爲什麼每個玩家的積分都會重置？

Question

我的點數跟蹤器每次重複執行時，都會將兩位玩家的分數重設爲原始數字。

我不知道爲什麼每當我從任一玩家身上拿走更多的生命值而不是使用之前的生命點數時，它就會重置爲我所做的任何生命點的開始和結束在那裏形成。

EX： 玩家-1擁有100點生命值。 我拿走了1個生命點。玩家1現在有99個生命點。 現在我再做一次。 我從玩家1中奪走了1個生命值。 但是現在，它不是從先前的99點生命點數中拿走1點，而是從100點再次離開1點，並且第二次給了我99點。

我不知道我在哪裏犯了一個錯誤，不斷重新設置分數。

Answer 1

您永遠不會更改storage_1/2值。

像display_2 = storage_2 - ch_2;這樣的一行將繼續計算與原始生命點數（100）的差值，而不是從先前計算的金額中減去。在計算display_x值後，請嘗試更新這些storage_x值。
