android - 通过box2d在android andengine中创建圆圈？

Question

我可以创建矩形来创建墙，例如：

    final Rectangle wall = new Rectangle(CAMERA_WIDTH-2, 0, 2, CAMERA_HEIGHT -2);
    PhysicsFactory.createBoxBody(this.physicsWorld, wall, BodyType.StaticBody, FIXTURE_DEF);
    scene.attachChild(wall);

但我想创建圈子？例如 ball.it 应该是上面的 box2d 的主体。

Answer 1

其实很简单：

Body circleBody = PhysicsFactory.createCircleBody(pWorld, pSprite, BodyType.StaticBody, FixtureDef);
