I've dynamically created 3 buttons, that when clicked shows me the "id" of that button.But when I try to do something specifically to an individual button, I can't seem to target it by it's instance name. How can I apply an instance name to each button during the loop?
Code:
for (var i:int = 0; i < 3; i++) {
var myMovieClip:MovieClip = new MovieClip();

Does 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 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:
[Code]....
I have a general / somewhat newbie question. Is it better practice to call a function from another class like so:

Does one way free up more memory or enhance performance?
I have a base class I've used on 6 different MC's. Then when I use these MC's my function runs an if statement to check which one to add.
if(id=design) var obj = new design();
if(id=team) var obj = new team();
I want to make it a bit more dynamic and use the id:String to evaluate which new instance to create.
ActionScript Code:
public function loadChapter(id:String):void {
var obj = new instance_of( id )();
}
I have a bunch of text boxes which are acting as labels on a diagram.The idea is all the labels are jumbled up to start with, and the user has to drag the labels to the correct place.So far, I have the labels, and they are dragable, but I want to be able to lock the label onto a specific area (I've called them crashzones) so that when the user drags the label onto the correct area, the label snaps into place.The 'crashzones' instance names, are indentical to the label instance names, with the exception that the 'crashzones' instance names have the letter 'z' at the begining.
On the dragStart event, something (maybe a string) would hold the instance name of the current label and add the letter 'z' to the beggining, so something like ... crashzone = "z" + label1;As there is an instance with the name "zlabel1", when the dragstop event starts, it'll do a 'hittestobject' on the instance "zlabel1".
I'm not entirely sure how to go about this.I've tried creating a string to hold the 'crashzone' name, but the hittestobject event doesnt work with strings i.e: hitTestObject(stringname);I've also tried with Sprite, but as the sprite technically already exists and has a name, I can't give the sprite any properties.
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'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;

how do you do this...if (you rollover instance 'imgsmall' ) then
display visible instance 'imglarge' then
rollout (instance 'imgsmall') then do not display 'imglarge'
I have a whole bunch of movie clips within a single movie clip. I want to trace exactly which instance-within-instance was selected when the user clicks on the outer movie clip. In other words I need Flash to return the instance name of the Movie Clip I just clicked on.
View 4 RepliesSay 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);

You can upcast or downcast an instance (to a superclass or subclass) using this syntax:
var i:MyClass = MyClass(instance);
But what does the as keyword do?
var i:MyClass = (instance as MyClass);
Quick 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've got 2 FLVplayback components;
one with the instance name "vidPlayer" the other with instance name "myPlayer"
I want to link them together so that when myPlayer is paused - then vidPlayer pauses too.
Then when myPlayer plays again, vid Player also plays. Also vidPlayer needs to be told to loop the video; but myPlayer doesn't loop I had a crack at it but keep getting errors as I've only been using flash for just over a week. The script i've already done is pretty much irrelevant as its proper crap
I am trying to add a LOAD EXTERNAL MOVIE CLIP behaviour to a button sitting in a .FLA called SERVICESMENU. I want to load a .swf titled MULTIMEDIA.SWF into an instance of an empty symbol called PAGE LOADER on a different .FLA called MAIN.FLA.

View 1 RepliesI have a object which I have called crosshair. I need to put the crosshair at the place where the mouse is. I know how to do that with hiding the crosshair until it's needed, but I need to make a crosshair for each character (this will be a game where you get to control many units at once), so I will need it for both spawning these units and for spawning the crosshair.
Also, I need to make a line between the crosshair and where the character is at the time. Is there any easy way to do this in actionscript?
i'm using a componet that make a cool effect, but it won't let me add more function to the buttons, like loading external swf's.i have 3 buttons:
-button1 (with instance name 'button1' that calls button1.swf)
-button2 (with instance name 'button2' that calls button2.swf)
-button3 (with instance name 'button3' that calls button3.swf)
and the component get the button target with a function +/- like this:
this.btnTarget = this._parent[this._targetInstanceName]

#initclip
moveBtnClass = function () {
this.init();

I'm trying to improve a tracer/debugger function, but I'm stuck with a detail.
I want to be able to trace/output a given variable value AND it's own name. [code]...
I have been making things like games and tutorials in Flash, and have been making buttons (like arrows) and instance naming them the same name. Whenever I do this, however, even though an error doesn't come up in the Compiler Errors/ Output tab, it does some pretty weird things, like skipping frames by 2's. But these weird errors only occur when I do that. I think it's a coincidence, but now I'm not sure. Should I stop? Bascially, should I always have different Instance Names?
