简短版本：
如何从物理正文编辑器获取基本com.badlogic.math.gdx.Polygon？
长版本：
我已经为 LibGDX 实现了加载器，但加载器通过其内部RigidBody类使用它自己的内部PolygonModel类。 最终，我可以从每个单独的多边形中获取每个顶点，并从那里构建我自己的多边形。但这似乎不是很"微不足道"。我想到的东西是这样的：
List<Polygon> myPolygons = new ArrayList<Polygon>();
Map<String, BodyEditorLoader.RigidBodyModel> bodyMap = loader.getInternalModel().rigidBodies;
for (BodyEditorLoader.RigidBodyModel m : bodyMap.values())
{
for (BodyEditorLoader.PolygonModel pm : m.polygons)
{
float[] vertArray = new float[pm.vertices.size() * 2];
int count = 0;
for (Vector2 v2 : pm.vertices)
{
vertArray[count] = v2.x;
vertArray[count + 1] = v2.y;
count += 2;
}
myPolygons.add(new Polygon(vertArray));
}
}
这相当麻烦，我有这个完整的加载器，只是为了剥离它构建的所有内容，直到索引并从中构建我自己的多边形。但是，编辑器确实为我提供了一个 json，但不幸的是它是一行，因此 json 的好处被浪费了。如果我可以手动修复布局并破译需要解析的内容，但我想知道我是否没有在这里重新发明轮子。
除此之外，可能只有一个非常简单的解决方案来获取我的多边形。
我需要它做什么？好吧，我正在为我的精灵寻找一些精确的碰撞检测。矩形和圆形将无法完成这项工作。多边形非常适合此，它们有一个用于廉价检测的矩形Intersector并且可以处理两个多边形的碰撞。我能想到以某种有效的方式创建这些多边形的唯一方法是使用我链接到的编辑器。
如果有人有更好的建议，我会全力以赴。
这就是我当前的 Json 输出的样子。它对我来说有冗余节点，但解密是一种痛苦，只有一行没有空格和行尾。

我想
部分回答我自己的问题。由于 Json 的输出不可读，我转到 jsoneditoronline.org/并粘贴了 Json 的单行。通过将代码复制到树编辑器并返回到代码编辑器，我现在有了 JSON 的可读版本。
它仍然有冗余节点，这个工具只是给了我原点，索引/顶点将是完美的。但是，通过此解决方法，我可以继续将这个出色的工具用于我的资产。
