运行效果

1.引入需要的模块，配置图片路径，设置界面，创建游戏主入口。

#1 引入需要的模块
import os
import time

import pygame
import random
#1 配置图片地址
IMAGE_PATH = 'imgs/'

scrrr_width=800
scrrr_height =560
GAMEOVER = False
#1主程序
class MainGame():
    def init_window(self):
        pygame.display.init()
        #1创建窗口
        MainGame.window = pygame.display.set_mode([scrrr_width,scrrr_height])  
    #1开始游戏
    def start_game(self):
        #1初始化窗口
        self.init_window()
        #1只要游戏没结束，就一直循环
        while not GAMEOVER:
           
            MainGame.window.fill((255, 255, 255))
           
            pygame.display.update()
#1启动主程序
if __name__ == '__main__':
    game = MainGame()
    game.start_game()

2.文本绘制，创建属性

shaoguan = 1
score = 0
remnant_score = 100
money = 200
#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('按左键种植太阳  按右键种植豌豆射手', 26, (255, 0, 0))
    MainGame.window.blit(text1, (150, 30))

3.创建地图类，初始化地图和坐标

地图类 包含了游戏中草坪的相关信息，例如当前单元格是否允许种植。

#3 创建地图类
class Map():

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

    def __init__(self, x, y, img_index):
        self.image = pygame.image.load(Map.map_names_list[img_index])
        self.position = (x, y)
        pygame.display.set_caption("植物大战僵尸")

        self.can_grow = True

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

                if (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)

                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()

4.创建植物类

定义了植物相关属性和方法，目前只包含太阳和豌豆两个子类。

LOG = '文件:中的方法:出错'.format(__file__,__name__)
def getFileRealPath(fileName):
    return os.path.join(os.path.dirname(__file__), fileName)
#4 植物类
class Plant(pygame.sprite.Sprite):
    def __init__(self):
        super(Plant, self).__init__()
        self.live=True


    def load_image(self):
        if hasattr(self, 'image') and hasattr(self, 'rect'):
            MainGame.window.blit(self.image, self.rect)
        else:
            print(LOG)
#4 存储所有植物的列表
plants_list = []

5.创建太阳类

#5 太阳类
class Sunflower(Plant):
    def __init__(self,x,y):
        super(Sunflower, self).__init__()
        self.image = pygame.image.load(getFileRealPath('imgs/sunflower.png'))
        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = y
        self.price = 50
        self.hp = 100

        self.time_count = 0

    #5 新增功能：生成阳光
    def produce_money(self):
        self.time_count += 1

        if self.time_count == 25:
            MainGame.money += 5
            self.time_count = 0

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

6.创建豌豆射手类

#6 豌豆射手类
class PeaShooter(Plant):
    def __init__(self,x,y):
        super(PeaShooter, self).__init__()

        self.image = pygame.image.load(getFileRealPath('imgs/peashooter.png'))
        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = y
        self.price = 50
        self.hp = 200
        #6 发射计数器
        self.shot_count = 0

    #6 增加射击方法
    def shot(self):

        should_fire = False
        for 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

        if self.live and should_fire:
            self.shot_count += 1

            if self.shot_count == 25:

                peabullet = PeaBullet(self)

                MainGame.peabullet_list.append(peabullet)
                self.shot_count = 0

    #6 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)
        
	#6 增加豌豆射手发射处理
    def load_plants(self):
        for plant in MainGame.plants_list:

            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.创建子弹类

定义了豌豆子弹的相关属性和方法，包括飞行、打击等，杀死僵尸、得分闯关在这里定义。

#7 豌豆子弹类
class PeaBullet(pygame.sprite.Sprite):
    def __init__(self,peashooter):
        self.live = True
        self.image = pygame.image.load(getFileRealPath('imgs/peabullet.png'))
        self.damage = 50
        self.speed  = 10
        self.rect = self.image.get_rect()
        self.rect.x = peashooter.rect.x + 60
        self.rect.y = peashooter.rect.y + 15

    def move_bullet(self):

        if self.rect.x < scrrr_width:
            self.rect.x += self.speed
        else:
            self.live = False


