Check if unit has landed on a building

[Ciribob]

Is there anyway to determine in LUA if a helicopter has landed on the roof of a building? The inAir() function always returns true when you're on one unfortunately.

 

Is there a ray trace function that will hit a static object (so you can determine height above the building)?

 

Or is the only way to check if the unit has 0 velocity which you can then assume they're on something as it's unlikely they will hold a hover that stable?

 

Any ideas or pointers would be very helpful!

 

What I'm trying to achieve is I'd like helicopters with the CTLD script to be able to deploy a Stinger on the roof of a building.

 

Thanks!

Thanks for the info! I was thinking along the same lines with the velocity.

 

This is what i've come up with as a new inAir Function

 

function ctld.inAir(_heli)

   if _heli:inAir() == false then
       return false
   end
   
   -- less than 5 cm/s a second so landed
   if mist.vec.mag(_heli:getVelocity()) < 0.05 then
       return false
   end
   return true
end
