Change instrument and hardware behaviour based upon "sim/aircraft/view/acf_ICAO"

[colinparker1967]

I am in the process of putting together some "magic" buttons and instruments whose appearance and behaviours vary dependent upon the aircraft loaded in the sim.

Creating a subscription with a callback routine to update a variable with the ICAO reference does seem to work but there is always the risk that the rest of the code will run before the variable has been populated. I have tried including all of the setup code in the callback and also using coroutines to prevent this from happening but Air Manager -not unreasonably- only allows setup to happen in mainline code.

As always, there is probably a really simple answer staring me in the face but I cannot see it.

Any ideas?

Thanks in advance.

This should be applied at a panel level, which has to manage the arbitration
See my sample here, specifically in the logic.lua of the panel itself "AutoPanels - PA-28 & Other AIRCRAFTS - Panels Loader" and in the AutoConfig instrument "AutoPanels (SP) - TOOLS - AIRCRAFT AUTO CONFIG" :

Thanks for your help. Looks like I have just scratched the surface of what is possible.

Hi,
I have another method which works for me.

Using library's and (tables/static_data) I load only the necessary data.

Code: Select all

xpl_dataref_subscribe("sim/aircraft/view/acf_ICAO","STRING",function(icao)

---   if icao == table 1  then load (table 1 or static _data set 1)
---   if icao == table 2  then load (table 2 or static _data set 2)

end)

--Now you can load your library's
--I use library's for each airframe and tables to do different variants. 
--data sets will not load until told to, but will be available. In other words not out side of initial load.

Hi,

I quickly pulled out a instrument I worked on some time back. It will give you the gist of what I said before.
You will have to create the necessary .json and librarys to make it work but you can get the idea.
You could also add a sim check using the connected functions
So the possibilities are vast.

Code: Select all

if xpl_connected() then
  print("Wowsers, we are connected to X-Plane!")
end

if fs2020_connected() then
  print("Good heavens, we are connected to FS2020!")
end

Code: Select all
