• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

MSFS20 Problem with DECREASE_DECISION_HEIGHT

I have a rotating knob that controls the decision height.
The XML code is as simple as expected:

Code: 
<CLOCKWISE_CODE>(&gt;K:INCREASE_DECISION_HEIGHT)</CLOCKWISE_CODE>
<ANTICLOCKWISE_CODE>(&gt;K:DECREASE_DECISION_HEIGHT)</ANTICLOCKWISE_CODE>

I roll the mouse forward and the decision height increases, 10 by 10 as expected, perfect.
But when I roll the mouse backward, it works well a few times, decreasing the value 10 by 10, before suddenly reaching 0. Very strange...
Same when I use the mouse button: if i decrease by keeping the button depressed, it decreases correctly 4 or 5 times, then directly sets the value to 0, as if there was a super-accelerator that decreases the value so quickly that it goes to 0 before giving you the time to see it.

This doesn't happen when increasing the value. I already used this in fs9, FSX and P3D and never noticed this problem before.

Did you ever notice the same?
Any idea?

Thanks.

[EDIT] I solved the problem using my own variable to manage decision height, but I consider this as a workaround. If you have any explanation, please let me know.

Just a guess, but there is probably a minimum decision height (maybe 100 ft) so if you try to enter a height less than that it goes to zero.
The problem would not exist with your own variable.

No, unfortunately not... I already thought about this and increased the decision height up to 400+. Then decreasing it quickly with the mouse wheel set it to 0 long before it reached 100. In fact, after 4 or 5 cycles, it turns back to 0 so if you are at 400, it normally decreases to 360 or 350, then directly to 0.
Obviously, I don't have any problem when I use my own variable.

Click to expand...
I don't get the same behaviour. I just attached the decision height events to a control in my own aircraft, monitored the decision height variable in simvars and it works perfectly fine. No sudden jumps. It works as expected with mouse click, mouse wheel and dragging. Do you get the same behaviour with any other events in that same code? Say the attitude indicator bars pitch? Or Kohlsman knob?
 
That's interesting, it probably means there is a problem in my model, even though I am not sure about this because there is no problem at all when I use my own variable.
No, I never saw the same behavior with other events, and I have many others... The decision height is the only one that causes this problem.
I will do some additional testing. First I will try to map the decision height on another control to see if it works differently, I will let you know.
 
You were right Anthony, once again :)
I mapped the increase/decrease decision height events on another control and it works perfectly.
There is definitely a problem in my model, I will look into it.
Thanks again for your help !!
