In my code there are two balls with certain velocity both from different direction collide with eachother... After Collision they are supposed to bounce back with certain velocity...But in my code they just stuck together the moment the collide eachother.

I tried to set restitution value 15 for both bodies, but the bodies vanish after collision...
Any help would be highly appreciated.

Thanks in advance>>

protected void init(World world) {

world.setGravity(0,0); //

Body BallA= new Body("Cart", new Circle(15), 100);

Body BallB= new Body("Cart", new Circle(15), 100);


BallA.setPosition(150, 375);
BallB.setPosition(300, 375);

BallA.adjustVelocity(new Vector2f(20f, 0f));
BallB.adjustVelocity(new Vector2f(-20f, 0f));
         
//          ball1.getBody().setRestitution(15);
//          ball2.getBody().setRestitution(15);

         
         
world.add(ball1);
world.add(ball2);

Have you tried playing with other restitution values?  such as between 0.3f and 0.7f ?

Although I am not as familiar with Phys2D as I usually use box2d.

Also, do you have a proper update function and other areas of code(not shown)  feel correct?

I was giving too much restitution value of 15...
when i tried setting restitution value between 0.3 to 0.9...its working fine...
Thanks again..
