Entity Description

A nodegraph and hint node for Flying NPCs that includes some context information for NPCs that are interested in it. The hint might indicate a window that could be looked into, or an item of interest that could be commented on. Many hint types are NPC-specific, so it's helpful to use naming conventions like 'Crow: Fly to point' in the hint choices list. The angles of a hint node indicate what direction the NPC should face to perform the hint behavior.

Identical to info_node_hint but used for airborne NPCs.
