LoGetWindAtPoint in export.lua

[LowLee]

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 ?

[LowLee]

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)

[LowLee]

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.

[LowLee]

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.

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 )

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.

[LowLee]

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

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?
