Hahaha...that's great, Jedi Knight was my first real exposure to programming. Great times trying to make more and more sophisticated modifications of the game files...either legitly (custom levels, mods) and to use in unsuspecting multiplayer games on MSN Gaming Zone. I remember some members of the modding community ending up becoming serious level designers or game developers.

You could actually make more complicated hacks by making deeper modifications to the weapon/force power scripts. The game had a simple checksum on the client-side script files where it did a rudimentary count on the number of statements (method argument: one statement, pair of parentheses: one statement), and if you had a count identical to the server file, the rest of the contents of your script didn't matter. So you could basically do a lot of stuff as long as you were careful to keep the script file statement count intact: Change the properties of the levels or surfaces, give yourself all sorts of superpowers, freeze or insta-kill opponents, teleport yourself or others, etc etc etc. The scripting language was somewhat C-like and carried over pretty easily to more traditional programming.
