Question

I have 2 multidimensional array, both of the same size. I need to copy the content from one to another. Is there a better way for doing that than this one??

for(var i : int = 0; i < cols; i++) {
     for(var j : int = 0; j < rows; j++) {
          myArr1[i][j] = myArr2[i][j];
      }
}

EDIT: Im using JS.

System.Array.Copy (myArr1, myArr2, myArr1.GetLength(0)*myArr1.GetLength(1));

BCE0023: No appropriate version of 'System.Array.Copy' for the argument list '(Array, Array, System.Object)' was found.

Im using JS. I forgot to mention :)

So am I (it's obvious from your code). I guess you're not actually using multidimensional arrays, instead you are using Arrays of Arrays. Which is bad. ;) Use multidimensional arrays instead.

Why is it bad to use arrays of arrays?

There are some cases where it is useful...
