Unity AI Behavior Systems

AI makes games feel alive.

Better AI improves gameplay depth.

Behavior Types

Common AI systems include:

  • Finite State Machines (FSM)
  • Behavior Trees
  • Utility AI

Each has different complexity.

Finite State Machine Example

States:

  • Idle
  • Patrol
  • Attack
  • Retreat

NPC switches between states based on conditions.

Performance Considerations

AI systems should be optimized.

Avoid running complex logic every frame.

Final Thoughts

Good AI enhances player experience.

Design behaviors thoughtfully.
