This is an extension I made that gives developers more control over how survivor bots behave when it comes to pathfinding. The video demonstrates the survivor bot avoiding nav areas that have the "AVOID" attribute, which is the default behavior of the extension itself. There's also an API so developers can easily create plugins to modify pathfinding behavior themselves.
