Tree height and ai pilot altitude

[thedubl 43]

Hello! So I am making a script for insertion. My issue is even though I am using flyInHeight at 25, the ai pilot is not using the altitude from the ground, but also including tree height. When the helo gets to the waypoint its too high to rappel down. I have tried to setPos, but the helo goes back to the same alt. Any ideas how to ignore tree height? Besides this issue the script runs great. Just need to work this last bit out. I could increase the rappel height, but I really would like to keep it around 25 m max.

Thanks!

Found this. Maybe it ignores tree height :)

Thanks! It is better, but not 100% though. I guess the pilot also looks slope? I think I might as well increase the height for the rappel script unless anyone has another idea.

 

Thanks,

This is weird because I don't remember being limited with this command as I saw script that simulate a crash with an ai pilot. Weird.

If its for an insertion so the chopper does not need any other AI capabiilty (i.e., combat), my fly in formation script could work.  With it, the aircraft (or any object...your team could be all sitting on a flying couch), will move across the exact path you set, at exact height you set (ignoring trees or any obstacles)..  It only flies in an exact straight line though.  You could tweak it to stop at your rappel location, at which point normal AI could take over for hovering, and leaving after team rappels.

 

If you only have one chopper, set birdCount parameter to 1.

 

The script would probably have to be modified for chopper to decelerate as it neared rappel position, and then end the scirpt once at destination (the ai and your scripting would then take over to keep chopper in position during rappel).

I believe I found the answer to this. Once the helo gets to the _insertionWp1 it is waiting for the next command. So, it just hovers at its "low" hover, although it is not that low. I just increase the altitude in the rappelling script.

 

If a helo has no waypoints, it will assume a low hover without regard to this setting. https://community.bistudio.com/wiki/flyInHeight

 

johnnyboy, I will take look at this too, thanks.

 

Thanks for the help.

Removed, due to not thinking!

Should post a new topic for this one, as this has nothing to do with AI height and pilot attitude.  It helps keep the forums searchable and maximumly useful for all!

If you're trying to get a heli to a specific position for rappelling, I have a script in my advanced rappelling addon that's really good at this. Gets the heli to move w/in 1m or so of a specific position + altitude.

See the readme - there's a function that can handle all of this for you. However, if you don't want units to auto-rappel, you'd have to take a look at the source and modify the function to meet your needs.
