Processing.py - 类定义上的未知错误 [英] Processing.py - Unknown Error on Class Definition

问题描述

我不知道如何解决这个错误.

I have no idea how to fix this error.

也许在此行之前的某处有一个左括号或引号?

Maybe there's an open parenthesis or quotation mark somewhere before this line?

这段代码有什么问题?

Class Ribbon: # I got an error on this line!
def __init__(self, xpos, ypos, m, g):
    self.x=xpos
    self.y=ypos
    self.mass=m
    self.gravity=g
    ..

def update(self, xpos, ypos):
    ..

def display(self, xpos, ypos):
    ..

推荐答案

这是你的问题:

Class Ribbon (object): 
      def __init__(self, xpos, ypos, m, g):
      self.x=xpos
      self.y=ypos
      self.mass=m
      self.gravity=g

还要记住，其他 def 也必须正确缩进

also remember that other def must be indented properly as well
