ActionScript - General Undo / Redo API?

i've been unsuccessfully attempting to create my own undo/redo classes that work well with any type of possible undo and redo commands.

for example, my simple class works perfectly with undoing/redoing x and y positions of display objects or undoing/redoing values of sliders, etc., but things get dicey when i try to tailor my classes to also work with things like adding and removing items to a list.

is there any well known and well documented solution for general undoing and redoing for actionscript (without Flex)?

Solution

  • There are specific design patters for this kind of stuff in AS3

    Please check the following links: http://lucamezzalira.com/2010/01/12/memento-pattern-in-actionscript-3-undoredo/

    you can also check Command pattern, which is the de-facto standard ,irrespective of the programming language, it would give you the basics.

    Incase you face any issues, please feel free to comment.
