AIControllerが持ってるPawnActionsComponentってなんだ？って思ったけどDEPRECATEDなのか。AbilitySystemComponent使っとくのが良さそう

dtQueryFilterを継承して自作のQueryFilterクラスを作るしかなさそうだなぁ
getVirtualCost関数をオーバーライドするわけだけど
この中でQueryの要求(アクタがいるポリゴンはどこ？とか隣接ポリゴンはどれ？とかの要求)すると重くなるからダメ(この関数がそもそも沢山呼び出されてるせい)
経路探索する時だけ呼び出せばいいからAIcontrollerのMoveTo関数をオーバーライドして、FindPathする直前に必要な情報を更新すれば良さそう

For anyone using the StateTreeAI component, make sure its used on the AIController class, not the pawn class of the AI. Moreover, make sure the Start AILogic On Possess param = true if you want the StateTree to start automatically! #UnrealEngine #gamedev #gamedevelopment #ue5

Create an AIController script for enemies using a finite state machine (FSM) for aggressive, defensive, and sniper behaviors. Use NavMesh for pathfinding and set targets with `get_closest_enemy()`. Add toggles for state changes based on player distance and line-of-sight. #Godot #GameDev 💡

Lyra C++ upgrade: NPCs now respawn while their old corpses stay on the ground. Powered by OnDeathStarted + GameplayAbilities + a custom Spawner with clean AIController/LyraPlayerState teardown. Smooth, leak-free combat --> endless NPC AI wars. 🤖💀

AI adoption is exploding, but so are the risks: unmanaged access, spiralling costs, and zero visibility.

That’s why we launched AI Controller: a secure, self-hosted AI gateway for responsible adoption.
