Good evening,
Reading a lot of B-21-soaring 's javascript (present in many freeware) I was able to write a js that allows me to manage via a 3D button on the VC the extension/closure of a cargo door on an aircraft.
The animation of this opening is managed by the variable A:FLAPS HANDLE PERCENT.
I also wanted this door to be able to open in MSFS External view via two keys on the keyboard that are mapped to the RETRACT FLAPS (event FLAPS_UP) and EXTEND FLAPS (event FLAPS_DOWN).
There is also an visual effect displayed wihen this door is opening via an L;var PBV_TankDumping (boolean).
The code has already been written for the model/aircraft.xml and works very well when the door is controlled via the VC and a click on the 3D button.
Is it possible in the javascript to read a variable like A:FLAPS HANDLE PERCENT (it varies from 0 to 100 for a press on FLAPS DOWN) and to set the L:Var to display the effect?
I have read this afternoon a lot of topic on this subject without finding a reale solution to my problem.
One test of mine:
In DEV Mod - Windows - Behaviors - LocalVariables, I cann't see PBV_SwitchTank changing when KEY is press as PBV_TankDumping which does not want to be modificated.
[EDIT] I just modify my post to be more exhaustive, with the time management and the update cycle used.

}
