植物大战僵尸

---

1. 引入需要的模块，配置图片的路径,设置界面宽高背景颜色。创建游戏主入口

#1引入需要的模块
import pygame
import random
#1配置图片地址
IMAGE_PATH = 'imgs/'#1设置页面宽高
scrrr_width=800
scrrr_height =560#1创建控制游戏结束的状态
GAMEOVER = False#1主程序class MainGame():#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])  ##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:#1渲染白色背景MainGame.window.fill((255, 255, 255))#1实时更新pygame.display.update()
#1启动主程序
if __name__ == '__main__':game = MainGame()game.start_game()

2. 文本绘制，创建要动态改变的属性，渲染的位置

#2 创建关数，得分，剩余分数，钱数
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('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))#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. 创建地图类，初始化地图和坐标

#3 创建地图类
class Map():#3 存储两张不同颜色的图片名称map_names_list = [IMAGE_PATH + 'map1.png', IMAGE_PATH + 'map2.png']#3 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)# 是否能够种植self.can_grow = True#3 加载地图def load_map(self):MainGame.window.blit(self.image,self.position)#3 存储所有地图坐标点map_points_list = []#3 存储所有的地图块map_list = []#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()#3 初始化坐标和地图self.init_plant_points()self.init_map()#3 需要反复加载地图self.load_map()

4. 创建植物类，图片加载报错处理，加载植物方法

#4 图片加载报错处理
LOG = '文件:{}中的方法:{}出错'.format(__file__,__name__)
#4 植物类
class Plant(pygame.sprite.Sprite):def __init__(self):super(Plant, self).__init__()self.live=True# 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)#4 存储所有植物的列表
plants_list = []

5.创建向日葵类

#5 向日葵类
