The Urho3D C++ cross platform game engine just released version 1.32.  The following is the change log from this release:

 

 

  • Finalized Urho2D functionality, including 2D physics using Box2D, sprite animation and tile maps

  • Allow to prevent closing a modal window with ESC
  • Per-viewport control of whether debug geometry should render
  • Optional interception of resource requests
  • Readded optional slow & robust mode to AreaAllocator
  • Optionally disable RigidBody mass update to allow fast adding of several CollisionShape components to the same node
