Python粽子
Love And Program 人气:1粽子和爱心制作
PS截取小爱心和我最爱的咸粽子
建立两个精灵并搭建背景元素
粽子和爱心
先是建立一个粽子对象,也就是一个精灵,类里面需要继承pygame.sprite.Sprite
类,这是碰撞模块的重要部分。update
函数是控制粽子方向,并防止粽子跑出边界,当粽子触碰到边界时出发触底反弹功能,使粽子向边界另一方向反弹移动。
class Player(pygame.sprite.Sprite): """ 粽子对象 """ def __init__(self): pygame.sprite.Sprite.__init__(self) self.image = pygame.image.load('min2.png') self.image = pygame.transform.scale(self.image, (130, 130)) print(self.image) self.rect = self.image.get_rect() self.rect.midbottom = (20, screen_height ) def update(self): screen.blit(self.image, (self.rect.x, self.rect.y)) screen.blit(self.image, self.rect) x_move = 0 y_move = 0 # 获取按键,并进行相应的移动 key = pygame.key.get_pressed() #通过控制数字来设置粽子速度 if key[pygame.K_LEFT]: x_move -= 4 if key[pygame.K_RIGHT]: x_move += 4 if key[pygame.K_UP]: y_move -= 4 if key[pygame.K_DOWN]: y_move += 4 self.rect.x += x_move self.rect.y += y_move # 控制人物的最低位置 if self.rect.bottom > screen_height+330 : self.rect.bottom = screen_height + 330 # 绘制粽子 screen.blit(self.image, self.rect) #防止粽子跑出边界 if self.rect.right > 1400: self.rect.x -= 20 elif self.rect.left <=-10: self.rect.x += 20 elif self.rect.top < 0: self.rect.y += 50 elif self.rect.bottom> 730: self.rect.y -= 60
在添加一个❤,当咸粽吃到❤时得分。其也必须继承pygame.sprite.Sprite
类,通过Move_update
使❤随机出现在游戏中,并在游戏边界内移动。
class Heart_game(pygame.sprite.Sprite): def __init__(self): pygame.sprite.Sprite.__init__(self) self.Heart_speed = [2,-3] # 加载小球图片 self.image = pygame.image.load('min_love.png').convert_alpha() # 获取小球图片的区域开状 self.rect = self.image.get_rect() x,y = random.randint(0,1300),random.randint(0,700) self.active = True self.rect.midbottom = (x, y ) def Move_update(self): self.rect = self.rect.move(self.Heart_speed) #绘制爱心图片 screen.blit(self.image, self.rect) if self.rect.right > 1400: x = random.randint(-5, 0) y = random.randint(-5, -2) or random.randint(1, 5) self.Heart_speed = [x, y] elif self.rect.left <=-10: x = random.randint(0, 5) y = random.randint(-5, 5) self.Heart_speed = [x, y] elif self.rect.top < -10: x = random.randint(-3,3) y = random.randint(0,3) self.Heart_speed = [x,y] elif self.rect.bottom> 695: x = random.randint(-3, 3) y = random.randint(-3,0) self.Heart_speed = [x, y]
注 意 : \color{#FF45b0}{注意:} 注意:screen.blit(image, rect)
为在游戏中绘制图片,必须包含两个参数,一个是图片本身,另一个是图片在游戏中的位置,即为rect
。
背景搭建
直接导入图片并在循环中显示
bg = pygame.image.load("vack.jpeg").convert() #下句需在游戏主循环中使用 screen.blit(bg, (0, 0))
搭建完成后为
碰撞模块
碰撞部分我可是煞费苦心啊,使用以下语句, 尤 其 是 ! ! \color{blue}{尤其是!!} 尤其是!!我一开始以为没有碰撞,添加多个语句,实际上他发生了,只是我没有加语句->在此条件下会发生什么,造成这个惨案…
我们来好好分析这段条件,player
是粽子对象,group
是一个包含❤的组,pygame.sprite.collide_circle_ratio(0.5)
可以控制图片碰撞体积,于是碰撞条件达成!
if pygame.sprite.spritecollide(player,group,True,pygame.sprite.collide_circle_ratio(0.5)) : 语句
贪吃模块
当达到碰撞时把❤吃掉,设l
为一个空数组,用l.append(aixin)
加入❤实例,当数组l
存在时,进入碰撞环节,碰撞后用pop
函数删除❤。
然后加入判断,若数组l为空,则新加入❤游戏实例,也就是上述❤实例
for each in l: each.Move_update() screen.blit(each.image, each.rect) if pygame.sprite.spritecollide(player,group,True,pygame.sprite.collide_circle_ratio(0.5)) : l.pop() score += 1 print(score) # del aixin if not l: l.append(Heart_game()) group.add(l[0])
计数机制
用score
计算,引用一个ttf
字体文件
score = 0 score_font = pygame.font.Font("font.ttf",50) score_text = score_font.render("Score: % s" % str(score), True, BLACK) screen.blit(score_text, (0, 0))
