上一篇中，我们已经画出了棋盘，那这一篇呢，我们就一起来看看如何在棋盘上绘制棋子~~~
写前准备，下载一套字体，先来看看下面的代码：
#画‘悔棋’，‘重新开始’和‘退出’按钮#定义按键颜色button_color = (163,80,21)#绘制三个矩形来做按键pygame.draw.rect(screen,button_color,[980,300,200,100],5)pygame.draw.rect(screen,button_color,[980,500,200,100],5)pygame.draw.rect(screen,button_color,[980,700,200,100],5)#调用包，导入字体s_font = pygame.font.Font('anjian_font.ttf',45)#打印字体text1 = s_font.render("悔 棋",True,button_color)text2 = s_font.render("重新开始",True,button_color)text3 = s_font.render("退出游戏",True,button_color)screen.blit(text1,(1000,320))screen.blit(text2,(980,520))screen.blit(text3,(980,720))
上面这段代码呢，就已经告诉了你字体的用法，意图呢，就是打印出你想打印的字体，下面打印象棋的棋子时我们还会用到这个方法，关于字体详细的介绍，大家去博客搜，相关篇幅很多，在此我就不再多说，下面，我们进入正题：

细心的你可能已经发现了，没错，我在这里已经把绘制棋盘和绘制棋子合并成了一个总函数，先绘制棋盘，再绘制棋子，为什么要总呢？读懂了绘制棋子的函数你就懂了，棋子是一个一个画的，也就是说执行一次绘制棋子的函数，就画出一个棋子，难道我们要执行32次绘制棋子的函数？另外，后面你下一步棋，棋子就会更新一遍，那得画多少遍？
来看看执行效果：
顺便说下，如果要应用这段代码，怎么办呢？认真看过前面的博文的朋友都知道，对啦，下载一套字体，用你下载的字体命名替换此文章中的字体命名，或者直接把你下载的字体命名为此文章中的字体命名就OK了，当然，前提是在同一文件夹下，哦，不要忘了，还有前面的‘楚河汉界’哟！
好了，今天的博文就到这里啦，是不是有点样子了呢？下一篇博客，我们就让棋子跑起来~~~
文章中有任何不懂的问题，欢迎大家骚扰，博主很愿意和大家共同进步哟~~~
