为什么每个玩家的积分都在重新分配？

Question

我的记分跟踪器是把两个球员的分数重新分配到原来的号码，每次我都这么做不止一次。

我不明白为什么每当我从任何一个玩家那里夺走更多的生命值，而不是使用之前的生命点数，它只是重置到我所做的任何生命点开始和从那里。

例:玩家-1有100个生命点。我拿走了一个生命点。玩家-1现在有99个生命点。现在我又做了一次。我又夺去了1号玩家的生命点。但是现在，不是从以前的生命点数99中取1，而是从100再取1，第二次给我99分。

我不知道我在哪里犯了一个错误，一直在重新计算分数。

Answer 1

您从不更改storage_1/2值。

像display_2 = storage_2 - ch_2;这样的线将继续用生命点的原始数目(100)计算差额，而不是从先前计算的数量中减去。在计算storage_x值之后尝试更新这些display_x值。
