Python game - bird pipe game [with original code]

foreword

Another small article about fishing~ I believe most people should have played this game

Not much to say, let's start the whole process now, finish it quickly, and catch fish quickly

I have to say that this little game is quite challenging.

Principle introduction

FlappyBird Game Introduction:

The player uses the space bar to control a bird to cross obstacles made up of water pipes of various lengths. When the bird hits the obstacle or falls to the bottom of the screen, the game ends.

Step by step:

Step1: Define the sprite class

In order to facilitate the detection of the collision between the bird and the water pipe,

Let's define some sprite classes first, including:

① small birds

material:

    def __init__(self):
        """定义初始化方法"""
        self.birdRect = pygame.Rect(65, 50, 50, 50)  # 鸟的矩形
        # 定义鸟的3种状态列表
        self.birdStatus = [pygame.image.load("assets/1.png"),
                           pygame.image.load("assets/2.png"),
                           pygame.image.load("assets/dead.png")]
        self.status = 0      # 默认飞行状态
        self.birdX = 120     # 鸟所在X轴坐标,即是向右飞行的速度
        self.birdY = 350     # 鸟所在Y轴坐标,即上下飞行高度
        self.jump = False    # 默认情况小鸟自动降落
        self.jumpSpeed = 20  # 跳跃高度
        self.gravity = 3     # 重力
        self.dead = False    # 默认小鸟生命状态为活着

    def birdUpdate(self):
        if self.jump:
            # 小鸟跳跃
            self.jumpSpeed -= 1           # 速度递减，上升越来越慢
            self.birdY -= self.jumpSpeed  # 鸟Y轴坐标减小，小鸟上升
        else:
            # 小鸟坠落
            self.gravity += 0.2           # 重力递增，下降越来越快
            self.birdY += self.gravity    # 鸟Y轴坐标增加，小鸟下降
        self.birdRect[1] = self.birdY     # 更改Y轴位置

② Pipes

The pipe is divided into a pipe body and a pipe head.

Pipe Upper:

Pipe Lower:

Game Background

    def __init__(self):
        """定义初始化方法"""
        self.wallx = 400  # 管道所在X轴坐标
        self.pineUp = pygame.image.load("assets/top.png")
        self.pineDown = pygame.image.load("assets/bottom.png")

    def updatePipeline(self):
        """"管道移动方法"""
        self.wallx -= 5  # 管道X轴坐标递减，即管道向左移动
        # 当管道运行到一定位置，即小鸟飞越管道，分数加1，并且重置管道
        if self.wallx < -80:
            global score
            score += 1
            self.wallx = 400

Create the map and set the pipeline, bird position and state, and don't forget to set the score:

def createMap():
    """定义创建地图的方法"""
    screen.fill((255, 255, 255))     # 填充颜色
    screen.blit(background, (0, 0))  # 填入到背景

    # 显示管道
    screen.blit(Pipeline.pineUp, (Pipeline.wallx, -300))   # 上管道坐标位置
    screen.blit(Pipeline.pineDown, (Pipeline.wallx, 500))  # 下管道坐标位置
    Pipeline.updatePipeline()  # 管道移动

    # 显示小鸟
    if Bird.dead:              # 撞管道状态
        Bird.status = 2
    elif Bird.jump:            # 起飞状态
        Bird.status = 1
    screen.blit(Bird.birdStatus[Bird.status], (Bird.birdX, Bird.birdY))              # 设置小鸟的坐标
    Bird.birdUpdate()          # 鸟移动

    # 显示分数
    screen.blit(font.render('Score:' + str(score), -1, (255, 255, 255)), (100, 50))  # 设置颜色及坐标位置
    pygame.display.update()    # 更新显示

detect collision

def checkDead():
    # 上方管子的矩形位置
    upRect = pygame.Rect(Pipeline.wallx, -300,
                         Pipeline.pineUp.get_width() - 10,
                         Pipeline.pineUp.get_height())

    # 下方管子的矩形位置
    downRect = pygame.Rect(Pipeline.wallx, 500,
                           Pipeline.pineDown.get_width() - 10,
                           Pipeline.pineDown.get_height())
    # 检测小鸟与上下方管子是否碰撞
    if upRect.colliderect(Bird.birdRect) or downRect.colliderect(Bird.birdRect):
        Bird.dead = True
    # 检测小鸟是否飞出上下边界
    if not 0 < Bird.birdRect[1] < height:
        Bird.dead = True
        return True
    else:
        return False

Step2: Implement the main loop of the game

First initialize, load pictures, music, fonts and other files,

and define some necessary constants:

if __name__ == '__main__':
    """主程序"""
    pygame.init()                            # 初始化pygame
    pygame.font.init()                       # 初始化字体
    font = pygame.font.SysFont("ziti.ttf", 50)  # 设置字体和大小
    size = width, height = 400, 650          # 设置窗口
    screen = pygame.display.set_mode(size)   # 显示窗口
    clock = pygame.time.Clock()              # 设置时钟
    Pipeline = Pipeline()                    # 实例化管道类
    Bird = Bird()                            # 实例化鸟类
    score = 0
    while True:
        clock.tick(60)                       # 每秒执行60次
        # 轮询事件
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit()
            if (event.type == pygame.KEYDOWN or event.type == pygame.MOUSEBUTTONDOWN) and not Bird.dead:
                Bird.jump = True             # 跳跃
                Bird.gravity = 5             # 重力
                Bird.jumpSpeed = 10          # 跳跃速度

        background = pygame.image.load("assets/background.png")  # 加载背景图片
        if checkDead():                      # 检测小鸟生命状态
            getResutl()                      # 如果小鸟死亡，显示游戏总分数
        else:
            createMap()                      # 创建地图
    pygame.quit()

All Done！
