Is this the tutorial http://www.leadwerks.com/werkspace/page/tutorials_legacy/_/making-a-third-person-camera-r16, you're refering to?
There's a Lua section, which should be working for the indie edition, given that the scripting language hasn't change in that regard.
You might be better off asking a specific question about the code than requesting a whole tutorial; you'll get a quicker response.
I know that it's not much of a help - sorry.
