Tween Machine - PySide6

[Shaikh Anas]

Hello everyone, I am creating a tween machine just for my educational purpose and to understand the logic of it.

I am facing multiple undo issues.

I am attaching two images, where the function is the same, the difference is one, I am running independently to check if is it working fine and 2nd is running through a signal.

So the issue is when a single calls this function it runs perfectly but If I want to undo the changes it will undo every single attribute one by one which takes lots of undo to change.

If I run the script indecently ( screenshot_3.png ) and undo that, it simply takes one undo to change the entire action.

Thanks and Regards,
Shaikh Mohammad Anas

Try calling these before and after the function.

cmds.undoInfo(chunkName="myFunction", openChunk=True)
my_function()
cmds.undoInfo(chunkName="myFunction", closeChunk=True)

This will cause all undoable calls to maya.cmds to be grouped together into a "chunk". It's important to call closeChunk after, as it could otherwise make Maya and undoing unstable. To make it more safe, you could use something like a context manager.

@contextlib.contextmanager
def undo_chunk(name):
    try:
        cmds.undoInfo(chunkName=name, openChunk=True)
        yield
    finally:
        cmds.undoInfo(chunkName=name, closeChunk=True)

with undo_chunk("myFunction"):
   my_function()

That way, even if your function fails or throws an exception, the chunk will still be closed.
