I am creating some MovieClips like so:
var AClip:A = new A();
var A2Clip:A2 = new A2();
var A3Clip:A3 = new A3();
I then put the above into an array and am trying to trace out thier "name".
for(var i:int=0;i<theArray.length;i++){
trace(theArray[i].name);
}
This traces
instance99
instance77
instanceN...
What I want to accomplish is the trace is tracing out what I "initialized" them to
AClip
A2Clip
A3Clip
Is there a way to do that?
Thanks
Variable's name is not the same as MovieClip's name. You have to set its name manualy:
var AClip:A = new A();
var A2Clip:A2 = new A2();
var A3Clip:A3 = new A3();
AClip.name = "AClip";
A2Clip.name = "A2Clip";
A3Clip.name = "A3Clip";
Then you can get their name by calling trace(theArray[i].name);

I've 3 mc. I want to call 2 of them on stage randomly in specific locations. I don't know how to call them. I just tried with array. I think array is the best way but still confused.
this's code I tried :
import flash.geom.Point;
var Batumc:batu_mc = new batu_mc(); // creates a instance of the movieclip, i.e, an object
var Batumc1:L = new L();
var Pisangmc:pisang_mc = new pisang_mc();
var Batumc2:MovieClip = new MovieClip();
var Status:int = 0;
button.addEventListener(MouseEvent.CLICK, tombol);
function tombol(e:MouseEvent):void{
//addChild(Batumc);
//addChild(Batumc1);
//addChild(Pisangmc);
var P:Array = [new Point(80.2, 100), new Point(260, 100), new Point(430, 100)];
var M:Array = [Batumc, Batumc1, Pisangmc];
//random benda
var benda:int = Math.random()*M.length;
// Remove the selected benda from its list.
M.splice(benda, 1);
while (M.length){
// Get the last MovieClip and remove it from the list.
Batumc2 = M.pop();
trace(Batumc2);
// Produce a random Point.
var anIndex:int = Math.random() * P.length;
var aPo:Point = P[anIndex];
// Remove the selected Point from its list.
P.splice(anIndex, 1);
// Move the selected MovieClip to the selected Point coordinates.
Batumc2.x = aPo.x;
Batumc2.y = aPo.y;
addChild(Batumc);
addChild(Batumc1);
addChild(Pisangmc);
}
Status = 1;
}
button.addEventListener(Event.ENTER_FRAME, frame);
function frame(e:Event):void{
if(Status == 1 ){
removeChild(Batumc2);
Status = 0;
}
}
when i run this code, sometimes 3 mc appear again
I think the problem is with this line:
M[i] = P.splice(randomPos, 1);
You assign M[i] (array of mc) with value from P (array of points), so M[i] = array with point and not an mc.
If you want to avoid such issues you can use Vectors instead of arrays. Its more efficient and also must contain the type you declared.
Vector class Docs.
To use the vector, instead of:
var P:Array = [...];
var M:Array = [...];
Do:
var P:Vector.<Point> = new <Number>[...];
var M:Vector.<MovieClip> = new <MovieClip>[...];
And the rest is just like arrays (pop, push, slice, ...)
To remove item from M, just splice M, i don't understand why you need to iterate over M.
M.splice(randomPos, 1);
Try getDefinitionByName
var myClass:Class = getDefinitionByName("Class_Name") as Class;
var classInstance:MovieClip = new myClass as MovieClip;
addChild(classInstance);
You just have to determine the specific location in the array for the mc'c, beside that you can get the classes from the library like this;
var locations:Array = [{xpos:100, ypos:12} , {xpos:30, ypos:50} , {xpos:400, ypos:28}, ......];
for(var i:uint=0; i<YOUR_MCS_LENGTH; i++) {
var myClass:Class = getDefinitionByName("Batumc"+i) as Class;
var mc:MovieClip = new myClass as MovieClip;
mc.x = locations[i].xpos;
mc.y = locations[i].ypos;
}
I have followed your advice #Özgün Sandal, but I get this error
ReferenceError: Error #1065: Variable Batumc10 is not defined.
