Challenging!
I would want to set the evaluation mode to be ‘off’ if the previous action
is/ belongs to my custom tool.
If you want to perform a specific command on undo, you could implement your
tool as a Maya Command.
from maya import cmdsimport myTool
myTool.install()
cmds.myTool()# "Doing!"# (press z)# "Undoing.."
*myTool.py*
from maya import cmdsfrom maya.api import OpenMaya as om
class MyTool(om.MPxCommand):
def doIt(self, args):
print("Doing!")
def undoIt(self):
print("Undoing..")
def redoIt(self):
print("Redoing!")
def isUndoable(self):
# Without this, the above undoIt and redoIt will not be called
return True
maya_useNewAPI = True
def initializePlugin(plugin):
om.MFnPlugin(plugin).registerCommand("myTool", MyTool)
def uninitializePlugin(plugin):
om.MFnPlugin(plugin).deregisterCommand("myTool")
def install():
# Load command on `import myTool`
cmds.loadPlugin(__file__)
If you put e.g. cmds.evaluationManager(mode="off") in the undoIt method,
then whenever you undo this particular command, it’ll turn off (which is
another word for DG) the evaluation manager.
