我将为随机块添加一些能力，你知道当你击中随机块时它会下降。就像你得到 2 个球或更大的球拍或更慢的球速。

我在编写 for 循环和 if 语句方面需要帮助，这可以为我的块级别添加一些功能。就像 1 级的 1 个随机能力等等。因此，当您击中 1 个 20 块的随机块时，这就是我的能力。它会像原来的突围游戏一样落到桨上。

我正在考虑一个开关，如果一个具有能力的随机块被击中并使用该开关并将其随机化。

您可能希望将块数据封装到一个类中，其中包含块的颜色、位置和电源。
您可以在内部有一个称为“AddPowerup()”或其他方法的方法，该方法将用于向块添加随机（或特定）电源。您可能需要一个吸气剂来进行通电。

现在在您的游戏中，您可以将关卡的所有块保存在一个列表、一个二维数组或任何适合您的集合中。然后，为了对关卡中的随机块应用加电，您可以执行类似这样的操作（主要是伪代码，所以未经测试）：

List<Block> blockList = CreateBlockLevel(1);
int randomIndex = new Random().Next(blockList.Length-1);
blockList[randomIndex].AddPowerup();

如果你想对多个方块应用一个通电，你可以把它放在一个 for 循环中，但是你可能想检查这个方块是否已经通电了。
