Hi TRX1
As far as an entities .fpe goes, there are not too many video tutorials for that propose. It really is simple to make one.
Just open any entities .fpe and study it and you'll get how it's setup. Also if you have Entity Workshop 2 it will make the .fpe's
for you. Here's a link to it...

It is also included in the tools folder with Black Ice Mod now.
As for the .fpi scripting language, once you get the hang of it it's very simple.
Grab a copy of FPI EditPad, The Complete Syntax List, and look/study Blackfox's General Script Information on the scripts forum
main page. Here's a link to one that got me started on the right track by Plystire....
