Start of a Tower Defence game in Unreal Engine 4 - Part 1

Update: http://youtu.be/ESWQcsl16wA I've just been trying to teach myself unreal engine 4. This video shows a basic map with a AI Character running to two target points in bottom and top left. Its using a NavMesh for the AI to determine its pathing. The turret is targeting using getAllActorsofClass() then simply choosing the actor type of AICharacter. I'll change this to also check the distance and only fire upon units within range. Lots more to do, but this is a start...
