Lectures

Sensing is the most expensive part of the sense-think-act cycle. In this lecture we show how to optimize this part of the process, so that we can increase the complexity of our NPC behavior.    Details ›

When people think about game AI, character behavior is the thing that they usually think of first. How do we control NPCs to move and act without any input?    Details ›

We start our sequence of AI lectures talking about pathfinding. This is the process of using AI algorithms to move your game characters about the terrain.    Details ›

Box2d is the primary physics engine for 2d games (even though this is the result of a historical accident). In this lecture we discuss its features and show how to use it effectively.    Details ›

Game physics can get really complex, so fortunately we have physics engines to help us with all the hard parts. But before we learn how to use a physics engine, we first need to understand the big picture.    Details ›