at global/flash.utils::getDefinitionByName()
at nyoba9_fla::MainTimeline/frame1()
this my code :
import flash.utils.getDefinitionByName;
import flash.geom.Point;
var Batumc:batu_mc = new batu_mc(); // creates a instance of the movieclip, i.e, an object
var Batumc1:L = new L();
var Pisangmc:pisang_mc = new pisang_mc();
var P:Array = [new Point(80.2, 100), new Point(260, 100), new Point(430, 100)];
var M:Array = [Batumc, Batumc1, Pisangmc];
for(var i:uint=0; i<M.length; i++) {
var myClass:Class = getDefinitionByName("Batumc1"+i) as Class;
var mc:MovieClip = new myClass as MovieClip;
// Produce a random Point.
var anIndex:int = Math.random() * P.length;
var aPo:Point = P[anIndex];
// Remove the selected Point from its list.
P.splice(anIndex, 1);
mc.x = aPo.x;
mc.y = aPo.y;
}
where's my fault?
var myArray:Array = new Array();
var myMC:MovieClip = new MovieClip();
myMC.myArray = myArray;
trace(myMC.myArray[10]); //Output: undefined
var newMC:MovieClip = new MovieClip();
newMC.myOtherArray = myMC.myArray;
newMC.myOtherArray[10] = [];
newMC.myOtherArray[10][0] = 100;
trace(myMC.myArray[10]); //Output: 100
Why does that happen, and is there any way to avoid it?
EDIT:
Found a function that can clone associative arrays here.
Here is the function (from the above link):
function clone(source:Object):*
{
var myBA:ByteArray = new ByteArray();
myBA.writeObject(source);
myBA.position = 0;
return(myBA.readObject());
}
Does making the function return type "*" mean that it can be any type? or is it something specific to objects/arrays?
It's because you have passed a reference of the original array to the new clip. Arrays, as objects, are not primitives and therefore will always be referenced.
If you would like to clone an array, keeping the original intact, use this method:
var b:Array = a.concat();
b will be a new array. a can modified without changing b.
I'm trying to load 2 images in to my flash file but getting an error - new to this AS3 malarkey any help would be appreciated!
Getting error: 5 1151: A conflict exists with definition request in namespace internal.
var myImage:String = dynamicContent.Profile[0].propImage.Url;
var myImage2:String = dynamicContent.Profile[0].prop2Image.Url;
var myImageLoader:StudioLoader = new StudioLoader();
var request:URLRequest = new URLRequest(enabler.getUrl(myImage));
myImageLoader.load(request);
myImageLoader.x =17;
myImageLoader.y = 0;
var myImageLoader2:StudioLoader = new StudioLoader();
var request:URLRequest = new URLRequest(enabler.getUrl(myImage2));
myImageLoader.load(request);
myImageLoader.x =17;
myImageLoader.y = 0;
if(this.currentFrame == 1) {
addChildAt(myImageLoader, 2);
}
if(this.currentFrame == 2) {
addChildAt(myImageLoader2, 2);
}
It's usually a good idea to move duplicate code into its own function instead of doing copy + paste:
function loadImage(file:String, x:Number, y:Number):StudioLoader{
var myImageLoader:StudioLoader = new StudioLoader();
var request:URLRequest = new URLRequest(file);
myImageLoader.load(request);
myImageLoader.x = x;
myImageLoader.y = y;
return myImageLoader;
}
addChild(loadImage(enabler.getUrl(myImage1),17,0));
addChild(loadImage(enabler.getUrl(myImage2),17,0));
That's not just giving you better structured code but also fixes your duplicate variable definition issue because what's defined locally inside a function stays inside the function.
This might provide some insight:

You can't create a new variable with the same name as an existing one, in your case I'm speaking about your URLRequest request, so to avoid this type of error you can do like this :
var myImageLoader2:StudioLoader = new StudioLoader();
// assing a new URLRequest to an existing var
request = new URLRequest(enabler.getUrl(myImage2));
// here you want use the myImageLoader2, not myImageLoader
myImageLoader2.load(request);
myImageLoader2.x =17;
myImageLoader2.y = 0;
Or :
var myImageLoader2:StudioLoader = new StudioLoader();
// create a new URLRequest var, so the name should be different
var request2:URLRequest = new URLRequest(enabler.getUrl(myImage2));
// here you want use the myImageLoader2, not myImageLoader
myImageLoader2.load(request2);
myImageLoader2.x =17;
myImageLoader2.y = 0;
Additionally, I notice in the second block that you declare myImageLoader2 but you then use the original myImageLoader to do the load request. So even if you do declare a new URLRequest, you wont get both images loaded.
