開發思路

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主程序 class MainGame():#1加載游戲窗口def init_window(self):#1調用顯示模塊的初始化pygame.display.init()#1創建窗口MainGame.window = pygame.display.set_mode([scrrr_width,scrrr_height]) ##1開始游戲def start_game(self):#1初始化窗口self.init_window()#1只要游戲沒結束，就一直循環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啟動主程序 if __name__ == '__main__':game = MainGame()game.start_game()

2.文本繪制，創建要動態改變的屬性，渲染的位置

#2 創建關數，得分，剩余分數，錢數 shaoguan = 1 score = 0 remnant_score = 100 money = 200 #2 文本繪制 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 加載幫助提示 def load_help_text(self):text1 = self.draw_text('1.按左鍵創建向日葵 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 存儲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 存儲所有地圖坐標點map_points_list = []#3 存儲所有的地圖塊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 = 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)# 將地圖塊加入到窗口中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 將地圖加載到窗口中def load_map(self):for temp_map_list in MainGame.map_list:for map in temp_map_list:map.load_map()#3 初始化坐標和地圖self.init_plant_points()self.init_map()#3 需要反復加載地圖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 = '文件:{}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 存儲所有植物的列表 plants_list = []

5.創建向日葵類

#5 向日葵類 class Sunflower(Plant):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 = xself.rect.y = yself.price = 50self.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 += 1if self.time_count == 25:MainGame.money += 5self.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.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 surfaceself.image = pygame.image.load('imgs/peashooter.png')self.rect = self.image.get_rect()self.rect.x = xself.rect.y = yself.price = 50self.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 = Falsefor 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 基于當前豌豆射手的位置，創建子彈peabullet = PeaBullet(self)#6 將子彈存儲到子彈列表中MainGame.peabullet_list.append(peabullet)self.shot_count = 0#6 將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)#6 調用加載植物的方法self.load_plants()

7.創建子彈類

#7 豌豆子彈類 class PeaBullet(pygame.sprite.Sprite):def __init__(self,peashooter):self.live = Trueself.image = pygame.image.load('imgs/peabullet.png')self.damage = 50self.speed = 10self.rect = self.image.get_rect()self.rect.x = peashooter.rect.x + 60self.rect.y = peashooter.rect.y + 15def move_bullet(self):#7 在屏幕范圍內，實現往右移動if self.rect.x < scrrr_width:self.rect.x += self.speedelse:self.live = False#7 新增，子彈與僵尸的碰撞def hit_zombie(self):for zombie in MainGame.zombie_list:if pygame.sprite.collide_rect(self,zombie):#打中僵尸之后，修改子彈的狀態，self.live = False#僵尸掉血zombie.hp -= self.damageif zombie.hp <= 0:zombie.live = Falseself.nextLevel()#7闖關方法def nextLevel(self):MainGame.score += 20MainGame.remnant_score -=20for i in range(1,100):if MainGame.score==100*i and MainGame.remnant_score==0:MainGame.remnant_score=100*iMainGame.shaoguan+=1MainGame.produce_zombie+=50def display_peabullet(self):MainGame.window.blit(self.image,self.rect)#7 存儲所有豌豆子彈的列表peabullet_list = []#7 加載所有子彈的方法 def load_peabullets(self):for b in MainGame.peabullet_list:if b.live:b.display_peabullet()b.move_bullet()#7 調用子彈是否打中僵尸的方法b.hit_zombie()else:MainGame.peabullet_list.remove(b)#7 調用加載所有子彈的方法self.load_peabullets()

8.事件處理``

#8事件處理def deal_events(self):#8 獲取所有事件eventList = pygame.event.get()#8 遍歷事件列表，判斷for e in eventList:if e.type == pygame.QUIT:self.gameOver()elif e.type == pygame.MOUSEBUTTONDOWN:# print('按下鼠標按鍵')print(e.pos)# print(e.button)#左鍵1 按下滾輪2 上轉滾輪為4 下轉滾輪為5 右鍵 3x = e.pos[0] // 80y = e.pos[1] // 80print(x, y)map = MainGame.map_list[y - 1][x]print(map.position)#8 增加創建時候的地圖裝填判斷以及金錢判斷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('當前植物列表長度:{}'.format(len(MainGame.plants_list)))map.can_grow = FalseMainGame.money -= 50elif 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('當前植物列表長度:{}'.format(len(MainGame.plants_list)))map.can_grow = FalseMainGame.money -= 50#8 調用事件處理的方法self.deal_events()

9.創建僵尸類

#9 僵尸類 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 = xself.rect.y = yself.hp = 1000self.damage = 2self.speed = 1self.live = Trueself.stop = False#9 僵尸的移動def move_zombie(self):if self.live and not self.stop:self.rect.x -= self.speedif self.rect.x < -80:#8 調用游戲結束方法MainGame().gameOver()#9 判斷僵尸是否碰撞到植物，如果碰撞，調用攻擊植物的方法def hit_plant(self):for plant in MainGame.plants_list:if pygame.sprite.collide_rect(self,plant):#8 僵尸移動狀態的修改self.stop = Trueself.eat_plant(plant)#9 僵尸攻擊植物def eat_plant(self,plant):#9 植物生命值減少plant.hp -= self.damage#9 植物死亡后的狀態修改，以及地圖狀態的修改if plant.hp <= 0:a = plant.rect.y // 80 - 1b = plant.rect.x // 80map = MainGame.map_list[a][b]map.can_grow = Trueplant.live = False#8 修改僵尸的移動狀態self.stop = False#9 將僵尸加載到地圖中def display_zombie(self):MainGame.window.blit(self.image,self.rect)#9 新增存儲所有僵尸的列表zombie_list = []count_zombie = 0produce_zombie = 100 #9 新增初始化僵尸的方法def init_zombies(self):for i in range(1, 7):dis = random.randint(1, 5) * 200zombie = Zombie(800 + dis, i * 80)MainGame.zombie_list.append(zombie)#9將所有僵尸加載到地圖中def load_zombies(self):for zombie in MainGame.zombie_list:if zombie.live:zombie.display_zombie()zombie.move_zombie()# v2.0 調用是否碰撞到植物的方法zombie.hit_plant()else:MainGame.zombie_list.remove(zombie)#9 調用初始化僵尸的方法self.init_zombies()#9 調用展示僵尸的方法self.load_zombies()#9 計數器增長，每數到100，調用初始化僵尸的方法MainGame.count_zombie += 1if MainGame.count_zombie == MainGame.produce_zombie:self.init_zombies()MainGame.count_zombie = 0#9 pygame自己的休眠pygame.time.wait(10)

10.游戲結束方法

#10 程序結束方法 ----------------------------------------------------- 注：我這有個學習基地，里面有很多學習資料，感興趣的+Q群：895817687 ----------------------------------------------------- def gameOver(self):MainGame.window.blit(self.draw_text('游戲結束', 50, (255, 0, 0)), (300, 200))pygame.time.wait(400)global GAMEOVERGAMEOVER = True
