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

fan effect code done

i was thinking of making something with Fan
so i did 1 module as how can one make object to sustain in AIR. :)
well the concept behind this is just make one Base object and one target Object
then find this distance between them and applyforce in y direction

like this
var forcex=Math.round(body.GetPosition().x-wallB.GetPosition().x);
var forcey=Math.round(body.GetPosition().y-wallB.GetPosition().y);


trace(forcex)
if (Math.abs(forcex)>=1&&Math.abs(forcey)>=1) {
body.ApplyForce( new b2Vec2(10/forcex, 50/forcey), body.GetWorldCenter());
}
