the code below doesn't resize the arrays:

[monkeycode]

Strict

Function Main:Int()
Local a:String[]=["1","2","3"]
a = a[..6]

Print a.Length

Local b:Int[] = [1,2,3,4]
b = b[..8]
Print b.Length
Return True
End Function

[/monkeycode]

Looks like this never worked (well I went back to v45c).

You can slice to a smaller array or use Resize to increase the array.

I did tried with resizing and it did work.

I just found out also that Resize doesn't work if the array is 0 Length.

Function Main:Int()
	Local a:String[]
	a.Resize(8)
	Print a.Length
	Return True
End Function

Hi,

This is the way slices work in Monkey, you need to use Resize() to 'grow' an array.

> I just found out also that Resize doesn't work if the array is 0 Length.

Resize returns a new array, so you need to go:

a=a.Resize(8)

So in conclusion:
* Use Resize when you want to change the size of an array
* Use Slices when you want to get elements of an array

Both of these operations return a new array and don't effect the one your are performing the operation on.

Correct. If you want to do some more advanced stuff with arrays, check out the Arrays utility class in Diddy.
