前言

本篇主要实现移动距离的计算，以及按键指引的添加

---

一、创建字体文件夹

1.可以从网上自行下载中文字体存入当前文件夹下

默认字体可能不支持中文，因此需要确保系统中有支持中文的字体，并尝试通过字体名称指定

2.将计算距离以及按键的图片素材放入对应的目录内

二、代码部分

1.初始化图片和文字

代码如下：

#距离图
km_image_path= 'material/image/km.png'
km_img_obj=pygame.image.load(km_image_path).convert_alpha()
#按键图
keyUp_image_path= 'material/image/keyboardUpUp.png'
keyUp_img_obj=pygame.image.load(keyUp_image_path).convert_alpha()
keyLeft_image_path= 'material/image/keyboardLEFT.png'
keyLeft_img_obj=pygame.image.load(keyLeft_image_path).convert_alpha()
keyDown_image_path= 'material/image/keyboardDown.png'
keyDown_img_obj=pygame.image.load(keyDown_image_path).convert_alpha()
font_path = 'material/ziti/AlimamaFangYuanTiVF-Thin-2.ttf'  # 例如 'SimSun.ttf'
chinese_font = pygame.font.Font(font_path, 30)
text_surface = chinese_font.render('跳跃', True, (0, 0, 255))
text1_surface = chinese_font.render('疾跑', True, (0, 0, 255))
text2_surface = chinese_font.render('滑行', True, (0, 0, 255))

2.屏幕中贴入图片，并将距离按照每6次时钟增加十米更新

代码如下：

#键位介绍
screen.blit(keyUp_img_obj, (900, 5))
screen.blit(text_surface, (980, 23))
screen.blit(keyLeft_img_obj, (900, 70))
screen.blit(text1_surface, (980, 88))
screen.blit(keyDown_img_obj, (900, 135))
screen.blit(text2_surface, (980, 148))
#路程
screen.blit(km_img_obj, (10, 70))
km_font = pygame.font.SysFont('arial', 30)
km_num_surface = km_font.render(km, True, (0, 0, 255))
screen.blit(km_num_surface, (80, 88))
if index%6==0:km = str(int(km) + margin)
