1.引入需要的模块，配置图片路径，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 = None
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)
# 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
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 = x
self.rect.y = y
self.price = 50
self.hp = 100
#5 时间计数器
self.time_count = 0
#5 功能：生成阳光（生产钱）
def produce_money(self):
self.time_count += 1
if self.time_count == 25:
MainGame.money += 5
self.time_count = 0
#5 向日葵加入到窗口中
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 为一个 surface
self.image = pygame.image.load('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):
#6 记录是否应该射击
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
#6 如果活着
if self.live and should_fire:
self.shot_count += 1
# 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
#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:
#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)
#6 调用加载植物的方法
self.load_plants()
7.创建子弹类
#7 豌豆子弹类
class PeaBullet(pygame.sprite.Sprite):
def __init__(self,peashooter):
self.live = True
self.image = pygame.image.load('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):
#7 在屏幕范围内，实现往右移动
if self.rect.x < scrrr_width:
self.rect.x += self.speed
else:
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.
