04C9

IS_PLAYER_IN_FLYING_VEHICLE

---

Description

Checks if the player is in a flying vehicle

Syntax

04C9:   player [player handle] in_flying_vehicle

Parameter

[player handle]

The handle of the player

This conditional opcode returns true if the player is in a flying vehicle, either as a driver or a passenger. It behaves the same way as using both opcodes 04AA and 04AC together. By default the game will recognize the following list of vehicles as flying vehicles (for which the IS_HELI or IS_PLANE flag is set in the handling.cfg file):

• Hunter
• Maverick
• Police Maverick
• RC Baron
• RC Goblin
• RC Raider
• Sea Sparrow
• Skimmer
• Sparrow
• VCN Maverick

Legacy documentation describes this as applying to just planes.
