用Python制作小游戏之‘植物大战僵尸’（一）

1.引入需要的模块

import pygame
import random

2.配置图片地址及页面宽高等

IMAGE_PATH = 'D:\桌面\练习\python\植物大战僵尸\imgs'
scrrr_width = 800
scrrr_height = 560
# 1 创建控制游戏结束的状态
GAMEOVER = False
# 4 图片加载报错处理
LOG = '文件:{}中的方法:{}出错'.format(__file__, __name__)

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']

    def __init__(self, x, y, img_index):
        self.image = pygame.image.load(Map.map_names_list[img_index])
        self.position = (x, y)
        self.can_grow = True

    # 3 加载地图
    def load_map(self):
        MainGame.window.blit(self.image, self.position)

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)


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
        self.time_count = 0

5.增加射击方法

    def shot(self):
        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:

7.豌豆子弹

class PeaBullet(pygame.sprite.Sprite):
    def __init__(self, peashooter):
        self.live = True
        self.image = pygame.image.load('imgs/peabullet.png')
        self.damage = 50
        self.speed = 10
        self.rect = self.image.get_rect()
        self.rect.x = peashooter.rect.x + 60
        self.rect.y = peashooter.rect.y + 15

8.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.以及主程序部分

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])

    # 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

    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)
    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()

10.启动程序

if __name__ == '__main__':
    game = MainGame()
    game.start_game()
