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 pygameimport random#1配置图片地址IMAGE_PATH = 'imgs/'#1设置页面宽高scrrr_width=800scrrr_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 = 1score = 0remnant_score = 100money = 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 = []

[code]#9 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 = x self.rect.y = y self.hp = 1000 self.damage = 2 self.speed = 1 self.live = True self.stop = False #9 僵尸的移动 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() #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 = True self.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 |
