Python 实现飞机大战简单版

这版和网上流传的大部分差不多，没有声音，不能计分。有时间会写个的
首先你得安装了Python3 和pygame ，最好用pycharm编写。

1. 第一步我们先做一些准备工作：
   测试pygame是否能运行

import pygame

pygame.init()
#创建游戏窗口
screen = pygame.display.set_mode((480,700))
bg = pygame.image.load("./images/background.png")
screen.blit(bg,(0,0))
pygame.display.update()

while True:
pass
pygame.quit()

上面代码我没写定时关闭，运行时注意

1. 写英雄图像

import pygame
pygame.init()
#创建游戏窗口
screen = pygame.display.set_mode((480,700))
bg = pygame.image.load("./images/ul0961-7549.jpg")
screen.blit(bg,(0,0))
pygame.display.update()
#英雄图像
hero = pygame.image.load("./images/me1.png")
screen.blit(hero,(200,500))
pygame.display.update()
clock = pygame.time.Clock()
hero_rect = pygame.Rect(200, 500, 102, 126)
while True:
clock.tick(60)

for event in  pygame.event.get():

if event.type == pygame.QUIT:
print("游戏退出...")
pygame.quit()
exit()

hero_rect.y -= 2
if hero_rect.y <=0:
hero_rect.y = 700

screen.blit(bg,(0,0))
screen.blit(hero, hero_rect)
pygame.display.update()

pygame.quit()

“”

3 写敌机

import pygame
from piane_sprites import*

pygame.init()
#创建游戏窗口
screen = pygame.display.set_mode((480,700))
bg = pygame.image.load("./images/ul0961-7549.jpg")
screen.blit(bg,(0,0))
pygame.display.update()
#英雄图像
hero = pygame.image.load("./images/me1.png")
screen.blit(hero,(200,500))
pygame.display.update()
clock = pygame.time.Clock()
hero_rect = pygame.Rect(200, 500, 102, 126)
enemy = GameSprite("./images/enemy1.png")
enemy1= GameSprite("./images/enemy1.png",2)
enemy_group = pygame.sprite.Group(enemy,enemy1)

while True:
clock.tick(60)
for event in  pygame.event.get():

if event.type == pygame.QUIT:
print("游戏退出...")
pygame.quit()
exit()
hero_rect.y -= 5
if hero_rect.y <=0:
hero_rect.y = 700

screen.blit(bg,(0,0))
screen.blit(hero, hero_rect)

enemy_group.update()
enemy_group.draw(screen)

pygame.display.update()
pygame.quit()

接下来就写我们的主程序了
1、主程序：plane_main.py

import pygame
from piane_sprites import*

class PianeGame(object):

def __init__(self):
print("游戏初始化")

#1.创建游戏的窗口
self.screen = pygame.display.set_mode(SCREEN_RECT.size)
#2.创建游戏的时钟
self.clock = pygame.time.Clock()

self.__create_sprites()
pygame.time.set_timer(CREATE_ENEMY_EVENT,1000)
pygame.time.set_timer(HERO_FIRE_EVENT,500)

def __create_sprites(self):

bg1 = Background()
bg2 = Background(True)
bg2.rect.y = -bg2.rect.height
self.back_group = pygame.sprite.Group(bg1,bg2)
self.enemy_group = pygame.sprite.Group()
self.hero = Hero()
self.hero_group = pygame.sprite.Group(self.hero)
def start_game(self):
print("游戏开始...")

while True:
self.clock.tick(FRAME_SEPER_C)
self.__event_handler()
self.__check_collide()
self.__update_sprites()
pygame.display.update()

def __event_handler(self):
for event in pygame.event.get():
if event.type ==pygame.QUIT:
PianeGame.__game_over()
elif event.type == CREATE_ENEMY_EVENT:
enemy = Enemy()
self.enemy_group.add(enemy)
elif event.type == HERO_FIRE_EVENT:
self.hero.fire()
#elif event.type == pygame.KEYDOWN and_event.key == pygme.K_RIG
#  print("")
keys_pressed = pygame.key.get_pressed()
if keys_pressed[pygame.K_RIGHT]:
self.hero.speed = 3
elif keys_pressed[pygame.K_LEFT]:
self.hero.speed = -3
else:
self.hero.speed = 0

def __check_collide(self):
pygame.sprite.groupcollide(self.hero.bullets,self.enemy_group,True,True)
enemies = pygame.sprite.spritecollide(self.hero, self.enemy_group, True)
if len(enemies)>0:
self.hero.kill()
self.__game_over()
def __update_sprites(self):

self.back_group.update()
self.back_group.draw(self.screen)

self.enemy_group.update()
self.enemy_group.draw(self.screen)

self.hero_group.update()
self.hero_group.draw(self.screen)

self.hero.bullets.update()
self.hero.bullets.draw(self.screen)
@staticmethod
def __game_over(self):
print("游戏结束")
if __name__ == '__main__':
game = PianeGame()
game.start_game()

2.游戏精灵：plane_sprites.py

import pygame

#英雄发射子弹事件
HERO_FIRE_EVENT = pygame.USEREVENT + 1

class GameSprite(pygame.sprite.Sprite):

def __init__(self,image_name, speed=1):
# 调用父类的初始化方法
super().__init__()

# 定义对象的属性
self.image = pygame.image.load(image_name)
self.rect  = self.image.get_rect()
self.speed = speed

def update(self):
# 在屏幕的垂直方向上移动
self.rect.y += self.speed
class Background(GameSprite):
"""游戏背景精灵"""
def __init__(self,is_alt=False):
#1.调用父类方法实现精灵的创建
super().__init__("./images/background.png")

#2.判断是否交替图像，如果是需要设置初始位置
if is_alt:
self.rect.y = -self.rect.height

def update(self):
#1.调用父类的方法实现
super().update()
#2.判断是否移出屏幕，如果移出屏幕，将设置到屏幕的上方
if self.rect.y >= SCREEN_RECT.height:
self.rect.y = -self.rect
4000
.height

class Enemy(GameSprite):

def __init__(self):

print()
self.kill()
def __del__(self):
print()

class Hero(GameSprite):

self.rect.centerx = SCREEN_RECT.centerx
self.rect.bottom = SCREEN_RECT.bottom - 120

self.bullets = pygame.sprite.Group()
def update(self):
self.rect.x += self.speed
if self.rect.x < 0:
self.rect.x = 0
elif self.rect.right > SCREEN_RECT.right:
self.rect.right = SCREEN_RECT.right
def fire(self):
print()
for i in (0,1,2):

bullet = Bullet()
bullet.rect.bottom = self.rect.y - i * 20
bullet.rect.centerx = self.rect.centerx

self.bullets.add(bullet)

pass
