Horses shouldn't get hit from you when they are following you, unless it is lag causing this, then make it a bit more secure
Umm, something something...
Change the angle nodes of the horse to include true cardinal directions. I think down, right, and either left or up are a little off (I'd check but my horse doens't like me right now...) I'd suggest creating an array to hold the vector components instead of having them calculate with sin, cos on the spot.
And, that's all I have right now... Good Day
