“I built an audio/visual event manager into
the Unreal engine so NPCs could detect
things like footsteps, gunshots, smashed
windows, objects hitting the ground, drawn
weapons, screams, distress, etc. -- and more
importantly, it could distingish between them.
I also wrote behaviors for the NPCs so they
could react appropriately to these events.”
