注：截止到2020年07月23日，PyGame 1.9.6版本在macOS上无法显示图片等，改用2.0.0.dev10后显示正常
使用PyGame可以很方便的制作小游戏，快速支持手柄操作、键盘鼠标操作以及动画实现、物体绘制。

初始化游戏基本设置
- 初始化
pygame、pygame.joystick.init()、clock帧率

| # GAME BASIC CONFIG
pygame.init()
pygame.joystick.init()
joysticks = [pygame.joystick.Joystick(x) for x in range(pygame.joystick.get_count())]
clock = pygame.time.Clock()

定义窗口

| # WINDOW
screen_size = screen_width, screen_height = [600, 600]
screen = pygame.display.set_mode(screen_size)
pygame.display.set_caption("cat movement")
done = False

定义物体、背景
- 可用
get_rect方法获取物体大小
- 使用
pygame.transform.scale重新定义物体分辨率

object_cat = pygame.transform.scale(object_cat, (200, 200))
position = object_cat.get_rect()
# object_cat_width = object_cat.get_width()
# object_cat_height = object_cat.get_height()
# object_cat_x = screen_width / 2 - object_cat_width / 2
# object_cat_y = screen_height - object_cat_height
# PROPERTY CAT ENDED
# PROPERTY BG
img_bg = image.load("bg.jpg")
screen.blit(img_bg, (0, 0))
# PROPERTY BG END

初始化事务Event
- 此处实现手柄控制物体移动
- 使用
position.move完成物体移动
- 使用
screen.blit方法放置物体，display.update()更新窗口
- 使用
pygame.event.get()获取当前事务
