I need an analog sensor Box2D, in bullet physics.
Tried to do so but can not find nothing

collisionWorld.getBroadphase().getOverlappingPairCache().setInternalGhostPairCallback(ghostCall);
btGhostObject ghostObj = new btGhostObject();
btCollisionShape shape = new btBoxShape(new Vector3(2, 2, 2));
ghostObj.setCollisionShape(shape);
Matrix4 trans = new Matrix4();
trans.idt();
trans.setTranslation(0,5,0);
ghostObj.setWorldTransform(trans);
ghostObj.userData = "LOL";
ghostObj.setCollisionFlags( btCollisionObject.CollisionFlags.CF_NO_CONTACT_RESPONSE | ghostObj.getCollisionFlags());
collisionWorld.addCollisionObject(ghostObj, (short)btBroadphaseProxy.CollisionFilterGroups.SensorTrigger,(short)(btBroadphaseProxy.CollisionFilterGroups.AllFilter & btBroadphaseProxy.CollisionFilterGroups.SensorTrigger)); |
