大家好,今天给大家下面给大家分享用 Python 实现植物大战僵尸的案例,喜欢记得收藏、点赞、关注。
文末提供源码分享,尽情去玩吧。
下面是部分代码实现逻辑,完整版代码,文末获取
1.引入需要的模块,配置图片路径,设置界面宽高背景颜色,创建游戏主入口。
import pygame
import random
IMAGE_PATH = 'imgs/'
scrrr_width=800
scrrr_height =560
GAMEOVER = False
class MainGame():
def init_window(self):
pygame.display.init()
MainGame.window = pygame.display.set_mode([scrrr_width,scrrr_height])
def start_game(self):
self.init_window()
while not GAMEOVER:
MainGame.window.fill((255, 255, 255))
pygame.display.update()
if __name__ == '__main__':
game = MainGame()
game.start_game()
2.文本绘制,创建要动态改变的属性,渲染的位置
shaoguan = 1
score = 0
remnant_score = 100
money = 200
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 load_help_text(self):
text1 = self.draw_text('1.按左键创建向日葵 2.按右键创建豌豆射手', 26, (255, 0, 0))
MainGame.window.blit(text1, (5, 5))
MainGame.window.blit(self.draw_text('当前钱数$: {}'.format(MainGame.money), 26, (255, 0, 0)), (500, 40))
MainGame.window.blit(self.draw_text(
'当前关数{},得分{},距离下关还差{}分'.format(MainGame.shaoguan, MainGame.score, MainGame.remnant_score), 26,
(255, 0, 0)), (5, 40))
self.load_help_text()
3.创建地图类,初始化地图和坐标**
class Map():
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
def load_map(self):
MainGame.window.blit(self.image,self.position)
map_points_list = []
map_list = []
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:
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)
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)
def load_map(self):
for temp_map_list in MainGame.map_list:
for map in temp_map_list:
map.load_map()
self.init_plant_points()
self.init_map()
self.load_map()
4.创建植物类,图片加载报错处理,加载植物方法
LOG = '文件:{}中的方法:{}出错'.format(__file__,__name__)
class Plant(pygame.sprite.Sprite):
def __init__(self):
super(Plant, self).__init__()
self.live=True
def load_image(self):
if hasattr(self, 'image') and hasattr(self, 'rect'):
MainGame.window.blit(self.image, self.rect)
else:
print(LOG)
plants_list = []5.创建向日葵类
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
self.time_count = 0
def produce_money(self):
self.time_count += 1
if self.time_count == 25:
MainGame.money += 5
self.time_count = 0
def display_sunflower(self):
MainGame.window.blit(self.image,self.rect)
5.创建豌豆射手类
class PeaShooter(Plant):
def __init__(self,x,y):
super(PeaShooter, self).__init__()
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
self.shot_count = 0
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
if self.live and should_fire:
self.shot_count += 1
if self.shot_count == 25:
peabullet = PeaBullet(self)
MainGame.peabullet_list.append(peabullet)
self.shot_count = 0
def display_peashooter(self):
MainGame.window.blit(self.image,self.rect)
def load_plants(self):
for plant in MainGame.plants_list:
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)
self.load_plants()
6.创建子弹类
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
def move_bullet(self):
if self.rect.x < scrrr_width:
self.rect.x += self.speed
else:
self.live = False
def hit_zombie(self):
for zombie in MainGame.zombie_list:
if pygame.sprite.collide_rect(self,zombie):
self.live = False
zombie.hp -= self.damage
if zombie.hp <= 0:
zombie.live = False
self.nextLevel()
def nextLevel(self):
MainGame.score += 20
MainGame.remnant_score -=20
for i in range(1,100):
if MainGame.score==100*i and MainGame.remnant_score==0:
MainGame.remnant_score=100*i
MainGame.shaoguan+=1
MainGame.produce_zombie+=50
def display_peabullet(self):
MainGame.window.blit(self.image,self.rect)
peabullet_list = []
def load_peabullets(self):
for b in MainGame.peabullet_list:
if b.live:
b.display_peabullet()
b.move_bullet()
b.hit_zombie()
else:
MainGame.peabullet_list.remove(b)
self.load_peabullets()
7.创建僵尸类
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
def move_zombie(self):
if self.live and not self.stop:
self.rect.x -= self.speed
if self.rect.x < -80:
MainGame().gameOver()
def hit_plant(self):
for plant in MainGame.plants_list:
if pygame.sprite.collide_rect(self,plant):
self.stop = True
self.eat_plant(plant)
def eat_plant(self,plant):
plant.hp -= self.damage
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
self.stop = False
def display_zombie(self):
MainGame.window.blit(self.image,self.rect)
zombie_list = []
count_zombie = 0
produce_zombie = 100
def init_zombies(self):
for i in range(1, 7):
dis = random.randint(1, 5) * 200
zombie = Zombie(800 + dis, i * 80)
MainGame.zombie_list.append(zombie)
def load_zombies(self):
for zombie in MainGame.zombie_list:
if zombie.live:
zombie.display_zombie()
zombie.move_zombie()
zombie.hit_plant()
else:
MainGame.zombie_list.remove(zombie)
self.init_zombies()
self.load_zombies()
MainGame.count_zombie += 1
if MainGame.count_zombie == MainGame.produce_zombie:
self.init_zombies()
MainGame.count_zombie = 0
pygame.time.wait(10)
8.游戏结束方法
def gameOver(self):
MainGame.window.blit(self.draw_text('游戏结束', 50, (255, 0, 0)), (300, 200))
pygame.time.wait(400)
global GAMEOVER
GAMEOVER = True
