大家好，我正在创建一个使用 4x4 2Darray 的记忆游戏。
我用 0-7 的一对整数填充了 4x4，它们是随机分散的。我想为每一对分配一种颜色，因此当鼠标单击该方块时，分配的颜色将基于整数出现，您必须根据其对应的匹配颜色找到另一个整数。我的这个 setColor 方法遇到了一些问题。我将包含我的整个代码，以防我在其他地方搞砸了，这就是原因。目前，如果我使用了两次分配的所有 8 种颜色一次单击每个方块，但某些颜色与另一个图块上相同整数的位置不匹配。此外，当我多次单击同一个图块时，它会在 2-3 种颜色之间变化，我不确定我做错了什么。
我需要建议的部分是我分配的 setColor 方法及其背后的逻辑。
