solved EFM: ed_fm_enable_debug_info() not working in multithread

[Jack McCoy]

It was "documented" that the force and moment components display only worked in the single-threaded version.

Now that there is only a multithread version, are there any plans of making this feature work?

I've just found the thread dealing with the MT issue. Can you please provide a simple mission with a script enabling the function? I'll then report this issue to devs.

Hi Flappie. The issue is not related to any mission and I wouldn't know how to enable via lua script (if even possible!).

This is related to development of my External Flight Model (EFM), in file ED_FM_Template.cpp.

The thread you found mentions the vectors not being displayed even when:

//ED_FM_Template.cpp
bool ed_fm_enable_debug_info()
{
    return showVectors;

    /*
    When set to true, DCS draws lines on the aircraft.
    The blue box is the center of mass, green line is net force vector, pink line is the velocity vector.
    */
}

This worked in single-thread and doesn't work in multi-thread.
 

I think the following is a related issue:

//ED_FM_Template.cpp
size_t ed_fm_debug_watch(int level, char *buffer, size_t maxlen)
{
    return sprintf_s(buffer, maxlen, "ENGINE RPM %f.0", engine.rpm);
}

In multi-thread, it does not display "ENGINE RPM NNNN" in the "extended" screen, i.e. pressing RCtrl-Pause twice. Am I looking in the right place?

I never tried in single-thread.

I've just found an internal report. The issue was reported internally a few months ago.

@Flappie For the vectors to display, this is required:

Saved Games\DCS\Config\autoexec.cfg : drawDebugGeometry = true

Thanks for your precious feedback.
