上一篇中，我們已經(jīng)畫出了棋盤，那這一篇呢，我們就一起來看看如何在棋盤上繪制棋子~~~

寫前準(zhǔn)備，下載一套字體，先來看看下面的代碼：

#畫‘悔棋’，‘重新開始’和‘退出’按鈕
    #定義按鍵顏色
    button_color = (163,80,21)

    #繪制三個矩形來做按鍵
    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)
    #調(diào)用包，導(dǎo)入字體
    s_font = pygame.font.Font('anjian_font.ttf',45)
    #打印字體
    text1 = s_font.render("悔    棋",True,button_color)
    text2 = s_font.render("重新開始",True,button_color)
    text3 = s_font.render("退出游戲",True,button_color)
    screen.blit(text1,(1000,320))
    screen.blit(text2,(980,520))
    screen.blit(text3,(980,720))

上面這段代碼呢，就已經(jīng)告訴了你字體的用法，意圖呢，就是打印出你想打印的字體，下面打印象棋的棋子時我們還會用到這個方法，關(guān)于字體詳細(xì)的介紹，大家去博客搜，相關(guān)篇幅很多，在此我就不再多說，下面，我們進(jìn)入正題：

細(xì)心的你可能已經(jīng)發(fā)現(xiàn)了，沒錯，我在這里已經(jīng)把繪制棋盤和繪制棋子合并成了一個總函數(shù)，先繪制棋盤，再繪制棋子，為什么要總呢？讀懂了繪制棋子的函數(shù)你就懂了，棋子是一個一個畫的，也就是說執(zhí)行一次繪制棋子的函數(shù)，就畫出一個棋子，難道我們要執(zhí)行32次繪制棋子的函數(shù)？另外，后面你下一步棋，棋子就會更新一遍，那得畫多少遍？

來看看執(zhí)行效果：

順便說下，如果要應(yīng)用這段代碼，怎么辦呢？認(rèn)真看過前面的博文的朋友都知道，對啦，下載一套字體，用你下載的字體命名替換此文章中的字體命名，或者直接把你下載的字體命名為此文章中的字體命名就OK了，當(dāng)然，前提是在同一文件夾下，哦，不要忘了，還有前面的‘楚河漢界’喲！

好了，今天的博文就到這里啦，是不是有點(diǎn)樣子了呢？下一篇博客，我們就讓棋子跑起來~~~

文章中有任何不懂的問題，歡迎大家騷擾，博主很愿意和大家共同進(jìn)步喲，整理不易，喜歡的話就打賞一下吧~~~
