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

2. 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")

        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()

        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()

        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()
