大家好，我是 A梦。

今天给大家带来一个 Python 的练手项目。用Python的Pygame游戏开发库编写代码写一个植物大战僵尸！

直接开搞！

1. 引入需要的模块

import pygame
import random

2. 配置图片地址

IMAGE_PATH = 'imgs/'

3. 设置页面宽高

scrrr_width = 800
scrrr_height = 560

4. 创建控制游戏结束的状态

GAMEOVER = False

5. 图片加载报错处理

LOG = '文件:{}中的方法:{}出错'.format(__file__, __name__)

6. 创建地图类

class Map():

7. 存储两张不同颜色的图片名称

map_names_list = [IMAGE_PATH + 'map1.png', IMAGE_PATH + 'map2.png']

8. 初始化地图

def __init__(self, x, y, img_index):self.image = pygame.image.load(Map.map_names_list[img_index])self.position = (x, y)

9. 是否能够种植

self.can_grow = True

10. 加载地图

def load_map(self):MainGame.window.blit(self.image, self.position)

11. 植物类

class Plant(pygame.sprite.Sprite):def __init__(self):super(Plant, self).__init__()self.live = True

12. 加载图片

def load_image(self):if hasattr(self, 'image') and hasattr(self, 'rect'):MainGame.window.blit(self.image, self.rect)else:print(LOG)

13. 向日葵类

class Sunflower(Plant):def __init__(self, x, y):super(Sunflower, self).__init__()self.image = pygame.image.load('imgs/sunflower.png')self.rect = self.image.get_rect()self.rect.x = xself.rect.y = yself.price = 50self.hp = 100# 5 时间计数器self.time_count = 0

14. 新增功能：生成阳光

def produce_money(self):self.time_count += 1if self.time_count == 25:MainGame.money += 5self.time_count = 0

15. 向日葵加入到窗口中

def display_sunflower(self):MainGame.window.blit(self.image, self.rect)

16. 豌豆射手类

class PeaShooter(Plant):def __init__(self, x, y):super(PeaShooter, self).__init__()# self.image 为一个 surfaceself.image = pygame.image.load('imgs/peashooter.png')self.rect = self.image.get_rect()self.rect.x = xself.rect.y = yself.price = 50self.hp = 200# 6 发射计数器self.shot_count = 0

17. 增加射击方法

def shot(self):# 6 记录是否应该射击should_fire = Falsefor zombie in MainGame.zombie_list:if zombie.rect.y == self.rect.y and zombie.rect.x < 800 and zombie.rect.x > self.rect.x:should_fire = True# 6 如果活着if self.live and should_fire:self.shot_count += 1# 6 计数器到25发射一次if self.shot_count == 25:# 6 基于当前豌豆射手的位置，创建子弹peabullet = PeaBullet(self)# 6 将子弹存储到子弹列表中MainGame.peabullet_list.append(peabullet)self.shot_count = 0

18. 将豌豆射手加入到窗口中的方法

def display_peashooter(self):MainGame.window.blit(self.image, self.rect)

19. 豌豆子弹类

class PeaBullet(pygame.sprite.Sprite):def __init__(self, peashooter):self.live = Trueself.image = pygame.image.load('imgs/peabullet.png')self.damage = 50self.speed = 10self.rect = self.image.get_rect()self.rect.x = peashooter.rect.x + 60self.rect.y = peashooter.rect.y + 15def move_bullet(self):# 7 在屏幕范围内，实现往右移动if self.rect.x < scrrr_width:self.rect.x += self.speedelse:self.live = False# 7 新增，子弹与僵尸的碰撞def hit_zombie(self):for zombie in MainGame.zombie_list:if pygame.sprite.collide_rect(self, zombie):# 打中僵尸之后，修改子弹的状态，self.live = False# 僵尸掉血zombie.hp -= self.damageif zombie.hp <= 0:zombie.live = Falseself.nextLevel()# 7闯关方法def nextLevel(self):MainGame.score += 20MainGame.remnant_score -= 20for i in range(1, 100):if MainGame.score == 100 * i and MainGame.remnant_score == 0:MainGame.remnant_score = 100 * iMainGame.shaoguan += 1MainGame.produce_zombie += 50def display_peabullet(self):MainGame.window.blit(self.image, self.rect)

20. 僵尸类

class Zombie(pygame.sprite.Sprite):def __init__(self, x, y):super(Zombie, self).__init__()self.image = pygame.image.load('imgs/zombie.png')self.rect = self.image.get_rect()self.rect.x = xself.rect.y = yself.hp = 1000self.damage = 2self.speed = 1self.live = Trueself.stop = False# 9 僵尸的移动def move_zombie(self):if self.live and not self.stop:self.rect.x -= self.speedif self.rect.x < -80:# 8 调用游戏结束方法MainGame().gameOver()# 9 判断僵尸是否碰撞到植物，如果碰撞，调用攻击植物的方法def hit_plant(self):for plant in MainGame.plants_list:if pygame.sprite.collide_rect(self, plant):# 8  僵尸移动状态的修改self.stop = Trueself.eat_plant(plant)# 9 僵尸攻击植物def eat_plant(self, plant):# 9 植物生命值减少plant.hp -= self.damage# 9 植物死亡后的状态修改，以及地图状态的修改if plant.hp <= 0:a = plant.rect.y // 80 - 1b = plant.rect.x // 80map = MainGame.map_list[a][b]map.can_grow = Trueplant.live = False# 8 修改僵尸的移动状态self.stop = False# 9 将僵尸加载到地图中def display_zombie(self):MainGame.window.blit(self.image, self.rect)

