I have been creating these two tutorial series for Unreal Engine 4. The first one is to get a working arrow in unreal, using instigators to pass information to the hit target and to fight whoever hit them (not just the player). This can be seen here!
The second playlist is to set up Enemy AI in Unreal. Both of these tutorials I approached from the roots, as if there was no previous knowledge to these subjects. You can watch this one here!
I hope these help everyone! Like, subscribe, and share this with the community, because I will be making a whole lot more!
