我已经研究过使用 EVEN-ODD Winding 规则来在一个区域中创建孔。事情在论坛上，我能想出的只是一个 Path2D.Double() 在其自身附加一个洞。我想在已经存在的 Path2D 中创建一个整体，就像 Area 类具有 Area.subtract(new Shape()); 做。生无可恋。我知道 Path2D 有能力提高我的游戏性能。
Path2D.Double d = new Path2D.Double(Path2D.WIND_EVEN_ODD);// this is a much larger circle which I will be using to subtract from the tile...
d.append(current_draw_area.createTransformedArea(mouse_point), false);//Note that this is an area without a winding rule...
Path2D.Double shape= new Path2D.Double();//this is actually a empty tile which is simply a rectangle, but will eventually have something in it to subtract from...
shape.append(d, false);
注意：输出应该是一个空的正方形，因为更大的圆圈完全覆盖了瓷砖，或者一个瓷砖的结果是圆圈相交和现有的瓷砖形状被移除，留下瓷砖的剩余部分......
