In this episode we start work on what will be a cornerstone of our AI system in the game we're making: EQS, the Environment Query System. In playing hide and go seek, whenever the AI loses line of sight, it needs an intelligent way to 'guess' where its target might be. This is what we set up EQS to be able to do- to 'speculate on' (I.E., score) possible locations that our player character may be hiding and search accordingly. We also cover how to debug EQS with the standard AI debugging tools in Unreal Engine. Lastly, we cover how to solve the issue with AI characters occasionally getting 'stuck' in their movement.

Although this is just an intro to EQS, we are going to be using EQS quite a bit for our AI over the course of this series.
