Magnetic Heading from Unit

[Mav87th]

Hi

In relation to editing Bankler's CASE1 recovery trainer i have managed to develop a script that can retrieve a named units magnetic heading from calculations off a table that has to be adjusted according to Date and theater (i used Grok to create the table for me - worked really good). The script is of course created for a carrier, but i guess it would work for any named unit.

If any of you are interested i can post the script here

Just keep in mind that magnetic declination may vary significantly in different parts of the same map. That difference could be as big as 15-20 degrees (Kola).

@Minsky exactly - hench the table that was created from lat long borders and the date the mission was to take place in. So say from -7°E to 51°E and 64°N to 76°N you get a table like this if you ask for a 1 deg resolution (which might be to fine a resolution, but it was to make sure)

@Minsky exactly - hench the table that was created from lat long borders and the date the mission was to take place in.

Ah, great, glad you catered for that!

I may have made a lot of other mistakes in the script, so keep up the critical mindset

Hi,

for Singleplayer, you can use built-in functions of DCS, e.g.:

local myaw = net.dostring_in("export", "return LoGetMagneticYaw()")
myaw = tonumber(myaw) * (180 / math.pi)
if myaw < 0 then myaw = myaw + 360 end
trigger.action.outText("magnetic yaw: " .. tostring(myaw), 5, true)

 

[Mav87th]

@ops thats pretty cool and hell of a lot easier  

Is it giving you any units magnetic heading? (replacing myaw with the unit name?)

Is there a similar functionality for MP so all clients can get the magnetic heading of a named unit?
