• CBaseHelicopter
• CAI_BaseNPC (NPCs)
• CBaseCombatCharacter
• CBaseFlex
• CBaseAnimatingOverlay
• CBaseAnimating (models)
• CBaseEntity (all ents)

CBaseHelicopter is a code class shared by large flying NPCs. Unlike most NPCs, these ones are told where to go by path_tracks.

Note: These NPCs are not designed to be within touching distance of a player while alive. They tend to make the player lose momentum when touching.

Flags

• 32: No Rotorwash - Makes the NPC not emit rotor wash (effect of air being pushed downward).

• 64: Await Input - NPC waits for the Activate input to begin flying.
