大家好,我是 A梦。
今天给大家带来一个 Python 的练手项目。用Python的Pygame游戏开发库编写代码写一个植物大战僵尸!
直接开搞!
1. 引入需要的模块
import pygame
import random
2. 配置图片地址
IMAGE_PATH = 'imgs/'
3. 设置页面宽高
scrrr_width = 800
scrrr_height = 560
4. 创建控制游戏结束的状态
GAMEOVER = False
5. 图片加载报错处理
LOG = '文件:{}中的方法:{}出错'.format(__file__, __name__)
6. 创建地图类
class Map():
7. 存储两张不同颜色的图片名称
map_names_list = [IMAGE_PATH + 'map1.png', IMAGE_PATH + 'map2.png']
8. 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)
9. 是否能够种植
self.can_grow = True
10. 加载地图
def load_map(self):
MainGame.window.blit(self.image, self.position)
11. 植物类
class Plant(pygame.sprite.Sprite):
def __init__(self):
super(Plant, self).__init__()
self.live = True
12. 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)
13. 向日葵类
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 = x
self.rect.y = y
self.price = 50
self.hp = 100
# 5 时间计数器
self.time_count = 0
14. 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
15. 向日葵加入到窗口中
def display_sunflower(self):
MainGame.window.blit(self.image, self.rect)
16. 豌豆射手类
class PeaShooter(Plant):
def __init__(self, x, y):

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

# 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:

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.peabullet_list.append(peabullet)
self.shot_count = 0
18. 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)
19. 豌豆子弹类

运行效果图就是这样的啦
