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_pygame1.人物类进行了一些修改，添加了怪物类的生成机制：

1 __author__ = 'Administrator' 2 import pygame 3 4 Window_width = 1365 5 Window_height = 768 6 screen = pygame.display.set_mode((Window_width, Window_height)) 7 first_location = [screen.get_width() / 2, screen.get_height() / 2] 8 Player_image_up = ['resources/image/up-1.png', 'resources/image/up-2.png', 'resources/image/up-3.png', 9 'resources/image/up-4.png'] 10 Player_image_down = ['resources/image/down-1.png', 'resources/image/down-2.png', 'resources/image/down-3.png', 11 'resources/image/down-4.png'] 12 Player_image_left = ['resources/image/left-1.png', 'resources/image/left-2.png', 'resources/image/left-3.png', 13 'resources/image/left-4.png'] 14 Player_image_right = ['resources/image/right-1.png', 'resources/image/right-2.png', 'resources/image/right-3.png', 15 'resources/image/right-4.png'] 16 Enemy_image = ["resources/image/zm-1.png", "resources/image/zm-2.png"] 17 Bullets = []
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') 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 = 0 10 self.left = 0 11 self.right = 0 12 self.up = 0 13 # print self.rect.center 14 15 def turn(self, distance): 16 center = self.rect.center 17 if distance == 2: 18 if self.down > 3: 19 self.down = 0 20 self.image = pygame.image.load(Player_image_down[self.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[self.left]) 29 self.rect = self.image.get_rect() 30 self.rect.center = center 31 self.left += 1 32 elif distance == 3: 33 if self.up > 3: 34 self.up = 0 35 self.image = pygame.image.load(Player_image_up[self.up]) 36 self.rect = self.image.get_rect() 37 self.rect.center = center 38 self.up += 1 39 elif distance == 1: 40 if self.right > 3: 41 self.right = 0 42 self.image = pygame.image.load(Player_image_right[self.right]) 43 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: 60 self.rect.centery += self.speed 61 if 0 > self.rect.centerx or self.rect.centerx > screen.get_width(): 62 self.rect.centerx = -self.rect.centerx 63 if 0 > self.rect.centery or self.rect.centery > screen.get_height(): 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）
2.主函数体的修改：

（死亡的界面）
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，=-=！
