如何從文本文件顯示文本到pygame屏幕上？

我試圖從pygame屏幕中的文本文件顯示遊戲說明。在這一點上，我已經編碼：如何從文本文件顯示文本到pygame屏幕上？

def instructions(): 
    screen.fill(TEAL) 
    with open("pongInstructions.txt", encoding = 'utf-8') as f: 
     for line in f: 
      instructText = instructionsFont.render(line, True, WHITE) 
      screen.blit(instructText, ((400 - (instructText.get_width()/2)),(300 - (instructText.get_height()/2)))) 
      pygame.display.update()

當我呼籲說明功能，什麼也沒有發生。有人有一個想法，爲什麼？任何幫助是極大的讚賞！

就快，但需要screen.blit矩形對象旁邊的textsprite，這個對象是用來定義精靈的大小和位置。此外，您需要給每條線自己設置x或y座標（否則它們將全部繪製在彼此之上）解決此問題的一種方法是使用for n, line in enumerate(f)這將爲您提供每行的索引值，稱爲n 。如果用枚舉並刪除當前screen.blit發言，並與該塊替換它應該工作：

text_rect = instructText.get_rect() 
    text_rect.centerx = SCREENSIZE[0]//2 
    text_rect.centery = n*25 + 50 
    screen.blit(text, text_rect)

在這裏您可以通過調用它的get_rect()方法獲取文本精靈一個矩形對象，然後設置其中心x座標作爲屏幕的中心（我使用容器來保持屏幕尺寸），然後將其中心y座標設置爲25 *陣列中的線位置+ 50像素的填充，最後將其繪製到屏幕上，並使用screen.blit(text, text_rect)

我做了一個使用自定義字體的實例，你可以看到它here

在以前的項目，我也做了這樣的任務，這個對象，歡迎您使用或複製它，如果你願意，你可以找到它here

不管怎麼說，我希望它的幫助下，快樂編碼。

編輯：

剛接手在你的代碼，並從我可以看到你的代碼，目前什麼也不做:) 您在sartscreen（）函數定義你想要的行爲，但從來沒有調用的函數，因此沒有發生，這是你的主要思想，幸運的是它是一個簡單的解決方案，只需在你的文檔底部調用函數就可以了。startscreen(screen)

但是等一下？你會注意到我已經添加了屏幕對象到這個函數調用中，這是因爲你需要把你的函數作爲屏幕對象的引用，否則它不知道你在說什麼「屏幕對象」，你需要用任何使用屏幕對象的函數來做到這一點，但是你也需要告訴你的函數期望一個參數，所以當你定義你的startscreen函數和指令函數時，你也需要像這樣添加屏幕對象def startscreen(screen):和def instructions(screen):現在你的函數知道你在說什麼叫screen.fill(COLOR)和screen.blit(text, text_rect)

除此之外，它只是一個小的細節問題時什麼，但應用這兩個更改後您的菜單似乎爲我工作的蟒蛇3.5，不過我建議你看看Clock object以及限制你的幀率（否則遊戲將在超級計算機上運行速度超快）

我已將你的代碼合併到我的主代碼中，但它仍然不顯示。這可能是我放置代碼的地方存在的一個問題 - 就像我在一個單獨的文件中運行它時一樣完美。你介意檢查一下嗎？我在原始帖子中添加了一部分代碼作爲修改。非常感謝你的幫助！ – Student

我看了你的代碼並編輯了我的初始答案，評論太長了，我試着在應用上述兩個修復程序後運行你的代碼，現在它似乎正在工作。 – Molex4

Ahah我確實調用了函數，但這只是我的代碼的一部分 - 具有指令功能的部分，這就是爲什麼它看起來不完整但非常感謝。不過，我的整個菜單都起作用，它只是指示部分，而不是。如果您想看到它，我已經添加了我的整個代碼，因爲它似乎仍然沒有提示說明。 – Student

如何從文本文件顯示文本到pygame屏幕上？
