Try to work with the helping elements before looking at the solution…

Helping elements

• Reminder: the project initialisation is done in two methods called in sequence: TraInitialParameters.buildInitScene(), then TraModel.initializeModel ()

• have a closer look in buildInitScene ()

• you will find a call to a loadInitStand () method

• this method (in TraModel) uses a file loader feature (TraInventoryLoader) in two passes:
  • first pass in the constructor, relies on the superclass to turn the text file into a list of so called Records, not what we are looking for here
  • second pass in load () to interpret the records and create the trees to be returned in the initial scene…

• …search in load(), something could be activated
