我在YouTube上看一个讲座，然后做俄罗斯方块。
但是我得到了这个错误。

我已经实现了block drop。
但之后就不工作了。
我需要你的帮助。我希望你能理解我蹩脚的英语。
尝试为setundobuffer附加任何值，如果setundobuffer中的size值为none则self.undobuffer的值也为none，这就是为什么显示此错误
def setundobuffer(self, size):
"""Set or disable undobuffer.
Argument:
size -- an integer or None
If size is an integer an empty undobuffer of given size is installed.
Size gives the maximum number of turtle-actions that can be undone
by the undo() function.
If size is None, no undobuffer is present.
Example (for a Turtle instance named turtle):
>>> turtle.setundobuffer(42)
"""
if size is None:
self.undobuffer = None
else:
self.undobuffer = Tbuffer(size)
