DoN's 3D-Pathfinding / Flying-AI system (with full source!)

[Ryan_Darcey]

I’m having trouble getting my flying pawn to chase the player. It flies between waypoints fine, but whenever the player steps into its vision cone it loses confidence. It will fly to the player’s location, but then it stalls and waits. If the player reactivates its senses by making a noise or stepping out and into its vision cone again, then it repeats.

What’s your BTD_CheckDistance doing? I was running into problems using a standard UE4 distance check (can’t remember which one and don’t have access to my project right now) cause there was a (bad) assumption made in the function that in order for the distance check to return true, there was an additional check to ensure there was some minimal vertical offset between the characters that had nothing to do with the point-to-point distance.
