python代码写一个坦克大战

以下是一个简单的坦克大战游戏的代码示例，使用Python语言编写：

import pygame, sys, random
from pygame.locals import *

# 初始化pygame
pygame.init()

# 设置游戏窗口大小和标题
WINDOW_WIDTH = 600
WINDOW_HEIGHT = 600
DISPLAYSURF = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption('Tank Battle')

# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)
BROWN = (153,76,0)

# 定义坦克类
class Tank(pygame.sprite.Sprite):
    def __init__(self, x, y, color):
        pygame.sprite.Sprite.__init__(self)
        self.color = color
        self.image = pygame.Surface((30, 40))
        self.image.fill(color)
        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = y
        self.speed = 5

    # 移动坦克
    def move(self, direction):
        if direction == 'up':
            self.rect.y -= self.speed
        elif direction == 'down':
            self.rect.y += self.speed
        elif direction == 'left':
            self.rect.x -= self.speed
        elif direction == 'right':
            self.rect.x += self.speed

    # 射击子弹
    def shoot(self):
        bullet = Bullet(self.rect.centerx, self.rect.centery, self.color)
        all_sprites_list.add(bullet)
        bullets_list.add(bullet)

# 定义子弹类
class Bullet(pygame.sprite.Sprite):
    def __init__(self, x, y, color):
        pygame.sprite.Sprite.__init__(self)
        self.color = color

        self.rect.x = x
        self.rect.y = y
        self.speed = 7

    # 移动子弹
    def update(self):
        self.rect.y -= self.speed
        if self.rect.bottom < 0:
            self.kill()

# 创建敌人坦克
def create_enemy_tank():
    x = random.randint(50, WINDOW_WIDTH - 50)
    y = random.randint(50, WINDOW_HEIGHT - 50)
    tank = Tank(x, y, RED)
    enemy_tanks_list.add(tank)
    all_sprites_list.add(tank)

# 初始化游戏
def game_init():
    global player_tank, enemy_tanks_list, bullets_list, all_sprites_list, score
    player_tank = Tank(WINDOW_WIDTH / 2 - 15, WINDOW_HEIGHT - 50, GREEN)
    enemy_tanks_list = pygame.sprite.Group()
    bullets_list = pygame.sprite.Group()
    all_sprites_list = pygame.sprite.Group()
    all_sprites_list.add(player_tank)
    score = 0

# 显示文字
def show_text(text, x, y, font_size):
    font = pygame.font.SysFont(None, font_size)
    text_obj = font.render(text, True, WHITE)
    text_rect = text_obj.get_rect()
    text_rect.centerx = x
    text_rect.centery = y
    DISPLAYSURF.blit(text_obj, text_rect)

# 游戏主循环
def game_loop():
    game_init()

    # 游戏是否结束
    game_over = False

    # 是否胜利
    win = False

    # 敌人坦克的数量
    enemy_tank_num = 3

    # 创建敌人坦克
    for i in range(enemy_tank_num):
        create_enemy_tank()

    # 游戏主循环
    while not game_over:

        # 处理事件
        for event in pygame.event.get():
            if event.type == QUIT:
                pygame.quit()
                sys.exit()
            elif event.type == KEYDOWN:
                if event.key == K_UP:
                    player_tank.move('up')
                elif event.key == K_DOWN:

            for enemy_tank in enemy_tanks_hit_list:
                bullets_list.remove(bullet)
                all_sprites_list.remove(bullet)
                score += 1
                create_enemy_tank()

        # 检测敌人坦克是否撞击到玩家坦克
        enemy_tanks_hit_list = pygame.sprite.spritecollide(player_tank, enemy_tanks_list, True)
        if len(enemy_tanks_hit_list) > 0:
            game_over = True

        # 绘制背景
        DISPLAYSURF.fill(BLACK)

        # 绘制分数
        show_text('Score: ' + str(score), 70, 20, 30)

        # 绘制玩家坦克和敌人坦克
        all_sprites_list.draw(DISPLAYSURF)

        # 更新屏幕
        pygame.display.update()

        # 判断胜利条件
        if score >= 10:
            win = True
            game_over = True

    # 游戏结束
    if win:
        show_text('You Win!', WINDOW_WIDTH / 2, WINDOW_HEIGHT / 2, 50)
    else:
        show_text('Game Over!', WINDOW_WIDTH / 2, WINDOW_HEIGHT / 2, 50)

    # 等待用户退出
    while True:
        for event in pygame.event.get():
            if event.type == QUIT or (event.type == KEYDOWN and event.key == K_ESCAPE):
                pygame.quit()
                sys.exit()

# 启动游戏
game_loop()

运行代码后，即可启动坦克大战游戏。玩家通过上下左右键控制自己的坦克移动，并按空格键发射子弹。击败敌人坦克获得分数，当分数达到10分时，玩家获胜；如果敌人坦克撞击到玩家坦克，则游戏失败。
