBase
[code]....
This just sets up the localiseText() method which is used in this example to change the contents of the text field. Since we don't know the name of the text field in the particular slide's timeline, we have to ask for it from the subclass' implementation of getLocalisableTextField(). We declare an abstract function here that needs to be overridden in the implementation.
[code]....

ActionScript 2.0 :: [Flash8] Setting Callback Functions On An Object Methods?
Jan 12, 2006Been doing some actionscript magic lately, done a nice interpolator class. The class, whenever an update occurs, calls a previously specified callback function. Normally, setting a variable of funCallback:Function and calling it works fine. However when I wanted to specify an *object's method* as the callback for the interpolator, it apparently called it as if it would be a static method.
And it isn't.What I need to do, simply speaking, is to be able to call an object's public method, having just th object's reference and function name, just like the second variant of setInterval does ( the one having "object, string" as the first two params, not "function").
