In Ren'Pys python section I've tried to do following:
python:
class test_class0():
def __init__(self, **kwargs):
self.test0 = kwargs['test0']
class test_class1(test_class0):
def __init__(self, **kwargs):
super().__init__(**kwargs)
self.test1 = kwargs['test1']
test_obj0 = test_class0(test0 = 0)
test_obj1 = test_class1(test1 = 1, test0 = 0)
This works fine for standalone Python, but with Ren'Py I've got following traceback:
While running game code:
File "script.rpy", line 62, in script
python:
File "script.rpy", line 75, in <module>
test_obj1 = test_class1(test1 = 1, test0 = 0)
File "script.rpy", line 71, in __init__
super().__init__(**kwargs)
TypeError: super() takes at least 1 argument (0 given)
This error occurs because Ren'Py apparently uses Python 2, where super
worked differently than in Python 3 (see Python extending with - using super() Python 3 vs Python 2).
It seems that support for Python 3 was added in Ren'Py version 8.0.0, which was released on June 26, 2022, so I suggest upgrading.
