[Maya-Python] Multi level undo in one go
Hi, I am changing the values of attributes on multiple objects in the maya scene. Now, if I have to go to the previous state(before the setting of the attributes), it takes lots of Undo. Is thee is a way to undone all the changes at once. Also, if I run the setting of the attributes from a function or procedure, all the changes get undone at once. But, I am not able to attain the same functionality from my script. Thanks. -- You received this message because you are subscribed to the Google Groups Python Programming for Autodesk Maya group.

Hi, What you can try is an open and close chunk of your undo queue. ## Opens a new undo chunk cmds.undoInfo(openChunk = True) ## Closes the chunk again cmds.undoInfo(closeChunk = True) Keep in mind though that if you have an error in your script halfway you might lose your entire undo stack. Maybe make a button that closes the undo chunk. so you can always preserve your undo stack. if you really want to make your life easy make a decorator function out of it. That way you can use it for every function you want to wrap in one undo call. Hope that helps. 2013/1/23 blindtresddd blindtres...@gmail.com Blue pencil plug? Anyone?

Re: [Maya-Python] Multi level undo in one go
The decorator is a nice suggestion. You could also create a context using contextlib (http://docs.python.org/2/library/contextlib.html) so that you can wrap sections of code in something that first starts the chunk and then closes it regardless of an exception: with undoable(): func1() # maybe calls 10 other things func2() # ah, raises an exception!
