start a new toribash game, type /ls worldbuilder.lua to load the worldbuilder.lua script then press h for the help prompt on what to do further, it depends if you're on a keyboard or not so if you aren't just use the keypad on the right of your keyboard and press 5 to create a new object, if you're on a keyboard press k and then press "~" to create a new object (I think).. and then just place your objects carefully.. it helps to write down the coordinates if it's your first time building in a 3d environment just so you get an understanding of the XYZ planes. Then, press enter.. sometimes you have to press it twice, save your file as a name you'll remember. Then when your file is saved with objects, go to the directory where you installed toribash (default C : / Games / Toribash/) and find the scripts folder (data>scripts).. find the name you saved the file as, copy it (in case you want a backup, otherwise just cut it) and paste it into your mod folder (data>mod) and rename it to "yourmodname.TBM".. to do this you'll have to open the file as a word document and re-save it as (save as) "all documents" and that's when you can add the ".tbm" extension.. Then, to create static objects (objects that will never move, like in this mod) you have to give them a flags value of 8, so re-open your newly created mod file, find where it has flag values and change them all to 8. And voila.
