python实现飞机大战
本文实例为大家分享了python实现飞机大战的具体代码，供大家参考，具体内容如下
实现的效果如下：
主程序代码如下：
import pygame
from plane_sprites import *
class PlaneGame(object):
"""飞机大战主游戏"""
def __init__(self):
print("游戏初始化")
# 1，绘制屏幕窗口
self.screen = pygame.display.set_mode(SCREEN_RECT.size)
# 2，创建时钟
self.clock = pygame.time.Clock()
# 3，调用私有方法，精灵和精灵组的创建
self.sprite_creat()
# 4,设置定时器事件，创建敌机
pygame.time.set_timer(CREATE_ENEMY_EVENT, 400)
pygame.time.set_timer(HERO_FIRE_EVENT, 200)
def sprite_creat(self):
bg1 = BackGround()
bg2 = BackGround(True)
self.bg_group = pygame.sprite.Group(bg1, bg2)
self.enemy_group = pygame.sprite.Group()
# 创建英雄的精灵和精灵组
self.hero = Hero()
self.hero_group = pygame.sprite.Group(self.hero)
def start_game(self):
print("游戏开始。。。")
while True:
# 1，设置刷新帧率
self.clock.tick(FRAME_PER_SEC)
# 2，事件监听
self.__event_handle()
# 3，碰撞检测
self.__check_collide()
# 4，更新/绘制精灵和精灵组
self.__updtae_sprites()
# 5，更新显示
pygame.display.update()
def __event_handle(self):
for event in pygame.event.get():
if event.type == pygame.QUIT:
PlaneGame.__game_over()
elif event.type == CREATE_ENEMY_EVENT:
print("敌机出场。。。")
# 创建敌机精灵
enemy = Enemy()
# 敌机精灵添加到敌机精灵组
self.enemy_group.add(enemy)
elif event.type == HERO_FIRE_EVENT:
self.hero.fire()
# 移动英雄
keys_pressed = pygame.key.get_pressed()
if keys_pressed[pygame.K_RIGHT]:
self.hero.speed = 5
elif keys_pressed[pygame.K_LEFT]:
self.hero.speed = -5
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()
PlaneGame.__game_over()
def __updtae_sprites(self):
self.bg_group.update()
self.bg_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():
print("游戏结束了")
pygame.quit()
exit()
if __name__ == '__main__':
# 创建游戏对象

# 启动游戏
game.start_game()
各个类的代码如下：

# 创建发射子弹事件常量
HERO_FIRE_EVENT = pygame.USEREVENT + 1
