I need to have mobiflight send L:Doors_Vis as 0 and 1 to remove the doors on a little helicopter in the sim.
I tried through changing the msfs2020 variable code of one but I can’t get it to work. Do I do it through mobiflight variables or changing an msfs variable code?
Would the toggle code be…
L:Doors_Vis, if($=0,1,0) to allow the single button I assign to toggle between 0/1?
Thanks in advance!

You need to change the Lvar value directly as input code
Try this code in the input config
(L:Doors_Vis, bool) ! (>L:Doors_Vis, bool)

@mellow fractal the somewhat confusing part is that there are two different scripting code systems in MobiFlight. The "Transform" modifiers and Value fields use NCalc which is a bit like Excel spreadsheet formulas.
That is the if($=0,1,0) stuff.
Then there is the other method which is RPN or reverse polish notation - and this happens inside MSFS2020 and 2024 via the WASM module (essentially a simulator plug-in that talks to MobiFlight and allows us to see inside the simulator context.
RPN is the (L:Doors_Vis, bool) stuff, and you cannot mix those two, because they are not happening in the same place.

Ok cool. But do I do this under inputs-msfs2020 variables or under mobiflight variables

HubHop presets (which are also the MSFS Simconnect presets in MobiFlight Connector) are all RPN.
so if it is a simulator local variable it has to happen in RPN
if you want to make an event that toggles the l-variable,
so the link above explains the RPN in detail,
but basically, to read a variable, you do:
(X:VariableName, unit)
where X is usually either A or L
depends on the way the aircraft was done
did the code Jaime gave you above work?
you can add that to the "Custom code" field in an input configuration
what that code does:
(L:Doors_Vis, bool) ! (>L:Doors_Vis, bool)
is it reads the value, inverts it (the exclamation mark operand) and then writes the inverted value back to the same variable - writing has that angled bracket denoting that we put a value to the varialbe.

MF variables exist only within the Mobiflight app. MSFS2020 knows nothing about them. Lvars are Local Variables that exist and are used in MSFS2020 to store values and often trigger actions.

and MobiFlight variables exist only linside MF Connector, not in the sim.

Ok this is what I assumed. I use that to create other variables for switches and to monitor variables. I’ll have to try it tomorrow but I appreciate the help. Not sure what RPN means though.

RPN = Reverse Polish Notation
