That is a consequence of the time it takes for the communication between AM and the sim. You are asking this link to execute 10 commands instantly. AFAIK there is no buffer that will ensure every command however quickly actioned gets through. If you were to slow things down it should respond better.

You don’t need iic for this. It’s just a single hardware function that happens to use 2 boards as input. Once you can read each of the 8 inputs it’s a simple matter of some logic to give the functionality you describe. Quite straight forward.

What you posted should work if it's used in an instrument script rather than a hardware function script.

As Ralph said you can't generate any graphics from a hardware function script.

As Ralph already mentioned many of the add-on aircraft are doing there own custom thing rather than use sim default autopilot data and/or button events. Each of these custom implementations needs some level of customisation in the Air Manager instrument to cater for this. There is a growing selectio...

I'll leave @Corjan to look into that. If it's only a repeat of what you write then it's pretty useless but if it fully mirrors the sim state and its initial state is correct also then that is indeed desirable to implement.

I’d point you to what that returns. See what’s listed in the returns table. @Corjan should be able to explain further.

Not sure I follow. The mouse can also be moved out when using a panel. I see no difference.

Why would it behave differently on a panel? The issue was first flagged by using a panel.

This is something that I've recently looked into while investigating an issue on one of my instruments. I think its been this way for a while maybe even forever but it causes issues. I tested with a button but if it works the same for other release callback's they will all be affected. This happens ...

As mentioned the event subscribe does not return values. It’s basically the same function for MSFS as xpl_command_subscribe is for Xplane. It just provides a callback whenever a command/event is triggered. The misconception here is in the use of the term Bvar. So called Bvar’s are not variables but ...
