• 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.

Acceleration Values overwrite

Hi,

I am experimenting with Simconnect to try to "overwrite" the ACCELERATION BODY Z values.

However, when I setdata on simobject, the result did not take effect unless Ground Speed is above 1 knot. (I need it to be active at 0 knot to modify breakaway thrust). Also, I notice that when I set acceleration value, it does not overwrite but rather, "adds" onto the sim internal calculated value.

Any idea if this behaviour is correct or did I do something wrongly?

hr = SimConnect_AddToDataDefinition(hSimConnect, DEFINITION_ACCEL_Z, "ACCELERATION BODY Z", "Feet per second squared");
hr = SimConnect_SetDataOnSimObject(hSimConnect, DEFINITION_ACCEL_Z, SIMCONNECT_OBJECT_ID_USER, 0, 0, sizeof(bodyaccelz), &bodyaccelz);
 
Thats also what i have experienced as well. The only alternative is to calculate your own velocities and set the FSX velocities directly instead.
