Would I need to modify anything other .cs to get this to work?

I found this weapons cycling code on the forums located here: www.torquepowered.com/community/resources/view/5907

If i wanted to use an m16 and a rocket launcher do I need to modify anything else such as inventory.cs and player.cs to have my character start the game with both weapons and be able switch back and forth between the two? Thanks in advance and any code to do so would be greatly appreciated! Thanks again.
