Question

我有一个游戏，允许用户创建自己的图片。他们可以从我创建的菜单中选择不同的元素。当他们单击一个元素时，会创建一个实例，他们可以拖动到上面的工作区域。他们正在创建的图片呈圆形，因此，如果用户拖动圆圈边缘附近的元素，它应该被切断。 *（想象一个矩形图像，中间有一个透明圆圈，你可以看到所有元素通过）

目前，我可以将一个元素拖到工作区域，它只会显示在圆圈内（如果它在圆圈外面则会被剪切掉），但是一旦拖动它，我就无法点击并拖动它再次，因为它是在图像下。

如何让矩形图像显示在所有元素的顶部，同时仍允许用户点击并拖动已放置的元素？

（我制作了一个图表，以便更容易理解，但我没有足够的代表点发布它）
