创建 Sprite

# ……

# 初始Pygame及窗口
# ……

class Player(pygame.sprite.Sprite):
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.Surface((50, 50))
        self.image.fill(GREEN)
        self.rect = self.image.get_rect()
        self.rect.center = (WIDTH / 2, HEIGHT / 2)

# 主循环
#……
all_sprites = pygame.sprite.Group()
player = Player()
all_sprites.add(player)
while running:
#  ……

Sprite 移动 sprite 精灵的矩形区域 rect

# ……
class Player(pygame.sprite.Sprite):
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.Surface((50, 50))
        self.image.fill(GREEN)
        self.rect = self.image.get_rect()
        self.rect.center = (WIDTH / 2, HEIGHT / 2)

    def update(self):
        self.rect.x += 5
        if self.rect.left > WIDTH:
            self.rect.right = 0

主循环添加，调用Sprit 更新函数 Update

# 主循环
running = True
while running:
    # ...

    # 更新内容
    all_sprites.update()

    # 填充背景色
    screen.fill(BLACK)
    # 绘制所有精灵
    all_sprites.draw(screen)
    # 刷新
    pygame.display.flip()

pygame.quit()
