source: orxonox.OLD/branches/proxy/src/world_entities/skybox.cc @ 9646

Last change on this file since 9646 was 9625, checked in by patrick, 18 years ago

yet another weekend commit, quite much work done:

  • introduced a new PERMISSION layer: PERMISSION_SERVER: the nearest server hast authority
  • tightening up permissions: brand new implementation to prevent sending unused variables in the network (less smog in the net:D_
  • removed some compiler warnings from some central modules
  • networkmonitor interface changed to work with networknodes mainly
  • better debug output for the network monitor
  • networnode inteface standardisation
  • force reconnection commands integration
