I have a general / somewhat newbie question. Is it better practice to call a function from another class like so:
[Code]...
Does one way free up more memory or enhance performance?
When I try to use this code to call a function for every instance of a certain class I get an error saying that there is a "call to a possibly undefined method removeInstance through a reference with static type flash.displayObject".
Code:
for (var i:int=0; i<=numInstances; i++) {
if (numInstances!=0&&getChildByName("b"+i)!=null) {
getChildByName("b"+i).removeInstance();
}
}
How can I get the instance of the class to call the dispatchEvent for the postTrace function.
1180: Call to a possibly undefined method dispatchEvent.
Code:
package {
import flash.display.*;
import flash.events.*;

I have a base class which is being created via remote_object [RemoteClass alias] from the server.I have other specialized classes that are derived from this baseclass, but serialization with the server always happens with the base class.The base class has meta data that defines what the derived class is, for example
[RemoteClass (alias="com.myco...')]
public Class Base
{

I'm using a library that has a function that returns an instance of some class Engine.
I'd like to tack on some interfaces to Engine, so I subclass it class InterfacedEngine extends Engine implements AwesomeInterface. but when I change the code that uses the classes from this:
var engine:Engine = generateEngine();
to this: var interfacedEngine:InterfacedEngine = generateEngine();
It gives me a runtime error (elision mine):
TypeError: Error #1034: Type Coercion failed: cannot convert ...::Engine@1bc2bf11 to ....InterfacedEngine.
What about AS3 classes am I misunderstanding?
I have to admit I pretty much ran away from Flash when AS2 came along and only used it for animation purposes over the last 5 years.So I'm having a major crash course in AS3 in Flash CS3 and I'm not enjoying it one bit. I'm getting maybe 10mins of finished work per hour as I try to figure out the limits and rules of AS3. Quite often it seems that AS3 simply can't do what I want it to. Anyway: Characterchecks.as is the main class and it loads a bunch of XML into four arrays. The file starts like this:[code]If I trace the value of, say, cc._Categories from the main FLA, it's empty. I'm guessing that the next line of AS in the main FLA doesn't wait for the previously called function to complete? (This may tie in to my next problem)My next step is that I want to display various things based on the data in the array. I have another class, Display.as which will hold all the functions to create the items on display. I thought it would be best for these to be a separate object. I wonder if I'm right?
So I declare an instance of Characterchecks in the main FLA and call it cc, and then run the functions to populate the arrays... Now I create an instance of Display and call it cd. How can I get functions in cd to see the values of the variables in cc? And if the main timeline can't tell that the functions aren't finished filling the arrays, how is cd supposed to know?I might be asking dumb questions, or maybe I'm doing things ***-backwards, I don't know. I'd appreciate any help, I really would. This whole thing has me at the end of my tether... being the most technically advanced person in my circle of co-workers and web design friends means I have no-one to explain why things need to be done a certain way or what the best way is.
i have a main movie. i use a loader to load a "example.swf" file. then i place that file inside a holder movieclip. in example.swf, i have an instance of a class i just wrote. this class has some particular methods. from my main movie, i want to call the methods of the instance of my class i have in example.swf. how can i do that??? i know it's a kind of casting, but none seems to work.
View 1 RepliesFrom my Main class, in the method onBackgrLoad, I am trying to call a couple of public methods (i.e. xmlData, hintergrund & numOfProducts) located in LoadXML. I keep receiving an error message that "loadXML" is undefined. I dont understand why because I clearly defined it in the main class:

I'm creating a little game - The player controls a character that follows the mouse. Pigs run away from the player, and the player has to get them all into a pen. To make the game a little more difficult I'm trying to add an enemy - wolves, that attempt to perform a 'hunt' method every x seconds. This method sends a reference of the wolf instance to Main (my document class) and Main then loops through the pigs on stage to see if there's any nearby. Now as far as I know this works - my problem is I'm unsure how to send the pig instance reference back to the wolf that called the hunt method, so it can then 'target' the pig, and then attempt to pounce on it.
This is my Wolf class:
Code:
package
{
import flash.display.MovieClip;
import flash.events.Event;
[Code].....
If an object, or say... a document class, creates an instance of a class (and stores it as a variable), and it doesn't pass any arguments to the constructor of the class, can that class object, by simply having a function of it called by the parent, tell who sent it that command/request? In other words, can a class object know who called it (such as it's parent) via a (seemingly) anonymous call?
View 1 RepliesDoes creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
View 1 RepliesI just want to ask if is it possible to call a movieclip using the String Class together with it's instance name to use gotoAndPlay() method. I know how to use the instance name and the method but then what if I want to use a string together with the instance name and the gotoAndPlay.
View 1 RepliesQuick question. I have been Googling this all morning, but it's either not there, or else written in a way that doesn't register. I am inclined to believe the latter, as this seems like it should be something completely trivial to me. I made a small Flash file using AS 3.0, and this is the first time I've really been able to stick to the OOP way of doing things and not hack together a mix of stuff from the timeline to get around not having everything work in the classes.
So I'd like to keep it that way, but one thing is eluding me: I can't call a method of an instance of another class (than the one I'm calling from) without resorting to "DocumentClass(root).instanceName.method." Intuition tells me there has to be a better way of doing this (like, without having to reference the document class every time I call another class instance's function; and CERTAINLY without having to use the word "root" - that just seems so Flash 5 to me. Does anybody have a better way of doing this that they can share?

