I am in the need of multiple staged WebViews for holding multiple loaded websites at the same time.
I was hoping to manage this by making an array of webviews object, so i could call them later as view[i].
var view:Array=[webview0, webview1, webview2];
for each (var v in view){
var v:StageWebView = new StageWebView();
This gives error: 1086: Syntax error: expecting semicolon before left bracket.
Does someone know how to make an array like that?
You're doing something really weird there in terms of syntax. If you just want an Array of freshly created instances, it goes like that:
// Initialize the array.
var Views:Array = new Array;
// This loop counts 0,1,2.
for (var i:int = 0; i < 3; i++)
{
// Create a new instance.
// Yes, you can omit () with new operator if there are no arguments.
var aView:StageWebView = new StageWebView;
// Assign the new element to your array.
Views[i] = aView;
}
Or, if you need only 3 then you don't need to go algorithmic.
var Views:Array = [new StageWebView, new StageWebView, new StageWebView];
Not on topic but related:
Here is an example of one HTML page hold multiple StageWebViews

I'm using Flash AS3 trying to display random questions from an xml list on stage. When the user clicks an option it should move on to another question but the one they got should be removed from the list so it will not come back.
I have the randomize part okay but can't figure out how to remove the question from the list.
Here is the section I have.
function randomizeQuestion():void {
var numOfQuestions:Number = xmlData.item.length();
var shuffledNumbers:Array = new Array(randomAns.length);
var randomPos:Number = 0;
//Randomizes selected question
currentQuestion = int(Math.random() * numOfQuestions);
//Randomizes answer numbers
for (var i:int = 0; i < shuffledNumbers.length; i++)
{
randomPos = int(Math.random() * randomAns.length);
shuffledNumbers[i] = randomAns.splice(randomPos, 1)[0];
}
randomAns = shuffledNumbers;
correctAns = xmlData.item[currentQuestion].children().(hasOwnProperty("#correct"));
}
Try to get index:
correctAnsIndex = xmlData.item[currentQuestion].children().(hasOwnProperty("#correct")).childIndex();
or if more elements, to get first one:
correctAnsIndex = xmlData.item[currentQuestion].children().(hasOwnProperty("#correct"))[0].childIndex();
then use delete where appropriate, like here:
delete xmlData.item[correctAnsIndex];
I would add another array to your code in which you can store all the questions that are eligible. As a question gets asked, remove it from that array. So you'll have one array of allQuestions and another array of eligibleQuestions. allQuestions can just be a comprehensive list. Then, push all the questions you want to go through into the eligibleQuestions array. As the questions get answered, splice them from the array.
It would be good to also share an example of your XML file that you're loading, but let's use the example below.
<data>
<item>
<question></question>
<option1></option1>
<option2></option2>
</item>
<item>
<question></question>
<option1></option1>
<option2></option2>
</item>
</data>
Based on the code you have, I assume your function is being called each time you want to randomize a question.
Now what you'd want to do is create an array that holds the number of <item> tags you have outside of this function so that you can remove values from it whenever you want.
You can create this var numOfQuestions:Array = new Array(); as a global variable and then initialize it using a loop before you enter the randomizeQuestions() function.
for(var i = 0; i < xmlData['item'].length(); i++)
{
numOfQuestions.push(i);
}
Basically this array will serve as a method of calling a specific item and removing it from the program without altering the actual XML file in any way.
Then whenever you wish to remove an element you use
numOfQuestions.splice(numOfQuestions.indexOf(valueToBeRemoved), 1);
This will search the array for the element you wish to remove and then remove it from the array.
Lastly the randomizeQuestion function has to be modified.
currentQuestion = int(Math.random() * numOfQuestions.length); //since numOfQuestions is now an array instead of a Number
Im really stuck. I have 5 MC´s that are being spliced from one array at a certain time. In that same function I want to push another movieclips into another array. The two arrays holds mc's that represent right or wrong answers. So when one question is being given a correct answer that questions visualisation alters.
This function holds a incrementing variable as I do want the mc's to be pushed by the user and one at the time. The thing is I cant seem to refer them properly.
I´ve tried
pQuestSum = this[pQuest + pQuestNumber];
and
pQuestSum = this[pQuest] + pQuestNumber;
and pretty much everything I´ve imagined would work...but the problem is I havent tried
the right thing.
when I trace pQuestSum (which would be the reference) I get an error saying thats its not a number.
this is one of 5 mc's named from 1-5:
var passedquest1:PassedQuest = new PassedQuest();
this is the vars that i try to to build a reference of
var pQuest = "passedquest";
var pQuestNumber = 1;
var pQuestSum;
var questCorrArray:Array = [];
if(event.target.hitTestObject(questArray[ix])){
removeChild(questArray[ix]);
questArray.splice(ix,1);
pQuestNumber ++;
pQuestSum = this[pQuest] + pQuestNumber;
trace("pQuestSum"); // NaN
questCorrArray.push(pQuestSum);
//trace(questArray.length);
pointsIncreased = false;
questPoints = 0;
}
How do I refer an existing movieclip when the reference consists of both a string and a number? Hope I made myself somewhat clear:)
If you had an instance of an object on your timeline called "passedquest1" (as an example), then you could access it this way:
var myObj = this["passedquest" + 1];
Or,
var pQuest = "passedquest";
var pQuestNumber = 1;
var myObj = this[pQuest+ pQuestNumber.toString()];
When you do this: pQuestSum = this[pQuest] + pQuestNumber;, you are trying add the number to an object (this[pQuest]), unless you have number/int var called "passedquest", this will result in NaN.
