等待输入后继续-Arduino Uno

Question

我正在使用Arduino Uno制作基本的体育比赛得分手（壁球/壁球）。

目标是2个按钮，每个玩家1个按钮都有一个按钮，可以用来提高得分。
这很简单，但是如果＆当两个玩家同时碰到10分时，他们需要选择进入13或15。

我的问题是，它在调用scoreDecide()函数之前正在监听最后按下的按钮。

例如，player1位于9（向左按钮）上，player2位于10（向右按钮）上。

player1按下其左键最多将其带到10， scoreDecide()被自动调用为循环，因为它是10/10 [score]。

player2决定按右键，选择15作为得分，但是实际上已经选择了左键值，因为这是在调用scoreDecide()函数之前最后一次按下的值，这意味着实际上是将13设置为target ，然后按了右键实际上是在增加player2的得分。

我的代码如下，到目前为止，我已经花费了8个小时，但是我是Arduino的新手，所以没有运气。
