I want to print class name such as Insect,Insect2 from an array. but I don't do this. I am also try using insects[i].name. But the output will shown only object. But I want to show Insect,Insect2. How can I solve this.
private var insects:Array;
var ins:MovieClip;
var ins:MovieClip;
//trace(Math.random());
if(Math.random()>0.5){
ins = new Insect();
ins.speedY = insectSpeed;
ins.score = -10;
}else{
ins = new Insect2();
ins.speedY = insect2Speed;
ins.score = 1;
}
game_mc.addChild(ins);
insects.push(ins);
for(var i:int=0;i<insects.length;i++){
trace(insects[i].name);
trace(insects[i]);
}
Output---1
I want to print only Insect or Insect2 name. How can I do that?
There's a method to obtain a class name from the object or class reference.
import flash.utils.getQualifiedClassName;
for (var i:int = 0; i < insects.length; i++)
{
trace(getQualifiedClassName(insects[i]));
}

It shows an error when written this script has a package that cannot be nested how can I resolve the problem.
If not can anyone give me a new code so that I can try to make the new file?
I have this file in previous stack AS3 Bingo ticket generator
but i couldnt understan how to use it.

TL;DR: "Main" in the class definition may have to be changed conflict of already existing name. Extends sprite may need to be changed to extends movieclip. RandomPlus either needs an import you don't have or needs to be made into a symbol and exported to Actionscript.
Ok, so a few things:
If you are really putting the code into the stage code area, then you can't use the private identifier.
Unless RandomPlus is an object that you have defined in the stage it is probably either not a method you can use or you don't have the right imports for it. Look up what imports you need for RandomPlus or if it is an object defined in the stage then you may need to turn it into a symbol or if you have already export it to flash ActionScript I think. To do this you have to check the checkbox in the middle of the symbol creation page. It will always give you the error when you do this, but don't worry it is fine that way.
Third thing is that I never extend sprite in the class definition, I always do extends movieclip(not sure of the capitalization, but you can look that up). You may also be running into an error from using "Main" as the name because it may be a conflict with a name or method already defined in flash in general.
One last thing is for the variable declaration(mostly just for making the code more readable). While it is good to not declare variables as global when you don't have to, I tend to like having most of the variables up at the top, because I like to be able to see most of the declarations in one space. It's not necessary, really just a personal opinion, and I know a lot of experienced coders will say to do what you did, but if you want to use the arrays in multiple functions then sometimes it is easier to just declare them globally rather than having to pass a million things in the function call and then having to figure out later where all the variable declarations are called and where they are being passed as arguments. Again it's more of a coder's choice, but you can also just do whatever you feel more comfortable with rather than just following the already laid out rules by people who have more experience coding.
Another optional fix to the organization might be to name variables something meaningful so as to not forget what they are all doing. I am bad at naming as well, but I think it's really better to name them something better than just a single letter or two.
Another thing that can help is placing trace(code or "text"); in different places to see what's going wrong once you have the compiler happy.
Please can you help me out I am new to as3 and I am trying to create a shuffled deck using the Fisher-Yates Algorithm. When I run the code with ctrl-enter it compiles with no errors but when I try to output it with trace(); it comes back with:
Scene 1, Layer 'actions', Frame 1, Line 6 1120: Access of undefined property shuffledArray.
Like I said I am new to this and it will be me doing something very stupid but all the same i'm stuck.
Here is the code
package src.CardDeck
{
public class CardDeck
{
public var allCards:Array = [];
public var cardNames:Array;
public var cardValues:Array;
public var gameType:String;
public var drawnCards:uint = 0;
public function CardDeck(game:String)
{
gameType = game;
cardNames = ["Ace","Two","Three",
"Four","Five","Six",
"Seven","Eight","Nine",
"Ten","Jack","Queen","King"];
if(gameType == "texasholdem")
{
cardValues = [1,2,3,4,5,6,7,8,9,10,10,10,10];
}
makeSuit("Spade");
makeSuit("Heart");
makeSuit("Diamond");
makeSuit("Club");
}
function makeSuit(suitString:String):void
{
var card:Object;
for(var i:uint = 0; i < cardNames.length; i++)
{
card = {};
card.cardType = suitString;
card.cardName = cardNames[i];
card.cardValue = cardValues[i];
card.isDrawn = false;
allCards.push(card);
}
}
public function shuffleFisherYates():Array
{
var shuffledArray:Array = [];
var randomCardIndex: int;
do
{
randomCardIndex = Math.floor(Math.random()* allCards.length);
shuffledArray.push(allCards[randomCardIndex]); // add to mix
allCards.splice(randomCardIndex,1); // remove from deck
}while(allCards.length); // Meaning while allCards.length != 0
return shuffledArray;
}
}
}
and here is the .fla actions layer
import src.CardDeck.CardDeck;
var deck:CardDeck = new CardDeck("texasholdem");
trace(shuffledArray);
I know its probably something silly but i'm struggling.
Thanks in advance!
Paul
var deck:CardDeck = new CardDeck("texasholdem");
trace(shuffledArray);
This doesn't work because shuffledArray isn't defined there.
Try :
var deck:CardDeck = new CardDeck("texasholdem");
var array:Array = deck.shuffleFisherYates();
for(var i:int=0; i<array.length; i++)
{
trace(array[i].cardName);
trace(array[i].cardType);
trace(array[i].cardValue);
trace(array[i].isDrawn);
}
"shuffledArray" is a property inside of your CardDeck object. To access public methods and properties within it, you need to use the dot syntax:
trace(deck.shuffleFisherYates());
However, depending on what you are doing, you may not need to really be accessing the array directly, if your CardDeck object is meant to control the entire deck.
I am trying to create a vector from unknown class, but it fails, any ideas about how to do it?
This is what i tried:
var vector:Vector = new Vector(); // throw exception
function base():void{
var vector:Vector.<String> = createVector(String);// throw classCastException
}
function createVector(cls:Class):*{
var array:Array = new Array();
for(var i:int = 0; i < 10; i++){
var element:cls = new cls();
array.push(element);
}
return Vector(array);
}
Vector is expecting a parameter type so you can't do this like you want, but using getQualifiedClassName to get class info you can construct a string that will enable you to call the Vector. constructor using getDefinitionByName :
Ex.
// get class parameter name
var className:String=getQualifiedClassName(String);
// get the Vector class object for the given class
var o:Object=getDefinitionByName("__AS3__.vec::Vector<"+className+">");
// call the constructor
var v:*=o.prototype.constructor(["hello", "world"]);
So your function can be written as:
public function createVector(cls:Class):*{
var cn:String = getQualifiedClassName(cls);
var o:Object = getDefinitionByName("__AS3__.vec::Vector.<"+cn+">");
var array:Array = [];
for(var i:int = 0; i < 10; i++){
var element:* = new cls();
array.push(element);
}
return o.prototype.constructor(array);
}

