• 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.

    Hi everyone, I'm currently working on a PFD, but the screen is black. The HTML works fine in the webbrowser and the HTML file is correctly loaded into the flight sim.

    Extracting a gauge from the sim

    Hi guys, I would like to build my own gauge controls as a webpage to display on my tablet, with simple HTML/CSS/Javascript firing HEvents through AxisandOhs. All I need is for a way to extract the display of the panel (in this case, the CJ4 FMC) and embed it in the browser, in much the same way...

    MSFS MSFS 2020 SDK for Gauge Developers

    Hello, I didn't have a look at the latest SDK after the patch but as far as I know, there is still not much information for us C/C++ gauge developers. At this time, I would like to know if you have any clue about these questions: Is it possible to develop "modules" like we used to do...

    P3D v4 Shift and Rotation on Image causes wild distortion

    I'm new to XML gauge design, but this one has me completely stumped. I have an ADI bitmap for an electronic flight display. If I apply a Shift (or variable vertical FloatPosition) for pitch, no problem. As soon as I add a rotation for bank though, I get bizarre distortion that happens with or...

    P3D v4 What language to use?

    I could use some input. Years ago I created the FDSFX panel for sound effects controlled from inside the cockpit. A simple 2D panel where the simmer flips a switch and an audio recording would play. Right-clicking on the switch would give options such as auto-repeat, volume control and...

    With the recent news that P3D and FSW are "going 64-bits" and the changes in their support of (64-bits) add-ons I was wondering: "What are the technical and internal differences between DLL-powered gauges vrs XML-powered-gauges" What i've learned myself so far is that: A - DLL-powered-gauges...

    Request help with FSX/P3D toggle gauges and tooltips.

    Hi, I've been making a few XML gauges and am stuck on a few things. Understanding the differences of the old types vs new types is obviously confusing to a noob. I've been able to accomplish maybe 80% of what I've wanted but am stuck on a few items, mainly 3 separate things. #1 - I want to...

    FSX Lua or gauge to perform trim inputs under few conditions

    Hello, community. I was trying to modify an aircrat's flight dynamics so it would be able to pitch down once thrust is cut during the flare. Unfortunately, i wasn't able to achieve the desired effect. I then decided to cheat fsx by creating a lua or a gauge that will trim nose down by several...

    Hi, I start leaning xml as used in the fsx gauges and I have a few questions. 1. Can someone tell me what the scope is of the goto/jump and quit statements? Meaning are they only active within element, select or value or even in the whole gauge? 2. I have a third party addon that is reacting...
