AI in Video Game NPC Behavior Quiz

Answers and explanations appear as you take the quiz.

1. What technique is most commonly used for NPC pathfinding in games?
   • The A* (A-star) search algorithm
   • Blockchain consensus
   • Convolutional neural networks
   • Quantum annealing
2. Most traditional NPC enemy logic is built from what?
   • Large language models
   • Handcrafted finite state machines and behavior trees
   • Genetic algorithms
   • Speech recognition
3. The game F.E.A.R. is famous for which AI technique?
   • Ray tracing
   • Procedural music
   • Goal-oriented action planning (GOAP)
   • Voice cloning
4. Why is game AI often deliberately made less than fully optimal?
   • To save electricity
   • Because computers cannot do better
   • To reduce file size
   • To make the game feel fair and beatable rather than frustrating
5. What is a key risk of using large language models to drive NPC dialogue?
   • Hallucinated lore and breaking the written narrative
   • NPCs becoming too quiet
   • Faster load times
   • Lower graphics quality
6. How do behavior trees help designers?
   • They render 3D graphics
   • They compose simple actions into reusable, controllable hierarchical logic
   • They compress textures
   • They handle online matchmaking
7. In A* pathfinding, what two values are combined to prioritize a search node?
   • The NPC's dialogue length and animation speed
   • The image resolution and audio sample rate
   • The cost so far and a heuristic estimate of remaining cost
   • The player's score and game difficulty setting
8. What does GOAP let an NPC do at runtime?
   • Render a more detailed character texture
   • Transcribe player speech without a dialogue model
   • Generate every game level from a random seed
   • Plan a sequence of available actions to reach a goal state
