The stage's rect is a special case. Director apparently doesn't let you set
it's coordinates individually. This is probably because Director makes a
separate copy of certain items before it operates on them. For example, you
can't set one point in a vector vertex list, you need to update the entire
vertex list or use a function to do it. For your case, you can use a
temporary rect variable to make the change, such as:
newRect = (the stage).rect
newRect.left = newRect.left + 100
(the stage).rect = newRect
Here is a longer version showing the interim steps:
put (the stage).rect
-- rect(344, 129, 656, 471)
put (the stage).rect
-- rect(244, 129, 656, 471)
newRect = (the stage).rect
put newRect
-- rect(244, 129, 656, 471)
newRect.left = newRect.left + 100
put newRect
-- rect(344, 129, 656, 471)
(the stage).rect = newRect
put (the stage).rect
-- rect(344, 129, 656, 471)
There are also a number of commands, such as "offset" that you can use to
shift a rectangle in a more efficient manner. Refer to Chapter 6 of LiaN
and Chapter 5 of DiaN among others.
