I've almost finished to sort and reorganise all definitions that JohnW extracted with his script. Ok, there's not the materials, tilesets and recipes definitions, no models or *.dds either ( for models, you have the 1.3.3 assets extractor for blender ), but you can acces to :
Armours, Ceilings, Cinematics, Containers, Doors, Floors, Items, Lights, Logics, Monsters, Obstacles, PSystems, Pillars, Props, Scriptings, Sounds, Spells, Stairs, TP, Visual effects, Walls and Weapons definitions ( without onXXX functions ). Not so bad
I'm actually finishing to sort theses definitions for who wants study them or just inspire from. I'll publish them this weekend.
