I am trying to make a spider a pet.  So far, it is tameable, but once it is tamed, it sits there.  It seems to be ignoring its goals even though I get the tamed advancement and his texture switches.  He moves and if he's attacked, he defends himself, but he won't follow.  I'm completely new to this, maybe a few weeks in, but I know C# and some Java.  I used the TameableEntity class extending IAngerable mimicking the WolfEntity class without all the collar and swim code.  Any suggestions would help.  I hope it's something simple I'm not doing.  I've added some unnecessary code trying to figure out what I'm missing from the WolfEntity class but would appreciate any help or ideas.

You should try reordering the goal priorities, my entity wouldn't attack until I increased the melee attack goal priority.
