Python开发：飞机大战小游戏

1.创建窗口

import pygame import time def main(): #1.创建窗口 screen = pygame.display.set_mode((480,852)) #2 创建一个背景图片 background = pygame.image.load('./feiji/background.png') while True: #3 显示到屏幕 screen.blit(background,(0,0)) pygame.display.update() time.sleep(0.05) if __name__ == '__main__': main()

2.显示玩家飞机，检测键盘，控制飞机左右移动

import pygame import time from pygame.locals import * class HeroPlane(object): def __init__(self,screen_temp): self.x = 210 self.y = 700 self.screen = screen_temp #游戏窗口 self.image = pygame.image.load('feiji/hero1.png') def display(self): self.screen.blit(self.image,(self.x,self.y)) #加载玩家飞机到窗口 def move_left(self): self.x -= 5 def move_right(self): self.x = 5 def key_control(hero_temp): # 获取事件，比如按键等 for event in pygame.event.get(): # 判断是否是点击了退出按钮 if event.type == QUIT: print("exit") exit() # 判断是否是按下了键 elif event.type == KEYDOWN: # 检测按键是否是a或者left if event.key == K_a or event.key == K_LEFT: print('left') hero_temp.move_left() # 检测按键是否是d或者right elif event.key == K_d or event.key == K_RIGHT: print('right') hero_temp.move_right() # 检测按键是否是空格键 elif event.key == K_SPACE: print('space') def main(): #1.创建窗口 screen = pygame.display.set_mode((480,852),0,0) #2 创建一个背景图片 background = pygame.image.load('./feiji/background.png') # 创建一个飞机对象 hero = HeroPlane(screen) while True: #把背景图片放到窗口显示 screen.blit(background,(0,0)) #显示玩家飞机到定义的（x,y）坐标位置 hero.display() pygame.display.update() #检测键盘，控制玩家飞机移动 key_control(hero) time.sleep(0.05) if __name__ == '__main__': main()

3.玩家发射子弹

import pygame import time from pygame.locals import * class HeroPlane(object): def __init__(self,screen_temp): self.x = 210 self.y = 700 self.screen = screen_temp #游戏窗口 self.image = pygame.image.load('feiji/hero1.png') self.bullet_list = [] #存储发射出去的子弹 def display(self): # 加载玩家飞机到窗口 self.screen.blit(self.image,(self.x,self.y)) for bullet in self.bullet_list: bullet.display() bullet.move() def move_left(self): self.x -= 5 def move_right(self): self.x = 5 def fire(self): self.bullet_list.append(Bullet(self.screen,self.x,self.y)) class Bullet(object): def __init__(self,screen_temp,x,y): self.x = x 40 self.y = y - 20 self.screen = screen_temp self.image = pygame.image.load('feiji/bullet.png') def display(self): self.screen.blit(self.image,(self.x,self.y)) def move(self): self.y -= 20 def key_control(hero_temp): # 获取事件，比如按键等 for event in pygame.event.get(): # 判断是否是点击了退出按钮 if event.type == QUIT: print("exit") exit() # 判断是否是按下了键 elif event.type == KEYDOWN: # 检测按键是否是a或者left if event.key == K_a or event.key == K_LEFT: print('left') hero_temp.move_left() # 检测按键是否是d或者right elif event.key == K_d or event.key == K_RIGHT: print('right') hero_temp.move_right() # 检测按键是否是空格键 elif event.key == K_SPACE: print('space') hero_temp.fire() def main(): #1.创建窗口 screen = pygame.display.set_mode((480,852),0,0) #2 创建一个背景图片 background = pygame.image.load('./feiji/background.png') # 创建一个飞机对象 hero = HeroPlane(screen) while True: #把背景图片放到窗口显示 screen.blit(background,(0,0)) #显示玩家飞机到定义的（x,y）坐标位置 hero.display() pygame.display.update() #检测键盘，控制玩家飞机移动 key_control(hero) time.sleep(0.05) if __name__ == '__main__': main()

效果如下：

4.创建一个敌机

--snip-- class EnemyPlane(object): def __init__(self,screen_temp): self.x = 0 self.y = 0 self.screen = screen_temp self.image = pygame.image.load('feiji/enemy0.png') def display(self): self.screen.blit(self.image,(self.x,self.y)) --snip-- def main(): --snip-- #4 创建一个敌机 enemy = EnemyPlane(screen) while True: --snip-- enemy.display() --snip

5.控制敌机左右移动

--snip-- class EnemyPlane(object): def __init__(self,screen_temp): --snip-- self.direction = 'right' #定义敌机默认往右移动 --snip-- def move(self): if self.direction == 'right': self.x = 8 elif self.direction == 'left': self.x -= 8 if self.x > 430: self.direction = 'left' elif self.x < 0: self.direction = 'right' --snip-- def main(): --snip-- #4 创建一个敌机 enemy = EnemyPlane(screen) enemy.move() 　　--snip--

6.删除子弹，只要发射出去的子弹超过边界就删掉

--snip-- class HeroPlane(object): --snip-- --snip-- bullet.move() if bullet.judge(): #判断子弹是否越界 self.bullet_list.remove(bullet) --snip-- class Bullet(object): --sinp-- def judge(self): if self.y < 0: return True else: return False --snip

7.添加敌机放射子弹功能

使用random来控制敌机发射子弹的频率

--snip-- import random class EnemyPlane(object): --snip - - self.bullet_list = [] #存储发射出去的子弹 self.direction = 'right' #定义敌机默认往右移动 def display(self): --snip - - bullet.move() if bullet.judge(): #判断子弹是否越界 self.bullet_list.remove(bullet) --snip-- def fire(self): #控制子弹频率 random_num = random.randint(1,80) if random_num == 10 or random_num == 40: self.bullet_list.append(EnemyBullet(self.screen,self.x,self.y)) --snip-- class EnemyBullet(object): def __init__(self,screen_temp,x,y): self.x = x 25 self.y = y 40 self.screen = screen_temp self.image = pygame.image.load('feiji/bullet1.png') def display(self): self.screen.blit(self.image,(self.x,self.y)) def move(self): self.y = 10 def judge(self): if self.y > 852: return True else: return False --snip - - while True: --snip - - enemy.move() enemy.fire() --snip--

最终效果

8.优化代码，创建基类
