ADD body to an existing one

var wallSd2l:b2PolygonDef = new b2PolygonDef();
var wallBd2l:b2BodyDef = new b2BodyDef();

var boxDef11:b2PolygonDef = new b2PolygonDef()
var wallB2l:b2Body;
wallBd2l.position.Set(12,5);//8.8
//wallSd2k.restitution=1

wallSd2l.SetAsBox(.1, 2);
//wallBd2l.angle=-.45
wallB2l = m_world.CreateBody(wallBd2l);
wallB2l.CreateShape(wallSd2l);
wallB2l.SetMassFromShapes();


////////

boxDef11.SetAsOrientedBox(2, 0.1, new b2Vec2(0, 0), 0);//w h x y angle
wallB2l.CreateShape(boxDef11);

Fly Up AND Left

var forcex=Math.round(body.GetPosition().x-bodya.GetPosition().x);
var forcey=Math.round(body.GetPosition().y-bodya.GetPosition().y);

var nullX=Math.sqrt((forcex)*(forcex) + (forcey)*(forcey))

//if (Math.abs(forcey)==0)///fly horizontal
if (Math.abs(forcex)==0)///fly up
//if(body.GetPosition().x>5 && body.GetPosition().x<7 && body.GetPosition().y<9)

{
trace("rt")
body.ApplyForce( new b2Vec2(-3, 0), body.GetWorldCenter());
}

Set Mass At run Time

To change the mass at run time just make desity=0 at the time of defining body
and in At run time Change its Mass


Update()
{
var massData = new b2MassData();
massData.mass = 1;

massData.center = new b2Vec2(-1,1);
massData.I=2
wallBd.SetMass(massData);//wallBd is a body
wallBd.WakeUp()
}

//////////////
bodyDef1.isSleeping = true; is used to make body active whenever its hit by anyobject
