python实现简单飞机大战小游戏
为了熟悉Python基础语法，学习了一个经典的案例：飞机大战，最后实现效果如下：
实现步骤：
①下载64位对应python版本的pygame：pygame-1.9.6-cp38-cp38-win_amd64.whl
② 更新pip：python -m pip install --upgrade pip
③ 安装pygame：pip install pygame-1.9.6-cp38-cp38-win_amd64.whl
④ 实现代码如下：
import sys # 导入系统模块
import random # 随机数模块
import pygame # 导入pygame模块
import pygame.locals # 导入pygame本地策略
ICO_PATH = "images/app.ico" # APP_ICO
APP_NAME = "飞机大战V1.0" # APP_NAME
Enemy_IMGS = ("images/enemy1.png", "images/enemy2.png") # ENEMY_IMGS
# TODO 定义一个公共类
class Model:
window = None # 主窗体window对象
# 初始化函数
def __init__(self, img_path, x, y):
self.img = pygame.image.load(img_path)
self.x = x
self.y = y
# 将图片填充到背景中
def display(self):
Model.window.blit(self.img, (self.x, self.y))
# TODO 背景
class Background(Model):
# 背景移动
def move(self):
if self.y <= Game.WINDOW_HEIGHT:
self.y += 1
else:
self.y = 0
# 背景图片展示
def display(self):
Model.window.blit(self.img, (self.x, self.y)) # 填充背景
Model.window.blit(self.img, (self.x, self.y - Game.WINDOW_HEIGHT)) # 填充辅助背景
# TODO 玩家类
class PlayerPlane(Model):
def __init__(self, img_path, x, y):
super().__init__(img_path, x, y)
# 子弹
self.bullets = []
def display(self, enemys):
super().display()
remove_bullets = []
for bullet in self.bullets:
bullet.move()
bullet.display()
# 如果子弹小于消失于屏幕，删除子弹
if bullet.y < -11:
remove_bullets.append(bullet)
# 子弹的矩阵
bullet_rect = pygame.locals.Rect(bullet.x, bullet.y, 5, 11)
# TODO 进行碰撞检测
for enemy in enemys:
# 敌机的矩阵
enemy_rect = pygame.locals.Rect(enemy.x, enemy.y, 57, 43)
# 如果碰撞
if pygame.Rect.colliderect(bullet_rect, enemy_rect):
# 随机修改敌机的位置模拟敌机销毁并生成新敌机并删除子弹
enemy.img = pygame.image.load(Enemy_IMGS[random.randint(0, 1)])
enemy.x = random.randint(0, Game.WINDOW_WIDTH - 57)
enemy.y = random.randint(-Game.WINDOW_WIDTH, -43)
remove_bullets.append(bullet)
break

self.bullets.remove(bullet)
# TODO 敌机类

self.y = random.randint(-Game.WINDOW_WIDTH, -43)
def move(self):
if self.y > Game.WINDOW_HEIGHT:
self.y = -43 # 返回初始位置
else:
self.y += 1
# TODO 子弹类
class Bullet(Model):
def move(self):
self.y -= 1
# TODO 游戏类
class Game:
WINDOW_WIDTH = 410
WINDOW_HEIGHT = 614
# 初始化操作
def __init__(self):
self.window = pygame.display.set_mode([Game.WINDOW_WIDTH, Game.WINDOW_HEIGHT]) # 窗口的设置
self.background = Background("images/background.png", 0, 0) # 窗体模型的设置
self.player = PlayerPlane("images/me1.png", 180, 400)
self.enemyPlanes = []
for _ in range(5):
self.enemyPlanes.append(EnemyPlane())
# 游戏的入口函数
def run(self):
self.frame_init()
while True:
self.background.move() # 背景向上移动，模拟环境移动
self.background.display() # 将图片塞入到窗体中
self.player.display(self.enemyPlanes)
for enemy in self.enemyPlanes:
enemy.move()
enemy.display()
pygame.display.update() # 刷新窗体
self.event_init() # 监听事件
# 初始化窗口
def frame_init(self):
Model.window = self.window # 将window对象赋值给Model公有类
ico = pygame.image.load(ICO_PATH) # 加载图片
pygame.display.set_icon(ico) # 设置icon
pygame.display.set_caption(APP_NAME) # 设置app_name
# 事件初始化方法
def event_init(self):
for event in pygame.event.get():
# 关闭事件
if event.type == pygame.locals.QUIT:
sys.exit()
# 监听鼠标事件
if event.type == pygame.locals.MOUSEMOTION:
pos = pygame.mouse.get_pos()
self.player.x = pos[0] - 51
self.player.y = pos[1] - 63
focus_state = pygame.mouse.get_pressed()
if focus_state[0] == 1:
pos = pygame.mouse.get_pos()
self.player.bullets.append(Bullet("images/bullet1.png", pos[0], pos[1] - 75))
if __name__ == "__main__":
Game().run()
