我正在制作一个Windows游戏的2D游戏，我有一个问题...... 所以，我有一个Panel，其中所有的“地面”瓷砖（PictureBox []）都是...但不仅仅是设置PictureBox.Image，我需要在“Ground Tiles”上方有另一个Panel，所以它可以看起来就像玩家背后的东西......但是那个面板需要透明，它的图片框需要看起来才能产生效果，但它没有...我把Tiles（PictureBox）放在Panel里面的原因，它是因为我想让镜头聚焦在玩家身上的幻觉（意味着玩家并没有真正移动，其移动的是面板）。
有人能帮帮我吗？我知道它看起来很复杂......抱歉......

就像在另一个面板上覆盖透明面板一样...... 我试图让第二个面板透明但它的图像没有出现。
This may help you to understand
我想要做的基本上是3层面板...
PropTextures（就像玩家背后的东西一样）
播放器纹理/ PropTextures（与对象碰撞）
地面纹理（玩家可以走或不走的地方）
答案 0 :(得分：0)
PictureBox控件不提供透明度，即您尝试使用它的方式。如果你继续使用目前的方法，我认为你不会有太多运气。
所以这里是替代方法的提示。如果您在使用PictureBox控件等操作时遇到困难，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sprite调用Graphics.DrawImage将每个图像渲染到正确的位置。这种技术的好处在于，当以这种方式绘制精灵时，您将获得正确的alpha校正合成。只要务必对它们进行分类，以便从后到前画出它们，然后画上＆＃34;使用前景精灵的背景精灵。