    def hit_zombie(self):
        for zombie in MainGame.zombie_list:
            if pygame.sprite.collide_rect(self,zombie):

                self.live = False

                zombie.hp -= self.damage
                if zombie.hp <= 0:
                    zombie.live = False
                    self.nextLevel()
	#7闯关方法
    def nextLevel(self):
        MainGame.score += 20
        MainGame.remnant_score -=20
        for i in range(1,100):
            if MainGame.score==100*i and MainGame.remnant_score==0:
                    MainGame.remnant_score=100*i
                    MainGame.shaoguan+=1
                    MainGame.produce_zombie+=50



    def display_peabullet(self):
        MainGame.window.blit(self.image,self.rect)
	peabullet_list = []

	#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()

                b.hit_zombie()
            else:
                MainGame.peabullet_list.remove(b)
	#7  调用加载所有子弹的方法
    self.load_peabullets()

8.事件处理

#8事件处理
    def deal_events(self):
        eventList = pygame.event.get()
        for e in eventList:
            if e.type == pygame.QUIT:
                self.gameOver()
            elif e.type == pygame.MOUSEBUTTONDOWN:
                print(e.pos)
                x = e.pos[0] // 80
                y = e.pos[1] // 80
                print(x, y)
                map = MainGame.map_list[y - 1][x]
                print(map.position)

                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 = False
                        MainGame.money -= 50
                elif 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 = False
                        MainGame.money -= 50
                        
                        #8 调用事件处理的方法
                    	self.deal_events()

deal_events方法，这是游戏中的事件处理方法，玩家的所有操作都需要在这里得到响应。

9.创建僵尸类

定义了僵尸的属性和方法，包括移动和攻击等，游戏失败条件（僵尸穿越条件）也在这里定义。

#9 僵尸类
class Zombie(pygame.sprite.Sprite):
    def __init__(self,x,y):
        super(Zombie, self).__init__()
        self.image = pygame.image.load(getFileRealPath('imgs/zombie.png'))
        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = y
        self.hp = 800
        self.damage = 2
        self.speed = 1
        self.live = True
        self.stop = False

    def move_zombie(self):
        if self.live and not self.stop:
            self.rect.x -= self.speed
            if self.rect.x < -80:
                #8 调用游戏结束方法
                MainGame().gameOver()


    def hit_plant(self):
        for plant in MainGame.plants_list:
            if pygame.sprite.collide_rect(self,plant):

                self.stop = True
                self.eat_plant(plant)

    def eat_plant(self,plant):

        plant.hp -= self.damage

        if plant.hp <= 0:
            a = plant.rect.y // 80 - 1
            b = plant.rect.x // 80
            map = MainGame.map_list[a][b]
            map.can_grow = True
            plant.live = False

            self.stop = False


    def display_zombie(self):
        MainGame.window.blit(self.image,self.rect)
    #9 新增存储所有僵尸的列表   
	zombie_list = []
    count_zombie = 0
    produce_zombie = 100

	    def init_zombies(self):
        for i in range(1, 7):
            dis = random.randint(1, 5) * 200
            zombie = Zombie(800 + dis, i * 80)
            MainGame.zombie_list.append(zombie)


    def load_zombies(self):
        for zombie in MainGame.zombie_list:
            if zombie.live:
                zombie.display_zombie()
                zombie.move_zombie()

                zombie.hit_plant()
            else:
                MainGame.zombie_list.remove(zombie)
	#9 调用初始化僵尸的方法
        self.init_zombies()
        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 += 1
        if MainGame.count_zombie == MainGame.produce_zombie:
            self.init_zombies()
            MainGame.count_zombie = 0
        
        pygame.time.wait(10) 
#1 实时更新
        pygame.display.update()

10.游戏结束方法

#10 程序结束方法
    def gameOver(self):
        MainGame.window.blit(self.draw_text('僵尸吃掉了你的脑子', 50, (255, 0, 0)), (300, 200))

        pygame.time.wait(100)
        global GAMEOVER
        GAMEOVER = True
