Command line parameter problem

Hi,

We are trying to develop a (Tag) plugin to switch camera's from the command line. We thought we had it working since it works when we open a c4d file in the GUI and it switches to the right camera, but when we render on the render farm (command line / nogui) it doesn't work. It gives us:

File "'CommandLine.pyp'", line 31, in Execute
AttributeError: 'module' object has no attribute 'argv'

In the log

This is the code:

import c4d
import os
import sys
import getopt

print 'Number of arguments:', len(sys.argv), 'arguments.'
        print 'Argument List:', str(sys.argv)
        try:
            opts, args = getopt.getopt(sys.argv,"c:s:",["camera=","setting="])
        except getopt.GetoptError as err:
            print "Error: Unknown command line options!"
            print "We only support -c|--camera= -s|--setting="
            return False

        camera = ''
        setting = ''
        for opt, arg in opts:
            if opt in ("-c", "--camera") :
                camera = arg
                print "camera = ", camera
            elif opt in ("-s", "--setting") :
                setting = arg
                print "setting = ", setting
        commandRead = 1

        adraw = doc.GetActiveBaseDraw()
        roots = doc.GetObjects()

        cameraFound = 0
        for obj in roots:
            if obj.GetName() == camera:
                adraw.SetSceneCamera(obj)
                cameraFound = 1
        c4d.EventAdd()

        if cameraFound == 1:
            camname = adraw.GetSceneCamera(doc).GetName()
            print "Camera :", camname, "selected"
        else:
            print "Camera not Found!"

Is getopt not availble during load? Of are we missing something here? I hope someone can help. We need this for a customer job.

Hi,

To get the Cinema 4D command line arguments implement PluginMessage() and filter the C4DPL_COMMANDLINEARGS message. In this message sys.argv holds the command line arguments.
You can then store them using a global variable to be used afterwards in your Tag's Execute().

See Command Line Arguments in the Python documentation for a code snippet and more information.

Thank you very much I'm going to try that.
