Out of Sight, Out of Mind: Improving Visualization of AI Info

Bill Merrill  |  AI Lead, Turtle Rock Studios
Mika Vehkala  |  Principal Game Tech Programmer, Guerrilla Games

Location: Room 3007, West Hall

Format: Session
Track: AI Summit
Vault Recording: Video

When AI was simple, debugging consisted of confirming that the character was simply doing the one thing you expected. Over time, debugging moved away from "what" and became more about "why?" or "why not?" The collision of information about the agents, the environment, the player and the game state creates an enormous amount of data that can affect the decisions that the characters make. In this session, three developers will share methods that their studios employed to expose that information in manageable, understandable ways to programmers and designers alike. Bill Merrill of Turtle Rock Studios will explain a simple yet powerful timeline-like view they used in the upcoming Evolve. Charles Gast will show details of their HTTP-based Game State Inspector, allowing powerful information widgets for The Sims 4. Mika Vehkala will demonstrate features of ReView as used for debugging the multi-player bots in Killzone: Shadow Fall.


Attendees will see a variety of existing methods for visualizing information for developing, tuning and debugging AI, and plenty of ideas for developing their own visualization tools.
