• 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.

    MSFS WASM module exception calling fclose()

    First of all, let me clarify that I am a complete newbie in coding in C++. I'm creating a WASM module (it's not a gauge), with a very very simple logging to a text file. void ModLog(void) { FILE* logfile = fopen("\\work\\mylogfile.log", "a"); fprintf(logfile, "%s \n", debugtext)...

    P3D v4 Camera View in C++ Gauge

    I’m still new to C++ gauge programming but wondering how you embed camera views (similar to using <texture name=“…> in XML) into a C++ gauge? The eventual output will be a FLIR type gauge in a 2D or VC gauge. Ive looked through the wiki and not found anything obvious apart from the texture and...

    C++ / WASM programmer required ( Position Filled )

    DC Designs has a ( small ) job for somebody who can program C++ and compile into WASM for Microsoft Flight Simulator. This is a single gauge that performs a single function based on an available Avar - probably very easy for somebody with the skills. PM me if you're interested. DCD

    MSFS Reading Cockpit Camera Position/offset

    Hi, Does anyone know if it's possible to read the camera position when in the cockpit view mode, or the offset of the camera from default view (xyz)? There are some camera simvars vaguely mentioned in the SDK but no real information is provided. I'd like to read the 'head' position of the...

    Attempting to set RECIP ENG MANIFOLD PRESSURE:1 , but it simply is not setting, even though the debug cout<< is running I can see that the SimConnect_SetDataOnSimObject function is working, so the problem has to be from another part of the code no? If someone can help me find the issue that...

    SimConnect in WASM? SimConnect.H DWORD error

    I'm attempting to use simConnect to control plane variables within a WASM module, but I keep getting these DWORD errors. I know a standard solution to solve DWORD would be to #include windows.h, but windows.h just comes up as missing for some reason, even after I link it and rebuild solution...
