如何使透明面板的图片框出现？
How make pictureboxes of a transparent Panel to appear?
我正在制作 windows 形式的 2D 游戏，但我遇到了问题...
所以，我有一个面板，其中所有 "Ground" Tiles (PictureBox[]) 都是...但是我需要在 "Ground Tiles" 上面有另一个面板，而不是仅仅设置 PictureBox.Image ，所以它看起来像是玩家在某物后面......但是那个面板需要是透明的，并且它的图片框需要出现才能产生效果，但它没有......我放置瓷砖（PictureBox）的原因在 Panel 内部，这是因为我想制造一种错觉，即相机聚焦在玩家身上（意味着玩家并没有真正移动，是 Panels 在移动）。
有人能帮帮我吗？我知道它看起来很复杂...抱歉...

这就像在另一个面板上叠加一个透明面板...
我试图将第二个面板设置为透明，但它的图像没有出现。

我想做的基本上是3层面板...
PropTextures（比如玩家是否在某物后面）
Player Texture / PropTextures（与物体碰撞）
地面纹理（玩家可以或不能行走的地方）
PictureBox 控件未提供您尝试使用的透明度。如果您继续当前的方法，我认为您不会有太多运气。
这里有一个替代方法的提示。如果您在使用 PictureBox 控件等时遇到困难，那么您可以自己进行渲染。创建一个 DoubleBuffered 的 UserControl，并在 Paint 事件中，为每个精灵调用 Graphics.DrawImage 以将每个图像渲染到正确的位置。这种技术的好处在于，以这种方式绘制精灵时，您将获得正确的 alpha-correct 合成。请务必对它们进行排序，以便从后向前绘制它们，"paint over" 背景精灵使用前景精灵。
