覺得還OK的話,點下Star,作者不易,thank you!

 

1.引入需要的模塊,配置圖片路徑,設置界面寬高背景顏色,創建游戲主入口。

#1引入需要的模塊
import pygame
import random
#1配置圖片地址
IMAGE_PATH = 'imgs/'
#1設置頁面寬高
scrrr_width=800
scrrr_height =560
#1創建控制游戲結束的狀態
GAMEOVER = False
#1主程式
class MainGame():
     #1加載游戲視窗
    def init_window(self):
        #1呼叫顯示模塊的初始化
        pygame.display.init()
        #1創建視窗
        MainGame.window = pygame.display.set_mode([scrrr_width,scrrr_height])  #
    #1開始游戲
    def start_game(self):
        #1初始化視窗
        self.init_window()
        #1只要游戲沒結束,就一直迴圈
        while not GAMEOVER:
            #1渲染白色背景
            MainGame.window.fill((255, 255, 255))
            #1實時更新
            pygame.display.update()
#1啟動主程式
if __name__ == '__main__':
    game = MainGame()
    game.start_game()

2.文本繪製,創建要動態改變的屬性,渲染的位置

#2 創建關數,得分,剩餘分數,錢數
shaoguan = 1
score = 0
remnant_score = 100
money = 200
#2 文本繪製
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 加載幫助提示
def load_help_text(self):
    text1 = self.draw_text('1.按左鍵創建嚮日葵 2.按右鍵創建豌豆射手', 26, (255, 0, 0))
    MainGame.window.blit(text1, (5, 5))

#2 渲染的文字和坐標位置
        MainGame.window.blit(self.draw_text('當前錢數$: {}'.format(MainGame.money), 26, (255, 0, 0)), (500, 40))
        MainGame.window.blit(self.draw_text(
            '當前關數{},得分{},距離下關還差{}分'.format(MainGame.shaoguan, MainGame.score, MainGame.remnant_score), 26,
            (255, 0, 0)), (5, 40))
        self.load_help_text()

3.創建地圖類,初始化地圖和坐標

#3 創建地圖類
class Map():
    #3 儲存兩張不同顏色的圖片名稱
    map_names_list = [IMAGE_PATH + 'map1.png', IMAGE_PATH + 'map2.png']
    #3 初始化地圖
    def __init__(self, x, y, img_index):
        self.image = pygame.image.load(Map.map_names_list[img_index])
        self.position = (x, y)
        # 是否能夠種植
        self.can_grow = True
    #3 加載地圖
    def load_map(self):
         MainGame.window.blit(self.image,self.position)

    #3 儲存所有地圖坐標點
    map_points_list = []
    #3 儲存所有的地圖塊
    map_list = []

    #3 初始化坐標點
    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 初始化地圖
    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)
                # 將地圖塊加入到視窗中
                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 將地圖加載到視窗中
    def load_map(self):
        for temp_map_list in MainGame.map_list:
            for map in temp_map_list:
                map.load_map()

    #3 初始化坐標和地圖
    self.init_plant_points()
    self.init_map()

    #3 需要反覆加載地圖
    self.load_map()

4.創建植物類,圖片加載報錯處理,加載植物方法

#4 圖片加載報錯處理
LOG = '檔案:{}中的方法:{}出錯'.format(__file__,__name__)
#4 植物類
class Plant(pygame.sprite.Sprite):
    def __init__(self):
        super(Plant, self).__init__()
        self.live=True

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

#4 儲存所有植物的串列
plants_list = []

5.創建嚮日葵類

#5 嚮日葵類

    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 時間計數器
        self.time_count = 0

    #5 功能:生成陽光(生產錢)
    def produce_money(self):
        self.time_count += 1
        if self.time_count == 25:
            MainGame.money += 5
            self.time_count = 0
    #5 嚮日葵加入到視窗中
    def display_sunflower(self):
        MainGame.window.blit(self.image,self.rect)

6.創建豌豆射手類

    #6 豌豆射手類
class PeaShooter(Plant):
    def __init__(self,x,y):
        super(PeaShooter, self).__init__()
        # self.image 為一個 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 發射計數器
        self.shot_count = 0

    #6 增加射擊方法
    def shot(self):
        #6 記錄是否應該射擊
        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 如果活著
        if self.live and should_fire:
            self.shot_count += 1
            # 計數器到25發射一次
            if self.shot_count == 25:
                #6 基於當前豌豆射手的位置,創建子彈
                peabullet = PeaBullet(self)
                #6 將子彈儲存到子彈串列中
                MainGame.peabullet_list.append(peabullet)
                self.shot_count = 0

    #6 將豌豆射手加入到視窗中的方法
    def display_peashooter(self):
        MainGame.window.blit(self.image,self.rect)

    #6 增加豌豆射手發射處理
    def load_plants(self):
        for plant in MainGame.plants_list:
            #6 優化加載植物的處理邏輯
            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)
