爲什麼我的while循環中的任何if語句都不起作用？

-2

我做了一個while循環和.blit（）工作正常，但是當它到達if語句時，我的加載符號出現，似乎沒有任何工作。我正在做我的while循環嗎？我也希望我的menu1 == False觸發下一個while循環。爲什麼我的while循環中的任何if語句都不起作用？

'menu1 == False'是一個比較，評估爲'False'爲'True！= False'，** not **一個任務。你也可以「打破」。 – jonrsharpe

遊戲的每個狀態（菜單，選項，遊戲，幫助等）都應該有自己的循環幷包含：** 1 **。保持恆定幀速率的時鐘。 ** 2 **。事件循環。 ** 3 **。更新對象。 ** 4 **。 Blit /繪製物體。 ** ** 5。更新顯示。 [Here]（http://stackoverflow.com/documentation/pygame/3959/getting-started-with-pygame/14697/a-simple-game#t=201702041456298336222）是一個簡單的演練。 –

也許你需要'如果menu1 == True'而不是'while menu1 == True'。你也可以將它分成獨立的循環：http://imgur.com/MT7tZ4s – furas

你需要

=而不是==在menu1 = False
if menu1 == True，而不是while menu1 == True

但是你可以更好地組織代碼（或使用了分離mainloop菜單，遊戲和h ELP）。
