4.7.1

• Bugfix: PhysicsCollisionEvent.getNormalWorldOnB() returns wrong value
• Bugfix: issue #20 (btAssert fails after HingeJoint.setAngularOnly(true))
• Added the needsCollision() method to the CollisionSpace class. This method can be overridden for dynamic collision filtering.
• Added the ContactListener interface for immediate handling of rigid-body contacts.
• Added the ManifoldPoints utility class to access the properties of a contact point without instantiating a PhysicsCollisionEvent.
• Added the PersistentManifolds utility class to access the properties of a contact manifold.
• Added 8 methods to the PhysicsSpace class:
  • addContactListener(ContactListener)
  • countManifolds()
  • listManifolds()
  • onContactEnded(PhysicsCollisionObject, PhysicsCollisionObject, long)
  • onContactProcessed(PhysicsCollisionObject, PhysicsCollisionObject, long)
  • onContactStarted(PhysicsCollisionObject, PhysicsCollisionObject, long)
  • removeContactListener(ContactListener)
  • update(float, int, boolean, boolean, boolean) to enable callbacks to specific ContactListener methods
• Deprecated the PhysicsCollisionEvent.setContactCalcArea3Points() method in favor of the corresponding ManifoldPoints method.
• Deleted placeholder files from class jars.
• Added the ConveyorDemo and JointElasticity apps to MinieExamples.
• Based on:
  • v7.4.1 of the Heart library,
  • v0.7.1 of the Wes library,
  • v0.9.10 of the Acorus library, and
  • v0.9.27 of the jme3-utilities-nifty library.
• Built using Gradle v7.4.1 .
• Updated the native libraries to v14.0.0 of Libbulletjme.
