As3 addChild from Array - arrays

I want to add a Child which I loaded into an Array.
I got a Math.random function which returns a Number and should trigger the addChild.
And later I want to splice it into an other Array.
var ground1: MovieClip = new Ground_01;
var ground2: MovieClip = new Ground_02;
var ground3: MovieClip = new Ground_03;
var groundArray: Array = new Array();
var groundMoveArray: Array = new Array();
public function loadGroundArray() {
groundArray.push(ground1);
groundArray.push(ground2);
groundArray.push(ground3);
}
public function randomGround(minNum: Number, maxNum: Number): Number {
minNum = 0;
maxNum = groundArray.length;
return (Math.ceil(Math.random() * (0 + maxNum)));
}

ok, you are almost there... you just need a tweak to your random method to actually add the clip...
var ground1: MovieClip = new Ground_01();
var ground2: MovieClip = new Ground_02();
var ground3: MovieClip = new Ground_03();
var groundArray: Array = new Array();
var groundMoveArray: Array = new Array();
public function loadGroundArray() {
groundArray.push(ground1);
groundArray.push(ground2);
groundArray.push(ground3);
}
public function addRandomGroundToStage(): void {
var randomGroundIndex:int = Math.round(Math.random*(groundArray.length-1));
addChild(groundArray[randomGroundIndex]);
}

Putting an object into an array in as3

So I'm trying to create a row of ten buttons using a for loop that create a new button every time it runs, changing the x value each time. However ever each time a button is created i want it to be put into a specific array so i can refer to a specific button later on. However I'm not sure how to put objects into arrays. Is it possible to do this? This is the code I have so far:
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class backgound extends MovieClip {
var btnx = 30;
var btny= 20;
var row1:Array = [];
public function backgound() {
// constructor code
var continueBtn:Button;
for(var i=0; i < 10; i++)
{
continueBtn = new Button();
continueBtn.x = btnx;
continueBtn.y = 100;
continueBtn.width = 30;
continueBtn.height = 20;
continueBtn.border = true;
continueBtn.visible = true;
continueBtn.label = "Continue";
addChild(continueBtn);
btnx += 30;
}
}
}
}
in your loop:
myArray.push(continueBtn);
or in your loop:
continueBtn =myArray[i]= new Button();
or many other ways.
now you can access your buttons:
myArray[3]// gets the 4th item in your array
I just wonder, is this ALL you want?

Finding objects index in a multidimensional array

Im making an inventory and Im adding stacks but ive hit an issue
below is what I want compared to what works
I just want to find the index of the object I pass through
myArray[0] = [item:object,StackAmmount:int]
var myArray:Array = new Array();
myArray[0] = ["name1",1];
myArray[1] = ["name2",1];
myArray[2] = ["name3",1];
trace("Name" , myArray[0][0]);
//traces "name1"
trace("Stack" , myArray[0][1]);
//traces "1"
trace("Index of Object" , myArray.indexOf("name2"));
//traces -1
// Not Working (NOT FOUND)
//How can I find the index of "item1" or "item2" in the above example
var myOtherArray:Array = new Array();
myOtherArray[0] = "name1";
myOtherArray[1] = "name2";
myOtherArray[2] = "name3";
trace("Name" , myOtherArray[0]);
//traces "name1"
trace("Index of Object" , myOtherArray.indexOf("name2"));
//traces 1
//Working
perhaps there is a better way of dealing with stacks?

I would use a custom class, therefore a 1D vector would be enough. The class would contain the name of the item, and the stack. You could subclass this class to override the maxStack variable of the item, and then the searches would be easier aswell, you could just iterate through the vector and check the name.
public class InventoryItem
{
protected var _name:String;
protected var _stack:int;
protected var _maxStack:int;
public function InventoryItem():void {
}
public function get name():String {
return _name;
}
public function get stack():int {
return _stack;
}
public function set stack(value:int):void {
_stack = value;
}
public function get maxStack():int {
return _maxStack;
}
}
...
public class InventoryWeapon extends InventoryItem
{
public function InventoryWeapon(__name:String, startStack:int) {
_maxStack = 64;
_name = __name;
_stack = startStack;
}
}

