Confusing behaviour with properties

[peterigzParticipant]

I’m not sure if this is intended or not but the following code illustrates what I mean. It involves setting the value of a field using a property, by using values of the property itself. I won’t be doing this anyway as I’m switching to returning a new struct rather then changing it’s values but nevertheless thought I’d see if this is meant to be or not as it seems unintuitive:

Struct Test Field _vector:Vec2 Property Vector:Vec2() Return _vector Setter (v:Vec2) _vector = v End End Struct Vec2 Field x:Float Field y:Float Method New(x:Float, y:Float) Self.x = x Self.y = y End Method SetPosition(x:Float, y:Float) Self.x = x Self.y = y End Method toString:String() Return x + ", " + y End End Function Main() Local test:=New Test test.Vector = New Vec2(1,1) Print "Create vector to:" Print test.Vector.toString() test.Vector.SetPosition(-test.Vector.x, -test.Vector.y) Print "Reverse vector property, should be -1, -1..." Print test.Vector.toString() Print "Now try with field directly:" test._vector.SetPosition(-test.Vector.x, -test.Vector.y) Print "Reverse vector property, works as I'd expect..." Print test.Vector.toString() End
