Gunship doesn't follow info_node_air

I have a combine gunship in my single player map. It fires and
rotates but it doesn't move around. I have placed multiple
info_node_air in the map, but it seems to completely ignore them.

The other NPC's (i.e. manhacks) follow the info_node_air without any
problem. Do I have to do something different for the gunship?

In HL, the Apache had to use path_corners, as did the Osprey. And I'm
pretty sure in HL2, every gunship encounter had it on a set path,
flying around the player. So maybe try setting a path with path_corners
(which is even easier in Hammer, since it supports automatic instancing
if you just clone the path_corners).

Thanks, CJ. I thought you'd be right, but when I implemented the
path_corners, the gunship still hovered at the spawning location and
just rotated. It still shoots and stuff, but it just doesn't fly
around the perimeter like I wanted it to.

Now I am really stumped. I have no idea how to make it work.

The sdk_d2_coast_12 example map has a combine dropship set-up. It seems
to used path_tracks as the path, and gets a
"FlyToSpecificTrackViaPath" input to activate it.

The gunship is probably similar.

Hmm, I just decompiled a map with a gunship fight (d2_coast_04 - after
doing the bit with the crane and magnet), and it's got a really complex
entity set-up. It has any number of path_tracks defined, and the
gunship takes "SetTrack" and "StartPatrol" inputs.

After converting all the path_corners I initially set up to path_tracks
and using a trigger to "StartPatrol", the gunships works like a dream
now.

My setup isn't overly complicated, as it doesn't have any branching
point in the path_track loop. However, it stills works charmingly
and the gunship fights like a mad dog.

Thanks Rof. You didn't set your answer as "Possible Solution", so I cannot set your response as "Correct".

if you can get it to ignore the player please post it here, i am using an npc helicopter , from reading these posts im guessing it works similar to what your using. no matter what i try the helicopter swings round to face me as soon as, as far as i can figure, it notices me as it fly ahead, then it continues itsset path, i have tried all kinds of things, even setting up relationships and turning off agressive behaviour, plz help me out here .
