Creating a 2D array?

[nutcase88]

Hi im trying to create a 2d array in flash and the fact that im a C++ programmer isnt helping me so im a little lost here.

Ive searched the forums and found something like this


var urls:Array=new Array();
for(i=0;i<3;i++)
{
urls[i] = new Array();
for(k=0;k<3;k++)
{
trace(urls[i][k]);
}
}




However when i put it in the trace returns undefined.


I am looking to create something like a 14 x 14 2D grid where all the variables inside are 0 at the beginning.

I did something like so



myArray = newArray();
for(int i =0; i< 14;i++){
for(int k =0; k< 14;k++){
myArray[i][k] =0;
}
}


But unfortunately it doesnt work.

Please advise, thanks in adv!

The code you found in the forums returns undefined because the values in the array were not initialized. The default value for an array's element is undefined.

Here code for a 14x14 Grid with all values initialized to 0:


var arySize:Number = 14;
var myArray:Array = new Array( arySize );

for( var i:Number = 0; i < arySize; i++ )
{
myArray[i] = new Array( arySize );
for( var k:Number = 0; k < arySize; k++ )
{
myArray[i][k] = 0;
}
}
