android - Bouncing ball in libgdx using bullet3d physics -

i trying create programme of bouncing balls uisng libgdx in 3d.i finish beginner started getting hands on libgdx. able observe collision between bat , ball unable bounced back

here finish code public class main implements applicationlistener { final static short ground_flag = 1 << 8; final static short object_flag = 1 << 9; final static short all_flag = -1; class mycontactlistener extends contactlistener { @override public boolean oncontactadded(int uservalue0, int partid0, int index0, int uservalue1, int partid1, int index1) { //instances.get(uservalue0).moving = false;

here updated code right able bounce ground not objective objective bounce ball when hits code applied moving of ground unable appied ball. please help.

here code.finally ball bounce
