Question

我正在努力制作一个简单的乒乓球游戏，我遇到了两个问题，但似乎无法弄明白。

对于乒乓球比赛，我希望球员的球拍保持在Y的一半和更低的范围内，这意味着他可以将球拍移动到“球场”的一半之内。

我已经设法让挡板停在中间位置，但是击中中后它会出现。是否可以保持在Y轴的一半而不会消失？

另一个问题是玩家的划桨和区域似乎在上半部分，而不是下半部分。

您可能需要使用Mouse.SetPosition方法将光标推回到所需的矩形。

此外，我建议您实施自己的＆＃34;虚拟FPS风格鼠标＆＃34; （每个勾选你得到相对的鼠标坐标并将真正的鼠标光标推回到窗口的中心），高于一般鼠标类。如果光标有一些移动限制，它通常是一个不错的选择。
