如何在類def中每x時間做x

Question

你如何每 x 次做 x 次。 我試圖在我的代碼中，市政廳類使用def函數add_money每50秒添加一次錢（這是被稱為城市類的一部分），但我在查找或執行代碼時遇到了麻煩，我認為你可以使用時間.sleep() 但這不起作用，因為它減慢了我的代碼，我該如何在不妨礙主事件代碼或類 def 的情況下做到這一點？

Answer 1

首先，您應該為幀數和游戲時間設置一些常量變量。 然后在你的加錢方法中，你會發生一些事情。 一：將幀計數加一，因為該方法在游戲循環的每次迭代中都會調用一次。 二：檢查幀數除以您的 FPS 是否等於 0，邏輯如下： if frame_count % FPS == 0:然后在此 if 語句中，添加游戲時間並將幀數設置回零。 然后你將有一個每秒計數的變量。 最后，您可以像這樣檢查游戲時間： if game_time % 50 == 0:並添加到您所在城市的現金供應中，最后將游戲時間設置回 0，因為您的其他代碼都不依賴於計時器。
