Does anyone know of a script to make this happen?
You can use the addAction command to create 2 menu items to do this, or you can have it as 2 radio calls.
The landing script would simply have the following code:
; Make the chopper land anywhere.
chopper flyInHeight 0
Now, to get the chopper to take off again, have another script with the following code:
; Make the chopper lift off.
chopper flyInHeight 30
Replace 30 with whatever altitude at which you really want the chopper to fly. Also, replace "chopper" with your helicopter's name.
One menu action or radio call would call the first script, while the other action or call would call the second script.
Optionally, you can combine this into a single script and use if-then statements to check if the chopper should land or take off. If you're interested in the 1-script idea, I can create an example.