Akmozo's solution has this corrected.
I'm in need of some help. To start with, what I have is an interaction where you fill out 5 text boxes in response to 2 questions. Each of the 5 answers must be filled out as input text and then checked against an array of acceptable responses when the done button is clicked. Also, there are two type differences in the fields. So the first three answer fields belong to a range of acceptable responses in the array: Type A and the next two questions to Type B. It's possible to fill out the correct responses in any order, so long as the typing is correct.
What I can't seem to figure out is why the textFields aren't translating to Strings.

Upon further investigation I've noticed that the loop isn't terminating when it reaches 5. It keeps regurgitating TextFields over and over again with the same variable names and instancing. Because of this, the addChild is dumping input fields one on top of one another in the flash file (which makes editing a text field impossible since your always clicking on a new field positioned directly on top of the one you just edited).
The trace on the loop comes back like this:
inputField1
txt_pos1
inputField2
txt_pos2
inputField3
txt_pos3
inputField4
txt_pos4
inputField5
txt_pos5
inputField1
txt_pos1
inputField2
txt_pos2
inputField3
txt_pos3
inputField4
txt_pos4
inputField5
txt_pos5
inputField1
txt_pos1
inputField2
txt_pos2
and so on.... how can I stop this looping behavior. I've tried if/else breaking and that's not working.
The context of the this keyword changes when you call it from a local function. You can easily verify it if you add trace(this) to your anonymous function. It will trace out [object global]. Two solutions come to mind, store a reference of this in a variable:
var self:MovieClip = this;
for(var f = 1; f<=a_inputType.length; f++){
//...
this[fieldBuilder].addEventListener(TextEvent.TEXT_INPUT, function (){
var stringBuilder = "txtString"+f;
self[stringBuilder] = self[fieldBuilder].text;
});
}
Or declare a new function:
for(var f = 1; f<=a_inputType.length; f++){
//...
this[fieldBuilder].addEventListener(TextEvent.TEXT_INPUT, myFunction);
}
function myFunction(t:TextEvent){
var stringBuilder = "txtString"+f;
this[stringBuilder] = (t.target as TextField).text;
}
i use LocalConnection between two swf in the same page.
What i'm trying to do is to use a String sent from one swf to the other, as variable into my URLRequest...
So i can trace "myVar" into the function chemin, but i didn't find how to use it into URLRequest
thank's for your help
swf that receive the var :
var lc:LocalConnection=new LocalConnection();
lc.client=this;
lc.connect("callBig");
function chemin(myVar:String){
trace(myVar)
}
var chargementXML:URLLoader = new URLLoader();
var fichier:URLRequest = new URLRequest(myVar);
Some references to help you out.
URLRequest.data: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/URLRequest.html?filter_flex=4.1&filter_flashplayer=10.2&filter_air=2.6#data
URLVariables: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/URLVariables.html
So, if you want to pass some variables in your request, you do the following:
Create new URLVariables() object
Assign it's reference to URLRequest.data field.
var fichier:URLRequest = new URLRequest();
var urlVars:URLVariables = new URLVariables();
urlVars["myVarName"] = myVar;
fichier.data = urlVars;
This way your server side app will recieve a variable myVarName with value of myVar.
var lc:LocalConnection=new LocalConnection();
lc.client=this;
lc.connect("callBig");
var receivedVar:String = "";
// somewhere else
function chemin(myVar:String){
receivedVar = myVar;
}
// later
var chargementXML:URLLoader = new URLLoader();
var vars:URLVariables = new URLVariables();
vars.myVar = receivedVar;
chargementXML.data = vars;
var fichier:URLRequest = new URLRequest(myVar);
