Question

I’m wanting to store four boxes in an array and iterate over all of them in a ‘for’ loop placing each at a different location. I’m using the isometric library As3IsoLib. Here is my code so far.

var BOX1:IsoBox = new IsoBox();
var BOX2:IsoBox = new IsoBox();

var myArray:Array = new Array(BOX1,BOX2);

for (var occr:IsoBox in myArray){

But I’m getting an error at my ‘for’ loop line which is

Description Resource    Path    Location    Type
1067: Implicit coercion of a value of type String to an unrelated type as3isolib.display.primitive:IsoBox.  isometric.as    /main/src   line 51 Flex Problem

Answer 1

This line:

for (var occr:IsoBox in myArray){

Should be:

for each (var occr:IsoBox in myArray){

That will solve the error. This is happening because it is intended to loop over properties of an object, not indexes of an array. So there is a strange type requirement.

The “for each” loop is much better suited to looping over elements of an array.
