Nice series of tutorials on AI, you end up having a pretty intelligent, hostile bot. AI in UE4 is a topic that would be great to see that gets vastly covered, and this is a good start point, it will be interesting to see the path algorithm tutorial you are working on.
Additionally, if you want, you could enlarge the AI bran complexity in many ways: the enemy uses one weapon or another in function of distance; uses covers in the map to avoid player’s fire and has stealth tactics; jumps and pursuits the player character with efficieny in platforming-like maps… It could be great to see a tutorial or examples on something like that.
Anyhow, congrats for the good work!
