Is This Quest For You?

Perfect for you if:

  • You have combat working and want something to fight
  • You want clean, extendable AI instead of if/else spaghetti
  • You're building a top-down action RPG
  • You want to truly understand the state-machine pattern

Not for you if:

  • You haven't built movement and combat yet
  • You want 3D enemy AI (see the 3D Soulslike campaign)
  • You want advanced squad or utility AI
  • You'd rather not set up navigation regions
