• 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.

FSX Whats ASM Tweaking & SCASM

Hi Friends,
I need to know What is ASM Tweaking & SCASM, I am not from a programming background hence if you find of any tutorial on the same then it will be highly appreciated.
Is SCASM for FS2002, will it work in FSX.
I am developing a custom airport for FSX and need to add the following to it
1) An aircraft Hangar with opening and Closing doors based on NAV Radio frequency
2) Taxi lights that will turn on and off based on NAV Radio frequency, to prevent Runway Incursions at the airport.
3) Airport Announcements that will play a sound at a pre defined time.

Will ASM Tweaking & SCASM help me achieve this

See my reply in your other thread that is very similar:


SCASM is a compiler to make bgl files from source code. SCASM is not for one FS version only, but it can not make fsx or fs2004 mdl objects. It can make fs2002 style object code and also fs2004 style terrain scenery. What it makes exactly depends on the code you write for it.
