从零开始玩python--python版植物大战僵尸来袭

大家好呀，小伙伴们！今天要给大家介绍一个超有趣的Python项目 - 用pygame制作植物大战僵尸游戏的进阶版本。相信不少小伙伴都玩过这款经典游戏，今天我们就用Python来实现它，让编程学习变得更加有趣！🌟

一、环境准备

首先需要安装pygame库，它是Python中非常强大的游戏开发库。打开终端输入以下命令：

pip install pygame

小贴士：建议使用Python 3.6及以上版本，确保兼容性更好哦！

二、基础架构搭建

让我们先来搭建游戏的基本框架：

import pygame
import random
import sys# 初始化pygame
pygame.init()# 设置游戏窗口
WINDOW_WIDTH = 800
WINDOW_HEIGHT = 600
screen = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption('植物大战僵尸 - Python版')# 定义颜色
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)# 创建游戏时钟
clock = pygame.time.Clock()# 基础游戏类
class GameObject:def __init__(self, x, y):self.x = xself.y = yself.rect = pygame.Rect(x, y, 40, 40)  # 默认大小为40x40def draw(self, surface):pygame.draw.rect(surface, GREEN, self.rect)

三、核心gameplay实现

接下来实现游戏的核心玩法：

# 植物类
class Plant(GameObject):def __init__(self, x, y):super().__init__(x, y)self.health = 100self.attack_power = 20self.shoot_cooldown = 60  # 发射冷却时间self.cooldown_counter = 0def shoot(self):if self.cooldown_counter <= 0:self.cooldown_counter = self.shoot_cooldownreturn Projectile(self.x + 40, self.y + 20)return Nonedef update(self):if self.cooldown_counter > 0:self.cooldown_counter -= 1# 僵尸类
class Zombie(GameObject):def __init__(self, x, y):super().__init__(x, y)self.health = 100self.speed = 1self.damage = 10def move(self):self.x -= self.speedself.rect.x = self.xdef is_alive(self):return self.health > 0# 子弹类
class Projectile(GameObject):def __init__(self, x, y):super().__init__(x, y)self.speed = 5self.damage = 20self.rect = pygame.Rect(x, y, 10, 10)def move(self):self.x += self.speedself.rect.x = self.x

四、游戏主循环

现在来实现游戏的主循环逻辑：

def main():plants = []zombies = []projectiles = []score = 0# 游戏主循环running = Truewhile running:# 事件处理for event in pygame.event.get():if event.type == pygame.QUIT:running = Falseelif event.type == pygame.MOUSEBUTTONDOWN:# 点击放置植物x, y = pygame.mouse.get_pos()plants.append(Plant(x - 20, y - 20))# 随机生成僵尸if random.randint(0, 100) < 2:  # 2%的概率生成僵尸zombies.append(Zombie(WINDOW_WIDTH, random.randint(100, WINDOW_HEIGHT - 100)))# 更新游戏状态screen.fill(WHITE)# 更新植物for plant in plants:plant.update()plant.draw(screen)projectile = plant.shoot()if projectile:projectiles.append(projectile)# 更新僵尸for zombie in zombies[:]:zombie.move()zombie.draw(screen)# 检查僵尸是否到达最左边if zombie.x < 0:running = Falsebreak# 更新子弹for projectile in projectiles[:]:projectile.move()projectile.draw(screen)# 检查子弹碰撞for zombie in zombies[:]:if projectile.rect.colliderect(zombie.rect):zombie.health -= projectile.damageprojectiles.remove(projectile)if not zombie.is_alive():zombies.remove(zombie)score += 100break# 移除超出屏幕的子弹if projectile.x > WINDOW_WIDTH:projectiles.remove(projectile)# 显示分数font = pygame.font.Font(None, 36)score_text = font.render(f'Score: {score}', True, (0, 0, 0))screen.blit(score_text, (10, 10))pygame.display.flip()clock.tick(60)pygame.quit()sys.exit()if __name__ == '__main__':main()

五、游戏优化与扩展

让我们来给游戏添加一些有趣的功能：

多种植物类型：

class SunFlower(Plant):def __init__(self, x, y):super().__init__(x, y)self.sun_production_rate = 25self.sun_cooldown = 300def produce_sun(self):if self.cooldown_counter <= 0:self.cooldown_counter = self.sun_cooldownreturn Truereturn Falseclass PeaShooter(Plant):def __init__(self, x, y):super().__init__(x, y)self.attack_power = 20self.shoot_cooldown = 60

小贴士：可以根据需要继续添加更多植物类型，比如坚果墙、寒冰射手等！

实际应用案例：

游戏存档功能：

import jsondef save_game(score, plants, zombies):game_state = {'score': score,'plants': [(p.x, p.y) for p in plants],'zombies': [(z.x, z.y, z.health) for z in zombies]}with open('game_save.json', 'w') as f:json.dump(game_state, f)def load_game():try:with open('game_save.json', 'r') as f:return json.load(f)except FileNotFoundError:return None
