RE: FLASH: tracking _x of object w/in MC (newbie)

[Paul Willoughby]

That 'localtoglobal' thing seems a bit overly complicated to me, as you have

to define the point you want to convert as a new object. Not being too au

fait with the old OOP I can't make head nor tail of it :-(

An alternative is to use the old F4 workaround of adding the x/y positions

together of the parent and its child, for example:


realBoxX = _root.master_mc._x + _root.master_mc.box_mc._x
