Hi All,

I am really struggling with the following. I tried some different versions but the all seem to give the same result:


class SETLIGHT(plugins.ObjectData) :
    def __init__(self) :
    def Message(self, node, type, data) :
        data = node.GetDataInstance()
        if type==c4d.MSG_DESCRIPTION_COMMAND:
            if data['id'][0].id==THE_BUTTON_ID:
                print "Pushed button with command ID", THE_BUTTON_ID
            return True       
if __name__ == "__main__":
    path, file = os.path.split(__file__)
    bmp = bitmaps.BaseBitmap()
    bmp.InitWith(os.path.join(path, "res", "Setlight.png"))
    plugins.RegisterObjectPlugin(id=PLUGIN_ID, str="Lights Controller",
                                description="Setlight", icon=bmp,

Somehow I get the same error in my console:

Traceback(most recent call last) :
TypeError:__getitem__ expected int, not str

Can somebody help me and tell me what I'm doing wrong,
The code above comes form the maxons own sdk manual...

At the beginning of Message() 'data' parameter is overwritten with the line:

data = node.GetDataInstance()

This assigns the object's container to 'data' variable and loose the actual value for the message data to process. Note the previous line doesn't come from the docs code snippet 😉

Also, THE_BUTTON_ID should be an existing variable set to the integer parameter ID of the button to check.

I see the formatting in the code snippet for MSG_DESCRIPTION_COMMAND is broken. It will be fixed.
