用pygame学习初级python（二） 15.5.11
闲得无聊，对第一版的东西做了一些修改，让它更像一个游戏，也具有一些可玩性。项目的github地址： https://github.com/lfkdsk/BrainHole_pygame
1.人物类进行了一些修改，添加了怪物类的生成机制：

首先，初始化了屏幕的大小，并且设置了图片资源。
1 class Enemy(pygame.sprite.Sprite):
2 def __init__(self, init_pos):
3 pygame.sprite.Sprite.__init__(self)
4 self.image = pygame.image.load("resources/image/zm-2.png")
5 self.rect = self.image.get_rect()
6 self.rect.topleft = init_pos
7 self.speed = 2
8 self.down_index = 0
9 self.walk = 0
10
11 def move(self):
12 topleft = self.rect.topleft
13 if self.walk > 40:
14 self.walk = 0
15 self.image = pygame.image.load("resources/image/zm-2.png")
16 if self.walk == 20:
17 self.image = pygame.image.load("resources/image/zm-1.png")
18 self.rect = self.image.get_rect()
19 self.rect.topleft = topleft
20 self.walk += 1
21 self.rect.centerx -= self.speed
怪物类设置了一个move函数，在初始化里设定了一个walk的值，能让在自增的过程中，不断的切换图片。
就是这样的两张图片。
1 class Bullet(pygame.sprite.Sprite):
2 def __init__(self, init_pos):
3 pygame.sprite.Sprite.__init__(self)
4 self.image = pygame.image.load('resources/image/bullet.png')
5 self.rect = self.image.get_rect()
6 self.rect.midtop = init_pos
7 self.speed = 10
8 self.walk = 0
9
10 def move(self, button_flag):
11 if button_flag == 1:
12 self.rect.centerx -= self.speed
13 elif button_flag == 0:
14 self.rect.centerx += self.speed
15 elif button_flag == 2:
16 self.rect.centery += self.speed
17 elif button_flag == 3:
18 self.rect.centery -= self.speed
子弹类添加了在不同移动方向上的不同移动方法，可以向左右两个方向发射。
（发射飞剑！）
1 class Player(pygame.sprite.Sprite):
2 def __init__(self):
3 pygame.sprite.Sprite.__init__(self)
4 self.image = pygame.image.load('resources/image/down-1.png')

17 if distance == 2:

20 self.image = pygame.image.load(Player_image_down)
21 self.rect = self.image.get_rect()
22 self.rect.center = center
23 self.down += 1
24 # screen.blit(player.image, player.rect)
25 elif distance == 0:
26 if self.left > 3:
27 self.left = 0
28 self.image = pygame.image.load(Player_image_left)
29 self.rect = self.image.get_rect()

44 self.rect.center = center
45 self.right += 1
46
47 def move(self, temper):
48 temper = int(temper)
49 if temper == 0:
50 for temp in range(1, 10):
51 self.rect.centerx -= 3
52 print self.rect.centerx, self.rect.centery
53 if temper == 1:
54 self.rect.centerx += self.speed
55 print self.rect.centery
56 if temper == 2:
57 self.rect.centery -= self.speed
58 print self.rect.centerx, self.rect.centery
59 if temper == 3:

64 self.rect.centery = -self.rect.centery
65
66 def shoot(self):
67 bullet = Bullet(self.rect.midtop)
68 Bullets.append(bullet)
修改了turn函数让图片不断切换的，在字符数组里不断的进行切换图片，做出人物（李逍遥）走路的样子。
（利用图片的反复切换）

注释里写的很详细了哦，这次改完之后会出现可随按键移动的子弹类似飞剑的效果哦！
好了第二篇就是这样，喜欢就点赞吧，=-=！
