Commands for Omniverse Kit.
omni.kit.commands module is used to register and execute Commands. It is built on top of omni.kit.undo module to enable undo/redo operations with Commands.
Command is any class with do() method and optionally undo() method. If Command has undo() method it is put on the undo stack when executed.
It must be inherited from Command class for type checking.
Example of creating your command, registering it, passing arguments and undoing.
class MyOrange(omni.kit.commands.Command):
def __init__(self, bar: list):
self._bar = bar
def do(self):
self._bar.append('orange')
def undo(self):
del self._bar[-1]
>>> import omni.kit.commands
>>> omni.kit.commands.register(MyOrangeCommand)
>>> my_list = []
>>> omni.kit.commands.execute("MyOrange", bar=my_list)
>>> my_list
['orange']
>>> import omni.kit.undo
>>> omni.kit.undo.undo()
>>> my_list
[]
>>> omni.kit.undo.redo()
