Pygame 入门实战之简单的flappybird小游戏

这是我大二上学期学python写的课程设计一个小鸟管道小游戏，写的很简单，拿出来分享下，有兴趣的可以进一步优化。
代码如下：

import pygame,sys
import random

class Bird():
    """定义小鸟类"""
    def __init__(self):
        """定义初始化方法"""
        self.birdStatus=[pygame.image.load("assets/0.png"),

                         pygame.image.load("assets/dead.png")]      #装载小鸟状态图片
        self.status=0
        self.birdX=120
        self.birdY=350
        self.jump=False
        self.jumpSpeed=10
        self.gravity=5
        self.dead=False
        self.birdRect=pygame.Rect(65,50,50,50)

    def birdUpdata(self):
        """定义小鸟移动方法"""
        if self.jump==True:
            """小鸟跳跃状态"""
            self.jumpSpeed-=1
            self.birdY-=self.jumpSpeed
        else:
            self.gravity+=0.2
            self.birdY+=self.gravity
        self.birdRect[1]=self.birdY