I need to have the screenPage var accessible for later calls. I am dynamically creating several pages. The issue is when I call screenPage.startDrag(); then it only drags the last page. How can I add a var in the name or make all the screenPages accessible through code?
Here is code in short:
var screenPage:MovieClip;
for(var p = 1; daTotalPages >= p; p++)
{
screenPage = new theFlagScreen();
}
Can I make screenPage a dynamic var and add like a 1 at the end and then a 2 and so forth with the loop?
Why not use an array ?
var pages:Array = new Array;
for(var p = 1; daTotalPages >= p; p++)
{
var screenPage:MovieClip = new theFlagScreen();
pages.push(screenPage)
}
Now you have an array containing all of your instances.
var myPage:MovieClip = pages[5] as MovieClip;
myPage.startDrag();
Also, the code you have above is creating an instance each time through, but since you then go ahead and create a new one each iteration and assign it to the same variable without storing it or adding it to the display list.... once you create a new one, the last one is marked for garbage collection.
The result is only the LAST instance you created still exists as it's the only one that has a variable that references it.
screenPage is a reference to just ONE thing. In your loop you keep overwriting it as you go and so you end up with it pointing to the very last instance of theFlagScreen... all the others are now lost.
You should follow prototypical's advice and store these instances in an array, that way you don't lose them.
I have a collection of movieclips, I would like to create a clone (a new instance) of a instance everytime I create a new object.
For example
var s:Star = new Star(); // star-shaped movielcip
addChild(s);
// then I want to duplicate an instance of s and add it beside s
For an example like above, it's simple enough to create a new instance with a different name and just add it to the display list. But I have a list of objects I would like to clone as a group...?
Belowed code is very famous for cloning the objects. It's deepest and dynamic.
...
function clone(orjObj:Object):Object {
var copyObj:ByteArray = new ByteArray();
copyObj.writeObject(orjObj);
copyObj.position = 0;
return(copyObj.readObject());
}
var s2:Star = clone(s);
s2.x = s.x + s.width;
s2.y = s.y;
addChild(s2);
moses' solution is correct. What is the purpose of the clone, where you wouldn't need to know the name of the clone to reference it?
One option is you could create an array to store your references in so you don't need to explicitly name them. Using moses' code...
var clones:Array = new Array();
for each (var star:Star in [s, s2, s3, s4, s5]) {
clones.push(clone(star));
}
trace(clones.length); // 5
This will result in an array that holds 5 cloned stars. It takes the least amount of code but it's up to you to make sure you know which star is which afterwards.
so.... eval() out of the question, any idea to do this? I also don't know how to use "this" expression or set() in actionscript 3 ( i seem couldn't find any complete reference on it ), just say through php file a multiple variable (test1, test2, test3,...) sent by "echo", how the flash aplication recieved it? I'm trying not to use xml on mysql to php to flash aplication. Simply how to change a string to a variable ?
example
(in as3-actions frame panel)
function datagridfill(event:MouseEvent):void{
var varfill:URLVariables = new URLVariables();
varfill.tell = "do it";
var filler:URLRequest = new URLRequest();
filler.url = "http://127.0.0.1/flashdbas3/sendin.php";
filler.data = varfill;
var filling:URLLoader = new URLLoader();
filling.dataFormat = URLLoaderDataFormat.VARIABLES;
filling.load(filler);
filling.addEventListener(Event.COMPLETE, datain);
function datain(evt:Event){
var arraygrid:Array = new Array();
testing.text = evt.target.Name2 // worked
// just say i = 1
i=1;
arraygrid.push({Name:this["evt.target.Name"+i],
Test:this.["evt.target.Test"+i]}); // error
//or
arraygrid.push({Name:this["Name"+i],
Test:this.["Test"+i]}); // error too
// eval() noexistent, set() didn't worked on actions frame panel
//?????
}
};
I hope it's very clear.
You could use this[varName] if I understand your question right.
So if varName is a variable containing a string which should be a variables name, you could set and read that variable like this:
this[varName] = "someValue";
trace(this[varName]);
Update:
In your example, you could try: evt.target["Test"+i] instead of Test:this.["evt.target.Test"+i]
If you have a set of strings that you'd like to associate with values, the standard AS3 approach is to use an object as a hash table:
var o = {}
o["test1"] = 7
o["test2"] = "fish"
print(o["test1"])
