aitesthull

This entity is not in the FGD by default.
It should not be put directly in a map.

aitesthull is a point entity available in all Source games. It is an "NPC" that verifies ai nodes are accessible by walking between node connections. This entity serves no use to mappers (other than assisting nodegraph building).

In code, it is represented by theCAI_TestHullclass, defined in theai_initutils.cppfile.
