试图让球从数组组件中反弹回来?(想不出更好的词)C#.

我有一个球根据需要从桨和墙壁上弹起，然后我通过抽奖添加了一块奇异的砖块。矩形工具，让球从中反弹，然后改变其颜色，但无法使其不可见以阻止任何进一步的碰撞。我正在为我的砖块使用数组，因为我可以有很多，并且可以在被击中后将它们变成真或假

我的问题是我试图让球与所说的阵列砖碰撞，但即使通过尽可能多的谷歌搜索，我一生也无法弄清楚。 这是我的代码片段，我认为"应该"适用于碰撞

 for (int i = 0; 1 < brickLive.Length; i++)
                if ((y == brickLocation[i, 0]) && (x >= brickLocation[0, i]) && (x <= (brickLocation[0, i] + 60)))
                    yChange = -yChange;

据我了解，这段代码是针对 我检查球坐标是否在砖块位置的参数中的值。 如果是，则改变方向。使用当前代码，它运行良好，直到我开始游戏（我单击插入按钮，这使弹跳按钮起作用）

这是我的完整代码