I have a custom class and inside its constructor, I need "x" and "y" arguments passed on. Now when I call the class and create and instance of it, flash should pop up "the code hinting"...(but it doesn't), or am I missing something???
Say i have a movieclip named a_Mc ( ClassA ) I have a sub-movieclip named b_Mc ( ClassB )
CASE 1: Accessing the sub-movieclip b_Mc which is already present inside the a_Mc movieclip
( Since Flash IDE has "Automatic instance naming" OFF )
ClassA mentions the name of b_Mc as => var b_Mc:MovieClip;
NOTE HERE: That the variable name MUST BE same as the name of the instance on stage.
So i can access it as : trace( a_Mc.b_Mc);
[Code]...
How can I call the instance name of a mc? For example in AS2 I would do: this._name How do I do in AS3?
View 3 RepliesI have a library object (SomethingMC) which extends a custom class (Something). Something, in turn, extends MovieClip.If adding SomethingMC to the stage within Flash CS3 IDE, is it possible for it's super class (Something) to assign an instance name from a class constant (Something.THE_CONSTANT)?
package
{
import flash.display.MovieClip;[code].....
The above does not work. It throws Error #2078: The name property of a Timeline-placed object cannot be modified. if the instance is assigned a name in the IDE, and it just doesn't work if no name is assigned in the IDE.
I have a BUNCH of bumpers of four types bounceUp, bounceDown, bounceLeft, bounceRight. during a collision which you hit determines the bounce so they always do the same thing so here's my question.....can i just name every bounceUp instance the same thing and then just add that one instance name to the list the collision detector checks?
i just dont wanna go through and name a hundred each of bounceUp s and bounceDown s individually as the potential for screaming increases proportionally.......
I placed a movie clip instance inside a button, and I want this movie clip to play when the button is released. I'm using this code on the frame containing the button:

Does anyone know if it is possinle to scroll a graphic or a movie instance as well as a text instance in flash. I want to scroll text and images as well. Actually text with imges embedded in it.
View 3 RepliesI am wrapping my brain around OOP in AS2. I am making two posts on two different subjects. My question here is: when should I use local instance variables, and when should I attach new properties to the instance object? (Feel free to correct my terminology.) Let's say I have a class for a scrolling background, which scrolls when I mouse over its edge. I want to put these values somewhere:
1) How wide is the border in which a mouseOver makes it scroll? This is basically a semi-constant I set it up once and keep it the same, unless the user changes it in an options menu to make the border wider or narrower. Call this scrollBorderWidth.
2) How fast is the background scrolling now? I want to track this so I can smoothly change the scroll speed over several frames. This is often changed. Call this scrollSpeed.
It seems I have two ways I can store and access these values and darned if I know which is better practice. METHOD A: Make them local variables in the class, so the scrolling background instance has them as local vars. I set them up thusly:

I have want to tell a movie instance to play from a class:

I am using Flash2004 MX
I thought this would be simple, but it hasn't been.
I have a seris of hidden MCs named star1, star2 etc.
I want them to become visible when I call this function.
star_fn = function() {
starcount++
starshow=("star" + starcount)
starshow._visible=true
}
But it is not working.
I thought maybe it was like converting variable info to a number format, but using a text scenario instead.
configuring this instance movie to play when i click a button, here is my movie structure:
- root movie - container and some external .swf movie
The process is there will be button load at the end of root movie, and calling some external swf movie with number. all the swf will play in a container each swf movie(about 5 animation)
At the end of root movie there is also some loop animation that play at the end of root movie, while we can click the button also.
What i want to do is how can i play the loop movie, start from the middle when i click one of the button.
So what happen will be: - click button = external movie load and the instance name play from frame 100 and loop again.
How would you add a listener to an object inside of a movieclip that is in the library and as not been placed on the stage yet? Or, could you tell it to listen for when it does go on stage if it does come on the stage and when it comes on the stage to add an eventlistener to a movieclip inside of that?
View 3 RepliesIs it possible to call an instance of a movieclip by a variable name?
Say I have several movie-clips on the main timeline and a variable named "disabled". I want to click a button and have be able to tell "disabled" to goto frame 2, where disabled will contain the name of the movie-clip. can I do this?

View 2 RepliesI'm trying to reference an instance through the use of a variable in my call to a prototype. The variable is myVar and contains the instance name to which I want to apply the resizeTo prototype. My syntax is incorrect.
Code:

//disregard this line
this.swapDepths(this._parent.getNextHighestDepth());
//this is calling a prototype named resizeTo
this.resizeTo(150, -100, -100);
//Setting instance name of another movie
myVar = "green";
//Trying to drop that instance name into my next prototype call
this._parent.myVar.resizeTo(100, _parent.old_X, _parent.old_Y);
}
I have 35 textboxes with the names "t1" to "t35". How would I call these names in a for loop? I have tried this with no luck:

I know I'm doing something wrong with the ("t"+i) but I dont know how how to combine a string and number like that.
one of my problem is that how do i call the instance name of a button from my child.swf to my parent.swf
i have four buttons from my child.swf where when i click btn1 it will load superchild.swf but i want to load that superchild.swf to my parent.swf, like instead btn1 calls superchild.swf to load, btn1 will call parent.swf then on parent.swf it will distinguish that btn1 was click from child.swf and it will now load superchild.swf.
