當我的暫停在pygame中播放我的game_loop函數時，如何阻止我的遊戲重新啓動？

Question

所以，我正在pygame上製作一個簡單的視頻遊戲，它非常接近完成。我在暫停屏幕上工作，但是當我點擊p（我選擇的按鈕）時，它暫停了，但當我繼續時，它重新開始遊戲。我檢查了代碼，發現沒有錯。然後，我去了這裏的問題論壇，查找了這個問題，我發現了一些東西，但他們並沒有像我一樣執行代碼，除此之外，答案很難理解。暫停功能是paused()，取消暫停功能是，unpause()。你可以嘗試找出它出錯的地方嗎？這裏是我的scource代碼：

Answer 1

在我的代碼，我取消暫停按鈕功能設置爲game_loop()，而不是unpause()。所以每次我去取消暫停，我重新開始遊戲循環！這是一個例子，你必須注意你的代碼的每一部分，而不僅僅是那些出錯的函數。

Answer 2

看來你並沒有在你的pause()函數中取消暫停。

你應該加入這樣的事：

def paused(): 
    while pause: 
     for event in pygame.event.get(): 
      if event.type == pygame.QUIT: 
       pygame.quit() 
       quit() 
      if event.type == pygame.K_p: 
       unpause()
