I know this sounds silly, but it seems like I can't get notify messages any longer despite the fact that my Python Tag is linked to the null. The first example works, the second, which is practically a blank project, does not. Please have a look at the console to see the user data button in action. What am I missing?
Thanks for your time,
User Data Button test.c4d
User Data Button - No Notify Messages.c4d
I figured it out.
The missing piece is a listener that's supposed to be added in main(), something like:
obj = op.GetObject()
bc = c4d.BaseContainer()
obj.AddEventNotification(op, c4d.NOTIFY_EVENT_MESSAGE, 0, bc)
The reason why this was not so obvious earlier today is that I read somewhere that there was no need for adding listeners in main(), that I would be adding unnecessary tasks. This is probably my fault, I may have misinterpreted or assumed things from a different context.
But, to my defense, I must say that the code that works has no listeners in it. Have a look!
Well, this is where it gets tricky: the listener code had been there indeed, but I had erased it after a few iterations(because I thought it was overkill).
This means that the listener is still working despite the fact that I had it erased from the Python Tag code, in other words, it's garbage.
I hope this helps other users as well as the Maxon team(you guys rule!)
