Bah. Mods are for losers.
Finally tamed my first wolf... and unfortunately, Flake doesn't seem very intelligent. I ordered him through some basic tasks, and here's how he came out:
Moving through a 1x1 hole in the wall: FAILED
Jumping up a 1x2 block staircase: FAILED
Attacking mobs in the most efficient way possible: So-so.
Following me: FAILED
I think Flake will just have to be window dressing for a while until I make my house more dog-friendly.
