Question

对于我的一生，我无法弄清楚自己在做错什么。我设法使一个球员，并使其射击。我还设法使图片框中的球以随机的位置/速度产生。

我无法获得任何Collision的帮助。我试图将所有球都留在图片框内，然后反弹并相互反弹，然后在射击时销毁它们。

我一直在尝试使用Ball.Bounds.IntersectsWith(pictureBox2.Bounds)，但似乎Ball.bounds是错误的。

我有一个模糊的想法，为什么它是错误的但不是确定的。我在box.cs中的财产范围错误，或者我不知道如何将其与我所有的球的位置相关。

由于我在这个问题上已经停留了一段时间，所以朝正确的方向稍加推动将不胜感激。
