Sorry if I'm betcomming a bit of a high maintenance customer 🙂

I found advice online on how to map the 2024 C208 condition lever axis to my Honeycomb Bravo axis - In the sim it's called "Condition Lever Axis"

I tried mapping mixture axis, and condition lever axis events and nothing would map to this in AAO.

Any idea what axis this is in AAO?

More broadly... Is there any way to find out what event is firing when a switch is flipped or a button is pressed or a lever is moved in the virtual cockpit?

First and foremost, check the MSFS Input Events, the tab called "MSFS IEs" on the event selection dialog. And use the filter function on that dialog. Input events and their bindings (BVars) are the preferred control method in both MSFS 2020 and 2024. Only a small number of developers are still using the classic SDK events. IEs and BVars are individual assets of each aircraft. They are only visible in AAO when it is connected to the sim and you are sitting in the cockpit (=they are not available in Offline Mode)

IIRC the condition levers are two Input events, which can also be written as their bindings (BVars), depending on use case. Be mindful that the condition levers aren't axis, they only have three values (0,1,2) and nothing in between.

It is not that simple. Only IEs and BVars are singular events that are fired when the mouse is used. In most cases a lot more is happening under the hood, events are not only being used for input but also in the actual simulation logic. Some components are triggering entire scripts, not just single events.

The best method is to first check the input events and their bindings (=either the IE is working directly, or you use an associated binding/BVar instead, whichever suits your use case better). If that fails, activate MSFS developer mode and open "Tools->Behaviors". Click back into the sim window, then hover the mouse over the knob/switch/lever that you are interested in and press Ctrl-G. This (in most cases) brings up the behavior code of this component. Look for the MouseRect and ...Interaction... Components, which will contain the code that is executed when you use the mouse (LeftSingle, LeftRelease, Drag, etc.) That is what you have to replicate in AAO.

Also, be mindful that there already are script collections available for the most common addon aircraft on flightsim.to.

Same, but using the Binding of the IE instead of the IE itself (there may be instances where this works better, especially for Buttons where you might have _Inc and _Dec bindings)

Thanks... that worked. I hadn't looked in MSFS IEs... Doh!
