小时候玩的“坦克大战”，你还记得吗？
满满的回忆

整体效果
环境依赖
python3.7
pygame1.9.6
urllib
内置库，如random、sys、time、os等
pygame介绍
Pygame被设计用来写游戏的python模块集合，基于SDL库开发。使用python可以导入pygame来开发具有全部特性的游戏和多媒体软件，Pygame是极度轻便的并且可以运行在几乎所有的平台和操作系统上。
1. 导入依赖 & 通用配置
1import random 2import sys 3import time 4from urllib.request import urlretrieve 5import os 6import pygame 7 8 9SCREEN_WIDTH, SCREEN_HEIGHT = 1200, 700 # 画面大小 10MY_BIRTH_LEFT, MY_BIRTH_TOP = SCREEN_WIDTH / 2, SCREEN_HEIGHT - 60 11DIRECTION = [U, D, L, R] = [ U , D , L , R ] # 控制键 12Tank_IMAGE_POSITION = r D:/tank_img 13URL = https://gitee.com/tyoui/logo/raw/master/img/
2. 通用加载函数
1# 加载图片 2def load_img(name_img): 3 save = Tank_IMAGE_POSITION + os.sep + name_img + .gif 4 if not os.path.exists(save): 5 urlretrieve(URL + name_img + .gif , save) 6 return pygame.image.load(save) 7 8# 加载背景音乐 9def load_music(name_music): 10 save = Tank_IMAGE_POSITION + os.sep + name_music + .wav 11 if not os.path.exists(save): 12 urlretrieve(URL + name_music + .wav , save) 13 pygame.mixer.music.load(save) 14 pygame.mixer.music.play()
3. 通用基础类
1 2* pygame.sprite模块，官方文档上说这个模块是轻量级的，在游戏开发中也未必要使用。 3* sprite翻译为精灵，在游戏动画一般是指一个独立运动的画面元素，在pygame中， 4就可以是一个带有图像（Surface）和大小位置（Rect）的对象。 5* pygame.sprite.Sprite是pygame精灵的基类，一般来说，需要写一个自己的精灵类继承一下它然后加入自己的代码。 6 7class BaseItem(pygame.sprite.Sprite): 8 def __init__(self): 9 super().__init__()
4. 定义bullet类
1class Bullet(BaseItem): 2 # 参数初始化 3 def __init__(self, tank, window): 4 super().__init__() 5 self.direction = tank.direction 6 self.speed = tank.speed * 3 7 self.img = load_img( bullet ) 8 self.rect = self.img.get_rect() 9 self.window = window 10 self.live = True 11 if self.direction == U: 12 self.rect.left = tank.rect.left + tank.rect.width / 2 - self.rect.width / 2 13 self.rect.top = tank.rect.top - self.rect.height 14 elif self.direction == D: 15 self.rect.left = tank.rect.left + tank.rect.width / 2 - self.rect.width / 2 16 self.rect.top = tank.rect.top + tank.rect.height 17 elif self.direction == L: 18 self.rect.left = tank.rect.left - self.rect.width / 2 - self.rect.width / 2 19 self.rect.top = tank.rect.top + tank.rect.height / 2 - self.rect.height / 2 20 else: 21 self.rect.left = tank.rect.left + tank.rect.width 22 self.rect.top = tank.rect.top + tank.rect.height / 2 - self.rect.height / 2 23 24 # 子弹显示 25 def display_bullet(self): 26 self.window.blit(self.img, self.rect) 27 28 # 通过按键控制子弹移动 29 def bullet_move(self): 30 if self.direction == U: 31 if self.rect.top > 0: 32 self.rect.top -= self.speed 33 return 34 elif self.direction == D: 35 if self.rect.top < SCREEN_HEIGHT: 36 self.rect.top += self.speed 37 return 38 elif self.direction == L: 39 if self.rect.left > 0: 40 self.rect.left -= self.speed 41 return 42 else: 43 if self.rect.left < SCREEN_WIDTH: 44 self.rect.left += self.speed 45 return 46 self.live = False 47 48 # 我方坦克子弹击中对方坦克 49 def hit_enemy_tank(self): 50 for enemy in TankGame.enemy_tank_list: 51 hit = pygame.sprite.collide_rect(self, enemy) 52 if hit: 53 self.live = False 54 if enemy.click_count == 1: 55 enemy.live = False 56 return None 57 enemy.click_count -= 1 58 if enemy.click_count == 2: 59 enemy.load_image = enemy.img32 60 if enemy.click_count == 1: 61 enemy.load_image = enemy.img31 62 load_music( hit ) 63 64 # 对方坦克子弹击中我方坦克 65 def hit_my_tank(self, tank): 66 hit = pygame.sprite.collide_rect(self, tank) 67 if hit: 68 self.live = False 69 tank.live = False 70 71 # 子弹击中围墙 72 def bullet_collide_wall(self): 73 for wall in TankGame.wall_list: 74 result = pygame.sprite.collide_rect(self, wall) 75 if result: 76 self.live = False 77 if wall.count == 1: 78 wall.live = False 79 else: 80 load_music( hit ) 81 82 # 子弹击中子弹 83 def bullet_collide_bullet(self): 84 for bullet in TankGame.enemy_bullet_list: 85 if pygame.sprite.collide_rect(bullet, self): 86 bullet.live = False 87 self.live = False
