AI Summit Highlights
Here are some moments from Monday that stand out. (Not all sessions have been included here, more will follow.)
- Daniel Brewer showed how simple coordination techniques can help provide enemy barks and responses that are unique and diverse during combat. He also showed how The Darkness 2 uses reciprocal velocity obstacles to resolve low-level collision issues, among many other interesting combat technique implementations.
- Michael Dawe showed some entertaining examples of how the work of AI programmers can often be abused by designers, in particular boss-specific Lua script hacks that are then later expected to work generally for all characters. Or taking 22ms to spawn and unspawn chicken on a regular basis.
- Kevin Dill showed how you can build modular decisions for your AI by creating considerations that you can plug together easily, each based on a combination of rank and weight. Both these floating point numbers are used in a utility-based fashion to pick the most sensible behavior applicable at any time.
- Guild Wars 2 faced some very interesting challenges to provide AI on such a large scale, but they were mostly system and architectural rather than AI-related. Mike Lewis described a pragmatic solution based on assigning specific cores to simulate games/worlds as a single thread of game logic, with underlying infrastructure helping make everything simple and thread safe.
- In his rant, Brian Schwab lamented the situation why designers seemed to fear and mis-understand AI programmers and that we should all work together — especially with the coming invasion of the cyborg robots.
- Neil Kirby explained stories from the testing department trenches, and how developers can make the most of them to produce robust and high-quality AI code.

Thanks to everyone who attended and it's been a pleasure to hear such great feedback. We'll be making the an extended edition / directors cut available at some stage, so stay tuned for details.
