Loading Procedures

It is important, that everything in existance in orxonox is loadable e.g:

• general classes
  1. every loadable class should implement a function void loadParams(const TiXmlElement* root)
  2. all these classes should implement loading functions (see WorldEntity)
  3. write/extend the level-file

• world/campaign
  1. loading here must be handled better
  2. loading of environment has to be there, so everything that cannot move by itself belongs there

clean up the source, delete old unused stuff and make the source look nicer.
