yes, text edit will work just fine, just bouble click on the .cs folder in your addons folder (in applications -> blockland) and click on like say "gun.cs" and copy it. open the copied version, then you can mess with the textures and values. not you will have to chnage the datablocks, if you dont it wnt wrk properly, you will have to do that for every new weapon/vehicle you create, and always rename the .cs file. These are datablocks (in red):

and it goes on, you get the idea. look around in you shapes, sound, and other folders in your addon folder. you can add sounds to your sound folder, and change it is your .cs files. that is a baisic overview of how to make .cs files and mods. if you ned help, ther are alot of experianced users in the coding help section of the forums.
you dont code from scratch unless you know torque script, you can get the torque engine here:
http://www.garagegames.com/
3d modeling: there are lots of ways ad programs that you can model things, what you should start with is google sketchup, it is avery easy to use program, and ony of the only good and easy ones for your mac. it can be found here:
http://sketchup.google.com/well, that wraps things up, and don't forget to tell people that you have a Mac, you failed to state that, but i have mac and windows so i know what you are talking aboutÂ
. good luck!