21. 主程序

class MainGame():# 2 创建关数，得分，剩余分数，钱数shaoguan = 1score = 0remnant_score = 100money = 200# 3 存储所有地图坐标点map_points_list = []# 3 存储所有的地图块map_list = []# 4 存储所有植物的列表plants_list = []# 7 存储所有豌豆子弹的列表peabullet_list = []# 9 新增存储所有僵尸的列表zombie_list = []count_zombie = 0produce_zombie = 100# 1 加载游戏窗口def init_window(self):# 1 调用显示模块的初始化pygame.display.init()# 1 创建窗口MainGame.window = pygame.display.set_mode([scrrr_width, scrrr_height])# 2 文本绘制def draw_text(self, content, size, color):pygame.font.init()font = pygame.font.SysFont('kaiti', size)text = font.render(content, True, color)return text# 2 加载帮助提示def load_help_text(self):text1 = self.draw_text('1.按左键创建向日葵 2.按右键创建豌豆射手', 26, (255, 0, 0))MainGame.window.blit(text1, (5, 5))# 3 初始化坐标点def init_plant_points(self):for y in range(1, 7):points = []for x in range(10):point = (x, y)points.append(point)MainGame.map_points_list.append(points)print("MainGame.map_points_list", MainGame.map_points_list)# 3 初始化地图def init_map(self):for points in MainGame.map_points_list:temp_map_list = list()for point in points:# map = Noneif (point[0] + point[1]) % 2 == 0:map = Map(point[0] * 80, point[1] * 80, 0)else:map = Map(point[0] * 80, point[1] * 80, 1)# 将地图块加入到窗口中temp_map_list.append(map)print("temp_map_list", temp_map_list)MainGame.map_list.append(temp_map_list)print("MainGame.map_list", MainGame.map_list)# 3 将地图加载到窗口中def load_map(self):for temp_map_list in MainGame.map_list:for map in temp_map_list:map.load_map()# 6 增加豌豆射手发射处理def load_plants(self):for plant in MainGame.plants_list:# 6 优化加载植物的处理逻辑if plant.live:if isinstance(plant, Sunflower):plant.display_sunflower()plant.produce_money()elif isinstance(plant, PeaShooter):plant.display_peashooter()plant.shot()else:MainGame.plants_list.remove(plant)# 7 加载所有子弹的方法def load_peabullets(self):for b in MainGame.peabullet_list:if b.live:b.display_peabullet()b.move_bullet()# v1.9 调用子弹是否打中僵尸的方法b.hit_zombie()else:MainGame.peabullet_list.remove(b)# 8事件处理def deal_events(self):# 8 获取所有事件eventList = pygame.event.get()# 8 遍历事件列表，判断for e in eventList:if e.type == pygame.QUIT:self.gameOver()elif e.type == pygame.MOUSEBUTTONDOWN:# print('按下鼠标按键')print(e.pos)# print(e.button)#左键1  按下滚轮2 上转滚轮为4 下转滚轮为5  右键 3x = e.pos[0] // 80y = e.pos[1] // 80print(x, y)map = MainGame.map_list[y - 1][x]print(map.position)# 8 增加创建时候的地图装填判断以及金钱判断if e.button == 1:if map.can_grow and MainGame.money >= 50:sunflower = Sunflower(map.position[0], map.position[1])MainGame.plants_list.append(sunflower)print('当前植物列表长度:{}'.format(len(MainGame.plants_list)))map.can_grow = FalseMainGame.money -= 50elif e.button == 3:if map.can_grow and MainGame.money >= 50:peashooter = PeaShooter(map.position[0], map.position[1])MainGame.plants_list.append(peashooter)print('当前植物列表长度:{}'.format(len(MainGame.plants_list)))map.can_grow = FalseMainGame.money -= 50# 9 新增初始化僵尸的方法def init_zombies(self):for i in range(1, 7):dis = random.randint(1, 5) * 200zombie = Zombie(800 + dis, i * 80)MainGame.zombie_list.append(zombie)# 9将所有僵尸加载到地图中def load_zombies(self):for zombie in MainGame.zombie_list:if zombie.live:zombie.display_zombie()zombie.move_zombie()# v2.0 调用是否碰撞到植物的方法zombie.hit_plant()else:MainGame.zombie_list.remove(zombie)# 1 开始游戏def start_game(self):# 1 初始化窗口self.init_window()# 3 初始化坐标和地图self.init_plant_points()self.init_map()# 9 调用初始化僵尸的方法self.init_zombies()# 1 只要游戏没结束，就一直循环while not GAMEOVER:# 1 渲染白色背景MainGame.window.fill((255, 255, 255))# 2 渲染的文字和坐标位置MainGame.window.blit(self.draw_text('当前钱数$: {}'.format(MainGame.money), 26, (255, 0, 0)), (500, 40))MainGame.window.blit(self.draw_text('当前关数{}，得分{},距离下关还差{}分'.format(MainGame.shaoguan,MainGame.score,MainGame.remnant_score),26,(255,0,0)),(5,40))self.load_help_text()# 3 需要反复加载地图self.load_map()# 6 调用加载植物的方法self.load_plants()# 7  调用加载所有子弹的方法self.load_peabullets()# 8 调用事件处理的方法self.deal_events()# 9 调用展示僵尸的方法self.load_zombies()# 9 计数器增长，每数到100，调用初始化僵尸的方法MainGame.count_zombie += 1if MainGame.count_zombie == MainGame.produce_zombie:self.init_zombies()MainGame.count_zombie = 0pygame.time.wait(10)pygame.display.update()def gameOver(self):MainGame.window.blit(self.draw_text('游戏结束', 50, (255, 0, 0)), (300, 200))print('游戏结束')pygame.time.wait(400)global GAMEOVERGAMEOVER = Trueif __name__ == '__main__':game = MainGame()game.start_game()

运行效果图就是这样的啦
