So to be clear, I should be using the parser and the database classes? If
I try the following, I still get an internal error:
arg_data = om.MArgDatabase(self.syntax(), args)
assets = om.MSelectionList()
success = arg_data.getObjects(assets)
When it comes to getting the values of specific flags, I've got the value
with help from examples, doing this:
if arg_data.isFlagSet(kShortCamName):
# We use the '0' to index the flag's first and only parameter.
cam_name = arg_data.flagArgumentString(kShortCamName, 0)
But when I try similarly to use arg_data.commandArgumentString(0), I get an
error. I've gone and done the follow syntax command also:
syntax = om.MSyntax()
syntax.setObjectType(om.MSyntax.kStringObjects, 1)
Is there no way for me to get the list of strings passed to my command?
This problem got me stumped.
