There's a call in the story code which shows the mining animation:
CharacterPlayAnimation( _Char, "use_mine", "mine_anim_end" );
But I could not find any call to equip an item, so I have no idea how the pickaxe is 'equipped'.
I know absolutely nothing about animations or graphical stuff, so someone else would have to help here.
And, adding NPC's is not one of my strengths either, I could not even make the one single NPC I added in a mod say anything, although I thought I had added everything necessary. So I'm no help here either.
Most if not all tutorials here on the forum were made for the Classic version but pretty much everything still applies to the Enhanced Edition, with only some minor differences.
