Quite a few people asked for a PDF of my slides from my lecture at the GDC in Lyon, but I promised to do better and release a video with the animations an the whole audio. Here is the first part of the talk; it’s exactly 22:37 minutes long.

In the video, I go over the motivation for behavior trees, in particular how they relate to other techniques using hierarchical logic and what problems they address. I also give a quick introduction of the concepts behind behavior trees using a simple guard dog example that you should be familiar with if you’ve been following the tutorial series here on AiGameDev.com.

It took much longer than expected to prepare, but at least I’m a little more comfortable with video editing tools now! The second part will be posted this Sunday, and is reading for being edited… Be sure to subscribe to be notified when it’s released.
