[Help] How to get the actual heading degrees in Lua

[Kersick 0]

Hello my name is Ian and i am new with LINDA and Lua , yesterday I was working on a script for my brother,he show the original script,in XML.
This is the script: 

(L:CDI source selected, enum) 1 == 

if{
    (A:NAV1 radial, degrees) (A:Plane heading degrees gyro, degrees)
    (>K:VOR1_SET)
} 
(L:CDI source selected, enum) 2 == 

if{
    (A:NAV2 radial, degrees) (A:Plane heading degrees gyro, degrees)
    (>K:VOR2_SET) 
}    
(P:Absolute time, seconds) (>L:time crs changed, seconds)

The script changes the Nav 1 or Nav 2 heading to the actual curse of the plane,i think that this value is on the degrees variable,so, my trouble is ,is there any function on LINDA to get that value?I find the function to set the VOR1 or VOR2  and the function to set the Heading degrees gyro but it doesn't work at all because I have to use a static float number.

Thanks for the help.

Hi Ian

I am familiar with many programming language but not the one you quote. XML is an eXtensible Markup Language for documenting not a scripting or programming language. To understand your question, I would need to know what you are trying to do, with what Flt Sim and how you want to display the information. 

You will find LUA functions handling VOR/NAV function in LINDA's common.lua (in /modules/linda/system under NAV). These use the FSUIPC offsets to access the stored values (see FSUIPC Document in /modules).

Hi Scot

Before all else, thanks for your reply.
That script was inside of the .XML script, I'm not a regular user of XML but also that script use the reverse polish notation.
As soon as I can,I'll try what you tell me and then I'll post if it worked.
Thanks.
