Okey, now I understand a bit more about Godot thanks for it, I didn't know how class_name really works, but look this
I set class_name
now it works as you said everywere, thanks
but as you can see in the pictures I did not write Tween. I came to the last 2 arguments and automatically appear a list that includes tween.enum's values, I am sure there is someting on this func to show a specific enum automatically in that argument, only for wirte "," before is needed the enum
this is not happening when I use equip(), then I realise something
but I haven't success
you reserve a vote for your time, I will try to be more specific on my questions, have a good day.
