消灭病毒游戏
消灭病毒是一个打飞机类型游戏，游戏开始界面如下，病毒有生命值，一颗子弹伤害为10
病毒生命值为0时则消失，飞机撞到病毒游戏结束游戏结束时显示分数
以下是游戏代码：
1、主程序代码
import pygame
from airplane import Airplane

screen.fill([0, 0, 0])

screen.blit(over_screen, (200, 240))
highscorestr = 'YOUR SCORE IS ' + str(scorenum) #显示得分
over_screen = my_font.render(highscorestr, True, (255, 0, 0))
screen.blit(over_screen, (200, 290))
global count_num #分数是一个全局变量，在这里重置为0
count_num = 0
airplane.rect.centerx = 300 #飞机位置重置
airplane.rect.top = 800 - 54
pygame.display.update() # 刷新
pygame.time.delay(1000)
if __name__ == '__main__':
pygame.init() # 初始化
pygame.mixer.init()

# 左上角计算分数
countObj = pygame.font.SysFont('arial', 50)
textObj = countObj.render('SCORE:0', True, (255, 0, 0))
textRectObj = textObj.get_rect()
screen.blit(textObj, textRectObj)
# 这个是计算分数
count_num = 0
# 创建飞机
airplane = Airplane(screen)
# 子弹容器
bullet_sprites = pygame.sprite.RenderUpdates() # 创建sprite容器 树
AddEnemy = pygame.USEREVENT + 1 # 添加子弹的时间
pygame.time.set_timer(AddEnemy, 300)
pygame.display.flip()

pygame.display.update(bullet_updates)
# 子弹和病毒组的碰撞
hit_list = pygame.sprite.groupcollide(bullet_sprites, virusers.group, True, False)
'''得分'''
if hit_list.values().__len__(): # hit_list.values() 返回就是病毒精灵
for obj in hit_list.values():

2、飞机类
import pygame
class Airplane(pygame.sprite.Sprite):
def __init__(self,screen):
pygame.sprite.Sprite.__init__(self)
self.screen = screen
self.image = pygame.image.load('./airplane.jpg')
self.rect = self.image.get_rect()
self.rect.centerx = 300
self.rect.top = 800 - 54
self.speed = 4
# 根据按键事件来移动
def update(self, pressed_keys):
# 按键事件
if pressed_keys[pygame.K_LEFT] or pressed_keys[pygame.K_a]:
if self.rect.left > 0:
self.rect.left -= self.speed
elif pressed_keys[pygame.K_RIGHT] or pressed_keys[pygame.K_d]:
if self.rect.left < 600 - self.image.get_width():
self.rect.left += self.speed
if pressed_keys[pygame.K_UP] or pressed_keys[pygame.K_w]:

elif pressed_keys[pygame.K_DOWN] or pressed_keys[pygame.K_s]:
if self.rect.top < 800 - self.image.get_height():
self.rect.top += self.speed
3、子弹类
import pygame
#这是子弹类
class Bullet(pygame.sprite.Sprite):
"""A class to manage bullets fired from the ship."""
def __init__(self, screen, ship):
"""Create a bullet object, at the ship's current position."""
super().__init__()
self.screen = screen
self.image = pygame.image.load('./bullet.png')
self.damage = 2 #子弹每一发的伤害
# Create bullet rect at (0, 0), then set correct position.
self.rect = self.image.get_rect()
self.rect.centerx = ship.rect.centerx
self.rect.top = ship.rect.top
self.speed = 5
def update(self):
"""Move the bullet up the screen."""
# Update the decimal position of the bullet.
self.rect.y -= self.speed
if self.rect.top < -self.rect.height:
self.kill()
4、病毒类
import pygame
import sys
import random
# 病毒类
class Viruses(pygame.sprite.Sprite):
Flag = False
def __init__(self, image, position, x_speed, y_speed):
'''
初始化
:param image: 图片名字
:param position: 位置
:param x_speed: 水平的速度
:param y_speed: 竖直的速度
:param score: 生命值
'''

self.image = pygame.image.load(image)
self.rect = self.image.get_rect()
self.rect.center = position
self.X_speed = x_speed
self.Y_speed = y_speed
if image == '2.png':
self.score = 20
elif image == '3.png':
self.score = 10
''' 移动 '''
def update(self, *args):
self.rect = self.rect.move(self.X_speed, self.Y_speed)
if self.rect.left < 0 or self.rect.right > 600:
self.X_speed = -self.X_speed
if self.rect.bottom > 800 + self.rect.height:
self.rect.top = -self.rect.height
if not self.score:
self.kill()
elif self.score == 10:
self.trun(1)
''' 换图 '''
def trun(self, value):
if value == 0:
self.image = pygame.image.load(viruses_images[value])
elif value == 1:
self.image = pygame.image.load(viruses_images[value])
group = pygame.sprite.Group()
viruses_images = ['2.png', '3.png']
# 初始化精灵组
def viruse_new():
position_list = []
for i in range(10):
row = random.randint(0, 8)
col = random.randint(0, 9)
position = [row * 60 + 33, - col * 60 - 50]
if position not in position_list:
position_list.append(position)
image_name = random.choice(viruses_images)
obj = Viruses(image_name, position, random.randint(0, 3), random.randint(1, 3))
group.add(obj)