Adding movie clips into 2D array

package
{
import flash.events.Event;
import flash.display.MovieClip;
// class
public class GameGrid extends MovieClip
{
private var gameHeight:Number = 600;
private var gameWeight:Number = 800;
private var gridHeight:Number = 50;
private var gridWeight:Number = 50;
private var rowNumber:int = 12;
private var columnNumber:int = 16;
private var backgroundGrid:Array = new Array(12,16);
private var foregroundGrid:Array = new Array(12,16);
function GameGrid(){
}
function addBackGrid(rowN:int,colN:int,mcObject:MovieClip)
{
backgroundGrid[rowN,colN].push(mcObject);
}
function addForeGrid(rowN:int,colN:int,mcObject:MovieClip)
{
foregroundGrid[rowN,colN].push(mcObject);
}
function calculateRowDiff(rowA:int,rowB:int):Number
{
return Math.abs(rowA-rowB);
}
function calculateColDiff(colA:int,colB:int):Number
{
return Math.abs(colA-colB);
}
function calculateCorDiff(colA:int,colB:int,rowA:int,rowB:int):Number
{
return Math.sqrt((calculateRowDiff(rowA,rowB) * calculateRowDiff(rowA,rowB)) + (calculateColDiff(colA,colB) * calculateColDiff(colA,colB)));
}
// add to stage
function paintbackgroundGrid()
{
for (var i:int=0; i<16; i++)
{
for (var j:int=0; j<12; j++)
{
MovieClip(backgroundGrid[i,j]).x = i * 50;
MovieClip(backgroundGrid[i,j]).y = j * 50;
stage.addChild(MovieClip(backgroundGrid[i,j]));
}
}
}
}
}
So what this GameGrid class do is to hold an Array of grids(or tiles which extends MovieCLip) that will be added to the main stage and will call the initializeItem function.
function InitializeItem(e:Event)
{
var gamemap = new GameGrid();
var mc:MovieClip = new MainCharacter();
gamemap.addBackGrid(1,1,mc);
gamemap.paintbackgroundGrid();
//trace("Year: "+gameTime.gameYear+" Month: "+gameTime.gameMonth+" Day: "+gameTime.gameDay+" "+gameTime.gameHour+":"+gameTime.gameMinute+":"+gameTime.gameSecond);
}
The initializeItem should create an instance of gamegrid, and add movieclips to their respective locations(stored using array) and display them.
and this is the error stacktrace:
ReferenceError: Error #1069: Property 1 not found on Number and there is no default value.
at GameGrid/addBackGrid()
The debugger suggest that the error came from the line backgroundGrid[rowN,colN].push(mcObject);
Is there a way I can hold a 2d array movieclips? I'm new to AS3 and it looks very similar to JAVA, what am I missing?
Try this
private var backgroundGrid = [];
function addBackGrid(rowN:int,colN:int,mcObject:MovieClip) {
if (backgroundGrid[rowN] == null) {
backgroundGrid[rowN] = [];
}
backgroundGrid[rowN][colN] = mcObject;
}
In as3, following code means create a array and the array contains two elements, one is 12, and the other is 16.
private var backgroundGrid:Array = new Array(12,16);

How can I convert to int array to dictionary?

Do you have any idea how I can do it?
public override IDictionary<int, DateTime> GetList()
{
var AdList = new Dictionary<int, DateTime>();
AdList = client.GetAdList(loginTicket); //it returns int array.
// I've also tried AdList =client.GetAdList(loginTicket).ToDictionary<int, DateTime>(); it doesn't work..
return AdList;
}
Well, don't have information about how you're going to get dates, or where do you get em from, but i can suggest some code:
public static IDictionary<int, DateTime> GetList()
{
var AdList = new Dictionary<int, DateTime>();
var intArr = GetAdList(); //get your int[] array or List<int>
//if method GetAdList() returns List<int> use this line
intArr.ForEach(a => AdList.Add(a, DateTime.Now));
//otherwise if method returns int[] array use this line
Array.ForEach(intArr, a => AdList.Add(a, DateTime.Now)); //populate dictionary with array elements as keys and DateTime.Now as values
return AdList;
}

ArrayCollection extend error

i extend ArrayCollection class for add push method
package com.cargo.collections
{
import mx.collections.ArrayCollection;
public class DataCollection extends ArrayCollection {
public function DataCollection(source:Array = null) {
super(source);
}
public function push(...parameters):uint {
var i:uint = source.push(parameters);
this.refresh();
return i;
}
}
}
but pushed data is array :/
var test:DataCollection = new DataCollection({id: 1});
test.source.push({id: 2});
test.push({id: 3});
output is
test = Array( {id: 1}, {id: 2}, Array({id: 3}) )
In your example ...parameters creates an array containing all the arguments passed to that function. This should work as expected:
public function push(...parameters):uint {
var i:uint = source.push(parameters[0]);
this.refresh();
return i;
}
Alternatively, if your purpose is to enable the pushing of multiple parameters you can use the Function.apply() method, which will translate a given array into multiple parameters:
public function push(...parameters):uint {
var i:uint = source.push.apply(null,parameters);
this.refresh();
return i;
}
This is the equivalent of saying
var i:uint = source.push(parameters[0],parameters[1],parameters[2]); // etc
