LoGetWindAtPoint in export.lua

Hi guys,

I know that the LoGetWindAtPoint() function returns the intensity of the wind vector in a precise world point.

I would like to know if there is another function to get the direction of the wind, because the only intensity is useless.

:helpsmilie:

No one can help me?

I'm trying to export wind data from some points in the map but I cant

Export.LoGetWindAtPoint ?

As I wrote in the first post, that function returns only the speed, I need the direction too

Where do you see that function?

the only one I see is:

Export.LoGetVectorWindVelocity = {x,y,z} -- vector of wind velocity (world axis)

True, but LoGetVectorWindVelocoty() returns the wind of your own position, if you need the wind of another point in the world it's useless.

If you use LoGetWindAtPoint(x, y, z) = number you can get the wind speed of a point in the world but you can't get the direction.

My question is...how to get the wind direction of an arbitrary point of the world?

LoGetVectorWindVelocity returns a vector right? Analyzing the vector should give you both speed and direction.

You are right, but I don't need the wind of my own position, I need the wind in a (x, y, z) point in the world.

LoGetVectorWindVeloxity returns the wind vector that there's in my position. If I am flying at 4000m over Tbilisi and I need the wind of Lochini airport I can't use that function.

Thanks Alex, is it also possible to get the air pressure at a specific point on the map? Makes using dynamic weather a whole lot easier.

Yes, it will be a great thing to get the pressure too. :smilewink:

LoGetWindAtPoint return wind vector at desired point

 

local vx,vy,vz,absolute_height = LoGetWindAtPoint(x,y,z,is_radio_alt)

 

to get direction of wind:

 

local direction_in_radians = math.atan2(vz,vx); (or math.atan2(-vz,vx) depends of what sign you prefer )

I thought it was a vector and I was trying to get values with pairs() func.. My fault... sorry :doh::doh:

Thanks for the answer Alex!

There is a manual with all the export functions?
