Ticket #74: Patch by or1andov, Integrate dialogue GUI and engine into game.

It should now be possible to engage in a conversation with NPC characters by
selecting talk from their context menu. fixes[s:trac, t:74]

Known Issues:

  • the GUI is terrible. instead of a dialog window, we could use a better looking background image and fixed position widgets
  • requires PyYAML to be installed sudo apt-get install python-yaml easy_install PyYAML
  • we have to create a simple state model for the PC can remember tasks
  • need to make NPC's be able to remember things - need a model in NPCs for this
  • no way currently to give or take items from npc's; again, more model work. this could be done by adding another callback similar to start_quest. may be necessary for npc's to have an inventory for this
  • The dialogue engine is not hooked up to specific NPC's... it currently always loads dialogue/sample.yaml - need to have the dialogue looked up from some XML attribute
  • dialogue is not broken off if the PC moves away from the NPC
  • npc image is hardcoded, it should use the image specified in the yaml file
  • Property svn:eol-style set to native
