Hi there, ok mechanim in unirpg is really on set up for basic NPC movement, unless you go and edit the scripts!!
UNIRPG is setup for Legacy animation, and once you get the hang of it you can pretty much the do anything with the animation set...
If you need any help with setting up the Lageacy anims then do shout, however there are several tutorials here on the forums for setting things up!!
Hope this helps!
