I am trying to addChild to Movie Clip by its instance name but can't do it.
Here is what I get when I trace my loader.name
MC_0
MC_1
MC_2
MC_3
Now I want to add a child to MC_2 but can't do it.
I tried
this[MC_2].addChild(player)
MC_2.addChild(player)
InfoMcHolder_mc[MC_2].addChild(player)
[Code]....
i have a set of images with incrementing names image1, image2, image3 etc and i have a series of empty movie clips on the stage also with incrementing names mc1, mc2, mc3, etc
i wanted to use this:
mc_empty.addChild(my_loader);
to display a series of images into the series of movieclips on stage my_loader is an incrementing variable, and that works fine with the .addChild however, when specifying what addChild is loading content into, it doesnt seem to favour variables as names, it only seems to like real instance names thought i could use
getChildByName("mc_empty"+num)
like this:
getChildByName("mc_empty"+num).addChild(my_loader) ;
but that doesnt seem to work with .addChild either
I need to know when an element is added to the stage (using main document class). So i use :
Code:
public override function addChild(__child:DisplayObject):DisplayObject{
super.addChild(__child);
trace("child added");
return __child;
}
Which works fine. I also use a static class, to which i pass the stage using :
Code:
public static function setStage(__stage:Stage):void{
_stage = __stage;
}
But if i add to the stage (_stage) a MovieClip from the static class, my "real" stage doesn't seem to get that something was added. So i guess _stage !== stage.
So why is this happening, why is _stage not getting the methods of stage ?
I'm trying to have a class file which can add objects to the stage via addChild; however, when I call addChild from within the class file, I get the error "1180: Call to a possibly undefined method addChild." I've tried importing flash.display.* and that doesn't fix the problem. Does the class file have to extend Sprite or MovieClip to be able to add objects to the stage?
View 8 RepliesI have downloaded Box2d ([URL]) and created a project that looks like this: [URL]. catalyst is the green cube and it has the base class "shapes.box", it is inside "world" which has the base class "wck.World". What i want to do is to add another "catalyst" from the library inside "world" when i click on add_btn. I tried to accomplish this by this code:
[Code]...
Symbol 'buttons', Layer 'Actions', Frame 1, Line 41061: Call to a possibly undefined method addChild through a reference with static type Class.
I have the followings:
_p:Player (which is a MC)
a1:Animation1 (which is a MC)
_p.addChild(a1); //doesn't display anything
_p.stage.addChild(a1); //displays a1
Why won't the MC display a child without using his stage?
I'm trying to resolve an issue that reared it's ugly head yesterday.Frame one of main timeline I have the following code:
Code:
import flash.display.MovieClip;
import flash.events.MouseEvent;
[code]....
The newMC doesn't show up.If I add 'parent.' in front of the addChild then it appears.mc_LibItem has a base class of "flash.display.MovieClip" and is exporting for ActionScript and on frame one.For grins I created a new .fla and began messing around with the same addChild idea and it worked.
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 Repliessomewhat understood the basics of adding and removing children, however, I am facing another problem. After using the removeChild Function, I can't seem to add another child.For example:
ActionScript Code:
var attachedMC = new (getDefinitionByName("Content1") as Class)()
Page.addChild(attachedMC);
[code].....
I have a main "shell" swf which, by clicking several buttons, will load/unload various external swfs into a Placeholder_mc which resides on the main timeline in Shell.swf In the documentation and tutorials I've seen a couple different methods, and I'm not sure I quite understand the difference, or at least the reason you would use one over the other...In the 1st method, you can just add the Loader object using the addChild() method:
Code:
var myLoader:Loader = new Loader();
var myURLRequest:URLRequest = new URLRequest("ExternalFileA.swf");
myLoader.load(myURLRequest);
Placeholder_mc.addChild(myLoader);
This will apparently add myLoader to the display list once it has completely loaded.The 2nd method, you supposedly can add the Loader.content; however, it appears you can only do this once the content has completed loading, so you need to incorporate an event handler with the contentLoaderInfo object:
Code:
var myLoader:Loader = new Loader();
var myURLRequest:URLRequest = new URLRequest("ExternalFileA.swf");
myLoader.load(myURLRequest);
[code]....
What are the pros/cons of adding the entire Loader object, as opposed to the Loader.content and vice versa?
I 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:
function playMovie(event:MouseEvent)
{
this.theButton.theMC.gotoAndPlay(3);

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:
[Code]...
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;
[Code].....
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);

What I have is a function that occurs every second. Every time this function is called, it will add two movie clips from the library onto the screen. I am wondering if there will be a problem if my function keeps on continuously adding children to my scene?
Code:
import fl.transitions.Tween;
import fl.transitions.easing.*;[code].............
Im wondering if its possible to arrange movieclips with addchild in such a way like this?:[code]mc_1 and mc_2 is in my case a forward and back button (obviously these have to be on top all the time).. mc_3 - 6 is images rotating.
View 2 RepliesI'm new to programming in general, so not only are the basic concepts new to me but OOP and all of the various underlying rules are keeping me very frustrated in this learning process..I've reached a point that I'm simply stuck and can't find the solution through trial and error, and perhaps am not grasping how addChild works. traces just fine, but then when I try to run addChild I get "error 1023: stack overflow occurred: at Bullet$iinit()".Ignore the commented out lines, they're just for some testing and some trial and error).
//Bullet Class

I have a movie clip that I add Bitmaps by using addChild(). I was wonding how would I go about displaying the next image that I added because as of now it is stuck on the first image.
