Some newb ?'s How to add enemies & how do I install text
Welcome to the forums! 
1.) There's a great explanation in the 'Making 3D Games with RF' book. It's free and can be downloaded here.
There's a lot of information about 'pawns', which are scripted characters, either friends or foes.
Basically it goes like this:
Create the model for the enemy in you 3D modeling program.
Import it to RF using the ActorStudio program.
Define a new 'pawn type' in the pawn.ini file using your actor - more info can be found in the RF Manual (located in \docs folder).
Write the enemy script... this is probably the most complicated part, but again, there's lots of info in the manual and in the book I mentioned before.
Some sample scripts come with the RF installation (something like GenericMelee.s, GenericMissile.s etc..)
In the level editor, add an entity called 'Pawn' and fill in the fields. More info in the RF manual, in the section called 'Pawn'.
If you're completely new to RF, this may be hard to understand. But just ask us and I'm sure that at least someone will be happy to help.
I don't have time right now so I can't write a detailed tutorial.
2.) In the \tools folder there's a tool called rfPack.exe. That's the texture packing tool. Open an existing texture file (.txl) or create a new one with it. Then just drag and drop the textures to the list and save the file. To use the textures in the game, you'll need to open up 'level options' in the level editor and change the 'texture library' to whatever your .txl file is called. You'll need to add the path too.
3.) Weapons are defined in the install\weapon.ini file. There's a section called 'weapon and projectile definition' in the RF manual. It comes handy here. There's also some good info in the RF book.
I hope this helps... If you have any questions at all, feel free to post them.
