上次写了一个俄罗斯方块,感觉好像大家都看懂了,这次就更新一个植物大战僵尸吧
植物大战僵尸的话

引入需要的模块
import pygame import random
配置图片地址
IMAGE_PATH = 'imgs/'
设置页面宽高
scrrr_width = 800 scrrr_height = 560
创建控制游戏结束的状态
GAMEOVER = False
图片加载报错处理
LOG = '文件:{}中的方法:{}出错'.format(__file__, __name__)
创建地图类
class Map():
存储两张不同颜色的图片名称
map_names_list = [IMAGE_PATH + 'map1.png', IMAGE_PATH + 'map2.png']
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
加载地图
def load_map(self): MainGame.window.blit(self.image, self.position)
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)
向日葵类
class Sunflower(Plant): def __init__(self, x, y): super(Sunflower, 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
新增功能:生成阳光
def produce_money(self): self.time_count += 1 if self.time_count == 25:
MainGame.money += 5 self.time_count = 0
向日葵加入到窗口中
def display_sunflower(self): MainGame.window.blit(self.image, self.rect)
豌豆射手类
class PeaShooter(Plant): def __init__(self, x, y): super(PeaShooter, self).

rect.y = y self.price = 50 self.hp = 200 # 6 发射计数器 self.shot_count = 0
增加射击方法

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 # 6 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.

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

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 <= 0: a = plant.rect.y // 80 - 1 b = plant.rect
.x // 80 map = MainGame.map_list[a][b] map.can_grow = True plant.live = False #
8 修改僵尸的移动状态 self.stop = False # 9 将僵尸加载到地图中 def display_zombie(self): MainGame.
window.blit(self.image, self.rect)
