I added actual arrows, with trail, a bow with an animated string and a quiver as well as sounds for loading, string tension, shooting and arrow-woosh…

So the skeleton follows you and it has a range after which he starts shooting arrows while walking, if he gets closer he stops walking and just shoots arrow and if you move away he will continue pursuit.

I had him running like his sword wielding buddies, but that was a bit too much and would be lead to less variety. So zombies are the slowest, archers are slightly faster, but they have a range and skeleton warriors are really fast, but have a short range (melee).

I will add some randomness to his targeting as well and call him done for now (which means awaiting a modeling and texturing pass, basically polish)
