Things to be refactored

[psieg]

This is not a real ticket but rather a list of things to be done or considered as tickets

• Input pathways. Many classes call glfwGetKey() (e.g. keytrigger) where Input should probably be handled at a central point
• Camera / HUD access: many classes want to display things, should the be via world::instance()->player()? Ideally, everything important should be a configurable inputaction/keymapping (yes, even if nobody's going to change it)
• gamestates have accessors to their triggers so gameplay can set their targets. Is this the proper statemachine way? If yes, rethink
• global singleton soundmanager. does the job and everything, but when pausing the game I want the music to keep playing but the engines to pause etc - sounds should be part of the scene
• streamredirect - use again or remove
• Consider Multithreading approaches
  • de-singletoning the World is already planned. This should allow things like async loading
  • scripting, ai, maybe splitdetection and other things can travel to other threads
  • ideally, even the world simulation can be multithreaded for performance
• add whatever you stumble upon
