View Full Version : Getting undo labels

06 June 2010, 09:28 AM
Is there anyway to access the label for the last undo entry (or any for that matter)?

Like you want to create a label with your maxscript undo statement, or you want to undo by maxscript to a certain label?

unfortunately there is no easy way to get last undo label (or list of label). It's possible to do it with max SDK, but I don't know the way how to do it with MXS.
but there is some workaround:

with redraw off
global LastUndoLabel
callbacks.addscript #sceneUndo "format \"Undo Label: %\\n\" (LastUndoLabel = callbacks.notificationParam())" id:#undoCheck
max undo
max redo
callbacks.removescripts id:#undoCheck

Thanks, your code gives me another idea for what I want to do.

Incedently, what do disableRefMsgs()enableRefMsgs() actually do? The help file isn't very helpful about this...
