Array of Arrays

In Unity with Javascript I can make an array of arrays, where each of the arrays are of different sizes, but can someone tell me how to access the individual arrays?

var array1 : Array = [1, 2, 3, 4];
var array2 : Array = [5, 6, 7];
var array3 : Array = [8, 9, 10, 11, 12];

var arrayOfArrays : Array = [array1, array2, array3];

When I try the following:

for(var row : Array in arrayOfArrays){ }

I get the error on the for loop:

InvalidCastException: Cannot cast from source type to destination type.

Does someone know how to access the individual arrays in arrayOfArrays?

 

Are you sure you're copying/pasting things correctly? Restated, is there something hidden/different in your actual code as your example works like a charm for me. For example:

Code (csharp):

1. function Start () {
2.  
3.   var array1 : Array = [1, 2, 3, 4];
4.   var array2 : Array = [5, 6, 7];
5.   var array3 : Array = [8, 9, 10, 11, 12];
6.  
7.   var arrayOfArrays : Array = [array1, array2, array3];
8.  
9.   for(var row : Array in arrayOfArrays){
10.     Debug.Log(row[0]);
11.   }
12.  
13. }

If I use that and hit play I see 1, 5, 8 in the Console window as expected.

 

You are right! I am investigating.

 

I had defined the arrays as:

var array1 : Vector3[] = [1, 2, 3, 4];

which produced the cast error. Once I changed the definition to how
I had stated the problem as

var array1 : Array = [1, 2, 3, 4];

then it worked fine as you noticed.

Sometimes just another pair of eyes helps. Thanks!

 

Awesome, I'm glad I could help!
