Can i use Return to get a List or an Array? Can it only be used with 0's and 1's?

Yes you can, you can get a method or a function returning anything you like:

Ints:

Method GetX:Int()
   Local i:Int = 5
   Return i
End

Strings:

Method GetName:String()
   Local i:String = "Steve"
   Return i
End

Lists:

Method GetList:List<Spark>()
   Local i:=New List<Spark>
   Return i
End

User Object:

Method GetList:Player()
   Local player:Player =New Player
   Return player
End

Ok thanks. I think i am getting the syntax wrong on the receiving end.

If i try to say


Field ReceivingIntList:IntList = New IntList
ReceivingIntList = GetIntList()

Method GetIntList()
Local a:IntList = New IntList
a.Addlast(1)
Return a
end

This is basicly what i am doing, but i get "Cannot convert IntList to Int" error.

Method GetIntList : IntList()
Local a:IntList = New IntList
a.Addlast(1)
Return a
end

try the above, you need to tell the method that you intend to return a list.

To help these kind of errors, put "Strict" at the top of your code. It will force you to put a return type in every method/function, if there isnt a return value you need to use "Void".

Strict

Function Main:Int()
   New Game()
   Return 0
End

Class Game
   Field x:Float

   Method New()
      x = 10.5
   End

   Method GetX:Float()
      Return x
   End

   Method MovePlayer:Void()
      x += 10
   End
End
