java - 获取多边形体的顶点列表

Question

如何在 libgdx 中获取特定多边形主体的顶点列表？

像这样:

public Array<Vector2> getVerts(Body body){
    Array<Vector2>verts = null;

    // can't find how to look them up properly anywhere

    return verts;
}

谢谢!

我没有使用过 LibGDX，但我使用过 Box2D 并查看了 API，我建议:

//Assuming only 1 fixture per body and a polygon shape


Array<Vector2>verts = new Array<Vector2>();
Fixture f = body.getFixtureList().get(0);
PolygonShape s = f.shape;
for (int i = 0; i < s.getVertexCount(); i++)
{
    verts.add(s.getVertex(i, /*I couldn't figure out what this param is supposed to be*/));
}

_{这是在没有 IDE 的情况下输入的，注意明显的错误!我也好久没搞Java了。}
