前言
本篇文章主要分享如何添加向前移动的小动物作为动态的障碍物，一个是飞行障碍物主角可以通过滑行躲避，另一个是爬行障碍物可以通过跳跃躲避。
一、添加小动物素材
1. 在根目录的图片文件夹下新建两个目录分别存放爬行障碍物和飞行障碍物。
2. 图片示例
二、代码部分
1.创建飞行小动物的精灵类
python
import pygame.sprite
class Badman(pygame.sprite.Sprite):
def __init__(self):
super(Badman,self).__init__()
self.image=pygame.image.load('material/image/badman/badman3.1.PNG').convert_alpha()
self.images=[pygame.image.load('material/image/badman/badman3.{:d}.png'.format(i)).convert_alpha() for i in range(1,6)]
self.rect = self.images[0].get_rect()
self.loc = 500
self.speed = 1
def update(self, *args):
if args[0] % 10 == 0:
i = int(args[0] / 10)
self.image = self.images[i % len(self.images)]
if self.rect.left < 0:
self.kill()
else:
self.rect.left -= self.speed1.创建爬行小动物的精灵类
代码如下：
python

import pygame.sprite
class mantis(pygame.sprite.Sprite):
def __init__(self):
super(mantis,self).__init__()
self.image=pygame.image.load('material/image/mantis/b5.1.PNG').convert_alpha()
self.images=[pygame.image.load('material/image/mantis/b5.{:d}.png'.format(i)).convert_alpha() for i in range(1,16)]
self.rect = self.images[0].get_rect()
self.loc=500
self.speed = 1
self.rect.left = 770
def update(self, *args):
if args[0] % 10 == 0:
i = int(args[0] / 10)
self.image=self.images[i%len(self.images)]
if self.rect.left<0:
self.kill()
else:
self.rect.left -= self.speed3.在左半部分按随机数添加飞行或者爬行
代码如下：
c
if left<=-1080:
left=left+2160
random_number = random.randint(1, 2)
if random_number == 1:
badman=Badman()
badman.rect.top = 360
enemyGroup.add(badman)
if random_number == 2:
enemyone = mantis()
enemyone.rect.top = 440
enemyGroup.add(enemyone)
if -1080<left<1080:
for sprite in enemyGroup:
sprite.rect.left=sprite.loc+left*1.5
if pygame.sprite.collide_mask(sprite, myself):
injure = pygame.mixer.Sound('material/music/injure1.mp3')
pygame.mixer.Sound.play(injure)
myself.life -= 1
sprite.kill()
enemyGroup.draw(screen)
enemyGroup.update(index)4.runner_main的全部代码