Based on #Patrick answer I found a working solution.
Check it out:
function createVector(cls:Class):*{
var className:String = getQualifiedClassName(cls);
var vectorClass:Class = getDefinitionByName("__AS3__.vec::Vector.<"+className+">") as Class;
var vector:* = new vectorClass(10);
for(var i:int = 0; i < 10; i++){
var element:MyClass = new cls(); // may be Object or Object extends cls
vector[i] = element;
}
return vector;
}
Class ShootGame implements IGame
{
}
//ShootGame Vector
var shootGames:Vector.<ShootGame> = new Vector.<ShootGame>();
for(i=0;i<20;i++)
{
shootGames.push(new ShootGame());
}
var igames:Vector.<IGame> = //What is the Simplest method to convert ShootGame to IGame Vector
//I am doing like
igames = new Vector.<IGame>();
for(i=0;i < shootGames.length;i++)
{
igames.push(shootGames[i]);
}
There is a more convenient way to do that.
var igames:Vector.<IGame> = Vector.<IGame>(shootGames);
Notice that when you use "Vector.< IGame >(shootgames)" you are not making a typecast, instead you are creating a new Vector instance and populating it with the content of the "shootGames" Vector.
For more detailed information, go here.
Sample code:
var shootGames:Vector.<ShootGame> = new Vector.<ShootGame>();
for (var i:int = 0; i < 20; i++) {
shootGames.push(new ShootGame());
}
var igames:Vector.<IGame> = Vector.<IGame>(shootGames);
trace("shootGames.length", shootGames.length); //20
trace("igames.length", igames.length); //20
I need to dynamically generate a object like this
{type:"typeA",size28:0,size29:0,size30:0 etc...}
I get the sizes from a xml file as an array and I need to insert it like this
{type:"typeA",here the generated size array but as the object properties}
How can I do this?
Thanks in advance.
I assume that the length of the array is variable:
var obj : Object = {type:"typeA"}
for (var i : int = 0; i < generatedArray.length; i++) {
obj['size'+(28+i)] = generatedArray[i];
}
var xmlData:XML = <obj>
<contents>size28:5,size29:3,size30:9</contents>
</obj>;
var obj:Object = new Object();
var xmlObjArray:Array = xmlData.contents.split(",");
for (var i in xmlObjArray)
{
var objProp:Array = xmlObjArray[i].split(":");
obj[objProp[0]] = objProp[1];
}
trace (obj.size29);
