為什么我的文本被復制而不是包裝在 pygame 中？

Question

我正在用 pygame 編寫一個基本的基於文​​本的游戲（我不是很有經驗，這是我的第一個問題），我從類文檔字符串的兩頁中按順序對字母進行了自動換行和動畫處理並排序的結合他們。 現在，文本動畫，但如果有一個單詞應該開始一個新行，它不會換行並且表現得像第二個附件中的那樣（在新行上重復）。 不知道在網上搜索什么。 蟒蛇3.8.5； pygame 2.1.2。

它對一行的作用（正確）

它對應該包裝的文本有什么作用（不正確）

您應該從這個問題中鏈接的第一個問題添加分行。 除了你可以使用這樣的東西：

body = ['Be careful with your inputs, game does not have good error handling!',
                'To choose who begins the game input "a" for computer or "b" for yourself',
                'Press enter to play']
        label = []
        for line in range(len(body)):
            label.append(word_font.render(body[line], True, yellow)) #creates text lable

        for line in range(len(label)):
            disp.blit(label[line], [display_w / 5, 150 + 25 * line]) #positions the text
