這是一款常見的街機游戲，目標是盡可能多地擊中所有目標以獲得最高分。每次球擊中“石頭”，您將獲得 1 分，如果擊中 2，您將分別獲得 2 分。如果球員未能在橫桿或“桿”上接球，則比賽結束。
我的任務是將這個用面向物件編程撰寫的游戲變成函式式編程。

uj5u.com熱心網友回復：
在將這個用面向物件編程撰寫的游戲轉變為函式式編程的程序中，我們需要處理每個函式正在使用的變數/小部件。如果我們正在對本地函式中的某個變數進行更改，并希望在函式呼叫結束后保留??所做的更改，那么我將使這些變數/小部件成為全域的。
此外，在 OOP 代碼中，每次都在畫布中使用draw()“球”和“桿”的函式進行更改。drawB()因此為相同的和創建兩個函式drawP()：

您可以進一步優化此代碼。
