When i try to compile this code i get a "Array index out of range" error message but i can't find any errors in the code... it's driving me crazy.


Function Main:Int () 
	
	Local numbers:Int[] = [0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20]
	
	
	For Local i:Int = 0 Until numbers.Length() 
		Print(numbers[i])
	End 

	Return 0	
		
End Function

That's strange... did you change anything else or the build target (release and debug)?

Anyway if you didnt know you can also access the values of an array using EachIn:

	Local numbers:Int[] = [0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20]
	
For Local i:Int = Eachin numbers
	Print(i)
End

I don't know if it still happens, but there used to be a glitch where you could compile but a previous version would run (I think only HTML5 and/or Flash). So you could fix a bug and not see the fix.

Or it might have been Just One Of Those Things.

shouldnt it be

For Local i:Int = 0 Until numbers.Length() - 1

?
As in your example array length is 11, but arrays start with index 0, so your doing a for loop from 0 to 11 ie 12 indexes.

Until goes from start to max -1
To goes from start to max
