在继续之前等待输入- Arduino Uno

Question

我正在做一个基本的体育游戏得分手(壁球/赛车)使用一个阿迪诺尤诺。

目标是，两个按钮，每个玩家有一个按钮，他们可以用它来增加分数。

这是很简单的，然而，如果&当两个球员碰巧同时得到10分，他们需要选择要么到13分，要么15分。

我的问题是，在调用scoreDecide()功能之前，它正在监听最后一个按钮。

player1在9(左键)，player2在10(右键)。

player1按下他们的左键，把他们带到10，scoreDecide()自动被称为循环识别这是10分。

player2决定按右键，选择15作为分数，但实际上它已经选择了左边按钮的值，因为这是调用scoreDecide() func之前最后一次按下按钮，这意味着13实际上被设置为target，而按右按钮实际上是在增加玩家2的分数。

我的代码如下所示，到目前为止，我已经花了8个小时，但我对Arduino完全是新手，没有运气。

我成功地解决了这个问题，把逻辑分为两部分，一是启动答案，二是等待答案的输入，如果有人感兴趣的话：

            // For this reason we need to include logic to let the players choose what score to play until, always in either incremenets of 2 || 4. EG: 13 || 15, 17 || 19 etc.
