重叠的身体

Question

我有两个DYNAMIC主体body1和body2都定义为：

final BodyDef ballBodyDef = new BodyDef();
ballBodyDef.type = BodyType.DYNAMIC;

final PolygonShape ballShape = new PolygonShape();
ballShape.setAsBox(10f, 10f);

Body ballBody = world.createBody(ballBodyDef);
final Fixture ballFixt = ballBody.createFixture(ballShape, 0.2f);
ballFixt.setRestitution(0.7f);
ballFixt.setFriction(0.5f);
ballFixt.getFilterData().groupIndex = -1;

他们不会发生碰撞。

是否有一种简单的方法可以检查它们是否重叠？

public boolean overlapping(Body body1, Body body2) {
    //Check overlapping ?
}
