Environment Query System Node Reference

Environment Query System Node Reference page.

An Environment Query is made up of many different pieces. You must call an Environment Query from a Behavior Tree, and then the actual Environment Query will use its Generator, reference its Contexts, and use its Tests to give the Behavior Tree the highest weighted result.

Node Type



Produces the locations or Actors, referred to as Items, that will be tested and weighted.
