JEDI-KNIGHT structure

We are going to see how Jedi-Knight is built and how the game works, without going to details which would be too long and difficult.

The game , is first an engine, the executable: JK.EXE which calculate movements, interactions with player and world, define which animation to play and when, play sounds, calculate dynamic lightings if there are some. All this using scripts (COGS) that are compiled while the level loads. Those scripts are for the base functions automaticaly started by the engine where they are stored and for all others compiled and loaded at the game start .

The second base element is the .GOB file or container, that contains all the datas needed by the level. It's with such a file that we can publish a level and distibute it. It's very easy to install a level : you just have to put the .gob file in the EPISODE folder of Jedi-Knight. So when the game start you can choose the custom game in NEW GAME in the start menu.





The container can store many kind of datas :







The file which define and give the level structure : EPISODE.JK



The geometry, objects types and positions : .JKL file



The scripts for this level : .COG files



Les textures additionnelles : les fichiers .MAT



The custom objects : .3DO files



Animations corresponding to the objects : .KEY files



Les descriptions d'animations reliant les .3DO aux .KEY : les fichiers .PUP
