BMBaseHelicopter

MoveTopSpeed The helicopter will immediately move at top speed toward its current goal, or in its current orientation if it's on top of its goal. MoveSpecifiedSpeed <float> The helicopter will immediately move at the specified speed (you provide this as parameter override in units per second) towards its current goal. ChangePathCorner <targetname> Tell the helicopter to move to a path corner on a new path. SelfDestruct Self Destruct. Activate Activate. Use to wake up a helicopter that spawned with the 'Await Input' spawnflag on. SetTrack <targetname> Set a track for the helicopter to adhere to. The helicopter will do nothing if it's on the same path, and will move to the closest point on the specified track if it's on a different path. FlyToSpecificTrackViaPath <targetname> The helicopter will first fly to the closest point on the path if it's on a different path. Then it'll fly along the path to the specified track point. FlyToPathTrack <targetname> The helicopter will fly to the given path_track. StartPatrol Start patrolling back and forth along the current track. StopPatrol Stop patrolling back and forth along the track. This will cause the helicopter to come to rest at the track which he's currently flying toward.

ChooseNearestPathPoint When tracking an enemy, choose the point on the path nearest from the enemy. StartBreakableMovement The helicopter is now allowed to disobey direct commands to go to particular points if it senses an enemy. It will move to the closest point (or farthest point, if ChooseFarthestPathPoint is used), on the path if it senses an enemy. StopBreakableMovement The helicopter can no longer disobey direct commands. It will continue to fly along it's patrol path or to it's specified target even if it senses an enemy. EnableRotorSound Starts the chopper's rotors making noise (normal behaviour) DisableRotorSound Stops the noise made by the rotors EnableRotorWash Makes the chopper exert a force on physics objects underneath its rotor, and produce a wind pattern on any water (normal behaviour) DisableRotorWash Turns off the forces and wind pattern SetAngles  !FGD InputStartLeading  !FGD InputStopLeading  !FGD
