android - 关节体不跟随真实的 body

Question

我用这两个 body 连接起来。 Player body 和他的 foot body。但是 footBody 不跟随 player body。？

  final FixtureDef fixtureDef = PhysicsFactory.createFixtureDef(0, 0, 0.1f);
    this.body = PhysicsFactory.createBoxBody(this.mPhysicsWorld, this, BodyType.DynamicBody, fixtureDef);
    this.body.setUserData("player");
    this.body.setFixedRotation(true);
    this.mPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(this, this.body, true, true));
    this.setCurrentTileIndex(8); //Başlangıç resmi

    this.foot = new Rectangle(this.getX()-20, this.getY(), 10, 50);

    final FixtureDef footFixtureDef = PhysicsFactory.createFixtureDef(0, 0, 0, true);
    footFixtureDef.isSensor = true;
    this.footBody=PhysicsFactory.createBoxBody(this.mPhysicsWorld, this.foot, BodyType.DynamicBody, footFixtureDef);
    this.footBody.setUserData("foot");
    this.foot.setColor(0.9f, 0.3f, 0.6f);

    this.mPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(this.foot, this.footBody, true, true));

     final WeldJointDef joint = new WeldJointDef();
     joint.initialize(this.body, this.footBody, this.body.getWorldCenter());
     this.mPhysicsWorld.createJoint(joint);
