　　閑得無聊，對第一版的東西做了一些修改，讓它更像一個(gè)游戲，也具有一些可玩性。

1.人物類進(jìn)行了一些修改，添加了怪物類的生成機(jī)制：

首先，初始化了屏幕的大小，并且設(shè)置了圖片資源。

 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 = 010 11     def move(self):12         topleft = self.rect.topleft13         if self.walk > 40:14             self.walk = 015             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 = topleft20         self.walk += 121         self.rect.centerx -= self.speed

怪物類設(shè)置了一個(gè)move函數(shù)，在初始化里設(shè)定了一個(gè)walk的值，能讓在自增的過程中，不斷的切換圖片。

就是這樣的兩張圖片。

 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.speed13         elif button_flag == 0:14             self.rect.centerx += self.speed15         elif button_flag == 2:16             self.rect.centery += self.speed17         elif button_flag == 3:18             self.rect.centery -= self.speed

子彈類添加了在不同移動方向上的不同移動方法，可以向左右兩個(gè)方向發(fā)射。

（發(fā)射飛劍！）

 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') 5         self.rect = self.image.get_rect() 6         self.rect.center = first_location 7         self.is_hit = False 8         self.speed = 15 9         self.down = 010         self.left = 011         self.right = 012         self.up = 013         # print self.rect.center14 15     def turn(self, distance):16         center = self.rect.center17         if distance == 2:18             if self.down > 3:19                 self.down = 020             self.image = pygame.image.load(Player_image_down[self.down])21             self.rect = self.image.get_rect()22             self.rect.center = center23             self.down += 124             # screen.blit(player.image, player.rect)25         elif distance == 0:26             if self.left > 3:27                 self.left = 028             self.image = pygame.image.load(Player_image_left[self.left])29             self.rect = self.image.get_rect()30             self.rect.center = center31             self.left += 132         elif distance == 3:33             if self.up > 3:34                 self.up = 035             self.image = pygame.image.load(Player_image_up[self.up])36             self.rect = self.image.get_rect()37             self.rect.center = center38             self.up += 139         elif distance == 1:40             if self.right > 3:41                 self.right = 042             self.image = pygame.image.load(Player_image_right[self.right])43             self.rect = self.image.get_rect()44             self.rect.center = center45             self.right += 146 47     def move(self, temper):48         temper = int(temper)49         if temper == 0:50             for temp in range(1, 10):51                 self.rect.centerx -= 352             print self.rect.centerx, self.rect.centery53         if temper == 1:54             self.rect.centerx += self.speed55             print self.rect.centery56         if temper == 2:57             self.rect.centery -= self.speed58             print self.rect.centerx, self.rect.centery59         if temper == 3:60             self.rect.centery += self.speed61         if 0 > self.rect.centerx or self.rect.centerx > screen.get_width():62             self.rect.centerx = -self.rect.centerx63         if 0 > self.rect.centery or self.rect.centery > screen.get_height():64             self.rect.centery = -self.rect.centery65 66     def shoot(self):67         bullet = Bullet(self.rect.midtop)68         Bullets.append(bullet)

修改了turn函數(shù)讓圖片不斷切換的，在字符數(shù)組里不斷的進(jìn)行切換圖片，做出人物（李逍遙）走路的樣子。

（利用圖片的反復(fù)切換）
