why when ball1 hit another ball2
ball2 move by the force but ball1 dont get return force (elastic)

p.s
i defined the elasticy force to 50...
and still nothing

should i use the old way like


var min_dist_between_balls = 10;
var dist_between_balls;

dist_between_balls = ball1.x - ball2.x;
if (dist_between_balls <= min_dist_between_bals)
{
phent_addcentralforce(ball1, lunchpower);
}

this will work??
